Recent government efforts regarding tar sands  

SciTech Connect

Conclusions from a workshop on tar sands are discussed. The workshop participants came to 3 conclusions: any oil-impregnated rock that is mined or quarried and then processed on the surface should be considered tar sands; some physical parameter should be used to differentiate tar sands from heavy oils, e.g., viscosity; and the dividing line between tar sands and heavy oil should be a point above which there is not currently significant commercial production. The resulting definition states that tar sand is any consolidated or unconsolidated rock other than coal, oil shale, or gilsonite, that contains a hydrocarbonaceous material with a gas-free viscosity, measured at reservoir temperature, greater than 10,000 cp, or contains a hydrocarbonaceous material that is extracted from the mined or quarried rock. Some consideration of resuming tar sands leasing also is discussed.

Getty mines oil sands in California  

Science Conference Proceedings (OSTI)

A large deposit of oil-laden diatomaceous earth in the McKittrick oil field 40 miles west of Bakersfield, California, has resisted all efforts at production by standard means. Getty Oil Co. is in the pilot phase of a project to recover the Diatomite's oil by an open pit mining operation. It also could have significant implications for other California oil fields, possibly setting the stage for the mining of oil sands in shallow fields like Kern River, S. Belridge, and Lost Hills to maximize oil recovery. A report on the project is summarized. The Diatomite is estimated to have 500 million bbl of oil in reserves, of which 380 million bbl are recoverable. The estimated amount of recoverable oil exceeds the McKittrick field's cumulative production of 240 million bbl. A pilot plant was built to test solvent extraction method of recovering heavy oil. The multistep process involves a series of 6 extractors. The Lurgi retorting plant employs a 2-step heating process to separate hydrocarbons from crushed ore.

Policy Analysis of the Canadian Oil Sands Experience  

SciTech Connect

For those who support U.S. oil sands development, the Canadian oil sands industry is often identified as a model the U.S. might emulate, yielding financial and energy security benefits. For opponents of domestic oil sands development, the Canadian oil sands experience illustrates the risks that opponents of development believe should deter domestic policymakers from incenting U.S. oil sands development. This report does not seek to evaluate the particular underpinnings of either side of this policy argument, but rather attempts to delve into the question of whether the Canadian experience has relevance as a foundational model for U.S. oil sands development. More specifically, this report seeks to assess whether and how the Canadian oil sands experience might be predictive or instructive in the context of fashioning a framework for a U.S. oil sands industry. In evaluating the implications of these underpinnings for a prospective U.S. oil sands industry, this report concentrates on prospective development of the oil sands deposits found in Utah.

Microstructural characterization of a Canadian oil sand  

E-Print Network (OSTI)

The microstructure of oil sand samples extracted at a depth of 75 m from the estuarine Middle McMurray formation (Alberta, Canada) has been investigated by using high resolution 3D X-Ray microtomography ($\\mu$CT) and Cryo Scanning Electron Microscopy (CryoSEM). $\\mu$CT images evidenced some dense areas composed of highly angular grains surrounded by fluids that are separated by larger pores full of gas. 3D Image analysis provided in dense areas porosity values compatible with in-situ log data and macroscopic laboratory determinations, showing that they are representative of intact states. $\\mu$CT hence provided some information on the morphology of the cracks and disturbance created by gas expansion. The CryoSEM technique, in which the sample is freeze fractured within the SEM chamber prior to observation, provided pictures in which the (frozen) bitumen clearly appears between the sand grains. No evidence of the existence of a thin connate water layer between grains and the bitumen, frequently mentioned in th...

Sand control in horizontal wells in heavy-oil reservoirs  

SciTech Connect

Recent advances in horizontal-well technology has greatly improved the potential for heavy oil recovery. Such recovery may be hampered, however, by sanding problems associated with most heavy-oil reservoirs. These reservoir sands are mostly unconsolidated and may lead to severe productivity-loss problems if produced freely. This paper offers recommendations for sand control in three Canadian heavy-oil reservoirs. Experimental evidence has shown that minimizing the annular space between the casing and the open hole is important, especially in the case of smaller wire space, lower oil viscosity, and thinner pay zone. Several types of wire-wrapped screens and flexible liners were tested for sand control. Only flexible liners reduced sand production to a negligible amount.

GASIFICATION IN THE CANADIAN OIL SANDS:  

E-Print Network (OSTI)

The Long Lake integrated bitumen and upgrading project, now under construction by OPTI Canada Inc. and Nexen Inc., is the first application of large-scale gasification in Canada. It also represents the first implementation of a gasification project in conjunction with a heavy oil recovery and upgrading project. The Canadian oil sands are a vast petroleum resource that currently produces over one million barrels per day (bpd) using proven mining and in-situ recovery technologies. Production is projected to rise to over two million bpd by the end of the decade. However the large volumes of natural gas normally needed by the bitumen recovery and upgrading facilities are a significant barrier to economic development of the resource. The Long Lake Project uses a unique combination of technologies to provide a solution to the natural gas supply and cost issue. A key component is a gasification facility using the Shell Gasification Process (SGP) which is integrated with the bitumen upgrading to convert the liquid asphaltene by-product stream into hydrogen for the secondary upgrading step and syngas fuel. An Air Liquide air separation unit (ASU) will provide

Recovery of heavy crude oil or tar sand oil or bitumen from underground formations  

SciTech Connect

This patent describes a method of producing heavy crude oil or tar sand oil or bitumen from an underground formation. The method consists of utilizing or establishing an aqueous fluid communication path within and through the formation between an injection well or conduit and a production well or conduit by introducing into the formation from the injection well or conduit hot water and/or low quality steam at a temperature in the range about 60{sup 0}-130{sup 0}C and at a substantially neutral or alkaline pH to establish or enlarge the aqueous fluid communication path within the formation from the injection well or conduit to the production well or conduit by movement of the introduced hot water or low quality steam through the formation, increasing the temperature of the injected hot water of low quality steam to a temperature in the range about 110{sup 0}-180{sup 0}C while increasing the pH of the injected hot water or low quality steam to a pH of about 10-13 so as to bring about the movement or migration or stripping of the heavy crude oil or tar sand oil or bitumen from the formation substantially into the hot aqueous fluid communication path with the formation and recovering the resulting produced heavy crude oil or tar sand oil or bitumen from the formation as an emulsion containing less than about 30% oil or bitumen from the production well or conduit.

Retention behavior of dilute polymers in oil sands  

Science Conference Proceedings (OSTI)

Adequate mobility control between fluid banks is a pertinent factor in the successful application of secondary and tertiary oil recovery processes. Favorable mobilities can be obtained by increasing the viscosity or reducing the permeability to the displacing fluid phase. Polyacrylamide and oio-polymers have proved to be useful for these purposes. These polymers increase the water viscosity substantially at low concentrations. The resulting reduced mobility of the displacing phase suppresses the fingering phenomenon and improves piston-like displacement. However, the structural complexity of these polymers coupled with the complexity of the flow channels in the porous medium cause part of these polymers to be retained in the reservoir as the displacing fluid from advances, thereby causing a reduction in the concentration of the polymer solution and consequently a loss of mobility control. In addition to the mechanical filtering, adsorption on the grain surfaces reduce the polymer concentration in the displacing fluid. Behavior of polyacrylamide polymers has been studied extensively. Susceptibility of these polymers to salinity, pH, shear, temperature, etc., is well documented. Mechanical entrapment, retention, degradation and adsorption behavior on porous media, including fired Berea sandstone, bead packs and Ottawa sand have been reported. The present study investigates the adsorption and trapping of polymers in flow experiments through unconsolidated oil field sands. Effects of particle size and mineral content have been studied. Effect of a surfactant slug on polymer-rock interaction is also reported. Corroborative studies have been conducted to study the pressure behavior and high tertiary oil recovery in surfactant dilute-polymer systems.

Trace metals in heavy crude oils and tar sand bitumens  

SciTech Connect

Fe, Ni, and V are considered trace impurities in heavy crude oils and tar sand bitumens. In order to understand the importance of these metals, we have examined several properties: (1) bulk metals levels, (2) distribution in separated fractions, (3) size behavior in feeds and during processing, (4) speciation as a function of size, and (5) correlations with rheological properties. Some of the results of these studies show: (1) V and Ni have roughly bimodal size distributions, (2) groupings were seen based on location, size distribution, and Ni/V ratio of the sample, (3) Fe profiles are distinctively different, having a unimodal distribution with a maximum at relatively large molecular size, (4) Fe concentrations in the tar sand bitumens suggest possible fines solubilization in some cases, (5) SARA separated fractions show possible correlations of metals with asphaltene properties suggesting secondary and tertiary structure interactions, and (6) ICP-MS examination for soluble ultra-trace metal impurities show the possibility of unexpected elements such as U, Th, Mo, and others at concentrations in the ppB to ppM range. 39 refs., 13 figs., 5 tabs.

Integration of High Temperature Gas-cooled Reactor Technology with Oil Sands Processes  

Science Conference Proceedings (OSTI)

This paper summarizes an evaluation of siting an HTGR plant in a remote area supplying steam, electricity and high temperature gas for recovery and upgrading of unconventional crude oil from oil sands. The area selected for this evaluation is the Alberta Canada oil sands. This is a very fertile and active area for bitumen recovery and upgrading with significant quantities piped to refineries in Canada and the U.S Additionally data on the energy consumption and other factors that are required to complete the evaluation of HTGR application is readily available in the public domain. There is also interest by the Alberta oil sands producers (OSP) in identifying alternative energy sources for their operations. It should be noted, however, that the results of this evaluation could be applied to any similar oil sands area.

Paleontological overview of oil shale and tar sands areas in Colorado, Utah, and Wyoming.  

Science Conference Proceedings (OSTI)

In August 2005, the U.S. Congress enacted the Energy Policy Act of 2005, Public Law 109-58. In Section 369 of this Act, also known as the ''Oil Shale, Tar Sands, and Other Strategic Unconventional Fuels Act of 2005,'' Congress declared that oil shale and tar sands (and other unconventional fuels) are strategically important domestic energy resources that should be developed to reduce the nation's growing dependence on oil from politically and economically unstable foreign sources. In addition, Congress declared that both research- and commercial-scale development of oil shale and tar sands should (1) be conducted in an environmentally sound manner using management practices that will minimize potential impacts, (2) occur with an emphasis on sustainability, and (3) benefit the United States while taking into account concerns of the affected states and communities. To support this declaration of policy, Congress directed the Secretary of the Interior to undertake a series of steps, several of which are directly related to the development of a commercial leasing program for oil shale and tar sands. One of these steps was the completion of a programmatic environmental impact statement (PEIS) to analyze the impacts of a commercial leasing program for oil shale and tar sands resources on public lands, with an emphasis on the most geologically prospective lands in Colorado, Utah, and Wyoming. For oil shale, the scope of the PEIS analysis includes public lands within the Green River, Washakie, Uinta, and Piceance Creek Basins. For tar sands, the scope includes Special Tar Sand Areas (STSAs) located in Utah. This paleontological resources overview report was prepared in support of the Oil Shale and Tar Sands Resource Management Plan Amendments to Address Land Use Allocations in Colorado, Utah, and Wyoming and PEIS, and it is intended to be used by Bureau of Land Management (BLM) regional paleontologists and field office staff to support future projectspecific analyses. Additional information about the PEIS can be found at http://ostseis.anl.gov.

The extraction of bitumen from western oil sands. Annual report, July 1991--July 1992  

SciTech Connect

The University of Utah tar sand research and development program is concerned with research and development on Utah is extensive oil sands deposits. The program has been intended to develop a scientific and technological base required for eventual commercial recovery of the heavy oils from oil sands and processing these oils to produce synthetic crude oil and other products such as asphalt. The overall program is based on mining the oil sand, processing the mined sand to recover the heavy oils and upgrading them to products. Multiple deposits are being investigated since it is believed that a large scale (approximately 20,000 bbl/day) plant would require the use of resources from more than one deposit. The tasks or projects in the program are organized according to the following classification: Recovery technologies which includes thermal recovery methods, water extraction methods, and solvent extraction methods; upgrading and processing technologies which covers hydrotreating, hydrocracking, and hydropyrolysis; solvent extraction; production of specialty products; and environmental aspects of the production and processing technologies. These tasks are covered in this report.

Policy Analysis of Water Availability and Use Issues for Domestic Oil Shale and Oil Sands Development  

Science Conference Proceedings (OSTI)

Oil shale and oil sands resources located within the intermountain west represent a vast, and as of yet, commercially untapped source of energy. Development will require water, and demand for scarce water resources stands at the front of a long list of barriers to commercialization. Water requirements and the consequences of commercial development will depend on the number, size, and location of facilities, as well as the technologies employed to develop these unconventional fuels. While the details remain unclear, the implication is not – unconventional fuel development will increase demand for water in an arid region where demand for water often exceeds supply. Water demands in excess of supplies have long been the norm in the west, and for more than a century water has been apportioned on a first-come, first-served basis. Unconventional fuel developers who have not already secured water rights stand at the back of a long line and will need to obtain water from willing water purveyors. However, uncertainty regarding the nature and extent of some senior water claims combine with indeterminate interstate river management to cast a cloud over water resource allocation and management. Quantitative and qualitative water requirements associated with Endangered Species protection also stand as barriers to significant water development, and complex water quality regulations will apply to unconventional fuel development. Legal and political decisions can give shape to an indeterminate landscape. Settlement of Northern Ute reserved rights claims would help clarify the worth of existing water rights and viability of alternative sources of supply. Interstate apportionment of the White River would go a long way towards resolving water availability in downstream Utah. And energy policy clarification will help determine the role oil shale and oil sands will play in our nation’s future.

BIOTIGER, A NATURAL MICROBIAL PRODUCT FOR ENHANCED HYDROCARBON RECOVERY FROM OIL SANDS.  

SciTech Connect

BioTiger{trademark} is a unique microbial consortia that resulted from over 8 years of extensive microbiology screening and characterization of samples collected from a century-old Polish waste lagoon. BioTiger{trademark} shows rapid and complete degradation of aliphatic and aromatic hydrocarbons, produces novel surfactants, is tolerant of both chemical and metal toxicity and shows good activity at temperature and pH extremes. Although originally developed and used by the U.S. Department of Energy for bioremediation of oil-contaminated soils, recent efforts have proven that BioTiger{trademark} can also be used to increase hydrocarbon recovery from oil sands. This enhanced ex situ oil recovery process utilizes BioTiger{trademark} to optimize bitumen separation. A floatation test protocol with oil sands from Ft. McMurray, Canada was used for the BioTiger{trademark} evaluation. A comparison of hot water extraction/floatation test of the oil sands performed with BioTiger{trademark} demonstrated a 50% improvement in separation as measured by gravimetric analysis in 4 h and a five-fold increase at 25 hr. Since BioTiger{trademark} performs well at high temperatures and process engineering can enhance and sustain metabolic activity, it can be applied to enhance recovery of hydrocarbons from oil sands or other complex recalcitrant matrices.

Definition of heavy oil and natural bitumen  

Science Conference Proceedings (OSTI)

Definition and categorization of heavy oils and natural bitumens are generally based on physical or chemical attributes or on methods of extraction. Ultimately, the hydrocarbon's chemical composition will govern both its physical state and the extraction technique applicable. These oils and bitumens closely resemble the residuum from wholecrude distillation to about 1,000/degree/F; if the residuum constitutes at least 15% of the crude, it is considered to be heavy. In this material is concentrated most of the trace elements, such as sulfur, oxygen, and nitrogen, and metals, such as nickel and vanadium. A widely used definition separates heavy oil from natural bitumen by viscosity, crude oil being less, and bitumen more viscous than 10,000 cp. Heavy crude then falls in the range 10/degree/-20/degree/ API inclusive and extra-heavy oil less than 10/degree/ API. Most natural bitumen is natural asphalt (tar sands, oil sands) and has been defined as rock containing hydrocarbons more viscous than 10,000 cp or else hydrocarbons that may be extracted from mined or quarried rock. Other natural bitumens are solids, such as gilsonite, grahamite, and ozokerite, which are distinguished by streak, fusibility, and solubility. The upper limit for heavy oil may also be set at 18/degree/ API, the approximate limit for recovery by waterflood.

Temperature effects on oil-water relative permeabilities for unconsolidated sands  

SciTech Connect

This study presents an experimental investigation of temperature effects on relative permeabilities of oil- water systems in unconsolidated sands. The fluids used in this study were refined mineral oil and distilled water. A rate sensitivity study was done on residual oil saturation and oil and water relative permeabilities. The temperature sensitivity study of relative permeabilities was conducted in 2 parts. The first was to investigate changes in residual oil saturation with temperature where the cores were 100% saturated with oil at the start of the waterflood. The second part continued the floods for a longer time until the water-cut was virtually 100%. Under these conditions, little change in residual oil saturation was observed with temperature. A study on viscous instabilities also was performed. This verified the existence of viscous fingers during waterflooding. It also was observed that tubing volume after the core could cause fingering, resulting in lower apparent breakthrough oil recoveries.

Pore Scale Analysis of Oil Shale/Sands Pyrolysis  

SciTech Connect

There are important questions concerning the quality and volume of pore space that is created when oil shale is pyrolyzed for the purpose of producing shale oil. In this report, 1.9 cm diameter cores of Mahogany oil shale were pyrolyzed at different temperatures and heating rates. Detailed 3D imaging of core samples was done using multiscale X-ray computed tomography (CT) before and after pyrolysis to establish the pore structure. The pore structure of the unreacted material was not clear. Selected images of a core pyrolyzed at 400oC were obtained at voxel resolutions from 39 microns (?m) to 60 nanometers (nm). Some of the pore space created during pyrolysis was clearly visible at these resolutions and it was possible to distinguish between the reaction products and the host shale rock. The pore structure deduced from the images was used in Lattice Boltzmann simulations to calculate the permeability in the pore space. The permeabilities of the pyrolyzed samples of the silicate-rich zone were on the order of millidarcies, while the permeabilities of the kerogen-rich zone after pyrolysis were very anisotropic and about four orders of magnitude higher.

Diamonds in the rough: identification of individual napthenic acids in oil sands process water  

Science Conference Proceedings (OSTI)

Expansion of the oil sands industry of Canada has seen a concomitant increase in the amount of process water produced and stored in large lagoons known as tailings ponds. Concerns have been raised, particularly about the toxic complex mixtures of water-soluble naphthenic acids (NA) in the process water. To date, no individual NA have been identified, despite numerous attempts, and while the toxicity of broad classes of acids is of interest, toxicity is often structure-specific, so identification of individual acids may also be very important. The chromatographic resolution and mass spectral identification of some individual NA from oil sands process water is described. The authors concluded that the presence of tricyclic diamondoid acids, never before even considered as NA, suggests an unprecedented degree of biodegradation of some of the oil in the oil sands. The identifications reported should now be followed by quantitative studies, and these used to direct toxicity assays of relevant NA and the method used to identify further NA to establish which, or whether all NA, are toxic. The two-dimensional comprehensive gas chromatography-mass spectrometry method described may also be important for helping to better focus reclamation/remediation strategies for NA as well as in facilitating the identification of the sources of NA in contaminated surface waters (auth)

Class I cultural resource overview for oil shale and tar sands areas in Colorado, Utah and Wyoming.  

Science Conference Proceedings (OSTI)

In August 2005, the U.S. Congress enacted the Energy Policy Act of 2005, Public Law 109-58. In Section 369 of this Act, also known as the 'Oil Shale, Tar Sands, and Other Strategic Unconventional Fuels Act of 2005', Congress declared that oil shale and tar sands (and other unconventional fuels) are strategically important domestic energy resources that should be developed to reduce the nation's growing dependence on oil from politically and economically unstable foreign sources. The Bureau of Land Management (BLM) is developing a Programmatic Environmental Impact Statement (PEIS) to evaluate alternatives for establishing commercial oil shale and tar sands leasing programs in Colorado, Wyoming, and Utah. This PEIS evaluates the potential impacts of alternatives identifying BLM-administered lands as available for application for commercial leasing of oil shale resources within the three states and of tar sands resources within Utah. The scope of the analysis of the PEIS also includes an assessment of the potential effects of future commercial leasing. This Class I cultural resources study is in support of the Draft Oil Shale and Tar Sands Resource Management Plan Amendments to Address Land Use Allocations in Colorado, Utah, and Wyoming and Programmatic Environmental Impact Statement and is an attempt to synthesize archaeological data covering the most geologically prospective lands for oil shale and tar sands in Colorado, Utah, and Wyoming. This report is based solely on geographic information system (GIS) data held by the Colorado, Utah, and Wyoming State Historic Preservation Offices (SHPOs). The GIS data include the information that the BLM has provided to the SHPOs. The primary purpose of the Class I cultural resources overview is to provide information on the affected environment for the PEIS. Furthermore, this report provides recommendations to support planning decisions and the management of cultural resources that could be impacted by future oil shale and tar sands resource development.

True in-situ bed preparation: oil shale and tar sand  

SciTech Connect

In 1978, a detailed study was conducted to evaluate the status of the bed preparation technology that had been developed for true in-situ processing of oil shale. It was concluded that the two techniques which had received the bulk of the attention in prior field experimentation, namely the wellbore springing and hydraulic/explosive fracturing concepts, both had inherent traits which would prevent them from being useful in practical applications. In the current paper, the previous results are reviewed to determine whether or not they are also applicable to tar sand. The conclusion reached is that neither technique would be practical for preparing a tar sands deposit for in-situ processing.

Sovent Based Enhanced Oil Recovery for In-Situ Upgrading of Heavy Oil Sands  

Science Conference Proceedings (OSTI)

With the depletion of conventional crude oil reserves in the world, heavy oil and bitumen resources have great potential to meet the future demand for petroleum products. However, oil recovery from heavy oil and bitumen reservoirs is much more difficult than that from conventional oil reservoirs. This is mainly because heavy oil or bitumen is partially or completely immobile under reservoir conditions due to its extremely high viscosity, which creates special production challenges. In order to overcome these challenges significant efforts were devoted by Applied Research Center (ARC) at Florida International University and The Center for Energy Economics (CEE) at the University of Texas. A simplified model was developed to assess the density of the upgraded crude depending on the ratio of solvent mass to crude oil mass, temperature, pressure and the properties of the crude oil. The simplified model incorporated the interaction dynamics into a homogeneous, porous heavy oil reservoir to simulate the dispersion and concentration of injected CO{sub 2}. The model also incorporated the characteristic of a highly varying CO{sub 2} density near the critical point. Since the major challenge in heavy oil recovery is its high viscosity, most researchers have focused their investigations on this parameter in the laboratory as well as in the field resulting in disparaging results. This was attributed to oil being a complex poly-disperse blend of light and heavy paraffins, aromatics, resins and asphaltenes, which have diverse behaviors at reservoir temperature and pressures. The situation is exacerbated by a dearth of experimental data on gas diffusion coefficients in heavy oils due to the tedious nature of diffusivity measurements. Ultimately, the viscosity and thus oil recovery is regulated by pressure and its effect on the diffusion coefficient and oil swelling factors. The generation of a new phase within the crude and the differences in mobility between the new crude matrix and the precipitate readily enables removal of asphaltenes. Thus, an upgraded crude low in heavy metal, sulfur and nitrogen is more conducive for further purification.

Dependence of waterflood remaining oil saturation on relative permeability, capillary pressure, and reservoir parameters in mixed-wet turbidite sands  

SciTech Connect

The dependence of waterflood oil recovery on relative permeability, capillary pressure, and reservoir parameters was investigated by numerical simulation. The relative permeability and capillary pressure curves were based on laboratory measurements on unconsolidated sands. The water-wet case is based on the assumption that the system is water-wet and measurements were made with refined oil. The mixed-wet case assumed that the system is mixed-wet and restored-state measurements were made with crude oil. The reservoir model was a prototype turbidite sand with a range of thickness and permeability values. The economic oil recovery was based on an economic limit water cut of 50%. The remaining oil saturation (ROS) in the swept region for the water-wet cases was close to the residual oil saturation. The ROS of the mixed-wet cases ranged from low values near the residual oil saturation to far above the residual oil saturation. It is dependent on the reservoir parameters that govern (1) the vertical film surface drainage of oil by gravity, (2) accumulation of a high oil saturation and thus a high relative permeability under the caprock, and (3) up-dip migration of the oil that accumulated under the caprock. The dependence on the reservoir parameters can be summarized by dimensionless groups. There is a dimensionless time for the vertical displacement of oil by gravity. The accumulation of a high oil saturation under the caprock is dependent on the ratio of the capillary transition zone and the sand thickness. The updip migration is dependent on a combination of the gravity number and the endpoint mobility ratio.

Evolution of seismic velocities in heavy oil sand reservoirs during thermal recovery process  

E-Print Network (OSTI)

In thermally enhanced recovery processes like cyclic steam stimulation (CSS) or steam assisted gravity drainage (SAGD), continuous steam injection entails changes in pore fluid, pore pressure and temperature in the rock reservoir, that are most often unconsolidated or weakly consolidated sandstones. This in turn increases or decreases the effective stresses and changes the elastic properties of the rocks. Thermally enhanced recovery processes give rise to complex couplings. Numerical simulations have been carried out on a case study so as to provide an estimation of the evolution of pressure, temperature, pore fluid saturation, stress and strain in any zone located around the injector and producer wells. The approach of Ciz and Shapiro (2007) - an extension of the poroelastic theory of Biot-Gassmann applied to rock filled elastic material - has been used to model the velocity dispersion in the oil sand mass under different conditions of temperature and stress. A good agreement has been found between these pre...

QUANTITATIVE METHODS FOR RESERVOIR CHARACTERIZATION AND IMPROVED RECOVERY: APPLICATION TO HEAVY OIL SANDS  

SciTech Connect

Improved prediction of interwell reservoir heterogeneity has the potential to increase productivity and to reduce recovery cost for California's heavy oil sands, which contain approximately 2.3 billion barrels of remaining reserves in the Temblor Formation and in other formations of the San Joaquin Valley. This investigation involves application of advanced analytical property-distribution methods conditioned to continuous outcrop control for improved reservoir characterization and simulation, particularly in heavy oil sands. The investigation was performed in collaboration with Chevron Production Company U.S.A. as an industrial partner, and incorporates data from the Temblor Formation in Chevron's West Coalinga Field. Observations of lateral variability and vertical sequences observed in Temblor Formation outcrops has led to a better understanding of reservoir geology in West Coalinga Field. Based on the characteristics of stratigraphic bounding surfaces in the outcrops, these surfaces were identified in the subsurface using cores and logs. The bounding surfaces were mapped and then used as reference horizons in the reservoir modeling. Facies groups and facies tracts were recognized from outcrops and cores of the Temblor Formation and were applied to defining the stratigraphic framework and facies architecture for building 3D geological models. The following facies tracts were recognized: incised valley, estuarine, tide- to wave-dominated shoreline, diatomite, and subtidal. A new minipermeameter probe, which has important advantages over previous methods of measuring outcrop permeability, was developed during this project. The device, which measures permeability at the distal end of a small drillhole, avoids surface weathering effects and provides a superior seal compared with previous methods for measuring outcrop permeability. The new probe was used successfully for obtaining a high-quality permeability data set from an outcrop in southern Utah. Results obtained from analyzing the fractal structure of permeability data collected from the southern Utah outcrop and from core permeability data provided by Chevron from West Coalinga Field were used in distributing permeability values in 3D reservoir models. Spectral analyses and the Double Trace Moment method (Lavallee et al., 1991) were used to analyze the scaling and multifractality of permeability data from cores from West Coalinga Field. T2VOC, which is a numerical flow simulator capable of modeling multiphase, multi-component, nonisothermal flow, was used to model steam injection and oil production for a portion of section 36D in West Coalinga Field. The layer structure and permeability distributions of different models, including facies group, facies tract, and fractal permeability models, were incorporated into the numerical flow simulator. The injection and production histories of wells in the study area were modeled, including shutdowns and the occasional conversion of production wells to steam injection wells. The framework provided by facies groups provides a more realistic representation of the reservoir conditions than facies tracts, which is revealed by a comparison of the history-matching for the oil production. Permeability distributions obtained using the fractal results predict the high degree of heterogeneity within the reservoir sands of West Coalinga Field. The modeling results indicate that predictions of oil production are strongly influenced by the geologic framework and by the boundary conditions. The permeability data collected from the southern Utah outcrop, support a new concept for representing natural heterogeneity, which is called the fractal/facies concept. This hypothesis is one of the few potentially simplifying concepts to emerge from recent studies of geological heterogeneity. Further investigation of this concept should be done to more fully apply fractal analysis to reservoir modeling and simulation. Additional outcrop permeability data sets and further analysis of the data from distinct facies will be needed in order to fully develop

Technology assessment: environmental, health, and safety impacts associated with oil recovery from US tar-sand deposits  

SciTech Connect

The tar-sand resources of the US have the potential to yield as much as 36 billion barrels (bbls) of oil. The tar-sand petroleum-extraction technologies now being considered for commercialization in the United States include both surface (above ground) systems and in situ (underground) procedures. The surface systems currently receiving the most attention include: (1) thermal decomposition processes (retorting); (2) suspension methods (solvent extraction); and (3) washing techniques (water separation). Underground bitumen extraction techniques now being field tested are: (1) in situ combustion; and (2) in situ steam-injection procedures. At this time, any commercial tar-sand facility in the US will have to comply with at least 7 major federal regulations in addition to state regulations; building, electrical, and fire codes; and petroleum-industry construction standards. Pollution-control methods needed by tar-sand technologies to comply with regulatory standards and to protect air, land, and water quality will probably be similar to those already proposed for commercial oil-shale systems. The costs of these systems could range from about $1.20 to $2.45 per barrel of oil produced. Estimates of potential pollution-emisson levels affecting land, air, and water were calculated from available data related to current surface and in situ tar-sand field experiments in the US. These data were then extrapolated to determine pollutant levels expected from conceptual commercial surface and in situ facilities producing 20,000 bbl/d. The likelihood-of-occurrence of these impacts was then assessed. Experience from other industries, including information concerning health and ecosystem damage from air pollutants, measurements of ground-water transport of organic pollutants, and the effectiveness of environmental-control technologies was used to make this assessment.

Environmental, health, safety, and socioeconomic concerns associated with oil recovery from US tar-sand deposits: state-of-knowledge  

SciTech Connect

Tar-sand petroleum-extraction procedures undergoing field testing for possible commercial application in the US include both surface (above-ground) and in situ (underground) procedures. The surface tar-sand systems currently being field tested in the US are thermal decomposition processes (retorting), and suspension methods (solvent extraction). Underground bitumen extraction procedures that are also being field tested domestically are in situ combustion and steam-injection. Environmental, health, safety, and socioeconomic concerns associated with construction and operation of 20,000-bbl/d commercial tar-sand surface and in situ facilities have been estimated and are summarized in this report. The principal regulations that commercial tar-sand facilities will need to address are also discussed, and environmental control technologies are summarized and wherever possible, projected costs of emission controls are stated. Finally, the likelihood-of-occurrence of potential environmental, health, and safety problems that have been determined are reviewed, and from this information inference is made as to the environmental acceptability of technologically feasible 20,000-bbl/d commercial tar-sand oil-extraction procedures.

Effect of temperature on oil/water relative permeabilities of unconsolidated and consolidated sands  

SciTech Connect

Over the last 20 years, a number of studies have reported temperature effects on two-phase relative permeabilities in porous media. However, some of the reported results have been contradictory. Also, observed effects have not been explained in terms of fundamental properties known to govern two-phase flow. The purpose of this study was to attempt to isolate the fundamental properties affecting two-phase relative permeabilities at elevated temperature. Laboratory dynamic displacement relative permeability measurements were made on unconsolidated and consolidated sand cores, using water and a refined white mineral oil. Experiments were run on 2 in. (51 mm) diameter, 20 in. (510 mm) long cores from room temperature to 300/sup 0/F (149/sup 0/C). Unlike the results of previous researchers, essentially no changes with temperatures were observed in either residual saturations or relative permeability relationships. It was concluded that previous results may have been affected by viscous instabilities, capillary end-effects, and/or difficulties in maintaining material balances.

Supplying Synthetic Crude Oil from Canadian Oil Sands: A Comparative Study of the Costs and CO2 Emissions of Mining and In-situ Recovery  

E-Print Network (OSTI)

High crude oil prices and the eventual decline of conventional oil production raise the issue of alternative fuels such as non-conventional oil. The paper describes a simple probabilistic model of the costs of synthetic crude oil (SCO) produced from Canadian oil sands. Synthetic crude oil is obtained by upgrading bitumen that is first produced through mining or in-situ recovery techniques. This forward-looking analysis quantifies the effects of learning and production constraints on the costs of supplying synthetic crude oil from Canadian bitumen deposits. The results show the uncertainties associated with the future costs of synthetic crude oil. Carbon costs have a large impact of the total costs of synthetic crude oil, in particular in the case of synthetic crude oil from in-situ bitumen, due to the carbon-intensity of the recovery techniques. The influence of each parameter on the supply costs is examined. In the case of mined SCO, the maximum production rate, the ultimate recovery rate and the depletion parameters show the largest influence on the results, while learning parameters dominate in the case of in-situ SCO.

Constitutive models for the Etchegoin Sands, Belridge Diatomite, and overburden formations at the Lost Hills oil field, California  

SciTech Connect

This report documents the development of constitutive material models for the overburden formations, reservoir formations, and underlying strata at the Lost Hills oil field located about 45 miles northwest of Bakersfield in Kern County, California. Triaxial rock mechanics tests were performed on specimens prepared from cores recovered from the Lost Hills field, and included measurements of axial and radial stresses and strains under different load paths. The tested intervals comprise diatomaceous sands of the Etchegoin Formation and several diatomite types of the Belridge Diatomite Member of the Monterey Formation, including cycles both above and below the diagenetic phase boundary between opal-A and opal-CT. The laboratory data are used to drive constitutive parameters for the Extended Sandler-Rubin (ESR) cap model that is implemented in Sandia's structural mechanics finite element code JAS3D. Available data in the literature are also used to derive ESR shear failure parameters for overburden formations. The material models are being used in large-scale three-dimensional geomechanical simulations of the reservoir behavior during primary and secondary recovery.

Development of CFD-Based Simulation Tools for In-Situ Thermal Processing of Oil Shale/Sands  

Science Conference Proceedings (OSTI)

In our research, we are taking the novel approach of developing and applying high performance computing, computational fluid dynamics (CFD)-based simulation tools to a modified in-situ process for production of oil from oil shale. The simulation tools being developed capture the relevant physical processes and data from a large-scale system. The modified in-situ application is a pilot-scale heat transfer process inside Red Leaf Resourcesâ?? EcoShale capsule. We demonstrate the need to understand fluid flow behavior in the convective channels of the rubblized shale bed as convective heating greatly decreases the time required to heat the oil shale to the production temperature when compared with conductive heating alone. We have developed and implemented a geometry creation strategy for a representative section of the EcoShale capsule, developed a meshing approach to deal with the complicated geometry and produce a well-behaved mesh, analyzed the effects of boundary conditions on the simulation results, and devised a new operator splitting solution algorithm that reduces computational costs by taking advantage of the differing convective and conductive time scales occurring in the simulation. These simulation tools can be applied to a wide range of processes involving convective fluid flow heating in rubblized beds.

Research investigations in oil shale, tar sand, coal research, advanced exploratory process technology, and advanced fuels research: Volume 1 -- Base program. Final report, October 1986--September 1993  

SciTech Connect

Numerous studies have been conducted in five principal areas: oil shale, tar sand, underground coal gasification, advanced process technology, and advanced fuels research. In subsequent years, underground coal gasification was broadened to be coal research, under which several research activities were conducted that related to coal processing. The most significant change occurred in 1989 when the agreement was redefined as a Base Program and a Jointly Sponsored Research Program (JSRP). Investigations were conducted under the Base Program to determine the physical and chemical properties of materials suitable for conversion to liquid and gaseous fuels, to test and evaluate processes and innovative concepts for such conversions, to monitor and determine environmental impacts related to development of commercial-sized operations, and to evaluate methods for mitigation of potential environmental impacts. This report is divided into two volumes: Volume 1 consists of 28 summaries that describe the principal research efforts conducted under the Base Program in five topic areas. Volume 2 describes tasks performed within the JSRP. Research conducted under this agreement has resulted in technology transfer of a variety of energy-related research information. A listing of related publications and presentations is given at the end of each research topic summary.

Sand consolidation method employing latex  

SciTech Connect

A method is described of treating a subterranean, unconsolidated sand and petroleum containing formation penetrated by at least one well, which is in fluid communication with at least a portion of the unconsolidated sand containing subterranean formation. This forms a flexible, permeable barrier around the well which restrains the movement of sand particles into the well while permitting the passage of formation fluids including petroleum there through. The method comprises: a. forming a predetermined quantity of a treating fluid comprising a water external phase emulsion having as its dispersed or discontinuous phase, a predetermined amount of an oil-insoluble rubber. The emulsion also contains a predetermined quantity of a material which hydrolyzes at reservoir temperature to form an acid; b. injecting the treating fluid into the formation to be consolidated; and c. leaving the fluid undisturbed in the formation for a predetermined period of time sufficient to allow the emulsion to break so the oil insoluble rubber coats the sand grains, forming a competent permeable barrier around the wellbore.

Oil shale of the Uinta Basin, northeastern Utah  

SciTech Connect

The Tertiary rocks, which occupy the interior of the Uinta basin, have been subdivided into four formations: Wasatch, Green River, Bridger, and Uinta. The division is based on stratigraphic and paleontologic evidence. Hydrocarbon materials have been found in all four formations, although bedded deposits (asphaltic sandstone and oil shale) are known only in the Wasatch and Green River. Veins of gilsonite, elaterite, ozocerite, and other related hydrocarbons cut all the Tertiary formation of the Uinta basin. Good oil shale (Uinta basin of Utah) is black or brownish black except on weathered surfaces, where it is blue-white or white. It is fine grained, slightly calcareous, and usually free from grit. It is tough and in thin-bedded deposits remarkably flexible. Although oil shale consists of thin laminae, this is not apparent in some specimens until after the rock has been heated and the oil driven off. Freshly broken oil shale gives off a peculiar odor similar to that of crude petroleum. Oil shale contains a large amount of carbonaceous matter (largely remains of lower plants, including algae), which is the source of the distillation products. Thin splinters of oil shale will burn with a very sooty flame and give off an asphaltic odor. Lean specimens of oil shale have a higher specific gravity than rich specimens and are generally heavier than coal.

Sand-control alternatives for horizontal wells  

SciTech Connect

This paper reports that it has been well documented that horizontal completions increase production rates, as much as two to five times those of conventional techniques, because more of the producing formation is exposed to the wellbore. Although productivity improvements are highly sensitive to reservoir parameters, it is becoming generally accepted that optimum horizontal lengths will be 2,000 to 4,000 ft. The length of these completions generally causes the velocity of the fluid at the sandface to be an order of magnitude less than that observed in conventional completions. Because drag forces contributed to sand production, horizontal wells can produce at higher sand-free flow rates than conventional completions in the same reservoir. While it is frequently argued that horizontal wells do not need sand control, the potential for sand production increases significantly as reserves deplete and rock stresses increase. This is becoming more evident today in several major North Sea oil fields with conventional completions. Also, many unconsolidated formations produce sand for the first time with the onset of water production, a typical problem in such areas as the Gulf of Mexico. Operators must decide whether to implement sand control in the original horizontal-completion program because of an immediate concern or because the potential exists for a problem to arise as the well matures.

Method and apparatus for hydrocarbon recovery from tar sands  

DOE Patents (OSTI)

A method and apparatus for utilizing tar sands having a broad range of bitumen content is disclosed. More particularly, tar sands are pyrolyzed in a cyclone retort with high temperature gases recycled from the cyclone retort to produce oil and hydrocarbon products. The spent tar sands are then burned at 2000.degree. F. in a burner to remove residual char and produce a solid waste that is easily disposable. The process and apparatus have the advantages of being able to utilize tar sands having a broad range of bitumen content and the advantage of producing product gases that are free from combustion gases and thereby have a higher heating value. Another important advantage is rapid pyrolysis of the tar sands in the cyclone so as to effectively utilize smaller sized reactor vessels for reducing capitol and operating costs.

Solvent extraction of Southern US tar sands  

SciTech Connect

The Department of Chemical Engineering at the University of Arkansas, in association with Diversified Petroleum Recovery, Inc. (DPR) of Little Rock, Arkansas, has been developing a solvent extraction process for the recovery of bitumen from tar sands for the past five years. The unique feature of the process is that the bitumen is recovered from the solvent by contacting with a co-solvent, which causes the bitumen to precipitate. The overall purpose of this project is to study both the technical and economic feasibility of applying this technology for recovery of bitumen from tar sands by (1) investigating the socioeconmic factors which affect (a) plant siting and (b) the market value of recovered bitumen; (2) operating a process demonstration unit at the rate of 1 lb/hr recovered bitumen while producing clean sand and recyclable solvents; and (3) determine the economic conditions which will make a bitumen recovery project economical. DPR has analyzed the historical trends of domestic production, consumption, discoveries and reserves of crude oil. They have started an investigation of the volatility in the price of crude oil and of gasoline prices and of the differential between gasoline and crude oil. DPR continues to analyze the geographical movement and demand for asphalt products. Utah does not appear economically attractive as a site for a bitumen from tar sands asphalt plant. Oklahoma sites are now being studied. This report also contains the quarterly progress report from a University of Nevada study to determine bitumen composition, oxygen uptake rates, and viscosities of Alabama and Utah bitumens. Both reports have been indexed separately for inclusion on the data base.

Cleaning oil contaminated beaches with chemicals  

SciTech Connect

Oil-dispersing chemicals were treated for cleaning persistent-type crude oil from experimentally contaminated New Jersey coastal beaches and were found to be generally ineffective. Although they completely cleaned the surface of the oiled sand, they removed little of the total oil. Instead they caused the oil to penetrate more deeply into the underlying sand, thereby compounding the pollution problem by expanding the zone of pollution, complicating any subsequent mechanical removal and, possibly, causing the oil to persist longer. Chemical treatment failed to induce quicksand or cause perceptible erosion of beach sand. A decrease in the cohesiveness of the sand was observed, but this also occurred in the presence of oil alone and could not be attributed to the presence of chemical.

Utah Heavy Oil Program  

Science Conference Proceedings (OSTI)

The Utah Heavy Oil Program (UHOP) was established in June 2006 to provide multidisciplinary research support to federal and state constituents for addressing the wide-ranging issues surrounding the creation of an industry for unconventional oil production in the United States. Additionally, UHOP was to serve as an on-going source of unbiased information to the nation surrounding technical, economic, legal and environmental aspects of developing heavy oil, oil sands, and oil shale resources. UHOP fulGilled its role by completing three tasks. First, in response to the Energy Policy Act of 2005 Section 369(p), UHOP published an update report to the 1987 technical and economic assessment of domestic heavy oil resources that was prepared by the Interstate Oil and Gas Compact Commission. The UHOP report, entitled 'A Technical, Economic, and Legal Assessment of North American Heavy Oil, Oil Sands, and Oil Shale Resources' was published in electronic and hard copy form in October 2007. Second, UHOP developed of a comprehensive, publicly accessible online repository of unconventional oil resources in North America based on the DSpace software platform. An interactive map was also developed as a source of geospatial information and as a means to interact with the repository from a geospatial setting. All documents uploaded to the repository are fully searchable by author, title, and keywords. Third, UHOP sponsored Give research projects related to unconventional fuels development. Two projects looked at issues associated with oil shale production, including oil shale pyrolysis kinetics, resource heterogeneity, and reservoir simulation. One project evaluated in situ production from Utah oil sands. Another project focused on water availability and produced water treatments. The last project considered commercial oil shale leasing from a policy, environmental, and economic perspective.

PROCESSING OF MONAZITE SAND  

DOE Patents (OSTI)

A process for the recovery of thorium, uranium, and rare earths from monazite sands is presented. The sands are first digested and dissolved in concentrated NaOH, and the solution is then diluted causing precipitation of uranium, thorium and rare earth hydroxides. The precipitate is collected and dissolved in HCl, and the pH of this solution is adjusted to about 6, precipitating the hydroxides of thorium and uranium but leaving the rare earths in solution. The rare earths are then separated from the solution by precipitation at a still higher pH. The thorium and uranium containing precipitate is redissolved in HNO/sub 3/ and the two elements are separated by extraction into tributyl phosphate and back extraction with a weakly acidic solution to remove the thorium.

Sand consolidation method  

SciTech Connect

This patent describes a method of treating a subterranean, unconsolidated sand and petroleum-containing formation whose temperature is less than 200{degrees}F penetrated by at least one well, which is in fluid communication with at least a portion of the unconsolidated sand-containing subterranean formation, in order to form a permeable barrier in the treatment zone around the well which restrains the movement of sand particles into the well while permitting the passage of formation fluids including petroleum therethrough. It comprises introducing a non aqueous gas into the treatment zone of the formation to reduce the water content of the portion of the formation where the permeable barrier is to be formed to less than 5 percent by volume based on the volume of pore space to be treated; introducing an effective volume of treating fluid into the treatment zone, comprising a compound which is capable of being acid catalyzed to undergo condensation polymerization at formation temperatures, an anhydride of a strong acid, and a diluent for the polymerizable compound and the anhydride; and allowing the treating fluid to remain in the treatment zone for a period of time sufficient to ensure substantially complete polymerization.

Unconventional Oil and Gas Resources  

Science Conference Proceedings (OSTI)

World oil use is projected to grow to 98 million b/d in 2015 and 118 million b/d in 2030. Total world natural gas consumption is projected to rise to 134 Tcf in 2015 and 182 Tcf in 2030. In an era of declining production and increasing demand, economically producing oil and gas from unconventional sources is a key challenge to maintaining global economic growth. Some unconventional hydrocarbon sources are already being developed, including gas shales, tight gas sands, heavy oil, oil sands, and coal bed methane. Roughly 20 years ago, gas production from tight sands, shales, and coals was considered uneconomic. Today, these resources provide 25% of the U.S. gas supply and that number is likely to increase. Venezuela has over 300 billion barrels of unproven extra-heavy oil reserves which would give it the largest reserves of any country in the world. It is currently producing over 550,000 b/d of heavy oil. Unconventional oil is also being produced in Canada from the Athabasca oil sands. 1.6 trillion barrels of oil are locked in the sands of which 175 billion barrels are proven reserves that can be recovered using current technology. Production from 29 companies now operating there exceeds 1 million barrels per day. The report provides an overview of continuous petroleum sources and gives a concise overview of the current status of varying types of unconventional oil and gas resources. Topics covered in the report include: an overview of the history of Oil and Natural Gas; an analysis of the Oil and Natural Gas industries, including current and future production, consumption, and reserves; a detailed description of the different types of unconventional oil and gas resources; an analysis of the key business factors that are driving the increased interest in unconventional resources; an analysis of the barriers that are hindering the development of unconventional resources; profiles of key producing regions; and, profiles of key unconventional oil and gas producers.

METHOD OF PROCESSING MONAZITE SAND  

DOE Patents (OSTI)

A method is given for the pretreatment of monazite sand with sodium hydroxide. When momazite sand is reacted with sodium hydroxide, the thorium, uranium, and rare earths are converted to water-insoluble hydrous oxides; but in the case of uranium, the precipitate compound may at least partly consist of a slightly soluble uranate. According to the patent, monazite sand is treated with an excess of aqueous sodium hydroxide solution, and the insoluble compounds of thorium, uranium, and the rare earths are separated from the aqueous solution. This solution is then concentrated causing sodium phosphate to crystallize out. The crystals are removed from the remaining solution, and the solution is recycled for reaction with a mew supply of momazite sand.

Acoustic sand detector for fluid flowstreams  

DOE Patents (OSTI)

The particle volume and particle mass production rate of particulate solids entrained in fluid flowstreams such as formation sand or fracture proppant entrained in oil and gas production flowstreams is determined by a system having a metal probe interposed in a flow conduit for transmitting acoustic emissions created by particles impacting the probe to a sensor and signal processing circuit which produces discrete signals related to the impact of each of the particles striking the probe. The volume or mass flow rate of particulates is determined from making an initial particle size distribution and particle energy distribution and comparing the initial energy distribution and/or the initial size distribution with values related to the impact energies of a predetermined number of recorded impacts. The comparison is also used to recalibrate the system to compensate for changes in flow velocity.

Sand deformation concept for in-situ recovery of bitumen by cyclic steam injection  

SciTech Connect

Historically, a vertical or horizontal fracture is believed to be a main recovery mechanism for a cyclic steam injection process from the unconsolidated oil sands. Most of the current computer models for the process are based on the fracture concept. With the new postulated ''Sand Deformation Concept'' on the other hand, the injected fluid is able to penetrate the unconsolidated oil sand by creating microchannels. When the pore pressure is reduced during production, these secondary flow channels will totally or partially collapse. Condensed steam tends to sweep fluids where the bitumen had been heated and imparts mobility due to the injected hot fluid. Flow geometry of the new concept was fully investigated in this study. The physical differences between the sand deformation zone and the no-deformation zone were also investigated. The major differences zone were also investigated. The major differences between these two zones are a porosity change, a pressure level and energy and flow characteristics resulting from the existence of microchannels. All of these modifications were successfully incorporated into a conventional numerical thermal simulator. The new model provided an excellent match for all the field observations (steam injection pressure, oil-and-water production rates, fluid production temperature, downhole production pressure and the salinity changes) of a steam stimulated well in an unconsolidated oil sand. Conclusion from the study indicates that the most important phenomenon for in-situ recovery of bitumen is the one way valve effect of the microchannels which are opened during injection and closed during production.

Three-dimensional geometry of fluvial reservoir sands: steam-drive case study  

Science Conference Proceedings (OSTI)

The three-dimensional geometry of fluvial sands in South Belridge heavy oil field was investigated as part of an Enhanced Oil Recovery study. It was shown that only close-spaced well data are sufficient to define the sand-body geometries and heterogeneities of multichannelled fluvial systems. Reservoir flow-unit patterns cannot necessarily be correctly delineated by isolated vertical sequence analysis. Wireline logs from 19 wells and conventional cores from seven wells in a 10-ac (660 ft x 660 ft) pattern were correlated in detail, using additional input from sedimentology, steam-flow patterns, and reservoir flow-unit continuity.

Water issues associated with heavy oil production.  

Science Conference Proceedings (OSTI)

Crude oil occurs in many different forms throughout the world. An important characteristic of crude oil that affects the ease with which it can be produced is its density and viscosity. Lighter crude oil typically can be produced more easily and at lower cost than heavier crude oil. Historically, much of the nation's oil supply came from domestic or international light or medium crude oil sources. California's extensive heavy oil production for more than a century is a notable exception. Oil and gas companies are actively looking toward heavier crude oil sources to help meet demands and to take advantage of large heavy oil reserves located in North and South America. Heavy oil includes very viscous oil resources like those found in some fields in California and Venezuela, oil shale, and tar sands (called oil sands in Canada). These are described in more detail in the next chapter. Water is integrally associated with conventional oil production. Produced water is the largest byproduct associated with oil production. The cost of managing large volumes of produced water is an important component of the overall cost of producing oil. Most mature oil fields rely on injected water to maintain formation pressure during production. The processes involved with heavy oil production often require external water supplies for steam generation, washing, and other steps. While some heavy oil processes generate produced water, others generate different types of industrial wastewater. Management and disposition of the wastewater presents challenges and costs for the operators. This report describes water requirements relating to heavy oil production and potential sources for that water. The report also describes how water is used and the resulting water quality impacts associated with heavy oil production.

METHOD OF PROCESSING MONAZITE SAND  

DOE Patents (OSTI)

A process is described for recovering thorium, uranium, and rare earth values from monazite sand. The monazite sand is first digested with sulfuric acid and the resulting "monazite sulfate" solution is adjusted to a pH of between 0.4 and 3.0, and oxalate anions are added causing precipitation of the thorium and the rare earths as the oxalates. The oxalate precipitate is separated from the uranium containing supernatant solution, and is dried and calcined to the oxides. The thorium and rare earth oxides are then dissolved in nitric acid and the solution is contacted with tribntyl phosphate whereby an organic extract phase containing the cerium and thorium values is obtained, together with an aqueous raffinate containing the other rare earth values. The organic phase is then separated from the aqueous raffinate and the cerium and thorium are back extracted with an aqueous medium.

Improved core recovery in laminated sand and shale sequences  

SciTech Connect

Coring and core analysis are essential to the exploration, development, and production phases of the oil and gas industry. Large-diameter (4-in. (10-cm)) core provides engineers and geologists with direct means to measure physical properties of reservoir rocks at both the microscopic and macroscopic levels. This information provides engineers with clues to improve their understanding of the reservoir and prediction of its performance. If stored properly, core may assist in development of the reservoir many years after the well is drilled. In microlaminated reservoirs, laboratory core analysis is very important because of inherent limitations in wireline log resolution. In these cases, petrophysical information, such as saturation, porosity, and net feet of pay, cannot be calculated from wireline data. Instead, these data must be measured directly from core plugs in the laboratory. Historically, core recovery in these types of reservoirs has not been good (Fig. 1A) using methods designed for firmly consolidated formations. These methods did not achieve satisfactory recovery in unconsolidated sand interbedded with hard shale stringers for two reasons: unconsolidated sand was eroded by mechanical or hydraulic means and shale ''jammed'' in the core barrel, thereby preventing more core from entering. Changes in coring strategies and equipment have nearly eliminated recovery problems in unconsolidated sand while reducing jams in shale (Fig. 1B).

The introduction of the microchanneling phenomenon to cyclic steam stimulation and its application to the numerical simulator (sand deformation concept)  

SciTech Connect

Historically, a vertical or horizontal fracture is believed to be a main recovery mechanism for a cyclic steam-injection process in unconsolidated oil sands. Most current computer models for the process are based on the fracture concept. With the postulated sand deformation concept, on the other hand, the injected fluid is able to penetrate the unconsolidated oil sand by creating microchannels. When the pore pressure is reduced during production, these secondary flow channels will collapse totally or partially. Condensed steam tends to sweep fluids where the bitumen had been heated and imparts mobility as a result of the injected hot fluid. Flow geometry of the new concept is described in this paper. The physical differences between the sand deformation zone and the no-deformation zone are also investigated. The three major differences between these two zones are porosity change, pressure level, and energy and flow characteristics resulting from the existence of microchannels. All these modifications were incorporated successfully into a conventional numerical thermal simulator. The new model provided an excellent match for all the field observations (steam-injection pressure, oil-and-water production rates, fluid production temperature, downhole production pressure, and salinity changes) of a steam-stimulated well in an unconsolidated oil sand. The study indicates that the most important phenomenon for in-situ recovery of bitumen is the one-way-valve effect of the microchannels, which are opened during injection and closed during production.

Geology of the Tambaredjo oil field, Suriname  

SciTech Connect

After the initial discovery in the sixties of oil below the coastal plain of Suriname (S. America), the State Oil Company of Suriname started production of the unique Tambaredjo field in 1982. The heavy, biodegraded oil (14-16[degrees] API) is produced under compaction drive, from the Paleocene T-sand (average thickness 5 m) at a depth of about 300 m. More than 300 wells have been drilled in an area of about 200 km[sup 2]. High resolution seismics makes it possible to correlate units down to 2 m thick. This dense network of bore holes is very suitable for geological correlations and 3D modeling. The T-sand reservoir consists of angular, medium to coarse grained unconsolidated sands with interfingering clays and lignites. The sands are deposited on a well cemented erosional Cretaceous basement. The reservoir is sealed by locally continuous clays. The oil is trapped in structural highs created by syn-sedimentary rejuvenated basement faults. The depositional environment of the T-sand ranges from fluviatile to deltaic. Frequent avulsion and synsedimentary faulting created a highly compartmented reservoir. Although interconnectedness of the sand bodies is high, clay smears and silting out of the edges confine reservoir compartments. The best genetic sand units such as channel fills or mouth bar deposits hardly correlate over more than a few hundred meters. The Tambaredjo oil field offers an unique opportunity to study the detailed sedimentology and petroleum geology of a fluvio-deltaic transitional realm on the passive margin along the Guiana coast.

Coupling the Alkaline-Surfactant-Polymer Technology and The Gelation Technology to Maximize Oil Production  

SciTech Connect

Performance and produced polymer evaluation of four alkaline-surfactant-polymer projects concluded that only one of the projects could have benefited from combining the alkaline-surfactant-polymer and gelation technologies. Cambridge, the 1993 Daqing, Mellott Ranch, and the Wardlaw alkaline-surfacant-polymer floods were studied. An initial gel treatment followed by an alkaline-surfactant-polymer flood in the Wardlaw field would have been a benefit due to reduction of fracture flow. Numerical simulation demonstrated that reducing the permeability of a high permeability zone of a reservoir with gel improved both waterflood and alkaline-surfactant-polymer flood oil recovery. A Minnelusa reservoir with both A and B sand production was simulated. A and B sands are separated by a shale layer. A sand and B sand waterflood oil recovery was improved by 196,000 bbls or 3.3% OOIP when a gel was placed in the B sand. Alkaline-surfactant-polymer flood oil recovery improvement over a waterflood was 392,000 bbls or 6.5% OOIP. Placing a gel into the B sand prior to an alkaline-surfactant-polymer flood resulted in 989,000 bbl or 16.4% OOIP more oil than only water injection. A sand and B sand alkaline-surfactant-polymer flood oil recovery was improved by 596,000 bbls or 9.9% OOIP when a gel was placed in the B sand.

Western gas sands project status report  

SciTech Connect

The Western Gas Sands Project Plan, Project Implementation Plans and Project Plan Document FY 78 are in various stages of preparation. Information gathering by U.S. Geological Survey (USGS) of the initial data base for many of the project activities is nearing completion. Some base maps are complete and field investigations in the principal areas of interest are being conducted. Research and development by Energy Research Centers and National Laboratories were directed toward new tools and instrumentation systems, rock mechanics experiments, mathematical modeling, and data analysis. The Uinta Basin in Utah and Piceance Basin in Colorado have ongoing massive hydraulic fracture (MHF) experiments in the Upper Cretaceous tight gas formations. These are: CER Corporation, MHF 3; Gas Producing Enterprises, Natural Buttes No. 14, 18, 19, 20; Mobil Oil, F-31-13G; and Rio Blanco Natural Gas, 498-4-1. Colorado Interstate Gas Company has been awarded a contract to determine if productivity in low permeability reservoirs can be improved by reducing the interstitialwater saturation. They will be using two wells, the Sprague No. 1 and Miller No. 1, completed in the Dakota J formation in the Wattenberg Field in north central Colorado. All of the massive hydraulic fracture wells, with the exception of the Pacific Transmission well, have been fractured as planned. The Mobil and GPE No. 14, 18, and 20 wells show significant improvement as compared to original flow rates. The Mobil well is being tested for additional MHF treatments. Sandia Laboratories is continuing their research program in hydraulic fracturing at DOE's Nevada Test Site (NTS).

Crosshole EM for oil field characterization and EOR monitoring: Field examples from Lost Hills, California  

SciTech Connect

A steamflood recently initiated by Mobil Development and Production U.S. at the Lost Hills No 3 oil field in California is notable for its shallow depth and the application of electromagnetic (EM) geophysical techniques to monitor the subsurface steam flow. Steam was injected into three stacked eastward-dipping unconsolidated oil sands at depths from 60 to 120 m; the plume is expected to develop as an ellipsoid aligned with the regional northwest-southeast strike. Because of the shallow depth of the sands and the high viscosity of the heavy oil, it is important to track the steam in the unconsolidated sediments for both economic and safety reasons. Crosshole and surface-to-borehole electromagnetic imaging were applied for reservoir characterization and steamflood monitoring. The crosshole EM data were collected to map the interwell distribution of the high-resistivity oil sands and to track the injected steam and hot water. Measurements were made in two fiberglass-cased observation wells straddling the steam injector on a northeast-southwest profile. Field data were collected before the steam drive, to map the distribution of the oil sands, and then 6 and 10 months after steam was injected, to monitor the expansion of the steam chest. Resistivity images derived from the collected data clearly delineated the distribution and dipping structure of the target oil sands. Difference images from data collected before and during steamflooding indicate that the steam chest has developed only in the middle and lower oil sands, and it has preferentially migrated westward in the middle oil sand and eastward in the deeper sand. Surface-to-borehole field data sets at Lost Hills were responsive to the large-scale subsurface structure but insufficiently sensitive to model steam chest development in the middle and lower oil sands. As the steam chest develops further, these data will be of more use for process monitoring.

CAVITY LIKE COMPLETIONS IN WEAK SANDS PREFERRED UPSTREAM MANAGEMENT PRACTICES  

SciTech Connect

The technology referred to as Cavity Like Completions (CLC) offers a new technique to complete wells in friable and unconsolidated sands. A successfully designed CLC provides significant increases in well PI (performance index) at lower costs than alternative completion techniques. CLC technology is being developed and documented by a partnership of major oil and gas companies through a GPRI (Global Petroleum Research Institute) joint venture. Through the DOE-funded PUMP program, the experiences of the members of the joint venture will be described for other oil and gas producing companies. To date six examples of CLC completions have been investigated by the JV. The project was performed to introduce a new type of completion (or recompletion) technique to the industry that, in many cases, offers a more cost effective method to produce oil and gas from friable reservoirs. The project's scope of work included: (1) Further develop theory, laboratory and field data into a unified model to predict performance of cavity completion; (2) Perform at least one well test for cavity completion (well provided by one of the sponsor companies); (3) Provide summary of geo-mechanical models for PI increase; and (4) Develop guidelines to evaluate success of potential cavity completion. The project tracks the experiences of a joint industry consortium (GPRI No. 17) over a three year period and compiles results of the activities of this group.

Completion methods in thick, multilayered tight gas sands  

E-Print Network (OSTI)

Tight gas sands, coal-bed methane, and gas shales are commonly called unconventional reservoirs. Tight gas sands (TGS) are often described as formations with an expected average permeability of 0.1mD or less. Gas production rates from TGS reservoirs are usually low due to poor permeability. As such, state-of-the-art technology must be used to economically develop the resource. TGS formations need to be hydraulically fractured in order to enhance the gas production rates. A majority of these reservoirs can be described as thick, multilayered gas systems. Many reservoirs are hundreds of feet thick and some are thousands of feet thick. The technology used to complete and stimulate thick, tight gas reservoirs is quite complex. It is often difficult to determine the optimum completion and stimulating techniques in thick reservoirs. The optimum methods are functions of many parameters, such as depth, pressure, temperature, in-situ stress and the number of layers. In multilayered reservoirs, it is important to include several sand layers in a single completion. The petroleum literature contains information on the various diversion techniques involved in the completion of these multilayered reservoirs. In this research, we have deduced and evaluated eight possible techniques that have been used in the oil and gas industry to divert multilayered fracture treatments in layered reservoirs. We have developed decision charts, economic analyses and computer programs that will assist completion engineers in determining which of the diversion methods are feasible for a given well stimulation. Our computer programs have been tested using case histories from the petroleum literature with results expressed in this thesis. A limited entry design program has also being developed from this research to calculate the fluid distribution into different layers when fracture treating multilayered tight gas reservoirs using the limited entry technique. The research is aimed at providing decision tools which will eventually be input into an expert advisor for well completions in tight gas reservoirs worldwide.

New method for sand control and well stimulation in unconsolidated dirty sands  

SciTech Connect

A new technique, the Solder Glass sand consolidation well completion method, has been developed which allows unlimited drawdown and improves productivity in wells completed in unconsolidated formations containing shales and clays. This technique eliminates the problems of sand production and fines migration by artificially consolidating a volume of reservoir sand near the wellbore. The consolidation is resistant to high temperature, chemical attack, and degradation resulting from high velocity fluid flow. Additionally, porosity and permeability in the consolidated volume of reservoir sand are improved as a result of irreversible dehydration of clays. 12 refs.

After the fire is out: A post in-situ combustion audit, Upper Miocene deepwater sands, San Joaquin Valley, California  

SciTech Connect

An audit of small-scale, air in-situ combustion projects developed in the upper Miocene Monarch and Webster unconsolidated, arkosic sand reservoirs, Midway Sunset field, Kern County, California, demonstrates minor rock diagenesis. Burn distribution and progression is controlled by reservoir continuity, layering, and original permeability variations. Air in-situ combustion projects were operated between 1962 and 1976. Injected air drives a burning oil (coke) front through a reservoir reaching maximum temperatures of 650C. Dense new well control including 3,000 ft of core is part of a large steamdrive development. Fireflood-induced diagenesis was clearly visible in core. Altered zones include sands with reduced oil saturations, burn zones with remaining coke, and reddish (oxidized) zones with no hydrocarbons. Wireline log response in these zones have been highly modified. Detailed mapping by subzone using pre- and post-burn logs permits the determination of three-dimensional burn and reduced saturation geometries. Little rock alteration occurred in these sands. The only diagenesis of the sand fraction was to calcite grains, where oil/calcite reactions produced calcium sulfate rims and CO{sub 2} gas. X-ray diffraction of finer 'matrix' reveals no recrystallization of opal-CT, no irreversible collapse of smectite, and only minor removal of kaolinite. Partial dissolution of opal and zeolites was visible in SEM. This nonequilibrium mineral suite probably reflects kinetic control by grain size, protective grain coatings, and alteration time.

Frame moduli of unconsolidated sands and sandstones  

SciTech Connect

In this study, the authors investigate the elastic moduli of the empty grain framework (the frame moduli) in unconsolidated sands and consolidated sandstones. The work was done to improve the interpretation of seismic amplitude anomalies and amplitude variations with offset (AVO) associated with hydrocarbon reservoirs. They developed a laboratory apparatus to measure the frame Poisson's ratio and Young's modulus of unconsolidated sands at seismic frequencies (0.2 to 155 Hz) in samples approximately 11 cm long. They used ultrasonic pulse velocity measurements to measure the frame moduli of consolidated sandstones. They found that the correlation coefficient between the frame Poisson's ratio [sigma][sub A] and the mineral Poisson's ratio [sigma][sub M] is 0.84 in consolidated sandstones and only 0.28 in unconsolidated sands. The range of [sigma][sub A] values in unconsolidated sands is 0.115 to 0.237 (mean = 0.187, standard deviation = 0.030), and [sigma][sub A] cannot be estimated without core or log analyses. Frame moduli analyses of core samples can be used to calibrate the interpretation of seismic amplitude anomalies and AVO effects. For use in areas without core or log analyses, the authors developed an empirical relation that can be used to estimate [sigma][sub A] in unconsolidated sands and sandstones from [sigma][sub M] and the frame P-wave modulus.

Reservoir characterization of the upper Merecure and lower Oficina Formations sands in the Leona Este Field, Eastern Venezuela Basin  

E-Print Network (OSTI)

The "S5", "T" and "U1" sands, traditionally described as part of the lower section of the "Oficina" Formation, and the "U2" sand, as part of the upper interval of the "Merecure" Formation, contain the largest oil remaining reserves of the Leona Este Field, which is located in the southern portion of the Eastern Venezuela Basin. Two or more of these reservoir sands, which are interbedded with shales, have been simultaneously produced pursuing an increase in the oil production rate, but an unexpected production performance was obtained: the accelerated and early increase of the water volume associated to the produced oil has caused the shut down of some wells in the Leona Este Field. In order to understand this productive performance and to re-evaluate the hydrocarbon potential of the study interval, it is important to describe these reservoirs in terms of their depositional origin and trap formation. An integrated reservoir model was constructed using all the available geological, geophysical and production data. The hydrocarbon trapping mechanism of each studied stratigraphic interval, traditionally known as the "S5", "TU", "TL", "U1U", "U1L", "U2U", "U2MA", "U2MB" and "U2L" sands, includes two components: ? Stratigraphic component: each stratigraphic interval presents one or more reservoir zones composed by sandy deposits that fill belts of stacked tidal-fluvial channels in a SSE-NNW trending tide-dominated estuarine system. In most intervals, these contemporaneous-in-deposition reservoir zones are not connected due to the lateral variation of facies present in the tide-dominated estuary. ? Structural component: northward dipping strata have been offset by a W-E trending major normal fault and secondary normal faults striking parallel to the major one. The major fault is the southern seal of the hydrocarbon traps. The most important prospects of the study interval are the reservoir zones 1 and 2 of the "U1L" sand, the reservoir zone 3 of the "U2MB" sand, and the "U1U" sand, which show more than 15 feet of average net sand thickness, and contain the largest volume of recoverable oil per reservoir zone in the Leona Este Field.

Sand control method employing special hydraulic fracturing technique  

SciTech Connect

A novel sand control method is disclosed wherein high viscosity, high sand concentration, fracturing fluids are pumped through sets of vertically oriented perforations in borehole casings located in unconsolidated or loosely consolidated pay zones. Various techniques are utilized to insure that sand fills disposed on either side of the borehole casing cover and substantially overlap each borehole casing perforation set. Procedures are then followed to bring the well into production without washing out the sand fills in these areas, whereby the resulting perforation-sand fill configurations effectively control sand production from the treated zone.

Heading off the permanent oil crisis  

SciTech Connect

The 1996 spike in gasoline prices was not a signal of any fundamental worldwide shortage of crude oil. But based on a review of many studies of recoverable crude oil that have been published since the 1950s, it looks as though such a shortfall is now within sight. With world demand for oil growing at 2 percent per year, global production is likely to peak between the years 2007 and 2014. As this time approaches, we can expect prices to rise markedly and, most likely, permanently. Policy changes are needed now to ease the transition to high-priced oil. Oil production will continue, though at a declining rate, for many decades after its peak, and there are enormous amounts of coal, oil sands, heavy oil, and oil shales worldwide that could be used to produce liquid or gaseous substitutes for crude oil, albeit at higher prices. But the facilities for making such synthetic fuels are costly to build and environmentally damaging to operate, and their use would substantially increase carbon dioxide emissions (compared to emissions from products made from conventional crude oil). This paper examines ways of heading of the impending oil crisis. 8 refs., 3 figs.

Mechanisms of oil displacement by microorganisms  

SciTech Connect

Mechanisms of oil displacement at the oil-brine-sand interfaces by bacteria were investigated by microscopic observations and capillary pressure changes using unconsolidated, thin, reservoir flow cells. Three genera of bacteria, Bacillus, Pseudomonas, and Clostridium, were injected into water-wet and oil-wet cells of unconsolidated sand, saturated with brine and crude oil. The flow cells were placed under a microscope for visual and photographic observations. The flow cells were connected to a manometer to examine the complete capillary pressure hysteresis loop before and after introduction of bacteria. The thin reservoir flow cells were first saturated with brine, and then displaced to irreducible water saturation with crude oil. Oil and brine displacements were then made to determine the complete capillary pressure relationship. Next, the bacteria and nutrients were introduced and incubated in the flow cell for 24-48 hours. Microscopic observations were recorded photographically. After incubation, oil and brine displacements were again made to determine the capillary pressure hysteresis loop.

E-Print Network (OSTI)

Oil-pollution due to accidental during transportation or leakage from storage not only brings large damage to the environments, but it also affects the geotechnical properties of soil. Hence, an extensive laboratory testing program was carried out to investigate the geotechnical properties on palm biodiesel contaminated weathered granite soil and mining sand. A series of laboratory experiments has been carried out by using a direct simple shear device on clean and contaminated soil samples. The contaminated soil samples were mixed with palm biodiesel in the amount 5%, 10 % and 15 % by dry weight. The objective of this study is to determine the effects of palm biodiesel contamination on the mining sand and weathered granite soil samples. The overall results indicated decrease of shear strength with increasing palm biodiesel contents.

Various techniques involving microwave, acoustic, thermal and magnetic sensors have been used to detect such objects. Acoustic and microwave sensors have shown promise, especially if used together. In most cases, the sensor package is scanned over an area to eventually build up an image or map of anomalies. We are proposing an alternate, acoustic method that directly provides an image of acoustic waves in sand or soil, and their interaction with buried objects. The INEEL Laser Ultrasonic Camera utilizes dynamic holography within photorefractive recording materials. This permits one to image and demodulate acoustic waves on surfaces in real time, without scanning. A video image is produced where intensity is directly and linearly proportional to surface motion. Both specular and diffusely reflecting surfaces can be accomodated and surface motion as small as 0.1 nm can be quantitatively detected. This system was used to directly image acoustic surface waves in sand as well as in solid objects. Waves as frequencies of 16 kHz were generated using modified acoustic speakers. These waves were directed through sand toward partially buried objects. The sand container was not on a vibration isolation table, but sat on the lab floor. Interaction of wavefronts with buried objects showed reflection, diffraction and interference effects that could provide clues to location and characteristics of buried objects. Although results are preliminary, success in this effort suggests that this method could be applied to detection of buried landmines or other near-surface items such as pipes and tanks.

Conjunctive Surface and Groundwater Management in Utah: Implications for Oil Shale and Oil Sands Development  

Science Conference Proceedings (OSTI)

Unconventional fuel development will require scarce water resources. In an environment characterized by scarcity, and where most water resources are fully allocated, prospective development will require minimizing water use and seeking to use water resources in the most efficient manner. Conjunctive use of surface and groundwater provides just such an opportunity. Conjunctive use includes two main practices: First, integrating surface water diversions and groundwater withdrawals to maximize efficiency and minimize impacts on other resource users and ecological processes. Second, conjunctive use includes capturing surplus or unused surface water and injecting or infiltrating that water into groundwater aquifers in order to increase recharge rates. Conjunctive management holds promise as a means of addressing some of the West's most intractable problems. Conjunctive management can firm up water supplies by more effectively capturing spring runoff and surplus water, and by integrating its use with groundwater withdrawals; surface and groundwater use can be further integrated with managed aquifer recharge projects. Such integration can maximize water storage and availability, while simultaneously minimizing evaporative loss, reservoir sedimentation, and surface use impacts. Any of these impacts, if left unresolved, could derail commercial-scale unconventional fuel development. Unconventional fuel developers could therefore benefit from incorporating conjunctive use into their development plans. Despite its advantages, conjunctive use is not a panacea. Conjunctive use means using resources in harmony to maximize and stabilize long-term supplies â?? it does not mean maximizing the use of two separate but interrelated resources for unsustainable short-term gains â?? and it cannot resolve all problems or provide water where no unappropriated water exists. Moreover, conjunctive use may pose risks to ecological values forgone when water that would otherwise remain in a stream is diverted for aquifer recharge or other uses. To better understand the rapidly evolving field of conjunctive use, this Topical Report begins with a discussion of Utah water law, with an emphasis on conjunctive use issues. We contrast Utahâ??s approach with efforts undertaken in neighboring states and by the federal government. We then relate conjunctive use to the unconventional fuel industry and discuss how conjunctive use can help address pressing challenges. While conjunctive management cannot create water where none exists, it does hold promise to manage existing resources in a more efficient manner. Moreover, conjunctive management reflects an important trend in western water law that could provide benefit to those contemplating activities that require large-scale water development.

Chemical Methods for Ugnu Viscous Oils  

SciTech Connect

The North Slope of Alaska has large (about 20 billion barrels) deposits of viscous oil in Ugnu, West Sak and Shraeder Bluff reservoirs. These shallow reservoirs overlie existing productive reservoirs such as Kuparuk and Milne Point. The viscosity of the Ugnu reservoir on top of Milne Point varies from 200 cp to 10,000 cp and the depth is about 3300 ft. The same reservoir extends to the west on the top of the Kuparuk River Unit and onto the Beaufort Sea. The depth of the reservoir decreases and the viscosity increases towards the west. Currently, the operators are testing cold heavy oil production with sand (CHOPS) in Ugnu, but oil recovery is expected to be low (< 10%). Improved oil recovery techniques must be developed for these reservoirs. The proximity to the permafrost is an issue for thermal methods; thus nonthermal methods must be considered. The objective of this project is to develop chemical methods for the Ugnu reservoir on the top of Milne Point. An alkaline-surfactant-polymer (ASP) formulation was developed for a viscous oil (330 cp) where as an alkaline-surfactant formulation was developed for a heavy oil (10,000 cp). These formulations were tested in one-dimensional and quarter five-spot Ugnu sand packs. Micromodel studies were conducted to determine the mechanisms of high viscosity ratio displacements. Laboratory displacements were modeled and transport parameters (such as relative permeability) were determined that can be used in reservoir simulations. Ugnu oil is suitable for chemical flooding because it is biodegraded and contains some organic acids. The acids react with injected alkali to produce soap. This soap helps in lowering interfacial tension between water and oil which in turn helps in the formation of macro and micro emulsions. A lower amount of synthetic surfactant is needed because of the presence of organic acids in the oil. Tertiary ASP flooding is very effective for the 330 cp viscous oil in 1D sand pack. This chemical formulation includes 1.5% of an alkali, 0.4% of a nonionic surfactant, and 0.48% of a polymer. The secondary waterflood in a 1D sand pack had a cumulative recovery of 0.61 PV in about 3 PV injection. The residual oil saturation to waterflood was 0.26. Injection of tertiary alkaline-surfactant-polymer slug followed by tapered polymer slugs could recover almost 100% of the remaining oil. The tertiary alkali-surfactant-polymer flood of the 330 cp oil is stable in three-dimensions; it was verified by a flood in a transparent 5-spot model. A secondary polymer flood is also effective for the 330 cp viscous oil in 1D sand pack. The secondary polymer flood recovered about 0.78 PV of oil in about 1 PV injection. The remaining oil saturation was 0.09. The pressure drops were reasonable (<2 psi/ft) and depended mainly on the viscosity of the polymer slug injected. For the heavy crude oil (of viscosity 10,000 cp), low viscosity (10-100 cp) oil-in-water emulsions can be obtained at salinity up to 20,000 ppm by using a hydrophilic surfactant along with an alkali at a high water-to-oil ratio of 9:1. Very dilute surfactant concentrations (~0.1 wt%) of the synthetic surfactant are required to generate the emulsions. It is much easier to flow the low viscosity emulsion than the original oil of viscosity 10,000 cp. Decreasing the WOR reverses the type of emulsion to water-in-oil type. For a low salinity of 0 ppm NaCl, the emulsion remained O/W even when the WOR was decreased. Hence a low salinity injection water is preferred if an oil-in-water emulsion is to be formed. Secondary waterflood of the 10,000 cp heavy oil followed by tertiary injection of alkaline-surfactants is very effective. Waterflood has early water breakthrough, but recovers a substantial amount of oil beyond breakthrough. Waterflood recovers 20-37% PV of the oil in 1D sand pack in about 3 PV injection. Tertiary alkali-surfactant injection increases the heavy oil recovery to 50-70% PV in 1D sand packs. As the salinity increased, the oil recovery due to alkaline surfactant flood increased, but water-in-oil emulsion was p

Well completion process for formations with unconsolidated sands  

DOE Patents (OSTI)

A method for consolidating sand around a well, involving injecting hot water or steam through well casing perforations in to create a cement-like area around the perforation of sufficient rigidity to prevent sand from flowing into and obstructing the well. The cement area has several wormholes that provide fluid passageways between the well and the formation, while still inhibiting sand inflow.

Effects of Sand on the Components and Performance of Electric Submersible Pumps  

E-Print Network (OSTI)

The increasing world demand for oil has pushed oil companies to extract it from the ocean at extreme depths. With the increase in depth comes an increase in operation costs, especially the deep-sea equipment changeover cost. To be able to push the oil to the ocean surface, Electrical Submersible Pumps (ESPs) are commonly used as artificial lift. The changeover cost of these pumps in deep-water has been estimated to sometimes be as much as forty times the cost of a new pump. One common reason for the failure of ESPs is the erosion and abrasion created by the fine sands that seep through the gravel pack mesh in the well hole. These fine sand particles are most destructive to the bearings and bushings due to their capability to enter the clearances lubricated by the pumped fluid. Over time, the sustained abrasion and erosion in the different components of the ESP will affect the performance of the pump and could lead to its damage. This work describes the design, construction and evaluation of an erosion test rig built at the facilities of the Turbomachinery Laboratory in Texas A&M University. The test rig is capable of introducing 100 mesh (6 mil) sand into the flow loop, measure its concentration and separate it at the exit with minimal water loss. The pump under study is a Baker Hughes 10.25" WJE1000. The performance of the pump is described by measuring the head, flow rate, power and efficiency. The pump is equipped with accelerometers to detect the casing vibration as well as proximity probes in five locations along the pump to detect the internal vibrations of the shaft near the bearings as well as impeller radial movement. The baseline data, to be used for comparison with the worn out pump, has been shown and recommendations for the study method and operation of the rig are given.

High efficiency shale oil recovery  

SciTech Connect

The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated at bench-scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although a batch oil shale sample will be sealed in the batch kiln from the start until the end of the run, the process conditions for the batch will be the same as the conditions that an element of oil shale would encounter in a large continuous process kiln. For example, similar conditions of heat-up rate (20 deg F/min during the pyrolysis), oxidation of the residue and cool-down will prevail for the element in both systems. This batch kiln is a unit constructed in a 1987 Phase I SBIR tar sand retorting project. The kiln worked fairly well in that project; however, the need for certain modifications was observed. These modifications are now underway to simplify the operation and make the data and analysis more exact. The agenda for the first three months of the project consisted of the first of nine tasks and was specified as the following four items: 1. Sample acquisition and equipment alteration: Obtain seven oil shale samples, of varying grade each 10 lb or more, and samples of quartz sand. Order equipment for kiln modification. 3. Set up and modify kiln for operation, including electric heaters on the ends of the kiln. 4. Connect data logger and make other repairs and changes in rotary batch kiln.

Western gas sands: Technology status report  

Science Conference Proceedings (OSTI)

Research on western gas sands is conducted by the US Department of Energy's Morgantown Technology Center to encourage the development of very low permeability gas sands in the western United States. The current search is an outgrowth of earlier Government research on tight sands in which nuclear and massive hydraulics fracturing stimulations were tested without definitive results. Based on input from the gas industry, universities, and geologic and engineering consulting firms, activites were broadened to include fundamental research and development. Consequently, the focus of the research for the last several years has been on improving diagnostic instruments for evaluating reservoir and stimulation performances, interpreting geophysical and engineering data, and stimulation techniques. Intergrated geologic studies of three depositional basins that contain tight lenticular sandstone units have also been pursued as part of this new effort. To date, the following tentative conclusions have been formulated: The permeability of the tight gas sands can be as much as three to four orders of magnitude lower than that of conventional gas deposits. Nineteen western geologic basins and trends have been identified that contain significant volumes of tight gas. Gas resources in the priority geologic basins have been estimated as follows: Piceance Basin, 420 Tcf.; Greater Green River Basin, 4971 Tcf.; and Uinta Basin, 21 Tcf. The critical parameters for successfully developing tight sandstone resources are the presence of natural fractures within a reservoir and the effective propped length of hydraulically induced fractures. Stimulation technology is presently insufficient to efficiently recover gas from lenticular, tight reservoirs. 15 refs., 14 figs., 3 tabs.

Crosshole EM for oil field characterization and EOR monitoring: Field examples  

SciTech Connect

Crosshole and surface-to-borehole electromagnetic (EM) imaging is applied to reservoir characterization and steam flood monitoring in a central California oil field. Steam was injected into three stacked, eastward-dipping, unconsolidated oil sands within the upper 200 in. The steam plume is expected to develop as an ellipse aligned with the regional northwest-southeast strike. EM measurements were made from two flberglass-cased observation wells straddling the steam injector on a northeast-southwest profile. Field data were collected before the initiation of a steam drive to map the distribution of the oil sands and then six months after the steam was injected to monitor the progress of the steam chest. Resisitivity images derived from the EM data collected before steam injection clearly delineate the distribution and dipping structure on the target oil sands. Difference images from data collected before and after steam flooding indicate that the steam chest has developed only in the deeper oil sands, and it has preferentially migrated eastward. Surface-to-borehole measurements were useful in mapping the distribution of the major oil sands, but they were insensitive to resisitivity changes in the early stages of the steam flood.

Western oil shale conversion using the ROPE copyright process  

DOE Green Energy (OSTI)

Western Research Institute (WRI) is continuing to develop the Recycle Oil Pyrolysis and Extraction (ROPE) process to recover liquid hydrocarbon products from oil shale, tar sand, and other solid hydrocarbonaceous materials. The process consists of three major steps: (1) pyrolyzing the hydrocarbonaceous material at a low temperature (T {le} 400{degrees}C) with recycled product oil, (2) completing the pyrolysis of the residue at a higher temperature (T > 400{degrees}C) in the absence of product oil, and (3) combusting the solid residue and pyrolysis gas in an inclined fluidized-bed reactor to produce process heat. Many conventional processes, such as the Paraho and Union processes, do not use oil shale fines (particles smaller than 1.27 cm in diameter). The amount of shale discarded as fines from these processes can be as high as 20% of the total oil shale mined. Research conducted to date suggests that the ROPE process can significantly improve the overall oil recovery from western oil shale by processing the oil shale fines typically discarded by conventional processes. Also, if the oil shale fines are co-processed with shale oil used as the heavy recycle oil, a better quality oil will be produced that can be blended with the original shale oil to make an overall produce that is more acceptable to the refineries and easier to pipeline. Results from tests conducted in a 2-inch process development unit (PDU) and a 6-inch bench-scale unit (BSU) with western oil shale demonstrated a maximum oil yield at temperatures between 700 and 750{degrees}F (371 and 399{degrees}C). Test results also suggest that the ROPE process has a strong potential for recovering oil from oil shale fines, upgrading shale oil, and separating high-nitrogen-content oil for use as an asphalt additive. 6 refs., 10 figs., 11 tabs.

Field development options for a waterflooded heavy-oil reservoir  

Science Conference Proceedings (OSTI)

Battrum Unit 4 is a moderately heavy-oil reservoir in Saskatchewan producing under waterflood from a thin sand. This paper describes a history match of previous field behavior and systematically analyzes through the use of numerical simulation the potential benefits to production of further waterflooding (with and without infill drilling), steamflooding, and horizontal drilling. It is found that the remaining oil recovery potential of a steamflood with horizontal well is significantly higher than that of any of the waterflood options.

Oil reserves  

SciTech Connect

As of March 1988, the Strategic Petroleum Reserve inventory totaled 544.9 million barrels of oil. During the past 6 months the Department of Energy added 11.0 million barrels of crude oil to the SPR. During this period, DOE distributed $208 million from the SPR Petroleum Account. All of the oil was purchased from PEMEX--the Mexican national oil company. In FY 1988, $164 million was appropriated for facilities development and management and $439 million for oil purchases. For FY 1989, DOE proposes to obligate $173 million for facilities development and management and $236 million for oil purchases. DOE plans to postpone all further drawdown exercises involving crude oil movements until their effects on cavern integrity are evaluated. DOE and the Military Sealift Command have made progress in resolving the questions surrounding nearly $500,000 in payments for demurrage charges.

Unconsolidated sand grain shape, size impact frac-pack design  

SciTech Connect

The shape and size of sand grains, as well as the saturating fluid, influence the mechanical properties of unconsolidated sands and need to be considered in frac-pack design. These mechanical properties of unconsolidated properties of unconsolidated sands play an important role in determining the geometry of frac-pack treatments. Stress-strain curves obtained for unconsolidated sands at elevated stresses show highly nonlinear hysteretic behavior. The impact of these findings on frac-pack design can be significant. The nonlinear elastic properties of unconsolidated sand can give rise to some unique features in the pressure response and in the fracture geometry that may not be observed in hard rocks. This article focuses on the impact of mechanical properties of poorly consolidated and unconsolidated sands on the geometry of frac packs. The paper discusses frac packs, mechanical properties (Young`s modulus, shear failure) and effective treatments.

Have We Run Out of Oil Yet? Oil Peaking Analysis from an Optimist's Perspective  

Science Conference Proceedings (OSTI)

This study addresses several questions concerning the peaking of conventional oil production from an optimist's perspective. Is the oil peak imminent? What is the range of uncertainty? What are the key determining factors? Will a transition to unconventional oil undermine or strengthen OPEC's influence over world oil markets? These issues are explored using a model combining alternative world energy scenarios with an accounting of resource depletion and a market-based simulation of transition to unconventional oil resources. No political or environmental constraints are allowed to hinder oil production, geological constraints on the rates at which oil can be produced are not represented, and when USGS resource estimates are used, more than the mean estimate of ultimately recoverable resources is assumed to exist. The issue is framed not as a question of "running out" of conventional oil, but in terms of the timing and rate of transition from conventional to unconventional oil resources. Unconventional oil is chosen because production from Venezuela's heavy-oil fields and Canada's Athabascan oil sands is already underway on a significant scale and unconventional oil is most consistent with the existing infrastructure for producing, refining, distributing and consuming petroleum. However, natural gas or even coal might also prove to be economical sources of liquid hydrocarbon fuels. These results indicate a high probability that production of conventional oil from outside of the Middle East region will peak, or that the rate of increase of production will become highly constrained before 2025. If world consumption of hydrocarbon fuels is to continue growing, massive development of unconventional resources will be required. While there are grounds for pessimism and optimism, it is certainly not too soon for extensive, detailed analysis of transitions to alternative energy sources.

Flotation behavior of digested asphalt ridge tar sands  

SciTech Connect

The hot water process for Utah tar sands differs from that used for Canadian tar sands due to inherent differences in respective bitumen viscosities and the nature of bitumen-sand association. Although contact angle measurements of solvent extracted Asphalt Ridge bitumen indicated moderate hydrophobicity, air bubble attachment to the bitumen concentrate is not possible. This suggests that flotation separation is dependent on air bubble entrapment. Improved separation at higher flotation temperatures was due to the decrease in bitumen viscosity. 16 refs.

TESTING OF TMR SAND MANTIS FINAL REPORT  

SciTech Connect

Screening tests of Sand Mantis candidate materials selected for erosion resistance have been completed. The results of this testing identified that over a relatively short period of operation (<1 hour), measurable erosion will occur in each of the candidate zoom tube materials given equal operating exposure. Additionally, this testing has shown that erosion of the rubber discharge hose directly downstream of the vehicle could be expected to limit the service life of the discharge hose. On the basis of these test results, SRNL recommends the following; {lg_bullet} redesign of critical system components (e.g., zoom tube, discharge hose) should be conducted to improve system characteristics relative to erosion and capitalize on the results of this testing, {lg_bullet} continued efforts to deploy the Sand Mantis should include testing to better define and optimize operating parameters, and gain an understanding of system dynamics, {lg_bullet} discontinue wear testing with the selected materials pending redesign of critical system components (1st recommendation) and inclusion of other candidate materials. The final selection of additional candidate materials should be made following design changes, but might include a Stellite alloy or zirconia.

Running Out of and Into Oil: Analyzing Global Oil Depletion and Transition Through 2050  

DOE Green Energy (OSTI)

This report presents a risk analysis of world conventional oil resource production, depletion, expansion, and a possible transition to unconventional oil resources such as oil sands, heavy oil and shale oil over the period 2000 to 2050. Risk analysis uses Monte Carlo simulation methods to produce a probability distribution of outcomes rather than a single value. Probability distributions are produced for the year in which conventional oil production peaks for the world as a whole and the year of peak production from regions outside the Middle East. Recent estimates of world oil resources by the United States Geological Survey (USGS), the International Institute of Applied Systems Analysis (IIASA), the World Energy Council (WEC) and Dr. C. Campbell provide alternative views of the extent of ultimate world oil resources. A model of oil resource depletion and expansion for twelve world regions is combined with a market equilibrium model of conventional and unconventional oil supply and demand to create a World Energy Scenarios Model (WESM). The model does not make use of Hubbert curves but instead relies on target reserve-to-production ratios to determine when regional output will begin to decline. The authors believe that their analysis has a bias toward optimism about oil resource availability because it does not attempt to incorporate political or environmental constraints on production, nor does it explicitly include geologic constraints on production rates. Global energy scenarios created by IIASA and WEC provide the context for the risk analysis. Key variables such as the quantity of undiscovered oil and rates of technological progress are treated as probability distributions, rather than constants. Analyses based on the USGS and IIASA resource assessments indicate that conventional oil production outside the Middle East is likely to peak sometime between 2010 and 2030. The most important determinants of the date are the quantity of undiscovered oil, the rate at which unconventional oil production can be expanded, and the rate of growth of reserves and enhanced recovery. Analysis based on data produced by Campbell indicates that the peak of non-Middle East production will occur before 2010. For total world conventional oil production, the results indicate a peak somewhere between 2020 and 2050. Key determinants of the peak in world oil production are the rate at which the Middle East region expands its output and the minimum reserves-to-production ratios producers will tolerate. Once world conventional oil production peaks, first oil sands and heavy oil from Canada, Venezuela and Russia, and later some other source such as shale oil from the United States must expand if total world oil consumption is to continue to increase. Alternative sources of liquid hydrocarbon fuels, such as coal or natural gas are also possible resources but not considered in this analysis nor is the possibility of transition to a hydrogen economy. These limitations were adopted to simplify the transition analysis. Inspection of the paths of conventional oil production indicates that even if world oil production does not peak before 2020, output of conventional oil is likely to increase at a substantially slower rate after that date. The implication is that there will have to be increased production of unconventional oil after that date if world petroleum consumption is to grow.

Innovative Technology Improves Upgrading Process for Unconventional Oil  

NLE Websites -- All DOE Office Websites (Extended Search)

09, 2013 09, 2013 Innovative Technology Improves Upgrading Process for Unconventional Oil Resources Washington, D.C. - An innovative oil-upgrading technology that can increase the economics of unconventional petroleum resources has been developed under a U.S. Department of Energy -funded project. The promising technology, developed by Ceramatec of Salt Lake City, Utah, and managed by the Office of Fossil Energy's National Energy Technology Laboratory, has been licensed to Western Hydrogen of Calgary for upgrading bitumen or heavy oil from Canada. A new company, Field Upgrading (Calgary, Alberta), has been formed dedicated to developing and commercializing the technology. Heavy oil is crude oil that is viscous and requires thermally enhanced oil recovery methods, such as steam and hot water injection, to reduce its viscosity and enable it to flow. The largest U.S. deposits of heavy oil are in California and on Alaska's North Slope. Estimates for the U.S. heavy oil resource total about 104 billion barrels of oil in place - nearly five times the United States' proved reserves. In addition, although no commercial-scale development of U.S. oil sands or oil shale has yet occurred, both represent another potential future domestic unconventional oil resource.

Report on variation of electrical conductivity during steam injection in unconsolidated sand saturated with a salt solution  

SciTech Connect

Geophysical electrical methods are useful in evaluating the performance of certain classes of enhanced oil recovery (EOR) operations and also remediation operations for contaminant spills. Electrical resistivity is sensitive to the concentration of ionic species in solution in fluids present in the subsurface zone. Such fluids are displaced during oil recovery operations and contaminant remediation. If the resistivity of the displacing fluid differs from the in situ fluid, then a geophysical method for detecting resistivity variations may be capable of tracking the advance of the displacing fluid. This report presents the results of experiments designed to determine the variations in resistivity that occur when steam is injected into a homogeneous, fully-saturated sand. These experiments were simple, one-dimensional laboratory steam injection experiments. They were performed using a glass tube filled with a tightly-packed sand and fitted with an injection port at one end and an exit port at the other In each experiment, the sand pack was initially saturated with a brine and then steam was introduced at one end of the tube. Analytic solutions for the steam front velocity, steam temperature, steam distribution, salt concentration profile, and liquid saturation are presented and are used with appropriate correlations of electrical conductivity to describe the observed behavior. The results of these experiments should provide experimental justification for the electrical conductivity variations that are calculated from the analytic solutions. In addition, the experiments may yield new information regarding features of the data that may not result from the analytical modelling.

High efficiency shale oil recovery  

SciTech Connect

The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated on a small scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant. Although an oil shale batch sample is sealed in the batch kiln from the start until the end of the run, the process conditions for the batch are the same as the conditions that an element of oil shale would encounter in a continuous process kiln. Similar chemical and physical (heating, mixing) conditions exist in both systems. The two most important data objectives in this phase of the project are to demonstrate (1) that the heat recovery projected for this project is reasonable and (2) that an oil shale kiln will run well and not plug up due to sticking and agglomeration. The following was completed and is reported on this quarter: (1) A software routine was written to eliminate intermittently inaccurate temperature readings. (2) We completed the quartz sand calibration runs, resolving calibration questions from the 3rd quarter. (3) We also made low temperature retorting runs to identify the need for certain kiln modifications and kiln modifications were completed. (4) Heat Conductance data on two Pyrolysis runs were completed on two samples of Occidental oil shale.

Tight gas sands study breaks down drilling and completion costs  

Science Conference Proceedings (OSTI)

Given the high cost to drill and complete tight gas sand wells, advances in drilling and completion technology that result in even modest cost savings to the producer have the potential to generate tremendous savings for the natural gas industry. The Gas Research Institute sponsored a study to evaluate drilling and completion costs in selected tight gas sands. The objective of the study was to identify major expenditures associated with tight gas sand development and determine their relative significance. A substantial sample of well cost data was collected for the study. Individual well cost data were collected from nearly 300 wells in three major tight gas sand formations: the Cotton Valley sand in East Texas, the Frontier sand in Wyoming, and the Wilcox sand in South Texas. The data were collected and organized by cost category for each formation. After the information was input into a data base, a simple statistical analysis was performed. The statistical analysis identified data discrepancies that were then resolved, and it helped allow conclusions to be drawn regarding drilling and completion costs in these tight sand formations. Results are presented.

Direct Production of Silicones From Sand  

Science Conference Proceedings (OSTI)

Silicon, in the form of silica and silicates, is the second most abundant element in the earth's crust. However the synthesis of silicones (scheme 1) and almost all organosilicon chemistry is only accessible through elemental silicon. Silicon dioxide (sand or quartz) is converted to chemical-grade elemental silicon in an energy intensive reduction process, a result of the exceptional thermodynamic stability of silica. Then, the silicon is reacted with methyl chloride to give a mixture of methylchlorosilanes catalyzed by cooper containing a variety of tract metals such as tin, zinc etc. The so-called direct process was first discovered at GE in 1940. The methylchlorosilanes are distilled to purify and separate the major reaction components, the most important of which is dimethyldichlorosilane. Polymerization of dimethyldichlorosilane by controlled hydrolysis results in the formation of silicone polymers. Worldwide, the silicones industry produces about 1.3 billion pounds of the basic silicon polymer, polydimethylsiloxane.

Sand-rich submarine fans, Mio-Pliocene of Santa Monica Basin, offshore California: Untapped exploration targets  

Science Conference Proceedings (OSTI)

Santa Monica Basin lies directly west of Los Angeles Basin, one of the world's most prolific oil provinces. Published literature suggests that Santa Monica Basin was starved of coarse clastics during the late Miocene through Pliocene. However, seismic sequence stratigraphy indicates that deposition of sand-rich fans alternated with mixed-load systems throughout the Delmontian and Repettian stages. Seismic sequences and facies are calibrated to seismic and well data from Beta Oil Field, in San Pedro Basin to the south. Eustasy evidently played a dominant role in controlling sedimentation. Variations in tan lithology, thickness, and basinward extent correspond to worldwide changes in sea level. Regional erosion surfaces apparently signify drops in sea level. Overlying thick seismic packages display hummocky to chaotic seismic facies separated by high- to low-amplitude continuous reflections. These configurations are interpreted as inner- to mid-fan channels separated by overbank deposits in sand-rich lowstand fans. High-amplitude basinwide reflections bound the tops of the sand-rich intervals, and likely represent condensed sections formed during sea-level rises. Thin seismic intervals above the condensed sections display downlap, and are interpreted as interbedded sandstones and shales of prograding highstand fans. Sediment input to Santa Monica Basin, based on seismic-facies and isochron patterns, was predominantly from the (present-day) north, with subordinate input from the east. High-amplitude eustatic variations dominated deposition and sequence development even in this tectonically active basin Previously unidentified sand-rich fans are present, and have not been drilled.

Heavy crude and tar sands: Hydrocarbons for the 21st century. Volume 2, Reservoir behavior, drilling and production  

SciTech Connect

Volume 2 is devoted to heavy oil reservoir behavior, production, and the drilling and completion of wells to meet the special needs of these fascinating but difficult oils and bitumens. The volume begins with four papers describing approaches to the recovery of heavy oil and to two fields subject to different recovery mechanisms. Although most heavy oil fields are produced with the assistance of steam stimulation, which commenced in Venezuela, or steam flood, many other methods for the improvement of recovery are potentially applicable. The seven reports on pilot projects examine mostly the results of studies on the dominant thermal recovery methods - steam stimulation, steam flood, and in situ combustion. The behavior of reservoirs under development through use of horizontal wells is the subject of three reports, of vertical wells, nine papers. Much is still to be teamed concerning the relative advantages of these two distinctive methods of reservoir development. The 18 reports on drilling and production are of great importance to the science and engineering of heavy oil because of the problems heavy oil causes after it is induced to flow to the well bore. Artificial lifting of the oil has traditionally centered on the use of sucker rods, but other methods, such as chamber or cavity-pump lift may prove to be efficacious. Horizontal well drilling is a logical approach to maximizing the amount of reservoir exposed to the well bore but this entails special problems in bore-hole clean-up. Heavy oils, too, pose special, frequently very difficult gravel packing problems. Sand production with heavy oil has always posed both economic and technological difficulties and major effort is devoted to overcoming them, as evidenced by the reports in this section. Individual papers have been processed separately for inclusion in the Energy Science and Technology Database.

Soil stabilization using oil-shale solid waste  

Science Conference Proceedings (OSTI)

Oil-shale solid wastes are evaluated for use as soil stabilizers. A laboratory study consisted of the following tests on compacted samples of soil treated with water and spent oil shale: unconfined compressive strength, moisture-density relationships, wet-dry and freeze-thaw durability, and resilient modulus. Significant increases in strength, durability, and resilient modulus were obtained by treating a silty sand with combusted western oil shale. Moderate increases in durability and resilient modulus were obtained by treating a highly plastic clay with combusted western oil shale. Solid waste from eastern oil shale appears to be feasible for soil stabilization only if limestone is added during combustion. Testing methods, results, and recommendations for mix design of spent shale-stabilized pavement subgrades are presented and the mechanisms of spent-shale cementation are discussed.

Characterization of nickel and vanadium compounds in tar sand bitumen by UV-VIS spectroscopy and size exclusion chromatography coupled with element specific detection  

Science Conference Proceedings (OSTI)

Previously, the authors examined the Ni and V in heavy crude oils, residua, and processed products by several metal speciation techniques to ascertain molecular structure and processing behavior. Two classes of metal compounds were found - metallopetroporphyrins and metallo-nonprophyrins - each having unique reactivity during processing. In efforts to better understand the binding of metals in the oil medium, they now examine NI and V in tar sand bitumens. The bitumen was solvent extracted from the sand matrix and was separated by column chromatography and the petroporphyrin content was quantitated by UV-vis spectroscopy. The petroporphyrin contents ranged from virtually none to over 36% of the total metals. Asphalt Ridge (Utah) has primarily Ni petroporphyrins; Big Clifty (Kentucky) and Athabasca (Canada) have primarily V petroporphyrins; Arroyo Grande and McKittrick (California) have roughly equal amounts of both types; and Sunnyside (Utah) has virtually none of either.

The apparent surface roughness of moving sand transported by wind  

E-Print Network (OSTI)

We present a comprehensive analytical model of aeolian sand transport in saltation. It quantifies the momentum transfer from the wind to the transported sand by providing expressions for the thickness of the saltation layer and the apparent surface roughness. These expressions are for the first time entirely derived from basic physical principles. The model further predicts the sand transport rate (mass flux) and the impact threshold shear velocity. We show that the model predictions are in very good agreement with experiments and numerical state of the art simulations of aeolian saltation.

Developing a tight gas sand advisor for completion and stimulation in tight gas reservoirs worldwide  

E-Print Network (OSTI)

As the demand for energy worldwide increases, the oil and gas industry will need to increase recovery from unconventional gas reservoirs (UGR). UGRs include Tight Gas Sand (TGS), coalbed methane and gas shales. To economically produce UGRs, one must have adequate product price and one must use the most current technology. TGS reservoirs require stimulation as a part of the completion, so improvement of completion practices is very important. We did a thorough literature review to extract knowledge and experience about completion and stimulation technologies used in TGS reservoirs. We developed the principal design and two modules of a computer program called Tight Gas Sand Advisor (TGS Advisor), which can be used to assist engineers in making decisions while completing and stimulating TGS reservoirs. The modules include Perforation Selection and Proppant Selection. Based on input well/reservoir parameters these subroutines provide unambiguous recommendations concerning which perforation strategy(s) and what proppant(s) are applicable for a given well. The most crucial parameters from completion best-practices analyses and consultations with experts are built into TGS Advisor's logic, which mimics human expert's decision-making process. TGS Advisor's recommended procedures for successful completions will facilitate TGS development and improve economical performance of TGS reservoirs.

Increasing Heavy Oil Reserves in the Wilmington Oil Field through Advanced Reservoir Characterization and Thermal Production Technologies  

SciTech Connect

The objective of this project is to increase the recoverable heavy oil reserves within sections of the Wilmington Oil Field, near Long Beach, California. This is realized through the testing and application of advanced reservoir characterization and thermal production technologies. It is hoped that the successful application of these technologies will result in their implementation throughout the Wilmington Field and through technology transfer, will be extended to increase the recoverable oil reserves in other slope and basin clastic (SBC) reservoirs. The existing steamflood in the Tar zone of Fault Block (FB) II-A has been relatively insufficient because of several producability problems which are common in SBC reservoir; inadequate characterization of the heterogeneous turbidite sands, high permeability thief zones, low gravity oil and non-uniform distribution of the remaining oil. This has resulted in poor sweep efficiency, high steam-oil ratios, and early breakthrough. Operational problems related to steam breakthrough, high reservoir pressure, and unconsolidated sands have caused premature well and downhole equipment failures. In aggregate, these reservoir and operational constraints have resulted in increased operating costs and decreased recoverable reserves.

INCREASING HEAVY OIL RESERVES IN THE WILMINGTON OIL FIELD THROUGH ADVANCED RESERVOIR CHARACTERIZATION AND THERMAL PRODUCTION TECHNOLOGIES  

SciTech Connect

The objective of this project is to increase the recoverable heavy oil reserves within sections of the Wilmington Oil Field, near Long Beach, California through the testing and application of advanced reservoir characterization and thermal production technologies. The successful application of these technologies will result in expanding their implementation throughout the Wilmington Field and, through technology transfer, to other slope and basin clastic (SBC) reservoirs. The existing steamflood in the Tar zone of Fault Block II-A (Tar II-A) has been relatively inefficient because of several producibility problems which are common in SBC reservoirs: inadequate characterization of the heterogeneous turbidite sands, high permeability thief zones, low gravity oil and non-uniform distribution of the remaining oil. This has resulted in poor sweep efficiency, high steam-oil ratios, and early steam breakthrough. Operational problems related to steam breakthrough, high reservoir pressure, and unconsolidated sands have caused premature well and downhole equipment failures. In aggregate, these reservoir and operational constraints have resulted in increased operating costs and decreased recoverable reserves. A suite of advanced reservoir characterization and thermal production technologies are being applied during the project to improve oil recovery and reduce operating costs.

The effects of psammophilous plants on sand dune dynamics  

E-Print Network (OSTI)

Psammophilous plants are special plants that flourish in sand moving environments. There are two main mechanisms by which the wind affects these plants: (i) sand drift exposes roots and covers branches--the exposed roots turn into new plants and the covered branches turn into new roots; both mechanisms result in an enhanced growth rate of the psammophilous plant cover of the dunes; (ii) strong winds, often associated with sand movement, tear branches and seed them in nearby locations, resulting in new plants and an enhanced growth rate of the psammophilous plant cover of the dunes. Despite their important role in dune dynamics, to our knowledge, psammophilous plants have never been incorporated into mathematical models of sand dunes. Here, we attempt to model the effects of these plants on sand dune dynamics. We construct a set of three ordinary differential equations for the fractions of surface cover of regular vegetation, biogenic soil crust and psammophilous plants. The latter reach their optimal growth under (i) specific sand drift or (ii) specific wind power. We show that psammophilous plants enrich the sand dune dynamics. Depending on the climatological conditions, it is possible to obtain one, two, or three steady dune states. The activity of the dunes can be associated with the surface cover--bare dunes are active, and dunes with significant cover of vegetation, biogenic soil crust, or psammophilous plants are fixed. Our model shows that under suitable precipitation rates and wind power, the dynamics of the different cover types is in accordance with the common view that dunes are initially stabilized by psammophilous plants that reduce sand activity, thus enhancing the growth of regular vegetation that eventually dominates the cover of the dunes and determines their activity.

Experimental investigation of caustic steam injection for heavy oils  

E-Print Network (OSTI)

An experimental study has been conducted to compare the effect of steam injection and caustic steam injection in improving the recovery of San Ardo and Duri heavy oils. A 67 cm long x 7.4 cm O.D (outer diameter), steel injection cell is used in the study. Six thermocouples are placed at specific distances in the injection cell to record temperature profiles and thus the steam front velocity. The injection cell is filled with a mixture of oil, water and sand. Steam is injected at superheated conditions of 238oC with the cell outlet pressure set at 200 psig, the cell pressure similar to that found in San Ardo field. The pressure in the separators is kept at 50 psig. The separator liquid is sampled at regular intervals. The liquid is centrifuged to determine the oil and water volumes, and oil viscosity, density and recovery. Acid number measurements are made by the titration method using a pH meter and measuring the EMF values. The interfacial tensions of the oil for different concentrations of NaOH are also measured using a tensionometer. Experimental results show that for Duri oil, the addition of caustic results in an increase in recovery of oil from 52% (steam injection) to 59 % (caustic steam injection). However, caustic has little effect on San Ardo oil where oil recovery is 75% (steam injection) and 76 % (caustic steam injection). Oil production acceleration is seen with steam-caustic injection. With steam caustic injection there is also a decrease in the produced oil viscosity and density for both oils. Sodium hydroxide concentration of 1 wt % is observed to give the lowest oil-caustic interfacial tension. The acid numbers for San Ardo and Duri oil are measured as 6.2 and 3.57 respectively.

DOE Patents (OSTI)

A procedure for tagging sand with a radioisotope for use in the study of sediment transport involves the precipitation of a metal radioisotope in the form of an iodide directly on the sand, followed by heating the sand to a temperature sufficient to effect a phase transformation of the sand and a decomposition of the metal iodide, leaving the metal firmly attached to the sand.

Residual oil saturation determination. Wilmington micellar-polymer project. Final report  

SciTech Connect

The City of Long Beach, California conducted a program to obtain residual oil saturation (ROS) data in the HX/sub a/ Sand, Fault Block VB, Wilmington Field. This program utilized many complementary techniques for determining the ROS in a watered-out unconsolidated sand, typical of many reservoirs in the California Coastal Province. This program was to be performed in two stages. The first, Phase 1, was intended to determine the ROS in an area which had been flooded out during the course of a peripheral waterflood and to make a comparative analysis of current methods for determination of in-situ oil in place. The second stage, Phase 2 of the ROS program, was intended to measure the ROS after tertiary recovery by a micellar-polymer flood; however, the second phase was not carried out for lack of funds. This report describes the diagnostic tools and techniques which have been used to establish ROS. It then presents a comparative analysis of the results obtained using the different techniques. Inasmuch as the determination of in-situ oil saturation is directly dependent upon the in-situ value for porosity, it is required that the pore volume as a fraction of the reservoir rock be determined before the residual oil equation can be solved. Because of this, much of the study necessarily was concerned with measurement of porosity of the unconsolidated sand. The method finally used to obtain a very good core recovery in this highly unconsolidated sand is described. Present oil saturation and oil content of the HX/sub a/ sand in the Pilot is now believed to be better defined. This conclusion is supported by results obtained for electrical log analysis, analysis of full sized native state cores run under stress conditions, plug core analysis under stressed conditions and a Single-Well Tracer Survey. 15 references, 18 figures, 16 tables.

Increasing heavy oil reserves in the Wilmington Oil Field through advanced reservoir characterization and thermal production technologies. Annual report, March 30, 1995--March 31, 1996  

SciTech Connect

The objective of this project is to increase heavy oil reserves in a portion of the Wilmington Oil Field, near Long Beach, California, by implementing advanced reservoir characterization and thermal production technologies. Based on the knowledge and experience gained with this project, these technologies are intended to be extended to other sections of the Wilmington Oil Field, and, through technology transfer, will be available to increase heavy oil reserves in other slope and basin clastic (SBC) reservoirs. The project involves implementing thermal recovery in the southern half of the Fault Block II-A Tar zone. The existing steamflood in Fault Block II-A has been relatively inefficient due to several producibility problems which are common in SBC reservoirs. Inadequate characterization of the heterogeneous turbidite sands, high permeability thief zones, low gravity oil, and nonuniform distribution of remaining oil have all contributed to poor sweep efficiency, high steam-oil ratios, and early steam breakthrough. Operational problems related to steam breakthrough, high reservoir pressure, and unconsolidated formation sands have caused premature well and downhole equipment failures. In aggregate, these reservoir and operational constraints have resulted in increased operating costs and decreased recoverable reserves. A suite of advanced reservoir characterization and thermal production technologies are being applied during the project to improve oil recovery efficiency and reduce operating costs.

This research is the outgrowth of a survey paper I prepared for the Air Transport Association of America. I am grateful to Kristoffer Laursen for research assistance and to Kristoffer and Stefan Nagel for their comments. Abstract This paper explores the impact of investor flows and financial market conditions on returns in crude-oil futures markets. I begin by arguing that informational frictions and the associated speculative activity may induce prices to drift away from "fundamental" values and show increased volatility. This is followed by a discussion of the interplay between imperfect infor- mation about real economic activity, including supply, demand, and inventory accumulation, and speculative

Potential for substitution of geothermal energy at domestic defense installations and White Sands Missile Range  

DOE Green Energy (OSTI)

Geothermal resources that might provide substitute energy at any of 76 defense installations are identified and evaluated. The geologic characteristics and related economics of potential geothermal resources located at or near the 76 installations were estimated. The geologic assessment identified 18 installations with possible geothermal resources and 4 Atlantic Coastal Plain resource configurations that represented the alternatives available to East Coast bases. These 18 locations and 4 resource configurations, together with 2 possible resources at the White Sands Missile Range and a potential resource at Kings Bay, Georgia, were examined to determine the relative economics of substituting potential geothermal energy for part or all of the existing oil, gas, and electrical energy usage. Four of the military installations - Mountain Home, Norton, Hawthorne, and Sierra - appear to be co-located with possible geothermal resources which, if present, might provide substitute energy at or below current market prices for oil. Six additional locations - Ellsworth, Luke, Williams, Bliss, Fallon, and Twentynine Palms - could become economically attractive under certain conditions. No geothermal resource was found to be economically competitive with natural gas at current controlled prices. Generation of electric power at the locations studied is estimated to be uneconomic at present.

HEAVY AND THERMAL OIL RECOVERY PRODUCTION MECHANISMS  

SciTech Connect

The Stanford University Petroleum Research Institute (SUPRI-A) studies oil recovery mechanisms relevant to thermal and heavy-oil production. The scope of work is relevant across near-, mid-, and long-term time frames. In August of 2000 we received funding from the U. S. DOE under Award No. DE-FC26-00BC15311 that completed December 1, 2003. The project was cost shared with industry. Heavy oil (10 to 20{sup o} API) is an underutilized energy resource of tremendous potential. Heavy oils are much more viscous than conventional oils. As a result, they are difficult to produce with conventional recovery methods. Heating reduces oil viscosity dramatically. Hence, thermal recovery is especially important because adding heat, usually via steam injection generally improves displacement efficiency. The objectives of this work were to improve our understanding of the production mechanisms of heavy oil under both primary and enhanced modes of operation. The research described spanned a spectrum of topics related to heavy and thermal oil recovery and is categorized into: (1) multiphase flow and rock properties, (2) hot fluid injection, (3) improved primary heavy-oil recovery, (4) in-situ combustion, and (5) reservoir definition. Technology transfer efforts and industrial outreach were also important to project effort. The research tools and techniques used were quite varied. In the area of experiments, we developed a novel apparatus that improved imaging with X-ray computed tomography (CT) and high-pressure micromodels etched with realistic sandstone roughness and pore networks that improved visualization of oil-recovery mechanisms. The CT-compatible apparatus was invaluable for investigating primary heavy-oil production, multiphase flow in fractured and unfractured media, as well as imbibition. Imbibition and the flow of condensed steam are important parts of the thermal recovery process. The high-pressure micromodels were used to develop a conceptual and mechanistic picture of primary heavy-oil production by solution gas drive. They allowed for direct visualization of gas bubble formation, bubble growth, and oil displacement. Companion experiments in representative sands and sandstones were also conducted to understand the mechanisms of cold production. The evolution of in-situ gas and oil saturation was monitored with CT scanning and pressure drop data. These experiments highlighted the importance of depletion rate, overburden pressure, and oil-phase chemistry on the cold production process. From the information provided by the experiments, a conceptual and numerical model was formulated and validated for the heavy-oil solution gas drive recovery process. Also in the area of mechanisms, steamdrive for fractured, low permeability porous media was studied. Field tests have shown that heat injected in the form of steam is effective at unlocking oil from such reservoir media. The research reported here elucidated how the basic mechanisms differ from conventional steamdrive and how these differences are used to an advantage. Using simulations of single and multiple matrix blocks that account for details of heat transfer, capillarity, and fluid exchange between matrix and fracture, the importance of factors such as permeability contrast between matrix and fracture and oil composition were quantified. Experimentally, we examined the speed and extent to which steam injection alters the permeability and wettability of low permeability, siliceous rocks during thermal recovery. Rock dissolution tends to increase permeability moderately aiding in heat delivery, whereas downstream the cooled fluid deposits silica reducing permeability. Permeability reduction is not catastrophic. With respect to wettability, heat shifts rock wettability toward more water wet conditions. This effect is beneficial for the production of heavy and medium gravity oils as it improves displacement efficiency. A combination of analytical and numerical studies was used to examine the efficiency of reservoir heating using nonconventional wells such as horizontal and multi

Fluvial-deltaic heavy oil reservoir, San Joaquin basin  

SciTech Connect

Unconsolidated arkosic sands deposited in a fluvial-deltaic geologic setting comprise the heavy oil (13/degree/ API gravity) reservoir at South Belridge field. The field is located along the western side of the San Joaquin basin in Kern County, California. More than 6000 closely spaced and shallow wells are the key to producing the estimated 1 billion bbl of ultimate recoverable oil production. Thousands of layered and laterally discontinuous reservoir sands produce from the Pleistocene Tulare Formation. The small scale of reservoir geometries is exploited by a high well density, required for optimal heavy oil production. Wells are typically spaced 200-500 ft (66-164 m) apart and drilled to 1000 ft (328 m) deep in the 14-mi/sup 2/ (36-km/sup 2/) producing area. Successful in-situ combustion, cyclic steaming, and steamflood projects have benefited from the shallow-depth, thick, layered sands, which exhibit excellent reservoir quality. The fundamental criterion for finding another South Belridge field is to realize the extraordinary development potential of shallow, heavy oil reservoirs, even when an unspectacular discovery well is drilled. The trap is a combination of structural and stratigraphic mechanisms plus influence from unconventional fluid-level and tar-seal traps. The depositional model is interpreted as a braid delta sequence that prograded from the nearby basin-margin highlands. A detailed fluvial-deltaic sedimentologic model establishes close correlation between depositional lithofacies, reservoir geometries, reservoir quality, and heavy oil producibility. Typical porosity is 35% and permeability is 3000 md.

INCREASING WATERFLOOD RESERVES IN THE WILMINGTON OIL FIELD THROUGH IMPROVED RESERVOIR CHARACTERIZATION AND RESERVOIR MANAGEMENT  

Science Conference Proceedings (OSTI)

This project increased recoverable waterflood reserves in slope and basin reservoirs through improved reservoir characterization and reservoir management. The particular application of this project is in portions of Fault Blocks IV and V of the Wilmington Oil Field, in Long Beach, California, but the approach is widely applicable in slope and basin reservoirs. Transferring technology so that it can be applied in other sections of the Wilmington Field and by operators in other slope and basin reservoirs is a primary component of the project. This project used advanced reservoir characterization tools, including the pulsed acoustic cased-hole logging tool, geologic three-dimensional (3-D) modeling software, and commercially available reservoir management software to identify sands with remaining high oil saturation following waterflood. Production from the identified high oil saturated sands was stimulated by recompleting existing production and injection wells in these sands using conventional means as well as a short radius redrill candidate. Although these reservoirs have been waterflooded over 40 years, researchers have found areas of remaining oil saturation. Areas such as the top sand in the Upper Terminal Zone Fault Block V, the western fault slivers of Upper Terminal Zone Fault Block V, the bottom sands of the Tar Zone Fault Block V, and the eastern edge of Fault Block IV in both the Upper Terminal and Lower Terminal Zones all show significant remaining oil saturation. Each area of interest was uncovered emphasizing a different type of reservoir characterization technique or practice. This was not the original strategy but was necessitated by the different levels of progress in each of the project activities.

Oil price; oil demand shocks; oil supply shocks; dynamic effects.  

E-Print Network (OSTI)

Abstract: Using a newly developed measure of global real economic activity, a structural decomposition of the real price of crude oil in four components is proposed: oil supply shocks driven by political events in OPEC countries; other oil supply shocks; aggregate shocks to the demand for industrial commodities; and demand shocks that are specific to the crude oil market. The latter shock is designed to capture shifts in the price of oil driven by higher precautionary demand associated with fears about future oil supplies. The paper quantifies the magnitude and timing of these shocks, their dynamic effects on the real price of oil and their relative importance in determining the real price of oil during 1975-2005. The analysis sheds light on the origin of the observed fluctuations in oil prices, in particular during oil price shocks. For example, it helps gauge the relative importance of these shocks in the build-up of the real price of crude oil since the late 1990s. Distinguishing between the sources of higher oil prices is shown to be crucial in assessing the effect of higher oil prices on U.S. real GDP and CPI inflation, suggesting that policies aimed at dealing with higher oil prices must take careful account of the origins of higher oil prices. The paper also quantifies the extent to which the macroeconomic performance of the U.S. since the mid-1970s has been driven by the external economic shocks driving the real price of oil as opposed to domestic economic factors and policies.

Mechanism of acoustic emissions from booming sand dunes  

E-Print Network (OSTI)

The classical elastic mechanics shows that the fundamental frequency of a sand grain chain is similar to the typical frequency of acoustic emission generated by the booming dunes. The "song of dunes" is therefore considered to originate from the resonance of grain chains occurring within a solid layer only several centimeters thick.

CO{sub 2}/sand fracturing in low permeability reservoirs  

Science Conference Proceedings (OSTI)

The objectives of this study are: to demonstrate the effectiveness of a non-damaging liquid, carbon dioxide (CO{sub 2}) in creating sand-propped hydraulic fractures in ``tight`` gas bearing formations within the Appalachian Basin; and to compare and rank the gas production responses from wells treated with liquid CO{sub 2} with other types of treatments (shooting, water based, nitrogen, etc.). The preliminary results are encouraging, and although only a few months of production is available, the rate of gas production from the CO{sub 2} treated candidate wells is greater than that from the control wells. The CO{sub 2}/sand fracs appear to be 56 percent better than the nitrogen fracs in Pike County. In addition, the CO{sub 2}/sand fracs are 4.8 times better than conventional shot wells in the Pike County study area. It should be recognized that these results are from a very limited data set and overall conclusions may change as more control wells are added to the analysis. From a stimulation process achievement viewpoint, the maximum amount of sand pumped is 46,000 pounds at an average concentration of 3.1 pound per gallon. It should be pointed out that additional foam and nitrogen stimulations have recently been performed by the operator in the Pike County area, and subsequent discussions in the future will include additional control wells to the baseline data sets.

Coupling the Alkaline-Surfactant-Polymer Technology and The Gelation Technology to Maximize Oil Production  

SciTech Connect

Gelation technologies have been developed to provide more efficient vertical sweep efficiencies for flooding naturally fractured oil reservoirs or more efficient areal sweep efficiency for those with high permeability contrast ''thief zones''. The field proven alkaline-surfactant-polymer technology economically recovers 15% to 25% OOIP more oil than waterflooding from swept pore space of an oil reservoir. However, alkaline-surfactant-polymer technology is not amenable to naturally fractured reservoirs or those with thief zones because much of injected solution bypasses target pore space containing oil. This work investigates whether combining these two technologies could broaden applicability of alkaline-surfactant-polymer flooding into these reservoirs. A prior fluid-fluid report discussed interaction of different gel chemical compositions and alkaline-surfactant-polymer solutions. Gel solutions under dynamic conditions of linear corefloods showed similar stability to alkaline-surfactant-polymer solutions as in the fluid-fluid analyses. Aluminum-polyacrylamide, flowing gels are not stable to alkaline-surfactant-polymer solutions of either pH 10.5 or 12.9. Chromium acetate-polyacrylamide flowing and rigid flowing gels are stable to subsequent alkaline-surfactant-polymer solution injection. Rigid flowing chromium acetate-polyacrylamide gels maintained permeability reduction better than flowing chromium acetate-polyacrylamide gels. Silicate-polyacrylamide gels are not stable with subsequent injection of either a pH 10.5 or a 12.9 alkaline-surfactant-polymer solution. Chromium acetate-xanthan gum rigid gels are not stable to subsequent alkaline-surfactant-polymer solution injection. Resorcinol-formaldehyde gels were stable to subsequent alkaline-surfactant-polymer solution injection. When evaluated in a dual core configuration, injected fluid flows into the core with the greatest effective permeability to the injected fluid. The same gel stability trends to subsequent alkaline-surfactant-polymer injected solution were observed. Aluminum citrate-polyacrylamide, resorcinol-formaldehyde, and the silicate-polyacrylamide gel systems did not produce significant incremental oil in linear corefloods. Both flowing and rigid flowing chromium acetate-polyacrylamide gels and the xanthan gum-chromium acetate gel system produced incremental oil with the rigid flowing gel producing the greatest amount. Higher oil recovery could have been due to higher differential pressures across cores. None of the gels tested appeared to alter alkaline-surfactant-polymer solution oil recovery. Total waterflood plus chemical flood oil recovery sequence recoveries were all similar. Chromium acetate-polyacrylamide gel used to seal fractured core maintain fracture closure if followed by an alkaline-surfactant-polymer solution. Chromium acetate gels that were stable to injection of alkaline-surfactant-polymer solutions at 72 F were stable to injection of alkaline-surfactant-polymer solutions at 125 F and 175 F in linear corefloods. Chromium acetate-polyacrylamide gels maintained diversion capability after injection of an alkaline-surfactant-polymer solution in stacked; radial coreflood with a common well bore. Xanthan gum-chromium acetate gels maintained gel integrity in linear corefloods after injection of an alkaline-surfactant-polymer solution at 125 F. At 175 F, Xanthan gum-chromium acetate gels were not stable either with or without subsequent alkaline-surfactant-polymer solution injection. Numerical simulation demonstrated that reducing the permeability of a high permeability zone of a reservoir with gel improved both waterflood and alkaline-surfactant-polymer flood oil recovery. A Minnelusa reservoir with both A and B sand production was simulated. A and B sands are separated by a shale layer. A sand and B sand waterflood oil recovery was improved by 196,000 bbls when a gel was placed in the B sand. A sand and B sand alkaline-surfactant-polymer flood oil recovery was improved by 596,000 bbls when a gel was placed in the B sand. Alkaline-surfactant-pol

Examination of pulverized waste recycled glass as filter media in slow sand filtration. Final report  

SciTech Connect

The purpose of this study was to investigate the pulverization of waste recycled glass to produce glass sand for slow sand filters. Pulverization experiments were performed using a fail mill pulverizer. The glass sand product from the pulverizer meets the size distribution requirements of ASTM-C-33 without size distribution adjustment. The size distribution must be adjusted to meet the grain size distribution requirements of the Ten States Standards and the USEPA for filter media used in slow sand filters. Pulverized glass that meet slow sand filter media specifications is an effective alternative to silica sand as a filter media for slow sand filtration. Three pilot plant slow sand filters with glass sand filter media were compared to a fourth filter containing silica sand filter media. Over an 8 month period of continuous operation, the performance of the glass sand filter media was as good or better than the silica sands, with removals of 56% to 96% for turbidity; 99.78% to 100.0% for coliform bacteria; 99.995% to 99.997% for giardia cysts; 99.92% and 99.97% for cryptosporidium oocysts. Based on a cost-benefit analysis, converting waste glass into filter media may be economically advantageous for recycling facilities.

Feasibility study of heavy oil recovery in the Midcontinent region (Kansas, Missouri, Oklahoma)  

SciTech Connect

This report is one of a series of publications assessing the feasibility/constraints of increasing domestic heavy oil production. Each report covers a select area of the United States. The Midcontinent (Kansas, Nssouri, Oklahoma) has produced significant oil, but contrary to early reports, the area does not contain the huge volumes of heavy oil that, along with the development of steam and in situ combustion as oil production technologies, sparked the area`s oil boom of the 1960s. Recovery of this heavy oil has proven economically unfeasible for most operators due to the geology of the formations rather than the technology applied to recover the oil. The geology of the southern Midcontinent, as well as results of field projects using thermal enhanced oil recovery (TEOR) methods to produce the heavy oil, was examined based on analysis of data from secondary sources. Analysis of the performance of these projects showed that the technology recovered additional heavy oil above what was produced from primary production from the consolidated, compartmentalized, fluvial dominated deltaic sandstone formations in the Cherokee and Forest City basins. The only projects producing significant economic and environmentally acceptable heavy oil in the Midcontinent are in higher permeability, unconsolidated or friable, thick sands such as those found in south-central Oklahoma. There are domestic heavy oil reservoirs in other sedimentary basins that are in younger formations, are less consolidated, have higher permeability and can be economically produced with current TEOR technology. Heavy oil production from the carbonates of central and wester Kansas has not been adequately tested, but oil production is anticipated to remain low. Significant expansion of Midcontinent heavy oil production is not anticipated because the economics of oil production and processing are not favorable.

INCREASING HEAVY OIL RESERVES IN THE WILMINGTON OIL FIELD THROUGH ADVANCED RESERVOIR CHARACTERIZATION AND THERMAL PRODUCTION TECHNOLOGIES  

SciTech Connect

The objective of this project is to increase the recoverable heavy oil reserves within sections of the Wilmington Oil Field, near Long Beach, California, through the testing and application of advanced reservoir characterization and thermal production technologies. The hope is that successful application of these technologies will result in their implementation throughout the Wilmington Field and, through technology transfer, will be extended to increase the recoverable oil reserves in other slope and basin clastic (SBC) reservoirs. The existing steamflood in the Tar zone of Fault Block II-A (Tar II-A) has been relatively inefficient because of several producibility problems which are common in SBC reservoirs: inadequate characterization of the heterogeneous turbidite sands, high permeability thief zones, low gravity oil and non-uniform distribution of the remaining oil. This has resulted in poor sweep efficiency, high steam-oil ratios, and early steam breakthrough. Operational problems related to steam breakthrough, high reservoir pressure, and unconsolidated sands have caused premature well and downhole equipment failures. In aggregate, these reservoir and operational constraints have resulted in increased operating costs and decreased recoverable reserves. A suite of advanced reservoir characterization and thermal production technologies are being applied during the project to improve oil recovery and reduce operating costs, including: (1) Development of three-dimensional (3-D) deterministic and stochastic reservoir simulation models--thermal or otherwise--to aid in reservoir management of the steamflood and post-steamflood phases and subsequent development work. (2) Development of computerized 3-D visualizations of the geologic and reservoir simulation models to aid reservoir surveillance and operations. (3) Perform detailed studies of the geochemical interactions between the steam and the formation rock and fluids. (4) Testing and proposed application of a novel alkaline-steam well completion technique for the containment of the unconsolidated formation sands and control of fluid entry and injection profiles. (5) Installation of a 2100 ft, 14 inch insulated, steam line beneath a harbor channel to supply steam to an island location. (6) Testing and proposed application of thermal recovery technologies to increase oil production and reserves: (a) Performing pilot tests of cyclic steam injection and production on new horizontal wells. (b) Performing pilot tests of hot water-alternating-steam (WAS) drive in the existing steam drive area to improve thermal efficiency. (7) Perform a pilot steamflood with the four horizontal injectors and producers using a pseudo steam-assisted gravity-drainage (SAGD) process. (8) Advanced reservoir management, through computer-aided access to production and geologic data to integrate reservoir characterization, engineering, monitoring and evaluation.

Application of turbidite facies of the Stevens Oil Zone for reservoir management, Elk Hills Field, California  

SciTech Connect

A detailed depositional model for the uppermost sand reservoirs of the Stevens Oil Zone, Elk Hills Field, California, contains three facies: turbidite channel-fill sand bodies, overbank Sandstone and mudstone, and pelagic and hemipelagic siliceous shale. Sand bodies are the primary producing facies and consist of layered, graded sandstone with good permeability. The presence of incipient anticlines with subsea relief in the late Miocene resulted in deposition of lenticular and sinuous sand Was within structurally created channels. Relief of these structural channels was low when the earliest sand bodies were deposited, leading to a wide channel complex bounded by broad overbank deposits of moderate to low permeability. As deposition proceeded, increased structural relief constrained the channels, resulting in narrower sand body width and relatively abrupt channel terminations against very low permeability siliceous shale. With post-Miocene uplift and differential compaction, stratigraphic mounding of sand bodies helped create structural domes such as the 24Z reservoir. Stratigraphic traps including the 26R reservoir were also created. Such traps vary in seal quality from very effective to leaky, depending on the lateral transition from sand bodies to siliceous shale. Application of the Elk Hills turbidity model (1) provides a framework for monitoring production performance in the 24Z and Northwest Stevens waterflood projects; and for tracking gas migration into and out of the 26R reservoir, (2) helps b identify undeveloped locations in the 26R reservoir ideally suited for horizontal wells, (3) has led to the identification of two new production trends in the 29R area, and (4) makes possible the development of exploration plays in western Elk Hills.

Shredded tires and rubber-sand as lightweight backfill  

Science Conference Proceedings (OSTI)

The growing interest in utilizing waste materials in civil engineering applications has opened the possibility of constructing reinforced soil structures with unconventional backfills. Scrap tires are a high-profile waste material for which several uses have been studied, including the use of shredded tires as backfill. A triaxial testing program was conducted to investigate the stress-strain relationship and strength of tire chips and a mixture of sand and tire chips. The test results and additional information from the literature were used in the numerical modeling of wall backfills, both unreinforced and reinforced with geosynthetics. The numerical modeling results suggest tire shreds, particularly when mixed with sand, may be effectively used as a backfill.

An unconsolidated gas-producing sand in which the permeability is layered and the productivity can be impaired by liquid blocking can be consolidated by wetting the rock surfaces with a limited amount of water, injecting a smoke which selectively reduces the permeability of the most permeable layers by depositing on their faces unconsolidated masses of substantially inert solid particles and injecting a gaseous silicon polyhalide to convert a significant proportion of the rock surface-wettingwater to a grain bonding silica gel.

Project Drum Inlet: explosive excavation in saturated sand  

SciTech Connect

Seasonal storms during February of 1971 completely closed the Drum Inlet navigation channel through the Outer Banks off the North Carolina coast. This channel is highly useful to commercial and sport fishing industries in the Carteret County vicinity of North Carolina, and is vital to maintenance of the ecological balance in the inland Core Sound waters. To reopen Drum Inlet, an alignment about 2.1 miles south of the original location was selected. A contract dredge excavated a channel from the inland Core Sound waterway to and part way through the Outer Banks. The final 385-ft-long section of sand separating the Core Sound from the Atlantic Ocean was excavated with large explosive charges, This report describes the explosive excavation of that portion of the channel. Twenty-two separate canisters, each containing 1 ton of aluminized ammonium-nitrate slurry blasting agent, were emplaced in two rows. All charges were detonated simultaneously at 1327 hours, 23 Decembcr 1971. The detonation successfully removed the sand barrier, forming a continuous channel over 80 ft in width. This channel subsequently washed out to a width of about 1000 ft and was used:is an access route to the Raleigh Bay fishing grounds. The Drum Inlet project demonstrated the practicality of explosive channel excavation in saturated sand under the special conditions encountered at this site. (auth)

Soil stabilization using oil shale solid wastes: Laboratory evaluation of engineering properties  

Science Conference Proceedings (OSTI)

Oil shale solid wastes were evaluated for possible use as soil stabilizers. A laboratory study was conducted and consisted of the following tests on compacted samples of soil treated with water and spent oil shale: unconfined compressive strength, moisture-density relationships, wet-dry and freeze-thaw durability, and resilient modulus. Significant increases in strength, durability, and resilient modulus were obtained by treating a silty sand with combusted western oil shale. Moderate increases in strength, durability, and resilient modulus were obtained by treating a highly plastic clay with combusted western oil shale. Solid waste from eastern shale can be used for soil stabilization if limestone is added during combustion. Without limestone, eastern oil shale waste exhibits little or no cementation. The testing methods, results, and recommendations for mix design of spent shale-stabilized pavement subgrades are presented. 11 refs., 3 figs., 10 tabs.

INCREASING HEAVY OIL RESERVES IN THE WILMINGTON OIL FIELD THROUGH ADVANCED RESERVOIR CHARACTERIZATION AND THERMAL PRODUCTION TECHNOLOGIES  

Science Conference Proceedings (OSTI)

The project involves using advanced reservoir characterization and thermal production technologies to improve thermal recovery techniques and lower operating and capital costs in a slope and basin clastic (SBC) reservoir in the Wilmington field, Los Angeles Co., CA. Through June 2002, project work has been completed on the following activities: data preparation; basic reservoir engineering; developing a deterministic three dimensional (3-D) geologic model, a 3-D deterministic reservoir simulation model and a rock-log model; well drilling and completions; and surface facilities on the Fault Block II-A Tar Zone (Tar II-A). Work is continuing on research to understand the geochemistry and process regarding the sand consolidation well completion technique, final reservoir tracer work, operational work and research studies to prevent thermal-related formation compaction in the Tar II-A steamflood area, and operational work on the Tar V post-steamflood pilot and Tar II-A post-steamflood projects. During the Third Quarter 2002, the project team essentially completed implementing the accelerated oil recovery and reservoir cooling plan for the Tar II-A post-steamflood project developed in March 2002 and is proceeding with additional related work. The project team has completed developing laboratory research procedures to analyze the sand consolidation well completion technique and will initiate work in the fourth quarter. The Tar V pilot steamflood project terminated hot water injection and converted to post-steamflood cold water injection on April 19, 2002. Proposals have been approved to repair two sand consolidated horizontal wells that sanded up, Tar II-A well UP-955 and Tar V well J-205, with gravel-packed inner liner jobs to be performed next quarter. Other well work to be performed next quarter is to convert well L-337 to a Tar V water injector and to recomplete vertical well A-194 as a Tar V interior steamflood pattern producer. Plans have been approved to drill and complete well A-605 in Tar V in the first quarter 2003. Plans have been approved to update the Tar II-A 3-D deterministic reservoir simulation model and run sensitivity cases to evaluate the accelerated oil recovery and reservoir cooling plan. The Tar II-A post-steamflood operation started in February 1999 and steam chest fillup occurred in September-October 1999. The targeted reservoir pressures in the ''T'' and ''D'' sands are maintained at 90 {+-} 5% hydrostatic levels by controlling water injection and gross fluid production and through the bimonthly pressure monitoring program enacted at the start of the post-steamflood phase. Well work related to the Tar II-A accelerated oil recovery and reservoir cooling plan began in March 2002 with oil production increasing from 1009 BOPD in the first quarter to 1145 BOPD in the third quarter. Reservoir pressures have been increased during the quarter from 88% to 91% hydrostatic levels in the ''T'' sands and from 91% to 94% hydrostatic levels in the ''D'' sands. Well work during the quarter is described in the Reservoir Management section. The post-steamflood production performance in the Tar V pilot project has been below projections because of wellbore mechanical limitations and the loss of a horizontal producer a second time to sand inflow that are being addressed in the fourth quarter. As the fluid production temperatures exceeded 350 F, our self-imposed temperature limit, the pilot steamflood was converted to a hot waterflood project in June 2001 and converted to cold water injection on April 19, 2002.

DEVELOPMENT OF SHALLOW VISCOUS OIL RESERVES IN NORTH SLOPE  

SciTech Connect

North Slope of Alaska has huge oil deposits in heavy oil reservoirs such as Ugnu, West Sak and Shrader Bluff etc. The viscosity of the last two reservoir oils vary from {approx}30 cp to {approx}3000 cp and the amount in the range of 10-20 billion barrels. High oil viscosity and low formation strength impose problems to high recovery and well productivity. Water-alternate-gas injection processes can be effective for the lower viscosity end of these deposits in West Sak and Shrader Bluff. Several gas streams are available in the North Slope containing NGL and CO{sub 2} (a greenhouse gas). The goal of this research is to develop tools to find optimum solvent, injection schedule and well-architecture for a WAG process in North Slope shallow sand viscous oil reservoirs. In the last quarter, we added numerical solution along streamline subroutines to our streamline compositional simulator. The WAG injection algorithms are being developed. We studied the wettability of the reservoir oil and formulated a four-phase relative permeability model based on two-phase relative permeabilities. The effect of new relative permeability formulations on a five-spot pattern WAG recovery was evaluated. Effect of horizontal wells on pattern sweep has been initiated. A model quarter five-spot experiment is being designed. Plans for the next quarter includes modeling of WAG injection in streamline based simulation, evaluation of complex well-architecture and design of model quarter five-spot experiment.

Canyon dissolution of sand, slag, and crucible residues  

Science Conference Proceedings (OSTI)

An alternative to the FB-Line scrap recovery dissolver was desired for the dissolution of sand, slag, and crucible (SS{ampersand}C) residues from the plutonium reduction process due to the potential generation of hydrogen gas concentrations above the lower flammability limit. To address this concern, a flowsheet was developed for the F-Canyon dissolvers. The dissolvers are continually purged with nominally 33 SCFM of air; therefore the generation of flammable gas concentrations should not be a concern. Following removal of crucible fragments, small batches of the remaining sand fines or slag chunks containing less than approximately 350 grams of plutonium can be dissolved using the center insert in each of the four annular dissolver ports to address nuclear criticality safety concerns. Complete dissolution of the sand fines and slag chunks was achieved in laboratory experiments by heating between 75 and 85 degrees Celsius in a 9.3M nitric acid/0.013M (hydrogen) fluoride solution. Under these conditions, the sand and slag samples dissolved between 1 and 3 hours. Complete dissolution of plutonium and calcium fluorides in the slag required adjusting the dissolver solution to 7.5 wt% aluminum nitrate nonahydrate (ANN). Once ANN was added to a dissolver solution, further dissolution of any plutonium oxide (PuO2) in successive charges was not practical due to complexation of the fluoride by aluminum. During the laboratory experiments, well mixed solutions were necessary to achieve rapid dissolution rates. When agitation was not provided, sand fines dissolved very slowly. Measurement of the hydrogen gas generation rate during dissolution of slag samples was used to estimate the amount of metal in the chunks. Depending upon the yield of the reduction, the values ranged between approximately 1 (good yield) and 20% (poor yield). Aging of the slag will reduce the potential for hydrogen generation as calcium metal oxidizes over time. The potential for excessive corrosion in the dissolvers was evaluated using experimental data reported in the literature. Corrosion data at the exact flowsheet conditions were not available; however, the corrosion rate for 304L stainless steel (wrought material) corrosion coupons in 10M nitric acid/0.01M hydrofluoric acid at 95 degrees Celsius was reported as 21 mils per year. If the fluoride in the dissolver is complexed with aluminum, the corrosion rate will decrease to approximately 5 mils per year.

National Metal Casting Research Institute final report. Volume 1, Sand reclamation  

Science Conference Proceedings (OSTI)

A mobile thermal foundry sand reclamation unit was designed and constructed. This unit consisted of thermal and mechanical sand reclamation equipment installed on the bed of a 50 foot low-boy trailer. It was transported to a number of Midwest foundries for on-site demonstration of the sand reclamation process. This allowed participating foundries to have their own refuse sand (10-100 tons) processed and then reused in production for evaluation. The purpose for building the unit was to demonstrate to foundries through ``hands on`` experience that refuse sands can be reclaimed and successfully reused particularly in regard to product quality. Most of the participating foundries indicated a high level of satisfaction with the reclaimed sand. Laboratory testing of samples of the used sand, before and after processing by the demonstration unit, verified the usability of the reclaimed sand. One of the foundries participating was a brass foundry, the sand from this foundry contained lead and is classified as a hazardous material. After reclamation the sand was no longer hazardous and could also be reused in the foundry.

Increasing Heavy Oil Reserves in the Wilmington Oil Field Through Advanced Reservoir Characterization and Thermal Production Technologies  

SciTech Connect

The project involves improving thermal recovery techniques in a slope and basin clastic (SBC) reservoir in the Wilmington field, Los Angeles Co., Calif. using advanced reservoir characterization and thermal production technologies. The existing steamflood in the Tar zone of Fault Block (FB) II-A has been relatively inefficient because of several producibility problems which are common in SBC reservoirs. Inadequate characterization of the heterogeneous turbidite sands, high permeability thief zones, low gravity oil, and nonuniform distribution of remaining oil have all contributed to poor sweep efficiency, high steam-oil ratios, and early steam breakthrough. Operational problems related to steam breakthrough, high reservoir pressure, and unconsolidated formation sands have caused premature well and downhole equipment failures. In aggregate, these reservoir and operational constraints have resulted in increased operating costs and decreased recoverable reserves. The advanced technologies to be applied include: (1) Develop three-dimensional (3-D) deterministic and stochastic geologic models. (2) Develop 3-D deterministic and stochastic thermal reservoir simulation models to aid in reservoir management and subsequent development work. (3) Develop computerized 3-D visualizations of the geologic and reservoir simulation models to aid in analysis. (4) Perform detailed study on the geochemical interactions between the steam and the formation rock and fluids. (5) Pilot steam injection and production via four new horizontal wells (2 producers and 2 injectors). (6) Hot water alternating steam (WAS) drive pilot in the existing steam drive area to improve thermal efficiency. (7) Installing a 2100 foot insulated, subsurface harbor channel crossing to supply steam to an island location. (8) Test a novel alkaline steam completion technique to control well sanding problems and fluid entry profiles. (9) Advanced reservoir management through computer-aided access to production and geologic data to integrate reservoir characterization, engineering, monitoring, and evaluation.

Non-Darcy flow analysis through tight sand formations  

SciTech Connect

An experimental setup was designed and constructed to measure the flow parameters through tight sand porous media. The two kinds of coreholders being used are Hassler-type and one in which the core sample is encapsulated in layers of epoxy resin and metal alloy. A gas flow measuring system was also developed for accurately measuring very low gas flow rates. Using Darcy's Law as a tool for analysis of the experimental data, we obtained that the gas permeability of the SFE No. 3 (Staged Field Experiment No. 3) core samples is a linear function of reciprocal mean pressure, and decreases with overburden pressure. The water permeability is also decreased with overburden pressure and is about 6 times smaller than gas permeability for the samples that we have tested. No significant hysteresis effect was obtained for dry gas permeability after several two phase flow runs. We successfully tested our encapsulated coreholder and measured gas flow rate through a tight sand core sample at different pressure drops. The results showed that the experimental runs using Hassler-type coreholder at overburden pressures higher than 2000 psig will probably give us the reliable experimental data. The experimental data obtained from the two different types of tight sandstones were analyzed using the Non-Darcy flow equation. The results showed the importance and reliability of the Non-Darcy formulation for describing the flow behavior under different overburden and system pressures. Non-Darcy's velocity for both gas and liquid phase were incorporated into an existing FORTRAN code for simulation of the tight gas reservoirs. The modified program was tested to compare the initial production data of SFE No. 2 well. Our simulation showed in the case of local turbulence and non-uniformities in the tight sand formation, the value of [beta] increases and Non-Darcy effect becomes important.

CO{sub 2}/sand fracturing in Devonian shales  

Science Conference Proceedings (OSTI)

A total of five carbon dioxide (CO{sub 2})/sand well stimulations were successfully executed with two Devonian shale operators in Perry and Pike Counties, Kentucky. This new stimulation method offers a minimum formation damage proppant stimulation approach for natural gas producers in the United States. Some operators have been concerned about the frac fluid formation damage associated with the water and chemicals used in conventional foam stimulations, whereas other operators have been concerned about the lack of proppant in straight nitrogen fracs used by service companies today. Two carefully screened geological areas of established Devonian shale production were selected based on active ongoing drilling and completion operations. One selected control area contained an existing set of wells with established production histories. More specifically, one operator furnished three offset wells which were stimulated with the carbon dioxide/sand frac method. The quantity of proppant and fluids pumped during each well stimulation ranged from 23,000 to 43,000 pounds of proppant and from 120 to 160 tons of liquid carbon dioxide. Another operator furnished two offset wells which were each stimulated with approximately 47,000 pounds of proppant and 120 tons of carbon dioxide. The logistics and field layout of a typical carbon dioxide/sand frac treatment has been described and highlighted. The importance and unique aspects of the closed system blender that is required for job execution is discussed. Five stimulation treatments have been reviewed, and stimulation and preliminary production data compared to offset wells stimulated with nitrogen, and explosives. Initial production results indicate more than a 50 percent increase in production rate compared to nitrogen fraced wells in the Pike County area.

Production process for glass sand from the quartz waste from the beneficiation of kingiseppsk phosphorites  

SciTech Connect

This paper presents a process developed for the production of molding sand from the quartz waste which makes it possible to simplify the system for obtaining glass sand. According to this system, the main operation in the removal of most of the residual phosphate shell and alkaline earth metal oxides from the quartz waste is foam separation, using the residual concentration of reagents in the pulp (tallow and kerosene). After the subsequent washing and hydraulic classification, the sands meet the requirements set for molding sands grade Ob2K. The characteristics of the original flotation tailings and molding sand are presented. The mineralogical analysis of the molding sand showed that the iron-containing impurities are grains of glauconite, films of iron oxide on the surface of the grains, grains of ferrous-dolomite cement, and iron from the apparatus.

Heavy oil reservoirs recoverable by thermal technology. Annual report  

SciTech Connect

The purpose of this study was to compile data on reservoirs that contain heavy oil in the 8 to 25/sup 0/ API gravity range, contain at least ten million barrels of oil currently in place, and are non-carbonate in lithology. The reservoirs within these constraints were then analyzed in light of applicable recovery technology, either steam-drive or in situ combustion, and then ranked hierarchically as candidate reservoirs. The study is presented in three volumes. Volume I presents the project background and approach, the screening analysis, ranking criteria, and listing of candidate reservoirs. The economic and environmental aspects of heavy oil recovery are included in appendices to this volume. This study provides an extensive basis for heavy oil development, but should be extended to include carbonate reservoirs and tar sands. It is imperative to look at heavy oil reservoirs and projects on an individual basis; it was discovered that operators, and industrial and government analysts will lump heavy oil reservoirs as poor producers, however, it was found that upon detailed analysis, a large number, so categorized, were producing very well. A study also should be conducted on abandoned reservoirs. To utilize heavy oil, refiners will have to add various unit operations to their processes, such as hydrotreaters and hydrodesulfurizers and will require, in most cases, a lighter blending stock. A big problem in producing heavy oil is that of regulation; specifically, it was found that the regulatory constraints are so fluid and changing that one cannot settle on a favorable recovery and production plan with enough confidence in the regulatory requirements to commit capital to the project.

Appraisal of the tight sands potential of the Sand Wash and Great Divide Basins. Final report, June 1989--June 1991  

Science Conference Proceedings (OSTI)

The volume of future tight gas reserve additions is difficult to estimate because of uncertainties in the characterization and extent of the resource and the performance and cost-effectiveness of stimulation and production technologies. Ongoing R&D by industry and government aims to reduce the risks and costs of producing these tight resources, increase the certainty of knowledge of their geologic characteristics and extent, and increase the efficiency of production technologies. Some basins expected to contain large volumes of tight gas are being evaluated as to their potential contribution to domestic gas supplies. This report describes the results of one such appraisal. This analysis addresses the tight portions of the Eastern Greater Green River Basin (Sand Wash and Great Divide Subbasins in Northwestern Colorado and Southwestern Wyoming, respectively), with respect to estimated gas-in-place, technical recovery, and potential reserves. Geological data were compiled from public and proprietary sources. The study estimated gas-in-place in significant (greater than 10 feet net sand thickness) tight sand intervals for six distinct vertical and 21 areal units of analysis. These units of analysis represent tight gas potential outside current areas of development. For each unit of analysis, a ``typical`` well was modeled to represent the costs, recovery and economics of near-term drilling prospects in that unit. Technically recoverable gas was calculated using reservoir properties and assumptions about current formation evaluation and extraction technology performance. Basin-specific capital and operating costs were incorporated along with taxes, royalties and current regulations to estimate the minimum required wellhead gas price required to make the typical well in each of unit of analysis economic.

DEVELOPMENT OF SHALLOW VISCOUS OIL RESERVES IN NORTH SLOPE  

Science Conference Proceedings (OSTI)

North Slope of Alaska has huge oil deposits in heavy oil reservoirs such as Ugnu, West Sak and Shrader Bluff etc. The viscosity of the last two reservoir oils vary from {approx}30 cp to {approx}3000 cp and the amount in the range of 10-20 billion barrels. High oil viscosity and low formation strength impose problems to high recovery and well productivity. Water-alternate-gas injection processes can be effective for the lower viscosity end of these deposits in West Sak and Shrader Bluff. Several gas streams are available in the North Slope containing NGL and CO{sub 2} (a greenhouse gas). The goal of this research is to develop tools to find optimum solvent, injection schedule and well-architecture for a WAG process in North Slope shallow sand viscous oil reservoirs. In the last quarter, we have developed streamline generation and convection subroutines for miscible gas injection. The WAG injection algorithms are being developed. We formulated a four-phase relative permeability model based on two-phase relative permeabilities. The new relative permeability formulations are being incorporated into the simulator. Wettabilities and relative permeabilities are being measured. Plans for the next quarter includes modeling of WAG injection in streamline based simulation, relative permeability studies with cores, incorporation of complex well-architecture.

Canadian incentives for oil and gas exploration. [Applicability to USA  

Science Conference Proceedings (OSTI)

During the 1970s a number of different exploration and production incentive programs were put in place in Canada, in particular in the Province of Alberta, Canada's principal oil- and gas-producing province. The DOE/RA is evaluating Canadian incentives for oil and gas exploration, and this study is intended to provide information that will help guide DOE/RA in determining the applicability of Canadian incentive programs in US energy policy. The study describes and documents the fiscal structure in which the Canadian oil industry operates. The incentive features of pricing policy, taxation policy, and provincial royalty systems are discussed. A principal focus of the study is on one of the most important of Canada's specific incentive programs, the Alberta Exploratory Drilling Incentive Credit Program (EDICP). The study describes and evaluates the effect of the EDICP on increased oil and gas exploration activity. Similarly, the study also reviews and evaluates other specific incentive programs such as the Alberta Geophysical Incentive Program, Frontier Exploration Allowances, and various tar sand and heavy oil development incentives. Finally the study evaluates the applicability of Canadian incentives to US energy policy.

Cased-hole measurement of oil in place, San Joaquin Valley, California  

SciTech Connect

A log-inject-log (LIL) method was used to measure residual oil through casing in a reservoir with relatively fresh formation water. Water saturations calculated from pulsed-neutron-capture cross sections logged before and after injection of brine agree within about 10 saturation units (s.u.) with saturations previously measured from cores and from the electromagnetic propagation tool (EPT) run in openhole. Well completion and injection procedures were designed to achieve uniform injection without altering the unconsolidated sand containing liquids at low pressures. Residual oil in place (OIP) measured by cores, the EPT, and the LIL method represents saturation after thorough flushing by water. 15 refs.

Oil shale commercialization study  

SciTech Connect

Ninety four possible oil shale sections in southern Idaho were located and chemically analyzed. Sixty-two of these shales show good promise of possible oil and probable gas potential. Sixty of the potential oil and gas shales represent the Succor Creek Formation of Miocene age in southwestern Idaho. Two of the shales represent Cretaceous formations in eastern Idaho, which should be further investigated to determine their realistic value and areal extent. Samples of the older Mesozonic and paleozoic sections show promise but have not been chemically analyzed and will need greater attention to determine their potential. Geothermal resources are of high potential in Idaho and are important to oil shale prospects. Geothermal conditions raise the geothermal gradient and act as maturing agents to oil shale. They also might be used in the retorting and refining processes. Oil shales at the surface, which appear to have good oil or gas potential should have much higher potential at depth where the geothermal gradient is high. Samples from deep petroleum exploration wells indicate that the succor Creek shales have undergone considerable maturation with depth of burial and should produce gas and possibly oil. Most of Idaho's shales that have been analyzed have a greater potential for gas than for oil but some oil potential is indicated. The Miocene shales of the Succor Creek Formation should be considered as gas and possibly oil source material for the future when technology has been perfectes. 11 refs.

Producing Light Oil from a Frozen Reservoir: Reservoir and Fluid Characterization of Umiat Field, National Petroleum Reserve, Alaska  

Science Conference Proceedings (OSTI)

Umiat oil field is a light oil in a shallow, frozen reservoir in the Brooks Range foothills of northern Alaska with estimated oil-in-place of over 1 billion barrels. Umiat field was discovered in the 1940’s but was never considered viable because it is shallow, in the permafrost, and far from any transportation infrastructure. The advent of modern drilling and production techniques has made Umiat and similar fields in northern Alaska attractive exploration and production targets. Since 2008 UAF has been working with Renaissance Alaska Inc. and, more recently, Linc Energy, to develop a more robust reservoir model that can be combined with rock and fluid property data to simulate potential production techniques. This work will be used to by Linc Energy as they prepare to drill up to 5 horizontal wells during the 2012-2013 drilling season. This new work identified three potential reservoir horizons within the Cretaceous Nanushuk Formation: the Upper and Lower Grandstand sands, and the overlying Ninuluk sand, with the Lower Grandstand considered the primary target. Seals are provided by thick interlayered shales. Reserve estimates for the Lower Grandstand alone range from 739 million barrels to 2437 million barrels, with an average of 1527 million bbls. Reservoir simulations predict that cold gas injection from a wagon-wheel pattern of multilateral injectors and producers located on 5 drill sites on the crest of the structure will yield 12-15% recovery, with actual recovery depending upon the injection pressure used, the actual Kv/Kh encountered, and other geologic factors. Key to understanding the flow behavior of the Umiat reservoir is determining the permeability structure of the sands. Sandstones of the Cretaceous Nanushuk Formation consist of mixed shoreface and deltaic sandstones and mudstones. A core-based study of the sedimentary facies of these sands combined with outcrop observations identified six distinct facies associations with distinctive permeability trends. The Lower Grandstand sand consists of two coarsening-upward shoreface sands sequences while the Upper Grandstand consists of a single coarsening-upward shoreface sand. Each of the shoreface sands shows a distinctive permeability profile with high horizontal permeability at the top getting progressively poorer towards the base of the sand. In contrast, deltaic sandstones in the overlying Ninuluk are more permeable at the base of the sands, with decreasing permeability towards the sand top. These trends impart a strong permeability anisotropy to the reservoir and are being incorporated into the reservoir model. These observations also suggest that horizontal wells should target the upper part of the major sands. Natural fractures may superimpose another permeability pattern on the Umiat reservoir that need to be accounted for in both the simulation and in drilling. Examination of legacy core from Umiat field indicate that fractures are present in the subsurface, but don't provide information on their orientation and density. Nearby surface exposures of folds in similar stratigraphy indicate there are at least three possible fracture sets: an early, N/S striking set that may predate folding and two sets possibly related to folding: an EW striking set of extension fractures that are parallel to the fold axes and a set of conjugate shear fractures oriented NE and NW. Analysis of fracture spacing suggests that these natural fractures are fairly widely spaced (25-59 cm depending upon the fracture set), but could provide improved reservoir permeability in horizontal legs drilled perpendicular to the open fracture set. The phase behavior of the Umiat fluid needed to be well understood in order for the reservoir simulation to be accurate. However, only a small amount of Umiat oil was available; this oil was collected in the 1940’s and was severely weathered. The composition of this ‘dead’ Umiat fluid was characterized by gas chromatography. This analysis was then compared to theoretical Umiat composition derived using the Pedersen method with original Umiat

Ecological Consequences of Landscape Fragmentation on the Lizard Community in the Mescalero-Monahans Shinnery Sands  

E-Print Network (OSTI)

Landscape fragmentation poses a major threat to biodiversity world-wide. The goal of my dissertation research was to determine the effects of landscape fragmentation on a lizard community in the Mescalero-Monahans shinnery sands, New Mexico and the extent to which conservation efforts might protect biodiversity in this ecosystem. My research relied heavily on data collected from a large-scale spatially-replicated comparative study. The purpose of this study was to evaluate the impacts of landscape fragmentation as a result of oil and gas development on the dunes sagebrush lizard (Sceloporus arenicolus). Results from analysis of lizard community structure indicate that fragmented sites are less diverse than non-fragmented sites. In particular, two species are found in lower density and occupancy in the fragmented locations (Holbrookia maculata and Sceloporus arenicolus). Analysis of landscape configuration at the scale of a trapping grid indicated that sand dune blowout shape and size differed between fragmented and non-fragmented locations. Differences in landscape pattern were associated with reduced lizard diversity. Because of this association between lower diversity and altered landscape pattern, extensive alterations to landscape pattern may cause disassembly at the ecosystem level. The maintenance of existing landscape pattern may be important to the maintenance of diversity in this ecosystem. Evaluations of habitat use patterns of the lizards in this community demonstrate that a few species have narrow preferences for certain habitats. In particular, H. maculata, Phrynosoma cornutum, and S. arenicolus all demonstrated narrow habitat use patterns. Effect size of fragmentation for each species indicated that the same three species showed a large effect when comparing their average abundances between fragmented and non-fragmented locations. Thus species that are most likely to benefit or be harmed by landscape fragmentation are those with the most specific habitat requirements. Umbrella species represent one of many approaches to conservation using surrogate species. I used data on ants, beetles, small mammals, lizards, and endemic species to test the use of the dunes sagebrush lizard (Sceloporus arenicolus) as an umbrella for endemism and biodiversity of the Mescalero-Monahans shinnery sands ecosystem. I applied a comparative approach at three spatial scales to examine how conservation practices at different scales may affect biodiversity and endemism in this ecosystem. At the largest scale, the frequency of occurrence for endemic species increased though no other patterns emerged because S. arenicolus was present at all sites and there were no relationships between relative abundances of S. arenicolus and the other taxonomic groups. At the smallest scale, both beetle species richness, diversity, and endemic species richness were higher in the presence of S. arenicolus. To protect biodiversity in this ecosystem, conservation efforts should focus on protection at the scale of the species distribution rather than on the small-scale placement of individual well pads.

Increasing Waterflood Reserves in the Wilmington Oil Field Through Improved Reservoir Characterization and Reservoir Management  

Science Conference Proceedings (OSTI)

The objectives of this quarterly report are to summarize the work conducted under each task during the reporting period January - March 1998 and to report all technical data and findings as specified in the "Federal Assistance Reporting Checklist". The main objective of this project is the transfer of technologies, methodologies, and findings developed and applied in this project to other operators of Slope and Basin Clastic Reservoirs. This project will study methods to identify sands with high remaining oil saturation and to recomplete existing wells using advanced completion technology. The identification of the sands with high remaining oil saturation will be accomplished by developing a deterministic three dimensional (3-D) geologic model and by using a state of the art reservoir management computer software. The wells identified by the geologic and reservoir engineering work as having the best potential will be logged with cased-hole logging tools. The application of the logging tools will be optimized in the lab by developing a rock-log model. This rock-log model will allow us to translate measurements through casing into effective porosity and hydrocarbon saturation. The wells that are shown to have the best oil production potential will be recompleted. The recompletions will be optimized by evaluating short radius lateral recompletions as well as other recompletion techniques such as the sand consolidation through steam injection.

Locating and producing bypassed oil: A U.S. DOE project update  

SciTech Connect

Tidelands Oil Production Co. is conducting a Class 3 near-term waterflood project supported partially by the US Dept. of Energy (USDOE) titled Increasing Waterflood Reserves in the Wilmington Oil Field Through Improved Reservoir Characterization and Reservoir Management. The project takes place across Fault Blocks 4 and 5 of the Wilmington field, Long Beach, California. The objective of this U.S. DOE demonstration project is to increase waterflood reserves in slope and basin clastic reservoirs through improved methods of identifying sands containing oil bypassed by a waterflood and exploiting this oil by recompleting existing idle wells. Specific objectives include identifying sands containing high remaining-oil saturation by use of a multiple acoustic cased-hole logging tool, determining geophysical parameters for interpretation of the acoustic data, demonstrating and gaining experience with a short-radius lateral recompletion, optimizing standard and steam recompletion techniques, generating a three-dimensional (3D) geologic model, and transferring the developed technologies and methods to other operators of slope and basin clastic reservoirs. The paper discusses results to date on characterization, reservoir engineering, deterministic modeling, multiple acoustic logging, and recompletions.

Crude Oil Analysis Database  

DOE Data Explorer (OSTI)

The composition and physical properties of crude oil vary widely from one reservoir to another within an oil field, as well as from one field or region to another. Although all oils consist of hydrocarbons and their derivatives, the proportions of various types of compounds differ greatly. This makes some oils more suitable than others for specific refining processes and uses. To take advantage of this diversity, one needs access to information in a large database of crude oil analyses. The Crude Oil Analysis Database (COADB) currently satisfies this need by offering 9,056 crude oil analyses. Of these, 8,500 are United States domestic oils. The database contains results of analysis of the general properties and chemical composition, as well as the field, formation, and geographic location of the crude oil sample.

INCREASING HEAVY OIL RESERVES IN THE WILMINGTON OIL FIELD THROUGH ADVANCED RESERVOIR CHARACTERIZATION AND THERMAL PRODUCTION TECHNOLOGIES  

SciTech Connect

The overall objective of this project is to increase heavy oil reserves in slope and basin clastic (SBC) reservoirs through the application of advanced reservoir characterization and thermal production technologies. The project involves improving thermal recovery techniques in the Tar Zone of Fault Blocks II-A and V (Tar II-A and Tar V) of the Wilmington Field in Los Angeles County, near Long Beach, California. A primary objective is to transfer technology which can be applied in other heavy oil formations of the Wilmington Field and other SBC reservoirs, including those under waterflood. The thermal recovery operations in the Tar II-A and Tar V have been relatively inefficient because of several producibility problems which are common in SBC reservoirs. Inadequate characterization of the heterogeneous turbidite sands, high permeability thief zones, low gravity oil, and nonuniform distribution of remaining oil have all contributed to poor sweep efficiency, high steam-oil ratios, and early steam breakthrough. Operational problems related to steam breakthrough, high reservoir pressure, and unconsolidated formation sands have caused premature well and downhole equipment failures. In aggregate, these reservoir and operational constraints have resulted in increased operating costs and decreased recoverable reserves. The advanced technologies to be applied include: (1) Develop three-dimensional (3-D) deterministic and stochastic geologic models. (2) Develop 3-D deterministic and stochastic thermal reservoir simulation models to aid in reservoir management and subsequent development work. (3) Develop computerized 3-D visualizations of the geologic and reservoir simulation models to aid in analysis. (4) Perform detailed study on the geochemical interactions between the steam and the formation rock and fluids. (5) Pilot steam injection and production via four new horizontal wells (2 producers and 2 injectors). (6) Hot water alternating steam (WAS) drive pilot in the existing steam drive area to improve thermal efficiency. (7) Installing an 2400 foot insulated, subsurface harbor channel crossing to supply steam to an island location. (8) Test a novel alkaline steam completion technique to control well sanding problems and fluid entry profiles. (9) Advanced reservoir management through computer-aided access to production and geologic data to integrate reservoir characterization, engineering, monitoring, and evaluation.

In particular, very little research has been conducted with respect to in-situ oil upgrading using hydrogen donor under in-situ combustion. Several papers describe the use of metal additives mixed with oil and their influence on oil properties such as viscosity and API gravity. The main objective of my research is to determine if a catalyst mixed with a hydrogen donor (tetralin) is going to affect the Jobo crude oil properties while undergoing in-situ combustion. Six runs were performed with Jobo crude oil (9-11ºAPI) from the Orinoco Belt in Venezuela. Four of the runs were successful. Two of them are base runs; the remaining ones are with tetralin with concentration of 5 wt% (of oil) and catalyst with concentration of 750 ppm. For all runs, the following were kept constant: the air injection rate (3 std. L/min) and production (combustion tube outlet) pressure, 300 psig. Concentration by weight of oil, water, and sand in the samples were approximately 4.8%, 4.2%, and 91% respectively. Oil viscosity at the end of combustion at 40oC decreased from 42.3 and 73.6 to 16.6 and 25.2; API gravity at the end of combustion increased from 18.4 and 16.8 to 20 and 18.8. Oil recovery is higher; combustion front velocity is faster in the case of additives, water production decreased. Since oil viscosity decreased and API gravity increased oil moves faster and consequently combustion time is lower.

Effect of temperature on wave velocities in sands and sandstones with heavy hydrocarbons  

SciTech Connect

A laboratory investigation was made of the effects of temperature on wave velocities in sandstones and unconsolidated sand saturated with heavy hydrocarbons. The large decreases of the compressional and shear velocities in such sandstones and sand with increasing temperature suggest that seismic methods may be very useful in detecting heat fronts in heavy hydrocarbon reservoirs undergoing steamflooding or in-situ combustion.

Preliminary relative permeability estimates of methanehydrate-bearing sand  

Science Conference Proceedings (OSTI)

The relative permeability to fluids in hydrate-bearing sediments is an important parameter for predicting natural gas production from gas hydrate reservoirs. We estimated the relative permeability parameters (van Genuchten alpha and m) in a hydrate-bearing sand by means of inverse modeling, which involved matching water saturation predictions with observations from a controlled waterflood experiment. We used x-ray computed tomography (CT) scanning to determine both the porosity and the hydrate and aqueous phase saturation distributions in the samples. X-ray CT images showed that hydrate and aqueous phase saturations are non-uniform, and that water flow focuses in regions of lower hydrate saturation. The relative permeability parameters were estimated at two locations in each sample. Differences between the estimated parameter sets at the two locations were attributed to heterogeneity in the hydrate saturation. Better estimates of the relative permeability parameters require further refinement of the experimental design, and better description of heterogeneity in the numerical inversions.

DEVELOPMENT PRACTICES FOR OPTIMIZED MEOR IN SHALLOW HEAVY OIL RESERVOIRS  

Science Conference Proceedings (OSTI)

The objective of this research project is to demonstrate an economically viable and sustainable method of producing shallow heavy oil reserves in western Missouri and southeastern Kansas, using an integrated approach including surface geochemical surveys, conventional MEOR treatments, horizontal fracturing in vertical wells, electrical resistivity tomography (ERT), and reservoir simulation to optimize the recovery process. The objective also includes transferring the knowledge gained from the project to other local landowners, to demonstrate how they may identify and develop their own heavy oil resources with minimal capital investment. Tasks completed in the first six-month period include soil sampling, geochemical analysis, construction of ERT arrays, collection of background ERT surveys, and analysis of core samples to develop a geomechanical model for designing the hydraulic fracturing treatment. Five wells were to be drilled in phase I. However, weather and funding delays resulted in drilling shifting to the second phase of the project. Work performed to date demonstrates that surface geochemical methods can be used to differentiate between productive and non-productive areas of the Warner Sand and that ERT can be used to successfully image through the Warner Sand.

Horizontal well improves oil recovery from polymer flood--  

Science Conference Proceedings (OSTI)

Horizontal drilling associated with an injection scheme appears to be highly promising for obtaining additional oil recovery. Horizontal well CR 163H, in the Chateaurenard field is discussed. It demonstrated that a thin unconsolidated sand can be successfully drilled and cased. The productivity index (PI) of the well was much greater than vertical wells, and an unproduced oil bank was successfully intersected. On the negative side, it was necessary to pump low in a very deviated part of the well, and the drilling cost was high compared to an onshore vertical well. CR 163H was the fifth and probably most difficult horizontal well drilled by Elf Aquitaine. Located within a polymer-flood project, the target was a 7-m thick sand reservoir at a vertical depth of 590:0080 m. In this inverted seven-spot configuration with one injector in the center and six producers at a distance of 400 m, a polymer solution was injected from 1977 to 1983, followed by water injection.

CO{sub 2}/sand fracturing in Devonian shale  

Science Conference Proceedings (OSTI)

A total of five carbon dioxide (CO{sub 2}) /sand well stimulations were successfully executed with two Devonian shale operators in Perry and Pike Counties, Kentucky. This new stimulation method offers a minimum formation damage proppant stimulation approach for natural gas producers in the United States. Some operators have been concerned about the frac fluid formation damage associated with the water and chemicals used in conventional foam stimulations, whereas other operators have been concerned about the lack of proppant in straight nitrogen fracs used by service companies today. Two carefully screened geological areas of established Devonian shale production were selected based on active ongoing drilling and completion operations. One selected control area contained an existing set of wells with established production histories. The logistics and field layout of a typical carbon dioxide/sand frac treatment has been described and highlighted. The importance and unique aspects of the closed system blender that is required for job execution is discussed. Five stimulation treatments have been reviewed, and stimulation and preliminary production data compared to offset wells stimulated with nitrogen, and explosives. Initial production results indicate more than a 50 percent increase in production rate compared to nitrogen fraced wells in the Pike County area. In addition, production is also 4.8 times better than conventional shot wells in the same area. These results are encouraging enough to formally combine existing pumping equipment, a closed system blender, and liquid carbon dioxide supplies to develop a new fracturing service in the eastern US A total of 22 additional jobs are planned in the eastern US in low permeability gas formations over the next year.

Shale oil: process choices  

SciTech Connect

The four broad categories of shale-oil processing are discussed. All of these processes share the basic function of retorting oil-shale rock at high temperature so that the kerogen material in the rocks is thermally decomposed to shale oil and gaseous products. The technologies and the organizations working on their development are: solids-to-solids heating, The Oil Shale Co. (TOSCO) and Lurgi-Rhur; gas-to-solids heating with internal gas combustion, U. S. Bureau of Mines, Development Engineering Inc. and Union Oil of California; gas-to-solid heating with external heat generation, Development Engineering, Union Oil, Petrobas, and Institute of Gas Technology; and in-situ retorting, Occidental Petroleum Corp.

Economic Implementation and Optimization of Secondary Oil Recovery  

Science Conference Proceedings (OSTI)

The St Mary West Barker Sand Unit (SMWBSU or Unit) located in Lafayette County, Arkansas was unitized for secondary recovery operations in 2002 followed by installation of a pilot injection system in the fall of 2003. A second downdip water injection well was added to the pilot project in 2005 and 450,000 barrels of saltwater has been injected into the reservoir sand to date. Daily injection rates have been improved over initial volumes by hydraulic fracture stimulation of the reservoir sand in the injection wells. Modifications to the injection facilities are currently being designed to increase water injection rates for the pilot flood. A fracture treatment on one of the production wells resulted in a seven-fold increase of oil production. Recent water production and increased oil production in a producer closest to the pilot project indicates possible response to the water injection. The reservoir and wellbore injection performance data obtained during the pilot project will be important to the secondary recovery optimization study for which the DOE grant was awarded. The reservoir characterization portion of the modeling and simulation study is in progress by Strand Energy project staff under the guidance of University of Houston Department of Geosciences professor Dr. Janok Bhattacharya and University of Texas at Austin Department of Petroleum and Geosystems Engineering professor Dr. Larry W. Lake. A geologic and petrophysical model of the reservoir is being constructed from geophysical data acquired from core, well log and production performance histories. Possible use of an outcrop analog to aid in three dimensional, geostatistical distribution of the flow unit model developed from the wellbore data will be investigated. The reservoir model will be used for full-field history matching and subsequent fluid flow simulation based on various injection schemes including patterned water flooding, addition of alkaline surfactant-polymer (ASP) to the injected water, and high pressure air injection (HPAI) for in-situ low temperature oxidization (LTO) will be studied for optimization of the secondary recovery process.

Oil from rock  

SciTech Connect

The article discusses first the Green River Formation oil shale projects in the western United States from which conservative estimates have suggested an output of 400,000 to 600,000 bbl/day of crude shale oil by 1990. The western reserves recoverable with present technology are said to exceed 600 billion (10/sup 9/) bbl. Three major considerations could limit the large-scale development of shale oil: availability of water, environmental factors, and socio-economic considerations. Water is used to obtain and process the crude shale oil, and additional water is needed to cool the spent shale and to establish new vegetation on top of it. Nitrogenous compounds and arsenic in crude shale oil are among potential pollutants. Spent shale contains salts that are potentially leachable, as well as organic pyrolytic products. Retorting oil shales may release more CO/sub 2/ through decomposition of carbonate minerals that will subsequently be generated by burning the oil produced. Topographic effects of oil shale mining may raise socio-economic problems. Next the article discusses the conversion of coal to liquid by pyrolysis or hydrogenation, including the Gulf solvent refined coal (SRC) and the Exxon (EDS) liquefaction processes. Also described in the South African SASOL process for producing synthetic fuel from coal. A parallel account is included on the estimated complete cycle of United States and of worldwide crude oil production, forecasting depletion within less than a century. 11 refs.

Oil spill response resources  

E-Print Network (OSTI)

Pollution has become one of the main problems being faced by humanity. Preventing pollution from occurring might be the best idea but is not possible in this fast developing world. So the next best thing to do would be to respond to the pollution source in an effective manner. Oil spills are fast becoming pollution sources that are causing the maximum damage to the environment. This is owing to the compounds that are released and the way oil spreads in both water and land. Preventing the oil spill would be the best option. But once the oil has been spilled, the next best thing to do is to respond to the spill effectively. As a result, time becomes an important factor while responding to an oil spill. Appropriate response to contain and cleanup the spill is required to minimize its potential damage to the ecosystem. Since time and money play a very important role in spill response, it would be a great idea if decisions can be made in such a way that a quick response can be planned. The first part of this study deals with the formation of an 'Oil Spill Resources Handbook', which has information on all the important Oil Spill Contractors. The second and the main part of the study, deals with creating a database in Microsoft Access of the Oil Spill Contractors. The third portion of the study deals with planning an oil spill response using a systems approach.

Reactivation of an Idle Lease to Increase Heavy Oil Recovery through Application of Conventional Steam Drive Technology in a Low Dip Slope and Basin Reservoir in the Midway-Sunset Field, San Jaoquin Basin, California  

SciTech Connect

A previously idle portion of the Midway-Sunset field, the ARCO Western Energy Pru Fee property, is being brought back into commercial production through tight integration of geologic characterization, geostatistical modeling, reservoir simulation, and petroleum engineering. This property, shut-in over a decade ago as economically marginal using conventional cyclic steaming methods, has a 200-300 foot thick oil column in the Monarch Sand. However, the sand lacks effective steam barriers and has a thick water-saturation zone above the oil-water contact. These factors require an innovative approach to steam flood production design that will balance optimal total oil production against economically viable steam-oil ratios and production rates. The methods used in the Class III demonstration are accessible to most operators in the Midway-Sunset field and could be used to revitalize properties with declining production of heavy oils throughout the region. In January 1997 the project entered its second and main phase with the purpose of demonstrating whether steamflood can be a more effective mode of production of the heavy, viscous oils from the Monarch Sand reservoir than the more conventional cyclic steaming. The objective is not just to produce the pilot site within the Pru Fee property south of Taft, but to test which production parameters optimize total oil recovery at economically acceptable rates of production and production costs.

Why solar oil shale retorting produces more oil  

DOE Green Energy (OSTI)

A solar oil shale retorting process may produce higher oil yield than conventional processing. High oil yield is obtained for three reasons: oil carbonization inside of the shale is reduced, oil cracking outside of the shale is reduced, and oil oxidation is essentially eliminated. Unique capabilities of focused solar energy produce these advantages. An increase in yield will reduce the cost of mining and shale transportation per barrel of oil produced. These cost reductions may justify the increased processing costs that will probably be associated with solar oil shale retorting.

Foam and emulsion effects on gas driven oil recovery  

SciTech Connect

The aim of this research was to investigate the gas mobility reducing effects that a gas driven surfactant slug has on enhanced oil recovery (EOR). Three chemically similar surfactants whose properties graded from foaming agent to emulsifying agent were used to study the effects that foam and emulsion formation have on enhanced oil recovery in an unconsolidated Ottawa sand model at room temperature. Both the foam lamellae and the emulsion droplets act to reduce the mobility of the injected gas in the swept zone, thus increasing the vertical sweep efficiency. Shell's Enordet series of alcohol ethoxylate surfactants were used in the study at three different concentrations of, 0.01%, 0.03% and 0.100% (wt.). The experimental procedure consisted of displacing oil from a porous medium at residual water saturation by injecting carbon dioxide, followed first by the injection of a 0.20 pore volume slug of surfactant solution, then by carbon dioxide gas at low pressure. Measurements were made of the cumulative produced gas and liquids. Performance differences between different surfactants are small but consistent. Combining the foam and emulsion mechanisms seems to lead to more efficient oil recovery than either mechanism alone. 33 refs., 14 figs., 3 tabs.

SOLVENT-BASED ENHANCED OIL RECOVERY PROCESSES TO DEVELOP WEST SAK ALASKA NORTH SLOPE HEAVY OIL RESOURCES  

SciTech Connect

A one-year research program is conducted to evaluate the feasibility of applying solvent-based enhanced oil recovery processes to develop West Sak and Ugnu heavy oil resources found on the Alaska North Slope (ANS). The project objective is to conduct research to develop technology to produce and market the 300-3000 cp oil in the West Sak and Ugnu sands. During the first phase of the research, background information was collected, and experimental and numerical studies of vapor extraction process (VAPEX) in West Sak and Ugnu are conducted. The experimental study is designed to foster understanding of the processes governing vapor chamber formation and growth, and to optimize oil recovery. A specially designed core-holder and a computed tomography (CT) scanner was used to measure the in-situ distribution of phases. Numerical simulation study of VAPEX was initiated during the first year. The numerical work completed during this period includes setting up a numerical model and using the analog data to simulate lab experiments of the VAPEX process. The goal was to understand the mechanisms governing the VAPEX process. Additional work is recommended to expand the VAPEX numerical study using actual field data obtained from Alaska North Slope.

Refining of shale oil  

DOE Green Energy (OSTI)

The refining of shale oil is reviewed to assess the current state-of-the-art, especially as to the avaiability of technology suitable for operation on a commercial scale. Oil shale retorting processes as they affect the quality of the crude shale oil for refining, exploratory research on the character and refining of shale oil, and other published refining background leading to the present status are discussed. The initial refining of shale oil requires the removal of a large concentration of nitrogen, an added step not required for typical petroleum crude oils, and recently published estimates show that the total cost of refining will be high. Specific technoloy is reported by industry to be technically proven and available for commercial-scale refining. Although the refining will be more costly than that of petroleum, the viability of a shale oil industry will also be affected greatly by the technology and costs of producing the crude shale oil, environmental costs, and future price and tax treatment, and these are outside the scope of this study of refining.

The evaluation of waterfrac technology in low-permeability gas sands in the East Texas basin  

E-Print Network (OSTI)

The petroleum engineering literature clearly shows that large proppant volumes and concentrations are required to effectively stimulate low-permeability gas sands. To pump large proppant concentrations, one must use a viscous fluid. However, many operators believe that low-viscosity, low-proppant concentration fracture stimulation treatments known as ??waterfracs?? produce comparable stimulation results in low-permeability gas sands and are preferred because they are less expensive than gelled fracture treatments. This study evaluates fracture stimulation technology in tight gas sands by using case histories found in the petroleum engineering literature and by using a comparison of the performance of wells stimulated with different treatment sizes in the Cotton Valley sands of the East Texas basin. This study shows that large proppant volumes and viscous fluids are necessary to optimally stimulate tight gas sand reservoirs. When large proppant volumes and viscous fluids are not successful in stimulating tight sands, it is typically because the fracture fluids have not been optimal for the reservoir conditions. This study shows that waterfracs do produce comparable results to conventional large treatments in the Cotton Valley sands of the East Texas basin, but we believe it is because the conventional treatments have not been optimized. This is most likely because the fluids used in conventional treatments are not appropriate or have not been used appropriately for Cotton Valley conditions.

Heavy crude oil recovery  

SciTech Connect

The oil crisis of the past decade has focused most of the attention and effort of researchers on crude oil resources, which are accepted as unrecoverable using known technology. World reserves are estimated to be 600-1000 billion metric tons, and with present technology 160 billion tons of this total can be recovered. This book is devoted to the discussion of Enhanced Oil Recovery (EOR) techniques, their mechanism and applicability to heavy oil reservoirs. The book also discusses some field results. The use of numerical simulators has become important, in addition to laboratory research, in analysing the applicability of oil recovery processes, and for this reason the last section of the book is devoted to simulators used in EOR research.

Corrosivity Of Pyrolysis Oils  

SciTech Connect

Pyrolysis oils from several sources have been analyzed and used in corrosion studies which have consisted of exposing corrosion coupons and stress corrosion cracking U-bend samples. The chemical analyses have identified the carboxylic acid compounds as well as the other organic components which are primarily aromatic hydrocarbons. The corrosion studies have shown that raw pyrolysis oil is very corrosive to carbon steel and other alloys with relatively low chromium content. Stress corrosion cracking samples of carbon steel and several low alloy steels developed through-wall cracks after a few hundred hours of exposure at 50 C. Thermochemical processing of biomass can produce solid, liquid and/or gaseous products depending on the temperature and exposure time used for processing. The liquid product, known as pyrolysis oil or bio-oil, as produced contains a significant amount of oxygen, primarily as components of water, carboxylic acids, phenols, ketones and aldehydes. As a result of these constituents, these oils are generally quite acidic with a Total Acid Number (TAN) that can be around 100. Because of this acidity, bio-oil is reported to be corrosive to many common structural materials. Despite this corrosive nature, these oils have the potential to replace some imported petroleum. If the more acidic components can be removed from this bio-oil, it is expected that the oil could be blended with crude oil and then processed in existing petroleum refineries. The refinery products could be transported using customary routes - pipelines, barges, tanker trucks and rail cars - without a need for modification of existing hardware or construction of new infrastructure components - a feature not shared by ethanol.

Petroleum geology of heavy oil in the Oriente basin of Ecuador: Exploration and exploitation challenge for the 1990s  

Science Conference Proceedings (OSTI)

Published Ecuadorian government forecasts suggest that Oriente basin light oil (21-32{degree} API) production may start to decline in the early to mid-1990s. To maintain stabilized production into the next century, heavy oil reserves (10-20{degree} API) will have to be aggressively exploited. The Oriente's undeveloped proven plus probable heavy reserves are substantial and are expected to exceed 0.5 billion bbl. A recent discovery made by Conoc Ecuador Ltd., operator of Block 16 for a group which consists of O.P.I.C., Maxus, Nomeco, Murphy and Canam, is a good model for future exploration and exploitation of heavy oil in the remote eastern regions of the basin. Amo-1 tested a low-relief anticline (less than 100 ft vertical closure) and encountered 10-20{degree} API oil in five Cretaceous sandstone reservoirs (8,000-10,000 ft depth). Cumulative test production was 1,062 BOPD. Subsequent drilling along the trend resulted in three additional discoveries. The Cretaceous sands were transported from the Brazilian shield by the westward flowing proto-Amazon River and were deposited in fluviodeltaic, tidal, and high-energy marginal marine environments. Air permeabilities are high and geometric mean values approaching several darcies. Porosities average 18-22% in generally well-consolidated sands. The heavy oils are the result of mild biodegradation and/or expulsion from a thermally immature source. Oil-to-oil correlations suggest that all of the basin oils have the same or similar origin, probably marine calcareous shales of the Cretaceous Napo formation. The Block 16 project will provide a major step toward the strategic exploitation of the Oriente basin's heavy oil reserves, when it comes on stream in the early 1990s.

Excess Foundry Sand Characterization and Experimental Investigation in Controlled Low-Strength Material and Hot-Mixing Asphalt  

SciTech Connect

This report provides technical data regarding the reuse of excess foundry sand. The report addresses three topics: a statistically sound evaluation of the characterization of foundry sand, a laboratory investigation to qualify excess foundry sand as a major component in controlled low-strength material (CLSM), and the identification of the best methods for using foundry sand as a replacement for natural aggregates for construction purposes, specifically in asphalt paving materials. The survival analysis statistical technique was used to characterize foundry sand over a full spectrum of general chemical parameters, metallic elements, and organic compounds regarding bulk analysis and leachate characterization. Not limited to characterization and environmental impact, foundry sand was evaluated by factor analyses, which contributes to proper selection of factor and maximization of the reuse marketplace for foundry sand. Regarding the integration of foundry sand into CLSM, excavatable CLSM and structural CLSM containing different types of excess foundry sands were investigated through laboratory experiments. Foundry sand was approved to constitute a major component in CLSM. Regarding the integration of foundry sand into asphalt paving materials, the optimum asphalt content was determined for each mixture, as well as the bulk density, maximum density, asphalt absorption, and air voids at Nini, Ndes, and Nmax. It was found that foundry sands can be used as an aggregate in hot-mix asphalt production, but each sand should be evaluated individually. Foundry sands tend to lower the strength of mixtures and also may make them more susceptible to moisture damage. Finally, traditional anti-stripping additives may decrease the moisture sensitivity of a mixture containing foundry sand, but not to the level allowed by most highway agencies.

EXPERIMENTAL AND THEORETICAL DETERMINATION OF HEAVY OIL VISCOSITY UNDER RESERVOIR CONDITIONS  

Science Conference Proceedings (OSTI)

The USA deposits of heavy oils and tar sands contain significant energy reserves. Thermal methods, particularly steam drive and steam soak, are used to recover heavy oils and bitumen. Thermal methods rely on several displacement mechanisms to recover oil, but the most important is the reduction of crude viscosity with increasing temperature. The main objective of this research is to propose a simple procedure to predict heavy oil viscosity at reservoir conditions as a function of easily determined physical properties. This procedure will avoid costly experimental testing and reduce uncertainty in designing thermal recovery processes. First, we reviewed critically the existing literature choosing the most promising models for viscosity determination. Then, we modified an existing viscosity correlation, based on the corresponding states principle in order to fit more than two thousand commercial viscosity data. We collected data for compositional and black oil samples (absence of compositional data). The data were screened for inconsistencies resulting from experimental error. A procedure based on the monotonic increase or decrease of key variables was implemented to carry out the screening process. The modified equation was used to calculate the viscosity of several oil samples where compositional data were available. Finally, a simple procedure was proposed to calculate black oil viscosity from common experimental information such as, boiling point, API gravity and molecular weight.

Scales of geologic reservoir description for engineering applications: North Sea oil field example  

SciTech Connect

A consequence of the increased interaction between geologists and engineers in resolving reservoir problems has been an awareness on the part of geologists of the need to vary the scale of their geologic description according to particular engineering applications. Conventional geological descriptions are normally too detailed for reservoir engineering simulations and often are not in an appropriate form for relating to reservoir performance. An example is presented of two scales of description of a North Sea oil field for two different applications. The field is a Tertiary submarine slope-fan deposit consisting of thick unconsolidated channel sand facies, a lobe sand facies, and a slope claystone facies, all arranged into 12 stratigraphic units and several subunits. Permeability of the channel sands is about twice that of lobe sands, demonstrating a facies control on reservoir quality. For the purpose of calculating reservoir volumetrics, it was possible to scale up the stratigraphy, by combining similar stratigraphic units, into a simple four-layer reservoir model. Average porosity and permeability vary among the layers in this geologically based model. For the purpose of improving understanding of the reservoir, a more complex flow unit model was developed according to geological and petrophysical properties that would influence the flow of fluids in the reservoir. This model is partly based upon sedimentary facies distribution, but differs from a geologic facies model and is in a more suitable form for relating to reservoir performance.

Design and Implementation of Energized Fracture Treatment in Tight Gas Sands  

SciTech Connect

Hydraulic fracturing is essential for producing gas and oil at an economic rate from low permeability sands. Most fracturing treatments use water and polymers with a gelling agent as a fracturing fluid. The water is held in the small pore spaces by capillary pressure and is not recovered when drawdown pressures are low. The un-recovered water leaves a water saturated zone around the fracture face that stops the flow of gas into the fracture. This is a particularly acute problem in low permeability formations where capillary pressures are high. Depletion (lower reservoir pressures) causes a limitation on the drawdown pressure that can be applied. A hydraulic fracturing process can be energized by the addition of a compressible, sometimes soluble, gas phase into the treatment fluid. When the well is produced, the energized fluid expands and gas comes out of solution. Energizing the fluid creates high gas saturation in the invaded zone, thereby facilitating gas flowback. A new compositional hydraulic fracturing model has been created (EFRAC). This is the first model to include changes in composition, temperature, and phase behavior of the fluid inside the fracture. An equation of state is used to evaluate the phase behavior of the fluid. These compositional effects are coupled with the fluid rheology, proppant transport, and mechanics of fracture growth to create a general model for fracture creation when energized fluids are used. In addition to the fracture propagation model, we have also introduced another new model for hydraulically fractured well productivity. This is the first and only model that takes into account both finite fracture conductivity and damage in the invaded zone in a simple analytical way. EFRAC was successfully used to simulate several fracture treatments in a gas field in South Texas. Based on production estimates, energized fluids may be required when drawdown pressures are smaller than the capillary forces in the formation. For this field, the minimum CO{sub 2} gas quality (volume % of gas) recommended is 30% for moderate differences between fracture and reservoir pressures (2900 psi reservoir, 5300 psi fracture). The minimum quality is reduced to 20% when the difference between pressures is larger, resulting in additional gas expansion in the invaded zone. Inlet fluid temperature, flow rate, and base viscosity did not have a large impact on fracture production. Finally, every stage of the fracturing treatment should be energized with a gas component to ensure high gas saturation in the invaded zone. A second, more general, sensitivity study was conducted. Simulations show that CO{sub 2} outperforms N{sub 2} as a fluid component because it has higher solubility in water at fracturing temperatures and pressures. In fact, all gas components with higher solubility in water will increase the fluid's ability to reduce damage in the invaded zone. Adding methanol to the fracturing solution can increase the solubility of CO{sub 2}. N{sub 2} should only be used if the gas leaks-off either during the creation of the fracture or during closure, resulting in gas going into the invaded zone. Experimental data is needed to determine if the gas phase leaks-off during the creation of the fracture. Simulations show that the bubbles in a fluid traveling across the face of a porous medium are not likely to attach to the surface of the rock, the filter cake, or penetrate far into the porous medium. In summary, this research has created the first compositional fracturing simulator, a useful tool to aid in energized fracture design. We have made several important and original conclusions about the best practices when using energized fluids in tight gas sands. The models and tools presented here may be used in the future to predict behavior of any multi-phase or multi-component fracturing fluid system.

Oil shale data book  

SciTech Connect

The Oil Shale Data Book has been prepared as a part of its work under DOE Management Support and Systems Engineering for the Naval Oil Shale Reserves Predevelopment Plan. The contract calls for the preparation of a Master Development Plan for the Reserves which comprise some 145,000 acres of oil shale lands in Colorado and Utah. The task of defining the development potential of the Reserves required that the resources of the Reserves be well defined, and the shale oil recovery technologies that are potentially compatible with this resource be cataloged. Additionally, processes associated with shale oil recovery like mining, materials handling, beneficiation, upgrading and spent shale disposal have also been cataloged. This book, therefore, provides a ready reference for evaluation of appropriate recovery technologies and associated processes, and should prove to be valuable for many oil shale activities. Technologies that are still in the process of development, like retorting, have been treated in greater detail than those that are commercially mature. Examples of the latter are ore crushing, certain gas clean-up systems, and pipeline transportation. Emphasis has been on documenting available design information such as, maximum module size, operation conditions, yields, utility requirements, outlet gas compositions, shale oil characteristics, etc. Cost information has also been included where available.
