PROCESSING OF MONAZITE SAND  

DOE Patents (OSTI)

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

Sand consolidation method  

SciTech Connect

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

METHOD OF PROCESSING MONAZITE SAND  

DOE Patents (OSTI)

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

TESTING OF TMR SAND MANTIS FINAL REPORT  

SciTech Connect

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

Sand consolidation method employing latex  

SciTech Connect

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

METHOD OF PROCESSING MONAZITE SAND  

DOE Patents (OSTI)

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

Recent government efforts regarding tar sands  

SciTech Connect

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

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

SciTech Connect

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

Sand-control alternatives for horizontal wells  

SciTech Connect

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

Frame moduli of unconsolidated sands and sandstones  

SciTech Connect

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

Sand control method employing special hydraulic fracturing technique  

SciTech Connect

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

Granular size segregation in underwater sand ripples  

E-Print Network (OSTI)

We report an experimental study of a binary sand bed under an oscillating water flow. The formation and evolution of ripples is observed. The appearance of a granular segregation is shown to strongly depend on the sand bed preparation. The initial wavelength of the mixture is measured. In the final steady state, a segregation in volume is observed instead of a segregation at the surface as reported before. The correlation between this phenomenon and the fluid flow is emphasised. Finally, different ``exotic'' patterns and their geophysical implications are presented.

Imaging of Acoustic Waves in Sand  

SciTech Connect

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

Solvent extraction of Southern US tar sands  

SciTech Connect

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

Western gas sands: Technology status report  

Science Conference Proceedings (OSTI)

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

Policy Analysis of the Canadian Oil Sands Experience  

SciTech Connect

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

Unconsolidated sand grain shape, size impact frac-pack design  

SciTech Connect

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

Flotation behavior of digested asphalt ridge tar sands  

SciTech Connect

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

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...

Tight gas sands study breaks down drilling and completion costs  

Science Conference Proceedings (OSTI)

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

Direct Production of Silicones From Sand  

Science Conference Proceedings (OSTI)

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

Acoustic sand detector for fluid flowstreams  

DOE Patents (OSTI)

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

Sand control in horizontal wells in heavy-oil reservoirs  

SciTech Connect

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

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.

The apparent surface roughness of moving sand transported by wind  

E-Print Network (OSTI)

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

GASIFICATION IN THE CANADIAN OIL SANDS:  

E-Print Network (OSTI)

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

Getty mines oil sands in California  

Science Conference Proceedings (OSTI)

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

The effects of psammophilous plants on sand dune dynamics  

E-Print Network (OSTI)

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

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

Method of tagging sand with ruthenium-103 and the resultant product  

DOE Patents (OSTI)

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

Mechanism of acoustic emissions from booming sand dunes  

E-Print Network (OSTI)

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

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

Science Conference Proceedings (OSTI)

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

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

SciTech Connect

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

Shredded tires and rubber-sand as lightweight backfill  

Science Conference Proceedings (OSTI)

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

Method for diverting a gaseous sand-consolidating fluid  

SciTech Connect

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

Project Drum Inlet: explosive excavation in saturated sand  

SciTech Connect

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

Improved core recovery in laminated sand and shale sequences  

SciTech Connect

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

Canyon dissolution of sand, slag, and crucible residues  

Science Conference Proceedings (OSTI)

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

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

Science Conference Proceedings (OSTI)

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

Non-Darcy flow analysis through tight sand formations  

SciTech Connect

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

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

CO{sub 2}/sand fracturing in Devonian shales  

Science Conference Proceedings (OSTI)

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

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

SciTech Connect

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

Methane hydrate distribution from prolonged and repeated formation in natural and compacted sand samples: X-ray CT observations  

SciTech Connect

To study physical properties of methane gas hydrate-bearing sediments, it is necessary to synthesize laboratory samples due to the limited availability of cores from natural deposits. X-ray computed tomography (CT) and other observations have shown gas hydrate to occur in a number of morphologies over a variety of sediment types. To aid in understanding formation and growth patterns of hydrate in sediments, methane hydrate was repeatedly formed in laboratory-packed sand samples and in a natural sediment core from the Mount Elbert Stratigraphic Test Well. CT scanning was performed during hydrate formation and decomposition steps, and periodically while the hydrate samples remained under stable conditions for up to 60 days. The investigation revealed the impact of water saturation on location and morphology of hydrate in both laboratory and natural sediments during repeated hydrate formations. Significant redistribution of hydrate and water in the samples was observed over both the short and long term.

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

Science Conference Proceedings (OSTI)

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

Hydraulic fracturing with a refractory proppant for sand control  

SciTech Connect

A sand control and heat transfer method is described for use in a borehole having an unconsolidated or loosely consolidated oil or gas reservoir which is otherwise likely to introduce substantial amounts of sand into the borehole, comprising: (a) providing a borehole casing through the reservoir; (b) perforating the casing at preselected intervals therealong to form at least one of longitudinal, in-line perforations; (c) hydraulically fracturing the reservoir by injecting a fracturing fluid containing a fine grain fused refractory material which comprises substantially silicon carbide or silicon nitride, and a clay stabilizing agent; (d) injecting a proppant comprising a gravel packing fused refractory material comprised substantially of silicon carbide or silicon nitride into the fracture, whereby a first layer of fine grain fused refractory material is held in place along the entire face of the fracture by a second layer of gravel packing fused refractory material also extending along the entire length of the fracture thereby excluding fines; and (e) producing oil or gas from the reservoir through the fracture into the borehole casing via a thermal oil recovery method which proppant and layers provide for increased heat transfer into the formation.

Trace metals in heavy crude oils and tar sand bitumens

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

Preliminary relative permeability estimates of methanehydrate-bearing sand  

Science Conference Proceedings (OSTI)

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

Retention behavior of dilute polymers in oil sands  

Science Conference Proceedings (OSTI)

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

Magnet Coil Shorted Turn Detector  

Science Conference Proceedings (OSTI)

The Magnet Coil Shorted Turn Detector has been developed to facilitate the location of shorted turns in magnet coils. Finding these shorted turns is necessary to determine failure modes that are a necessary step in developing future production techniques. Up to this point, coils with shorted turns had the insulation burned off without the fault having been located. This disassembly process destroyed any chance of being able to find the fault. In order to maintain a flux balance in a coupled system such as a magnet coil, the current in a shorted turn must be opposed to the incident current. If the direction of the current in each conductor can be measured relative to the incident current, then the exact location of the short can be determined. In this device, an AC voltage is applied to the magnet under test. A small hand held B-dot pickup coil monitors the magnetic field produced by current in the individual magnet conductors. The relative phase of this pickup coil voltage is compared to a reference signal derived from the input current to detect a current reversal as the B-dot pickup coil is swept over the conductors of the coil under test. This technique however, is limited to only those conductors that are accessible to the hand held probe.

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

E-Print Network (OSTI)

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

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

SciTech Connect

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

CAVITY LIKE COMPLETIONS IN WEAK SANDS PREFERRED UPSTREAM MANAGEMENT PRACTICES  

SciTech Connect

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

Engineering assessment of radioactive sands and residues, Lowman Site, Lowman, Idaho  

SciTech Connect

Ford, Bacon and Davis Utah Inc. has reevaluated the Lowman site in order to revise the December 1977 engineering assessment of the problems resulting from the existence of radioactive sands and residues at Lowman, Idaho. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of radioactive sands and residues and radiation exposure of individuals and nearby populations, and investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 191,000 tons of radioactive sands, residues, and contaminated soils at the Lowman site constitutes the most significant environmental impact, although windblown radioactive sands and external gamma radiation also are factors.

Determination of soil liquefaction characteristics by large-scale laboratory tests. [Sand  

SciTech Connect

The testing program described in this report was carried out to study the liquefaction behavior of a clean, uniform, medium sand. Horizontal beds of this sand, 42 inches by 90 inches by 4 inches were prepared by pluviation with a special sand spreader, saturated, and tested in a shaking table system designed for this program, which applied a horizontal cyclic shear stress to the specimens. Specimen size was selected to reduce boundary effects as much as possible. Values of pore pressures and shear strains developed during the tests are presented for sand specimens at relative densities of 54, 68, 82, and 90 percent, and the results interpreted to determine the values of the stress ratio causing liquefaction at the various relative densities.

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

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

Science Conference Proceedings (OSTI)

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

Unsaturated hydraulic conductivity of compacted sand-kaolin mixtures  

SciTech Connect

The unsaturated hydraulic conductivity of compacted sand-kaolin mixtures containing 0, 5, 10, and 30% kaolin (by dry weight) is measured for matric suctions, {psi}{sub m} < {approximately} 6.0 m. The measured unsaturated hydraulic conductivity (k{sub m}) values are compared with predicted unsaturated hydraulic conductivity (k{sub p}) values using the Brooks-Corey-Burdine and van Genuchten-Mualem relative hydraulic conductivity functions. In general, the accuracy of k{sub p} decreases with an increase in kaolin content or an increase in {psi}{sub m}. In addition, k{sub m} tends to be underpredicted for kaolin contents of 10 and 30% at relatively high suctions (1.0 m {le} {psi}{sub m} {le} 6.0 m) and overpredicted for kaolin contents of 0 and 5% at relatively low suctions (0.1 m {le} {psi}{sub m} < 1.0 m). For a given kaolin content and {psi}{sub m}, k{sub p} based on the Brooks-Corey-Burdine function tends to be more accurate than k{sub m} based on the van Genuchten-Mualem function. Finally, for 1.0 m {le} {psi}{sub m} {le} 6.0 m, k{sub p} based on analysis using the maximum volumetric water content ({theta}{sub m}) attained under steady-state flow conditions typically is more accurate than k{sub p} based on analysis using the saturated volumetric water content, {theta}{sub s}, where {theta}{sub m} {approximately} 84--90% of {theta}{sub s} in this study.

FIELD TESTING & OPTIMIZATION OF CO2/SAND FRACTURING TECHNOLOGY  

SciTech Connect

These contract efforts involved the demonstration of a unique liquid free stimulation technology which was, at the beginning of these efforts, in 1993 unavailable in the US. The process had been developed, and patented in Canada in 1981, and held promise for stimulating liquid sensitive reservoirs in the US. The technology differs from that conventionally used in that liquid carbon dioxide (CO{sub 2}), instead of water is the base fluid. The CO{sub 2} is pumped as a liquid and then vaporizes at reservoir conditions, and because no other liquids or chemicals are used, a liquid free fracture is created. The process requires a specialized closed system blender to mix the liquid CO{sub 2} with proppant under pressure. These efforts were funded to consist of up to 21 cost-shared stimulation events. Because of the vagaries of CO{sub 2} supplies, service company support and operator interest only 19 stimulation events were performed in Montana, New Mexico, and Texas. Final reports have been prepared for each of the four demonstration groups, and the specifics of those demonstrations are summarized. A summary of the demonstrations of a novel liquid-free stimulation process which was performed in four groups of ''Candidate Wells'' situated in Crockett Co., TX; San Juan Co., NM; Phillips Co., MT; and Blaine Co., MT. The stimulation process which employs CO{sub 2} as the working fluid and the production responses were compared with those from wells treated with conventional stimulation technologies, primarily N{sub 2} foam, excepting those in Blaine Co., MT where the reservoir pressure is too low to clean up spent stimulation liquids. A total of 19 liquid-free CO{sub 2}/sand stimulations were performed in 16 wells and the production improvements were generally uneconomic.

Dynamic Behavior of Sand: Annual Report FY 11  

SciTech Connect

Currently, design of earth-penetrating munitions relies heavily on empirical relationships to estimate behavior, making it difficult to design novel munitions or address novel target situations without expensive and time-consuming full-scale testing with relevant system and target characteristics. Enhancing design through numerical studies and modeling could help reduce the extent and duration of full-scale testing if the models have enough fidelity to capture all of the relevant parameters. This can be separated into three distinct problems: that of the penetrator structural and component response, that of the target response, and that of the coupling between the two. This project focuses on enhancing understanding of the target response, specifically granular geomaterials, where the temporal and spatial multi-scale nature of the material controls its response. As part of the overarching goal of developing computational capabilities to predict the performance of conventional earth-penetrating weapons, this project focuses specifically on developing new models and numerical capabilities for modeling sand response in ALE3D. There is general recognition that granular materials behave in a manner that defies conventional continuum approaches which rely on response locality and which degrade in the presence of strong response nonlinearities, localization, and phase gradients. There are many numerical tools available to address parts of the problem. However, to enhance modeling capability, this project is pursuing a bottom-up approach of building constitutive models from higher fidelity, smaller spatial scale simulations (rather than from macro-scale observations of physical behavior as is traditionally employed) that are being augmented to address the unique challenges of mesoscale modeling of dynamically loaded granular materials. Through understanding response and sensitivity at the grain-scale, it is expected that better reduced order representations of response can be formulated at the continuum scale as illustrated in Figure 1 and Figure 2. The final result of this project is to implement such reduced order models in the ALE3D material library for general use.

Experimental investigation of sand consolidation using high-temperature alkaline solution  

E-Print Network (OSTI)

An experimental study was conducted to better understand the sand consolidation process under high-temperature alkaline solution. Wilmington Tar sand samples were successfully consolidated in the laboratory using high-temperature (250-260?C) solution of sodium carbonate (pH 11-12). The sample was placed in a vertical 18 in. long aluminum cylindrical cell with an ID of 1.5 in.. The top half of the cell was thermally insulated while the bottom half was cooled. Hot alkaline solution was injected at 20 ml/min for 3-4 hours at the top of the cell and liquid produced at the bottom of the cell. After each experiment, the cell contents were removed and analyzed to determine if sand consolidation occurred. Both aggregates of sand grains and sectioned and polished epoxy-mounted sand grains were examined and analyzed using an electron microprobe to determine any change in shape, size, or composition of the sand pack and precipitation and growth of secondary phases. To better understand the process, experiments were subsequently conducted using samples of pure quartz, pure feldspar, and a 50:50 (by weight) mixture of quartz and feldspar. In each case, both varied 20-40 mesh and 50-250 mesh grain size samples were used. For the 20-40 mesh cases, zeolites and a mixture of amorphous silica and sodium carbonate were deposited on grain surfaces but were insufficient to cause overall sand consolidation. However, when a finer, poorly sorted (50-250 mesh) 50:50 mixture of feldspar and quartz was used, sand consolidation was obtained in 2.5 hours. At the top, hotter part of the cell, equant and acicular zeolite crystals (sodium aluminum silicates) weakly bound the sand grains. At the bottom and cooler part of the cell, the sand grains were strongly bound by a mixture of amorphous silica and sodium carbonate. Results to-date indicate that both zeolite and silica may be cementing agents, the grain-bonding strength depending on the grain surface area. This investigation is part of an ongoing research. The temperature, injection rate, and pH of the alkaline solution, treating time and "soaking period" are considered important process parameters that need to be further investigated.

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

SciTech Connect

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

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

SciTech Connect

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

Short rotation Wood Crops Program  

DOE Green Energy (OSTI)

This report synthesizes the technical progress of research projects in the Short Rotation Woody Crops Program for the year ending September 30, 1989. The primary goal of this research program, sponsored by the US Department of Energy's Biofuels and Municipal Waste Technology Division, is the development of a viable technology for producing renewable feedstocks for conversion to biofuels. One of the more significant accomplishments was the documentation that short-rotation woody crops total delivered costs could be $40/Mg or less under optimistic but attainable conditions. By taking advantage of federal subsidies such as those offered under the Conservation Reserve Program, wood energy feedstock costs could be lower. Genetic improvement studies are broadening species performance within geographic regions and under less-than-optimum site conditions. Advances in physiological research are identifying key characteristics of species productivity and response to nutrient applications. Recent developments utilizing biotechnology have achieved success in cell and tissue culture, somaclonal variation, and gene-insertion studies. Productivity gains have been realized with advanced cultural studies of spacing, coppice, and mixed-species trials. 8 figs., 20 tabs.

Laboratory Analysis of a New Sand Consolidation Material for Oilfield Applications  

E-Print Network (OSTI)

The production of sand can be a major issue in many young, unconsolidated sandstone formations where there is little to no cement holding the individual sand grains together. When such reservoirs are produced, quite often operators face problems with reduced well productivity and equipment failure. Because of these issues, the industry has developed numerous techniques in its effort to control formation sand production. Sand consolidation is one technology that has been studied and used since the 1940s. The theory behind sand consolidation technology is to place a liquid material which will create a grain to grain contact that will bind individual sand grains together. Most consolidation treatments contain a preflush to clean and wet the surface, the consolidating system to bind the sand grains and give residual strength, and, finally, an overflush to ensure the formation is still able to produce fluids. With the successful placement of this fluid, the sand grains will be locked in placed so that they will not be produced. The technology has gone through many phases of conception since the 1940s; however, most consolidation material that is pumped in the past has been based upon an epoxy or furan backbone. While there are many technologies available, for the purpose of my research, the epoxy technology was experimentally investigated. The testing of the fluid involved investigating numerous additives to obtain the correct residual strength of the sample, as well as the necessary retained permeability. For the epoxy fluid, the optimal preflush, epoxy system and overflush formulations were determined after 250 checkout tests. Based upon these tests, the fluid was optimized to its working time and UCS results. The optimal system included the addition of PA2 to the preflush, along with PA1 and an aromatic amine curing agent to the epoxy system. PA1 and PA2 are adhesion promoter additives which were deemed necessary as a result of the testing. This system was then tested further in a HP/HT cell. While there is still room for improvement with respect to retained permeability, the system still performs very well in terms of UCS.

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

Science Conference Proceedings (OSTI)

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

Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook April 2003 Overview World Oil Markets. Crude oil prices fell sharply at the onset of war in Iraq, but the initial declines probably overshot levels that we consider to be generally consistent with fundamental factors in the world oil market. Thus, while near-term price averages are likely to be below our previous projections, the baseline outlook for crude oil prices (while generally lower) is not drastically different and includes an average for spot West Texas Intermediate (WTI) that is close to $30 per barrel in 2003 (Figure 1). The mix of uncertainties related to key oil production areas has changed since last month, as Venezuelan production has accelerated beyond previous estimates while Nigerian output has been reduced due to internal conflict.

Production of Natural Gas and Fluid Flow in Tight Sand Reservoirs  

Science Conference Proceedings (OSTI)

This document reports progress of this research effort in identifying relationships and defining dependencies between macroscopic reservoir parameters strongly affected by microscopic flow dynamics and production well performance in tight gas sand reservoirs. These dependencies are investigated by identifying the main transport mechanisms at the pore scale that should affect fluids flow at the reservoir scale. A critical review of commercial reservoir simulators, used to predict tight sand gas reservoir, revealed that many are poor when used to model fluid flow through tight reservoirs. Conventional simulators ignore altogether or model incorrectly certain phenomena such as, Knudsen diffusion, electro-kinetic effects, ordinary diffusion mechanisms and water vaporization. We studied the effect of Knudsen's number in Klinkenberg's equation and evaluated the effect of different flow regimes on Klinkenberg's parameter b. We developed a model capable of explaining the pressure dependence of this parameter that has been experimentally observed, but not explained in the conventional formalisms. We demonstrated the relevance of this, so far ignored effect, in tight sands reservoir modeling. A 2-D numerical simulator based on equations that capture the above mentioned phenomena was developed. Dynamic implications of new equations are comprehensively discussed in our work and their relative contribution to the flow rate is evaluated. We performed several simulation sensitivity studies that evidenced that, in general terms, our formalism should be implemented in order to get more reliable tight sands gas reservoirs' predictions.

Production of Natural Gas and Fluid Flow in Tight Sand Reservoirs  

Science Conference Proceedings (OSTI)

This document reports progress of this research effort in identifying possible relationships and defining dependencies between macroscopic reservoir parameters strongly affected by microscopic flow dynamics and production well performance in tight gas sand reservoirs. Based on a critical review of the available literature, a better understanding of the main weaknesses of the current state of the art of modeling and simulation for tight sand reservoirs has been reached. Progress has been made in the development and implementation of a simple reservoir simulator that is still able to overcome some of the deficiencies detected. The simulator will be used to quantify the impact of microscopic phenomena in the macroscopic behavior of tight sand gas reservoirs. Phenomena such as, Knudsen diffusion, electro-kinetic effects, ordinary diffusion mechanisms and water vaporization are being considered as part of this study. To date, the adequate modeling of gas slippage in porous media has been determined to be of great relevance in order to explain unexpected fluid flow behavior in tight sand reservoirs.

The performance of the small-angle diffractometer, SAND at IPNS.  

Science Conference Proceedings (OSTI)

The time-of-flight small-angle diffractometer SAND has been serving the scientific user community since 1996. One notable feature of SAND is its capability to measure the scattered intensity in a wide Q (4{pi}sin{theta}/{lambda}, where 2{theta} is the scattering angle and {lambda} is the wavelength of the neutrons) range of 0.0035 to 0.5 {angstrom}{sup {minus}1} in a single measurement. The optical alignment system makes it easy to set up the instrument and the sample. The cryogenically cooled MgO filter reduces the fast neutrons over two orders of magnitude, while still transmitting over 70% of the cold neutrons. A drum chopper running at 15 Hz suppresses the delayed neutron background. SAND has a variety of ancillary equipment to control the sample environment. In this paper we describe the features of the SAND instrument, compare its data on a few standard samples with those measured at well established centers in the world, and display two scientific examples which take advantage of measuring data in a wide Q-range in a single measurement. With a new set of tight collimators the Q{sub min} can be lowered to 0.002 {angstrom}{sup {minus}1} and the presently installed high-angle bank of detectors will extend the Q{sub max} to 2 {angstrom}{sup {minus}1}.

Use of Brazilian sugarcane bagasse ash in concrete as sand replacement  

SciTech Connect

Sugarcane today plays a major role in the worldwide economy, and Brazil is the leading producer of sugar and alcohol, which are important international commodities. The production process generates bagasse as a waste, which is used as fuel to stoke boilers that produce steam for electricity cogeneration. The final product of this burning is residual sugarcane bagasse ash (SBA), which is normally used as fertilizer in sugarcane plantations. Ash stands out among agroindustrial wastes because it results from energy generating processes. Many types of ash do not have hydraulic or pozzolanic reactivity, but can be used in civil construction as inert materials. The present study used ash collected from four sugar mills in the region of Sao Carlos, SP, Brazil, which is one of the world's largest producers of sugarcane. The ash samples were subjected to chemical characterization, sieve analysis, determination of specific gravity, X-ray diffraction, scanning electron microscopy, and solubilization and leaching tests. Mortars and concretes with SBA as sand replacement were produced and tests were carried out: compressive strength, tensile strength and elastic modulus. The results indicated that the SBA samples presented physical properties similar to those of natural sand. Several heavy metals were found in the SBA samples, indicating the need to restrict its use as a fertilizer. The mortars produced with SBA in place of sand showed better mechanical results than the reference samples. SBA can be used as a partial substitute of sand in concretes made with cement slag-modified Portland cement.

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

SciTech Connect

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

Occurrence of gas hydrate in Oligocene Frio sand: Alaminos Canyon Block 818: Northern Gulf of Mexico  

SciTech Connect

A unique set of high-quality downhole shallow subsurface well log data combined with industry standard 3D seismic data from the Alaminos Canyon area has enabled the first detailed description of a concentrated gas hydrate accumulation within sand in the Gulf of Mexico. The gas hydrate occurs within very fine grained, immature volcaniclastic sands of the Oligocene Frio sand. Analysis of well data acquired from the Alaminos Canyon Block 818 No.1 ('Tigershark') well shows a total gas hydrate occurrence 13 m thick, with inferred gas hydrate saturation as high as 80% of sediment pore space. Average porosity in the reservoir is estimated from log data at approximately 42%. Permeability in the absence of gas hydrates, as revealed from the analysis of core samples retrieved from the well, ranges from 600 to 1500 millidarcies. The 3-D seismic data reveals a strong reflector consistent with significant increase in acoustic velocities that correlates with the top of the gas-hydrate-bearing sand. This reflector extends across an area of approximately 0.8 km{sup 2} and delineates the minimal probable extent of the gas hydrate accumulation. The base of the inferred gas-hydrate zone also correlates well with a very strong seismic reflector that indicates transition into units of significantly reduced acoustic velocity. Seismic inversion analyses indicate uniformly high gas-hydrate saturations throughout the region where the Frio sand exists within the gas hydrate stability zone. Numerical modeling of the potential production of natural gas from the interpreted accumulation indicates serious challenges for depressurization-based production in settings with strong potential pressure support from extensive underlying aquifers.

X-ray computed-tomography observations of water flow through anisotropic methane hydrate-bearing sand  

SciTech Connect

We used X-ray computed tomography (CT) to image and quantify the effect of a heterogeneous sand grain-size distribution on the formation and dissociation of methane hydrate, as well as the effect on water flow through the heterogeneous hydrate-bearing sand. A 28 cm long sand column was packed with several segments having vertical and horizontal layers with sands of different grain-size distributions. During the hydrate formation, water redistribution occurred. Observations of water flow through the hydrate-bearing sands showed that water was imbibed more readily into the fine sand, and that higher hydrate saturation increased water imbibition in the coarse sand due to increased capillary strength. Hydrate dissociation induced by depressurization resulted in different flow patterns with the different grain sizes and hydrate saturations, but the relationships between dissociation rates and the grain sizes could not be identified using the CT images. The formation, presence, and dissociation of hydrate in the pore space dramatically impact water saturation and flow in the system.

Effective fracture geometry obtained with large water sand ratio  

E-Print Network (OSTI)

Shale gas formation exhibits some unusual reservoir characteristics: nano-darcy matrix permeability, presence of natural fractures and gas storage on the matrix surface that makes it unique in many ways. It’s difficult to design an optimum fracture treatment for such formation and even more difficult is to describe production behavior using a reservoir model. So far homogeneous, two wing fracture, and natural fracture models have been used for this purpose without much success. Micro seismic mapping technique is used to measure the fracture propagation in real time. This measurement in naturally fractured shale formation suggests a growth of fracture network instead of a traditional two wing fractures. There is an industry wise consensus that fracture network plays an important role in determining the well productivity of such formations. A well with high density of fracture networks supposed to have better productivity. Shale formations have also exhibited production pattern which is very different from conventional or tight gas reservoir. Initial flow period is marked by steep decline in production while the late time production exhibits a slow decline. One of the arguments put for this behavior is linear flow from a bi-wing fractured well at early time and contribution of adsorbed gas in production at late time. However, bi-wing fracture geometry is not supported by the micro-seismic observation. A realistic model should include both the fracture network and adsorbed gas property. In this research we have proposed a new Power Law Permability model to simulate fluid flow from hydraulically fractured Shale formation. This model was first described by Valko & Fnu (2002) and used for analyzing acid treatment jobs. The key idea of this model is to use a power law permeability function that varies with the radial distance from well bore. Scaling exponent of this power law function has been named power law index. The permeability function has also been termed as secondary permeability. This work introduces the method of Laplace solution to solve the problem of transient and pseudo steady-state flow in a fracture network. Development and validation of this method and its extension to predict the pressure (and production) behaviour of fracture network were made using a novel technic. Pressure solution was then combined with material balance through productivity index to make production forecast. Reservoir rock volume affected by the fracture stimulation treatment that contributes in the production is called effective stimulated volume. This represents the extent of fracture network in this case. Barnett shale formation is a naturally fractured shale reservoir in Fort Worth basin. Several production wells from this formation was analysed using Power Law Model and it was found that wells productivity are highly dependent on stimulated volume. Apparently the wells flow under pseudo steady state for most part of their producing life and the effect of boundary on production is evident in as soon as one months of production. Due to short period of transient flow production from Barnett formations is expected to be largely independent of the relative distribution of permeability and highly dependent on the stimulated area and induced secondary permeability. However, an indirect relationship between permeability distribution and production rate is observed. A well with low power law index shows a better (more even) secondary permeability distribution in spatial direction, larger stimulated volume and better production. A comparative analysis between the new model and traditional fracture model was made. It was found that both models can be used successfully for history matching and production forecasting from hydraulically fractured shale gas formation.

Polymer flotation and activated carbon adsorption treatment for in situ tar sand process water  

SciTech Connect

Tar sand deposits in the United States are estimated to exceed thirty billion barrels, and offer long term potential for satisfying future energy needs. At present there is no commercial scale tar sand extraction industry in the United States, although several bench and pilot scale research projects have been completed. Three of the larger field scale experiments were completed by the Department of Energy (DOE) at a site near Vernal, Utah. The first two of these efforts involved in situ combustion while the third used steam drive. This paper reviews some of the flotation configurations which were used to generate a large (350 L) volume of treated effluent as well as describing some toxicology and analytical chemistry protocols used to characterize these fluids. Additional emphasis is placed upon a series of activated carbon adsorption experiments undertaken to detoxify the flotation effluents.

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

SciTech Connect

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

Improvements in Sand Mold/Core Technology: Effects on Casting Finish  

SciTech Connect

In this study, the development and impact of density gradients on metal castings were investigated using sand molds/cores from both industry and from in-house production. In spite of the size of the castings market, almost no quantitative information about density variation within the molds/cores themselves is available. In particular, a predictive understanding of how structure and binder content/chemistry/mixing contribute to the final surface finish of these products does not exist. In this program we attempted to bridge this gap by working directly with domestic companies in examining the issues of surface finish and thermal reclamation costs resulting from the use of sand molds/cores. We show that these can be substantially reduced by the development of an in-depth understanding of density variations that correlate to surface finish. Our experimental tools and our experience with them made us uniquely qualified to achieve technical progress.

Some Geotechnical Properties of Palm Biodiesel Contaminated Mining Sand and Weathered Granite Soil  

E-Print Network (OSTI)

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

Numerical simulation of transient gas flow during underbalanced drilling into a gas sand  

Science Conference Proceedings (OSTI)

Shallow gas drilling has long been recognized as a serious problem in offshore operations. Low fracture gradients and shallow casing do not permit shutting- in the well. Computer simulations of gas kicks during drilling require accurate description of the gas flow rate from the formation into the wellbore. The problem is complicated by the fact that during drilling into a gas sand the effective wellbore area exposed to flow is continually changing until the formation has been completely drilled. This paper describes a numerical model developed to calculate gas flow into the wellbore while drilling underbalanced into a gas sand. A two-dimensional finite difference model of transient flow from the reservoir has been coupled with a one-dimensional finite element model of two-phase flow in the wellbore.

Application of gas flotation and foam separation for the treatment of tar-sand wastewaters  

SciTech Connect

A feasibility study was undertaken to evaluate the potential of air flotation and foam separation for the treatment of tar sand, steam generation waste waters collected following an in-situ experiment in Vernal, Utah. It was found that the process waters were not amenable to treatment by means of polymer-aided air flotation or foam separation. Suspended solids were readily removed by the process, but dissolved organic substances were not affected significantly.

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

SciTech Connect

A laboratory investigation was made of the effects of temperature on wave velocities in well cemented Massillon and Boise sandstones and unconsolidated Ottawa sand saturated with heavy hydrocarbons, as well as the dependence of compressional velocities in the hydrocarbons themselves as a function of temperature. The hydrocarbons selected as pore saturants were a commercial paraffin wax, 1-Eicosene, natural heavy crude, and natural tar. The experimental results show that the compressional wave velocities in the hydrocarbons decrease markedly with increasing temperature. In contrast wave velocities in the Massillon and Boise sandstones and unconsolidated Ottawa sand saturated with air or water decrease only little with increasing temperatures. The main reason for the large decreases in rocks with hydrocarbons is the melting of solid hydrocarbons, and high pore pressure. Thermal expansion of the saturants, and possibly thermal cracking of the heavy fractions and vaporization of the light fractions of the hydrocarbons may also contribute. The large decreases of the compressional and shear wave velocities in the hydrocarbon-saturated rocks and sands with temperature, suggest that seismic measurements such as used in seismology or borehole tomography may be very useful in detecting steam fronts in heavy hydrocarbon reservoirs undergoing steam flooding.

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

Science Conference Proceedings (OSTI)

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

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

SciTech Connect

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

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.

Western Gas Sands Subprogram. Status report, October-November-December 1982  

Science Conference Proceedings (OSTI)

The progress during October, November and December 1982 of government-sponsored projects to increase gas production from low permeability gas sands of the Western United States, is summarized in this edition of the Western Gas Sands Subprogram (WGSS) Quarterly Status Report. During the quarter, major changes were made in the management of the subprogram. Personnel in the Division of Petroleum Projects Management at the Morgantown Energy Technology Center (METC) assumed the role of management for the Western Gas Sands Subprogram that had been performed by the Bartlesville Energy Technology Center (BETC). BETC continued in-house research on the fluid and proppant problems of fracture conductivity, and management of the Multi-Well Experiment (MWX). Owing to economic constraints, all efforts at the Sandia National Laboratory that were not directly related to the performance of MWX were terminated. The projects at the Lawrence Livermore National Laboratory and the Los Alamos National Laboratory were reduced by approximately 50 percent. The efforts at the USGS were reduced by 70 percent. Significant progress was made in the MWX project. Both the Upper and Lower Cozzette zones were production tested. Interference tests run on the Upper Cozzette showed much higher in situ permeability than core and log analysis indicated. This higher permeability has been attributed to the natural fractures. The site was closed for the winter on December 22 and the test trailer moved to CER Corporation, Las Vegas, for maintenance and upgrading. 40 figures, 16 tables.

Pyrolysis of Sunnyside (Utah) tar sand: Characterization of volatile compound evolution  

DOE Green Energy (OSTI)

Sunnyside (Utah) tar sand was subjected to programmed temperature pyrolysis and the volatile products were detected by tandem on-line mass spectrometry (MS/MS) in real time analyses. A heating rate of 4/degree/C/min from room temperature to 900/degree/C was employed. Evolution of hydrogen, light hydrocarbons, nitrogen-, sulfur- and oxygen-containing compounds was monitored by MS or MS/MS detection. Evolution of volatile organic compounds occurred in two regimes: 1) low temperature (maximum evolution at 150 to 175/degree C), corresponding to entrained organics, and 2) high temperature (maximum evolution at 440 to 460/degreeC), corresponding to cracking of large organic components. Pyrolysis yields were dominated by the evolution of light hydrocarbons. Alkanes and alkenes of two carbons and higher had temperatures of maximum evolution at approximately 440/degree/C, and methane at approximately 474/degree/C. Aromatic hydrocarbons had temperatures of maximum evolution slightly higher, at approximately 450/degree/C. In general, H/sub2/, CO, and CO/sub2/ exhibited evolution associated with hydrocarbon cracking reactions, and high temperature evolution associated with mineral decomposition, the water-gas shift reaction, and gasification reactions. Compared to other domestic tar sands, the gas evolution relected more mineral decomposition character for Sunnyside tar sand. 26 refs., 6 figs., 3 tabs.

Improving both bond strength and corrosion resistance of steel rebar in concrete by water immersion or sand blasting of rebar  

Science Conference Proceedings (OSTI)

Water immersion (2 days) and sand blasting were similarly effective for treating steel rebars for the purpose of improvement steel-concrete bond strength and corrosion resistance of steel in concrete. The increase in bond strength is due to surface roughening in the case of sand blasting and the presence of a surface layer in the case of water immersion. The increase in corrosion resistance is due to the surface uniformity rendered by either treatment.

Short-Distance Structure of Nuclei  

Science Conference Proceedings (OSTI)

One of Jefferson Lab's original missions was to further our understanding of the short-distance structure of nuclei. In particular, to understand what happens when two or more nucleons within a nucleus have strongly overlapping wave-functions; a phenomena commonly referred to as short-range correlations. Herein, we review the results of the (e,e'), (e,e'p) and (e,e'pN) reactions that have been used at Jefferson Lab to probe this short-distance structure as well as provide an outlook for future experiments.

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

Science Conference Proceedings (OSTI)

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

Seismic amplitude and coherency response of channel sand, offshore Louisiana, Gulf of Mexico  

E-Print Network (OSTI)

Geological drilling hazards are a major concern in the ics. drilling and development of offshore reservoirs. Some of these hazards may display high amplitudes on seismic profiles and some may be associated with stratigraphic features. Seismic amplitude anomalies associated with channel sand deposits may indicate potential accumulations of hydrocarbons in reservoirs. However, shallow hydrocarbon accumulations are rarely of production size. More often, they are potential geological drilling hazards that could inhibit the development of petroleum resources from deeper hydrocarbon-bearing layers. Traditionally, existing and potential geologic hazards are identified by interpretation of high-resolution site survey data, acquired specifically for drilling hazard delineation. This paper describes a new technique for drilling hazard identification using a conventional 3D seismic amplitude dataset. An event coherence calculation program is applied to a 3D seismic dataset to derive seismic attributes sufficient to highlight structural and stratigraphic discontinuities in the area. A resultant 3D difference cube is used to establish fault framework and to detect spatial distribution of channel deposits in the area and their geometries. Superposition of the difference cube on seismic amplitude data allows simultaneous display of structural and stratigraphic discontinuities and reflectivity information. Therefore, it is used for the delineation of channels, which show anomalous amplitudes, identification of their dimensions and spatial locations, and implication of gas-charged sand distribution within the detected channel. The paper gives a detailed description of a workflow, which was found sufficient for delineation of likely gas-charged sand channels, and discusses the ways to adjust the proposed workbox to specific objectives.

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

E-Print Network (OSTI)

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

Short-term energy outlook: Quarterly projections  

SciTech Connect

The Energy Information Administration (EIA) quarterly forecasts of short-term energy supply, demand, and prices are revised in January, April, July, and October for publication in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes previous forecast errors, compares recent projections by other forecasters, and discusses current topics of the short-term energy markets (see Short- Term Energy Outlook: Annual Supplement, DOE/EIA-0202). The principal users of the Outlook are managers and energy analysts in private industry and government. The projections in this volume extend through the fourth quarter of 1990. The forecasts are produced using the Short-term Integrated Forecasting System (STIFS). The STIFS model uses two principal driving variables: a macroeconomic forecast and world oil price assumptions. Macroeconomic forecasts produced by data Resources, Inc., (DRI), are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic forecast. EIA's Oil Market Simulation Model is used to project world oil prices. 20 refs., 17 figs., 16 tabs.

Means for limiting and ameliorating electrode shorting  

SciTech Connect

A fuse and filter arrangement is described for limiting and ameliorating electrode shorting in capacitive deionization water purification systems utilizing carbon aerogel, for example. This arrangement limits and ameliorates the effects of conducting particles or debonded carbon aerogel in shorting the electrodes of a system such as a capacitive deionization water purification system. This is important because of the small interelectrode spacing and the finite possibility of debonding or fragmentation of carbon aerogel in a large system. The fuse and filter arrangement electrically protect the entire system from shutting down if a single pair of electrodes is shorted and mechanically prevents a conducting particle from migrating through the electrode stack, shorting a series of electrode pairs in sequence. It also limits the amount of energy released in a shorting event. The arrangement consists of a set of circuit breakers or fuses with one fuse or breaker in the power line connected to one electrode of each electrode pair and a set of screens of filters in the water flow channels between each set of electrode pairs.

Short Gamma-Ray Bursts Are Different  

E-Print Network (OSTI)

We analyze BATSE time-tagged event (TTE) data for short gamma-ray bursts (T90 duration burst. Performing the cross-correlation between two energy bands, we measure an average lag ~ 20-40 x shorter than for long bursts, and a lag distribution close to symmetric about zero - unlike long bursts. Using a "Bayesian Block" method to identify significantly distinct pulse peaks, we find an order of magnitude fewer pulses than found in studies of long bursts. The disparity in lag magnitude is discontinuous across the ~ 2-s valley between long and short bursts. Thus, short bursts do not appear to be representable as a continuation of long bursts' temporal characteristics.

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

SciTech Connect

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

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

SciTech Connect

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

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

E-Print Network (OSTI)

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

Flowsheet modifications for dissolution of sand, slag, and crucible residues in the F-canyon dissolvers  

Science Conference Proceedings (OSTI)

An initial flowsheet for the dissolution of sand, slag, and crucible (SS{ampersand}C) was developed for the F- Canyon dissolvers as an alternative to dissolution in FB-Line. In that flowsheet, the sand fines were separated from the slag chunks and crucible fragments. Those two SS{ampersand}C streams were packaged separately in mild-steel cans for dissolution in the 6.4D dissolver. Nuclear safety constraints limited the dissolver charge to approximately 350 grams of plutonium in two of the three wells of the dissolver insert and required 0.23M (molar) boron as a soluble neutron poison in the 9.3M nitric acid/0.013M fluoride dissolver solution. During the first dissolution of SS{ampersand}C fines, it became apparent that a significant amount of the plutonium charged to the 6.4D dissolver did not dissolve in the time predicted by previous laboratory experiments. The extended dissolution time was attributed to fluoride complexation by boron. An extensive research and development (R{ampersand}D) program was initiated to investigate the dissolution chemistry and the physical configuration of the dissolver insert to understand what flowsheet modifications were needed to achieve a viable dissolution process.

Mineral Dissolution and Secondary Precipitation on Quartz Sand in Simulated Hanford Tank Solutions Affecting Subsurface Porosity  

SciTech Connect

Highly alkaline nuclear waste solutions have been released from underground nuclear waste storage tanks and pipelines into the vadose zone at the U.S. Department of Energy’s Hanford Site in Washington, causing mineral dissolution and re-precipitation upon contact with subsurface sediments. High pH caustic NaNO3 solutions with and without dissolved Al were reacted with quartz sand through flow-through columns stepwise at 45, 51, and 89°C to simulate possible reactions between leaked nuclear waste solution and primary subsurface mineral. Upon reaction, Si was released from the dissolution of quartz sand, and nitrate-cancrinite [Na8Si6Al6O24(NO3)2] precipitated on the quartz surface as a secondary mineral phase. Both steady-state dissolution and precipitation kinetics were quantified, and quartz dissolution apparent activation energy was determined. Mineral alteration through dissolution and precipitation processes results in pore volume and structure changes in the subsurface porous media. In this study, the column porosity increased up to 40.3% in the pure dissolution column when no dissolved Al was present in the leachate, whereas up to a 26.5% porosity decrease was found in columns where both dissolution and precipitation were observed because of the presence of Al in the input solution. The porosity change was also confirmed by calculation using the dissolution and precipitation rates and mineral volume changes.

Short-term energy outlook. Quarterly projections  

SciTech Connect

Energy Information Administration (EIA) quarterly forecasts of short-term energy supply, demand, and prices are revised in February, May, August, and November for publication in the Short-Term Energy Outlook, quarterly projections. Methodology volumes, which are published with the May and November issues, contain descriptions of the forecasting system and detailed analyses of the current issues that affect EIA's short-term energy forecasts. The forecasts are produced using the Short-Term Integrated Forecasting System (STIFS). Two principal driving variables are used in the STIFS model: the macroeconomic forecast and the world oil price assumptions. The macroeconomic forecasts, which are produced by Data Resources, Inc., (DRI), are adjusted by EIA in cases where EIA projections of the world price of crude oil differ from DRI estimates. EIA's Oil Market Simulation Model is used to project the world oil prices. The three projections for petroleum supply and demand are based on low, medium, and high economic growth scenarios which incorporate high, medium, and low crude oil price trajectories. In general, the following discussion of the forecast refers to the medium, or base case, scenario. Total petroleum consumption sensitivities, using varying assumptions about the level of price, weather, and economic activity are tabulated.

HETEROGENEITY IN SHORT GAMMA-RAY BURSTS  

SciTech Connect

We analyze the Swift/BAT sample of short gamma-ray bursts, using an objective Bayesian Block procedure to extract temporal descriptors of the bursts' initial pulse complexes (IPCs). The sample is comprised of 12 and 41 bursts with and without extended emission (EE) components, respectively. IPCs of non-EE bursts are dominated by single pulse structures, while EE bursts tend to have two or more pulse structures. The medians of characteristic timescales-durations, pulse structure widths, and peak intervals-for EE bursts are factors of {approx}2-3 longer than for non-EE bursts. A trend previously reported by Hakkila and colleagues unifying long and short bursts-the anti-correlation of pulse intensity and width-continues in the two short burst groups, with non-EE bursts extending to more intense, narrower pulses. In addition, we find that preceding and succeeding pulse intensities are anti-correlated with pulse interval. We also examine the short burst X-ray afterglows as observed by the Swift/X-Ray Telescope (XRT). The median flux of the initial XRT detections for EE bursts ({approx}6x10{sup -10} erg cm{sup -2} s{sup -1}) is {approx}>20x brighter than for non-EE bursts, and the median X-ray afterglow duration for EE bursts ({approx}60,000 s) is {approx}30x longer than for non-EE bursts. The tendency for EE bursts toward longer prompt-emission timescales and higher initial X-ray afterglow fluxes implies larger energy injections powering the afterglows. The longer-lasting X-ray afterglows of EE bursts may suggest that a significant fraction explode into denser environments than non-EE bursts, or that the sometimes-dominant EE component efficiently powers the afterglow. Combined, these results favor different progenitors for EE and non-EE short bursts.

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

E-Print Network (OSTI)

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

Pore-scale mechanisms of gas flow in tight sand reservoirs  

Science Conference Proceedings (OSTI)

Tight gas sands are unconventional hydrocarbon energy resource storing large volume of natural gas. Microscopy and 3D imaging of reservoir samples at different scales and resolutions provide insights into the coaredo not significantly smaller in size than conventional sandstones, the extremely dense grain packing makes the pore space tortuous, and the porosity is small. In some cases the inter-granular void space is presented by micron-scale slits, whose geometry requires imaging at submicron resolutions. Maximal Inscribed Spheres computations simulate different scenarios of capillary-equilibrium two-phase fluid displacement. For tight sands, the simulations predict an unusually low wetting fluid saturation threshold, at which the non-wetting phase becomes disconnected. Flow simulations in combination with Maximal Inscribed Spheres computations evaluate relative permeability curves. The computations show that at the threshold saturation, when the nonwetting fluid becomes disconnected, the flow of both fluids is practically blocked. The nonwetting phase is immobile due to the disconnectedness, while the permeability to the wetting phase remains essentially equal to zero due to the pore space geometry. This observation explains the Permeability Jail, which was defined earlier by others. The gas is trapped by capillarity, and the brine is immobile due to the dynamic effects. At the same time, in drainage, simulations predict that the mobility of at least one of the fluids is greater than zero at all saturations. A pore-scale model of gas condensate dropout predicts the rate to be proportional to the scalar product of the fluid velocity and pressure gradient. The narrowest constriction in the flow path is subject to the highest rate of condensation. The pore-scale model naturally upscales to the Panfilov's Darcy-scale model, which implies that the condensate dropout rate is proportional to the pressure gradient squared. Pressure gradient is the greatest near the matrix-fracture interface. The distinctive two-phase flow properties of tight sand imply that a small amount of gas condensate can seriously affect the recovery rate by blocking gas flow. Dry gas injection, pressure maintenance, or heating can help to preserve the mobility of gas phase. A small amount of water can increase the mobility of gas condensate.

Method and apparatus for amplification of a laser pulse in a free electron laser amplifier where the laser pulse duration may be a small fraction of the electron beam pulse duration used for amplification. An electron beam pulse is passed through a first wiggler magnet and a short laser pulse to be amplified is passed through the same wiggler so that only the energy of the last fraction, f, (f<1) of the electron beam pulse is consumed in amplifying the laser pulse. After suitable delay of the electron beam, the process is repeated in a second wiggler magnet, a third, . . . , where substantially the same fraction f of the remainder of the electron beam pulse is consumed in amplification of the given short laser pulse in each wiggler magnet region until the useful electron beam energy is substantially completely consumed by amplification of the laser pulse.

Transient nanobubbles in short-time electrolysis  

E-Print Network (OSTI)

Water electrolysis in a microsystem is observed and analyzed on a short-time scale ~10 us. Very unusual properties of the process are stressed. An extremely high current density is observed because the process is not limited by the diffusion of electroactive species. The high current is accompanied by a high relative supersaturation S>1000 that results in homogeneous nucleation of bubbles. On the short-time scale only nanobubbles can be formed. These nanobubbles densely cover the electrodes and aggregate at a later time to microbubbles. The effect is significantly intensified with a small increase of temperature. Application of alternating polarity voltage pulses produces bubbles containing a mixture of hydrogen and oxygen. Spontaneous reaction between gases is observed for stoichiometric bubbles with the size smallaer than 150 nm. Such bubbles disintegrate violently affecting the surface of electrodes.

Why Do Emerging Economies Borrow Short Term?  

E-Print Network (OSTI)

We argue that emerging economies borrow short term due to the high risk premium charged by international capital markets on long-term debt. First, we present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders. By issuing long-term debt, the government lowers the probability of a liquidity crisis, transferring risk to bondholders. In equilibrium, this risk is reflected in a higher risk premium and borrowing cost. Therefore, the government faces a trade-off between safer long-term borrowing and cheaper short-term debt. Second, we construct a new database of sovereign bond prices and issuance. We show that emerging economies pay a positive term premium (a higher risk premium on long-term bonds than on short-term bonds). During crises, the term premium increases, with issuance shifting toward shorter maturities. This suggests that changes in bondholders ’ risk aversion are important to understand emerging market crises.

Temperature effects on oil-water relative permeabilities for unconsolidated sands  

SciTech Connect

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

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...

Groundwater flow near the Shoal Site, Sand Springs Range, Nevada: Impact of density-driven flow  

Science Conference Proceedings (OSTI)

The nature of flow from a highland recharge area in a mountain range in north-central Nevada to discharge areas on either side of the range is evaluated to refine a conceptual model of contaminant transport from an underground nuclear test conducted beneath the range. The test, known as the Shoal event, was conducted in 1963 in granitic rocks of the Sand Springs Range. Sparse hydraulic head measurements from the early 1960s suggest flow from the shot location to the east to Fairview Valley, while hydrochemistry supports flow to salt pans in Fourmile Flat to the west. Chemical and isotopic data collected from water samples and during well-logging arc best explained by a reflux brine system on the west side of the Sand Springs Range, rather than a typical local flow system where all flow occurs from recharge areas in the highlands to a central discharge area in a playa. Instead, dense saline water from the playa is apparently being driven toward the range by density contrasts. The data collected between the range and Fourmile Flat suggest the groundwater is a mixture of younger, fresher recharge water with older brine. Chemical contrasts between groundwater in the east and west valleys reflect the absence of re-flux water in Fairview Valley because the regional discharge area is distant and thus there is no accumulation of salts. The refluxing hydraulic system probably developed after the end of the last pluvial period and differences between the location of the groundwater divide based on hydraulic and chemical indicators could reflect movement of the divide as the groundwater system adjusts to the new reflux condition.

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

Science Conference Proceedings (OSTI)

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

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

SciTech Connect

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

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

SciTech Connect

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

Short wavelength ion temperature gradient turbulence  

Science Conference Proceedings (OSTI)

The ion temperature gradient (ITG) mode in the high wavenumber regime (k{sub y}{rho}{sub s}>1), referred to as short wavelength ion temperature gradient mode (SWITG) is studied using the nonlinear gyrokinetic electromagnetic code GENE. It is shown that, although the SWITG mode may be linearly more unstable than the standard long wavelength (k{sub y}{rho}{sub s}<1) ITG mode, nonlinearly its contribution to the total thermal ion heat transport is found to be low. We interpret this as resulting from an increased zonal flow shearing effect on the SWITG mode suppression.

Thomson scattering in short pulse laser experiments  

SciTech Connect

Thomson scattering is well used as a diagnostic in many areas of high energy density physics. In this paper, we quantitatively demonstrate the practicality of using Thomson scattering as a diagnostic of short-pulse laser-plasma experiments in the regime, where the plasmas probed are at solid density and have temperatures of many hundreds of eV using a backlighter produced with an optical laser. This method allows a diagnosis both spatially and temporally of the density and temperature distributions in high energy density laser-plasma interactions which is independent from, and would act as a useful complement to, the existing spectroscopic methods.

Evaluation of water production in tight gas sands in the Cotton Valley formation in the Caspiana, Elm Grove and Frierson fields  

E-Print Network (OSTI)

Normally in tight gas sands, water production is not a problem but in such low permeability reservoirs it is difficult to produce gas at commercial flow rates. Since water is more viscous than gas, very little water is normally produced in low permeability reservoirs. The production of large volumes of water from tight gas sands, say 50-100 bbls of water per MMcf of gas constitutes a cause for concern. High water production (>200 bbls of water per MMcf of gas) has been observed in the low permeability Cotton Valley sands in the Caspiana, Elm Grove and Frierson fields of North Louisiana. This research evaluates water production in the above tight gas sands using field data provided by Matador Resource, a member of the Crisman Institute in Texas A&M university. The research is aimed at providing realistic reservoir scenarios of excess water production in tight gas sands. Log analysis, property trends and well production profiles have been used in establishing the different scenarios. The reservoir simulation results and the production trends show a possible water source from faults and fractures connecting the Travis Peak/Smackover sands to the Cotton Valley sands. An improved understanding of the reservoir would help in further field development.

Facies and architecture of deep-water Sandstone lobes: Comparison of a shale-rich and a sand-rich system  

SciTech Connect

Two different foreland-basin deep-water sandstone systems have been studied for reservoir characterization purposes: the Broto lobes of the Eocene Hecho group, spain, and two sand bodies of the Oligocene-Miocene Arakintos Sandstone, Greece. The shale-rich Broto lobes are characterized by distinct vertical developments in terms of facies and expression of heterogeneity. Bed-thickness trends, lateral extent of sand beds, and facies variability are related to overall sand/shale ratio. A feature common to most of the sandstone packages is the occurrence of a basal slump and/or pebbly mudstone. The dominant sediment source is considered fluvial. Variation in sand quality within and between lobes is high. Deposition is considered to be strongly controlled by tectonics. The sand-rich Arakintos Sandstone consists of massive and pebbly sandstones, forming thick, sandy sheets alternating with relatively coarse-grained, thin-bedded turbidites. Facies, geometries, vertical organization, and the relation between grain size and bed thickness indicate a constrained development of the lobes, partly influenced by preexisting topography. A coastal sediment source is inferred. Little variation exists in sand quality within and between the lobes. The overall regularity in terms of facies, and the absence of slumps, suggest that fluctuations in relative sea level may have formed a major control on deposition. The two lobe systems illustrate the effect of tectonics, sediment type, topographic confinement, and possible sea level on facies and sand body architecture of deep-water sandstone lobes.

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

E-Print Network (OSTI)

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

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

SciTech Connect

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

OPEC members also sought tighter compliance with quotas, calling for production cuts of 2 million barrels per day from April levels. We expect these measures to result in an average total OPEC (including Iraq) crude oil production rate of about 26.7 million barrels per day in the second and third quarters. This production level is not significantly different from our base case assumptions in last month's report. Individual OPEC country shares of these output levels will depend upon the speed with which

October 2002 October 2002 1 Short-Term Energy Outlook October 2002 Overview World Oil Markets: Continued high oil prices are the result of declining OECD commercial oil inventories, worries over a potential clash with Iraq, and OPEC's decision to leave production quotas unchanged at its September meeting. Solid growth in world oil demand this winter (and for 2003 as a whole) is likely to tighten world oil markets and reduce commercial oil inventories.

3 3 1 Short-Term Energy Outlook February 2003 Overview World Oil Markets. World oil markets will likely remain tight through most of 2003, as petroleum inventories and global spare production capacity continue to dwindle amid blasts of cold weather and constrained output from Venezuela. OPEC efforts to increase output to make up for lower Venezuela output has reduced global spare production capacity to only 2 million barrels per day, leaving little room to make up for unexpected supply or demand surprises. Meanwhile, the average West Texas Intermediate (WTI) crude oil price increased by $3.50 to $33 per barrel from December to January (Figure 1). For the year 2003, WTI oil prices are expected to remain over $30 per barrel, even though Venezuelan output appears to be moving toward normal sooner than expected. Also,

November 2002 November 2002 1 Short-Term Energy Outlook November 2002 Overview World Oil Markets: During the past 3-4 months, OPEC 10 production has risen more quickly than projected, thus reducing upward pressure on prices. More specifically, while the West Texas Intermediate (WTI) crude oil spot price averaged $28.84 in October, about $6.70 per barrel above the year-ago level (Figure 1), the WTI average price for fourth quarter 2002 is now projected to soften to $28.20, which is about $2 per barrel below our fourth-quarter projection from last month. Meanwhile, OECD inventory levels, which are now approaching 5 -year lows, should begin to rise over the next few months as additional supplies reach markets, and return to the middle of their observed range by spring.

responders anticipated that energy will comprise 25% or less of the utilization of single-stem short-rotation woody crops between now and 2010. The only exception was a response from California where a substantial biomass energy market does currently exist. Willows (Salix species) are only being developed for energy and only in one part of the United States at present. Responses from herbaceous crop researchers suggested frustration that markets (including biomass energy markets) do not currently exist for the crop, and it was the perception of many that federal incentives will be needed to create such markets. In all crops, responses indicate that a wide variety of research and development activities are needed to enhance the yields and profitability of the crops. Ongoing research activities funded by the U.S. Department of Energy?s Bioenergy Feedstock Development Program are described in an appendix to the paper.

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

SciTech Connect

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

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

DOE Green Energy (OSTI)

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

Impact of early diagenesis of Eolian reservoirs, Great Sand Dunes National Monument, Colorado  

SciTech Connect

Dune and associated alluvial and playa deposits at Great Sand Dunes National Monument, Colorado, provide an excellent opportunity to study early diagenetic development of vertical and horizontal permeability barriers in recent eolian deposits (> 10 ka). Cements observed include calcite, aragonite, protodolomite(.), amorphous silica, iron hydroxide, smectite, trona, and halite. Cementation is controlled by the availability of water, with several hydrologic subenvironments producing different cements. Evaporative cementation in dunes adjacent to playas is commonly dominated by trona and halite, but calcite, aragonite, and amorphous silica also bind the sediment. These cements are generally most concentrated in fine laminations where capillary action has pulled water into dunes. Iron hydroxides, calcite, and amorphous silica precipitate at the interface between ground water and streams or lakes, where the pH gradient may exceed 5 pH units (pH 5.7-11.5). Subsequent movement of the ground-water table can result in cross-cutting cement zones. Early cementation in dunes prevents deflation and provides a mechanism for preservation of the reservoir unit. Intense cementation may permanently occlude porosity, or leaching may reestablish well-interconnected porosity. An understanding of the extent and composition of early cement zones can be used to improve hydrodynamic models for production and enhanced recovery.

Size exclusion chromatography-inductively coupled plasma atomic emission spectrographic study of Fe in bitumens derived from tar sands  

SciTech Connect

This paper reports on bitumens extracted from tar sands from various locations (Utah, California, Kentucky, and Alberta) that were examined by size exclusion chromatography with on-line element-specific detection to study the Fe concentration as a function of size. In most cases, the resulting profiles exhibit unimodal distributions at relatively large molecular size with very similar times for maximum elution. specifically, Sunnyside (Utah) and McKittrick (California) tar-sand bitumens exhibited very intense maxima consistent with extremely high bulk Fe contents. Arroyo Grande (California) exhibited an additional maximum at very large molecular size. This size behavior of the Fe appears to correlate with the large molecular size Ni and V components eluted under the same conditions.

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

Science Conference Proceedings (OSTI)

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

Studies of the terrestrial O{sub 2} and carbon cycles in sand dune gases and in biosphere 2  

Science Conference Proceedings (OSTI)

Molecular oxygen in the atmosphere is coupled tightly to the terrestrial carbon cycle by the processes of photosynthesis, respiration, and burning. This dissertation examines different aspects of this coupling in four chapters. Chapter 1 explores the feasibility of using air from sand dunes to reconstruct atmospheric O{sub 2} composition centuries ago. Such a record would reveal changes in the mass of the terrestrial biosphere, after correction for known fossil fuel combustion, and constrain the fate of anthropogenic CO{sub 2}.

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

SciTech Connect

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

Feasibility of calculating petrophysical properties in tight-sand reservoirs using neural networks. Final report, October 1989-July 1991  

Science Conference Proceedings (OSTI)

The objective of the research was to determine the feasibility of using neural networks to estimate petrophysical properties in tight sand reservoirs. A second objective was to gain some experience concerning how to approach the development of a future prototype, including what should be done and what should be avoided. Gas Research Institute (GRI) focused the project on tight sands because they contain enormous gas reserves and their complicated lithology represents a challenge to log analysts. The data were supplied by GRI from two of its geographically proximate experimental wells in tight sand formations. The nets were tested in sections of those wells that were not used for training, and in two other wells, one in a geographically close but geologically unrelated formation and one in Wyoming. The feasibility testing demonstrated that the relatively simple neural networks developed have comparable accuracy with standard logging analysis estimates in wells that contributed data to the training set. Transportability of the network was tested by using core measurements in two wells in which the nets were not trained, with inconclusive results. Recommendations were made to increase the accuracy of the neural networks.

Continuity and permeability development in the tight gas sands of the eastern Uinta Basin, Utah. Final report  

SciTech Connect

The relationships between reservoir characteristics and flow regimes exhibited by twenty-one Uinta Basin gas wells represent fluvial, lake margin, and lacustrine deposits. Production data were analyzed to determine the type of flow for each well. This analysis indicated that one well exhibits radial flow, thirteen wells linear flow, and seven wells indeterminate flow regimes. Values of SSP, ..delta..t, R/sub w/ and SP curve patterns were determined from well logs. These data were compared for the three types of flow observed. It appears that SSP, R/sub w/ and SP pattern may be useful in qualitatively distinguishing between sands of low continuity and those with moderate continuity. The permeabilities are considerably higher than those normally attributed to ''tight sands.'' Also permeability correlates inversely with the number of sands completed in each well. Consideration of the orientations of linear features in the area and those of reservoir lenses in outcrops indicates that the relationship between frac orientation and lens geometry cannot be effectively predicted without a good technique to predict lens orientation. Completion strategies to optimize frac efficiency are suggested, based upon the findings of this study.

Characterization of Black Trona Waters and use of the waters for recovery of bitumen from US tar sands  

Science Conference Proceedings (OSTI)

There were two principal research objectives for this project. The first objective was to characterize organic material in Black Trona Water with an emphasis on colloids and organic acids. The second objective was to determine the utility of Black Trona Water as a solvent for extracting fossil fuels from US Tar Sands. Spectroscopic studies, molecular weights and shapes of polymeric acids and behavior as a polysoap were determined. Experiments indicate that trona water is preferable to Black Trona Water as an extraction agent for tar sands. The trona water is fairly efficient at stripping bitumen from the sand with gentle heating. In trona water, the displaced bitumen is readily collected on a Teflon surface (i.e., a non-water-wetted surface) with little material dissolving in the water. In contrast, the polysoap in Black Trona Water appears to take up displaced bitumen in a detergent-like process. Separating bitumen from the polysoap would undoubtedly be very difficult. 38 references, 16 figures, 2 tables.

Permeability of laboratory-formed methane-hydrate-bearing sand: Measurements and observations using x-ray computed tomography  

SciTech Connect

Methane hydrate was formed in two moist sands and a sand/silt mixture under a confining stress in an X-ray-transparent pressure vessel. Three initial water saturations were used to form three different methane-hydrate saturations in each medium. X-ray computed tomography (CT) was used to observe location-specific density changes caused by hydrate formation and flowing water. Gas-permeability measurements in each test for the dry, moist, frozen, and hydrate-bearing states are presented. As expected, the effective permeabilities (intrinsic permeability of the medium multiplied by the relative permeability) of the moist sands decreased with increasing moisture content. In a series of tests on a single sample, the effective permeability typically decreased as the pore space became more filled, in the order of dry, moist, frozen, and hydrate-bearing. In each test, water was flowed through the hydrate-bearing medium and we observed the location-specific changes in water saturation using CT scanning. We compared our data to a number of models, and our relative permeability data compare most favorably with models in which hydrate occupies the pore bodies rather than the pore throats. Inverse modeling (using the data collected from the tests) will be performed to extend the relative permeability measurements.

Design and Implementation of Energized Fracture Treatment in Tight Gas Sands  

SciTech Connect

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

Short-term energy outlook, April 1999  

Science Conference Proceedings (OSTI)

The forecast period for this issue of the Outlook extends from April 1999 through December 2000. Data values for the first quarter 1999, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the April 1999 version of the Short-Term Integrated forecasting system (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the STIFS model. 25 figs., 19 tabs.

Short GRBs: Rates and luminosity function implications  

E-Print Network (OSTI)

We compare the luminosity function and rate inferred from the BATSE short hard bursts (SHBs) peak flux distribution with the redshift and luminosity distributions of SHBs observed by Swift/HETE II. The Swift/HETE II SHB sample is incompatible with SHB population that follows the star formation rate. However, it is compatible with a distribution of delay times after the SFR. This would be the case if SHBs are associated with the mergers of double neutron star (DNS) systems. DNS may be ``primordial'' or can form dynamically by binary exchange interaction in globular clusters during core collapse. The implied SHB rates that we find range from \\sim 8 to \\sim 30h_(70)^3 Gpc^(-3)yr^(-1). This rate is a much higher than what was previously estimated and, when beaming is taken into account, it is comparable to the rate of neutron star mergers estimated from statistics of binary pulsars. If GRBs are produced in mergers the implied rate practically guarantees detection by LIGO II and possibly even by LIGO I.

Short Rotation Woody Crops Program: Project summaries  

DOE Green Energy (OSTI)

This document is a compilation of summaries describing research efforts in the US Department of Energy's Short Rotation Woody Crops Program (SRWCP). The SRWCP is sponsored by DOE's Biofuels and Municipal Waste Technology Division and is field-managed at Oak Ridge National Laboratory. The SRWCP is an integrated basic research program with 18 field research projects throughout the United States. The overall objective of the program is to improve the productivity and increase the cost efficiency of growing and harvesting woody trees and shrubs. In a competitive technical review, 25 projects were chosen to form a new research program. Although some of the original projects have ended and new ones have begun, many of the long-term research projects still form the core of the SRWCP. This document contains individual summaries of each of the 18 research projects in the SRWCP from October 1985 to October 1986. Each summary provides the following information: name and address of the contracting institution, principal investigator, project title, current subcontract or grant number, period of performance, and annual funding through fiscal year 1986. In addition, each summary contains a brief description of the project rationale, objective, approach, status, and future efforts. A list of publications that have resulted from DOE-sponsored research follows many of the summaries.

Planetary and Other Short Binary Microlensing Events from the MOA Short Event Analysis  

E-Print Network (OSTI)

We present the analysis of four candidate short duration binary microlensing events from the 2006-2007 MOA Project short event analysis. These events were discovered in an analysis designed to find short timescale single lens events that may be due to free-floating planets. Three of these events are determined to be microlensing events, while the fourth is most likely caused by stellar variability. For each of the three microlensing events, the signal is almost entirely due to a brief caustic feature with little or no lensing attributable mainly to the lens primary. One of these events, MOA-bin-1, is due to a planet, and it is the first example of a planetary event in which stellar host is only detected through binary microlensing effects. The mass ratio, q = 4.9 \\pm 1.4 \\times 10^{-3}, is relatively large for a planetary system, and the star-planet separation, s = 2.10 \\pm 0.05, is the largest ever for a low magnification microlensing event.

Short Rotation Crops in the United States  

SciTech Connect

The report is based primarily on the results of survey questions sent to approximately 60 woody and 20 herbaceous crop researchers in the United States and on information from the U.S. Department of Energy?s Bioenergy Feedstock Development Program. Responses were received from 13 individuals involved in woody crops research or industrial commercialization (with 5 of the responses coming from industry). Responses were received from 11 individuals involved in herbaceous crop research. Opinions on market incentives, technical and non-technical barriers, and highest priority research and development areas are summarized in the text. Details on research activities of the survey responders are provided as appendices to the paper. Woody crops grown as single-stem systems (primarily Populus and Eucalyptus species) are perceived to have strong pulp fiber and oriented strand board markets, and the survey responders anticipated that energy will comprise 25% or less of the utilization of single-stem short-rotation woody crops between now and 2010. The only exception was a response from California where a substantial biomass energy market does currently exist. Willows (Salix species) are only being developed for energy and only in one part of the United States at present. Responses from herbaceous crop researchers suggested frustration that markets (including biomass energy markets) do not currently exist for the crop, and it was the perception of many that federal incentives will be needed to create such markets. In all crops, responses indicate that a wide variety of research and development activities are needed to enhance the yields and profitability of the crops. Ongoing research activities funded by the U.S. Department of Energy?s Bioenergy Feedstock Development Program are described in an appendix to the paper.

Can short sellers predict accounting restatements and foresee their severity  

E-Print Network (OSTI)

This dissertation investigates whether short sellers establish short positions prior to accounting restatement announcements and whether the levels of short interest are related to the severity of restatements. Using 565 firms with restatement disclosure during the period of 1995 to 2002 and matched control firms with no restatements announcements, I find that the level of short interest is higher for the sample firms compared to the control firms in the months surrounding the announcements. The level of short interest increases as the restatement announcement date approaches and declines thereafter. Related to severity of restatement, I find that the level of short interest in the pre-disclosure period is higher for restatements involving fraud and the revenue accounts. There exists limited evidence that the pre-disclosure level of short interest is positively associated with the number of quarters restated and the magnitude of the restatements. Finally, I find cumulative abnormal returns surrounding the announcements are more negative for restatement firms that have a higher level of short interest. These results suggest that short sellers are highly sophisticated investors who can see through accounting manipulation and consequently profit from their knowledge.

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

SciTech Connect

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

Laboratory study on the use of tire shreds and rubber-sand in backfills and reinforced soil applications. Final report  

Science Conference Proceedings (OSTI)

Millions of scrap tires are discarded annually in the United States, the bulk of which are currently landfilled or stockpiled. This consumes valuable landfill space, or, if improperly disposed, creates a fire hazard and provides a prolific breeding ground for rates and mosquitoes. The use of tire shreds as lightweight fill material can sharply reduce the tire disposal problem. The present study, based on laboratory testing and numerical modeling, examines the feasibility of incorporating tire shreds and rubber-sand mixtures as lightweight geomaterial in embankments and backfills.

Numerical modeling of gas migration into and through faulted sand reservoirs in Pabst Field (Main Pass East Block 259), northern Gulf of Mexico  

E-Print Network (OSTI)

The further exploration and development of Pabst Gas Field with faulted sand reservoirs require an understanding of the properties and roles of faults, particularly Low Throw near Vertical Faults (LTNVFs), in gas migration and accumulation at a reservoir scale. This study presents numerical modeling of gas migration and accumulation processes in Pabst Field. Based on studies of the reservoirs, structure, faults, and fluid properties of the field, reservoir scale modeling was performed to determine the gas supply style and the fault properties by means of hundreds of iterations in which the fault properties and gas supply pattern were modified to match the gas distribution obtained from modeling with the gas distribution inferred from seismic data constrained by well data and production data. This study finds that in the main three sand reservoirs of Pabst Field the overlying younger sands cut down into the underlying older sands, so that partial connections between the three sands allow gas communication among the sands. Meanwhile, three fault families break up the three sands into numerous compartments. A primary fault and large synthetic and antithetic faults act as gas migration pathways: the synthetic and antithetic faults are inlets for gas flow and the primary fault is an outlet, and LTNVFs act as barriers to gas flow. Modeling requires fault properties in the field to change while the field is formed. The porosity and permeability of the faults in Pabst Field are 10% and 0.1 md, respectively, during gas charging of the sand reservoirs. But when there is no gas charging and large gas columns are maintained, the porosity and permeability of the faults decrease to 6% and 0.001 md, respectively. Pabst Field probably has an impulse gas charge history. Fault opening and closing, gas charge and recharge, and replacement of gas by formation water may occur. A combination of stratigraphy, structure, overpressure and gas charge rate control gas migration style, gas charge history, and gas distribution in the field. The significance of the study is that this improved numerical approach for modeling gas migration into and through specifically faulted sand reservoirs fills the gap between basin modeling and production modeling.

Short fiction creative writing: storytelling with a film perspective  

E-Print Network (OSTI)

The research and material contained in this thesis will examine short story theory from current perspectives in the field and provide a response to questions posed about the composition of short fiction. A critical introduction will take into account these theories and lead into a collection of five short stories written from a filmmaking perspective. The collection of work provided represents an attempt to break stereotype in the construction and formatting of what is considered standard short story material. Focus for the collection concerns sensory perception, elements of film (flashback sequencing and extended exposition) and gender/race identity. Through the critical introduction and short story collection, the completed thesis will prove that the study and practice of creative writing cannot be regulated by a set of technical guidelines.

PLANETARY AND OTHER SHORT BINARY MICROLENSING EVENTS FROM THE MOA SHORT-EVENT ANALYSIS  

SciTech Connect

We present the analysis of four candidate short-duration binary microlensing events from the 2006-2007 MOA Project short-event analysis. These events were discovered as a by-product of an analysis designed to find short-timescale single-lens events that may be due to free-floating planets. Three of these events are determined to be microlensing events, while the fourth is most likely caused by stellar variability. For each of the three microlensing events, the signal is almost entirely due to a brief caustic feature with little or no lensing attributable mainly to the lens primary. One of these events, MOA-bin-1, is due to a planet, and it is the first example of a planetary event in which the stellar host is only detected through binary microlensing effects. The mass ratio and separation are q (4.9 {+-} 1.4) Multiplication-Sign 10{sup -3} and s = 2.10 {+-} 0.05, respectively. A Bayesian analysis based on a standard Galactic model indicates that the planet, MOA-bin-1Lb, has a mass of m{sub p} = 3.7 {+-} 2.1 M{sub Jup} and orbits a star of M{sub *} = 0.75{sub -0.41}{sup +}0{sup .33} M{sub Sun} at a semimajor axis of a = 8.3{sub -2.7}{sup +4.5} AU. This is one of the most massive and widest separation planets found by microlensing. The scarcity of such wide-separation planets also has implications for interpretation of the isolated planetary mass objects found by this analysis. If we assume that we have been able to detect wide-separation planets with an efficiency at least as high as that for isolated planets, then we can set limits on the distribution of planets in wide orbits. In particular, if the entire isolated planet sample found by Sumi et al. consists of planets bound in wide orbits around stars, we find that it is likely that the median orbital semimajor axis is >30 AU.

INTERPLANETARY NETWORK LOCALIZATIONS OF KONUS SHORT GAMMA-RAY BURSTS  

SciTech Connect

Between the launch of the Global Geospace Science Wind spacecraft in 1994 November and the end of 2010, the Konus-Wind experiment detected 296 short-duration gamma-ray bursts (including 23 bursts which can be classified as short bursts with extended emission). During this period, the Interplanetary Network (IPN) consisted of up to 11 spacecraft, and using triangulation, the localizations of 271 bursts were obtained. We present the most comprehensive IPN localization data on these events. The short burst detection rate, {approx}18 yr{sup -1}, exceeds that of many individual experiments.

Short Circuit Analysis of Induction Machines Wind Power Application  

Science Conference Proceedings (OSTI)

he short circuit behavior of Type I (fixed speed) wind turbine-generators is analyzed in this paper to aid in the protection coordination of wind plants of this type. A simple network consisting of one wind turbine-generator is analyzed for two network faults: a three phase short circuit and a phase A to ground fault. Electromagnetic transient simulations and sequence network calculations are compared for the two fault scenarios. It is found that traditional sequence network calculations give accurate results for the short circuit currents in the balanced fault case, but are inaccurate for the un-faulted phases in the unbalanced fault case. The time-current behavior of the fundamental frequency component of the short circuit currents for both fault cases are described, and found to differ significantly in the unbalanced and balanced fault cases

Short-term energy outlook: Annual supplement, 1987  

SciTech Connect

The Energy Information Administration (EIA) publishes forecasts of short-term energy supply, demand, and prices in the Short-Term Energy Outlook (Outlook). This volume, Short-Term Energy Outlook, Annual Supplement, (Supplement) discusses major changes in the forecasting methodology, analyzes previous forecast errors, and examines current issues that affect EIA's short-term energy forecasts. The principal users of the Supplement are managers and energy analysts in private industry and government. Chapter 2 evaluates the accuracy of previous short-term energy forecasts and the major assumptions underlying these forecasts published in the last 13 issues of the Outlook. Chapter 3 compares the EIA's present energy projections with past projections and with recent projections made by other forecasting groups. Chapter 4 analyzes the 1986 increase in residual fuel oil demand after 8 consecutive years of decline. Sectoral analysis shows where and why this increase occurred. Chapter 5 discusses the methodology, estimation, and forecasts of fossil fuel shares used in the generation of electricity. Chapter 6 presents an update of the methodology used to forecast natural gas demand, with an emphasis on sectoral disaggregation. Chapter 7 compares the current use of generation data as a representation of short-term electricity demand with proposed total and sectoral sales equations. 8 refs., 7 figs., 63 tabs.

Radium-226 and calcium uptake by crops grown in mixtures of sand and cay tailings from phosphate mining  

Science Conference Proceedings (OSTI)

Radium-226 is a naturally occurring radionuclide found in reclaimed clay and sand tailing from phosphate mining. Field studies were conducted to investigate the effects of sand/clay ratio (SCR), Ca supplement and organic amendments on the {sup 226}Ra concentration in turnip, banana pepper, cabbage, yellow squash, mustard, and alfalfa. For vegetables, treatment effects included SCR (2:1, 4:1, 6:1, and 8:1), phosphogypsum (PG) 0,22, and 134 Mg ha{sup {minus}1}, and peat 0,100, and 200 Mg ha{sup {minus}1}. For alfalfa grown in a 1:1 SCR mixture, treatments included organic amendments (control, peat, sewage slude, sawdust, composted sewage sludge, composted garbage and humate) applied at 44.8 Mg ha{sup {minus}1} (2.2 Mg ha{sup {minus}1} for humate). Plant {sup 226}Ra concentration tended to be higher in the 4:1 than in the 2:1 SCR mix but this depended on the crop an d the season. Organic amendments and PG had no effect (p<0.05) on the {sup 226}Ra concentration in vegetables and alfalfa. Mean {sup 226}Ra concentration in plant tissues ranged from 3.4 Bq kg{sup {minus}1} in banana pepper fruit to 31.1 Bq kg{sup {minus}1}. A quadratic relationship based on 631 observations was observed between {sup 226}Ra and Ca concentration in plant tissues. The {sup 226}Ra/Ca ratio in plant tissues ranged from 0.85 to 2.13 kBq {sup 226}Ra kg{sup {minus}1} Ca and decreased with increasing plant {sup 226}Ra. Results indicated that wide differences in plant {sup 226}Ca concentration were related more to differences in plant Ca levels than to soil factors. 21 refs., 1 fig., 6 tabs.

Use of Computed X-ray Tomographic Data for Analyzing the Thermodynamics of a Dissociating Porous Sand/Hydrate Mixture  

DOE R&D Accomplishments (OSTI)

X-ray computed tomography (CT) is a method that has been used extensively in laboratory experiments for measuring rock properties and fluid transport behavior. More recently, CT scanning has been applied successfully to detect the presence and study the behavior of naturally occurring hydrates. In this study, we used a modified medical CT scanner to image and analyze the progression of a dissociation front in a synthetic methane hydrate/sand mixture. The sample was initially scanned under conditions at which the hydrate is stable (atmospheric pressure and liquid nitrogen temperature, 77 K). The end of the sample holder was then exposed to the ambient air, and the core was continuously scanned as dissociation occurred in response to the rising temperature. CT imaging captured the advancing dissociation front clearly and accurately. The evolved gas volume was monitored as a function of time. Measured by CT, the advancing hydrate dissociation front was modeled as a thermal conduction problem explicitly incorporating the enthalpy of dissociation, using the Stefan moving-boundary-value approach. The assumptions needed to perform the analysis consisted of temperatures at the model boundaries. The estimated value for thermal conductivity of 2.6 W/m K for the remaining water ice/sand mixture is higher than expected based on conduction alone; this high value may represent a lumped parameter that incorporates the processes of heat conduction, methane gas convection, and any kinetic effects that occur during dissociation. The technique presented here has broad implications for future laboratory and field testing that incorporates geophysical techniques to monitor gas hydrate dissociation.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

Summary from the Short-Term Energy Outlook Summary from the Short-Term Energy Outlook EIA Home > Natural Gas > Natural Gas Weekly Update Natural Gas Summary from the Short-Term Energy Outlook This summary is based on the most recent Short-Term Energy Outlook released May 6, 2002. EIA projects that natural gas wellhead prices will average $2.73 per MMBtu in 2002 compared with about $4.00 per MMBtu last year (Short-Term Energy Outlook, May 2002). This projection reflects the sharp increases in spot and near-term futures prices in recent weeks. Average wellhead prices have risen 38 percent from $2.14 per MMBtu in February to an estimated $2.96 in April. Spot prices at the Henry Hub have increased to an even greater extent, rising more than $1.50 per MMBtu since early February. The upward price trend reflects a number of influences, such as unusual weather patterns that have led to increased gas consumption, and tensions in the Middle East and rising crude oil prices. Other factors contributing to the recent price surge include the strengthening economy, the increased capacity and planned new capacity of gas-burning power plants, and concerns about the decline in gas-directed drilling.

Short-term energy outlook: Quarterly projections. Second quarter 1995  

SciTech Connect

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent projections with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the second quarter of 1995 through the fourth quarter of 1996. Values for the first quarter of 1995, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data, compiled into the second quarter 1995 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service.

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

Science Conference Proceedings (OSTI)

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

Backside localization of open and shorted IC interconnections  

SciTech Connect

A new failure analysis technique has been developed for backside and frontside localization of open and shorted interconnections on ICs. This scanning optical microscopy technique takes advantage of the interactions between IC defects and localized heating using a focused infrared laser ({lambda} = 1,340 nm). Images are produced by monitoring the voltage changes across a constant current supply used to power the IC as the laser beam is scanned across the sample. The method utilizes the Seebeck Effect to localize open interconnections and Thermally-Induced Voltage Alteration (TIVA) to detects shorts. The interaction physics describing the signal generation process and several examples demonstrating the localization of opens and shorts are described. Operational guidelines and limitations are also discussed.

Testing Mass Varying Neutrino With Short Gamma Ray Burst  

E-Print Network (OSTI)

In this paper we study the possibility of probing for the absolute neutrino mass and its variation with short Gamma Ray Burst (GRB). We have calculated the flight time difference between a massive neutrino and a photon in two different approaches to mass varying neutrinos. Firstly we parametrize the neutrino mass as a function of redshift in a model independent way, then we consider two specific models where the neutrino mass varies during the evolution of the Quintessence fields. Our calculations show in general the value of the time delay is changed substantially relative to a constant neutrino mass. Furthermore our numerical results show that the flight time delay in these models is expected to be larger than the duration time of the short GRB, which opens a possibility of testing the scenario of mass varying neutrino with the short GRB.

General Relativistic Binary Merger Simulations and Short Gamma Ray Bursts  

E-Print Network (OSTI)

The recent localization of some short-hard gamma ray bursts (GRBs) in galaxies with low star formation rates has lent support to the suggestion that these events result from compact object binary mergers. We discuss how new simulations in general relativity are helping to identify the central engine of short-hard GRBs. Motivated by our latest relativistic black hole-neutron star merger calculations, we discuss a scenario in which these events may trigger short-hard GRBs, and compare this model to competing relativistic models involving binary neutron star mergers and the delayed collapse of hypermassive neutron stars. Distinguishing features of these models may help guide future GRB and gravitational wave observations to identify the nature of the sources.

Short-Termed Integrated Forecasting System: 1993 Model documentation report  

Science Conference Proceedings (OSTI)

The purpose of this report is to define the Short-Term Integrated Forecasting System (STIFS) and describe its basic properties. The Energy Information Administration (EIA) of the US Energy Department (DOE) developed the STIFS model to generate short-term (up to 8 quarters), monthly forecasts of US supplies, demands, imports exports, stocks, and prices of various forms of energy. The models that constitute STIFS generate forecasts for a wide range of possible scenarios, including the following ones done routinely on a quarterly basis: A base (mid) world oil price and medium economic growth. A low world oil price and high economic growth. A high world oil price and low economic growth. This report is written for persons who want to know how short-term energy markets forecasts are produced by EIA. The report is intended as a reference document for model analysts, users, and the public.

THE AFTERGLOW AND ENVIRONMENT OF THE SHORT GRB 111117A  

Science Conference Proceedings (OSTI)

We present multi-wavelength observations of the afterglow of the short GRB 111117A, and follow-up observations of its host galaxy. From rapid optical and radio observations, we place limits of r {approx}> 25.5 mag at {delta}t Almost-Equal-To 0.55 days and F{sub {nu}}(5.8 GHz) {approx}light curve at {delta}t {approx} 3-10 Degree-Sign (depending on the circumburst density). We conclude that Chandra observations of short GRBs are effective at determining precise positions and robust host galaxy associations in the absence of optical and radio detections.

Short-Term Wind Speed Forecasting for Power System Operations  

E-Print Network (OSTI)

Global large scale penetration of wind energy is accompanied by significant challenges due to the intermittent and unstable nature of wind. High quality short-term wind speed forecasting is critical to reliable and secure power system operations. This paper gives an overview of the current status of worldwide wind power developments and future trends, and reviews some statistical short-term wind speed forecasting models, including traditional time series models and advanced space-time statistical models. It also discusses the evaluation of forecast accuracy, in particular the need for realistic loss functions. New challenges in wind speed forecasting regarding ramp events and offshore wind farms are also presented.

E-Print Network (OSTI)

Using the Euclidean value of as a cosmological distance indicator, we derive the isotropic-equivalent characteristic peak luminosity of gamma-ray bursts both longer and shorter than 2 s. The short bursts have essentially the same characteristic peak luminosity of 0.6 x 10^51 erg (0.064s)^-1 as do the long bursts. This may apply also to bursts with durations less than 0.25 s. The local space density of short bursts is around three times lower than that of long bursts.

Short-term energy outlook: Annual supplement 1989  

SciTech Connect

This Supplement is published once a year as a complement to the Short-Term Energy Outlook, Quarterly Projections (Outlook). The purpose is to review the accuracy of the forecasts presented in the Outlook, make comparisons with other independent energy forecasts, and examine current energy topics that affect the forecasts. A brief description of the content of each chapter follows below: Chapter 2 evaluates the accuracy of the short-term energy forecasts published in the last 6 issues of the Outlook, for 1988/1989. Chapter 3 discusses the economics of the petrochemical feedstock market, and describes a new model which more fully captures the determinants of feedstock demand. Chapter 4 examines present and proposed new methods of forecasting short-term natural gas prices at the wellhead and spot prices. Chapter 5 discusses the modeling of natural demand in the short term. Chapter 6 discusses regional trends in the demand for fuel by electric utilities. Chapter 7 focuses on industrial coal use trends in recent years. Chapter 8 compares EIA's base case energy projections as published in the Outlook (89/2Q) with recent projections made by three other major forecasting groups. The chapter focuses on macroeconomic assumptions, primary energy demand, and primary energy supply, showing the differences and similarities in the four forecasts.

Short-Term Energy Outlook: Quarterly projections. Fourth quarter 1993  

SciTech Connect

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the fourth quarter of 1993 through the fourth quarter of 1994. Values for the third quarter of 1993, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data are EIA data published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications.

Short sequence motifs, overrepresented in mammalian conservednon-coding sequences  

SciTech Connect

Background: A substantial fraction of non-coding DNAsequences of multicellular eukaryotes is under selective constraint. Inparticular, ~;5 percent of the human genome consists of conservednon-coding sequences (CNSs). CNSs differ from other genomic sequences intheir nucleotide composition and must play important functional roles,which mostly remain obscure.Results: We investigated relative abundancesof short sequence motifs in all human CNSs present in the human/mousewhole-genome alignments vs. three background sets of sequences: (i)weakly conserved or unconserved non-coding sequences (non-CNSs); (ii)near-promoter sequences (located between nucleotides -500 and -1500,relative to a start of transcription); and (iii) random sequences withthe same nucleotide composition as that of CNSs. When compared tonon-CNSs and near-promoter sequences, CNSs possess an excess of AT-richmotifs, often containing runs of identical nucleotides. In contrast, whencompared to random sequences, CNSs contain an excess of GC-rich motifswhich, however, lack CpG dinucleotides. Thus, abundance of short sequencemotifs in human CNSs, taken as a whole, is mostly determined by theiroverall compositional properties and not by overrepresentation of anyspecific short motifs. These properties are: (i) high AT-content of CNSs,(ii) a tendency, probably due to context-dependent mutation, of A's andT's to clump, (iii) presence of short GC-rich regions, and (iv) avoidanceof CpG contexts, due to their hypermutability. Only a small number ofshort motifs, overrepresented in all human CNSs are similar to bindingsites of transcription factors from the FOX family.Conclusion: Human CNSsas a whole appear to be too broad a class of sequences to possess strongfootprints of any short sequence-specific functions. Such footprintsshould be studied at the level of functional subclasses of CNSs, such asthose which flank genes with a particular pattern of expression. Overallproperties of CNSs are affected by patterns in mutation, suggesting thatselection which causes their conservation is not always verystrong.

Characterization and utilization of hydrotreated products produced from the Whiterocks (Utah) tar sand bitumen-derived liquid  

SciTech Connect

The bitumen-derived liquid produced in a 4-inch diameter fluidized-bed reactor from the mined and crushed ore from the Whiterocks tar sand deposit has been hydrotreated in a fixed-bed reactor. The purpose was to determine the extent of upgrading as a function of process operating variable. A sulfided nickel-molybendum on alumina hydrodenitrogenation catalyst was used in all experiments. Moderately severe operating conditions were employed; that is, high reaction temperature (617--680 K) high reactor pressure (11.0--17.1 MPa) and low liquid feed rate (0.18--0.77 HSV); to achieve the desired reduction in heteroatom content. Detailed chemical structures of the bitumen-derived liquid feedstock and the hydrotreated total liquid products were determined by high resolution gas chromatography - mass spectrometry analyses. The compounds identified in the native bitumen included isoprenoids; bicyclic, tricycle, and tetracyclic terpenoids; steranes; hopanes; and perhydro-{beta}-carotenes. In addition, normal and branched alkanes and alkenes and partially dehydrogenated hydroaromatics were identified in the bitumen-derived liquid. The dominant pyrolysis reactions were: (1) the dealkylation of long alkyl side chains to form {alpha} - and isoolefins; and (2) the cleavage of alkyl chains linking aromatic and hydroaromatic clusters. Olefinic bonds were not observed in the hydrotreated product and monoaromatic hydrocarbons were the predominant aromatic species. The properties of the jet fuel fractions from the hydrotreated products met most of the jet fuel specifications. The cetane indices indicated these fractions would be suitable for use as diesel fuels.

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

SciTech Connect

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

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

Science Conference Proceedings (OSTI)

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