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

SciTech Connect (OSTI)

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 (OSTI)

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.

Policy Analysis of the Canadian Oil Sands Experience  

SciTech Connect (OSTI)

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.

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

SciTech Connect (OSTI)

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.

Recovery of bitumen from oil sand by steam with chemicals  

SciTech Connect (OSTI)

Recently, oil sand bitumen has become the center of attention as a possible oil energy substitute for the future. Until now, the development of oil sand has been performed by surface miing and conventional steam injection, these methods are limited in respect to resource recovery. A more effective method needs to be developed utilizing in situ recovery. In this study, a new attempt is made for the purpose of enhancing the recovery of bitumen from oil sand by adopting the method of injecting high pressure steam and chemicals such as solvents, surfactants, and others.

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...

Aging effects on oil-contaminated Kuwaiti sand  

SciTech Connect (OSTI)

Large quantities of oil-contaminated sands resulted from the destruction of oil wells and the formation of oil lakes in Kuwait at the end of the Gulf Wa/r. A laboratory testing program was carried out to determine the geotechnical properties of this material and the effect of aging on their properties. Tests included direct shear, triaxial, and consolidation tests on clean and contaminated sand at the same relative density. The influence of aging was examined by testing uncontaminated sand after aging for one, three, and six months in natural environmental conditions. The results indicated increased strength and stiffness due to aging and a reduction of the oil content due to evaporation of volatile compounds. The factors that influence the depth of oil penetration in compacted sand columns were also examined including the type of oil, relative density, and the amount of fines.

Geotechnical properties of oil-contaminated Kuwaiti sand  

SciTech Connect (OSTI)

Large quantities of oil-contaminated sands resulted from exploded oil wells, burning oil fires, the destruction of oil storage tanks, and the formation of oil lakes in Kuwait at the end of the Gulf War. An extensive laboratory testing program was carried out to determine the geotechnical characteristics of this material. Testing included basic properties, compaction and permeability tests, and triaxial and consolidation tests on clean and contaminated sand at the same relative density. Contaminated specimens were prepared by mixing the sand with oil in the amount of 6% by weight or less to match field conditions. The influence of the type of oil, and relative density was also investigated by direct shear tests. The results indicated a small reduction in strength and permeability and an increase in compressibility due to contamination. The preferred method of disposal of this material is to use it as a stabilizing material for other projects such as road construction.

The process variables investigated included reactor pressure (11.2--16.7 MPa); reactor temperature (641--712 K) and liquid hourly space velocity (0.19--0.77 h{sup {minus}1}). The hydrogen/oil ratio, 890 m{sup 3} m{sup {minus}3} was fixed in all experiments. A sulphided Ni-Mo on alumina hydrodenitrogenation catalyst was used in these studies. The deactivation of the catalyst, 0.2 {degree}C/day, was monitored by thedecline in the API gravity of the total liquid product with time on-stream at a standard set of conditions. The effect of temperature, WHSV, and pressure on denitrogenation, desulphurization, and metals removalwere studied and apparent kinetic parameters determined. The effect of process variables on residue conversion and Conradson carbon residue reduction were also investigated.

Highly variable oil prices and increasing world demand for oil have led producers to look for alternative sources of transportation fuel. Two popular alternatives are oil sands (aka tar sands) and oil shale. However, obtaining usable oil from oil sands or oil shale is more capital-intensive and more expensive than obtaining oil from conventional reserves. At what price of oil do these alternatives become cost-effective? Oil Sands Oil sands are a mixture of sand, water, clay and heavy, viscous oil called bitumen. The largest known deposits of oil sands are in Alberta, Canada, and the Orinoco Oil

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

SciTech Connect (OSTI)

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.

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

SciTech Connect (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.  

SciTech Connect (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.

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

SciTech Connect (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 (OSTI)

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.

Temperature effects on oil-water relative permeabilities for unconsolidated sands  

SciTech Connect (OSTI)

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.

Analysis of techniques for predicting viscosity of heavy oil and tar sand bitumen  

SciTech Connect (OSTI)

Thermal recovery methods are generally employed for recovering heavy oil and tar sand bitumen. These methods rely on reduction of oil viscosity by application of heat as one of the primary mechanisms of oil recovery. Therefore, design and performance prediction of the thermal recovery methods require adequate prediction of oil viscosity as a function of temperature. In this paper, several commonly used temperature-viscosity correlations are analyzed to evaluate their ability to correctly predict heavy oil and bitumen viscosity as a function of temperature. The analysis showed that Ali and Standing`s correlations gave satisfactory results in most cases when properly applied. Guidelines are provided for their application. None of the correlations, however, performed satisfactorily with very heavy oils at low temperatures.

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

SciTech Connect (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)

Pore Scale Analysis of Oil Shale/Sands Pyrolysis  

SciTech Connect (OSTI)

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.

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

SciTech Connect (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.

A process for removing oil from coal fines that have been agglomerated or blended with heavy oil comprises the steps of heating the coal fines to temperatures over 350.degree. C. up to 450.degree. C. in an inert atmosphere, such as steam or nitrogen, to convert some of the heavy oil to lighter, and distilling and collecting the lighter oils. The pressure at which the process is carried out can be from atmospheric to 100 atmospheres. A hydrogen donor can be added to the oil prior to deposition on the coal surface to increase the yield of distillable oil.

SOVENT BASED ENHANCED OIL RECOVERY FOR IN-SITU UPGRADING OF HEAVY OIL SANDS  

SciTech Connect (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 CO2. The model also incorporated the characteristic of a highly varying CO2 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.

Temperature effects on oil-water relative permeabilities for unconsolidated sands  

SciTech Connect (OSTI)

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 (S/sub or/) and oil and water relative permeabilities. The temperature sensitivity study of relative permeabilities was conducted in two parts. The first was to investigate changes in S/sub or/ with temperature where the cores were 100% saturated with oil at the start of the waterflood. Runs were terminated when the water-cut exceeded 99.8%. For these experiments, S/sub or/ decreased from 0.31 at 70/sup 0/F to 0.09 at 250/sup 0/F. The second part continued the floods for a longer time until the water-cut was virtually 100%. Under these conditions, little change in S/sub or/ was observed with temperature; (0.11 at 70/sup 0/F and 0.085 at 186/sup 0/F). Temperature effects on irreducible water saturations were studied. A small increase in irreducibile water saturation was observed upon increasing the temperature. However, the same magnitude of change was observed by changing the flowrate. Upon increasing the oil flowrate, immediate water production was observed from the core indicating a change in the capillary end effect. By comparing the change in irreducible water saturation with rate and temperature, it was determined that the change was caused mainly by a change in the viscous force across the core. A study on viscous instabilities was also performed. This verified the existence of viscous fingers during waterflooding. It was also observed that tubing volume after the core could cause fingering, resulting in lower apparent breakthrough oil recoveries.

Supercritical fluid extraction of bitumen free solids separated from Athabasca oil sand feed and hot water process tailings pond sludge  

SciTech Connect (OSTI)

The presence of strongly bound organic matter (SOM), in association with certain solids fractions, causes serious problems in the processability of Athabasca oil sands as well as in the settling and compaction of hot water process tailing pond sludge. It has been demonstrated that a substantial amount of this SOM can be separated from oil sands feed and sludge solids, after removal of bitumen by toluene, using a supercritical fluid extraction (SFE) method. The extracted material is soluble in common organic solvents which allows a direct comparison, between the SOM separated from oil sands and sludges, from the point of view of both gross analysis of the major compound types and detailed analysis of chemical structures.

Factors that affect the degradation of naphthenic acids in oil sands wastewater by indigenous microbial communities  

SciTech Connect (OSTI)

The acute toxicity of wastewater generated during the extraction of bitumen from oil sands is believed to be due to naphthenic acids (NAs). To determine the factors that affect the rate of degradation of representative NAs in microcosms containing wastewater and the acute toxicity of treated and untreated wastewater, the effects of temperature, dissolved oxygen concentration, and phosphate addition on the rate of {sup 14}CO{sub 2} release form two representative naphthenic acid substrates, (linear) U-{sup 14}C-palmitic acid (PA) and (bicyclic) decahydro-2-naphthoic acid-8-{sup 14}C (DHNA), were monitored. Tailings pond water (TPW) contained microorganisms well adapted to mineralizing both PA and DHNA:PA was degraded more quickly (10--15% in 4 weeks) compared to DHNA (2--4% in 8 weeks). On addition of phosphate, the rate of NA degradation increased up to twofold in the first 4 weeks, with a concurrent increase in the rate of oxygen consumption by oil sands TPW. The degradation rate then declined to levels equivalent to those measured in flasks without phosphate. The observed plateau was not due to phosphate limitation. Decreases in either the dissolved oxygen concentration or the temperature reduced the rate. Phosphate addition also significantly decreased the acute toxicity of TPW to fathead minnows. In contrast, Microtox{reg_sign} analyses showed no reduction in the toxicity of treated or untreated TPW after incubation for up to 8 weeks at 15 C.

Perch population assessment in lakes reclaimed using oil-sands derived material  

SciTech Connect (OSTI)

The mining and extraction of petroleum products from oil-sands involves large areas of land and produces enormous volumes of tailings. One possible land reclamation option is to incorporate fine-tailings material into the bottoms of constructed lakes capped with natural surface water. The wet landscape method represents potential risk to aquatic biota-naphthenic acids and PAHs elute from pore water contained in the fine-tailings substrate. In spring 1995 yellow perch were stocked into a large-scale (5ha) experimental pond that consisted of fine-tailings capped with natural water as well as into two other reclaimed ponds that were constructed with oil-sands overburden material. Prior to stocking of perch, ponds had colonized with cyprinids, macrophytes and benthic invertebrates over a two year period. Perch were sampled in fall 1995 for age, condition factor, liver size, gonad size, fecundity, stomach contents, liver mixed-function oxygenase activity (MFO), bile PAH metabolites and plasma steroid hormones. When compared to the source lake, perch in the DP did not show reduced reproductive potential. Perch in all of the reclaimed ponds demonstrated exposure to organic compounds as indicated by marginally induced MFO activity and increased liver size. Exposure to naphthenates and PAHs in water as well as ecological environmental factors will be discussed.

Libya, Algeria and Egypt: crude oil potential from known deposits  

SciTech Connect (OSTI)

An analysis is presented of the discovered crude oil resources, reserves, and estimated annual production from known fields of the Republics of Libya, Algeria, and Egypt. Proved reserves are defined as the remaining producible oil as of a specified date under operating practice in effect at that time and include estimated recoverable oil in undrilled portions of a given structure or structures. Also included in the proved reserve category are the estimated indicated additional volumes of recoverable oil from the entire oil reservoir where fluid injection programs have been started in a portion, or portions, of the reservoir. The indicated additional reserves (probable reserves) reported herein are the volumes of crude oil that might be obtained with the installation of secondary recovery or pressure maintenance operations in reservoirs where none have been previously installed. The sum of cumulative production, proved reserves, and probable reserves is defined as the ultimate oil recovery from known deposits; and resources are defined as the original oil in place (OOIP). An assessment was made of the availability of crude oil under three assumed sustained production rates for each country; an assessment was also made of each country's capability of sustaining production at, or near, the 1980 rates assuming different limiting reserve to production ratios. Also included is an estimate of the potential maximum producing capability from known deposits that might be obtained from known accumulations under certain assumptions, using a simple time series approach. The theoretical maximum oil production capability from known fields at any time is the maximum deliverability rate assuming there are no equipment, investment, market, or political constraints.

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...

Determining the ecological viability of constructed wetlands for the treatment of oil sands wastewater  

SciTech Connect (OSTI)

To determine the conditions for optimal degradation of naphthenic acids (C{sub n}H{sub 2n+z}O{sub 2}), the most toxic component of oil sands wastewater, the authors have monitored the mineralization of 2 representative naphthenic acids (NA), U-{sup 14}C-palmitic acid (linear, Z = 0) and 8-{sup 14}C-decahydro-2-naphthoic acid (bicyclic, Z = {minus}4) under varying conditions of temperature, phosphate and oxygen. The radiolabeled NA was added to biometer flasks containing wastewater {+-} amendments and evolved {sup 14}C-CO{sub 2} was trapped in a side arm and counted by LSC. The results indicate that low temperature (5 C) and anaerobiasis greatly inhibited NA degradation over the four week incubation period. Addition of phosphate (as buffered KP{sub i}) significantly increased {sup 14}C-CO{sub 2} production for both Z = 0 and Z = {minus}4 compounds; however, the subsequent high microbial growth rates also decreased PO{sub 2} which limited NA mineralization. Effluent toxicity was monitored at week 0 and week 4 using Microtox and fathead minnow tests. Although there was increased survival of fathead minnows in the phosphate-amended effluent, the IC{sub 20} values of the Microtox assay showed no improvement in either the phosphate-treated or untreated effluents. These results show that naphthenic acid analogues are readily degraded by indigenous microorganisms in oil sands wastewater and that phosphate addition accelerated the mineralization of these compounds if PO{sub 2} remained high.

Turbine fuels from tar-sands bitumen and heavy oil. Part 2. Phase II. Laboratory sample production. Interim report, 1 October 1983-31 October 1985  

SciTech Connect (OSTI)

The conversion of domestic tar-sands bitumens or heavy crude oils into aviation turbine fuels was studied in small scale equipment to demonstrate the process scheme consisting of hydrovisbreaking the bitumen or crude residuum follwed by catalytic hydrotreating or hydrocracking of the resultant naphtha or distillate fractions. Four different feedstocks were employed; two were bitumens (from Kentucky or Utah) and two were heavy crudes from California. Significant operating parameters were examined for each process step. Prototype naphtha and kerosene-type fuel samples compared well with JP-4 and JP-8 specifications, although fuels prepared from Utah bitumen (Sunnyside deposit) were deficient in freeze point. Initiation of Phase III, pilot-plant-scale evaluation of the process is recommended.

Assessment of fish health effects resulting from exposure to oil sands wastewater  

SciTech Connect (OSTI)

The objective of this study was to determine if oil sands wastewater had an effect on the general health and condition of hatchery raised rainbow trout (200 to 400 g). Effects were assessed based on a battery of physiological and biochemical indices and the physical condition of the fish. The trout were exposed to tailings water in the field and in a flow through system under laboratory conditions. The field tests were conducted in 1992 and 1993 in experimental ponds at Syncrude which contained fine tails covered with surface water, fine tails covered with tailings water, and a surface water control pond. The laboratory treatments included Mildred Lake tailings water, dyke drainage water, fractionated tailings pond water (acid fraction containing naphthenic acids), sodium naphthenate, recycle water from Suncor`s tailings pond, and a laboratory control. All body condition factors and blood parameters were normal in the field and laboratory exposed fish and there were no apparent differences between the fish exposed to the tailings water and controls.

Demineralization of petroleum cokes and fly ash samples obtained from the upgrading of Athabasca oil sands bitumen  

SciTech Connect (OSTI)

Today's commercially proved technology to recover oil from the Athabasca oil sands, as practiced by Suncor and Syncrude, involves two major operations, namely: separation of the bitumen from the sand and upgrading of the bitumen to refinery oil. Significant amounts of petroleum coke are produced during the bitumen upgrading process. Suncor burns the bulk of its petroleum coke in boilers to fulfill the energy requirements of the entire operation, still meeting government regulations restricting the amount of sulfur dioxide that can be released to the environment. In contrast, Syncrude is able to burn only 20% of its coke production because of high sulphur dioxide emissions from elsewhere in its operations. The boiler ash (Fly ash) which contains appreciable amounts of metals, such as vanadium, nickel, titianium, iron, aluminum and other elements, is collected in the boiler hoppers and cyclones of the petroleum coke fired steam generation plants. There has been relatively little effort made towards the understanding of the chemical or physical nature of these materials. Knowledge of the physico-chemical properties of these materials will be helpful in assessing their beneficiation and potential use as fuel or metallurigcal coke and the feasibility of extracting some metals, especially Ni and V. In this communication the authors report studies of acid demineralization as a means of reducing ash content of these materials for /sup 13/C NMR spectroscopic investigations.

Yellow perch embryo-larval survival and growth in surface waters associated with oil-sands mining  

SciTech Connect (OSTI)

As part of their land reclamation strategy, Syncrude Canada Ltd. is currently developing environmentally acceptable tailings disposal methods. Fine tailings, a suspension of clay and residual bitumen, is the waste product from oil sands extraction. Fine-tailings contain naphthenic acids, a group of saturated aliphatic and alicyclic carboxylic acids, which occur naturally in petroleum and are partly responsible for the toxicity of process water. The wet landscape method involves covering fine tails with a layer of water such that a self-sustaining ecosystem can be established. A 5 ha demonstration pond with a bottom of fine-tailings was constructed and stocked with yellow perch for experimental purposes. Two other reclaimed ponds formed with oil-sands overburden material were also stocked with perch. Adult perch sampled in the fall of 1995 from the experimental and reclaimed ponds exhibited a 2-fold induction of MFO activity compared to the source lake; indicating organic compound exposure. Perch from one of the reclaimed ponds showed significantly reduced circulating reproductive hormone levels, gonad size and smaller ovarian follicles. Reproductive parameters were not different between the source lake and the remaining ponds. Paired lab and field experiments were conducted to determine if contaminants present would be detrimental to egg viability and development of larvae either through direct exposure of spawned eggs or indirectly by effecting oogenesis. An early life stage toxicity test was also performed using commercially available naphthenic acid standard. Endpoints measured were percent fertilization, percent hatch, mortality, deformities, timing of developmental periods and larval growth.

A New Stochastic Modeling of 3-D Mud Drapes Inside Point Bar Sands in Meandering River Deposits  

SciTech Connect (OSTI)

The environment of major sediments of eastern China oilfields is a meandering river where mud drapes inside point bar sand occur and are recognized as important factors for underground fluid flow and distribution of the remaining oil. The present detailed architectural analysis, and the related mud drapes' modeling inside a point bar, is practical work to enhance oil recovery. This paper illustrates a new stochastic modeling of mud drapes inside point bars. The method is a hierarchical strategy and composed of three nested steps. Firstly, the model of meandering channel bodies is established using the Fluvsim method. Each channel centerline obtained from the Fluvsim is preserved for the next simulation. Secondly, the curvature ratios of each meandering river at various positions are calculated to determine the occurrence of each point bar. The abandoned channel is used to characterize the geometry of each defined point bar. Finally, mud drapes inside each point bar are predicted through random sampling of various parameters, such as number, horizontal intervals, dip angle, and extended distance of mud drapes. A dataset, collected from a reservoir in the Shengli oilfield of China, was used to illustrate the mud drapes' building procedure proposed in this paper. The results show that the inner architectural elements of the meandering river are depicted fairly well in the model. More importantly, the high prediction precision from the cross validation of five drilled wells shows the practical value and significance of the proposed method.

Interactions between nitrifying bacteria and hydrocarbon-degrading bacteria during detoxification of oil sands process affected water  

SciTech Connect (OSTI)

Large quantities of process water are produced during the extraction of bitumen from oil sands by the Syncrude and Suncor operations in northern Alberta. Freshly produced tailings water is acutely toxic, but it has been shown to slowly detoxify over time. As detoxification proceeds, there is also a precipitous decrease in ammonia concentrations. The present study examines these two microbially-mediated processes in relation to levels of bacteria and toxicants in mixtures of fresh and aged (detoxified) tailings water. Detoxification of tailings water was greatly accelerated when equal volumes of fresh and detoxified (natural aging for one year) tailings water were mixed. Addition of phosphorus further stimulated detoxification, causing levels of ammonia and naphthenic acids (toxic organic acids leached during bitumen extraction) to decrease to those of detoxified water within two months. Such changes were not observed when phosphorus was not added, or when it was added to less diluted (10-.1 or 3-.1) fresh tailings water. Populations of nitrifying bacteria and naphthenic acid degraders increased markedly in the phosphorus-amended mixtures, but not in its absence. Addition of CS{sub 2} (a specific inhibitor of nitrification) to these mixtures prevented ammonia oxidation. Surprisingly, it also prevented the increase in naphthenic acid-degraders and retarded the loss of naphthenic acids. These results suggest the existence of interactions in fresh tailings water between nitrifying bacteria, naphthenic acid degraders and toxicants. The activity of naphthenic acid-degraders apparently remains low until ammonia is oxidized, whereas that of nitrifying bacteria remains low until concentrations of naphthenic acids or other toxicants decrease below some threshold level. Understanding these interactions may lead to more efficient and effective processes to detoxify oil sands process water.

Combustion turbine deposition observations from residual and simulated residual oil studies  

SciTech Connect (OSTI)

Burning residual oil in utility combustion turbines and the consequent deposition on blades and vanes may adversely affect reliability and operation. Corrosion and deposition data for combustion turbine materials have been obtained through dynamic testing in pressurized passages. The deposition produced by the 1900/sup 0/F (1038/sup 0/C) combustion gases from a simulated and a real residual oil on cooled Udimet 500 surfaces is described. Higher deposition rates for the doped fuel than for the real residual oil raised questions of whether true simulation with this approach can be achieved. Particles 4-8..mu.. m in diameter predominated in the gas stream, with some fraction in the 0.1-12 ..mu.. m range. Deposition rates seemed to be influenced by thermophoretic delivery of small molten particles, tentatively identified as magnesium pyro and metavanadates and free vanadium pentoxide, which may act to bond the larger solid particles arriving by inertial impaction to turbine surfaces. Estimated maintenance intervals for current utility turbines operating with washed and treated residual oil agreed well with field experience.

Stratigraphy, coal occurrence, and depositional history of the Paleocene Fort Union Formation, Sand Wash basin, northwestern Colorado  

SciTech Connect (OSTI)

The Fort Union Formation in the Sand Wash basin is divided into the massive Cretaceous and Tertiary (K/T) sandstone unit, lower coal-bearing unit, gray-green mudstone unit, basin sandy unit, and upper shaly unit. Lithofacies and coal-occurrence maps of the stratigraphic units indicate that sandstone bodies and coal beds occur along south-north oriented, intermontane fluvial systems. Net-sandstone-thickness trends of the massive K/T sandstone unit reveal laterally extensive channel-fill sandstones formed in north-flowing fluvial systems. The massive K/T sandstone unit's dominant source was in the Sawatch Range. Sandstones within the lower coal-bearing unit consist of similar north-flowing fluvial systems, but they are laterally discontinuous and have several tectonically active source areas, including the Uinta and Sierra Madre-Park uplifts, and Sawatch Range. Coal-occurrence maps of the lower coal-bearing unit indicate that maximum coal-bed thicknesses are greatest along the south-north-oriented fluvial axes. Coal beds thin and split to the east and west, confirming a direct relation between the position of thick, fluvial-sandstone bodies, which form a stable platform for peat accumulation, and the location of the thick coal beds. Above the lower coal-bearing unit, the gray-green mudstone unit forms north-trending belts centered R91W and R100W. The gray-green mudstone thins to the north and into the basin center and probably is lacustrine in origin, reflecting tectonic quiescence and cessation of coarse clastic sedimentation. The basin sandy unit is best developed in the central parts of the basin, where its fluvial depositional axis is oriented south-north. The upper shaly unit directly overlies the basin sandy unit and includes a thin Cherokee coal zone. The upper shaly unit has variable thicknesses due to erosion at the base of the Wasatch Formation and lateral facies changes.

History of development and depositional environment and upper Cherokee Prue Sand, Custer and Roger Mills counties, Oklahoma  

SciTech Connect (OSTI)

In western Oklahoma the uppermost sand member of the Cherokee Group, the True sand, was first drilled and found productive in two discoveries, completed in 1980, in west-central Custer County and in central Roger Mills County, Oklahoma. For 1 1/2 to 2 years these two discoveries, some 18 mi (29 km) apart, were thought to be stratigraphic equivalents of two separate sand bodies occurring parallel to the classic northwest-southeast-trending systems of the Anadarko basin. At present, some 40 productive wells will ultimately produce more than 100 bcf of gas and 3 million bbl of condensate from an average depth of 11,500 ft (3500 m). Sand porosities range from 3 to 18% with most producing wells having porosities in the 12 to 15% range. Because Prue sand is slightly overpressured (a pressure gradient of .53 psi/foot), the reserves are generally better than normal-pressured wells at this depth. The sand body is over 40 mi (64 km) in length, 1 to 1.5 mi (1.6 to 2.4 km) wide, and 60 ft (18 m) thick. Study of the core shows the interval to grade from a medium to fine-grained sand, highly laminated and cross-bedded with black shale, to a slightly coarser grained nonstructured interval and back into a highly laminated cross-bedded sandy black shale interval. The interval is topped by a 10 ft (3 m) thick black shale layer that is a predominant bed throughout the whole area. These conclusions have implications that may assist in the exploration of other Pennsylvanian sands in this area.

Evaluation of Wax Deposition and Its Control During Production of Alaska North Slope Oils  

SciTech Connect (OSTI)

Due to increasing oil demand, oil companies are moving into arctic environments and deep-water areas for oil production. In these regions of lower temperatures, wax deposits begin to form when the temperature in the wellbore falls below wax appearance temperature (WAT). This condition leads to reduced production rates and larger pressure drops. Wax problems in production wells are very costly due to production down time for removal of wax. Therefore, it is necessary to develop a solution to wax deposition. In order to develop a solution to wax deposition, it is essential to characterize the crude oil and study phase behavior properties. The main objective of this project was to characterize Alaskan North Slope crude oil and study the phase behavior, which was further used to develop a dynamic wax deposition model. This report summarizes the results of the various experimental studies. The subtasks completed during this study include measurement of density, molecular weight, viscosity, pour point, wax appearance temperature, wax content, rate of wax deposition using cold finger, compositional characterization of crude oil and wax obtained from wax content, gas-oil ratio, and phase behavior experiments including constant composition expansion and differential liberation. Also, included in this report is the development of a thermodynamic model to predict wax precipitation. From the experimental study of wax appearance temperature, it was found that wax can start to precipitate at temperatures as high as 40.6 C. The WAT obtained from cross-polar microscopy and viscometry was compared, and it was discovered that WAT from viscometry is overestimated. From the pour point experiment it was found that crude oil can cease to flow at a temperature of 12 C. From the experimental results of wax content, it is evident that the wax content in Alaskan North Slope crude oil can be as high as 28.57%. The highest gas-oil ratio for a live oil sample was observed to be 619.26 SCF/STB. The bubblepoint pressure for live oil samples varied between 1600 psi and 2100 psi. Wax precipitation is one of the most important phenomena in wax deposition and, hence, needs to be modeled. There are various models present in the literature. Won's model, which considers the wax phase as a non-ideal solution, and Pedersen's model, which considers the wax phase as an ideal solution, were compared. Comparison indicated that Pedersen's model gives better results, but the assumption of wax phase as an ideal solution is not realistic. Hence, Won's model was modified to consider different precipitation characteristics of the various constituents in the hydrocarbon fraction. The results obtained from the modified Won's model were compared with existing models, and it was found that predictions from the modified model are encouraging.

Tar sand  

SciTech Connect (OSTI)

Research on tar sand is briefly discussed. The research program supported by the US Department of Energy (DOE) includes a variety of surface extraction schemes. The University of Utah has process development units (PDU) employing fluidized bed, hot, water-assisted, and fluidized-bed/heat-pipe, coupled combustor technology. Considerable process variable test data have been gathered on these systems: (1) a rotary kiln unit has been built recently; (2) solvent extraction processing is being examined; and (3) an advanced hydrogenation upgrading scheme (hydropyrolysis) has been developed. The University of Arkansas, in collaboration with Diversified Petroleum, Inc., has been working on a fatty acid, solvent extraction process. Oleic acid is the solvent/surfactant. Solvent is recovered by adjusting processing fluid concentrations to separate without expensive operations. Western Research Institute has a PDU-scale scheme called the Recycle Oil Pyrolysis and Extraction (ROPE) process, which combines solvent (hot recycle bitumen) and pyrolytic extraction. 14 refs., 19 figs.

An evaluation of the potential end uses of a Utah tar sand bitumen. [Tar sand distillate  

SciTech Connect (OSTI)

To date the commercial application of tar sand deposits in the United States has been limited to their use as paving materials for county roads, parking lots, and driveways because the material, as obtained from the quarries, does not meet federal highway specifications. The bitumen in these deposits has also been the subject of upgrading and refining studies to produce transportation fuels, but the results have not been encouraging from an economic standpoint. The conversion of tar sand bitumen to transportation fuels cannot compete with crude oil refining. The purposes of this study were two-fold. The first was to produce vacuum distillation residues and determine if their properties met ASTM asphalt specifications. The second was to determine if the distillates could serve as potential feedstocks for the production of aviation turbine fuels. The bitumen used for this study was the oil produced during an in situ steamflood project at the Northwest Asphalt Ridge (Utah) tar sand deposit. Two distillation residues were produced, one at +316/sup 0/C and one at +399/sup 0/C. However, only the lower boiling residue met ASTM specifications, in this case as an AC-30 asphalt. The original oil sample met specifications as an AC-5 asphalt. These residue samples showed some unique properties in the area of aging; however, these properties need to be investigated further to determine the implications. It was also suggested that the low aging indexes and high flow properties of the asphalts may be beneficial for pavements that require good low-temperature performance. Two distillate samples were produced, one at IBP-316/sup 0/C and one at IBP-399/sup 0/C. The chemical and physical properties of these samples were determined, and it was concluded that both samples appear to be potential feedstocks for the production of aviation turbine fuels. However, hydrogenation studies need to be conducted and the properties of the finished fuels determined to verify the prediction. 14 refs., 12 tabs.

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 (OSTI)

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. More specific and detailed information is provided in the topical reports referenced in the related publications listings.

Oil  

E-Print Network [OSTI]

Waste oils offer a tremendous recycling potential. An important, dwindling natural resource of great economic and industrial value, oil products are a cornerstone of our modern industrial society. Petroleum is processed into a wide variety of products: gasoline, fuel oil, diesel oil, synthetic rubber, solvents, pesticides, synthetic fibres, lubricating oil, drugs and many more ' (see Figure 1 1. The boilers of Amercian industries presently consume about 40 % of the used lubricating oils collected. In Ontario, the percentage varies from 20 to 30%. Road oiling is the other major use of collected waste oils. Five to seven million gallons (50-70 % of the waste oil col1ected)is spread on dusty Ontario roads each summer. The practice is both a wasteful use of a dwindling resource and an environmental hazard. The waste oil, with its load of heavy metals, particularly lead, additives including dangerous polynuclear aromatics and PCBs, is carried into the natural environment by runoff and dust to contaminate soils and water courses.2 The largest portion of used oils is never collected, but disappears into sewers, landfill sites and backyards.

Comparisons of hydrocarbon and nitrogen distributions in geologically diverse tar sand bitumen  

SciTech Connect (OSTI)

The characteristics of bitumens from different tar sand deposits are generally significantly different and affect the utilization of the resource. The chemical and physical properties of bitumen are a result of maturation reactions on the varied organic sediments. For example, saturated hydrocarbon distributions have been related to the geochemical history of organic matter. Very paraffinic or sometimes paraffinic-naphthenic distributions in organic matter are derived from a nonmarine depositional environment. More aromatic and paraffinic-naphthenic hydrocarbon distributions are derived from organic matter deposited in a marine environment. The characteristics of the bitumen also influence the potential for recovery and subsequent processing of the material. For example, saturated hydrocarbons contribute to the high pour points of recovered oils. The origin and composition of an oil influence its viscosity, API gravity, and coke formation during processing, particularly under low-temperature oxidation conditions. The objective of this work is to determine the chemical and physical properties of several samples of bitumen from geologically diverse tar sand deposits. The compound-type distributions and LTD properties of these bitumens are discussed relative to the depositional environment and processing potential of the organic matter.

An approach for simulation of paraffin deposition in pipelines as a function of flow characteristics with a reference to Teesside oil pipeline  

SciTech Connect (OSTI)

Paraffin deposition is experienced in pipelines during transportation of oil when the oil temperature is cooled below its paraffin deposition temperature. The formed paraffin crystals in the bulk flow are believed to be transported by molecular, brownian diffusion and shear dispersion. Gravity settling mechanism in previous work in the authors` laboratory has been shown to contribute to the total paraffin deposition, however, to a lesser extent than the above mentioned mechanisms. The work done here demonstrates that the paraffin deposition by molecular diffusion mechanism is a dominant one. This is in agreement with other previous studies done on the paraffin deposition. In this study, however, experimental design was made to quantify this statement. The paraffin concentration gradient (dc/dr) is the driving force of the molecular diffusion mechanism (where r is the pipeline radius). In pipelines the cooling rate is one of many factors that affect the paraffin deposition profile. Equipment was designed to simulate the flow characteristics at pipeline pressure. A three dimensional model was developed for paraffin deposition rates at various flow regimes. The developed experimental approach and the designed equipment for simulating the pipeline conditions are presented in this paper.

Red Fork sandstone of Oklahoma: depositional history and reservoir distribution  

SciTech Connect (OSTI)

The Middle Pennsylvanian Red Fork sandstone formed as a result of progradation across eastern Kansas and most of Oklahoma. The Red Fork is one of several transgressive-regressive sequences (cyclothems) developed within the Desmoinesian Cherokee Group. Sea level changes, together with varying subsidence, were dominant factors controlling the general stratigraphic (correlative) characteristics of the Red Fork interval. Progradation was episodic, with sand deposition in the more active part of the basin during lower sea level stands and valley-fill deposition in the more stable areas during sea level rises. A map of Red Fork sand trends reveals an alluvial-deltaic complex covering most of Oklahoma. The Red Fork consists primarily of alluvial-valley and plain (fluvial) bodies in the northernmost part of northeastern Oklahoma, alluvial-deltaic bodies in most of the remaining parts of the shelf area, and off-shelf submarine-fan and slope basinal-floor complexes within the deeper part of the Anadarko basin. Determination of reservoir trend and genesis requires integration of rock and log data. Logs need to be calibrated to cores in order to estimate depositional environments accurately and to make a reasonable assessment of diagenetic overprints. Much of the oil and gas has been trapped in stratigraphic traps, and a significant amount of oil is in channel sandstones with trends at high angles to the structural grain. In some areas, secondary clay, in particular chloritic clay, has resulted in microporosity, high water saturation, and correspondingly low resistivities in oil reserves.

Chemical Methods for Ugnu Viscous Oils  

SciTech Connect (OSTI)

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

Research investigations in oil shale, tar sand, coal research, advanced exploratory process technology, and advanced fuels research: Volume 2 -- Jointly sponsored research program. Final report, October 1986--September 1993  

SciTech Connect (OSTI)

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. More specific and detailed information is provided in the topical reports referenced in the related publications listings.

The potential use of tar sand bitumen as paving asphalt  

SciTech Connect (OSTI)

In this paper several research reports describing the preparation of potential paving asphalts from tar sand bitumen are reviewed and the results of the studies compared. The tar sand asphalts described in the studies were prepared from 1) hot water-recovered bitumen from deposits near San Luis Obispo, California (Edna deposits), and deposits near Vernal and Sunnyside, Utah; and 2) bitumen recovered from the Northwest Asphalt Ridge deposits near Vernal, Utah, by both in situ steamflood and in situ combustion recovery processes. Important properties of the tar sand asphalts compare favorably with those of specification petroleum asphalts. Laboratory data suggest that some tar sand asphalts may have superior aging characteristics and produce more water-resistant paving mixtures than typical petroleum asphalts.

Depositional environments and facies analysis of the Cherokee Group in west-central Kansas  

SciTech Connect (OSTI)

The Cherokee Group of early Desmoinesian Pennsylvanian age in west-central Kansas is comprised of a mixed siliciclastic and carbonate sequence. It was deposited in environments that are transitional from continental to marginal marine as the Hugoton Sea transgressed the Mississippian unconformity on to the Central Kansas uplift. Sandstones of the Cherokee Group are important oil reservoirs in west-central Kansas, but they are highly variable and difficult to predict. Core studies and subsurface analysis reveal two persistent and widespread limestone beds that form useful stratigraphic markers within the Cherokee. They provide a framework for facies analysis and regional mapping that may be useful as a predictive tool for oil exploration. Six basic lithofacies are interpreted from lithologies and sedimentary structures observed in cores obtained from four wells in eastern Ness County: (1) basal Pennsylvanian conglomerate, (2) fluvial sands, (3) fine-grained tidal flat deposits, (4) shallow-marine limestones, (5) shoreline sands and tidal channel sands, and (6) braided stream, sandy conglomerates. These facies are correlative with components of an ideal Kansas cyclothem. Two transgressive-regressive cycles are identified and maximum transgression is correlated with two widespread limestone beds. Following burial of the Mississippian karstic surface, deposition of peritidal sediments occurred on a uniform shallow shelf, punctuated by periods of subaerial exposure and weathering. Clastics derived from the eroding Central Kansas uplift were probably supplied to the coastal plain by braided streams and reworked by coastal processes.

Determining sand-body geometries for waterflood reservoirs: Examples from Oklahoma  

SciTech Connect (OSTI)

Waterflood projects require an accurate knowledge of reservoir geometry and well-to-well continuity. However, sandstones with thin, multiple-pay zones can be extremely difficult to correlate with confidence. Two case studies of Pennsylvanian sandstones in Oklahoma illustrate how a model for the depositional history of such reservoirs can be an effective tool for determining reservoir continuity. In contrast, correlation criteria such as similar wireline log signatures and relative sand-body thicknesses are not reliable in many situations. In Southwest Logan field (Beaver County), 5 to 15-ft thick reservoir sands formed as shallow marine sand ridges. Their dimensions were approximated from height-to-width ratios of modern sand ridges. Then the reservoir sands were mapped using wireline logs and core data. Individual reservoir sands were approximately 1-2 km wide and stacked en echelon vertically. Thus, a line-drive waterflood pattern oriented parallel to the axes of the ridges is recommended. Tatums field (Carter County) consists of 5 to 50-ft thick sandstones deposited in various deltaic environments. Distributary channel sands have good continuity downdip, but are narrow and lenticular across depositional strike. Crevasse splay and other bay-fill sands were deposited marginal to the channels and are extremely discontinuous. This depositional model can be used to improve flood patterns for these sands, leading to improved sweep efficiency. In both examples, for effective mapping, the depositional facies models have been used to register reservoir quality and wireline log signatures.

Utah Heavy Oil Program  

SciTech Connect (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.

DEVELOPMENT OF SHALLOW VISCOUS OIL RESERVES IN NORTH SLOPE  

SciTech Connect (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 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.

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. 1 fig., 1 tab.

Unconventional Oil and Gas Resources  

SciTech Connect (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.

Heats of dissolution of tar sand bitumen in various solvents  

SciTech Connect (OSTI)

The dissolution of tar sand bitumen from a tar sand matrix was examined using three solvents: (1) dichloromethane, a polar-polarizable solvent; (2) toluene, a nonpolar-polarizable solvent; and (3) hexane, a nonpolar-nonpolarizable solvent. The dichloromethane had the highest dissolution energy, followed by toluene, with hexane having the lowest dissolution energy. These data were combined with heat of dissolution of recovered bitumen and heat of wetting of spent sand to calculate the bonding energy between bitumen and the mineral matrix. The interfacial bonding energy between tar sand bitumen and the mineral matrix was found to be in the region of 0 to 0.09 cal/g of bitumen, which is very small. This conclusion may find application in recovery of energy or bitumen from bitumen-wet tar sand deposits. 9 refs., 2 tabs.

Solvent extraction of Southern US tar sands  

SciTech Connect (OSTI)

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.

Process for upgrading tar sand bitumen  

SciTech Connect (OSTI)

A process is described for upgrading a charge of a tar sand bitumen concentrate containing mineral matter including fine particles which comprises contacting the charge in a riser in the presence of a low boiling organic solvent diluent with finely divided attrition-resistant particles of a hot fluidizable substantially catalytically inert solid which is substantially chemically inert to a solution of mineral acid. The contact of the charge with the particles is at high temperature and short contact time to vaporize the high hydrogen containing components of the bitumen, the period of time being less than that which induces substantial thermal cracking of the charge, at the end of the time separating the vaporizing product from the fluidizable particles. The fluidizable particles now bear a deposit of both combustible solid, adherent particles of fine particles of mineral matter and metals. The particles of inert solid are passed with deposit of combustibles and fine particles of mineral matter to a regenerator to oxidize the combustible portion of the deposits, removing at least a portion of deposit of mineral matter and metals by removing the inert solid from the regenerator and contacting removed inert solid with a hot mineral acid, and recirculating fluidizable solid depleted at least in part of deposited mineral matter to contact with incoming charge of tar sand bitumen concentrate and diluent.

The five types of plays are as follows: (1) naturally fractured oil reservoirs, (2) low-permeability oil reservoirs, (3) high-permeability of oil reservoirs, (4) low-permeability gas reservoirs, and (5) tight gas sands. Several fields produce from multiple plays, which made it necessary to segregate the hydrocarbon production into several plays. The stratigraphic position of the main producing intervals is shown on a basin-wide cross section, which is color-coded by play type. This 61-well cross section has several wells from each significant Tertiary oil and gas field in the Uinta basin.

DEVELOPMENT OF SHALLOW VISCOUS OIL RESERVES IN NORTH SLOPE  

SciTech Connect (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.

Oils and source rocks from the Anadarko Basin: Final report, March 1, 1985-March 15, 1995  

SciTech Connect (OSTI)

The research project investigated various geochemical aspects of oils, suspected source rocks, and tar sands collected from the Anadarko Basin, Oklahoma. The information has been used, in general, to investigate possible sources for the oils in the basin, to study mechanisms of oil generation and migration, and characterization of depositional environments. The major thrust of the recent work involved characterization of potential source formations in the Basin in addition to the Woodford shale. The formations evaluated included the Morrow, Springer, Viola, Arbuckle, Oil Creek, and Sylvan shales. A good distribution of these samples was obtained from throughout the basin and were evaluated in terms of source potential and thermal maturity based on geochemical characteristics. The data were incorporated into a basin modelling program aimed at predicting the quantities of oil that could, potentially, have been generated from each formation. The study of crude oils was extended from our earlier work to cover a much wider area of the basin to determine the distribution of genetically-related oils, and whether or not they were derived from single or multiple sources, as well as attempting to correlate them with their suspected source formations. Recent studies in our laboratory also demonstrated the presence of high molecular weight components(C{sub 4}-C{sub 80}) in oils and waxes from drill pipes of various wells in the region. Results from such a study will have possible ramifications for enhanced oil recovery and reservoir engineering studies.

ERCB updates estimated reserves of crude bitumen and synthetic crude oil  

SciTech Connect (OSTI)

The Alberta Energy Resources Conservation Board prepares yearly updates of Alberta reserves of crude bitumen and synthetic crude oil. The latest figures are as of the end of 1985. Alberta's crude bitumen reserves are contained in designated deposits with the oil sand areas of Athabasca, Cold Lake, and Peace River. The total initial volume of crude bitumen in-place for the designated deposits at December 31, 1985 was estimated as 266.4 billion cubic meters. Within the potentially mineable areas, the initial mineable volume in-place of crude bitumen was established to be 11.9 billion cubic meters. After allowing for surface facilities (plant sites, tailings ponds, discard dumps), environmental protection corridors along major rivers, isolated mineable areas, and assuming a combined mining/extraction recovery factor of 0.78, the resulting initial established mineable reserve of crude bitumen is estimated to be 5.2 billion cubic meters. Data are presented in three tables.

Water issues associated with heavy oil production.  

SciTech Connect (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.

Production of bitumen-derived hydrocarbon liquids from Utah's tar sands: Final report  

SciTech Connect (OSTI)

In previous work done on Utah's tar sands, it had been shown that the fluidized-bed pyrolysis of the sands to produce a bitumen-derived hydrocarbon liquid was feasible. The research and development work conducted in the small-scale equipment utilized as feed a number of samples from the various tar sand deposits of Utah elsewhere. The results from these studies in yields and quality of products and the operating experience gained strongly suggested that larger scale operation was in order to advance this technology. Accordingly, funding was obtained from the State of Utah through Mineral Leasing Funds administered by the College of Mines and Earth Sciences of the University of Utah to design and build a 4-1/2 inch diameter fluidized-bed pilot plant reactor with the necessary feeding and recovery equipment. This report covers the calibration and testing studies carried out on this equipment. The tests conducted with the Circle Cliffs tar sand ore gave good results. The equipment was found to operate as expected with this lean tar sand (less than 5% bitumen saturation). The hydrocarbon liquid yield with the Circle Cliffs tar sand was found to be greater in the pilot plant than it was in the small unit at comparable conditions. Following this work, the program called for an extensive run to be carried out on tar sands obtained from a large representative tar sand deposit to produce barrel quantities of liquid product. 10 refs., 45 figs., 11 tabs.

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.

A method of separating oil or bitumen from tar or oil sand without a surfactant is described which comprises the steps of: (a) grinding the sand in the presence of a predetermined amount of a halohydrocarbon solvent to reduce lumps of the sand to a finely divided sand grains and dissolve the oil or bitumen covering the sand grains to form a solution containing a predetermined concentration of the oil or bitumen; (b) after step (a), mixing the finely divided sand grains and the oil or bitumen solution formed in step (a) with water, (c) adding additional halohydrocarbon solvent to the water-wet sand produced in step (b) in an amount sufficient to substantially reduce the strength and thickness of the membrane-like material; and (d) mixing additional water with the mixture produced in step (c) under conditions of agitation of the sand grains sufficient to remove entrapped oil or bitumen solution from the water sand, thereby obtaining free-flowing, water-wet sand particles.

Holocene stratigraphy of the Alabama inner continental shelf: Influence of shelf sand ridges on determining lithofacies architecture  

SciTech Connect (OSTI)

Surface and subsurface distribution of lithofacies from Holocene sediments of the AL inner continental shelf was determined from a series of 59 vibracores and associated surface sediment grab sediments. Five Holocene lithofacies composed of 12 discrete microfacies were delineated based on grain size, color, sedimentary structures, shell content, and fabric of samples. These lithofacies include: (1) Graded Shelly Sand Lithofacies; (2) Clean Sand Lithofacies; (3) Dirty Sand Lithofacies; (4) Biogenic Sediment Lithofacies; and (5) Muddy Sediment Lithofacies. These represent four major depositional environments: The Shelf Sand Sheet Environment (lithofacies 1 and 2); the Sand Ridge Environment (lithofacies 1, 2, and 3); the Bay/Lagoon Environment (lithofacies 3, 4 and 5); and the Muddy Shelf Environment (lithofacies 5). East of the Main Pass of Mobile Bay, the seafloor is composed of a clean Shelf Sand Sheet with oblique shelf sand ridges; Clean Sand and Graded Shelly Sand are the dominant surface sediment types. Coarse shell beds that grade up to quartz sand units (total thickness 0.1 to 3+m) interpreted as tempestites comprise most of the upper portion of the ridges. West of the Pass, the muddier lithofacies (3 and 5) dominate surface samples. Microfacies at depth represent the early Holocene transgressive systems tract; these include the Muddy Shelf Depositional Environment and the filled estuaries and bays of the flooded Pleistocene fluvial valleys represented by the Bay/Lagoon Depositional Environment. The AL inner shelf provides an excellent model of the variability of sedimentation mode in time and space during deposition of a transgressive systems tract. Development of the palimpsest sand sheet/ridge complex progressed on the eastern shelf due to shut off of sediment influx, westward longshore currents, and episodic incidence of major hurricanes. On the western shelf a patchy distribution of muddier sediments developed from input of floodwaters from Mobile Bay.

SciTech Connect (OSTI)

Pilot-plant-scale demonstration of an upgrading/refining scheme to convert bitumen or heavy crude oil into high yields of specification-quality aviation turbine fuel was performed. An atmospheric residue from San Ardo (California) crude was converted under hydrovisbreaking conditions to synthetic crude for further refining. Naphtha cuts from the straight run and synthetic crude were combined, catalytically hydrotreated, then hydrocracked. Products from these operations were combined to produce two prototype specification fuels (JP-4 and JP-8) as well as two heavier, variable-quality fuels. An engineering design (Volume II) was developed for a 50,000 BPSD grass-roots refinery, from the pilot-plant operations. Capital investment and operating costs were estimated, and fuel manufacturing costs projected. Conclusions and recommendations for further work are included.

Polymer treatments for D Sand water injection wells: Sooner D Sand Unit Weld County, Colorado. Final report, April 1997  

SciTech Connect (OSTI)

Polymer-gel treatments in injection wells were evaluated for improving sweep efficiency in the D Sandstone reservoir at the Sooner Unit, Weld County, Colorado. Polymer treatments of injection wells at the Sooner Unit were expected to improve ultimate recovery by 1.0 percent of original-oil-in-place of 70,000 bbl of oil. The Sooner D Sand Unit was a demonstration project under the US Department of Energy Class I Oil Program from which extensive reservoir data and characterization were obtained. Thus, successful application of polymer-gel treatments at the Sooner Unit would be a good case-history example for other operators of waterfloods in Cretaceous sandstone reservoirs in the Denver Basin.

TULSA UNIVERSITY PARAFFIN DEPOSITION PROJECTS  

SciTech Connect (OSTI)

As oil and gas production moves to deeper and colder water, subsea multiphase production systems become critical for economic feasibility. It will also become increasingly imperative to adequately identify the conditions for paraffin precipitation and predict paraffin deposition rates to optimize the design and operation of these multiphase production systems. Although several oil companies have paraffin deposition predictive capabilities for single-phase oil flow, these predictive capabilities are not suitable for the multiphase flow conditions encountered in most flowlines and wellbores. For deepwater applications in the Gulf of Mexico, it is likely that multiphase production streams consisting of crude oil, produced water and gas will be transported in a single multiphase pipeline to minimize capital cost and complexity at the mudline. Existing single-phase (crude oil) paraffin deposition predictive tools are clearly inadequate to accurately design these pipelines because they do not account for the second and third phases, namely, produced water and gas. The objective of this program is to utilize the current test facilities at The University of Tulsa, as well as member company expertise, to accomplish the following: enhance our understanding of paraffin deposition in single and two-phase (gas-oil) flows; conduct focused experiments to better understand various aspects of deposition physics; and, utilize knowledge gained from experimental modeling studies to enhance the computer programs developed in the previous JIP for predicting paraffin deposition in single and two-phase flow environments. These refined computer models will then be tested against field data from member company pipelines. The following deliverables are scheduled during the first three projects of the program: (1) Single-Phase Studies, with three different black oils, which will yield an enhanced computer code for predicting paraffin deposition in deepwater and surface pipelines. (2) Two-Phase Studies, with a focus on heat transfer and paraffin deposition at various pipe inclinations, which will be used to enhance the paraffin deposition code for gas-liquid flow in pipes. (3) Deposition Physics and Water Impact Studies, which will address the aging process, improve our ability to characterize paraffin deposits and enhance our understanding of the role water plays in paraffin deposition in deepwater pipelines. As in the previous two studies, knowledge gained in this suite of studies will be integrated into a state-of-the-art three-phase paraffin deposition computer program.

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

SciTech Connect (OSTI)

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.

Process sedimentology and reservoir quality of deep-marine bottom-current reworked sands (sandy contourites): An example from the Gulf of Mexico  

SciTech Connect (OSTI)

Deep-marine bottom-current reworked sands (sandy contourites) have been recognized in hydrocarbon-bearing sands of the Gulf of Mexico. A distinctive attribute of these sands is their traction bed forms, which occur in discrete units. Common sedimentary features of traction currents include cross-bedding, current ripples, horizontal lamination, sharp upper contacts, and inverse size grading. These sands also exhibit internal erosional surfaces and mud offshoots, indicating oscillating current energy conditions. THe Pliocene-Pleistocene sequence cored in the Ewing Bank Block 826 field in the Gulf of Mexico provides an example of sand distribution and reservoir quality of deep-marine bottom-current reworked sands. Presumably, the Loop Current, a strong wind-driven surface current in the Gulf of Mexico, impinged on the sea bottom, as it does today, and resulted in bottom-current reworked sands. A depositional model based on the integration of well (core and log) and three-dimensional seismic data suggests that the reworked sediment package may be thick and continuous, but individual sand layers within the package may be thin and discontinuous. This unconventional model, which depicts the distribution of bottom-current reworked sands in interchannel slope areas as a distinctly different facies from channel-levee facies, has the potential for general application to other slope plays outside the study area. In the Ewing Bank Block 826 field, the type I (L-1) reservoir with 80% sand exhibits higher permeability values (100-1800 md) than the type 2 (N-1) reservoir with 26% sand (50-800 md). The increased permeability in the type I sand has been attributed to high sand content, vigorous reworking, and microfractures. The clean, porous, and well-sorted type 1 sands with good communication between sand layers have produced at higher rates and recovery efficiencies than the type 2 sands with numerous interbedded mud layers. 50 refs., 22 figs., 1 tab.

Office of Naval Petroleum and Oil Shale Reserves  

E-Print Network [OSTI]

Worldwide supplies of conventional oil will soon reach a peak production rate and begin an irreversible long-term decline. Options to augment liquid fuel supplies in the United States have once again begun to focus on oil shale as long-term source of reliable, affordable, and secure oil. The United States government has long recognized the strategic potential of the nation’s vast oil shale resources to support national security. President Taft in 1912 established an Office of Naval Petroleum and Oil Shale Reserves and charged that office with ensuring oil for naval military operations. This office continues to oversee the United States strategic interest in oil shale. America’s 2 trillion barrel oil shale resource is recognized as having the same production potential as Canada’s tar sands. Tar sand production, initiated in the 1960s, has increased steadily to more than 1 million per barrels/day and is moving toward a near-term goal of 2.5 million barrels per day by 2017. This amount of oil is equivalent to the volume of oil currently imported by the United States from Middle East countries. Tar sands production has enabled Canada to add 174 billion barrels to its recoverable oil reserves, making Canada’s proved reserves second only to those of Saudi Arabia.

Depositional framework and reservoir distribution of Red Fork sandstone in Oklahoma  

SciTech Connect (OSTI)

The Middle Pennsylvanian Red Fork sandstone formed as a result of southward progradation across most of Oklahoma. The Red Fork is one of several cyclothemic (transgressive-regressive) sequences developed within the Desmoinesian Cherokee Group. Sea level changes and stability of the depositional area were dominant factors in determining the general stratigraphic characteristics of the Red Fork interval. Progradation was episodic, with sand deposition in the distal, more subsident part of the basin during lower sea level stands, and valley-fill deposition in the more stable areas during sea level rises. Red Fork sandstone trends depict an alluvial-deltaic complex covering most of Oklahoma. The Red Fork consists primarily of alluvial-valley and plain (fluvial) bodies in the northern part of northeastern Oklahoma, alluvial-deltaic bodies in most of the remaining parts of the shelf area, and off-shelf submarine-fan and slope/basin-floor complexes within the deeper part of the Anadarko basin. Determination of reservoir trend and genesis requires integration of rock data and log data, with logs calibrated to cores for estimating depositional environments and assessing diagenetic overprints. Much of the oil and gas has been trapped in stratigraphic traps, some of which represent channelized sandstones with trends at high angles to the structural grain. Secondary chlorite, in particular, is associated locally with development of productive reservoirs showing microporosity, high water saturation, and correspondingly low resistivities.

Process for upgrading tar sand bitumen  

SciTech Connect (OSTI)

A process is described for upgrading a charge of a tar sand bitumen concentrate containing metal impurities, colloidal calcium-containing clay and water. It consists of contacting the charge in a riser contacting zone in the presence of a low boiling organic solvent with hot fluidizable attrition-resistant substantially catalytically-inert microspheres, which are 20 to 150 microns in diameter and are composed of previously calcined kaolin clay. The contact takes place at high temperature and short contact time, which permits vaporization of the high hydrogen containing components of the bitumen. The period of time is less than that which induces substantial thermal cracking of the charge. At the end of the time the vaporized produce is separated from the microspheres of calcined kaolin clay, the microspheres of calcined kaolin clay now bearing a deposit of combustible solid, metal impurities and adherent particles of colloidal calcium-containing clay originally contained in the bitumen concentrate, immediately reducing the temperature of the vaporized product to minimize thermal cracking and recovering the product for further refining to produce one or more premium products.

High-Temperature Nuclear Reactors for In-Situ Recovery of Oil from Oil Shale  

SciTech Connect (OSTI)

The world is exhausting its supply of crude oil for the production of liquid fuels (gasoline, jet fuel, and diesel). However, the United States has sufficient oil shale deposits to meet our current oil demands for {approx}100 years. Shell Oil Corporation is developing a new potentially cost-effective in-situ process for oil recovery that involves drilling wells into oil shale, using electric heaters to raise the bulk temperature of the oil shale deposit to {approx}370 deg C to initiate chemical reactions that produce light crude oil, and then pumping the oil to the surface. The primary production cost is the cost of high-temperature electrical heating. Because of the low thermal conductivity of oil shale, high-temperature heat is required at the heater wells to obtain the required medium temperatures in the bulk oil shale within an economically practical two to three years. It is proposed to use high-temperature nuclear reactors to provide high-temperature heat to replace the electricity and avoid the factor-of-2 loss in converting high-temperature heat to electricity that is then used to heat oil shale. Nuclear heat is potentially viable because many oil shale deposits are thick (200 to 700 m) and can yield up to 2.5 million barrels of oil per acre, or about 125 million dollars/acre of oil at $50/barrel. The concentrated characteristics of oil-shale deposits make it practical to transfer high-temperature heat over limited distances from a reactor to the oil shale deposits. (author)

DEVELOPMENT OF SHALLOW VISCOUS OIL RESERVES IN NORTH SLOPE  

SciTech Connect (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. Coreflood, quarter 5-spot study, compositional simulation, wettability, relative permeability study and streamline-based simulation were conducted in this project. 1D compositional simulation results agree reasonably well with those of the slim tube experiments. Injection of CO{sub 2}-NGL is preferable over that of PBG-NGL. MME is sensitive to pressure (in the range of 1300-1800 psi) for the injection of PBG-NGL, but not for CO{sub 2}-NGL. Three hydrocarbon phases form in this pressure range. As the mean thickness of the adsorbed organic layer on minerals increases, the oil-water contact angle increases. The adsorbed organic films left behind after extraction of oil by common aromatic solvents used in core studies, such as toluene and decalin, are thinner than those left behind by non-aromatic solvents, such as cyclohexane. The force of adhesion for minerals aged with just the asphaltene fraction is similar to that of the whole oil implying that asphaltenes are responsible for the mixed-wettability in this reservoir. A new relative permeability model for a four-phase, mixed-wet system has been proposed. A streamline module is developed which can be incorporated in an existing finite-difference based compositional simulator to model water flood, gas flood and WAG flood. Horizontal wells increase well deliverability over vertical wells, but sweep efficiency can decrease. The well performance depends on the well length, position, heterogeneity, and viscosity ratio. The productivity increase due to electromagnetic heating is a function of power intensity, flow rate, and frequency etc. The productivity of a well can be doubled by electromagnetic heating. A high-pressure quarter 5-spot model has been constructed to evaluate the sweep efficiency of miscible WAG floods. WAG displacement reduces bypassing compared to gas floods and improves oil recovery in cores. As the WAG ratio decreased and slug size increased, oil recovery increased. Oil was recovered faster with increased slug size and decreased WAG ratio in the simulations for field cases studied.

African oil plays  

SciTech Connect (OSTI)

The vast continent of Africa hosts over eight sedimentary basins, covering approximately half its total area. Of these basins, only 82% have entered a mature exploration phase, 9% have had little or no exploration at all. Since oil was first discovered in Africa during the mid-1950s, old play concepts continue to bear fruit, for example in Egypt and Nigeria, while new play concepts promise to become more important, such as in Algeria, Angola, Chad, Egypt, Gabon, and Sudan. The most exciting developments of recent years in African oil exploration are: (1) the Gamba/Dentale play, onshore Gabon; (2) the Pinda play, offshore Angola; (3) the Lucula/Toca play, offshore Cabinda; (4) the Metlaoui play, offshore Libya/Tunisia; (5) the mid-Cretaceous sand play, Chad/Sudan; and (6) the TAG-I/F6 play, onshore Algeria. Examples of these plays are illustrated along with some of the more traditional oil plays. Where are the future oil plays likely to develop No doubt, the Saharan basins of Algeria and Libya will feature strongly, also the presalt of Equatorial West Africa, the Central African Rift System and, more speculatively, offshore Ethiopia and Namibia, and onshore Madagascar, Mozambique, and Tanzania.

Hydraulic conductivity of shaly sands  

SciTech Connect (OSTI)

The effects of clays on the hydraulic conductivity of a sandstone are analyzed by considering a simple clay coating structure for the sand grains. In the model, silicate insulating nuclei are uniformly surrounded by charged clay particles. The total charge on the clays is compensated by a counterion density Q{sub v}. Assuming a capillary flow regime inside this granular model a Kozeny-Carman type equation has been derived, expressing its intrinsic permeability k in terms of a porosity-tortuosity factor {phi}{sup (m{minus}0.5)} and of the parameter Q{sub v}. The power-law derived expression shows that k decreases with the amount of clay, not only because a high Q{sub v} implies a narrowing of the pore channels, but also because it modifies the hydraulic tortuosity of the medium. This new equation has been statistically tested with extensive petrophysical laboratory data for different types of shaly sandstones.

Shock response of dry sand.  

SciTech Connect (OSTI)

The dynamic compaction of sand was investigated experimentally and computationally to stresses of 1.8 GPa. Experiments have been performed in the powder's partial compaction regime at impact velocities of approximately 0.25, 0.5, and 0.75 km/s. The experiments utilized multiple velocity interferometry probes on the rear surface of a stepped target for an accurate measurement of shock velocity, and an impedance matching technique was used to deduce the shock Hugoniot state. Wave profiles were further examined for estimates of reshock states. Experimental results were used to fit parameters to the P-Lambda model for porous materials. For simple 1-D simulations, the P-Lambda model seems to capture some of the physics behind the compaction process very well, typically predicting the Hugoniot state to within 3%.

CAVITY LIKE COMPLETIONS IN WEAK SANDS PREFERRED UPSTREAM MANAGEMENT PRACTICES  

SciTech Connect (OSTI)

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.

Definition of heavy oil and natural bitumen  

SciTech Connect (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.

Shale oil recovery process  

DOE Patents [OSTI]

A process of producing within a subterranean oil shale deposit a retort chamber containing permeable fragmented material wherein a series of explosive charges are emplaced in the deposit in a particular configuration comprising an initiating round which functions to produce an upward flexure of the overburden and to initiate fragmentation of the oil shale within the area of the retort chamber to be formed, the initiating round being followed in a predetermined time sequence by retreating lines of emplaced charges developing further fragmentation within the retort zone and continued lateral upward flexure of the overburden. The initiating round is characterized by a plurality of 5-spot patterns and the retreating lines of charges are positioned and fired along zigzag lines generally forming retreating rows of W's. Particular time delays in the firing of successive charges are disclosed.

Characterization of various bitumen samples from tar sands  

SciTech Connect (OSTI)

The authors have investigated twenty three bitumen samples obtained using different separation methods such as: ultracentrifugation, Dean-Stark extraction, solvent extraction employing vigorous agitation, hot water separation and the Solvent Extraction Spherical Agglomeration technique. These samples were extracted from oil sand feedstocks of different grades, Suncor sludge pond tailings and mineral agglomerates obtained form the Solvent Extraction Spherical Agglomeration process. All of the bitumen samples were examined on a comparative basis using various analytical techniques. These included: fractionation into asphaltenes and maltenes: elemental analyses; molecular weight determination using vapour pressure osmometry and gel permeation chromatography, infrared, proton and /sup 13/C nuclear magnetic resonance spectroscopy. Proton /sup 13/C n.m.r. spectroscopic data were used to determine the distribution of various types of hydrogens and carbons in the samples. These data were also used to derive various molecular parameters in order to investigate average molecular structures of different bitumen samples and some of their asphaltene fractions.

Potential turbine fuels from western Kentucky tar sand bitumen  

SciTech Connect (OSTI)

The declining quality of petroleum is a particular problem for aviation turbine fuels. Since these fuels are required to meet stringent corrosion, thermal stability and purity specification, very little in the way of contaminants or heteroatoms can be tolerated. However, heavier and more sour crude supplied result in lower straight-run turbine fuel yields, higher sulfur contents, and higher aromatic contents. While all turbine fuels were originally prepared from high quality stocks by distillation, many commercial and military fuels now require hydrotreatment to meet specifications. The work described in this program extrapolates these present trends to very heavy feedstocks. Tar sands bitumen and heavy crude oils are low API gravity, high viscosity hydrocarbonaceous materials commonly exhibiting high levels of heteroatomic species, high metals content and high levels of asphaltenes, plus water and solids not readily separated by conventional technology without dilution. Tar sands bitumen is highly cyclic with many polycyclic rings and naphthenic constituents. Sulfur is primarily in thiophenic structures, with nitrogen included in the ring structure. Asphaltenes are in high proportion, with a large amount of sulfur, nitrogen and metallic inclusions. Each of these characteristics represent specific concerns to refiners.

Characterization of various bitumen samples from tar sands  

SciTech Connect (OSTI)

Bitumen is a complex mixture of a large of number of organic molecules. The composition of bitumen and the nature of their various individual components has been the subject of considerable research during the past two decades. Various modes of extraction of bitumen from oil sands such as heat, extreme mechanical force, chemical agents and solvents could significantly affect some properties of bitumen. Variations in the composition of the oil sands feed stock could also affect the properties of the extracted bitumen. However, the most commonly used analytical techniques such as elemental analyses, density and viscosity cannot detect small compositional differences in the various samples of bitumen. With developments in instrumentation and techniques the structural characterization of complex petroleum fractions employing high resolution proton and 13/sub C/ nuclear magnetic resonance (NMR) spectroscopy is becoming more popular. The parameters describe structural features, such as the fraction of carbon that is aromatic, the number and length of alkyl substituents in an average molecule, the percentage of aromatic carbons that are substituted and the number of aromatic rings per molecule. Given sufficient data these parameters can provide useful characterization of a hydrocarbon mixture. In the authors' laboratories, the authors have collected a number of bitumen samples obtained from different feedstocks employing a variety of extraction techniques. It was of interest to investigate any differences between these samples from different sources. This paper reports a detailed investigation of average structural parameters by the combined use of elemental analyses, molecular weight determinations and proton and 13/sub C/NMR spectroscopy. A total of twenty three butimen samples have been studied.

SOLVING THE SHUGART QUEEN SAND PENASCO UNIT DECLINING PRODUCTION PROBLEM  

SciTech Connect (OSTI)

The Penasco Shugart Queen Sand Unit located in sections 8, 9, 16 & 17, T18S, 31E Eddy County New Mexico is operated by MNA Enterprises Ltd. Co. Hobbs, NM. The first well in the Unit was drilled in 1939 and since that time the Unit produced 535,000 bbl of oil on primary recovery and 375,000 bbl of oil during secondary recovery operations that commenced in 1973. The Unit secondary to primary ratio is 0.7, but other Queen waterfloods in the area had considerably larger S/P ratios. On June 25 1999 MNA was awarded a grant under the Department of Energy's ''Technology Development with Independents'' program. The grant was used to fund a reservoir study to determine if additional waterflood reserves could be developed. A total of 14 well bores that penetrate the Queen at 3150 ft are within the Unit boundaries. Eleven of these wells produced oil during the past 60 years. Production records were pieced together from various sources including the very early state production records. One very early well had a resistivity log, but nine of the wells had no logs, and four wells had gamma ray-neutron count-rate perforating logs. Fortunately, recent offset deep drilling in the area provided a source of modern logs through the Queen. The logs from these wells were used to analyze the four old gamma ray-neutron logs within the Unit. Additionally the offset well log database was sufficient to construct maps through the unit based on geostatistical interpolation methods. The maps were used to define the input parameters required to simulate the primary and secondary producing history. The history-matched simulator was then used to evaluate four production scenarios. The best scenario produces 51,000 bbl of additional oil over a 10-year period. If the injection rate is held to 300 BWPD the oil rate declines to a constant 15 BOPD after the first year. The projections are reasonable when viewed in the context of the historical performance ({approx}30 BOPD with a {approx}600 BWPD injection rate during 1980-1990). If an additional source of water is developed, increasing the injection rate to 600 BWPD will double the oil-producing rate. During the log evaluation work the presence of a possibly productive Penrose reservoir about 200 ft below the Queen was investigated. The Penrose zone exists throughout the Unit, but appears to be less permeable than the Queen. The maps suggest that either well 16D or 16C are suitable candidates for testing the Penrose zone.

Conductivity heating a subterranean oil shale to create permeability and subsequently produce oil  

SciTech Connect (OSTI)

This patent describes an improvement in a process in which oil is produced from a subterranean oil shale deposit by extending at least one each of heat-injecting and fluid-producing wells into the deposit, establishing a heat-conductive fluid-impermeable barrier between the interior of each heat-injecting well and the adjacent deposit, and then heating the interior of each heat-injecting well at a temperature sufficient to conductively heat oil shale kerogen and cause pyrolysis products to form fractures within the oil shale deposit through which the pyrolysis products are displaced into at least one production well. The improvement is for enhancing the uniformity of the heat fronts moving through the oil shale deposit. Also described is a process for exploiting a target oil shale interval, by progressively expanding a heated treatment zone band from about a geometric center of the target oil shale interval outward, such that the formation or extension of vertical fractures from the heated treatment zone band to the periphery of the target oil shale interval is minimized.

Western oil shale conversion using the ROPE copyright process  

SciTech Connect (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.

Catalyst poisoning during tar-sands bitumen upgrading  

SciTech Connect (OSTI)

A number of hydrotreating catalysts are used in commercial heavy oil upgrading facilities. One of these, a CoO/MoO{sub 3}/Al{sub 2}O{sub 3} catalyst has been evaluated in a pilot plant CSTR for Tar-Sands Bitumen upgrading. Following its use in a test of 200 hours duration, the catalyst was removed, de-oiled, regenerated by air-calcination to remove the coke, and then re-tested. Samples of the coked, fresh and regenerated catalyst were each examined using surface analytical techniques. ESCA and SIMS analysis of the coked and regenerated catalyst samples show, as expected, significant contamination of the catalyst with Ni and V. In addition, the SIMS analysis clearly reveals that the edges of the catalyst pellets are rich in Ca, Mg and Fe while the Ni, V and coke are evenly distributed. Regeneration of the catalyst by calcination removes the carbonaceous material but appears not to change the distribution of the metal contaminants. Retesting of the regenerated catalyst shows a performance similar to that of the fresh catalyst. These data serve to support the view that catalyst deactivation during early use is not due to the skin of Ca and Mg on the pellets but rather via the poisoning of active sites by carbonaceous species.

Reservoir description of a sand-rich submarine fan complex for a steamflood project: upper Miocene Potter sandstone, North Midway Sunset field, California  

SciTech Connect (OSTI)

Nearly 650 m of cores from the upper Miocene Potter sandstone in Mobil's Alberta/Shale property, North Midway Sunset field, California, were examined to determine depositional facies, sand-body geometry, and reservoir quality for a proposed steamflood project. The Potter represents a sand-rich submarine fan complex with braided-channel, meandering-channel, levee, and crevasse-splay facies. The braided-channel facies (gravel and coarse sand) is thick (up to 100 m), sheetlike (> 500 m wide), and highly permeable (10,000 + md). The meandering-channel facies (coarse to medium sand) is up to 20 m thick, over 400 m long, lenticular in geometry, and exhibits an upward decrease in permeability (e.g., 9000 to 500 md) related to grain size that fines upward. The levee facies (in bioturbated sand) is up to 21 m thick, shows variable geometry, and is generally low in permeability (100-1500 md). The crevasse splay (medium sand) is up to 12 m thick, sheetlike (> 300 m wide), and shows moderately high permeability (2000-8000 md). The braided-channel facies was a product of density-modified grain flows, and the remaining three facies were deposited by turbidity currents. Steam flooding of the Potter reservoir should perform extremely well because the entire reservoir is composed of relatively clean sand and the reservoir lacks both horizontal and vertical permeability barriers.

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

SciTech Connect (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.

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

SciTech Connect (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.

Presented herein are results of four research areas of interest in oil shale process development: Recent Progress in Solid-Recycle Retorting and Related Laboratory and Modeling Studies; Water Generation During Pyrolysis of Oil Shale; Improved Analytical Methods and Measurements of Rapid Pyrolysis Kinetics for Western and Eastern Oil Shale; and Rate of Cracking or Degradation of Oil Vapor In Contact with Oxidized Shale. We describe operating results of a 1 tonne-per-day, continuous-loop, solid-recycle, retort processing both Western And Eastern oil shale. Sulfur chemistry, solid mixing limits, shale cooling tests and catalyst addition are all discussed. Using a triple-quadrupole mass spectrometer, we measure individual species evolution with greater sensitivity and selectivity. Herein we discuss our measurements of water evolution during ramped heating of Western and Eastern oil shale. Using improved analytical techniques, we determine isothermal pyrolysis kinetics for Western and Eastern oil shale, during rapid heating, which are faster than previously thought. Finally, we discuss the rate of cracking of oil vapor in contact with oxidized shale, qualitatively using a sand fluidized bed and quantitatively using a vapor cracking apparatus. 3 refs., 4 figs., 1 tab.

Solvent extraction of southern US tar sands  

SciTech Connect (OSTI)

The socioeconomic aspects of the tar sands recovery were investigated by Diversified Petroleum Recovery, Inc. Mineral Resources Institute at the University of Alabama conducted characterization and beneficiation studies on Alabama tar sands. Two sources in the state were identified, namely, Black Wax Hill and Spring Creek. Samples were obtained, beneficiated, then shared with the University of Arkansas. The University of Arkansas conducted research in three areas, namely, solvation and characterization of the tar sands phase equilibria as well as the design and operation of a bench-scale batch model. In the solvation studies, the results indicate that grinding the tar sands too fine results in downstream processing problems. Also, preliminary indications are that the beneficiation step may not be necessary in the solvation of the bitumen. The phase equilibria of the heptane/brine/isopropyl alcohol/XTOL{trademark} system is very complex. The salt concentration of the brine is significant in the partitioning of the isopropanol and heptane. Equilibrium data for some of the various combinations of chemical constituents have been obtained. Also included are appendices: statistical data on highways; petrography; Dean-Starke technique; FTIR and NMR spectra; FORTRAN computer program for GC; simulation of flash behavior for IPA/brine/fatty acid/N-C{sub 7} mixture; and previous progress reports. 32 figs., 28 tabs.

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.

Heavy oil production from Alaska  

SciTech Connect (OSTI)

North Slope of Alaska has an estimated 40 billion barrels of heavy oil and bitumen in the shallow formations of West Sak and Ugnu. Recovering this resource economically is a technical challenge for two reasons: (1) the geophysical environment is unique, and (2) the expected recovery is a low percentage of the oil in place. The optimum advanced recovery process is still undetermined. Thermal methods would be applicable if the risks of thawing the permafrost can be minimized and the enormous heat losses reduced. Use of enriched natural gas is a probable recovery process for West Sak. Nearby Prudhoe Bay field is using its huge natural gas resources for pressure maintenance and enriched gas improved oil recovery (IOR). Use of carbon dioxide is unlikely because of dynamic miscibility problems. Major concerns for any IOR include close well spacing and its impact on the environment, asphaltene precipitation, sand production, and fines migration, in addition to other more common production problems. Studies have indicated that recovering West Sak and Lower Ugnu heavy oil is technically feasible, but its development has not been economically viable so far. Remoteness from markets and harsh Arctic climate increase production costs relative to California heavy oil or Central/South American heavy crude delivered to the U.S. Gulf Coast. A positive change in any of the key economic factors could provide the impetus for future development. Cooperation between the federal government, state of Alaska, and industry on taxation, leasing, and permitting, and an aggressive support for development of technology to improve economics is needed for these heavy oil resources to be developed.

The effect of low-temperature oxidation on the fuel and produced oil during in situ combustion  

SciTech Connect (OSTI)

Combustion tube experiments using 10.2{degrees} API crude oil were performed, in which a different sample matrix was used in each run. Three matrix types were tested: sand, sand and clay, and sand and sand fines. As a result of the low fuel concentration, low-temperature oxidation (LTO) was observed in the run where the matrix consisted of sand only. High-temperature oxidation (HTO) was observed in runs where either clay or sand fines were part of the matrix. Ignition was not obtained in the LTO run, which had a reaction front temperature of only 350{degrees}C (662{degrees}F), compared to a combustion front temperature of 500{degrees}C (932{degrees}F) for the HTO runs. From elemental analysis, the fuel during the LTO run was determined to be an oxygenated hydrocarbon with an atomic oxygen-carbon ratio of 0.3.

Stratigraphy and depositional environments of Fox Hills Formation in Williston basin  

SciTech Connect (OSTI)

The Fox Hills Formation (Maestrichtian), representing part of a regressive wedge deposited during the withdrawal of the sea from the Western Interior at the close of the Cretaceous, consists of marginal marine strata transitional between the offshore deposits of the underlying Pierre Shale and the terrestrial deltaic and coastal deposits of the overlying Hell Creek Formation. An investigation of outcrops of the Fox Hills Formation along the western and southern flanks of the Williston basin and study of over 300 oil and gas well logs from the central part of the basin indicate that the formation can be divided both stratigraphically and areally. Stratigraphically, the Fox Hills can be divided into lower and upper sequences; the lower includes the Trail City and Timber Lake Members, and the upper sequence includes the Colgate Member in the west and the Iron Lightning and Linton Members in the east. Areally, the formation can be divided into a northeastern and western part, where the strata are 30-45 m thick and are dominated by the lower sequence, and into a southeastern area where both the lower and upper sequences are well developed in a section 80-130 m thick. Typically, the lower Fox Hills consists of upward-coarsening shoreface or delta-front sequences containing hummocky bedding and a limited suite of trace fossils, most notably Ophiomorpha. In the southeast, however, these strata are dominated by bar complexes, oriented northeast-southwest, composed of cross-bedded medium to very fine-grained sand with abundant trace and body fossils. The upper Fox Hills represents a variety of shoreface, deltaic, and channel environments. The strata of the Fox Hills Formation exhibit facies similar to those reported for Upper Cretaceous gas reservoirs in the northern Great Plains.

Three dimensional fabric evolution of sheared sand  

SciTech Connect (OSTI)

Granular particles undergo translation and rolling when they are sheared. This paper presents a three-dimensional (3D) experimental assessment of fabric evolution of sheared sand at the particle level. F-75 Ottawa sand specimen was tested under an axisymmetric triaxial loading condition. It measured 9.5 mm in diameter and 20 mm in height. The quantitative evaluation was conducted by analyzing 3D high-resolution x-ray synchrotron micro-tomography images of the specimen at eight axial strain levels. The analyses included visualization of particle translation and rotation, and quantification of fabric orientation as shearing continued. Representative individual particles were successfully tracked and visualized to assess the mode of interaction between them. This paper discusses fabric evolution and compares the evolution of particles within and outside the shear band as shearing continues. Changes in particle orientation distributions are presented using fabric histograms and fabric tensor.

Bitumen and heavy-oil resources of the United States  

SciTech Connect (OSTI)

Bitumen and heavy-oil deposits represent a significant hydrocarbon resource in the US. Bitumen deposits (10/sup 0/ API) are located in sandstone reservoirs at or near the surface along the margins of sedimentary basins. Heavy oils (10/sup 0/-20/sup 0/ API) are found predominantly in geologically young (Tertiary age and younger) shallow sandstone reservoirs and along the margins of sedimentary basins. Bitumen and heavy oil have high viscosities (10,000 cp for bitumen, 100-10,000 cp for heavy oil) and cannot be recovered by conventional recovery methods. Bitumen deposits have been evaluated in 17 states. The total bitumen resource for the conterminous US is estimated to be 57 billion bbl. Utah contains the largest resource, estimated to be 29 billion bbl, followed by California with 9 billion bbl, Alabama with 6 billion, Texas with 5 billion, and Kentucky with 3 billion. Heavy-oil deposits have been evaluated in 16 states, but most heavy oil is in California, Texas, and Arkansas. Total heavy oil in place for the conterminous US is estimated to be approximately 45 billion bbl; greater than 80% of this amount is in California. The giant Kuparuk deposit on the North Slope of Alaska contains a heavy oil-bitumen resource estimated as high as 40 billion bbl.

A full field model study of the East Velma West Block Sims Sand Unit reservoir  

SciTech Connect (OSTI)

A full-field numerical model of the East Velma West Block Sims Sand Unit (EVWBSSU) reservoir was developed. From the history-matched model, field performance predictions were made for continued waterflood and various operating scenarios under the present CO/sub 2/ injection scheme. Results include the effect of CO/sub 2/ pipeline supply rate, allocation of CO/sub 2/ and water to injection wells, and uncertain parameters on reservoir performance. From these projections it was concluded that the amount of injected CO/sub 2/ required to produce an incremental barrel of oil over waterflood was not strongly dependent on CO/sub 2/ pipeline supply rate or allocation of injected fluids to injection wells. This conclusion seems reasonable mechanistically because the miscible displacement was dominated by gravity, the areal variation in predicted updip oil saturation was not great, and the continuous injection coupled with high permeability updip caused uniform distribution of CO/sub 2/.

Bitumen and heavy oil upgrading in Canada  

SciTech Connect (OSTI)

A review is presented of the heavy oil upgrading industry in Canada. Up to now it has been based on the processing of bitumen extracted from oil sands mining operations at two sites, to produce a residue-free, low sulfur, synthetic crude. Carbon rejection has been the prime process technology with delayed coking being used by Suncor and FLUID COKING at Syncrude. Alternative processes for recovering greater amounts of synthetic crude are examined. These include a variety of hydrogen addition processes and combinations which produce pipelineable materials requiring further processing in downstream refineries with expanded capabilities. The Newgrade Energy Inc. upgrader, now under construction in Regina, will use fixed-bed, catalytic, atmospheric-residue, hydrogen processing. Two additional products, also based on hydrogenation, will use ebullated bed catalyst systems: the expansion of Syncrude, now underway, is using the LC Fining Process whereas the announced Husky Bi-Provincial upgrader is based on H-Oil.

Tidal inlet processes and deposits along a low energy coastline: easter Barataria Bight, Louisiana  

SciTech Connect (OSTI)

Historical, seismic and vibracore data were used to determine the geologic framework of sand deposits along the predominantly muddy coastline of eastern Barataria Bight, Louisiana. Three inlet types with distinct sand body geometries and morphologies were identified and are found 1) at flanking barrier island systems spread laterally across the front of interdistributary bays; 2) in old distributary channels; 3) at overwash breaches; or 4) combination of these. Barataria Bight, a sheltered barrier island shoreline embayment with limited sand supply, minimal tidal range (36 cm) and low wave energies (30 cm) can be used to show examples of each inlet type. Barataria Pass and Quatre Bayou Pass are inlets located in old distributary channels. However, Barataria Pass has also been affected by construction between barrier islands. Pass Ronquille is located where the coastline has transgressed a low area in the delta plain. This breach is situated in a hydraulically efficient avenue between the Gulf and Bay Long behind it. Pass Abel is a combination of a low-profile barrier breach and the reoccupation of an old distributary channel. Shelf and shoreline sands are reworked from abandoned deltaic distributaries and headlands. Inner shelf sands are concentrated in thick (10 m) shore-normal relict distributary channels with fine grained cross-bedded and ripple laminated sand overlain by burrowed shelf muds. Shoreface sand deposits occur as 2-3 m thick, fine-grained, coarsening upward and burrowed ebb-tidal delta sequences and shore-parallel relict tidal inlet channels filled through lateral accretion.

Characterization of Nickel and Vanadium compounds in tar sand bitumen by petroporphyrin quantitation and size exclusion chromatography coupled with element specific detection  

SciTech Connect (OSTI)

Tar sands represent a tremendous untapped resource for transportation fuels. In the United States alone, over 60 billion barrels of bitumen are estimated to be in place. In order to use this bitumen, it must be somehow separated from the sand. The resulting bitumen is of low quality, and generally will require at least some refining. Typical refinery upgrading methods include fluid catalytic cracking, thermal visbreaking, and residuum hydroconversion. Most of these methods utilize metals-sensitive catalyst. The metals bound in the bitumen are deleterious to catalytic processing, causing rapid deactivation through poisoning and pore mouth plugging. Like heavy crude oil residua, tar sand bitumens have high concentrations of Ni and V. The types of complexes of Ni and V have been studied for heavy crude oils, and can be placed in two broad categories: the metallopetroporphyrins and the metallononporphyrins. The metallopetroporphyrins have been studied extensively. For understanding the behavior of the metals in processing, size exclusion chromatography coupled with element specific detection by inductively coupled plasma atomic emission spectroscopy (SEC-HPLC-ICP) has been applied to several heavy crude oils, residua, and processed products along with separated fractions of feeds and products. These results have shown general important size-behavior features of the metallopetroporphyrins and metallo-nonporphyrins associated with individual feed characteristics. Because of the importance of the metals in a downstream process methods, the authors have applied several of the metallopetroporphyrin and metallo-nonporphyrin examination technique to extracted bitumen from selected tar sands.

Water quality for secondary and tertiary oil recovery  

SciTech Connect (OSTI)

A key element in many secondary and tertiary oil recovery processes is the injection of water into an oil-bearing formation. Water is the fluid which displaces the oil in the pore space of the rock. A successful waterflood requires more than the availability of water and the pumps and piping to inject the water into the formation. It requires an understanding of how water enters the oil bearing formation and what happens once the injected water comes into contact with the rock or sand, the oil, and the water already in the reservoir. Problems in injectivity will arise unless care and constant monitoring are exercised in the water system for a flood operation. This study examines water availability and quality in relation to waterflooding.

Soil stabilization using oil-shale solid waste  

SciTech Connect (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.

Expectations for Oil Shale Production (released in AEO2009)  

Reports and Publications (EIA)

Oil shales are fine-grained sedimentary rocks that contain relatively large amounts of kerogen, which can be converted into liquid and gaseous hydrocarbons (petroleum liquids, natural gas liquids, and methane) by heating the rock, usually in the absence of oxygen, to 650 to 700 degrees Fahrenheit (in situ retorting) or 900 to 950 degrees Fahrenheit (surface retorting). (Oil shale is, strictly speaking, a misnomer in that the rock is not necessarily a shale and contains no crude oil.) The richest U.S. oil shale deposits are located in Northwest Colorado, Northeast Utah, and Southwest Wyoming. Currently, those deposits are the focus of petroleum industry research and potential future production. Among the three states, the richest oil shale deposits are on federal lands in northwest Colorado.

In situ retorting or oil shale  

SciTech Connect (OSTI)

An improved method of in situ retorting of oil shale wherein a cavern of crushed shale is created within an oil shale deposit, preferably by igniting a powerful explosion within the oil shale deposit, thereby creating a localized area or cavern of rubblized oil shale. Combustion gases are injected into the bottom of this cavern and particulate material, preferably a cracking catalyst, is deposited into a void at the top of the cavern and allowed to trickle down and fill the voids in the rubblized cavern. The oil shale is ignited at the bottom of the cavern and a combustion zone proceeds upwardly while the particulate material is caused by gas flow to percolate downwardly. A fluidized bed of particulate material is thereby formed at the combustion zone providing a controlled, evelny advancing combustion zone. This, in turn, efficiently retorts oil shale, provides increased recovery of hydrocarbon while ismultaneously producing a catalytically cracked volatile, high octane gasoline exiting from the top of the retort.

Solubility of carbon dioxide in tar sand bitumen; Experimental determination and modeling  

SciTech Connect (OSTI)

This paper reports on an understanding of the solubility of carbon dioxide (CO{sub 2}) in tar sand bitumen that is essential for the development of in situ processes in the recovery of bitumen from tar and deposits. The solubility of CO{sub 2} in the Tar Sand Triangle (Utah), the PR Spring Rainbow I (Utah), and the Athabasca (Canada) tar sand bitumens was determined with the use of a high-pressure microbalance at temperatures of 358.2 and 393.2 K and pressures up to 6.2 MPa. As expected, the solubilities increased with pressure at a given temperature and decreased with increases in temperature. The Peng--Robinson and the Schmidt--Wenzel equations of state were used to match the experimentally observed solubilities. Correlations for the interaction parameters between CO{sub 2} and the bitumen were developed for both equations of state, wherein the interaction parameter could be obtained by using specific gravity and the UOP {ital K} factor for the bitumen. The correlations were developed with the optimum interaction parameters obtained for each of the samples at each temperature.

Global Sea Level Stabilization-Sand Dune Fixation: A Solar-powered Sahara Seawater Textile Pipeline  

E-Print Network [OSTI]

Could anthropogenic saturation with pumped seawater of the porous ground of active sand dune fields in major deserts (e.g., the westernmost Sahara) cause a beneficial reduction of global sea level? Seawater extraction from the ocean, and its deposition on deserted sand dune fields in Mauritania and elsewhere via a Solar-powered Seawater Textile Pipeline (SSTP) can thwart the postulated future global sea level. Thus, Macro-engineering offers an additional cure for anticipated coastal change, driven by global sea level rise, that could supplement, or substitute for (1) stabilizing the shoreline with costly defensive public works (armoring macroprojects) and (2) permanent retreat from the existing shoreline (real and capital property abandonment). We propose Macro-engineering use tactical technologies that sculpt and vegetate barren near-coast sand dune fields with seawater, seawater that would otherwise, as commonly postulated, enlarge Earth seascape area! Our Macro-engineering speculation blends eremology with hydrogeology and some hydromancy. We estimate its cost at 1 billion dollars - about 0.01 per sent of the USA 2007 Gross Domestic Product.

Beginning of an oil shale industry in Australia  

SciTech Connect (OSTI)

This paper discusses how preparations are being made for the construction and operation of a semi commercial plant to process Australian oil shale. This plant is primarily designed to demonstrate the technical feasibility of processing these shales at low cost. Nevertheless it is expected to generate modest profits even at this demonstration level. This will be the first step in a three staged development of one of the major Australian oil shale deposits which may ultimately provide nearly 10% of Australia's anticipated oil requirements by the end of the century. In turn this development should provide the basis for a full scale oil shale industry in Australia based upon the advantageously disposed oil shale deposits there. New sources of oil are becoming critical since Australian production is declining rapidly while consumption is accelerating.

The potential use of tar sand bitumen as paving asphalt  

SciTech Connect (OSTI)

The properties of several tar sand asphalts prepared in past studies by several different investigators were compared with each other and with the properties of petroleum asphalts. These results were reviewed and discussed with regard to the potential use of tar sand bitumen in pavement applications. The data show that tar sand bitumen has good potential for use in highway pavements that meet today's performance specifications. No deficiencies in the tar sand asphalts were found that would be expected to seriously affect performance. On the other hand, the data indicate that some tar sand asphalts may have superior aging characteristics, being relatively resistant to oxidative age hardening compared with typical petroleum asphalts. Asphalt-aggregate mixtures prepared using two tar sand asphalts also showed acceptable strength properties and excellent resistance to moisture-induced damage.

Hydrotreating of oil from eastern oil shale  

SciTech Connect (OSTI)

Oil shale provides one of the major fossil energy reserves for the United States. The quantity of reserves in oil shale is less than the quantity in coal, but is much greater (by at least an order of magnitude) than the quantity of crude oil reserves. With so much oil potentially available from oil shale, efforts have been made to develop techniques for its utilization. In these efforts, hydrotreating has proved to be an acceptable technique for upgrading raw shale oil to make usuable products. The present work demonstrated the use of the hydrotreating technique for upgrading an oil from Indiana New Albany oil shale.

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

SciTech Connect (OSTI)

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.

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.

TESTING OF TMR SAND MANTIS FINAL REPORT  

SciTech Connect (OSTI)

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.

Solvent extraction of bitumen from tar sands  

SciTech Connect (OSTI)

This paper reports on the measurement of mass transfer rates for the extraction of bitumen from tar sands using organic solvents. The experiment was carried out in an agitated vessel using a six-blade turbine mixer on a laboratory scale. To facilitate the determination of absolute mass transfer coefficients, tar sands were specially prepared in the form of spherical particles so that mass transfer area can be computed. The variables investigated in the study included: (1) solvent type (kerosene, toluene, benzene), (2) stirrer speed, 25 rpm to 1000 rpm, and (3) particle diameter, 0.4 cm to 1.2 cm. The results indicated that solvency power varied markedly with the various solvents used and that high aromatic content promoted rapid dissolution when compared with paraffinic solvents. The mass transfer rates increased with increasing stirrer speed in accordance with the relationship: k {alpha} N{sup 0.56} where k is the mass transfer coefficient and N the stirrer speed. Increasing particle diameter also resulted in decreased mass transfer rates. The results were satisfactorily correlated in terms of a Frossling type equation, Sh {alpha} Re{sub p}{sup a}Sc{sup b}.

Shallow oil production using horizontal wells with enhanced oil recovery techniques  

SciTech Connect (OSTI)

Millions of barrels of oil exist in the Bartlesville formation throughout Oklahoma, Kansas, and Missouri. In an attempt to demonstrate that these shallow heavy oil deposits can be recovered, a field project was undertaken to determine the effectiveness of enhanced oil recovery techniques (EOR) employing horizontal wells. Process screening results suggested that thermal EOR processes were best suited for the recovery of this heavy oil. Screening criteria suggested that in situ combustion was a viable technique for the production of these reserves. Laboratory combustion tube tests confirmed that sufficient amounts of fuel could be deposited. The results of the in situ combustion field pilot were disappointing. A total overall recovery efficiency of only 16.0 percent was achieved. Results suggest that the combustion front might have moved past the horizontal well, however elevated temperatures or crude upgrading were not observed. Factors contributing to the lack of production are also discussed.

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 (OSTI)

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.

Tight gas sands study breaks down drilling and completion costs  

SciTech Connect (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.

DEVELOPMENT OF BYPASSED OIL RESERVES USING BEHIND CASING RESISTIVITY MEASUREMENTS  

SciTech Connect (OSTI)

Tubing and rods of the S.P. Pedro-Nepple No.1 well were pulled and the well was prepared for running of Schlumberger's Cased Hole Formation Resistivity Tool (CHFR) in selected intervals. The CHFR tool was successfully run and data was captured. The CHFR formation resistivity readings were compared to original open hole resistivity measurements. Separation between the original and CHFR resistivity curves indicate both swept and un-swept sand intervals. Both watered out sand intervals and those with higher remaining oil saturation have been identified. Due to the nature of these turbidite sands being stratigraphically continuous, both the swept and unswept layers have been correlated across to one of the four nearby offset shallow wells. As a result of the cased hole logging, one well was selected for a workover to recomplete and test suspected oil saturated shallow sand intervals. Well S.P. Pedro-Nepple No.2 was plugged back with cement excluding the previously existing production interval, squeeze cemented behind casing, selectively perforated in the shallower ''Bell'' zone and placed on production to develop potential new oil reserves and increase overall well productivity. Prior workover production averaged 3.0 BOPD for the previous six-months from the original ''Meyer'' completion interval. Post workover well production was increased to 5.3 BOPD on average for the following fifteen months. In December 2005, a bridge plug was installed above the ''Bell'' zone to test the ''Foix'' zone. Another cement squeeze was performed behind casing, selectively perforated in the shallower ''Foix'' zone and placed on production. The ''Foix'' test has produced water and a trace of oil for two months.

Enzymes have been previously used as gel breakers. In these applications, the enzyme removes a chemical which is no longer required, such as biopolymers in filter cakes after drilling or in frac gels after the frac has occurred. Enzymes are now used to produce useful oilfield chemicals in-situ for acidizing, sand consolidation and water shutoff applications. Enzyme-based processes for generating other useful oil-field chemicals, including minerals, gels and resins, are being developed, and these applications 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  

SciTech Connect (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.

Pyrolysis of shale oil vacuum distillate fractions  

SciTech Connect (OSTI)

The freezing point of US Navy jet fuel (JP-5) has been related to the amounts of large n-alkanes present in the fuel. This behavior applies to jet fuels derived from alternate fossil fuel resources, such as shale oil, coal, and tar sands, as well as those derived from petroleum. In general, jet fuels from shale oil have the highest and those from coal the lowest n-alkane content. The origin of these n-alkanes in the amounts observed, especially in shale-derived fuels, is not readily explained on the basis of literature information. Studies of the processes, particularly the ones involving thermal stress, used to produce these fuels are needed to define how the n-alkanes form from larger molecules. The information developed will significantly contribute to the selection of processes and refining techniques for future fuel production from shale oil. Carbon-13 nmr studies indicate that oil shale rock contains many long unbranched straight chain hydrocarbon groups. The shale oil derived from the rock also gives indication of considerable straight chain material with large peaks at 14, 23, 30, and 32 ppM in the C-13 nmr spectrum. Previous pyrolysis studies stressed fractions of shale crude oil residua, measured the yields of JP-5, and determined the content of potential n-alkanes in the JP-5 distillation range (4). In this work, a shale crude oil vacuum distillate (Paraho) was separated into three chemical fractions. The fractions were then subjected to nmr analysis to estimate the potential for n-alkane production and to pyrolysis studies to determine an experimental n-alkane yield.

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

SciTech Connect (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.

Economic and ecological preconditions are considered for the transition from monoproduct oil shale mining to polyproduct Estonian oil shale deposits. Underground water, limestone, and underground heat found in oil shale mines with small reserves can be operated for a long time using chambers left after oil shale extraction. The adjacent fields of the closed mines can be connected to the operations of the mines that are still working. Complex usage of natural resources of Estonian oil shale deposits is made possible owing to the unique features of its geology and technology. Oil shale seam development is carried out at shallow depths (40--70 m) in stable limestones and does not require expensive maintenance. Such natural resources as underground water, carbonate rocks, heat of rock mass, and underground chambers are opened by mining and are ready for utilization. Room-and-pillar mining does not disturb the surface, and worked oil shale and greenery waste heaps do not breach its ecology. Technical decisions and economic evaluation are presented for the complex utilization of natural resources in the boundaries of mine take of the ``Tammiku`` underground mine and the adjacent closed mine N2. Ten countries have already experienced industrial utilization of oil shale in small volumes for many years. Usually oil shale deposits are not notable for complex geology of the strata and are not deeply bedded. Thus complex utilization of quite extensive natural resources of Estonian oil shale deposits is of both scientific and practical interest.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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 (OSTI)

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.

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

SciTech Connect (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.

Horizontal low-void retorting of eastern and western oil shale  

SciTech Connect (OSTI)

Horizontal in situ retorting processes have been developed to recover oil from thin, shallow oil shale deposits. To date the most successful field tests have been conducted in Green River oil shale located in Utah. Consideration is being given to applying this technology to the New Albany oil shales in Indiana. Western Research Institute (WRI) conducted two horizontal in situ oil shale experiments using eastern oil shale and the results are compared with results obtained from a similar experiment using Green River oil shale. The objectives of the three experiments were to simulate the horizontal retorting process and determine oil yield, retorting zone profiles and product characteristics using alternative operating conditions for eastern and western oil shales. The tests proved that horizontal retorting could be simulated in the laboratory. However, air bypass problems occurred in the experiments, which probably reduced oil recovery compared with recovery from field tests. During the eastern oil shale tests plugging was encountered in the gas recovery system because of the production of a solid material containing sulfur compounds. This plugging could be a potential problem for future laboratory and field experimentation. The oil produced from eastern oil shale has different properties from western shale oil. The oil is highly aromatic and when hydrogenated may yield a prototype high density jet fuel. 10 refs., 8 figs., 11 tabs.

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

SciTech Connect (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 waterflood reserves in the Wilmington Oil Field through improved reservoir characterization and reservoir management. Annual report, March 21, 1995--March 20, 1996  

SciTech Connect (OSTI)

This project uses 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 saturation sands will be stimulated by recompleting existing production and injection wells in these sands using conventional means as well as short radius and ultra-short radius laterals. 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.

The extraction of bitumen from western tar sands  

SciTech Connect (OSTI)

This report represents the work done during the year of May 8, 1987 to June 9, 1988. This year was the first year of a five-year program. The overall objective of the latter is to advance the technologies for recovering bitumen from the tar sands by thermal and water assisted extraction means and upgrading of bitumen to synthetic crude, and conversion of bitumens to specialty products such as asphalt and resins to levels where realistic evaluations of technical and commercial potential can be made. Additionally, it is desired to have the data at a level which is adequate for design of pilot plants of appropriate size deemed necessary for commercial scale-up of the various processes being studied. The main areas for studies covered in this report are modelling and optimization of the hydropyrolysis process for upgrading bitumens, bitumen recovery by pyrolysis of the circle Cliffs tar sands in a fluid bed, pyrolysis of Whiterocks tar sand in a rotary kiln, modelling of the combustor in the coupled fluidized bed with interbed heat transfer using heat pipes, development of superior diluents for use in the water extraction of Utah's tar sands, and fractionation and characterization of the bitumens from Asphalt Ridge and Sunnyside tar sands. 169 refs., 60 figs., 31 tars.

Chemistry of sands from the modern Indus River and the Archean Witwatersrand basin: Implications for the composition of the Archean atmosphere  

SciTech Connect (OSTI)

Both the Indus River and the Witwatersrand basin contain sand with grains of detrital uraninite. Because this mineral is easily oxidized, its presence in Archean strata as a detrital particle has been used as evidence for a low-oxygen atmosphere before 2.5 Ga. However, its presence in modern sand from the Indus River system has been used to argue that detrital uraninite does not provide information about the oxygen concentration of Earth's early atmosphere. Petrographic and chemical study of sand from these two sources reveals differences that suggest the modern Indus sand cannot be used as an analog for the Archean Witwatersrand occurrences. The Witwatersrand quartzites are depleted in Ca, Mg, and Na, indicating that the original sand from which they formed had been subjected to intense weathering. The chemical index of alteration (CIA), a commonly used indicator of degree of weathering, yields an average value of about 0.80 for Witwatersrand quartzites, comparable to modern tropical streams such as the Orinoco that drain deeply weathered terrains under tropical conditions (CIA=0.75). In contrast, the CIA for Indus sand is 0.45, indicating virtually no chemical weathering. The significance of Archean quartz-pebble conglomerates is not just that they contain unstable detrital phases like uraninite and pyrite, but that these particles are associated with rocks whose compositions suggest intense weathering. These conglomerates must have been subjected to intense weathering under tropical conditions, either in their source area or at the site of deposition, and the preservation of minerals like uraninite such conditions is indeed strong evidence for a low-oxygen atmosphere.

Feasibility study of heavy oil recovery in the Appalachian, Black Warrior, Illinois, and Michigan basins  

SciTech Connect (OSTI)

This report is one of a series of publications assessing the feasibility of increasing domestic heavy oil production. Each report covers select areas of the United States. The Appalachian, Black Warrior, Illinois, and Michigan basins cover most of the depositional basins in the Midwest and Eastern United States. These basins produce sweet, paraffinic light oil and are considered minor heavy oil (10{degrees} to 20{degrees} API gravity or 100 to 100,000 cP viscosity) producers. Heavy oil occurs in both carbonate and sandstone reservoirs of Paleozoic Age along the perimeters of the basins in the same sediments where light oil occurs. The oil is heavy because escape of light ends, water washing of the oil, and biodegradation of the oil have occurred over million of years. The Appalachian, Black Warrior, Illinois, and Michigan basins` heavy oil fields have produced some 450,000 bbl of heavy oil of an estimated 14,000,000 bbl originally in place. The basins have been long-term, major light-oil-producing areas and are served by an extensive pipeline network connected to refineries designed to process light sweet and with few exceptions limited volumes of sour or heavy crude oils. Since the light oil is principally paraffinic, it commands a higher price than the asphaltic heavy crude oils of California. The heavy oil that is refined in the Midwest and Eastern US is imported and refined at select refineries. Imports of crude of all grades accounts for 37 to >95% of the oil refined in these areas. Because of the nature of the resource, the Appalachian, Black Warrior, Illinois and Michigan basins are not expected to become major heavy oil producing areas. The crude oil collection system will continue to degrade as light oil production declines. The demand for crude oil will increase pipeline and tanker transport of imported crude to select large refineries to meet the areas` liquid fuels needs.

The crude oil collection system will continue to degrade as light oil production declines. The demand for crude oil will increase pipeline and tanker transport of imported crude to select large refineries to meet the areas' liquid fuels needs.

Investigation of guided waves propagation in pipe buried in sand  

SciTech Connect (OSTI)

The inspection of pipelines by guided wave testing is a well-established method for the detection of corrosion defects in pipelines, and is currently used routinely in a variety of industries, e.g. petrochemical and energy. When the method is applied to pipes buried in soil, test ranges tend to be significantly compromised because of attenuation of the waves caused by energy radiating into the soil. Moreover, the variability of soil conditions dictates different attenuation characteristics, which in-turn results in different, unpredictable, test ranges. We investigate experimentally the propagation and attenuation characteristics of guided waves in pipes buried in fine sand using a well characterized full scale experimental apparatus. The apparatus consists of an 8 inch-diameter, 5.6-meters long steel pipe embedded over 3 meters of its length in a rectangular container filled with fine sand, and an air-bladder for the application of overburden pressure. Longitudinal and torsional guided waves are excited in the pipe and recorded using a transducer ring (Guided Ultrasonics Ltd). Acoustic properties of the sand are measured independently in-situ and used to make model predictions of wave behavior in the buried pipe. We present the methodology and the systematic measurements of the guided waves under a range of conditions, including loose and compacted sand. It is found that the application of overburden pressure modifies the compaction of the sand and increases the attenuation, and that the measurement of the acoustic properties of sand allows model prediction of the attenuation of guided waves in buried pipes with a high level of confidence.

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

SciTech Connect (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.

Utilization of Estonian oil shale at power plants  

SciTech Connect (OSTI)

Estonian oil shale belongs to the carbonate class and is characterized as a solid fuel with very high mineral matter content (60--70% in dry mass), moderate moisture content (9--12%) and low heating value (LHV 8--10 MJ/kg). Estonian oil shale deposits lie in layers interlacing mineral stratas. The main constituent in mineral stratas is limestone. Organic matter is joined with sandy-clay minerals in shale layers. Estonian oil shale at power plants with total capacity of 3060 MW{sub e} is utilized in pulverized form. Oil shale utilization as fuel, with high calcium oxide and alkali metal content, at power plants is connected with intensive fouling, high temperature corrosion and wear of steam boiler`s heat transfer surfaces. Utilization of Estonian oil shale is also associated with ash residue use in national economy and as absorbent for flue gas desulfurization system.

Effect of oil pollution on fresh groundwater in Kuwait  

SciTech Connect (OSTI)

Massive oil fires in Kuwait were the aftermath of the Gulf War. This resulted in the pollution of air, water, and soil, the magnitude of which is unparalleled in the history of mankind. Oil fires damaged several oil well heads, resulting in the flow of oil, forming large oil lakes. Products of combustion from oil well fires deposited over large areas. Infiltrating rainwater, leaching out contaminants from oil lakes and products of combustion at ground surface, can reach the water table and contaminate the groundwater. Field investigations, supported by laboratory studies and mathematical models, show that infiltration of oil from oil lakes will be limited to a depth of about 2 m from ground surface. Preliminary mathematical models showed that contaminated rainwater can infiltrate and reach the water table within a period of three to four days, particularly at the Raudhatain and Umm Al-Aish regions. These are the only regions in Kuwait where fresh groundwater exists. After reaching the water table, the lateral movement of contaminants is expected to be very slow under prevailing hydraulic gradients. Groundwater monitoring at the above regions during 1992 showed minor levels of vanadium, nickel, and total hydrocarbons at certain wells. Since average annual rainfall in the region is only 120 mm/yr, groundwater contamination due to the infiltration of contaminated rainwater is expected to be a long-term one. 13 refs., 15 figs., 2 tabs.

Literature survey and documentation on organic solid deposition problem. Status report  

SciTech Connect (OSTI)

Organic solid deposition is often a major problem in petroleum production and processing. Recently, this problem has attracted more attention because operating costs have become more critical to the profit of oil production. Also, in miscible gas flooding, asphaltene deposition often occurs in the wellbore region after gas breakthrough and causes plugging. The organic deposition problem is particularly serious in offshore oil production. Cooling of crude oil when it flows through long-distance pipelines under sea water may cause organic deposition in the pipeline and result in plugging. NIPER`s Gas EOR Research Project has been devoted to the study of the organic solid deposition problem for three years. NIPER has received many requests for technical support. Recently, the DeepStar project committee on thermo-technology development and standardization has asked NIPER to provide them with NIPER`s expertise and experience. To assist the oil industry, NIPER is preparing a state-of-the-art review on the technical development for the organic deposition problem. In the first quarter, this project has completed a literature survey and documentation. total of 258 publications (114 for wax, 124 for asphaltene, and 20 for related subjects) were collected and categorized. This literature survey was focused on the two subjects: wax and asphaltene. The subjects of bitumen, asphalt, and heavy oil are not included. Also, the collected publications are mostly related to production problems.

Characterization of nickel and vanadium compounds in tar sand bitumen by petroporphyrin quantitation and size exclusion chromatography coupled with element specific detection  

SciTech Connect (OSTI)

Previously, we have 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-nonporphyrins/--/each having unique reactivity during processing. In efforts to better understand the binding of metals in the oil medium, we have now examined Ni and V in tar sand bitumens. The bitumen was solvent extracted from the sand matrix and was separated by column chromatography to quantitate petroporphyrin content. 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. Size characteristic profiles (SEC-HPLC-ICP) were generated for the extracted bitumens. The profiles are generally bimodal in shape and resemble several different specific heavy crude oils and residua. For examples, Arroyo Grande and McKittrick appear to be similar to Kern River (California) 650/degree/F+ residuum, while Athabasca resembles Morichal (Venezuela) 650/degree/F+ residuum. These results will be discussed in terms of generalized profile and petroporphyrin behavior. 23 refs., 3 figs., 3 tabs.

Conversion characteristics of 10 selected oil shales  

SciTech Connect (OSTI)

The conversion behavior of 10 oil shale from seven foreign and three domestic deposits has been studied by combining solid- and liquid-state nuclear magnetic resonance (NMR) measurements with material balance Fischer assay conversion data. The extent of aromatization of aliphatic carbons was determined. Between zero and 42% of the raw shale aliphatic carbon formed aromatic carbon during Fischer assay. For three of the shales, there was more aromatic carbon in the residue after Fisher assay than in the raw shale. Between 10 and 20% of the raw shale aliphatic carbons ended up as aliphatic carbons on the spent shale. Good correlations were found between the raw shale aliphatic carbon and carbon in the oil and between the raw shale aromatic carbon and aromatic carbon on the spent shale. Simulated distillations and molecular weight determinations were performed on the shale oils. Greater than 50% of the oil consisted of the atmospheric and vacuum gas oil boiling fractions. 14 refs., 15 figs., 1 tab.

DEVELOPMENT OF BIOSURFACTANT-MEDIATED OIL RECOVERY IN MODEL POROUS SYSTEMS AND COMPUTER SIMULATIONS OF BIOSURFACTANT-MEDIATED OIL RECOVERY  

SciTech Connect (OSTI)

Current technology recovers only one-third to one-half of the oil that is originally present in an oil reservoir. Entrapment of petroleum hydrocarbons by capillary forces is a major factor that limits oil recovery (1, 3, 4). Hydrocarbon displacement can occur if interfacial tension (IFT) between the hydrocarbon and aqueous phases is reduced by several orders of magnitude. Microbially-produced biosurfactants may be an economical method to recover residual hydrocarbons since they are effective at low concentrations. Previously, we showed that substantial mobilization of residual hydrocarbon from a model porous system occurs at biosurfactant concentrations made naturally by B. mojavensis strain JF-1 if a polymer and 2,3-butanediol were present (2). In this report, we include data on oil recovery from Berea sandstone experiments along with our previous data from sand pack columns in order to relate biosurfactant concentration to the fraction of oil recovered. We also investigate the effect that the JF-2 biosurfactant has on interfacial tension (IFT). The presence of a co-surfactant, 2,3-butanediol, was shown to improve oil recoveries possibly by changing the optimal salinity concentration of the formulation. The JF-2 biosurfactant lowered IFT by nearly 2 orders of magnitude compared to typical values of 28-29 mN/m. Increasing the salinity increased the IFT with or without 2,3-butanediol present. The lowest interfacial tension observed was 0.1 mN/m. Tertiary oil recovery experiments showed that biosurfactant solutions with concentrations ranging from 10 to 60 mg/l in the presence of 0.1 mM 2,3-butanediol and 1 g/l of partially hydrolyzed polyacrylamide (PHPA) recovered 10-40% of the residual oil present in Berea sandstone cores. When PHPA was used alone, about 10% of the residual oil was recovered. Thus, about 10% of the residual oil recovered in these experiments was due to the increase in viscosity of the displacing fluid. Little or no oil was recovered at biosurfactant concentrations below the critical micelle concentration (about 10 mg/l). Below this concentration, the IFT values were high. At biosurfactant concentrations from 10 to 40 mg/l, the IFT was 1 mN/m. As the biosurfactant concentration increased beyond 40 mg/l, IFT decreased to about 0.1 mN/m. At biosurfactant concentrations in excess of 10 mg/l, residual oil recovery was linearly related to biosurfactant concentration. A modified mathematical model that relates oil recovery to biosurfactant concentration adequately predicted the experimentally observed changes in IFT as a function of biosurfactant concentration.

Heavy oil reservoirs recoverable by thermal technology. Annual report  

SciTech Connect (OSTI)

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.

This patent describes a process for recovering bitumen from tar sand which comprises: (a) preparing a mixture containing divided tar sand and an organic solvent the ratio of the solvent to the bitumen in the tar sand is at least 2 parts solvent to 1 part bitumen form a bitument/solvent phase with a viscosity low enough to facilitate the physical separation of a significant portion of the bitumen/solvent phase from the mineral matrix of the tar sand; (b) separating by physical means at least a portion of the bitumen/solvent phase from the mineral matrix; (c) mixing the separated mineral matrix of step (b) with additional solvent in a washing stage to recover bitumen remaining with the mineral matrix; (d) introducing the recovered solvent/bitumen mixture from wash step (c) back into step (a); (e) recovering organic solvent from the mineral matrix of step (c) using an aqueous/organic solvent froth flotation phase separation where the majority of the mineral matrix remains with the aqueous phase; (f) recycling the solvent recovered from the phase separation of step (e) back to the washing step of (c); (g) separating bitumen from the bitumen/solvent phase of step (b); and (h) returning solvent collected from step (g) back to step (a).
