Factors that will influence oil and gas supply and demand in the 21st century  

Science Conference Proceedings (OSTI)

A recent report published by the National Petroleum Council (NPC) in the United States predicted a 50-60% growth in total global demand for energy by 2030. Because oil, gas, and coal will continue to be the primary energy sources during this time, the energy industry will have to continue increasing the supply of these fuels to meet this increasing demand. Achieving this goal will require the exploitation of both conventional and unconventional reservoirs of oil and gas in (including coalbed methane) an environmentally acceptable manner. Such efforts will, in turn, require advancements in materials science, particularly in the development of materials that can withstand high-pressure, high-temperature, and high-stress conditions.

Factors Influencing the Stability and Marketability of a Novel, Phytochemical-Rich Oil from the Açai Palm Fruit (Euterpe oleracea Mart.)  

E-Print Network (OSTI)

The açai palm fruit has recently become the focus of numerous research endeavors due to its extraordinary antioxidant content. However, little is known about the fruit’s phytochemical rich oil, which is a by-product of the açai pulp. Therefore, the aim of this study was to investigate the phytochemical content of açai oil and its relation to oxidative stability. A total of 206 mg/kg of chlorophylls, which included chlorophyll a as well as four chlorophyll derivatives were tentatively identified by HPLC in crude açai oil (CAO). Two predominant carotenoids (216 mg/kg ?-carotene and 177 mg/kg lutein) were also characterized in addition to ?-tocopherol (645 mg/kg). Initial investigations into oil stability focused upon the photooxidation of açai oil due to its significant chlorophyll content and findings demonstrated that the increases of nonanal were observed when phospholipids and polyphenolics were reduced. Subsequently, investigations into the interactions between phospholipids and lipophilic antioxidants and their contributions to the stability of açai oil were also assessed by isolating phytochemicals and selectively reconstituting the oil. Findings demonstrated a potential relationship between phospholipids and lipophilic antioxidants, but this was not conclusive. Advances in the processing of the açai pulp by-product created from the clarification process yielded a partially refined açai oil (RAO). The stability of both RAO and CAO as a result of autoxidation were compared to other common food oils (olive, canola, and soybean) and primary and secondary oxidation data suggested CAO was most stable. The difference in the stability of the two açai oils was also investigated by blending these oils and assessing oxidation. An increased stability was demonstrated in the blended RAO, which suggested a significant antioxidant contribution from the CAO. With such similar lipophilic compositions in CAO and RAO, it is theorized that the driving factor behind the stability of CAO can be attributed to its water soluble antioxidant content. While further investigations are required to fully comprehend the interactions of açai oil phytochemicals, these experiments provide insight into the phytochemical content and stability of açai oil. The understanding and information obtained in these studies is geared at increasing the marketability of açai oil as a food ingredient.

Conductivity factor in the electrostatic coalescence of crude oil emulsions  

E-Print Network (OSTI)

Resolution of emulsions through electrostatic coalescence has been in practice for over fifty years. Through dimensional analysis of a charged droplet under an external field, the electrical conductivity was determined to be an influencing parameter on the rate of coalescence. Using previously established procedures, the potential for enhancement of the electrostatic coalescence rate for oil/water emulsions of highly refined oils and different grades of crude oils was explored using a 2-L vertically-oriented, cylindrical coalescer. The electrical conductivity of each phase of the water-in-oil emulsion was varied to determine their effects on the rate of coalescence. Both light and intermediate grades of crude oil emulsions were modified using conductivity modifiers, formerly used as antistatic addiitvties , to change the conductivity of the oil phase. Addition of the active component of the conductivity modifier in the ppm range increased the coalescence rate from 200% to 500% as compared to the base case (no additive). The refined oil emulsion was varied using water in different conductivity ranges. As anticipated, the rate of coalescence increased with water conductivity of the water. This is at least partially due to the unstable nature of these emulsions.

Factors influencing county level household fuelwood use  

Science Conference Proceedings (OSTI)

This study explains household fuelwood consumption behavior at the county level by linking it to economic and demographic conditions in counties. Using this link, counties are identified where potential fuelwood use problems and benefits are greatest. A probit equation estimates household probability of wood use (percent woodburners in a county heating degree days, household income, nonwood fuel price, fuelwood price, percent forest land, population density, and fraction of households using various types of heating equipment. A linear-in-parameters equation estimates average wood consumed by a woodburner based on county heating degree days, household income, percent forest land, and price of nonwood fuel divided by fuelwood price. Parameters are estimated using fuelwood use data for individual households from a 1908-81 nationwide survey. The probit equation predicts percentage of wood burns well over a wide range of county conditions. The wood consumption equation overpredicts for counties with high income and high population density (over 6000 persons per square mile). The model shows average woodburning per household over all households decreases with increasing population density, and the influence of county economic characteristics varies with density.

First Factor Impacting Distillate Prices: Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

8 8 Notes: World oil prices have tripled from their low point in December 1998 to August this year, pulling product prices up as well. But crude prices are expected to show a gradual decline as increased oil production from OPEC and others enters the world oil market. We won't likely see much decline this year, however, as prices are expected to end the year at about $30 per barrel. The average price of WTI was almost $30 per barrel in March, but dropped to $26 in April as the market responded to the additional OPEC production. However, prices strengthened again, averaging almost $32 in June, $30 in July, and $31 in August. The continued increases in crude oil prices indicate buyers are having trouble finding crude oil, bidding higher prices to obtain the barrels available.

Propane Prices Influenced by Crude Oil and Natural Gas  

Gasoline and Diesel Fuel Update (EIA)

6 6 Notes: Propane prices have been high this year for several reasons. Propane usually follows crude oil prices more closely than natural gas prices. As crude oil prices rose beginning in 1999, propane has followed. In addition, some early cold weather this year put extra pressure on prices. However, more recently, the highly unusual surge in natural gas prices affected propane supply and drove propane prices up. Propane comes from two sources of supply: refineries and natural gas processing plants. The very high natural gas prices made it more economic for refineries to use the propane they normally produce and sell than to buy natural gas. The gas processing plants found it more economic to leave propane in the natural gas streams than to extract it for sale separately.

Factors influencing trace element composition in human teeth  

SciTech Connect

The authors recently compiled and reviewed the literature published in or after 1978 for 45 major, minor, and trace elements in human teeth as a part of an International Atomic Energy Agency (IAEA) study. The purpose of this paper is to discuss the various factors that influence the concentration levels of certain trace elements in human teeth. The sampling practices and analytical techniques that are applicable for trace element analysis are also discussed. It is also our intention to identify reference range of values, where data permit such conclusions. The scrutiny was designed to identify only the healthy permanent teeth, and values from teeth with fillings, caries, or periodontal diseases were eliminated.

East Asia now important factor in oil world  

SciTech Connect

On one level the countries of East Asia are vital components of the global energy equation specifically in regard to oil production and are directly affected by the entire world. But equally they are independent nation states with their own particular energy characteristics, making each country worthy of specific consideration. There is not necessarily a regional dimension to every energy issue facing the countries and one must be careful to avoid facile generalizations about the region. For the purpose of this article, East Asia will be defined as Japan, the newly industrialized economies of Hong Kong, Singapore, Taiwan and South Korea; the industrializing economies of Malaysia, Thailand, Indonesia, and the Philippines, and the remainder, excluding the Indian subcontinent, but including China, Burma, and Viet Nam. Together these countries contain some one third of the world's population and produce around a fifth of the world gross domestic product (GDP). For the past 3 decades, they have made up the fastest growing economic region of the world. However, East Asia cannot be considered in isolation from the Middle East. No examination of any energy topic can ignore the importance of that area.

Influence of site-specific geology on oil shale fragmentation experiments at the Colony Mine, Garfield County, Colorado  

SciTech Connect

The Los Alamos National Laboratory executed 19 intermediate scale cratering experiments in oil shale at the Colony Mine in Garfield County, Colorado. These experiments have led to a better understanding of fracture characteristics and fragmentation of in situ oil shale by use of a conventional high explosive. Geologic site characterization included detailed mapping, coring, and sample analyses. Site-specific geology was observed to be a major influence on the resulting crater geometry. The joint patterns at the experimental site frequently defined the final crater symmetry. Secondary influences included vugs, lithology changes, and grade fluctuations in the local stratigraphy. Most experiments, in both the rib and floor, were conducted to obtain data to investigate the fragmentation results within the craters. The rubble was screened for fragment-size distributions. Geologic features in proximity to the explosive charge had minimal effect on the rubble due to the overpowering effect of the detonation. However, these same features became more influential on the fracture and rubble characteristics with greater distances from the shothole. Postshot cores revealed a direct relationship between the grade of the oil shale and its susceptibility to fracturing. The Colony Mine experiments have demonstrated the significant role of geology in high explosive/oil shale interaction. It is probable that this role will have to be considered for larger applications to blast patterns and potential problems in retort stability in the future of oil shale development.

Relative Condition Factors of Fish as Bioindicators One Year after the Deepwater Horizon Oil Spill  

E-Print Network (OSTI)

Creel surveys were performed over a three week period in late spring, 2011, in the Lafourche and Calcasieu area estuaries of the Louisiana Gulf Coast. Weights and lengths were measured for black drum (Pogonias cromis), red drum (Sciaenops ocellatus), and spotted seatrout (Cynoscion nebulosus), and relative condition factors were calculated relative to expected weights from the long term (5 year) Louisiana data for each species. A normal relative condition factor is 1.00. The mean relative condition factors in the Lafourche area were black drum, 0.955 (0.020); red drum, 0.955 (0.011); spotted seatrout, 0.994 (0.009). In the Calcasieu area, the mean relative condition factors were black drum, 0.934 (0.017); red drum, 0.965 (0.014); spotted seatrout, 0.971 (0.010). Uncertainties are in parentheses. Results suggest that the abundance of primary food sources for black drum and red drum in Lafourche, including oysters and crab, were likely affected by the oil spill and continued to be reduced one year later.

Factors influencing biological treatment of MTBE contaminated ground water  

DOE Green Energy (OSTI)

Methyl tert-butyl ether (MTBE) contamination has complicated the remediation of gasoline contaminated sites. Many sites are using biological processes for ground water treatment and would like to apply the same technology to MTBE. However, the efficiency and reliability of MTBE biological treatment is not well documented. The objective of this study was to examine the operational and environmental variables influencing MTBE biotreatment. A fluidized bed reactor was installed at a fuel transfer station and used to treat ground water contaminated with MTBE and gasoline hydrocarbons. A complete set of chemical and operational data was collected during this study and a statistical approach was used to determine what variables were influencing MTBE treatment efficiency. It was found that MTBE treatment was more sensitive to up-set than gasoline hydrocarbon treatment. Events, such as excess iron accumulation, inhibited MTBE treatment, but not hydrocarbon treatment. Multiple regression analysis identified biomass accumulation and temperature as the most important variables controlling the efficiency of MTBE treatment. The influent concentration and loading of hydrocarbons, but not MTBE, also impacted MTBE treatment efficiency. The results of this study suggest guidelines for improving MTBE treatment. Long cell retention times in the reactor are necessary for maintaining MTBE treatment. The onset of nitrification only occurs when long cell retention times have been reached and can be used as an indicator in fixed film reactors that conditions favorable to MTBE treatment exist. Conversely, if the reactor can not nitrify, it is unlikely to have stable MTBE treatment.

Determination of influence factors and accident rates for the Armored Tractor/Safe Secure Trailer  

Science Conference Proceedings (OSTI)

Operating environments, such as road type, road location, and time of day, play an important role in the observed accident rates of heavy trucks used in general commerce. These same factors influence the accident rate of the Armored Tractor/Safe Secure Trailer (AT/SST) used by the Department of Energy to transport hazardous cargos within the continental United States. This report discusses the development of accident rate influence factors. These factors, based on heavy trucks used in general commerce, are used to modify the observed overall AT/SST accident rate to account for the different operating environments.

The history of oil shale development was examined by gathering relevant research literature for an Unconventional Oil Resource Repository. This repository contains over 17,000 entries from over 1,000 different sources. The development of oil shale has been hindered by a number of factors. These technical, political, and economic factors have brought about R&D boom-bust cycles. It is not surprising that these cycles are strongly correlated to market crude oil prices. However, it may be possible to influence some of the other factors through a sustained, yet measured, approach to R&D in both the public and private sectors.

In January 1986, the Becon Construction Company - an open-shop contractor based in Houston, Texas - mobilized a work force to a construction project location at the Belridge Oil Field, near Bakersfield, California. The construction craftsmen and helpers in Becon's work force were expected to improve their level of productivity as the work proceeded because of the knowledge and skills that they would acquire as a result of the repetitive nature of the work. As it was originally organized, the Becon HOTS project represented almost a pure laboratory environment in which to collect data concerning the learning effect on worker productivity as well as to statistically isolate the impact on productivity of such external factors as weather, absenteeism, turnover, and especially work methods improvement techniques and pay incentives. From the outset of the HOTS project, the project manager had established an accurate system to quantitatively measure and compare the total manhours that each crew - civil, mechanical, electrical, and prefabrication -- performed at individual HOTS construction locations. Additionally, it was initially assumed that the project manager would be relatively free to implement changes to the job site conditions involving incentive pay and work methods improvement. The subsequent effect of these changes on the productivity of separate work crews could then be evaluated in terms of measured manhours per crew per HOTS.

Influence of chemical characterization of oil shale solids on understanding water quality impacts  

SciTech Connect

Synfuels technologies will yield products and effluents that are a function of the raw material being processed and the process variables. Chemical and mineralogic characterization of solids generated in synfuels production provide valuable insight into health and environmental impacts associated with synfuels processing (coal liquefaction or gasification and shale oil extraction). This report deals with considerations relating to leachate generation from solid wastes, but the suggested research approach is applicable to understanding the nature and extent of all effluents from synfuels operations. Solid characterization studies of one raw shale core and two spent shale cores from Occidental Oil Shale, Inc.'s Logan Wash site are described. These data are used to determine the effect of processing on the shale solids and also to evaluate a variety of water quality issues associated with in situ processing. The importance of solid characterization studies in developing an understanding of effluent composition and behavior and subsequently defining environmental impacts is described.

SUBTASK 1.7 EVALUATION OF KEY FACTORS AFFECTING SUCCESSFUL OIL PRODUCTION IN THE BAKKEN FORMATION, NORTH DAKOTA PHASE II  

Science Conference Proceedings (OSTI)

Production from the Bakken and Three Forks Formations continues to trend upward as forecasts predict significant production of oil from unconventional resources nationwide. As the U.S. Geological Survey reevaluates the 3.65 billion bbl technically recoverable estimate of 2008, technological advancements continue to unlock greater unconventional oil resources, and new discoveries continue within North Dakota. It is expected that the play will continue to expand to the southwest, newly develop in the northeastern and northwestern corners of the basin in North Dakota, and fully develop in between. Although not all wells are economical, the economic success rate has been near 75% with more than 90% of wells finding oil. Currently, only about 15% of the play has been drilled, and recovery rates are less than 5%, providing a significant future of wells to be drilled and untouched hydrocarbons to be pursued through improved stimulation practices or enhanced oil recovery. This study provides the technical characterizations that are necessary to improve knowledge, provide characterization, validate generalizations, and provide insight relative to hydrocarbon recovery in the Bakken and Three Forks Formations. Oil-saturated rock charged from the Bakken shales and prospective Three Forks can be produced given appropriate stimulation treatments. Highly concentrated fracture stimulations with ceramic- and sand-based proppants appear to be providing the best success for areas outside the Parshall and Sanish Fields. Targeting of specific lithologies can influence production from both natural and induced fracture conductivity. Porosity and permeability are low, but various lithofacies units within the formation are highly saturated and, when targeted with appropriate technology, release highly economical quantities of hydrocarbons.

Factors affecting in-situ recovery of hydrocarbons from oil shale  

SciTech Connect

Batch thermal solution of Hell's Hole Canyon oil shale in hydrocarbon solvents has been studied at temperatures of from 274/sup 0/ to 410/sup 0/C. Three solvents were used: cyclohexane; 1,2,3,4-tetrahydronaphthalene; and creosote oil. In 24-hour, constant-temperature runs under autogenous pressure, each solvent was found to be capable of removing over 90% of the original organic material at extraction temperatures of from 360 to 375/sup 0/C. Cyclohexane extraction resulted in somewhat greater yields than tetralin extraction in runs below 365/sup 0/C but approximately the same yields as tetralin at higher extraction temperatures. With one oil shale sample, virtually identical yields were observed in both cyclohexane and tetralin extractions. This finding suggests that mass-transfer restrictions within some oil shales may restrict the yield regardless of the solvent used. Carbon-13 NMR analyses of the spent shales showed that the aromaticity of the residual organic material in tetralin-extracted shale increased slightly from the raw shale value of 0.27 and remained essentially constant at a value of 0.31 increased. In constant temperature runs of 24-hour duration, the aromaticity of an oil shle sample increased from the raw oil shale value of 0.17 to 0.28 after cyclohexane extraction at 326/sup 0/C, while a tetralin-extracted sample of the same oil shale had an aromaticity of only 0.20 after extraction at 321/sup 0/C. The nitrogen content of the cyclohexane extracts, which ranged from 1.58 to 2.24%, was comparable to that of values reported in the literature for shale oils. The tetralin extracts had somewhat lower nitrogen content, ranging from 0.58 to 1.95%. Extract nitrogen content generally increased with extraction temperature. 55 references, 58 figures, 22 tables.

Factors Affecting the Relationship between Crude Oil and Natural Gas Prices (released in AEO2010)  

Reports and Publications (EIA)

Over the 1995-2005 period, crude oil prices and U.S. natural gas prices tended to move together, which supported the conclusion that the markets for the two commodities were connected. Figure 26 illustrates the fairly stable ratio over that period between the price of low-sulfur light crude oil at Cushing, Oklahoma, and the price of natural gas at the Henry Hub on an energy-equivalent basis.

International Energy Outlook 2001 - World Oil Markets  

Gasoline and Diesel Fuel Update (EIA)

World Oil Markets World Oil Markets picture of a printer Printer Friendly Version (PDF) In the IEO2001 forecast, periodic production adjustments by OPEC members are not expected to have a significant long-term impact on world oil markets. Prices are projected to rise gradually through 2020 as the oil resource base is expanded. Crude oil prices remained above $25 per barrel in nominal terms for most of 2000 and have been near $30 per barrel in the early months of 2001. Prices were influenced by the disciplined adherence to announced cutbacks in production by members of the Organization of Petroleum Exporting Countries (OPEC). OPECÂ’s successful market management strategy was an attempt to avoid a repeat of the ultra-low oil price environment of 1998 and early 1999. Three additional factors contributed to the resiliency of oil prices in

Factors influencing helium measurements for detection of control rod failures in BWR  

SciTech Connect

Much effort has been made to minimize the number and consequences of fuel failures at nuclear power plants. The consequences of control rod failures have also gained an increased attention. In this paper we introduce a system for on-line surveillance of control rod integrity which has several advantages comparing to the surveillance methods available today in boiling water reactors (BWRs). This system measures the helium released from failed control rods containing boron carbide (B4C). However, there are a number of factors that might influence measurements, which have to be taken into consideration when evaluating the measured data. These factors can be separated into two groups: 1) local adjustments, made on the sampling line connecting the detector to the off-gas system, and 2) plant operational parameters. The adjustments of the sample line conditions include variation of gas flow rate and gas pressure in the line. Plant operational factors that may influence helium measurements can vary from plant to plant. The factors studied at Leibstadt nuclear power plant (KKL) were helium impurities in injected hydrogen gas, variation of the total off-gas flow and regular water refill. In this paper we discuss these factors and their significance and present experimental results of measurements at KKL. (authors)

Performance of Anidolic Daylighting Systems in tropical climates - Parametric studies for identification of main influencing factors  

Science Conference Proceedings (OSTI)

Making daylight more available in buildings is highly desirable, not only for reasons of energy-efficiency, but also for improvement of occupants' health and well-being. Core-daylighting, that is daylight provision in areas situated at considerable distances from facades and windows, is currently one of the main challenges in sustainable building design. Anidolic Daylighting Systems (ADSs) are one very promising technology in the field of core-daylighting, but commercial solutions that are not only well-performing but also financially competitive are not yet widely available. This article presents results of parametric studies on Anidolic Integrated Ceilings (AICs), a special type of ADS, for identification of main influencing factors. The article describes a reliable method for simulating ADS and AIC performance under given sky conditions. Various simulation results for the example location Singapore are discussed in detail, it is concluded that the main influencing factors are coating material, system dimensions and external obstruction, and those influencing factors' potential impacts are quantified. It is shown that AIC overall efficiencies can reach up to almost 50% in Singapore. The essentially new results presented in this article can be of great help to architects, engineers and scientists in the future, when it comes to precisely dimensioning ADS for various buildings and daylight conditions.

Influence of irrigation and weathering reactions on the composition of percolates from retorted oil shale in field lysimeters  

SciTech Connect

Major cations, anions, trace elements and dissolved organic C were measured in percolate from retorted oil shale collected from irrigated lysimeters in the field at Anvil Points, Colorado, over a two year period. The investigations indicated that chemical equilibrium was not established over the monitoring period and major changes occurred in percolate composition as a function of applied water volume and water residence time in the shale. Field and laboratory studies indicated that several factors contributed to changes in the chemistry of the shale on weathering, including recarbonization of the surface horizons with atmospheric CO/sub 2/ and the activities of microorganisms in surface and subsurface horizons. However, the principal mechanism responsible for the decreases in pH and salt concentrations appeared to be the conversion of major quantities of sulfide in the retorted shale to sulfate through a thiosulfate intermediate.

DEVELOPMENT OF FINE PARTICULATE EMISSION FACTORS AND SPECIATION PROFILES FOR OIL AND GAS FIRED COMBUSTION SYSTEMS  

SciTech Connect

This report provides results from the second year of this three-year project to develop dilution measurement technology for characterizing PM2.5 (particles with aerodynamic diameter smaller than 2.5 micrometers) and precursor emissions from stationary combustion sources used in oil, gas and power generation operation. Detailed emission rate and chemical speciation tests results for a gas turbine, a process heater, and a commercial oil/gas fired boiler are presented. Tests were performed using a research dilution sampling apparatus and traditional EPA methods. A series of pilot tests were conducted to identify the constraints to reduce the size of current research dilution sampler for future stack emission tests. Based on the test results, a bench prototype compact dilution sampler developed and characterized in GE EER in August 2002.

This paper examines the short-run relationships between oil prices and GCC stock markets. Since GCC countries are major world energy market players, their stock markets may be susceptible to oil price shocks. To account for the fact that stock markets may respond nonlinearly to oil price shocks, we have examined both linear and nonlinear relationships. Our findings show that there are significant links between the two variables in Qatar, Oman, and UAE. Thus, stock markets in these countries react positively to oil price

Influence of time-dependent factors in the evaluation of critical infrastructure protection measures.  

Science Conference Proceedings (OSTI)

The examination of which protective measures are the most appropriate to be implemented in order to prevent, protect against, respond to, and recover from attacks on critical infrastructures and key resources typically involves a comparison of the consequences that could occur when the protective measure is implemented to those that could occur when it is not. This report describes a framework for evaluation that provides some additional capabilities for comparing optional protective measures. It illustrates some potentially important time-dependent factors, such as the implementation rate, that affect the relative pros and cons associated with widespread implementation of protective measures. It presents example results from the use of protective measures, such as detectors and pretrained responders, for an illustrative biological incident. Results show that the choice of an alternative measure can depend on whether or not policy and financial support can be maintained for extended periods of time. Choice of a time horizon greatly influences the comparison of alternatives.

An analysis of factors that influence community college students' attitudes toward technology  

E-Print Network (OSTI)

This study investigated the factors that influence community college students' attitudes toward technology, particularly in teaching and learning experiences. Studies on post-secondary students' attitudes reported in the literature are limited. Factors cited previously as having an effect on attitudes towards technology and toward computers included: gender; age; presence of a computer in the home; completion of a formal technology course; and comfort with technology. The subjects in this study were 372 students in freshman level credit English classes in the five colleges of the North Harris Montgomery Community College District located in the greater metropolitan Houston area. Previous research instruments and studies to measure students' attitudes toward technology were reviewed. A modified version of the Secondary Students Attitudes' Toward Technology (SSATT) was developed for this study because of the content, reliability, and applicability to the postsecondary population. The instrument was administered in the spring of 2005. The fact that 95.4% of the participants reported having a computer at home and that 70.2% reported having had a formal technology class provided insight into the integration of technology in the lives of this community college sample. A correlation matrix of all variables and analysis of variance were performed. Factor analyses were performed to identify subcomponents of the instrument. Eight factors were identified: (1) need for technology competence, (2) technology benefits, (3) negative aspects of technology, (4) technology and the workplace, (5) impact of increased use of technology, (6) video games, (7) technology and job creation, and (8) technology and safety. A conclusion of the study was that neither age nor gender had a significant effect on the post-secondary students' attitudes toward technology, which differs from the findings in some of the previous studies. Females reported being as comfortable, if not more so, with technology in teaching and learning experiences as the males in the study. Exposure to technology, completion of a formal technology class, and the use of computers appeared to positively affect community college students' attitudes toward technology.

Factors influencing Kemp's ridley sea turtle (Lepidochelys kempii) distribution in nearshore waters and implications for management  

E-Print Network (OSTI)

Post-pelagic juvenile and subadult Kemp's ridley sea turtles (Lepidochelys kempii) (20-40 cm straight carapace length) utilize nearshore waters of the northwestern Gulf of Mexico as nursery or developmental feeding grounds. This study utilizes 10 years of entanglement netting data to characterize long-term abundance and distribution of Kemp's ridley sea turtles at index habitats in this region. Netting surveys were conducted during April-October 1993-2002, primarily at Sabine Pass, Texas and Calcasieu Pass, Louisiana. Additionally, this study takes an ecosystem-based approach to understanding factors influencing Kemp's ridley in-water abundance and distribution via the development of a conceptual model incorporating data on nesting dynamics, environmental conditions, prey availability, and predation pressure. Overall monthly mean ridley catch-per-unit-effort (CPUE) peaked in the beginning of summer (April-June), probably in response to rising water temperatures and seasonal occurrence of blue crab prey. Annual mean ridley CPUE across all study areas peaked in 1994, 1997, 1999 and 2002, suggesting a 2-3 year cycle in abundance that may be related to patterns in clutch size or hatch success at the Rancho Nuevo, Mexico nesting beach. However, ridley CPUE in nearshore waters remained relatively constant or decreased slightly even as number of hatchlings released from Rancho Nuevo increased exponentially. Annual declines in Texas strandings since 1994 and subsequent increases in Florida counterparts since 1995 suggest a shift in ridley distribution from the western to eastern Gulf in recent years. Significant declines in ridley CPUE at Sabine Pass since 1997 coincided with a concurrent reduction in blue crab size, but a similar trend was not detected at Calcasieu Pass. Kemp's ridley occurrence at study sites was not significantly related to shrimping activity/by-catch. There also were no biologically significant relationships between Kemp's ridley CPUE and abiotic factors, nor were ridleys deterred from utilizing areas frequented by bull sharks. Overall, nesting dynamics and prey availability were conceptual model components appearing to have the greatest influence on nearshore ridley occurrence.

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

Science Conference Proceedings (OSTI)

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

A Study of Circadian Rhythm and Meteorological Factors Influencing Acute Myocardial Infarction  

E-Print Network (OSTI)

The circadian rhythm in the occurrence of acute myocardial infarction (AMI) was assessed in three hundred and twenty three patients admitted with AMI during the two-year period June 1992 to May 1994. The influence of the following meteorological, solar-geophysical and cosmic parameters in the causation of an infarct was also considered : (1) surface pressure (2) maximum temperature (3) minimum temperature (4) relative humidity (5) cosmic ray index (6) geomagnetic aa index (7) solar flares and (8) sunspot number. A well pronounced diurnal variability in AMI with a peak in the morning hours (6-12 a.m.) was seen. Further analysis of the data by considering one-hour periods revealed the presence of a smaller evening (10 p.m.) increase in incidence, i.e., the existence of a bimodal circadian rhythm. The simultaneous occurrence of the well documented semi-diurnal rhythm in surface pressure and incidence of acute myocardial infarction were evident. This may be one of the factors involved in the causation of the smaller evening peak-the reasons for which were unclear till now. Month-to-month variation in surface pressure was also found to be significantly correlated with incidence of acute myocardial infarction. Recognition of a circadian rhythm in the onset of AMI suggests the need for enhanced pharmacological protection during the vulnerable periods. Significant correlations were also found between monthly incidence of AMI and month-to-month variation of cosmic ray index and solar flare counts. The pattern of incidence of AMI was seen to be modified by full moon and new moon. There was no association between maximum temperature, minimum temperature or relative humidity and incidence of AMI.

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

E-Print Network (OSTI)

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

DEVELOPMENT OF FINE PARTICULATE EMISSION FACTORS AND SPECIATION PROFILES FOR OIL AND GAS-FIRED COMBUSTION SYSTEMS  

SciTech Connect

In 1997, the United States Environmental Protection Agency (EPA) promulgated new National Ambient Air Quality Standards (NAAQS) for particulate matter, including for the first time particles with aerodynamic diameter smaller than 2.5 micrometers ({micro}m) referred to as PM2.5. PM2.5 in the atmosphere also contributes to reduced atmospheric visibility, which is the subject of existing rules for siting emission sources near Class 1 areas and new Regional Haze rules. There are few existing data regarding emissions and characteristics of fine aerosols from oil, gas and power generation industry combustion sources, and the information that is available is generally outdated and incomplete. Traditional stationary source air emission sampling methods tend to underestimate or overestimate the contribution of the source to ambient aerosols because they do not properly account for primary aerosol formation, which occurs after the gases leave the stack. Primary aerosol includes both filterable particles that are solid or liquid aerosols at stack temperature plus those that form as the stack gases cool through mixing and dilution processes in the plume downwind of the source. These deficiencies in the current methods can have significant impacts on regulatory decision-making. PM2.5 measurement issues were extensively reviewed by the American Petroleum Institute (API) (England et al., 1998), and it was concluded that dilution sampling techniques are more appropriate for obtaining a representative particulate matter sample from combustion systems for determining PM2.5 emission rate and chemical speciation. Dilution sampling is intended to collect aerosols including those that condense and/or react to form solid or liquid aerosols as the exhaust plume mixes and cools to near-ambient temperature immediately after the stack discharge. These techniques have been widely used in recent research studies. For example, Hildemann et al. (1994) and McDonald et al. (1998) used filtered ambient air to dilute the stack gas sample followed by 80-90 seconds residence time to allow aerosol formation and growth to stabilize prior to sample collection and analysis. More accurate and complete emissions data generated using the methods developed in this program will enable more accurate source-receptor and source apportionment analysis for PM2.5 National Ambient Air Quality Standards (NAAQS) implementation and streamline the environmental assessment of oil, gas and power production facilities. The overall goals of this program were to: (1) Develop improved dilution sampling technology and test methods for PM2.5 mass emissions and speciation measurements, and compare results obtained with dilution and traditional stationary source sampling methods. (2) Develop emission factors and speciation profiles for emissions of fine particulate matter, especially organic aerosols, for use in source-receptor and source apportionment analyses. (3) Identify and characterize PM2.5 precursor compound emissions that can be used in source-receptor and source apportionment analyses.

Socio-economic and communication factors influencing the diffusion of solar-energy equipment among California homeowners  

Science Conference Proceedings (OSTI)

This dissertation explores the influence of socio-economic, communication, and social-psychological factors on the diffusion of solar-energy equipment among California homeowners. There were four specific objectives: (1) to critique previous studies on the diffusion of solar technology; (2) to critique fundamental aspects of current diffusion models and to formulate an alternative diffusion perspective; (3) to use the proposed theoretical perspective to predict solar diffusion; and (4) to test certain of the proposed predictions about solar diffusion. Data used to test some of the predictions were based on a state-wide random survey of 812 California homeowners. The dissertation presents two major findings. First, some of the best predictors of the solar-diffusion process were found to be age, socio-economic status, knowing solar owners, ownership of a swimming pool, utility costs, efficacy towards the energy situation, voluntary simplicity, energy consciousness, community size, and perceived community interest in solar. Second, these predictors were found to be strongly related to socio-economic status. The present study argues that these predictors are in fact post indicators of socio-economic status. Thus, whereas many of the previous studies tended to underestimate the influence of socio-economic factors, this study was able to demonstrate the crucial influence of socio-economic factors in determining the rate and pattern of solar diffusion. The data show that household solar-energy equipment is basically an innovation for high and medium socio-economic groups. The implications of these findings with regard to previous studies, policy, and future research are also discussed.

Dominant Middle East oil reserves critically important to world supply  

Science Conference Proceedings (OSTI)

This paper reports that the location production, and transportation of the 60 million bbl of oil consumed in the world each day is of vital importance to relations between nations, as well as to their economic wellbeing. Oil has frequently been a decisive factor in the determination of foreign policy. The war in the Persian Gulf, while a dramatic example of the critical importance of oil, is just the latest of a long line of oil-influenced diplomatic/military incidents, which may be expected to continue. Assuming that the world's remaining oil was evenly distributed and demand did not grow, if exploration and development proceeded as efficiently as they have in the U.S., world oil production could be sustained at around current levels to about the middle of the next century. It then would begin a long decline in response to a depleting resource base. However, the world's remaining oil is very unevenly distributed. It is located primarily in the Eastern Hemisphere, mostly in the Persian Gulf, and much is controlled by the Organization of Petroleum Exporting Countries. Scientific resource assessments indicate that about half of the world's remaining conventionally recoverable crude oil resource occurs in the Persian Gulf area. In terms of proved reserves (known recoverable oil), the Persian Gulf portion increase to almost two-thirds.

Identification of factors that influence the stiffness of high-damping elastomer seismic isolation bearings  

Science Conference Proceedings (OSTI)

During the past decade, high-damping elastomer, steel-laminated seismic isolation bearings have gained acceptance as a device for isolating large buildings and structures from earthquake damage. In the United States, architectural engineering firms custom design isolators for each project and ten have the isolators manufactured by one of less than a hand-full of manufactures. The stiffness of the bearing is the single most important design parameter that the molded bearing must meet because it determines the fundamental frequency of the isolation system. This paper reports on recent research that examined several factors that cause real and potential variations to the stiffness of the bearing. The resulting changes to the fundamental frequency of the isolated structure are quantified for each factor. The following were examined: (1) dimensional tolerances, (2) frequency effects, (3) temperature effects, (4) cyclical effects, and (5) aging effects. It was found that geometric variations barely affect the stiffness whereas temperature variations greatly affect the stiffness.

QUANTITY OF RADIATION REACHING GONADAL AREAS DURING THERAPY. IV. FACTORS INFLUENCING OVARY DOSE  

SciTech Connect

Attempts were made to evaluate the circumstances influencing the quantity of radiation reaching the ovaries during dermatologic radiation therapy, and to devise effective methods for reducing the amount to well within acceptable limits. Measurements were made in a specially constructed, life-size, pressed- wood (masonite) phantom which could be used in almost any position that might be assumed by man during routine x-ray therapy, and with provisions for insertion of an ionization chamber at the anatomic site representing an ovary. The various parameters which might influence ovary dose during conventional dermatologic x- ray procedures that were studied included: x-ray quality (kvp), tube current (ma), beam collimation and field size, shielding, angle of the beam in relation to the ovaries, and proximity of treatment site to the ovaries. Ovarian dose was measured during irradiation of the face, upper chest, and back, using each of the parameters alone and then in various combinations. The results, presented in tables and graphs, show that in order to minimize ovary dose during dermatologic x-ray therapy, one should utilize lower tube kilovoltage, softer radiation, appropriate collimation, effective shielding (minimizing area of field irraiated) with no added filtration, increased distance between the x-ray beam axis and the ovaries, and angling on the x-ray tube away from the ovaries. The gonad dose can best be reduced by exerting all of these simple and inexpensive means every time dermatologic radiation is administered. However, from these measurements it was evident that of the body areas studied, some may be irradiated without fear of exceeding even the max permissible dose to the ovaries, whereas other areas cannot be treated with x-rays without overdosing the ovaries regardless of the pre cautions taken.

Effects of No-Till on Yields as Influenced by Crop and Environmental Factors  

Science Conference Proceedings (OSTI)

Th is research evaluated diff erences in yields and associated downside risk from using no-till and tillage practices. Yields from 442 paired tillage experiments across the United States were evaluated with respect to six crops and environmental factors including geographic location, annual precipitation, soil texture, and time since conversion from tillage to no-till. Results indicated that mean yields for sorghum [Sorghum bicolor (L.) Moench] and wheat (Triticum aestivum L.) with no-till were greater than with tillage. In addition, no-till tended to produce similar or greater mean yields than tillage for crops grown on loamy soils in the Southern Seaboard and Mississippi Portal regions. A warmer and more humid climate and warmer soils in these regions relative to the Heartland, Basin and Range, and Fruitful Rim regions appear to favor no-till on loamy soils. With the exception of corn (Zea mays L.) and cotton (Gossypium hirsutum L.) in the Southern Seaboard region, no-till performed poorly on sandy soils. Crops grown in the Southern Seaboard were less likely to have lower no-till yields than tillage yields on loamy soils and thus had lower downside yield risk than other farm resource regions. Consistent with mean yield results, soybean [Glycine max (L.) Merr.] and wheat grown on sandy soils in the Southern Seaboard region using no-till had larger downside yield risks than when produced with no-till on loamy soils. Th e key fi ndings of this study support the hypothesis that soil and climate factors impact no-till yields relative to tillage yields and may be an important factor infl uencing risk and expected return and the adoption of the practice by farmers.

World oil prices and production trends in AEO2010 World oil prices and production trends in AEO2010 Annual Energy Outlook 2010 with Projections to 2035 World oil prices and production trends in AEO2010 In AEO2010, the price of light, low-sulfur (or “sweet”) crude oil delivered at Cushing, Oklahoma, is tracked to represent movements in world oil prices. EIA makes projections of future supply and demand for “total liquids,” which includes conventional petroleum liquids—such as conventional crude oil, natural gas plant liquids, and refinery gain—in addition to unconventional liquids, which include biofuels, bitumen, coal-to-liquids (CTL), gas-to-liquids (GTL), extra-heavy oils, and shale oil. World oil prices can be influenced by a multitude of factors. Some tend to be short term, such as movements in exchange rates, financial markets, and weather, and some are longer term, such as expectations concerning future demand and production decisions by the Organization of the Petroleum Exporting Countries (OPEC). In 2009, the interaction of market factors led prompt month contracts (contracts for the nearest traded month) for crude oil to rise relatively steadily from a January average of $41.68 per barrel to a December average of $74.47 per barrel [38].

A review of the factors influencing the physicochemical characteristics of underground coal gasification  

Science Conference Proceedings (OSTI)

In this article, the physicochemical characteristics of the oxidation zone, the reduction zone, and the destructive distillation and dry zone in the process of underground coal gasification (UCG) were explained. The effect of such major factors as temperature, coal type, water-inrush or -intake rate, the quantity and quality of wind blasting, the thickness of coal seams, operational pressure, the length, and the section of gasification gallery on the quality of the underground gas and their interrelationship were discussed. Research showed that the temperature conditions determined the underground gas compositions; the appropriate water-inrush or -intake rate was conducive to the improvement in gas heat value; the properties of the gasification agent had an obvious effect on the compositions and heat value of the product gas. Under the cyclically changing pressure, heat losses decreased by 60%, with the heat efficiency and gasification efficiency being 1.4 times and 2 times those of constant pressure, respectively. The test research further proved that the underground gasifier with a long channel and a big cross-section, to a large extent, improved the combustion-gasification conditions.

Fuzzy Comprehensive Evaluation Model and Influence Factors Analysis on Comprehensive Performance of Green Buildings  

E-Print Network (OSTI)

A green building involves complex system engineering including energy efficiency and energy utilization, water-saving and water utilization, material-saving and material utilization, and land-saving and indoor environment quality and operation management. In order to solve problems of subjectivity, uncertainty and impossibility of quantitative analysis when evaluating green building, this study establishes a multi-level fuzzy evaluation model by means of fuzzy mathematics method to analyze the comprehensive performance of green building according to the index system of “Evaluation Standard for Green Building”. Combined with the technique scheme of the first China green building demonstration project, the result proves to be in accordance with the pre-evaluation of experts. It shows that the fuzzy comprehensive evaluation method is reasonable and feasible to evaluate the comprehensive performance of green building. The evaluation result is the same as the pre-evaluation result. Factors with high weights have larger effects on the results. This proves that the guideline should be the first reference mode in the future engineering practice so as to realize optimization of green building performance.

Factors influencing the microwave pulse duration in a klystron-like relativistic backward wave oscillator  

SciTech Connect

In this paper, we analyze the factors that affect the microwave pulse duration in a klystron-like relativistic backward wave oscillator (RBWO), including the diode voltage, the guiding magnetic field, the electron beam collector, the extraction cavity, and the gap between the electron beam and the slow wave structure (SWS). The results show that the microwave pulse duration increases with the diode voltage until breakdown occurs on the surface of the extraction cavity. The pulse duration at low guiding magnetic field is generally 5-10 ns smaller than that at high magnetic field due to the asymmetric electron emission and the larger energy spread of the electron beam. The electron beam collector can affect the microwave pulse duration significantly because of the anode plasma generated by bombardment of the electron beam on the collector surface. The introduction of the extraction cavity only slightly changes the pulse duration. The decrease of the gap between the electron beam and the SWS can increase the microwave pulse duration greatly.

Factors Influencing Time Resolution of Scintillators and Ways to Improve Them  

E-Print Network (OSTI)

The renewal of interest in Time of Flight Positron Emission Tomography (TOF-PET), as well as the necessity to precisely tag events in high energy physics (HEP) experiments at future colliders are pushing for an optimization of all factors affecting the time resolution of the whole acquisition chain comprising the crystal, the photo detector, and the electronics. The time resolution of a scintillator-based detection system is determined by the rate of photo electrons at the detection threshold, which depends on the time distribution of photons being converted in the photo detector. The possibility to achieve time resolution of about 100 ps Full Width at Half Maximum (FWHM) requires an optimization of the light production in the scintillator, the light transport and its transfer from the scintillator to the photo detector. In order to maximize the light yield, and in particular the density of photons in the first nanosecond, while minimizing the rise time and decay time, particular attention must be paid to the...

Investigating Indoor Radon Levels and Influencing Factors in Primary Schools of Zulfi City, Saudi Arabia  

SciTech Connect

Measurement of indoor Concentrations were performed in Zulfi city of Saudi Arabia, using CR-39 track etch detectors. This investigation focused on the influence of different parameters, namely different locations, school categories, school building types, and room type as well as on the existence of differences in radon concentration at floor levels. We divided the Zulfi city into five regions, keeping in mind their geographical locations between Tuwaiq Mountains and Al-Thuwayrat sands. The measured average radon concentrations for regions 1-5 respectively are: 87.0{+-}14.2 Bq/m{sup 3}, 83.4{+-}6.0 Bq/m{sup 3}, 61.6{+-}6.4 Bq/m{sup 3}, 63.7{+-}5.4 Bq/m{sup 3} and 87.5{+-}6.Bq/m{sup 3} and the minimum concentrations are 28.0 Bq/m{sup 3}, 5.5 Bq/m{sup 3}, 1.1 Bq/m{sup 3}, 1.0 Bq/m{sup 3} and 24 Bq/m{sup 3} respectively. These results are still within normal limits and below the action level of 148 Bqm{sup -3} set by the U.S. Environmental Protection Agency (EPA). A test of significance using Minitab program was applied to investigate if radon levels in regions are significantly different from each other. We tried all combinations, and found the following results. The ''within regions''(different location) test yielded, region 2 is not significant versus region ''1''(p = 0.783) and versus region ''5''(P = 0.646), whereas it is significant versus region ''3''(P = 0.0160) and also versus region ''4''(p = 0.018). We investigated government and rented school's building also and none was found significantly different (p = 0.052). Floors of the same building were tested in order to examine the radon concentration as a function of storey level. No significant difference was observed at floor levels (p = 0.009). When girl's schools versus Boys and kindergartens schools were tested they were found significantly different. It is believed that this significant difference is due to geographical nature of the area, since most of the girl's schools were selected from regions 2 and 3, these regions are relatively close to the Tuwaiq mountains whereas other regions are near to the Al-Thuwayrat sands.

DEVELOPMENT OF FINE PARTICULATE EMISSION FACTORS AND SPECIATION PROFILES FOR OIL AND GAS-FIRED COMBUSTION SYSTEMS  

SciTech Connect

This report provides results from the first year of this three-year project to develop dilution measurement technology for characterizing PM2.5 (particles with aerodynamic diameter smaller than 2.5 micrometers) and precursor emissions from stationary combustion sources used in oil, gas and power generation operations. Detailed emission rate and chemical speciation test results for a refinery gas-fired process heater and plans for cogeneration gas turbine tests and pilot-scale tests are presented. Tests were performed using a research dilution sampling apparatus and traditional EPA methods to compare PM2.5 mass and chemical speciation. Test plans are presented for a gas turbine facility that will be tested in the fourth quarter of 2002. A preliminary approach for pilot-scale tests is presented that will help define design constraints for a new dilution sampler design that is smaller, lighter, and less costly to use.

The gender gap on concept inventories in physics: what is consistent, what is inconsistent, and what factors influence the gap?  

E-Print Network (OSTI)

We review the literature on the gender gap on concept inventories in physics. Across studies, men consistently score higher on pre-tests of the Force Concept Inventory (FCI) and Force and Motion Conceptual Evaluation (FMCE) by about 10%, and in most cases score higher on post-tests as well, also by about 10%. The average difference in normalized gain is about 6%. This difference is much smaller than the average difference in normalized gain between traditional lecture and interactive engagement (25%), but is large enough that it could impact the results of studies comparing the effectiveness of different teaching methods. Based on our analysis of 24 published articles comparing the impact of 34 factors that could potentially influence the gender gap, no single factor is sufficient to explain the gap. Several high-profile studies that have claimed to account for or reduce the gender gap have failed to be replicated, suggesting that isolated claims of explanations of the gender gap should be interpreted with ca...

Studies on the impact, detection, and control of microbiology influenced corrosion related to pitting failures in the Russian oil and gas industry. Final CRADA report.  

DOE Green Energy (OSTI)

The objectives of the Project are: (1) to design effective anti-corrosion preparations (biocides, inhibitors, penetrants and their combinations) for gas- and oil-exploration industries; (2) to study a possibility of development of environmentally beneficial ('green') biocides and inhibitors of the new generation; (3) to develop chemical and microbiological methods of monitoring of sites at risk of corrosion; and (4) to evaluate potentialities in terms of technology, raw materials and material and technical basis to set up a production of effective anti-corrosion preparations of new generation in Russia. During the four years of the project 228 compounds and formulations were synthesized and studied in respect to their corrosion inhibiting activity. A series of compounds which were according to the Bubble tests more efficient (by a factor of 10-100) than the reference inhibitor SXT-1102, some possessing the similar activity or slightly better activity than new inhibitor ??-1154? (company ONDEO/Nalco). Two synthetic routes for the synthesis of mercaptopyrimidines as perspective corrosion inhibitors were developed. Mercaptopyrimidine derivatives can be obtained in one or two steps from cheap and easily available precursors. The cost for their synthesis is not high and can be further reduced after the optimization of the production processes. A new approach for lignin utilization was proposed. Water-soluble derivative of lignin can by transformed to corrosion protective layer by its electropolymerization on a steel surface. Varying lignosulfonates from different sources, as well as conditions of electrooxidation we proved, that drop in current at high anodic potentials is due to electropolymerization of lignin derivative at steel electrode surface. The electropolymerization potential can be sufficiently decreased by an increase in ionic strength of the growing solution. The lignosulfonate electropolymerization led to the considerable corrosion protection effect of carbon steel. More than three times decrease of corrosion rate on steel surface was observed after lignosulfonate electropolymerization, exceeding protective effect of standard commercially available corrosion inhibitor. Solikamsky lignin could be a promising candidate as a base for the development of the future green corrosion inhibitor. A protective effect of isothiazolones in compositions with other biocides and inhibitors was investigated. Additionally to high biocidal properties, combination of kathon 893 and copper sulfate may also produce a strong anticorrosion effect depending on concentrations of the biocides. Based on its joint biocidal and anticorrosion properties, this combination can be recommended for protection of pipelines against carbon dioxide-induced corrosion. By means of linear polarization resistance test, corrosion properties of biocides of different classes were studied. Isothiazolones can be recommended for treating oil-processing waters in Tatarstan to curb carbon dioxide - induced corrosion. A laboratory research on evaluation of the efficiency of biocides, inhibitors and penetrants by biological and physical-and-chemical methods has been carried out. It was shown that action of corrosion inhibitors and biocides strongly depends on character of their interaction with mineral substances available in waters on oil-exploration sites. It was found that one of approaches to designing environmentally safe ('green') antimicrobial formulations may be the use of synergetic combinations, which allow one to significantly decrease concentrations of biocides. It was shown that the efficacy of biocides and inhibitors depends on physicochemical characteristics of the environment. Anticorrosion and antimicrobial effects of biocides and inhibitors depended in much on the type of medium and aeration regimen. Effects of different biocides, corrosion inhibitors. penetrants and their combinations on the biofilm were investigated. It has been shown that minimal inhibiting concentrations of the reagents for the biofilm are much higher than those for aquatic mic

Oil from rock  

SciTech Connect

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

Oil spill response resources  

E-Print Network (OSTI)

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

International Energy Outlook 1999 - World Oil Markets  

Gasoline and Diesel Fuel Update (EIA)

oil.gif (4669 bytes) oil.gif (4669 bytes) A moderate view of future oil market developments is reflected in IEO99. Sustained high levels of oil prices are not expected, whereas continued expansion of the oil resource base is anticipated. The crude oil market was wracked with turbulence during 1998, as prices fell by one-third on average from 1997 levels. Even without adjusting for inflation, the world oil price in 1998 was the lowest since 1973. The declining oil prices were influenced by an unexpected slowdown in the growth of energy demand worldwide—less than any year since 1990—and by increases in oil supply, particularly in 1997. Although the increase in world oil production in 1998 was smaller than in any year since 1993, efforts to bolster prices by imposing further limits on production were

Copyrolysis of Seyitomer-lignite and safflower seed: influence of the blending ratio and pyrolysis temperature on product yields and oil characterization  

SciTech Connect

Pyrolytic behaviors of biomass/coal mixtures were investigated under a heating rate of 7{sup o}C min{sup -1}, over a range of pyrolysis temperatures between 400 and 700{sup o}C, and the blending ratio of coal in mixtures was varied between 0 and 100 wt %. The results indicated that considerable synergistic effects were observed during the copyrolysis in a fixed-bed reactor leading to an increase in the oil yield at lower than coal blending ratios of 33%. At the lower blending coal ratio conditions, the oil yields are higher than the expected ones, calculated as the sum of oil fractions produced by pyrolysis of each separated component. The maximum pyrolysis oil yield of 39.5% was obtained with 5% of lignite mixed with safflower seed. The obtained oils are characterized by Fourier transform infrared spectroscopy, {sup 1}H nuclear magnetic resonance, gas chromatography mass spectrometry, and elemental analysis. These findings can potentially help to understand and predict the behavior of coal/biomass blends in practical liquefaction systems. 33 refs., 8 figs., 4 tabs.

Winter Crude Oil and  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: While the relatively low stock forecast (although not as low as last winter) adds some extra pressure to prices, the price of crude oil could be the major factor affecting heating oil prices this winter. The current EIA forecast shows residential prices averaging $1.29 this winter, assuming no volatility. The average retail price is about 7 cents less than last winter, but last winter included the price spike in November 2000, December 2000, and January 2001. Underlying crude oil prices are currently expected to be at or below those seen last winter. WTI averaged over $30 per barrel last winter, and is currently forecast to average about $27.50 per barrel this winter. As those of you who watch the markets know, there is tremendous uncertainty in the amount of crude oil supply that will be available this winter. Less

Oil reserves  

SciTech Connect

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

Unconventional Oil and Gas Resources  

Science Conference Proceedings (OSTI)

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

Influence of technological factors on statics of hydrogen sulfide absorption from coke-oven gas by the ammonia process  

SciTech Connect

The basic technological factors that determine the effectiveness of hydrogen sulfide absorption from coke-oven gas by the cyclic ammonia process are the initial H/sub 2/S content of the gas, the degree of purification, the absorption temperature and the NH/sub 3/ and CO/sub 2/ contents of the absorbent solution. The effects of these factors on the statics of hydrogen sulfide absorption are studied. The investigation is based on the phase-equilibrium distributions of components in the absorption-desorption gas-cleaning cycle. The mathematical model is presented which includes the solution of a system of chemical equilibrium equations for reactions in the solution, material balances, and electrical neutrality. 4 references, 5 figures, 1 table.

Oil dependence and Thai foreign-policy behavior during the Arab-Israeli war of October 1973  

SciTech Connect

The purpose of this study is to explain Thai foreign-policy behavior toward the Arab-Israeli conflict during the Arab oil embargo of 1973-1974 in the wake of the October 1973 War. The major hypothesis is that Thai foreign policy behavior shifted from a neutral to a pro-Arab position after the Arab oil embargo. This shift was motivated by Thai oil-import dependence on OAPEC (Organization of Arab Petroleum Exporting Countries). Oil has assumed an economic as well as a political dimension. Therefore, its political influence over the oil-dependent states cannot be dismissed. Thai foreign-policy behavior in the Arab-Israeli conflict is analyzed through the use of the dependence approach, which contends that external reliance is a potent factor for explaining behavior of actors. Thailand's foreign-policy stand is first delineated through the use of documents containing policy statements by Thai delegates to the United Nations. It was found that although Thai public policy statements were never bluntly anti-Israel, they moved from between neutrality before the oil crisis to a pro-Arab position after the oil crisis of 1973-1974. This shift of Thailand's foreign policy behavior position was then measured against its UN voting records. Results of the voting analysis indicated that the shifting of Thai foreign policy behavior during the October war was motivated by Thailand's oil-import dependence.

Solar retorting of oil shale  

DOE Green Energy (OSTI)

A detailed analysis of technical and economic factors solar retorting of oil shale shows that such a process should be technically feasible and, depending on the grade of the shale, should improve the fuel yield from the oil shale by 10 to 40%, compared to one of the best competing surface ay for the incremental processes. The improved oil yield should more than pay for the incremental cost associated with adding the solar collection system. An experiment is described in which solar energy is used to retort oil shale, and the experimental results show that yields of better than 110% Fischer Assay are achievable. An advanced design for a solar oil-shale retort is also discussed.

Distillate and Spot Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: This slide shows the strong influence crude oil prices have on retail distillate prices. The price for distillate fuel oil tracks the crude price increases seen in 1996 and the subsequent fall in 1997 and 1998. Distillate prices have also followed crude oil prices up since the beginning of 1999. Actual data show heating oil prices on the East Coast in June at $1.20 per gallon, up 39 cents over last June. However, if heating oil prices are following diesel, they may be up another 5 cents in August. That would put heating oil prices about 40 cents over last August prices. Crude oil prices are only up about 25 cents in August over year ago levels. The extra 15 cents represents improved refiner margins due in part to the very low distillate inventory level.

Influence of the nucleon-nucleon collision geometry on the determination of the nuclear modification factor for nucleon-nucleus and nucleus-nucleus collisions  

Science Conference Proceedings (OSTI)

The influence of the underlying nucleon-nucleon collision geometry on evaluations of the nuclear overlap function (TAB) and number of binary collisions (Ncoll) is studied. A narrowing of the spatial distribution of the hard-partons with large light-cone fraction x in nucleons leads to a downward correction for Ncoll and TAB, which in turn, results in an upward correction for the nuclear modification factor RAB. The size of this correction is estimated for several experimentally motivated nucleon-nucleon overlap functions for hard-partons. It is found to be significant in peripheral nucleus-nucleus and nucleon-nucleus collisions, and is much larger at the LHC energy of {radical}s = 5.5 TeV than for the RHIC energy of {radical}s = 200 GeV. The implications for experimental measurements are also discussed.

Safe recycling of used oil  

SciTech Connect

It`s not just recovery of used oil, but how you recover it, that ultimately determines the impact on the environment. No matter what recycling technology is employed, there are environmental/economic factors that come into play. One is the distance to the end user. Sending the used oil to a nearby plant (e.g. a local asphalt manufacturer as opposed to a distant refiner) both reduces hauling costs and the potential for a spill occurring during transport. Management practices of the used oil recycler, pollution control, insurance coverage and environmental compliance record are other factors in evaluating recovery options. Generators need to be careful about who is collecting their used oil, because they can be held liable for mismanagement.

Identifying Socio-ecological Factors Influencing the Use of Prescribed Fire to Maintain and Restore Ecosystem Health in Texas, USA and Northern Chihuahua, Mexico  

E-Print Network (OSTI)

There is a critical need for more studies to identify socio-ecological drivers that affect conservation and management of fire adapted ecosystems, yet studies that identify such variables and explore their interaction in specific systems are not only scarce but limited to only a few systems. Although information on the socio-ecological effects of prescribed fire application exists, there is no integrative framework that simultaneously considers the interplay between social and ecological factors affecting the use of prescribed fires. Fire suppression, together with other human and natural disturbances in grassland systems that are adapted to episodic fire, are the major factors that have contributed to the recruitment of woody species into grasslands worldwide. Even though the ecology of restoring these fire prone systems back to a grassland state is becoming clearer, the major hurdle to reintroducing historic fire at a landscape scale is its social acceptability. To address these deficiencies, I studied the socio-ecological factors influencing the use of prescribed fire in Texas, USA and Chihuahua, Mexico using a combination of quantitative and qualitative approaches to examine how social and ecological factors affect ecosystem conservation and management of semi-arid grassland systems. For the Texas case study I used quantitative survey data analyzed using logistic regression models and structural equation models. For the Mexico case study I used qualitative interviews gathered using a snowball network sampling approach and coded them based on the analytic themes of land cover change, institutional failure, market drivers, and population dynamics. Results from the Texas case study suggest that risk taking orientation and especially, perceived support from others when implementing prescribed burns, play important roles in determining attitudes towards the use of high-intensity prescribed fires, which are sometimes needed to restore ecosystems. Results from the Texas case study also highlight how membership in Prescribed Burn Associations (PBAs) influence land manager decisions regarding the use of prescribed fire by reducing concerns over lack of skills, knowledge and resources. Results emphasize the potential for PBAs to reduce risk concerns regarding the application of prescribed fire and are relevant to management of brush encroached areas. Through PBAs, effective landscape-scale solutions to the brush encroachment problem can be achieved in Texas. Results from the Mexico case study show how fire stopped effectively being a driving factor on this system decades ago. Socio-political and ecological changes at the national, and international level produced changes in land use disrupting historical fire patterns and contributing to the ecological deterioration of the area. Droughts combined with poor management practices have depleted the fuel needed to carry a fire. Landowners also face safety and legal concerns but in most cases, even if a landowner decided to implement a prescribed burn, an ecological threshold has been crossed and current fine fuel loads (grass) are insufficient to carry a fire that is sufficiently intense to reduce brush cover and restore grassland and savanna ecosystems. Based on my findings I can conclude that ecologically sound adaptive management and social capital are fundamental components of the livelihoods of landowners and land managers in both case studies. Work and investment that is focused on strengthening this social capital will have the most profound effects in maintaining the integrity of grassland systems at a landscape scale.

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

Science Conference Proceedings (OSTI)

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

DATA MINING AT THE NEBRASKA OIL & GAS COMMISSION  

Science Conference Proceedings (OSTI)

The purpose of this study of the hearing records is to identify factors that are likely to impact the performance of a waterflood in the Nebraska panhandle. The records consisted of 140 cases. Most of the hearings were held prior to 1980. Many of the records were incomplete, and data believed to be key to estimating waterflood performance such as Dykstra-Parson permeability distribution or relative permeability were absent. New techniques were applied to analyze the sparse, incomplete dataset. When information is available, but not clearly understood, new computational intelligence tools can decipher correlations in the dataset. Fuzzy ranking and neural networks were the tools used to estimate secondary recovery from the Cliff Farms Unit. The hearing records include 30 descriptive entries that could influence the success or failure of a waterflood. Success or failure is defined by the ratio of secondary to primary oil recovery (S/P). Primary recovery is defined as cumulative oil produced at the time of the hearing and secondary recovery is defined as the oil produced since the hearing date. Fuzzy ranking was used to prioritize the relevance of 6 parameters on the outcome of the proposed waterflood. The 6 parameters were universally available in 44 of the case hearings. These 44 cases serve as the database used to correlate the following 6 inputs with the respective S/P. (1) Cumulative Water oil ratio, bbl/bbl; (2) Cumulative Gas oil ratio, mcf/bbl; (3) Unit area, acres; (4) Average Porosity, %; (5) Average Permeability, md; (6) Initial bottom hole pressure, psi. A 6-3-1 architecture describes the neural network used to develop a correlation between the 6 input parameters and their respective S/P. The network trained to a 85% correlation coefficient. The predicted Cliff Farms Unit S/P is 0.315 or secondary recovery is expected to be 102,700 bbl.

Statistical and Realistic Numerical Model Investigations of Anthropogenic and Climatic Factors that Influence Hypoxic Area Variability in the Gulf of Mexico  

E-Print Network (OSTI)

The hypoxic area in the Gulf of Mexico is the second largest in the world, which has received extensive scientific study and management interest. Previous modeling studies have concluded that the increased hypoxic area in the Gulf of Mexico was caused by the increased anthropogenic nitrogen loading of the Mississippi River; however, the nitrogen-area relationship is complicated by many other factors, such as wind, river discharge, and the ratio of Mississippi to Atchafalaya River flow. These factors are related to large-scale climate variability, and thus will not be affected by regional nitrogen reduction efforts. In the research presented here, both statistical (regression) and numerical models are used to study the influence of anthropogenic and climate factors on the hypoxic area variability in the Gulf of Mexico. The numerical model is a three-dimensional, coupled hydrological-biogeochemical model (ROMS-Fennel). Results include: (1) the west wind duration during the summer explain 55% of the hypoxic area variability since 1993. Combined wind duration and nitrogen loading explain over 70% of the variability, and combined wind duration and river discharge explain over 85% of the variability. (2) The numerical model captures the temporal variability, but overestimates the bottom oxygen concentrations. The model shows that the simulated hypoxic area is in agreement with the observations from the year 1991, as long as hypoxia is defined as oxygen concentrations below 3 mg/L rather than below 2 mg/L. (3) The first three modes from an Empirical Orthogonal Function (EOF) analysis of the numerical model output results explain 62%, 8.1% and 4.9% of the variability of the hypoxic area. The Principle Component time series is cross-correlated with wind, dissolved inorganic nitrogen concentration and river discharge. (4) Scenario experiments with the same nitrogen loading, but different duration of upwelling favorable wind, indicate that the upwelling favorable wind is important for hypoxic area development. However, a long duration of upwelling wind decreases the area. (5) Scenario experiments with the same nitrogen loading, but different discharges, indicate that increasing river discharge by 50% increases the area by 42%. Additionally, scenario experiments with the same river discharge, but different nitrogen concentrations, indicate that reducing the nitrogen concentration by 50% decreases the area by 75%. (6) Scenario experiments with the same nitrogen loading, but different flow diver- sions, indicate that if the Atchafalaya River discharges increased to 66.7%, the total hypoxic area increases the hypoxic area by 30%, and most of the hypoxic area moved from east to west Louisiana shelf. Additionally, if the Atchafalaya River discharge decreased to zero, the total hypoxic area increases by 13%. (7) Scenario experiments with the same nitrogen loading, but different nitrogen forms, indicate that if all the nitrogen was in the inorganic forms, the hypoxic area increases by 15%. These results have multiple implications for understanding the mechanisms that control the oxygen dynamics, reevaluating management strategies, and improving the observational methods.

Underwater tanker ballast water/oil separation  

SciTech Connect

The invention contemplates tranferring ballast water contaminated with entrained or emulsified oil to an underwater disengagement zone operating on the water displacement principle, as exemplified by an underwater storage tank having an upwardly convex shell with an opening in its bottom through which water can move into and out of the shell as the volume of oil enclosed within the storage zone fluctuates. The ballast mixture of water and oil is introduced into the disengagement zone, where it separates under the influence of gravity into separate oil and water phases. The oil layer rises to a point from which it can be recovered, while the separated water flows out of the open bottom of the zone into the body of water. (2 claims)

Crude-oil market report  

SciTech Connect

The crude oil market has been both quieter and thinner during the past few months. Various factors, including OPEC restraints, settlement of the British coal strike, and dollar exchange rates, have been stabilizing, although erratic output by Iran and the Soviet Union have caused fluctuations in prices. Higher gasoline prices have triggered a preference for sweet crudes and a possible shortage during the summer motoring season. Oil stocks appear to be at the bottom now, but restocking activities will probably not cause shortages. The author forecasts a continued weak market. 2 tables.

Oil prices in a new light  

Science Conference Proceedings (OSTI)

For a clear picture of how oil prices develop, the author steps away from the price levels to which the world is accustomed, and evaluates scientifically. What makes prices jump from one notch to another The move results from a political or economic shock or the perception of a particular position by the futures market and the media. The shock could range from a war or an assassination to a promise of cooperation among OPEC members (when believed by the market) or to speculation about another failure at an OPEC meeting. In the oil market, only a couple of factual figures can provide a floor to the price of oil. The cost of production of oil in the Gulf is around $2 to $3/bbl, and the cost of production of oil (capital and operating costs) in key non-OPEC areas is well under $10/bbl. With some adjustments for transport and quality, a price range of $13/bbl to $16/bbl would correspond to a reasonable sustainable floor price. The reason for prices above the floor price has been a continuous fear of oil supply interruptions. That fear kept prices above the floor price for many years. The fear factor has now almost fully disappeared. The market has gone through the drama of the Iranian Revolution, the Iran-Iraq war, the tanker war, the invasion of Kuwait, and the expulsions of the Iraqis. And still the oil flowed -- all the time. It has become abundantly clear that fears above the oil market were unjustified. Everyone needs to export oil, and oil will flow under the worst circumstances. The demise of the fear factor means that oil prices tend toward the floor price for a prolonged period.

Feasibility evaluation of downhole oil/water separator (DOWS) technology.  

SciTech Connect

The largest volume waste stream associated with oil and gas production is produced water. A survey conducted by the American Petroleum Institute estimated that 20.9 billion barrels of produced water were disposed of in 1985 (Wakim 1987). Of this total, 91% was disposed of through disposal wells or was injected for enhanced oil recovery projects. Treatment and disposal of produced water represents a significant cost for operators. A relatively new technology, downhole oil/water separators (DOWS), has been developed to reduce the cost of handling produced water. DOWS separate oil and gas from produced water at the bottom of the well and reinject some of the produced water into another formation or another horizon within the same formation, while the oil and gas are pumped to the surface. Since much of the produced water is not pumped to the surface, treated, and pumped from the surface back into a deep formation, the cost of handling produced water is greatly reduced. When DOWS are used, additional oil may be recovered as well. In cases where surface processing or disposal capacity is a limiting factor for further production within a field, the use of DOWS to dispose of some of the produced water can allow additional production within that field. Simultaneous injection using DOWS minimizes the opportunity for contamination of underground sources of drinking water (USDWs) through leaks in tubing and casing during the injection process. This report uses the acronym 'DOWS' although the technology may also be referred to as DHOWS or as dual injection and lifting systems (DIALS). Simultaneous injection using DOWS has the potential to profoundly influence the domestic oil industry. The technology has been shown to work in limited oil field applications in the United States and Canada. Several technical papers describing DOWS have been presented at oil and gas industry conferences, but for the most part, the information on the DOWS technology has not been widely transferred to operators, particularly to small or medium-sized independent U.S. companies. One of the missions of the U.S. Department of Energy's (DOE's) National Petroleum Technology Office (NPTO) is to assess the feasibility of promising oil and gas technologies that offer improved operating performance, reduced operating costs, or greater environmental protection. To further this mission, the NPTO provided funding to a partnership of three organizations a DOE national laboratory (Argonne National Laboratory), a private-sector consulting firm (CH2M-Hill), and a state government agency (Nebraska Oil and Gas Conservation Commission) to assess the feasibility of DOWS. The purpose of this report is to provide general information to the industry on DOWS by describing the existing uses of simultaneous injection, summarizing the regulatory implications of simultaneous injection, and assessing the potential future uses of the technology. Chapter 2 provides a more detailed description of the two major types of DOWS. Chapter 3 summarizes the existing U.S. and Canadian installations of DOWS equipment, to the extent that operators have been willing to share their data. Data are provided on the location and geology of existing installations, production information before and after installation of the DOWS, and costs. Chapter 4 provides an overview of DOWS-specific regulatory requirements imposed by some state agencies and discusses the regulatory implications of handling produced water downhole, rather than pumping it to the surface and reinjecting it. Findings and conclusions are presented in Chapter 5 and a list of the references cited in the report is provided in Chapter 6. Appendix A presents detailed data on DOWS installations. This report presents the findings of Phase 1 of the simultaneous injection project, the feasibility assessment. Another activity of the Phase 1 investigation is to design a study plan for Phase 2 of the project, field pilot studies. The Phase 2 study plan is being developed separately and is not included in this report.

International Energy Outlook - World Oil Markets  

Gasoline and Diesel Fuel Update (EIA)

World Oil Markets World Oil Markets International Energy Outlook 2004 World Oil Markets In the IEO2004 forecast, OPEC export volumes are expected to more than double while non-OPEC suppliers maintain their edge over OPEC in overall production. Prices are projected to rise gradually through 2025 as the oil resource base is further developed. Throughout most of 2003, crude oil prices remained near the top of the range preferred by producers in the Organization of Petroleum Exporting Countries (OPEC), $22 to $28 per barrel for the OPEC “basket price.” OPEC producers continued to demonstrate disciplined adherence to announced cutbacks in production. Throughout 2003, the upward turn in crude oil prices was brought about by a combination of three factors. First, a general strike against the Chavez regime resulted in a sudden loss of much of Venezuela’s oil exports. Although the other OPEC producers agreed to increase their production capacities to make up for the lost Venezuelan output, the obvious strain on worldwide spare capacity kept prices high. Second, price volatility was exacerbated by internal conflict in Nigeria. Third, prospects for a return to normalcy in the Iraqi oil sector remained uncertain as residual post-war turmoil continued in Iraq.

Oil production by Candida curvata and extraction, composition and properties of the oil  

Science Conference Proceedings (OSTI)

A strain of the yeast C. curvata was grown in cheese whey permeate under conditions that allowed for oil production. The N-C ratio of the fermentation medium influenced the amount of oil produced. Concentrated permeate could be used as a substrate, but the efficiency of conversion to oil was reduced. The yeast grew well and produced oil in several different types of whey and milk permeates and also in nonsterile systems. The lipid of C. curvata amounted to approximately 50% of its dry weight and could be extracted by sequential treatment with ethanol, hexane, and benzene. The extraction with benzene was necessary for good yields even though nearly all the material extracted with benzene was soluble in hexane. The lipid was 80-90% triglyceride, contained little free fatty acid, and could be degummed by traditional methods. The triglyceride was 30.4% palmitic, 0.84% palmitoleic acid, 11.4% stearic, 51.0% oleic, 6.2% linoleic, and 0.4% linolenic acid. The saturated acyl groups were almost completely on the sn-1 and 3 positions of the glycerol. The oil melting point was -10 to 22 degrees. No tocopherol was detected and the oil oxidized at a rate similar to that for soybean oil at 55 degrees. The oil contained a variety of linear hydrocarbons and 4 sterols. The polar lipids include phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidic acid.

SRC Residual fuel oils  

DOE Patents (OSTI)

Coal solids (SRC) and distillate oils are combined to afford single-phase blends of residual oils which have utility as fuel oils substitutes. The components are combined on the basis of their respective polarities, that is, on the basis of their heteroatom content, to assure complete solubilization of SRC. The resulting composition is a fuel oil blend which retains its stability and homogeneity over the long term.

Acidity of biomass fast pyrolysis bio-oils  

Science Conference Proceedings (OSTI)

The use of the TAN method for measuring the acidity of biomass fast pyrolysis bio-oil was evaluated. Suggestions for carrying out the analysis have been made. The TAN method by ASTM D664 or D3339 can be used for measuring the acidity of fast pyrolysis bio-oils and their hydrotreating products. The main difference between the methods is that ASTM D664 is specified for higher TAN values than ASTM D3339. Special focus should be placed on the interpretation of the TAN curves because they differ significantly from those of mineral oils. The curve for bio-oils is so gentle that the automatic detection may not observe the end point properly and derivatization should be used. The acidity of fast pyrolysis bio-oils is mainly derived (60-70%) from volatile acids. Other groups of compounds in fast pyrolysis bio-oils that influence acidity include phenolics, fatty and resin acids, and hydroxy acids.

Utah Heavy Oil Program  

Science Conference Proceedings (OSTI)

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

Genotypic and environmental factors influencing flesh color, carotene content, total carotenoids, total phenolics and antioxidant activity in potato (Solanum tuberosum L.)  

E-Print Network (OSTI)

The influence of variety and location on flesh color, pigment content and total carotenoid content was studied using Texas and Colorado grown tubers from ten yellow flesh and two white flesh potato varieties. Antioxidant activity and total phenolics of two yellow flesh and two white flesh potato varieties were also determined. Flesh color was determined using a Hunter Colorimeter. Significant differences were found between the same variety grown in both locations for L* value, chroma, and hue. Texas grown tubers were lighter and redder than Colorado grown tubers, which were more yellow. Colorado tubers were lighter in the center than Texas tubers. Carotene and total carotenoid content of the same potato varieties grown in Texas and Colorado were determined, using BPLC and spectrophotometric techniques. Significant differences were found between the same variety grown in both locations for lutein, zeaxanthin, and total carotenoid content. Lutein and total carotenoids were greater in Colorado grown tubers, while zeaxanthin was greater in tubers grown in Texas. Data from the Hunter calorimeter, BPLC, and spectrophotometer were highly correlated, indicating that either of the three instruments can be used to determine flesh color, carotene and total carotenoid content. Varieties differed in antioxidant activity and total phenolic content. Granola had the highest antioxidant activity and Russet Norkotah the highest total phenolic content, while Yukon Gold had the lowest antioxidant activity and total phenolic content. Differences were slight among tuber parts in antioxidant activity, but they were significantly different in total phenolic content. Skin tissue had the highest antioxidant activity and total phenolic content. These differences in flesh color, carotene content, and total carotenoids were controlled genetically but were influenced by environment.

WETTING BEHAVIOR OF SELECTED CRUDE OIL/BRINE/ROCK SYSTEMS  

Science Conference Proceedings (OSTI)

The effect of aging and displacement temperatures, and brine and oil composition on wettability and the recovery of crude oil by spontaneous imbibition and waterflooding has been investigated. This study is based on displacement tests in Berea Sandstone using three distinctly different crude oils and three reservoir brines. Brine concentration was varied by changing the concentration of total dissolved solids of the synthetic brine in proportion to give brine of twice, one tenth, and one hundredth of the reservoir brine concentration. Aging and displacement temperatures were varied independently. For all crude oils, water-wetness and oil recovery increased with increase in displacement temperature. Tests on the effect of brine concentration showed that salinity of the connate and invading brines can have a major influence on wettability and oil recovery at reservoir temperature. Oil recovery increased over that for the reservoir brine with dilution of both the initial (connate) and invading brine or dilution of either. Removal of light components from the crude oil resulted in increased water-wetness. Addition of alkanes to the crude oil reduced the water-wetness, and increased oil recovery. Relationships between waterflood recovery and wettability are summarized.

The depth of the oil/brine interface and crude oil leaks in SPR caverns  

Science Conference Proceedings (OSTI)

Monitoring wellhead pressure evolution is the best method of detecting crude oil leaks in SPR caverns while oil/brine interface depth measurements provide additional insight. However, to fully utilize the information provided by these interface depth measurements, a thorough understanding of how the interface movement corresponds to cavern phenomena, such as salt creep, crude oil leakage, and temperature equilibration, as well as to wellhead pressure, is required. The time evolution of the oil/brine interface depth is a function of several opposing factors. Cavern closure due to salt creep and crude oil leakage, if present, move the interface upward. Brine removal and temperature equilibration of the oil/brine system move the interface downward. Therefore, the relative magnitudes of these factors determine the net direction of interface movement. Using a mass balance on the cavern fluids, coupled with a simplified salt creep model for closure in SPR caverns, the movement of the oil/brine interface has been predicted for varying cavern configurations, including both right-cylindrical and carrot-shaped caverns. Three different cavern depths and operating pressures have been investigated. In addition, the caverns were investigated at four different points in time, allowing for varying extents of temperature equilibration. Time dependent interface depth changes of a few inches to a few feet were found to be characteristic of the range of cases studied. 5 refs, 19 figs., 1 tab.

Oil shale commercialization study  

SciTech Connect

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

HEAVY AND THERMAL OIL RECOVERY PRODUCTION MECHANISMS  

SciTech Connect

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

Crude Oil Analysis Database  

DOE Data Explorer (OSTI)

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

Ames/Salmonella mutagenicity assay of natural and synthetic crude oils including a Fischer-Retorted Estonian shale oil  

DOE Green Energy (OSTI)

DMSO extracts of a variety of natural and synthetic crude oils were tested for genotoxic activity in the Ames/Salmonella bioassay. Both mutagenic and cytotoxic potentials are cited. Natural crude oils and their refined products and upgraded synfuels are less mutagenic than parent crude shale oils which in turn are less mutagenic than the coal derived distillate blend sample, SRC II. However, this order is not true for cytotoxicity induced by these oil samples; therefore, caution must be exercised in the assessment of their mutagenic potential without consideration of other influential factors including cytotoxicity.

The outlook for US oil dependence  

SciTech Connect

Market share OPEC lost in defending higher prices from 1979-1985 is being steadily regained and is projected to exceed 50% by 2000. World oil markets are likely to be as vulnerable to monopoly influence as they were 20 years ago, as OPEC regains lost market share. The U.S. economy appears to be as exposed as it was in the early 1970s to losses from monopoly oil pricing. A simulated 2-year supply reduction in 2005-6 boosts OPEC revenues by roughly half a trillion dollars and costs the U.S. economy an approximately equal amount. The Strategic Petroleum Reserve appears to be of little benefit against such a determined, multi-year supply curtailment either in reducing OPEC revenues or protecting the U.S. economy. Increasing the price elasticity of oil demand and supply in the U.S. and the rest of the world, however, would be an effective strategy.

Costs of U.S. Oil Dependence: 2005 Update  

SciTech Connect

For thirty years, dependence on oil has been a significant problem for the United States. Oil dependence is not simply a matter of how much oil we import. It is a syndrome, a combination of the vulnerability of the U.S. economy to higher oil prices and oil price shocks and a concentration of world oil supplies in a small group of oil producing states that are willing and able to use their market power to influence world oil prices. Although there are vitally important political and military dimensions to the oil dependence problem, this report focuses on its direct economic costs. These costs are the transfer of wealth from the United States to oil producing countries, the loss of economic potential due to oil prices elevated above competitive market levels, and disruption costs caused by sudden and large oil price movements. Several enhancements have been made to methods used in past studies to estimate these costs, and estimates of key parameters have been updated based on the most recent literature. It is estimated that oil dependence has cost the U.S. economy $3.6 trillion (constant 2000 dollars) since 1970, with the bulk of the losses occurring between 1979 and 1986. However, if oil prices in 2005 average $35-$45/bbl, as recently predicted by the U.S. Energy Information Administration, oil dependence costs in 2005 will be in the range of $150-$250 billion. Costs are relatively evenly divided between the three components. A sensitivity analysis reflecting uncertainty about all the key parameters required to estimate oil dependence costs suggests that a reasonable range of uncertainty for the total costs of U.S. oil dependence over the past 30 years is $2-$6 trillion (constant 2000 dollars). Reckoned in terms of present value using a discount rate of 4.5%, the costs of U.S. oil dependence since 1970 are $8 trillion, with a reasonable range of uncertainty of $5 to $13 trillion.

Review and analysis of oil shale technologies. Volume II. True in situ technology  

SciTech Connect

This volume is a technical review and economic analysis of current true in-situ shale technology. Three techniques involving different fracturing methods are compared. Key variables include air compression, drilling depth, drill hole diameter and pattern geometry, shale grade, shale bed thickness, and explosives requirements. Variables, process systems, and process steps defined for each fracturing technique are scaled up to a 64,000-bbl/day facility and costed to provide a basis for evaluating relative economic feasibility. Capital investment, capital depreciation, annual operating, and crude shale oil costs are estimated and compared. The economic evaluation reveals that the choice of fracturing technique does not have any significant effect on the crude oil shale prices estimated for the scaled-up facilities. The costs per barrel vary only about 10%, with the lowest being the facility using the wellbore springing-explosive technique at $19 and the highest being the facility using the underreaming-explosive technique at $21. From a technical standpoint, the combination of hydraulic fracturing and explosive rubblization has the best potential for improvement. A major finding in this evaluation is that high costs associated with compression of the injection gas and drilling strongly influence process economics and, subsequently, crude oil selling prices for all techniques. The actual amount of oil recovered or extracted from the shale is also a major economic factor. The study concludes that the logistics of a commercial operation and the inability to create adequate permeability and surface area by any of the three fracturing techniques evaluated appear to be limiting factors, and that current technology has little potential for technical or economic success. 25 tables, 17 figures.

HEAVY AND THERMAL OIL RECOVERY PRODUCTION MECHANISMS  

Science Conference Proceedings (OSTI)

This technical progress report describes work performed from January 1 through March 31, 2003 for the project ''Heavy and Thermal Oil Recovery Production Mechanisms,'' DE-FC26-00BC15311. In this project, a broad spectrum of research is undertaken related to thermal and heavy-oil recovery. The research tools and techniques span from pore-level imaging of multiphase fluid flow to definition of reservoir-scale features through streamline-based history matching techniques. During this period, previous analysis of experimental data regarding multidimensional imbibition to obtain shape factors appropriate for dual-porosity simulation was verified by comparison among analytic, dual-porosity simulation, and fine-grid simulation. We continued to study the mechanisms by which oil is produced from fractured porous media at high pressure and high temperature. Temperature has a beneficial effect on recovery and reduces residual oil saturation. A new experiment was conducted on diatomite core. Significantly, we show that elevated temperature induces fines release in sandstone cores and this behavior may be linked to wettability. Our work in the area of primary production of heavy oil continues with field cores and crude oil. On the topic of reservoir definition, work continued on developing techniques that integrate production history into reservoir models using streamline-based properties.

Oil Dependence: The Value of R{ampersand}D  

SciTech Connect

Over the past quarter century the United States` dependence on oil has cost its economy on the order of $5 trillion. Oil dependence is defined as economically significant consumption of oil, given price inelastic demand in the short and long run and given the ability of the OPEC cartel to use market power to influence oil prices. Although oil prices have been lower and more stable over the past decade, OPEC still holds the majority of the world`s conventional oil resources according to the best available estimates. OPEC`s share of the world oil market is likely to grow significantly in the future,restoring much if not all of their former market power. Other than market share, the key determinants of OPEC`s market power are the long and short run price elasticities of world oil demand and supply. These elasticities depend critically on the technologies of oil supply and demand, especially the technology of energy use in transportation. Research and development can change these elasticities in fundamental ways, and given the nature of the problem,the government has an important role to play in supporting such research.

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

Science Conference Proceedings (OSTI)

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

HEAVY AND THERMAL OIL RECOVERY PRODUCTION MECHANISMS  

Science Conference Proceedings (OSTI)

This technical progress report describes work performed from October 1 through December 31, 2002 , for the project ''Heavy and Thermal Oil Recovery Production Mechanisms.'' In this project, a broad spectrum of research is undertaken related to thermal and heavy-oil recovery. The research tools and techniques used are varied and span from pore-level imaging of multiphase fluid flow to definition of reservoir-scale features through streamline-based history-matching techniques. During this period, experimental data regarding multidimensional imbibition was analyzed to obtain shape factors appropriate for dual-porosity simulation. It is shown that the usual assumption of constant, time-independent shape factors is incorrect. In other work, we continued to study the mechanisms by which oil is produced from fractured media at high pressure and high temperature. High temperature significantly increased the apparent wettability and affected water relative permeability of cores used in previous experiments. A phenomenological and mechanistic cause for this behavior is sought. Our work in the area of primary production of heavy oil continues with field cores and crude oil. On the topic of reservoir definition, work continued on developing techniques that integrate production history into reservoir models using streamline-based properties.

Oil, war, and American security: the search for a national policy on foreign oil, 1941-1947  

Science Conference Proceedings (OSTI)

This book is concerned with the search for a national policy on foreign oil from 1941 to 1947. World War II saw an attempt to develop a national policy on foreign oil. The United States did not have a diplomatic post in Arabia until 1942, though for some time Ibn Saud's nearly bankrupt kingdom had been partly supported by the British government and American oil companies. In 1941, the United States established an office in the State Department to deal with oil policy; it was headed by an oil executive whose company continued to pay him nearly four times his federal salary. Characteristically Roosevelt played off subordinates, Harold Ickes and Cordell Hull, against one another, and the impetus toward a policy was due in part to their jockeying for control. Rivalry with England, another major factor, led to an Anglo-American oil agreement, but this pact was not ratified by the Senate. The style of the book is narrative. (DP)

Why solar oil shale retorting produces more oil  

DOE Green Energy (OSTI)

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

Oil, turmoil, and Islam in the Middle East  

SciTech Connect

The turmoil and strife of the Middle East raises serious questions about the security of the world's oil supply. The author argues that OPEC and OAPEC can no longer afford to impose indiscriminate price increases on the marketplace because they hurt not only themselves but oil poor Third World nations as well. The author analyzes the importance of Middle Eastern oil in world politics. He emphasizes that any consideration of the forces influencing development in the Middle East should take Islamic tradition into account. Each chapter is organized around a current Middle Eastern problem: oil politics in relation to international energy needs; the ramifications of the new oil wealth and power of the Middle East; The Iran-Iraq War; Muslim insurgency in Afghanistan; The Arab-Israel conflict; turmoil in Lebanon; Palestinian nationalism; and the Middle East as a superpower.

High pressure pair distribution function studies of Green River oil shale.  

Science Conference Proceedings (OSTI)

The compression behavior of a silicate-rich oil shale from the Green River formation in the pressure range 0.0-2.4 GPa was studied using in situ high pressure X-ray pair distribution function (PDF) measurements for the sample contained within a Paris-Edinburgh cell. The real-space local structural information in the PDF, G(r), was used to evaluate the compressibility of the oil shale. Specifically, the pressure-induced reduction in the medium- to long-range atom distances ({approx}6-20 {angstrom}) yielded an average sample compressibility corresponding to a bulk modulus of ca. 61-67 GPa. A structural model consisting of a three phase mixture of the principal crystalline oil shale components (quartz, albite and Illite) provided a good fit to the ambient pressure PDF data (R {approx} 30.7%). Indeed the features in the PDF beyond {approx} {angstrom}, were similarly well fit by a single phase model of the highest symmetry, highly crystalline quartz component. The factors influencing the observed compression behavior are discussed.

Refining of shale oil  

DOE Green Energy (OSTI)

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

Heavy crude oil recovery  

SciTech Connect

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

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

E-Print Network (OSTI)

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

Corrosivity Of Pyrolysis Oils  

SciTech Connect

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

Oil shale data book  

SciTech Connect

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

Oil gas J report. Mexico. [Mexico  

SciTech Connect

Mexico's oil industry continues its rise, but it has not yet been able to ignite sluggish sectors of the economy nor bring national prosperity. Petroleos Mexicanos (PEMEX) has accomplished about everything an oil company can do. Total claimed proved reserves of oil, gas liquids, and gas (oil equivalent) climbed 12 billion bbl to 72,000 billion bbl in 1981. They could hit 80 billion bbl by year-end 1982. Production (oil, gas, and gas liquids) rose by half a million barrels per day to 3,125,000 bpd. With the proper market and mandate, PEMEX could top that in 1982.

Oil and OPEC: An analysis of United States oil dependency and the changing face of OPEC. Study project  

SciTech Connect

Throughout the twentieth century, major oil companies have been the object of intense scrutiny, suspicion, and mistrust. In their heyday before World War II, they controlled over 90 percent of the world oil production. As the Second World War was coming to an end, it became clear that the United States would not longer continue to be a major exporter of oil and that the Middle East would be called upon to meet the rising needs of the world. In the 1960s and 1970s, the Middle Eastern oil-producing countries (OPEC) wrested more power from the major Western companies either through sweeping new agreements or through nationalization movements. Oil power catapulted these Third World countries into the international arena and into positions of great wealth and influence. Just as oil has enabled nations to accumulate wealth and power, it has also proved that it is a prize that can be overvalued and can lead to a country's demise. Oil imports are impairing or threaten to impair the national security of the United States. The U.S. finds itself more vulnerable to political or economic blackmail because of its reliance on foreign oil supplies.

Market assessment for shale oil  

DOE Green Energy (OSTI)

This study identified several key issues on the cost, timeliness, and ease with which shale oil can be introduced into the United States' refining system. The capacity of the existing refining industry to process raw shale oil is limited by the availability of surplus hydrogen for severe hydrotreating. The existing crude oil pipeline system will encounter difficulties in handling raw shale oil's high viscosity, pour point, and contaminant levels. The cost of processing raw shale oil as an alternate to petroleum crude oil is extremely variable and primarily dependent upon the percentage of shale oil run in the refinery, as well as the availability of excess hydrogen. A large fraction of any shale oil which is produced will be refined by the major oil companies who participate in the shale oil projects and who do not anticipate problems in processing the shale oil in their refineries. Shale oil produced for sale to independent refiners will initially be sold as boiler fuel. A federal shale oil storage program might be feasible to supplement the Strategic Petroleum Reserve. Based on refinery configurations, hydrogen supply, transportation systems, and crude availability, eleven refineries in Petroleum Administration for Defense Districts (PADDs) 2A and 2B have been identified as potential processors of shale oil. Based on refining technology and projected product demands to the year 2000, shale oil will be best suited to the production of diesel fuel and jet fuel. Tests of raw shale oil in boilers are needed to demonstrate nitrogen oxide emissions control.

Coastal wetlands are particularly susceptible to oil contamination because they are composed largely of fine-grained sediments, which have a high capacity to adsorb oil and associated metals. Microbial activities may be enhanced by an increase in amounts of organic matter and subsequently influence the biogeochemical cycling of trace metals. This research assesses the levels of oil and trace metals, along with associated biogeochemical changes, in six coastal marshes in Mississippi and Louisiana.

Factors influencing antioxidant phytochemical stability of teas  

E-Print Network (OSTI)

Tea is second only to water as the most consumed beverage in the world due to its health-promoting benefits and characteristic flavor. Even though many botanical teas such as yaupon holly (Ilex vomitoria) and mamaki (Pipturus albidus) are currently available in the tea market, only limited information is available on their polyphenolic contents containing diverse biological activities. Identification of phenolic compounds was performed using advanced analytical technique of mass spectrometry to provide polyphenolic profile of teas. To present fundamental information of phytochemical stability during tea storage, studies to determine the impacts of tea processing, different packaging materials, and various storage conditions on the phytochemical stability were conducted. Ascorbic acid addition and lowering pH successfully decreased the reduction of phenolic compounds by reducing the rate of oxidative degradation while tea pasteurization accelerated oxidative degradation. Glass bottles were most effective to retain higher concentration of polyphenolics. Tea polyphenolics at lower temperature (3 °C) without light exposure were higher retained in each tea. Tea cream, the complex formed by interaction between polyphenolics, caffeine, protein, and metal ions, is highly undesirable in tea industry since it causes haziness and cloudiness in tea infusion as well as deteriorates sensorial properties. Only limited information is available on tea creaming in non-fermented type teas such as green tea, yaupon holly, and mamaki even though many tea creaming compounds are present in these teas. Therefore, studies were conducted to determine the degree of contribution of the tea creaming compounds to tea creaming and to develop novel chemical methods to minimize tea creaming without detrimental effects. Methods applied in the present study defined that hydrophobic interaction was the driving force make tea cream insoluble in the solution. Results obtained by present studies provided fundamental and practical information to the tea industry in terms of phytochemical stability and suggested storage stability of phytochemicals should be considered during processing and storage, since it could be better retained or improved by applying appropriate methods.

Futures oil market outlook  

Science Conference Proceedings (OSTI)

We expect the broader expansion of global economic activity in 1995 to more than offset the anticipated slowdown in the US economic growth. This should result in worldwide oil demand growth in excess of 1 million barrels per day and firmer oil prices. This comes on the heels of nearly identical growth in 1994 and should be followed by an even larger increase in 1996. This year`s demand growth comes against a backdrop of flat OPEC production and an increase in non-OPEC supplies that will fall short of the expected increase in consumption. Some degree of political upheaval in at least a half dozen important oil exporting nations could also have implication for crude supplies. One major wildcard that remains for global oil markets is the status of the United Nations` sanctions on Iraqi exports and the timing of when these sanctions are to be eased or lifted completely.

The effective approach for predicting viscosity of saturated and undersaturated reservoir oil  

E-Print Network (OSTI)

Predicting reservoir oil viscosity with numerical correlation equations using field-measured variables is widely used in the petroleum industry. Most published correlation equations, however, have never profoundly realized the genuine relationship between the reservoir oil viscosity and other field-measured parameters. Using the proposed systematic strategy is an effective solution for achieving a high performance correlation equation of reservoir oil viscosity. The proposed strategy begins with creating a large database of pressure-volumetemperature (PVT) reports and screening all possible erroneous data. The relationship between the oil viscosity and other field-measured parameters is intensively analyzed by using theoretical and empirical approaches to determine the influential parameters for correlating reservoir oil viscosity equations. The alternating conditional expectation (ACE) algorithm is applied for correlating saturated and undersaturated oil viscosity equations. The precision of field-measured PVT data is inspected by a data reconciliation technique in order to clarify the correctness of oil viscosity correlations. Finally, the performance of the proposed oil viscosity correlation equations is represented in terms of statistical error analysis functions. The result of this study shows that reservoir oil density turns out to be the most effective parameter for correlating both saturated and undersaturated reservoir oil viscosity equations. Expected errors in laboratory-measured oil viscosity are the main factors that degrade the efficiency of oil viscosity correlation equations. The proposed correlation equations provide a reasonable estimate of reservoir oil viscosity; and their superior performance is more reliable than that of published correlation equations at any reservoir conditions.

Oil recovery process  

Science Conference Proceedings (OSTI)

An on-site, in-line process and system is claimed for recovering oil from oil-bearing subterranean formations which involves the production, modification, dilution and injection of a polymer solution, preferably consisting essentially of an aqueous solution of a partially hydrolyzed polyacrylamide, having injectivity and mobility properties capable of meeting the specific permeability requirements of substantially any subterranean formation to be achieved. The polymer solutions prepared by the process and system can be used as drive fluids for displacing oil (secondary polymer flood) in an oil-bearing formation, as mobility buffers to follow micellar dispersion floods in the conjoint presence of chemical reagents in other chemical floods (e.g., surfactant, caustic, etc.), or they can follow a water flood. The solutions can also be used to promote pipelining of high viscosity crude oil. Irrespective of the use to which the solutions are put, the process and system enable the polymer solutions to be customized, or tailor-made, so to speak, to meet the performance demands of the environment in which they are to be used, whether it be an oil-bearing formation or a pipeline.

Chemically enhanced oil recovery  

Science Conference Proceedings (OSTI)

Yet when conducted according to present state of the art, chemical flooding (i.e., micellar/polymer flooding, surfactant/polymer flooding, surfactant flooding) can mobilize more residual crude oil than any other method of enhanced oil recovery. It also is one of the most expensive methods of enhanced oil recovery. This contribution will describe some of the technology that comprises the state of the art technology that must be adhered to if a chemical flood is to be successful. Although some of the efforts to reduce cost and other points are discussed, the principle focus is on technical considerations in designing a good chemical flooding system. The term chemical flooding is restricted here to methods of enhanced oil recovery that employs a surfactant, either injected into the oil reservoir or generated in situ, primarily to reduce oil-water interfacial tension. Hence, polymer-water floods for mobility or profile control, steam foams, and carbon dioxide foams are excluded. Some polymer considerations are mentioned because they apply to providing mobility control for chemical flooding systems.

Process for preparing lubricating oil from used waste lubricating oil  

DOE Patents (OSTI)

A re-refining process is described by which high-quality finished lubricating oils are prepared from used waste lubricating and crankcase oils. The used oils are stripped of water and low-boiling contaminants by vacuum distillation and then dissolved in a solvent of 1-butanol, 2-propanol and methylethyl ketone, which precipitates a sludge containing most of the solid and liquid contaminants, unspent additives, and oxidation products present in the used oil. After separating the purified oil-solvent mixture from the sludge and recovering the solvent for recycling, the purified oil is preferably fractional vacuum-distilled, forming lubricating oil distillate fractions which are then decolorized and deodorized to prepare blending stocks. The blending stocks are blended to obtain a lubricating oil base of appropriate viscosity before being mixed with an appropriate additive package to form the finished lubricating oil product.

Kinetics of decomposition of Colorado oil shale. I. Oil generation. [Use of isothermal and nonisothermal methods  

DOE Green Energy (OSTI)

Isothermal and nonisothermal methods were used to investigate the kinetics of oil generation during decomposition of 91.7 l/tonne (22-gal/ton) Colorado oil shale. The average of the results from these two methods gives an activation energy of 52.0 kcal/mole and a frequency factor of 3 x 10/sup 13/s/sup -1/. The process is found to be first order to within experimental error. These results compare favorably with data reported in the literature. The reliability and ease of carrying out nonisothermal kinetic experiments to study solid decomposition reactions is demonstrated. Moreover, nonisothermal experiments more accurately simulate actual in situ processing conditions.

DOE Green Energy (OSTI)

Results from spectroscopic investigations are presented that demonstrate the effect of oil cracking on shale oil composition. Techniques used include infrared spectroscopy, capillary column gas chromatography/mass spectroscopy and /sup 13/C nuclear magnetic resonance. We show that cracking causes an increase in aromatic and alkene content of the oil. We compare our results for oils prepared in the laboratory with oils prepared in the TOSCO-II semi-works and in modified and true-in-situ combustion retorts. We demonstrate that the napthalene/2-methyl-naphthalene ratio is a good indicator of cracking conditions in an oil shale retort.

World oil: Market or mayhem  

E-Print Network (OSTI)

The world oil market is regarded by many as a puzzle. Why are oil prices so volatile? What is OPEC and what does OPEC do? Where are oil prices headed in the long run? Is “peak oil ” a genuine concern? Why did oil prices spike in the summer of 2008, and what role did speculators play? Any attempt to answer these questions must be informed and disciplined by economics. Such is the purpose of this essay: to illuminate recent developments in the world oil market from the perspective of economic theory.

Shale oil cracking. 1. Kinetics  

DOE Green Energy (OSTI)

Experiments were conducted to determine kinetics for thermal cracking of shale oil vapor over shale. Cracking temperatures of 504 to 610/sup 0/C and residence times of 2 to 11 seconds were used. A first-order Arrhenius rate expression and stoichiometry were obtained. Also observed were changes in the oil quality. Cracking decreased the H/C ratio, increased the nitrogen content, and decreased the pour point of the oil. Gas-phase oil cracking is contrasted to liquid-phase oil coking as a loss mechanism in oil-shale retorting.

Methods for Assessing the Impact of Fog Oil Smoke on Availability, Palatability, & Food Quality of Relevant Life Stages of Insects for Threatened and Endangered Species  

SciTech Connect

A methodology for quantifying population dynamics and food source value of insect fauna in areas subjected to fog oil smoke was developed. Our approach employed an environmentally controlled re-circulating wind tunnel outfitted with a high-heat vaporization and re-condensation fog oil generator that has been shown to produce aerosols of comparable chemistry and droplet-size distribution as those of field releases of the smoke. This method provides reproducible exposures of insects under realistic climatic and environmental conditions to fog oil aerosols that duplicate chemical and droplet-size characteristics of field releases of the smoke. The responses measured take into account reduction in food sources due to death and to changes in availability of relevant life stages of insects that form the prey base for the listed Threatened and Endangered Species. The influence of key environmental factors, wind speed and canopy structure on these responses were characterized. Data generated using this method was used to develop response functions related to particle size, concentration, wind speed, and canopy structure that will allow military personnel to assess and manage impacts to endangered species from fog oil smoke used in military training.

Abandoned Texas oil fields  

SciTech Connect

Data for Texas abandoned oil fields were primarily derived from two sources: (1) Texas Railroad Commission (TRRC), and (2) Dwight's ENERGYDATA. For purposes of this report, abandoned oil fields are defined as those fields that had no production during 1977. The TRRC OILMASTER computer tapes were used to identify these abandoned oil fields. The tapes also provided data on formation depth, gravity of oil production, location (both district and county), discovery date, and the cumulative production of the field since its discovery. In all, the computer tapes identified 9211 abandoned fields, most of which had less than 250,000 barrel cumulative production. This report focuses on the 676 abandoned onshore Texas oil fields that had cumulative production of over 250,000 barrels. The Dwight's ENERGYDATA computer tapes provided production histories for approximately two-thirds of the larger fields abandoned in 1966 and thereafter. Fields which ceased production prior to 1966 will show no production history nor abandonment date in this report. The Department of Energy hopes the general availability of these data will catalyze the private sector recovery of this unproduced resource.

Gundrilling Oil Evaluation to Find a Replacement for 50-50  

SciTech Connect

In 2006 the gundrilling oil used at Honeywell FM&T (Federal Manufacturing and Technology) was known as 50-50. This name was selected because the oil is a mixture of two machining oils, Milpro 634 and Pennex N47. Unfortunately, Honeywell FM&T was notified that one component, Pennex N47, would be discontinued by the manufacturer. At this point the Honeywell FM&T team decided to select a single oil to eliminate mixing and procurement of two products. In addition, the team also wanted to select new oil with lower viscosity than the 50-50 mixture. Lower (than 50-50) viscosity oil was recommended by Nagel the manufacturer of the new TBT gundrilling machines. To this end Honeywell FM&T evaluated seven cutting oils in order to select a substitute that would achieve acceptable gundrilling results. This work resulted in the selection of Castrol Ilocut 334 based on cutting performance and human factors. The Castrol oil can easily achieve up to 8 holes per drill at a feed rate 30% greater than that achieved by the 50-50 oil. Once design agency approval is received, this oil will be installed as the drilling oil for all FM&T stems. This oil will also be used for other reservoir machining operations where appropriate.

Characterization of oil and gas reservoir heterogeneity  

SciTech Connect

Research described In this report addresses the internal architecture of two specific reservoir types: restricted-platform carbonates and fluvial-deltaic sandstones. Together, these two reservoir types contain more than two-thirds of the unrecovered mobile oil remaining ill Texas. The approach followed in this study was to develop a strong understanding of the styles of heterogeneity of these reservoir types based on a detailed outcrop description and a translation of these findings into optimized recovery strategies in select subsurface analogs. Research targeted Grayburg Formation restricted-platform carbonate outcrops along the Algerita Escarpment and In Stone Canyon In southeastern New Mexico and Ferron deltaic sandstones in central Utah as analogs for the North Foster (Grayburg) and Lake Creek (Wilcox) units, respectively. In both settings, sequence-stratigraphic style profoundly influenced between-well architectural fabric and permeability structure. It is concluded that reservoirs of different depositional origins can therefore be categorized Into a heterogeneity matrix'' based on varying intensity of vertical and lateral heterogeneity. The utility of the matrix is that it allows prediction of the nature and location of remaining mobile oil. Highly stratified reservoirs such as the Grayburg, for example, will contain a large proportion of vertically bypassed oil; thus, an appropriate recovery strategy will be waterflood optimization and profile modification. Laterally heterogeneous reservoirs such as deltaic distributary systems would benefit from targeted infill drilling (possibly with horizontal wells) and improved areal sweep efficiency. Potential for advanced recovery of remaining mobile oil through heterogeneity-based advanced secondary recovery strategies In Texas is projected to be an Incremental 16 Bbbl. In the Lower 48 States this target may be as much as 45 Bbbl at low to moderate oil prices over the near- to mid-term.

Political Constraints on Government Cartelization: The Case of Oil Production Regulation in Texas and Saudi Arabia by  

E-Print Network (OSTI)

We examine government cartelization efforts in crude oil production. Texas and Saudi Arabia are alleged to act as swing producers to maintain the interstate (1933-1972) and OPEC (1973 on) oil cartels respectively. We analyze the political constraints that affected the ability of Texas and Saudi Arabia to act as residual producers within their respective cartels. In the case of Texas, political factors molded individual firm production quotas, advantaging high-cost producers and hence, reducing total cartel net profits. Further, Texas had limited range for adjusting total state production to maintain interstate output at levels consistent with target prices. Saudi Arabia’s role as swing producer within OPEC raises similar questions regarding how cartel output is shared among members, and the extent to which domestic economic and political pressures coming from various member countries may undermine the effectiveness of the cartel. OPEC ‘s coordination problem has been more difficult than that faced by the interstate cartel for a variety of reasons that we explore. Even so, they have not kept the OPEC members in general, and Saudi Arabia in particular, from exerting a strong influence on the level of world oil prices.

Mobility control in oil recovery by chemical flooding: State-of-the-art review: Topical report. [177 references  

Science Conference Proceedings (OSTI)

Mobility control in oil recovery by chemical flooding (polymer, micellar-polymer, and alkaline-polymer) can be achieved through the use of low-concentration water-soluble polymers in water or in chemical slugs. Since the late 1950's, water-soluble polymers have been studied extensively in laboratories by many researchers and widely used in many chemical flooding projects to improve sweep efficiency and increase ultimate oil recovery. Effective use of polymers as mobility control agents requires the understanding of the stability of polymers and their rheological behavior in reservoirs. An overview of the scientific literature on the application of water-soluble polymers in enhanced oil recovery (EOR) is presented. The processes, factors, and mechanisms that influence the stability of polymers and those that cause a reduction in water mobility are discussed. Existing knowledge of polymer flow behavior in porous media, and of surfactant-polymer interactions is reviewed. Also discussed are the case histories of 23 chemical flooding field projects. 177 refs., 6 figs., 5 tabs.

MAJOR OIL PLAYS IN UTAH AND VICINITY  

Science Conference Proceedings (OSTI)

Utah oil fields have produced over 1.2 billion barrels (191 million m{sup 3}). However, the 13.7 million barrels (2.2 million m{sup 3}) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. The Utah Geological Survey believes this trend can be reversed by providing play portfolios for the major oil producing provinces (Paradox Basin, Uinta Basin, and thrust belt) in Utah and adjacent areas in Colorado and Wyoming. Oil plays are geographic areas with petroleum potential caused by favorable combinations of source rock, migration paths, reservoir rock characteristics, and other factors. The play portfolios will include: descriptions and maps of the major oil plays by reservoir; production and reservoir data; case-study field evaluations; summaries of the state-of-the-art drilling, completion, and secondary/tertiary techniques for each play; locations of major oil pipelines; descriptions of reservoir outcrop analogs; and identification and discussion of land use constraints. All play maps, reports, databases, and so forth, produced for the project will be published in interactive, menu-driven digital (web-based and compact disc) and hard-copy formats. This report covers research activities for the third quarter of the first project year (January 1 through March 31, 2003). This work included gathering field data and analyzing best practices in the eastern Uinta Basin, Utah, and the Colorado portion of the Paradox Basin. Best practices used in oil fields of the eastern Uinta Basin consist of conversion of all geophysical well logs into digital form, running small fracture treatments, fingerprinting oil samples from each producing zone, running spinner surveys biannually, mapping each producing zone, and drilling on 80-acre (32 ha) spacing. These practices ensure that induced fractures do not extend vertically out of the intended zone, determine the percentage each zone contributes to the overall production of the well, identify areas that may be by-passed by a waterflood, and prevent rapid water breakthrough. In the eastern Paradox Basin, Colorado, optimal drilling, development, and production practices consist of increasing the mud weight during drilling operations before penetrating the overpressured Desert Creek zone; centralizing treatment facilities; and mixing produced water from pumping oil wells with non-reservoir water and injecting the mixture into the reservoir downdip to reduce salt precipitation, dispose of produced water, and maintain reservoir pressure to create a low-cost waterflood. During this quarter, technology transfer activities consisted of technical presentations to members of the Technical Advisory Board in Colorado and the Colorado Geological Survey. The project home page was updated on the Utah Geological Survey Internet web site.

This chart shows prices through February 28, the most recent EIA data available. The general level of heating oil prices each year is largely a function of crude oil prices, and the price range over the course of the heating season is typically about 10 cents per gallon. Exceptions occur in unusual circumstances, such as very cold weather, large changes in crude oil prices, or supply problems. Heating oil prices for East Coast consumers started this winter at just over $1 per gallon, but rising crude oil prices drove them up nearly 21 cents through mid-January.

Business cycles in oil economies  

SciTech Connect

This study examines the impact of oil price shocks on output fluctuations of several oil-exporting economies. In most studies of business cycles, the role of oil price is ignored; the few studies that use oil price as one of the variables in the system focus on modeling oil-importing economies. The vector autoregression (VAR) technique is used to consider the cases of Norway, Nigeria, and Mexico. Both atheoretical and structural' VARs are estimated to determine the importance of oil price impulses on output variations. The study reports two types of results: variance decomposition and impulse response functions, with particular emphasis on the issues of stationarity and co-integration among the series. The empirical results suggest that shocks to oil price are important in explaining output variations. In most cases, shocks to oil price are shown to explain more than 20% of the forecast variance of output over a 40-quarter horizon.

Market assessment for shale oil  

SciTech Connect

This study identified several key issues on the cost, timeliness, and ease with which shale oil can be introduced into the United States' refining system. The capacity of the existing refining industry to process raw shale oil is limited by the availability of surplus hydrogen for severe hydrotreating. The existing crude oil pipeline system will encounter difficulties in handling raw shale oil's high viscosity, pour point, and contaminant levels. The cost of processing raw shale oil as an alternate to petroleum crude oil is extremely variable and primarily dependent upon the percentage of shale oil run in the refinery, as well as the availability of excess hydrogen. A large fraction of any shale oil which is produced will be refined by the major oil companies who participate in the shale oil projects and who do not anticipate problems in processing the shale oil in their refineries. Shale oil produced for sale to independent refiners will initially be sold as boiler fuel. A federal shale oil storage program might be feasible to supplement the Strategic Petroleum Reserve. Based on refinery configurations, hydrogen supply, transportation systems, and crude availability, eleven refineries in Petroleum Administration for Defense Districts (PADDs) 2A and 2B have been identified as potential processors of shale oil. Based on refining technology and projected product demands to the year 2000, shale oil will be best suited to the production of diesel fuel and jet fuel. Tests of raw shale oil in boilers are needed to demonstrate nitrogen oxide emissions control.

Comparative assessment of the trace-element composition of coals, crude oils, and oil shales  

Science Conference Proceedings (OSTI)

A comparative analysis of the amounts of 42 trace elements in coals, crude oils, and oil and black shales was performed. The degree of concentration of trace elements by caustobioliths and their ashes relative to their abundance in argillaceous rocks and the Earth's crust was calculated. Typomorphic trace elements were distinguished, of which many turned out to be common for the different kinds of caustobioliths in question. The trace elements were classified according to their concentration factors in different caustobioliths. The ash of crude oils is enriched in trace elements (Cs, V, Mo, Cu, Ag, Au, Zn, Hg, Se, Cr, Co, Ni, U) to the greatest extent (concentration factor above 3.5) and that of oil shales is enriched to the least extent (Re, Cs, Hg, Se). The ratios between typomorphic trace elements in general strongly differ from those in the Earth's crust and argillaceous rocks and are not identical in different caustobioliths. Quantitative parameters that make it possible to calculate a change in these ratios on passing from one caustobiolith type to another were proposed and the relative trace-element affinity of different caustobioliths was estimated.

Careful utilization of their own reserves of coal, oil, and gas (Germany, France, Spain) and assigned shares of imports of these resources make up the strategy of economic development of the European countries. The expansion of oil shale utilization is the most topical problem. The experience of mining oil shale deposits in Estonia and Russia, in terms of the practice and the economic results, is reviewed in this article. The room-and-pillar method of underground mining and the open-cut technology of clearing the ground ensure the fertility of a soil. The economics of underground and open pit oil shale mines is analyzed in terms of natural, organizational, and technical factors. These analyses are used in the planning and management of oil shale mining enterprises. The perspectives of the oil shale mining industry of Estonia and the economic expediency of multiproduction are examined. Recommendations and guidelines for future industrial utilization of oil shale are given in the summary.

Future world oil supply and demand-the impact on domestic exploration  

SciTech Connect

Current world oil consumption (demand) of about 68 million B/D will increase to over 81 million B/D in 10 years. World oil production capacity (supply), currently 6-8% over current demand, cannot meet this demand without adequate investments to boost capacity, particularly in the Middle East. Because of low oil prices these investments are not being made. In 10 years the Middle East needs to supply over 50% of the worlds oil; the Far East will by then surpass North America in demand. It is very possible that there will soon be a period of time when the supply/demand balance will be, or will perceived to be failing. This may cause rapid rises in crude oil prices until the balance is again achieved. Crude oil prices are actually quite volatile; the steadiness and abnormally low prices in recent years has been due to several factors that probably won`t be present in the period when the supply/demand situation is seen to be unbalanced. Domestic oil exploration is strongly affected by the price of crude oil and domestic producers should soon benefit by rising oil prices. Exploration will be stimulated, and small incremental amounts of new oil should be economically viable. Oil has been estimated to be only 2% of the total cost of producing all U.S. goods and services-if so, then oil price increase should not create any real problems in the total economic picture. Nevertheless, certain industries and life styles heavily dependent on cheap fuel will have problems, as the days of cheap oil will be gone. Future undiscovered oil in the Earth could be one trillion barrels or more, equal to the amount now considered as proved reserves. There will soon be more of a challenge to find and produce this oil in sufficient quantity and at a competitive cost with other sources of energy. This challenge should keep us busy.

Contamination of the transformer oil of power transformers and shunting reactors by metal-containing colloidal particles  

SciTech Connect

The results of a measurement of the contamination of the oil in 66 transformers by metal-containing colloidal particles, formed as a result of the interaction of the oil with the structural materials (the copper of the windings, the iron of the tank and core etc.), and also the results of measurements of the optical turbidity of the oil in 136 transformers when they were examined at the Power Engineering Research and Development Center Company are presented. Methods of determining the concentration of copper and iron in transformer oil are considered. The limiting values of the optical turbidity factors, the copper and iron content are determined. These can serve as a basis for taking decisions on whether to replace the silica gel of the filters for continuously purifying the oil of power transformers and the shunting reactors in addition to the standardized oil contamination factors, namely, the dielectric loss tangent and the acidity number of the oil.

Membrane degumming of crude vegetable oil  

E-Print Network (OSTI)

Crude vegetable oils contain various minor substances like phospholipids, coloring pigments, and free fatty acids (FFA) that may affect quality of the oil. Reduction of energy costs and waste disposal are major concerns for many oil refiners who are looking for alternative methods to improve conventional refining methods. During the last decade, energy efficient membrane separation technology has evolved dramatically. This thesis reports a study on degumming crude vegetable oil using membrane separation. In the bench-scale study, two membranes were evaluated for their flux and rejection properties. Process parameters including pressure, temperature, feed velocity and volumetric concentration factor were examined. A 99.6% rejection of phospholipids and a flux of 22.4 LMH were achieved at pressure 300 psi, temperature 40'C and feed velocity 220 1/hr using DS-7 membrane, and significant reduction of the coloring pigments was observed as well. In the pilot-scale study, the spiral wound DS-7 membrane was found effective for 100% rejection of phospholipids with a permeate flux of 57.6 LMH. The rejection rates of phospholipids, Mg and Ca were 100%, 99.6% and 54.6%, respectively. Resistance-in-series model of the membrane system was also studied. The membrane resistance, the fouling resistance, and the polarization resistance for the pilotscale system were 0.29, 0.043, and 4.49, respectively. Evaluation on membrane fouling and cleaning showed that flux decreased rapidly during the first several hours and membrane cleaning presented no significant problem. The pilot-scale study confirmed results of the bench-scale system and provides useful data for commercializing membrane refining process in the near future. KEY WORDS: Membrane separation, crude vegetable oil, degumming, phospholipids.

The world oil market and OPEC behavior: The leak-producer price leader model  

SciTech Connect

This is an economic study of the world's oil market in which OPEC plays the central role in determining the oil supply and price. Understanding OPEC's behavior is at the core of understanding the world's oil market. However, oil is a resource belonging to the family of natural resources known as exhaustible. We do not produce oil; we only extract and distribute a fixed amount of the resource over generations. Optimal extraction is a matter of concern to both suppliers and consumers. First, it is shown that using the traditional theory of producers behavior in the conventional commodity markets to explain extractors behavior in exhaustible resource markets is completely wrong. Second, current models of OPEC behavior are reviewed. Third, an alternative model is introduced. Previous authors have not directed their models to give explanations to the peculiar observations in oil market. This model divides the world's oil suppliers into: the free riders (non-OPEC oil producers), the OPEC hawks (a group within OPEC) and the leak-producer price leader (Saudi Arabia). Three factors, namely relatively big oil reserves, no other sources of income, and the avoidance of the so-called backstop technology make Saudi Arabia more interested in lower oil prices than are other oil extractors.

Regional Residential Heating Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

Slide 2 of 11 Notes: One of the first places where consumers are feeling the impact of this winterÂ’s market pressures is in home heating oil prices. This chart shows prices through February 7, the most recent EIA data available. The general level of heating oil prices each year is largely a function of crude oil prices, and the price range over the course of the heating season is typically about 10 cents per gallon. Exceptions occur in unusual circumstances, such as very cold weather, large changes in crude oil prices, or supply problems. Heating oil prices for East Coast consumers started this winter at just over $1 per gallon, but rising crude oil prices drove them up nearly 21 cents per gallon through mid-January. With the continuing upward pressure from crude oil markets, magnified by a regional shortfall of

Measuring Dependence on Imported Oil  

Gasoline and Diesel Fuel Update (EIA)

Dependence on Imported Oil Dependence on Imported Oil by C. William Skinner* U.S. dependence on imported oil** can be measured in at least two ways. The differences hinge largely on whether oil imports are defined as net imports (total imports minus exports) or as total imports. EIA believes that the net-imports definition gives a clearer indication of the fraction of oil consumed that could not have been supplied from domestic sources and is thus the most appropriate measure. With this issue of the Monthly Energy Review, the Energy Information Administration (EIA) introduces a revised table that expresses depend- ence on imports in terms of both measures. How dependent is the United States on foreign oil? How dependent are we on oil from the Persian Gulf or other sensitive areas? Do we import more than we produce domes-

Performer Energy & Environmental Research Center, Grand Forks, ND 58202-9018 Background The Bakken Formation is rapidly emerging as an important source of oil in the Williston Basin. The formation typically consists of three members, with the upper and lower members being shales and the middle member being dolomitic siltstone and sandstone. Total organic carbon (TOC) within the shales may be as high as 40%, with estimates of total hydrocarbon generation across the entire Bakken Formation ranging from 200 to 400 billion barrels. While the formation is productive in numerous reservoirs throughout Montana and North Dakota, with the Elm Coulee Field in Montana and the Parshall area in North Dakota being the most prolific examples of Bakken success, many Bakken wells have yielded disappointing results. While variable productivity within a play is nothing unusual to the petroleum industry, the Bakken play is noteworthy because of the wide variety of approaches and technologies that have been applied with apparently inconsistent and all too often underachieving results. This project will implement a robust, systematic, scientific, and engineering research effort to overcome these challenges and unlock the vast resource potential of the Bakken Formation in the Williston Basin.

Oil shale retort apparatus  

DOE Patents (OSTI)

A retorting apparatus including a vertical kiln and a plurality of tubes for delivering rock to the top of the kiln and removal of processed rock from the bottom of the kiln so that the rock descends through the kiln as a moving bed. Distributors are provided for delivering gas to the kiln to effect heating of the rock and to disturb the rock particles during their descent. The distributors are constructed and disposed to deliver gas uniformly to the kiln and to withstand and overcome adverse conditions resulting from heat and from the descending rock. The rock delivery tubes are geometrically sized, spaced and positioned so as to deliver the shale uniformly into the kiln and form symmetrically disposed generally vertical paths, or "rock chimneys", through the descending shale which offer least resistance to upward flow of gas. When retorting oil shale, a delineated collection chamber near the top of the kiln collects gas and entrained oil mist rising through the kiln.

Oil Prices and Inflation  

E-Print Network (OSTI)

As oil prices have climbed over the last several years, the memory of the 1970s and early 1980s has not been far from the minds of the public or of monetary policymakers. In those earlier episodes, rising oil prices were accompanied by doubledigit overall inflation in the U.S. and in several other developed economies. Indeed, central bankers say they are determined not to let this experience recur, emphasizing that they intend to maintain their credibility with the public in securing low inflation and achieving stable and well-anchored inflation expectations. In pursuing these goals, a key measure policymakers often focus on is core inflation; this may seem surprising, since core inflation excludes energy prices, among other things.

American oil producers are expected to pump a daily average of 6.4 million barrels of crude oil this year, according to the U.S. Energy Information Administrator's new monthly energy forecast. The annual increase in oil output tops the previous record set in 1951 and marks the largest yearly production increase ever. Most of the increase in crude oil production is driven by drilling activity in shale formations located in Texas, North Dakota and Montana. U.S. crude oil production next year is expected to top 7 million barrels per day for the first time

Production of Shale Oil  

E-Print Network (OSTI)

Intensive pre-project feasibility and engineering studies begun in 1979 have produced an outline plan for development of a major project for production of shale oil from private lands in the Piceance Basin in western Colorado. This outline plan provides a blueprint for the development of a 28,000 acre holding on Clear Creek in Garfield County, Colorado on property acquired by Standard Oil of California in the late 1940's and early 1950's. The paper describes these planning activities and the principal features of a proposed $5 billion project to develop facilities for production of 100,000 barrels per day of synthetic crude from oil shale. Subjects included are resource evaluation, environmental baseline studies, plans for acquisition of permits, plans for development of required retorting and mining technology and a preliminary description of the commercial project which will ultimately emerge from these activities. General financial impact of the project and the case for additional tax incentives to encourage it will be described.

"Future of oil supplies"  

E-Print Network (OSTI)

Oil is so important that publishing reserve (even production) data has become a political act. Most of the dispute between the so-called pessimists (mainly retired geologists) and the optimists (mainly economists) is due to their using different sources of information and different definitions. The pessimists use technical (confidential) data, whereas the optimists use the political (published) data. OPEC quotas are based on the reserves, explaining why its members raised their reserves from 1986 to 1990, adding about 300 Gb of oil reserves when only about 10 Gb was actually discovered during this period. There is consensus on neither the reserve numbers, nor the definition of terms, such as oil, gas, conventional, unconventional, reserves. The latter term may variously refer to current proven values or backdated mean values. The US practice is completely different from that in the rest of the world, being conservative to satisfy bankers and the stockmarket. By contrast, the FSU practice was over-optimistic being based on the maximum theoretical recovery, free of technological or economic constraints. All published data have to be re-worked to be able to compare like with like. Unfortunately confidentiality and politics make it difficult to obtain valid data.

Major Oil Plays in Utah and Vicinity  

Science Conference Proceedings (OSTI)

Utah oil fields have produced over 1.2 billion barrels (191 million m{sup 3}). However, the 13.7 million barrels (2.2 million m{sup 3}) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. The Utah Geological Survey believes this trend can be reversed by providing play portfolios for the major oil-producing provinces (Paradox Basin, Uinta Basin, and thrust belt) in Utah and adjacent areas in Colorado and Wyoming. Oil plays are geographic areas with petroleum potential caused by favorable combinations of source rock, migration paths, reservoir rock characteristics, and other factors. The play portfolios will include: descriptions and maps of the major oil plays by reservoir; production and reservoir data; case-study field evaluations; locations of major oil pipelines; identification and discussion of land-use constraints; descriptions of reservoir outcrop analogs; and summaries of the state-of-the-art drilling, completion, and secondary/tertiary techniques for each play. This report covers research activities for the sixth quarter of the project (October 1 through December 31, 2003). This work included describing outcrop analogs for the Jurassic Twin Creek Limestone and Mississippian Leadville Limestone, major oil producers in the thrust belt and Paradox Basin, respectively, and analyzing best practices used in the southern Green River Formation play of the Uinta Basin. Production-scale outcrop analogs provide an excellent view of reservoir petrophysics, facies characteristics, and boundaries contributing to the overall heterogeneity of reservoir rocks. They can be used as a ''template'' for evaluation of data from conventional core, geophysical and petrophysical logs, and seismic surveys. In the Utah/Wyoming thrust belt province, the Jurassic Twin Creek Limestone produces from subsidiary closures along major ramp anticlines where the low-porosity limestone beds are extensively fractured and sealed by overlying argillaceous and non-fractured units. The best outcrop analogs for Twin Creek reservoirs are found at Devils Slide and near the town of Peoa, Utah, where fractures in dense, homogeneous non-porous limestone beds are in contact with the basal siltstone units (containing sealed fractures) of the overlying units. The shallow marine, Mississippian Leadville Limestone is a major oil and gas reservoir in the Paradox Basin of Utah and Colorado. Hydrocarbons are produced from basement-involved, northwest-trending structural traps with closure on both anticlines and faults. Excellent outcrops of Leadville-equivalent rocks are found along the south flank of the Uinta Mountains, Utah. For example, like the Leadville, the Mississippian Madison Limestone contains zones of solution breccia, fractures, and facies variations. When combined with subsurface geological and production data, these outcrop analogs can improve (1) development drilling and production strategies such as horizontal drilling, (2) reservoir-simulation models, (3) reserve calculations, and (4) design and implementation of secondary/tertiary oil recovery programs and other best practices used in the oil fields of Utah and vicinity. In the southern Green River Formation play of the Uinta Basin, optimal drilling, development, and production practices consist of: (1) owning drilling rigs and frac holding tanks; (2) perforating sandstone beds with more than 8 percent neutron porosity and stimulate with separate fracture treatments; (3) placing completed wells on primary production using artificial lift; (4) converting wells relatively soon to secondary waterflooding maintaining reservoir pressure above the bubble point to maximize oil recovery; (5) developing waterflood units using an alternating injector--producer pattern on 40-acre (16-ha) spacing; and (6) recompleting producing wells by perforating all beds that are productive in the waterflood unit. As part of technology transfer activities during this quarter, an abstract describing outcrop reservoir analogs was accepted by the American Assoc

Fast Pyrolysis Oil Stabilization: An Integrated Catalytic and Membrane Approach for Improved Bio-oils  

Science Conference Proceedings (OSTI)

This University of Massachusetts, Amherst project, "Fast Pyrolysis Oil Stabilization: An Integrated Catalytic and Membrane Approach for Improved Bio-oils" started on 1st February 2009 and finished on August 31st 2011. The project consisted following tasks: Task 1.0: Char Removal by Membrane Separation Technology The presence of char particles in the bio-oil causes problems in storage and end-use. Currently there is no well-established technology to remove char particles less than 10 micron in size. This study focused on the application of a liquid-phase microfiltration process to remove char particles from bio-oil down to slightly sub-micron levels. Tubular ceramic membranes of nominal pore sizes 0.5 and 0.8 ���µm were employed to carry out the microfiltration, which was conducted in the cross-flow mode at temperatures ranging from 38 to 45 C and at three different trans-membrane pressures varying from 1 to 3 bars. The results demonstrated the removal of the major quantity of char particles with a significant reduction in overall ash content of the bio-oil. The results clearly showed that the cake formation mechanism of fouling is predominant in this process. Task 2.0 Acid Removal by Membrane Separation Technology The feasibility of removing small organic acids from the aqueous fraction of fast pyrolysis bio-oils using nanofiltration (NF) and reverse osmosis (RO) membranes was studied. Experiments were carried out with a single solute solutions of acetic acid and glucose, binary solute solutions containing both acetic acid and glucose, and a model aqueous fraction of bio-oil (AFBO). Retention factors above 90% for glucose and below 0% for acetic acid were observed at feed pressures near 40 bar for single and binary solutions, so that their separation in the model AFBO was expected to be feasible. However, all of the membranes were irreversibly damaged when experiments were conducted with the model AFBO due to the presence of guaiacol in the feed solution. Experiments with model AFBO excluding guaiacol were also conducted. NF membranes showed retention factors of glucose greater than 80% and of acetic acid less than 15% when operated at transmembrane pressures near 60 bar. Task 3.0 Acid Removal by Catalytic Processing It was found that the TAN reduction in bio-oil was very difficult using low temperature hydrogenation in flow and batch reactors. Acetic acid is very resilient to hydrogenation and we could only achieve about 16% conversion for acetic acid. Although it was observed that acetic acid was not responsible for instability of aqueous fraction of bio-oil during ageing studies (described in task 5). The bimetallic catalyst PtRe/ceria-zirconia was found to be best catalyst because its ability to convert the acid functionality with low conversion to gas phase carbon. Hydrogenation of the whole bio-oil was carried out at 125���°C, 1450 psi over Ru/C catalyst in a flow reactor. Again, negligible acetic acid conversion was obtained in low temperature hydrogenation. Hydrogenation experiments with whole bio-oil were difficult to perform because of difficulty to pumping the high viscosity oil and reactor clogging. Task 4.0 Acid Removal using Ion Exchange Resins DOWEX M43 resin was used to carry out the neutralization of bio-oil using a packed bed column. The pH of the bio-oil increased from 2.43 to 3.7. The GC analysis of the samples showed that acetic acid was removed from the bio-oil during the neutralization and recovered in the methanol washing. But it was concluded that process would not be economical at large scale as it is extremely difficult to regenerate the resin once the bio-oil is passed over it. Task 5.0 Characterization of Upgraded Bio-oils We investigated the viscosity, microstructure, and chemical composition of bio-oils prepared by a fast pyrolysis approach, upon aging these fuels at 90���ºC for periods of several days.

Fast Pyrolysis Oil Stabilization: An Integrated Catalytic and Membrane Approach for Improved Bio-oils  

SciTech Connect

This University of Massachusetts, Amherst project, "Fast Pyrolysis Oil Stabilization: An Integrated Catalytic and Membrane Approach for Improved Bio-oils" started on 1st February 2009 and finished on August 31st 2011. The project consisted following tasks: Task 1.0: Char Removal by Membrane Separation Technology The presence of char particles in the bio-oil causes problems in storage and end-use. Currently there is no well-established technology to remove char particles less than 10 micron in size. This study focused on the application of a liquid-phase microfiltration process to remove char particles from bio-oil down to slightly sub-micron levels. Tubular ceramic membranes of nominal pore sizes 0.5 and 0.8 ���µm were employed to carry out the microfiltration, which was conducted in the cross-flow mode at temperatures ranging from 38 to 45 C and at three different trans-membrane pressures varying from 1 to 3 bars. The results demonstrated the removal of the major quantity of char particles with a significant reduction in overall ash content of the bio-oil. The results clearly showed that the cake formation mechanism of fouling is predominant in this process. Task 2.0 Acid Removal by Membrane Separation Technology The feasibility of removing small organic acids from the aqueous fraction of fast pyrolysis bio-oils using nanofiltration (NF) and reverse osmosis (RO) membranes was studied. Experiments were carried out with a single solute solutions of acetic acid and glucose, binary solute solutions containing both acetic acid and glucose, and a model aqueous fraction of bio-oil (AFBO). Retention factors above 90% for glucose and below 0% for acetic acid were observed at feed pressures near 40 bar for single and binary solutions, so that their separation in the model AFBO was expected to be feasible. However, all of the membranes were irreversibly damaged when experiments were conducted with the model AFBO due to the presence of guaiacol in the feed solution. Experiments with model AFBO excluding guaiacol were also conducted. NF membranes showed retention factors of glucose greater than 80% and of acetic acid less than 15% when operated at transmembrane pressures near 60 bar. Task 3.0 Acid Removal by Catalytic Processing It was found that the TAN reduction in bio-oil was very difficult using low temperature hydrogenation in flow and batch reactors. Acetic acid is very resilient to hydrogenation and we could only achieve about 16% conversion for acetic acid. Although it was observed that acetic acid was not responsible for instability of aqueous fraction of bio-oil during ageing studies (described in task 5). The bimetallic catalyst PtRe/ceria-zirconia was found to be best catalyst because its ability to convert the acid functionality with low conversion to gas phase carbon. Hydrogenation of the whole bio-oil was carried out at 125���°C, 1450 psi over Ru/C catalyst in a flow reactor. Again, negligible acetic acid conversion was obtained in low temperature hydrogenation. Hydrogenation experiments with whole bio-oil were difficult to perform because of difficulty to pumping the high viscosity oil and reactor clogging. Task 4.0 Acid Removal using Ion Exchange Resins DOWEX M43 resin was used to carry out the neutralization of bio-oil using a packed bed column. The pH of the bio-oil increased from 2.43 to 3.7. The GC analysis of the samples showed that acetic acid was removed from the bio-oil during the neutralization and recovered in the methanol washing. But it was concluded that process would not be economical at large scale as it is extremely difficult to regenerate the resin once the bio-oil is passed over it. Task 5.0 Characterization of Upgraded Bio-oils We investigated the viscosity, microstructure, and chemical composition of bio-oils prepared by a fast pyrolysis approach, upon aging these fuels at 90���ºC for periods of several days. Our results suggest that the viscosity increase is not correlated with the acids or char present in the bio-oils. The

Impact of 1980 scheduled capacity additions on electric-utility oil consumption  

SciTech Connect

The electric-utility sector currently consumes approximately 8% of the total oil used in the Nation. This oil represented about 15% of total fuel consumed by electric utilities in 1979. Two important factors that affect the level of utility oil consumption in 1980 are the substantial increase in coal-fired generating capacity and the uncertainty surrounding nuclear-plant licensing. With particular emphasis on these considerations, this report analyzes the potential for changes in electric-utility oil consumption in 1980 relative to the 1979 level. Plant conversions, oil to coal, for example, that may occur in 1980 are not considered in this analysis. Only the potential reduction in oil consumption resulting from new generating-capacity additions is analyzed. Changes in electric-utility oil consumption depend on, among other factors, regional-electricity-demand growth and generating-plant mix. Five cases are presented using various electricity-demand-growth rate assumptions, fuel-displacement strategies, and nuclear-plant-licensing assumptions. In general, it is likely that there will be a reduction in electric-utility oil consumption in 1980. Using the two reference cases of the report, this reduction is projected to amount to a 2 to 5% decrease from the 1979 oil-consumption level; 7% reduction is the largest reduction projected.

Evaluation of Reservoir Wettability and its Effect on Oil Recovery.  

SciTech Connect

We report on the first year of the project, `Evaluation of Reservoir Wettability and its Effect on Oil Recovery.` The objectives of this five-year project are (1) to achieve improved understanding of the surface and interfacial properties of crude oils and their interactions with mineral surfaces, (2) to apply the results of surface studies to improve predictions of oil production from laboratory measurements, and (3) to use the results of this research to recommend ways to improve oil recovery by waterflooding. During the first year of this project we have focused on understanding the interactions between crude oils and mineral surfaces that establish wetting in porous media. As background, mixed-wetting and our current understanding of the influence of stable and unstable brine films are reviewed. The components that are likely to adsorb and alter wetting are divided into two groups: those containing polar heteroatoms, especially organic acids and bases; and the asphaltenes, large molecules that aggregate in solution and precipitate upon addition of n-pentane and similar agents. Finally, the test procedures used to assess the extent of wetting alteration-tests of adhesion and adsorption on smooth surfaces and spontaneous imbibition into porous media are introduced. In Part 1, we report on studies aimed at characterizing both the acid/base and asphaltene components. Standard acid and base number procedures were modified and 22 crude oil samples were tested. Our approach to characterizing the asphaltenes is to focus on their solvent environment. We quantify solvent properties by refractive index measurements and report the onset of asphaltene precipitation at ambient conditions for nine oil samples. Four distinct categories of interaction mechanisms have been identified that can be demonstrated to occur when crude oils contact solid surfaces: polar interactions can occur on dry surfaces, surface precipitation is important if the oil is a poor solvent for its asphaltenes, and acid/base and ion-binding interactions occur in the presence of water. Specific instances when each of these mechanisms is dominant can be identified using crude oils of different acid number, base number, and solvent quality. Part 2 of this project is devoted to improved assessment of wetting. We report on a baseline study of crude oil interactions with mica surfaces that shows wettability alteration characteristics that are comparable to those reported previously for glass surfaces. Mica has advantages over amorphous glass that make it a better choice as a standard surface for wettability testing, especially for tests at high temperatures.

The Outlook for U.S. Oil Dependence  

Science Conference Proceedings (OSTI)

Market share OPEC lost in defending higher prices from 1979-1985 is being steadily regained and is projected to exceed 50% by 2000. World oil markets are likely to be as vulnerable to monopoly influence as they were 20 years ago, as OPEC regains lost market share. The US economy appears to be as exposed as it was in the early 1970s to losses from monopoly oil pricing. A simulated 2-year supply reduction in 2005-6 boosts OPEC revenues by roughly half a trillion dollars and costs the US economy an approximately equal amount. The Strategic Petroleum Reserve appears to be of little benefit against such a determined, multi-year supply curtailment either in reducing OPEC revenues or protecting the US economy. Increasing the price elasticity of oil demand and supply in the US and the rest of the world, however, would be an effective strategy.

Pipeline issues shape southern FSU oil, gas development  

SciTech Connect

To future production from southern republics of the former Soviet Union (FSU), construction and revitalization of pipelines are as important as the supply of capital. Export capacity will limit production and slow development activity in the region until new pipelines are in place. Plenty of pipeline proposals have come forward. The problem is politics, which for every proposal so far complicates routing or financing or both. Russia has made clear its intention to use pipeline route decisions to retain influence in the region. As a source of external pressure, it is not alone. Iran and Turkey also have made strong bids for the southern FSU`s oil and gas transport business. Diplomacy thus will say as much as commerce does about how transportation issues are settled and how quickly the southern republics move toward their potentials to produce oil and gas. The paper discusses possible routes and the problems with them, the most likely proposal, and future oil flows.

Impacts of the Weatherization Assistance Program in fuel-oil heated houses  

Science Conference Proceedings (OSTI)

The U.S. DOE Weatherization Assistance Program (WAP) Division requested Oak Ridge National Laboratory to help design and conduct an up-to-date assessment of the Program. The evaluation includes five separate studies; the fuel oil study is the subject of this paper. The primary goal of the fuel-oil study was to provide a region-wide estimate of the space-heating fuel oil saved by the Program in the Northeast during the 1991 and 1992 program years. Other goals include assessing the cost effectiveness of the Program within the fuel-oil submarket, and identifying factors which caused fuel-oil savings to vary. This paper reports only the highlights from the fuel-oil study`s final report.

Deposit information in gasoline engines: Part I. Base oil effects in sequence VE deposits  

SciTech Connect

Base oil effects on sludge and deposit formation in the ASTM Sequence VE were studied with blends made using the same American Petroleum Institute (API) SG performance package and the same viscosity improver. One percent of the dispersant was removed from the formulation to accentuate base oil effects. Nine tests on six different 100N base oils were run. Sequence VE test lubricant drain analyses show differences in insolubles, viscosity, and particle size with base stock variations. The most significant base oil factors which can be used to predict Sequence VE sludge ratings are the base oil saturate content, polar content, and volatility. While all oils studied passed the Sequence VE API SG engine varnish and piston varnish requirements, higher levels of poly-nuclear aromatics (PNA`s) are shown to increase the severity of these ratings.

Consumer Winter Heating Oil Costs  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: Using the Northeast as a regional focus for heating oil, the typical oil-heated household consumes about 680 gallons of oil during the winter, assuming that weather is "normal." The previous three winters were warmer than average and generated below normal consumption rates. Last winter, consumers saw large increases over the very low heating oil prices seen during the winter of 1998-1999 but, outside of the cold period in late January/early February they saw relatively low consumption rates due to generally warm weather. Even without particularly sharp cold weather events this winter, we think consumers are likely to see higher average heating oil prices than were seen last winter. If weather is normal, our projections imply New England heating oil

Retail Diesel Fuel Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

Along with heating oil prices, the distillate supply squeeze has Along with heating oil prices, the distillate supply squeeze has severely impacted diesel fuel prices, especially in the Northeast. Diesel fuel is bascially the same product as home heating oil. The primary difference is that diesel has a lower sulfur content. When heating oil is in short supply, low sulfur diesel fuel can be diverted to heating oil supply. Thus, diesel fuel prices rise with heating heating oil prices. Retail diesel fuel prices nationally, along with those of most other petroleum prices, increased steadily through most of 1999. But prices in the Northeast jumped dramatically in the third week of January. Diesel fuel prices in New England rose nearly 68 cents per gallon, or 47 percent, between January 17 and February 7.

Horizontal oil well applications and oil recovery assessment. Technical progress report, April--June 1994  

SciTech Connect

Thousands of horizontal wells are being drilled each year in the U.S.A. and around the world. Horizontal wells have increased oil and gas production rates 3 to 8 times those of vertical wells in many areas and have converted non-economic oil reserves to economic reserves. However, the use of horizontal technology in various formation types and applications has not always yielded anticipated success. The primary objective of this project is to examine factors affecting technical and economic success of horizontal well applications. The project`s goals will be accomplished through six tasks designed to evaluate the technical and economic success of horizontal drilling, highlight current limitations, and outline technical needs to overcome these limitations. Data describing operators` experiences throughout the domestic oil and gas industry will be gathered and organized. Canadian horizontal technology will also be documented with an emphasis on lessons the US industry can learn from Canada`s experience. MEI databases containing detailed horizontal case histories will also be used. All these data will be categorized and analyzed to assess the status of horizontal well technology and estimate the impact of horizontal wells on present and future domestic oil recovery and reserves.

Aggregation and transport kinetics of crude oil and sediment in estuarine waters  

E-Print Network (OSTI)

Modeling the transport and fate of spilled crude oil is important for estimating short and long-term toxicity effects in coastal ecosystems. This research project investigates the partitioning of hydrocarbons from a surface crude oil slick, the resurfacing of chemically dispersed crude oil droplets, the suitability of in-situ field instruments for oil and sediment characterization, and the aggregation and settling of dispersed oil and suspended sediments. An initial laboratory study was conducted to investigate apparent hydrocarbon solubility in petroleum/water systems. Mixing shear and initial crude oil layer thickness were related empirically to oil entrainment rate. A model describing hydrocarbons partitioned in colloidal and soluble phases was consistent with experimental data. A second laboratory study was conducted to investigate the influence of coalescence kinetics on mean droplet size and resurfacing rate of chemically dispersed crude oil droplets. Increased mean shear rates resulted in mean droplet diameters and oil resurfacing rates. A third laboratory study was conducted to compare particle size and fractal dimension measurements obtained using a submersible flow cytometer, an electrozone particle counter, and a light scattering particle sizer. Measured particles included latex beads, crude oil, clay, crude oil-clay aggregates, and crude oil-silica aggregates. Tested instruments gave consistent size measurements for all particle systems, suggesting their suitability for sizing marine particles. To describe the aggregation kinetics of oil-sediment systems, a modified Smoluchowski model based on coalesced sphere (CS) assumptions was developed. Observed collision efficiency values (?OBS) were related to collision efficiency values for single particle type systems (?HOMO) and those for two particle type systems (?HET) using a probabilistic approach. For clay and crude oil, ?HOMO values were higher than the ?HOMO value for silica. Clay-oil and silica-oil have similar ?HET values. Thus, crude oil can significantly increase the aggregation rates of noncohesive sediments such as silica. The CS model above was modified to incorporate sediment fractal geometry. The ability of this modified coalesced fractal sphere (mCFS) model to fit experimental data sets was better than that of a coalesced sphere (CS) model. Because of their reduced settling rates, sediments with lower fractal dimension form more aggregate with dispersed oil.

Enhanced Oil Recovery of Viscous Oil by Injection of Water-in-Oil Emulsion Made with Used Engine Oil  

E-Print Network (OSTI)

Solids-stabilized water-in-oil emulsions have been suggested as a drive fluid to recover viscous oil through a piston-like displacement pattern. While crude heavy oil was initially suggested as the base oil, an alternative oil ? used engine oil was proposed for emulsion generation because of several key advantages: more favorable viscosity that results in better emulsion injectivity, soot particles within the oil that readily promote stable emulsions, almost no cost of the oil itself and relatively large supply, and potential solution of used engine oil disposal. In this research, different types of used engine oil (mineral based, synthetic) were tested to make W/O emulsions simply by blending in brine. A series of stable emulsions was prepared with varied water contents from 40~70%. Viscosities of these emulsions were measured, ranging from 102~104 cp at low shear rates and ambient temperature. Then an emulsion made of 40% used engine oil and 60% brine was chosen for a series of coreflood experiments, to test the stability of this emulsion while flowing through porous media. Limited breakdown of the effluent was observed at ambient injection rates, indicating a stability of the emulsion in porous media. Pressure drops leveled off and remained constant at constant rate of injection, indicating steady-state flows under the experimental conditions. No plug off effect was observed after a large volume of emulsion passed through the cores. Reservoir scale simulations were conducted for the emulsion flooding process based on the emulsion properties tested from the experiments. Results showed significant improvement in both displacement pattern and oil recovery especially compared to water flooding. Economics calculations of emulsion flooding were also performed, suggesting this process to be highly profitable.

Future world oil prices: modeling methodologies and summary of recent forecasts  

SciTech Connect

This paper has three main objectives. First, the various methodologies that have been developed to explain historical oil price changes and forecast future price trends are reviewed and summarized. Second, the paper summarizes recent world oil price forecasts, and, then possible, discusses the methodologies used in formulating those forecasts. Third, utilizing conclusions from the reviews of the modeling methodologies and the recent price forecasts, in combination with an assessment of recent and projected oil market trends, oil price projections are given for the time period 1987 to 2022. The paper argues that modeling methodologies have undergone significant evolution during the past decade as modelers increasingly recognize the complex and constantly changing structure of the world oil market. Unfortunately, at this point in time a consensus about the appropriate methodology to use in formulating oil price forecasts is yet to be reached. There is, however, a general movement toward the opinion that both economic and political factors should be considered when making price projections. Likewise, there is no consensus about future oil price trends. Forecasts differ widely. However, in general, forecasts have been adjusted downwardly in recent years. Further, an overall assessment of the forecasts and recent oil market trends suggests that oil prices will remain constant in real terms for the remainder of the 1980s. Real oil prices are expected to increase by between 2 and 3% during the 1990s and beyond. Forecasters are quick to point out, however, that all forecasts are subject to significant uncertainty. 69 references, 3 figures, 10 tables.

Process for heating coal-oil slurries  

DOE Patents (OSTI)

Controlling gas to slurry volume ratio to achieve a gas holdup of about 0.4 when heating a flowing coal-oil slurry and a hydrogen containing gas stream allows operation with virtually any coal to solvent ratio and permits operation with efficient heat transfer and satisfactory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry will depend on numerous factors such as coal concentration, coal particle size distribution, composition of the solvent (including recycle slurries), and type of coal. Further system efficiency can be achieved by operating with multiple heating zones to provide a high heat flux when the apparent viscosity of the gas saturated slurry is highest. Operation with gas flow rates below the critical minimum results in system instability indicated by temperature excursions in the fluid and at the tube wall, by a rapid increase and then decrease in overall pressure drop with decreasing gas flow rate, and by increased temperature differences between the temperature of the bulk fluid and the tube wall. At the temperatures and pressures used in coal liquefaction preheaters the coal-oil slurry and hydrogen containing gas stream behaves essentially as a Newtonian fluid at shear rates in excess of 150 sec[sup [minus]1]. The gas to slurry volume ratio should also be controlled to assure that the flow regime does not shift from homogeneous flow to non-homogeneous flow. Stable operations have been observed with a maximum gas holdup as high as 0.72. 29 figs.

DOE Patents (OSTI)

Controlling gas to slurry volume ratio to achieve a gas holdup of about 0.4 when heating a flowing coal-oil slurry and a hydrogen containing gas stream allows operation with virtually any coal to solvent ratio and permits operation with efficient heat transfer and satisfactory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry will depend on numerous factors such as coal concentration, coal particle size distribution, composition of the solvent (including recycle slurries), and type of coal. Further system efficiency can be achieved by operating with multiple heating zones to provide a high heat flux when the apparent viscosity of the gas saturated slurry is highest. Operation with gas flow rates below the critical minimum results in system instability indicated by temperature excursions in the fluid and at the tube wall, by a rapid increase and then decrease in overall pressure drop with decreasing gas flow rate, and by increased temperature differences between the temperature of the bulk fluid and the tube wall. At the temperatures and pressures used in coal liquefaction preheaters the coal-oil slurry and hydrogen containing gas stream behaves essentially as a Newtonian fluid at shear rates in excess of 150 sec.sup. -1. The gas to slurry volume ratio should also be controlled to assure that the flow regime does not shift from homogeneous flow to non-homogeneous flow. Stable operations have been observed with a maximum gas holdup as high as 0.72.

Oil cooled, hermetic refrigerant compressor  

DOE Patents (OSTI)

A hermetic refrigerant compressor having an electric motor and compressor assembly in a hermetic shell is cooled by oil which is first cooled in an external cooler and is then delivered through the shell to the top of the motor rotor where most of it is flung radially outwardly within the confined space provided by the cap which channels the flow of most of the oil around the top of the stator and then out to a multiplicity of holes to flow down to the sump and provide further cooling of the motor and compressor. Part of the oil descends internally of the motor to the annular chamber to provide oil cooling of the lower part of the motor, with this oil exiting through vent hole also to the sump. Suction gas with entrained oil and liquid refrigerant therein is delivered to an oil separator from which the suction gas passes by a confined path in pipe to the suction plenum and the separated oil drops from the separator to the sump. By providing the oil cooling of the parts, the suction gas is not used for cooling purposes and accordingly increase in superheat is substantially avoided in the passage of the suction gas through the shell to the suction plenum. 3 figs.

Solar retorting of oil shale  

DOE Patents (OSTI)

An apparatus and method for retorting oil shale using solar radiation. Oil shale is introduced into a first retorting chamber having a solar focus zone. There the oil shale is exposed to solar radiation and rapidly brought to a predetermined retorting temperature. Once the shale has reached this temperature, it is removed from the solar focus zone and transferred to a second retorting chamber where it is heated. In a second chamber, the oil shale is maintained at the retorting temperature, without direct exposure to solar radiation, until the retorting is complete.

Microbiology for enhanced oil recovery  

Science Conference Proceedings (OSTI)

The U. S. Department of Energy has sponsored several projects to investigate the feasibility of using microorganisms to enhance oil recovery. Microbes from the Wilmington oilfield, California, were found to be stimulated in growth by polyacrylamide mobility-control polymers and the microbes also can reduce the viscosity of the polyacrylamide solutions. Microbes have been discovered that produce surface active molecules, and several mixed cultures have been developed that make low viscosity, non-wetting, emulsions of heavy oils (/sup 0/API oil deposits, in China for enhanced recovery of light oils and successful field tests have been conducted in Romania and Arkansas.

EIA - International Energy Outlook 2008-Defining the Limits of Oil  

Gasoline and Diesel Fuel Update (EIA)

Defining the Limits of Oil Production Defining the Limits of Oil Production Preparing mid-term projections of oil production requires an assessment of the availability of resources to meet production requirements, particularly for the later years of the 2005-2030 projection period in IEO2008. The IEO2008 oil production projections were limited by three factors: the estimated quantity of petroleum in place before production begins (“petroleum-initially-in-place” or IIP), the percentage of IIP extracted over the life of a field (ultimate recovery factor), and the amount of oil that can be produced from a field in a single year as a function of its remaining reserves. Total IIP resources are the quantities of petroleum—both conventional and unconventional—estimated to exist originally in naturally occurring accumulations.a IIP resources are those quantities of petroleum which are estimated, on a given date, to be contained in known accumulations, plus those quantities already produced, as well as those estimated quantities in accumulations yet to be discovered. The estimate of IIP resources includes both recoverable and unrecoverable resources.

Crude oil steam distillation in steam flooding. Final report  

SciTech Connect

Steam distillation yields of sixteen crude oils from various parts of the United States have been determined at a saturated steam pressure of 200 psig. Study made to investigate the effect of steam pressure (200 to 500 psig) on steam distillation yields indicates that the maximum yields of a crude oil may be obtained at 200 psig. At a steam distillation correlation factor (V/sub w//V/sub oi/) of 15, the determined steam distillation yields range from 12 to 56% of initial oil volume for the sixteen crude oils with gravity ranging from 12 to 40/sup 0/API. Regression analysis of experimental steam distillation yields shows that the boiling temperature (simulated distillation temperature) at 20% simulated distillation yield can predict the steam distillation yields reasonably well: the standard error ranges from 2.8 to 3.5% (in yield) for V/sub w//V/sub oi/ < 5 and from 3.5 to 4.5% for V/sub w//V/sub oi/ > 5. The oil viscosity (cs) at 100/sup 0/F can predict the steam distillation yields with standard error from 3.1 to 4.3%. The API gravity can predict the steam distillation yields with standard error from 4.4 to 5.7%. Characterization factor is an unsatisfactory correlation independent variable for correlation purpose.

Empirical characterization of oil shale fragmentation experiments  

SciTech Connect

Shale oil recovery rates that can be achieved in underground in situ retorts can be strongly influenced by the shale breakage and fragment-size distribution achieved during rubblization. Since the fragmentation pattern in the retort is a direct result of the blast design used for rubblization, the characterizing blast parameters should be carefully selected. Explosives should be matched to the host material and blast geometries properly chosen so that the required fragmentation results are achieved at optimum costs. Special attention must be directed to selecting blast parameters that produce uniform bed permeability, suppression of fines, proper fragment size distribution, and minimal damage to the retort walls and ceiling. The influence of joints and natural fractures should also be known. In instances where the requisite blasting parameters are unknown, they should be determined from test blasts. Small and intermediate size cratering and bench blast experiments are being made to determine critical depths, volume crater constants, and fragment-size distribution scaling constants for Piceance Creek Basin oil shale. The small tests are made using PETN explosive in meter-sized blocks. The intermediate-sized tests are on the ten-to-twenty foot scale using an ANFO explosive. The experiments are designed to investigate the adequacy of using empirical scaling laws to describe the influence of bedding plane orientation, burden distance, explosive energy release, and borehole diameter on blast results. Crater volumes, sieved fragment-size distributions, free surface velocities, and explosive detonation velocities are measured. Data are treated using a Livingston type performance evaluation based on explosive volume to determine critical and optimum depths. Measured fragment-size distributions are interpreted using empirical scaling techniques.

The role of recycle oil in direct coal liquefaction process development  

Science Conference Proceedings (OSTI)

It has long been recognized that use of a recycle oil is a convenient and perhaps necessary feature of a practical direct coal liquefaction process. The recycle oil performs a number of important functions. It serves as a vehicle to convey coal into the liquefaction reactor and products from the reactor. It is a medium for mass and heat transfer among the solid, liquid, and gaseous components of the reactor inventory. It can act as a reactant or intermediate in the liquefaction process. Therefore, the nature of the recycle oil can have a determining effect on process configuration and performance, and the characterization of recycle oil composition and chemistry has been the subject of considerable interest. This paper discusses recycle oil characterization and its influence on the industrial development of coal liquefaction technology,

Upgrading and enhanced recovery of Jobo heavy oil using hydrogen donor under in-situ combustion  

E-Print Network (OSTI)

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