    The ferrite process is an established technique for removing heavy metals from waste water. Because the process water resulting from oil shale beneficiation falls into the category of industrial waste water, it is anticipated that this process may turn out to be a potential viable treatment for oil shale beneficiation process water containing many heave metal ions. The process is chemoremedial because not only effluent water comply with quality standards, but harmful heavy metals are converted into a valuable, chemically stable by-product known as ferrite. These spinel ferrites have magnetic properties, and therefore can be use in applications such as magnetic marker, ferrofluid, microwave absorbing and scavenging material. Experimental results from this process are presented along with results of treatment technique such as sulfide precipitation.

    Oxidized oil shale from the combustor in the LLNL Hot-Recycled-Solids (HRS) oil shale retorting process has been found to be a catalyst for removing nitrogen oxides from laboratory gas streams using NH{sub 3} as a reductant. Oxidized Green River oil shale heated at 10{degree}C/min in an Ar/O{sub 2}/NO/NH{sub 3} mixture ({approximately}93%/6%/2000 ppM/4000 ppM) with a gas residence time of {approximately}0.6 sec removed NO between 250 and 500{degree}C, with maximum removal of 70% at {approximately}400{degree}C. Under isothermal conditions with the same gas mixture, the maximum NO removal was {approximately}64%. When CO{sub 2} was added to the gas mixture at {approximately}8%, the NO removal dropped to {approximately}50%. However, increasing the gas residence time to {approximately}1.2 sec, increased NO removal to 63%. Nitrogen balances of these experiments suggest selective catalytic reduction of NO is occurring using NH{sub 3} as the reductant. These results are not based on completely optimized process conditions, but indicate oxidized oil shale is an effective catalyst for NO removal from combustion gas streams using NH{sub 3} as the reductant. Parameters calculated for implementing oxidized oil shale for NO{sub x} remediation on the current HRS retort indicate an abatement device is practical to construct.

    Waste oils offer a tremendous recycling potential. An important, dwindling natural resource of great economic and industrial value, oil products are a cornerstone of our modern industrial society. Petroleum is processed into a wide variety of products: gasoline, fuel oil, diesel oil, synthetic rubber, solvents, pesticides, synthetic fibres, lubricating oil, drugs and many more ' (see Figure 1 1. The boilers of Amercian industries presently consume about 40 % of the used lubricating oils collected. In Ontario, the percentage varies from 20 to 30%. Road oiling is the other major use of collected waste oils. Five to seven million gallons (50-70 % of the waste oil col1ected)is spread on dusty Ontario roads each summer. The practice is both a wasteful use of a dwindling resource and an environmental hazard. The waste oil, with its load of heavy metals, particularly lead, additives including dangerous polynuclear aromatics and PCBs, is carried into the natural environment by runoff and dust to contaminate soils and water courses.2 The largest portion of used oils is never collected, but disappears into sewers, landfill sites and backyards. In Ontario alone, approximately 22 million gallons of potentially recyclable lube oil simply vanish each year. While oil recycling has ad-114 Oil

    Western Research Institute (WRI), in conjunction with the U.S. Department of Energy (DOE), conducted a study of using the layered double hydroxides (LDH) as filter material to remove microorganisms, large biological molecules, certain anions and toxic oxyanions from various waste streams, including wastewater from refineries. Results demonstrate that LDH has a high adsorbing capability to those compounds with negative surface charge. Constituents studied include model bacteria, viruses, arsenic, selenium, vanadium, diesel range hydrocarbons, methyl tert-butyl ether (MTBE), mixed petroleum constituents, humic materials and anions. This project also attempted to modify the physical structure of LDH for the application as a filtration material. Flow characterizations of the modified LDH materials were also investigated. Results to date indicate that LDH is a cost-effective new material to be used for wastewater treatment, especially for the treatment of anions and oxyanions.

  5. An Analysis of Surface and Subsurface Lineaments and Fractures for Oil and Gas Exploration in the Mid-Continent Region

    SciTech Connect (OSTI)

    An extensive literature search was conducted and geological and mathematical analyses were performed to investigate the significance of using surface lineaments and fractures for delineating oil and gas reservoirs in the Mid-Continent region. Tremendous amount of data were acquired including surface lineaments, surface major fracture zones, surface fracture traces, gravity and magnetic lineaments, and Precambrian basement fault systems. An orientation analysis of these surface and subsurface linear features was performed to detect the basic structural grains of the region. The correlation between surface linear features and subsurface oil and gas traps was assessed, and the implication of using surface lineament and fracture analysis for delineating hydrocarbon reservoirs in the Mid-Continent region discussed. It was observed that the surface linear features were extremely consistent in orientation with the gravity and magnetic lineaments and the basement faults in the Mid-Continent region. They all consist of two major sets bending northeast and northwest, representing, therefore, the basic structural grains of the region. This consistency in orientation between the surface and subsurface linear features suggests that the systematic fault systems at the basement in the Mid-Continent region have probably been reactivated many times and have propagated upward all the way to the surface. They may have acted as the loci for the development of other geological structures, including oil and gas traps. Also observed was a strong association both in orientation and position between the surface linear features and the subsurface reservoirs in various parts of the region. As a result, surface lineament and fracture analysis can be used for delineating additional oil and gas reserves in the Mid-Continent region. The results presented in this paper prove the validity and indicate the significance of using surface linear features for inferring subsurface oil and gas reservoirs in the Mid-Continent region. Any new potential oil and gas reservoirs in the Mid-Continent region, if they exist, will be likely associated with the northeast- and northwest-trending surface lineaments and fracture traces in the region.

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

    1993-08-01T23:59:59.000Z

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

    1980-06-01T23:59:59.000Z

    This manual presents a rationale for sampling designs, and results of geochemical baseline studies in the Colorado portion of the oil-shale region. The program consists of a systematic trace element study of soils, stream sediments, and plants carried out in a way to be conservative of human and financial resources and yield maximum information. Extension of this approach to other parameters, other locations, and to environmental baseline studies in general is a primary objective. A baseline for any geochemical parameter can be defined as the concentration of that parameter in a given medium such as soil, the range of its concentration, and the geographic scale of variability. In air quality studies, and to a lesser extent for plants, the temporal scale of variability must also be considered. In studies of soil, the temporal variablility does not become a factor until such time that a study is deemed necessary to evaluate whether or not there have been changes in baseline levels as a result of development. The manual is divided into five major parts. The first is a suggested sampling protocol which is presented in an outline form for guiding baseline studies in this area. The second section is background information on the physical features of the area of study, trace elements of significance occurring in oil shale, and the sample media used in these studies. The third section is concerned primarily with sampling design and its application to the geochemical studies of the oil shale region. The last sections, in the form of appendices, provide actual data and illustrate in a systematic manner, the calculations performed to obtain the various summary data. The last segment of the appendices is a more academic discussion of the geochemistry of trace elements and the parameters of importance influencing their behavior in natural systems.

    Possibilities in principle for satisfactory removal of the 180-azimuthal ambiguity in the transverse field of vector magnetograms and the extrapolation of magnetic fields independently of their position on the solar disk are shown. Revealed here is an exact correspondence between the estimated field and the nonpotential loop structure on the limb. The Metropolis's algorithm modified to work in spherical geometry is used to resolve the azimuthal ambiguity. Based on a version of the optimization method from Rudenko and Myshyakov (2009), we use corrected magnetograms as boundary conditions for magnetic field extrapolation in the nonlinear force-free approximation.

    The accumulation of oil requires a favorable source, a reservoir, good seal-rock quality, and suitably timed thermal history and structuring. The accumulated oil, especially its light fractions, may be subsequently removed by hydrologically controlled processes such as water washing, biodegradation, and tilting of the oil-water contact. These processes are dependent on the climate. In regions that have become increasingly cold or dry during late Cenozoic time, low rainfall, low ground-water flow rates, and low input of nutrients and microorganisms have protected the oil; in warm or temperate rainy climates, high flow rates and high input of nutrients and microorganisms have led to partial or total removal of oil. Thus, most of the rich (>500,000 barrels/day) oil provinces on land are in cold or dry regions, where water is recharged in highlands that receive little rain (<500 mm/yr), such as Texas, Oklahoma, Wyoming, Alaska's North Slope, California, Algeria, Libya, Egypt, the Middle East, the Volga-Ural basin, and western Siberia. Where upland recharge areas are warm or temperate and rainy, as in the eastern United States, western Europe, sub-Saharan Africa, Brazil, India, and most of China, rich oil provinces on land (outside young deltas) are rare, and biodegradation is widespread. 32 refs., 2 figs.

    The Petroleum Technology Transfer Council (PTTC) and cooperating Regional Lead Organizations (RLOs) in its South Midcontinent (Oklahoma Geological Survey, Norman, Oklahoma) and West Coast (University of Southern California, Los Angeles, California) regions conducted a ''Mentor-Based Effort to Advance Implementation of Preferred Management Practices (PMPs) For Oil Producers'' (DE-FC26-01BC15272) under an award in Phase I of Department of Energy's (DOE's) PUMP (Preferred Upstream Management Practices) program. The project's objective was to enable producers in California, Oklahoma and Arkansas to increase oil production, moderating or potentially reversing production declines and extending the life of marginal wells in the near term. PTTC identified the primary constraints inhibiting oil production through surveys and PUMPer direct contacts in both regions. The leading common constraint was excess produced water and associated factors. Approaches for addressing this common constraint were tailored for each region. For Oklahoma and Arkansas, the South Midcontinent Region developed a concise manual titled ''Produced Water And Associated Issues'' that led to multiple workshops across the region, plus workshops in several other regions. In California, the West Coast Region leveraged PUMP funding to receive an award from the California Energy Commission for $300,000 to systematically evaluate water control solutions for the California geological environment. Products include still-developing remedial action templates to help producers identify underlying causes of excess water production and screen appropriate solutions. Limited field demonstrations are being implemented to build producer confidence in water control technologies. Minor leverage was also gained by providing technology transfer support to a Global Energy Partners project that demonstrated affordable approaches for reducing power consumption. PTTC leveraged PUMP project results nationally through expanding workshops to other regions, providing coverage in its newsletter, through columns and case studies in trade journals, and through coordinating presentations at association and professional society meetings. Combined, there were more than 800 participants. Applying ''application percentages'' from PTTC's total technology transfer program, more than 250 participants are likely to be applying technologies (39% of industry participants). Polymer gel water-shutoff (WSO) treatments and wellbore management were a focus in the Midcontinent area. A major provider of polymer gel WSO treatments has experienced a significant increase in treatment activity in Oklahoma, some of which can be logically attributed to this project. A provider of polylined tubing, a product related to wellbore management, has noted a 280% increase in their independent customer base and opening of a new market due to their involvement in PUMP-spinoff technology transfer. Detailed case studies on polymer gel WSO treatments and wellbore management, along with more global analyses, demonstrate the economic value of these technologies to producers. Among the many information sources that producers consider when applying technology, PTTC knows it is an important source in these technology areas.

    DOE Data Explorer [Office of Scientific and Technical Information (OSTI)]

    Shay, Johanna Y.

    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.

    1993-07-01T23:59:59.000Z

    This report is one of a series of publications from a project considering the feasibility of increasing domestic heavy oil (10{degree} to 20{degree} API gravity inclusive) production being conducted for the US Department of Energy. The report includes projections of future heavy oil production at three production levels: 900,000; 500,000; and 300,000 BOPD above the current 1992 heavy oil production level of 750,000 BOPD. These free market scenario projections include time frames and locations. Production projections through a second scenario were developed to examine which heavy oil areas would be developed if significant changes in the US petroleum industry occurred. The production data helps to define the possible constraints (impact) of increased heavy oil production on the US refining industry (the subject of a future report). Constraints include a low oil price and low rate of return. Heavy oil has high production, transportation, and refining cost per barrel as compared to light oil. The resource is known, but the right mix of technology and investment is required to bring about significant expansion of heavy oil production in the US.

    Application of advanced high power laser technology into oil and gas well drilling has been attracting significant research interests recently among research institutes, petroleum industries, and universities. Potential laser or laser-aided oil and gas well drilling has many advantages over the conventional rotary drilling, such as high penetration rate, reduction or elimination of tripping, casing, and bit costs, and enhanced well control, perforating and side-tracking capabilities. The energy required to remove a unit volume of rock, namely the specific energy (SE), is a critical rock property data that can be used to determine both the technical and economic feasibility of laser oil and gas well drilling.

    Micronized coal is removed from coal-bearing steam by spraying stabilized petroleum oil into the steam and directing the resultant stream at a separation surface on which a coal-oil slurry is deposited and collected. Apparatus includes conduits which direct the resultant stream downward into a housing and normal to a surface on which the slurry is deposited by impact forces. In additional apparatus disclosed, the resultant stream is directed from a horizontal conduit circumferentially along the interior wall of a horizontally disposed cylindrical chamber at the top of the chamber and the coal-oil slurry deposited on the wall by centrifugal force is collected in a trough situated below a longitudinal slot at the bottom of the chamber. In both types of apparatus, after separation of the slurry the velocity of the steam is reduced to settle out remaining oil droplets and is then discharged to the atmosphere.

    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.

    A method of upgrading an oil feedstock by removing heteroatoms and/or one or more heavy metals from the oil feedstock composition. This method reacts the oil feedstock with an alkali metal and an upgradant hydrocarbon. The alkali metal reacts with a portion of the heteroatoms and/or one or more heavy metals to form an inorganic phase separable from the organic oil feedstock material. The upgradant hydrocarbon bonds to the oil feedstock material and increases the number of carbon atoms in the product. This increase in the number of carbon atoms of the product increases the energy value of the resulting oil feedstock.

    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.

    1984-04-24T23:59:59.000Z

    An in-situ oil shale retort is formed in a subterranean formation containing oil shale. The formation comprises at least one region of relatively richer oil shale and another region of relatively leaner oil shale. According to one embodiment, formation is excavated from within a retort site for forming at least one void extending horizontally across the retort site, leaving a portion of unfragmented formation including the regions of richer and leaner oil shale adjacent such a void space. A first array of vertical blast holes are drilled in the regions of richer and leaner oil shale, and a second array of blast holes are drilled at least in the region of richer oil shale. Explosive charges are placed in portions of the blast holes in the first and second arrays which extend into the richer oil shale, and separate explosive charges are placed in portions of the blast holes in the first array which extend into the leaner oil shale. This provides an array with a smaller scaled depth of burial (sdob) and closer spacing distance between explosive charges in the richer oil shale than the sdob and spacing distance of the array of explosive charges in the leaner oil shale. The explosive charges are detonated for explosively expanding the regions of richer and leaner oil shale toward the horizontal void for forming a fragmented mass of particles. Upon detonation of the explosive, greater explosive energy is provided collectively by the explosive charges in the richer oil shale, compared with the explosive energy produced by the explosive charges in the leaner oil shale, resulting in comparable fragmentation in both grades of oil shale.

    Geological and geophysical data from the federal offshore areas seaward of California, Oregon, and Washington (Pacific Outer Continental Shelf or OCS) are being used to identify petroleum plays for the Department of the Interior's National Assessment of Undiscovered Oil and Gas Resources project. Analysis of these data by a team of Minerals Management Service geo-scientists have led to the definition, delineation, and qualitative characterization of plays in six Pacific OCS assessment provinces: Pacific Northwest, Central California, Santa-Barbara-Ventura Basin, Los Angeles Basin, inner borderland, and other borderland. Plays are defined on the bases of reservoir rock stratigraphy, trap style, and hydrocarbon type. Each play is classified as established, frontier, or conceptual according to its discovery status and data availability. Preliminary analysis of the plays are complete and have been compiled in map and text formats by province. Plays are being further analyzed to characterize their quantitative attributatives such as numbers and sizes of undiscovered fields and geologic risk. Statistical evaluation to develop volumetric estimates of undiscovered oil and gas resources will be completed in late 1994. A discovery process modeling technique will be used to evaluate established plays in the Santa Maria and Santa Barbara-Ventura basins. Subjective modeling, based on estimated field-size distributions, will be applied to frontier and conceptual plays. Formal reports of the assessment results will be presented in 1995.

    The Crude Oil Futures presentation shows their concept of the quantity of oil possibly present (the combination of conventional demonstrated reserves plus undiscovered recoverable resources) within the areas outlined. The Crude Oil Futures is not as an exploration map but as a perspective on the distribution of world oil. The occurrence of oil is, after all, a function of particular geologic factors that are not everywhere present. Furthermore, large amounts of oil can occur only where the several necessary independent variables (geologic factors) combine optimally. In the Western Hemisphere, similar minimal crude oil futures are shown for North America and South America. This similarity is a reflection not of similar geology but rather of the fact that most of the oil has already been produced from North America, whereas South America as a whole (except for Venezuela) possesses a geology less likely to produce oil. In Europe, Africa, and Asia, four regions are dominant: the Middle East, Libya, North Sea, and west Siberia. Paleogeography and source rock distribution were keys to this distribution - the Middle East and Libya reflecting the Tethyan association, and the North Sea and west Siberia benefitting from the Late Jurassic marine transgression into geographic environments where ocean circulation was restricted by tectonic events.

    In the first year of this project, we have established our experimental and theoretical methodologies for studies of the catalytic decarboxylation process. We have developed both glass and stainless steel micro batch type reactors for the fast screening of various catalysts with reaction substrates of model carboxylic acid compounds and crude oil samples. We also developed novel product analysis methods such as GC analyses for organic acids and gaseous products; and TAN measurements for crude oil. Our research revealed the effectiveness of several solid catalysts such as NA-Cat-1 and NA-Cat-2 for the catalytic decarboxylation of model compounds; and NA-Cat-5{approx}NA-Cat-9 for the acid removal from crude oil. Our theoretical calculations propose a three-step concerted oxidative decarboxylation mechanism for the NA-Cat-1 catalyst.

    The removal of sulfur from Eastern oil shale (40 microns particle size) slurries in bioreactors by mixed microbial cultures was examined. A mixed culture that is able to remove the organic sulfur from model sulfur compounds presenting coal as well as a mixed culture isolated from oil shale enrichments were evaluated. The cultures were grown in aerobic fed-batch bioreactors where the oil shale served as the source of all nutrients except organic carbon. Glucose was added as an auxiliary carbon source. Microbial growth was monitored by plate counts, the pH was checked periodically, and oil shale samples were analyzed for sulfur content. Results show a 24% reduction in the sulfur content of the oil shale after 14 days. The settling characteristics of the oil shale in the bioreactors were examined in the presence of the microbes. Also, the mixing characteristics of the oil shale in the bioreactors were examined. 10 refs., 6 figs., 5 tabs.

Coastal sites will be additionally studied to determine ecological recovery of impacted wetland and open bay areas. The economic impact of existing and proposed effluent federal and state regulations will also be evaluated. The primary objectives of the project are to increase the base of scientific knowledge concerning (1) the fate and environmental effects of organics, trace metals, and NORM in water, sediment, and biota near several offshore oil and gas facilities; (2) the characteristics of produced water and produced sand discharges as they pertain to organics, trace metals, and NORM variably found in association with the discharges; (3) the recovery of four terminated produced water discharge sites located in wetland and high-energy open bay sites of coastal Louisiana and Texas; (4) the economic and energy supply impacts of existing and anticipated federal and state offshore and coastal discharge regulations; and (5) the catch, consumption and human use patterns of seafood species collected from coastal and offshore waters. Accomplishments for this period are described.

    Oil represents an obvious hazard for the coastal environment and studies on its impact on marine organisms are necessary. Solvent based oil dispersants constitute one of the most important means for removing oil from shores. Although recently new dispersants have been developed, which are much less toxic than the first ones, dispersants still remain toxic substances. Since in the case of oil pollution treatment, oils and detergents are acting in combination, a realistic approach of laboratory studies must also include the combined action of these substances on marine organisms. Although acute toxicity studies are very useful for the determination of the range of animal tolerance, other effects causing physiological alterations may be detrimental to a population's survival. This paper concerns research on the effects of an oil, an oil dispersant and of the mixture of oil and dispersant on a physiological process, the respiration of the brine shrimp Artemia salina.

The single and multiple ring hydroxyaromatic hydrocarbon compounds in a raw oil material are first deoxygenated to produce a deoxygenated oil material containing single and multiple ring aromatic compounds. Then, water is removed from the deoxygenated oil material. The next step is distillation to remove the single ring aromatic compouns as gasoline. In the third step, the multiple ring aromatics remaining in the deoxygenated oil material are cracked in the presence of hydrogen to produce a cracked oil material containing single ring aromatic compounds. Finally, the cracked oil material is then distilled to remove the single ring aromatics as gasoline.

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

    With the depletion of conventional crude oil reserves in the world, heavy oil and bitumen resources have great potential to meet the future demand for petroleum products. However, oil recovery from heavy oil and bitumen reservoirs is much more difficult than that from conventional oil reservoirs. This is mainly because heavy oil or bitumen is partially or completely immobile under reservoir conditions due to its extremely high viscosity, which creates special production challenges. In order to overcome these challenges significant efforts were devoted by Applied Research Center (ARC) at Florida International University and The Center for Energy Economics (CEE) at the University of Texas. A simplified model was developed to assess the density of the upgraded crude depending on the ratio of solvent mass to crude oil mass, temperature, pressure and the properties of the crude oil. The simplified model incorporated the interaction dynamics into a homogeneous, porous heavy oil reservoir to simulate the dispersion and concentration of injected CO2. The model also incorporated the characteristic of a highly varying CO2 density near the critical point. Since the major challenge in heavy oil recovery is its high viscosity, most researchers have focused their investigations on this parameter in the laboratory as well as in the field resulting in disparaging results. This was attributed to oil being a complex poly-disperse blend of light and heavy paraffins, aromatics, resins and asphaltenes, which have diverse behaviors at reservoir temperature and pressures. The situation is exacerbated by a dearth of experimental data on gas diffusion coefficients in heavy oils due to the tedious nature of diffusivity measurements. Ultimately, the viscosity and thus oil recovery is regulated by pressure and its effect on the diffusion coefficient and oil swelling factors. The generation of a new phase within the crude and the differences in mobility between the new crude matrix and the precipitate readily enables removal of asphaltenes. Thus, an upgraded crude low in heavy metal, sulfur and nitrogen is more conducive for further purification.

    A pilot-scale test to remove polar and non-polar organics from produced water was performed at a disposal facility in Farmington NM. We used surfactant-modified zeolite (SMZ) adsorbent beds and a membrane bioreactor (MBR) in combination to reduce the organic carbon content of produced water prior to reverse osmosis (RO). Reduction of total influent organic carbon (TOC) to 5 mg/L or less is desirable for efficient RO system operation. Most water disposed at the facility is from coal-bed gas production, with oil production waters intermixed. Up to 20 gal/d of produced water was cycled through two SMZ adsorbent units to remove volatile organic compounds (BTEX, acetone) and semivolatile organic compounds (e.g., napthalene). Output water from the SMZ units was sent to the MBR for removal of the organic acid component of TOC. Removal of inorganic (Mn and Fe oxide) particulates by the SMZ system was observed. The SMZ columns removed up to 40% of the influent TOC (600 mg/L). BTEX concentrations were reduced from the initial input of 70 mg/L to 5 mg/L by the SMZ and to an average of 2 mg/L after the MBR. Removal rates of acetate (input 120-170 mg/L) and TOC (input up to 45 mg/L) were up to 100% and 92%, respectively. The water pH rose from 8.5 to 8.8 following organic acid removal in the MBR; this relatively high pH was likely responsible for observed scaling of the MBR internal membrane. Additional laboratory studies showed the scaling can be reduced by metered addition of acid to reduce the pH. Significantly, organic removal in the MBR was accomplished with a very low biomass concentration of 1 g/L throughout the field trial. An earlier engineering evaluation shows produced water treatment by the SMZ/MBR/RO system would cost from $0.13 to $0.20 per bbl at up to 40 gpm. Current estimated disposal costs for produced water are $1.75 to $4.91 per bbl when transportation costs are included, with even higher rates in some regions. Our results suggest that treatment by an SMZ/MBR/RO system may be a feasible alternative to current methods for produced water treatment and disposal.

    Technology has produced more effective and efficient oil removal equipment for on-water cleanup in the past five years. Much of the innovation has been to increase recovery capacity to meet the planning volumes required to government regulations. However, more than 95 percent of the spills are relatively small. Large equipment, often requiring large platforms, is not very useful and is difficult/expensive to operate on small spills. In addition, damage from spills results when oil impacts shorelines. The emphasis on spill response should address the ability of the equipment to remove oil in a nearshore environment. Clean Seas has been attempting to address this need since the Avila Pipeline spill in 1992, in which a 180 barrel spill resulted in about $18 million damage/cleanup cost.

    Jordan and China have signed an agreement to develop oil shale processing technology that could lead to a 200 ton/day oil shale plant in Jordan. China will process 1200 tons of Jordanian oil shale at its Fu Shun refinery. If tests are successful, China could build the demonstration plant in Jordan's Lajjun region, where the oil shale resource is estimated at 1.3 billion tons. China plans to send a team to Jordan to conduct a plant design study. A Lajjun oil shale complex could produce as much as 50,000 b/d of shale oil. An earlier 500 ton shipment of shale is said to have yielded promising results.

    Micronized coal is removed from coal-bearing steam by spraying stabilized petroleum oil into the steam and directing the resultant stream at a separation surface on which a coal-oil slurry is deposited and collected. Apparatus includes conduits which direct the resultant stream downward into a housing and normal to a surface on which the slurry is deposited by impact forces. In additional apparatus disclosed, the resultant stream is directed from a horizontal conduit circumferentially along the interior wall of a horizontally disposed cylindrical chamber at the top of the chamber and the coal-oil slurry deposited on the wall by centrifugal force is collected in a trough situated below a longitudinal slot at the bottom of the chamber. In both types of apparatus, after separation of the slurry the velocity of the steam is reduced to settle out remaining oil droplets and is then discharged to the atmosphere.

    California is unique in the United States because it has the largest heavy oil (10{degrees} to 20{degrees}API gravity) resource, estimated to be in excess of 40 billion barrels. Of the current 941,543 barrels/day of oil produced in California (14% of the U.S. total), 70% or 625,312 barrels/day is heavy oil. Heavy oil constituted only 20% of California`s oil production in the early 1940s, but development of thermal oil production technology in the 1960s allowed the heavy industry to grow and prosper to the point where by the mid-1980s, heavy oil constituted 70% of the state`s oil production. Similar to the rest of the United States, light oil production in the Los Angeles Basin, Coastal Region, and San Joaquin Valley peaked and then declined at different times throughout the past 30 years. Unlike other states, California developed a heavy oil industry that replaced declining light oil production and increased the states total oil production, despite low heavy oil prices, stringent environmental regulations and long and costly delays in developing known oil resources. California`s deep conversion refineries process the nation`s highest sulfur, lowest API gravity crude to make the cleanest transportation fuels available. More efficient vehicles burning cleaner reformulated fuels have significantly reduced the level of ozone precursors (the main contributor to California`s air pollution) and have improved air quality over the last 20 years. In a state where major oil companies dominate, the infrastructure is highly dependent on the 60% of ANS production being refined in California, and California`s own oil production. When this oil is combined with the small volume of imported crude, a local surplus of marketed oil exists that inhibits exploitation of California`s heavy oil resources. As ANS production declines, or if the export restrictions on ANS sales are lifted, a window of opportunity develops for increased heavy oil production.

    On Aug. 2, 1990, Iraqi forces invaded Kuwait and triggered one of the most severe crises in the world's oil supplies since World War II. Within a few days of the invasion, Iraqi and Kuwaiti oil exports were embargoed, and almost 4.6 million b/d oil of production was removed from world markets. This shortfall amounted to about 20% of total Organization of Petroleum Exporting Countries production at the time and could have proven disastrous to the world's industrial and financial well-being. However, there was no disruption to the major economies of the world. This paper reports that the primary reason for the cushioning of this impact was the massive expansion in production undertaken by Saudi Arabian Oil Co. (Saudi Aramco).

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

    SciTech Connect (OSTI)

    Greene, D.L.

    2003-11-14T23:59:59.000Z

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

    In the past three years, we followed the work plan as we suggested in the proposal and made every efforts to fulfill the project objectives. Based on our large amount of creative and productive work, including both of experimental and theoretic aspects, we received important technical breakthrough on naphthenic acid removal process and obtained deep insight on catalytic decarboxylation chemistry. In detail, we established an integrated methodology to serve for all of the experimental and theoretical work. Our experimental investigation results in discovery of four type effective catalysts to the reaction of decarboxylation of model carboxylic acid compounds. The adsorption experiment revealed the effectiveness of several solid materials to naphthenic acid adsorption and acidity reduction of crude oil, which can be either natural minerals or synthesized materials. The test with crude oil also received promising results, which can be potentially developed into a practical process for oil industry. The theoretical work predicted several possible catalytic decarboxylation mechanisms that would govern the decarboxylation pathways depending on the type of catalysts being used. The calculation for reaction activation energy was in good agreement with our experimental measurements.

    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.

    Fast pyrolysis offers a relatively low cost method of processing biomass to produce a liquid product that has the potential for conversion to several types of liquid fuels. The liquid product of fast pyrolysis, known as pyrolysis oil or bio-oil, contains a high oxygen content primarily in the form of water, carboxylic acids, phenols, ketones and aldehydes. These oils are typically very acidic with a Total Acid Number that is often in the range of 50 to 100, and previous studies have shown this material to be quite corrosive to common structural materials. Removal of at least some of the oxygen and conversion of this oil to a more useful product that is considerably less corrosive can be accomplished through a hydrogenation process. The product of such a treatment is considered to have the potential for blending with crude oil for processing in petroleum refineries. Corrosion studies and chemical analyses have been conducted using as produced bio-oil samples as well as samples that have been subjected to different levels of oxygen removal. Chemical analyses show treatment affected the concentrations of carboxylic acids contained in the oil, and corrosion studies showed a positive benefit of the oxygen removal. Results of these studies will be presented in this paper.

    World oil prices in Annual Energy Outlook 2005 are set in an environment where the members of OPEC (Organization of the Petroleum Exporting Countries) are assumed to act as the dominant producers, with lower production costs than other supply regions or countries. Non-OPEC oil producers are assumed to behave competitively, producing as much oil as they can profitability extract at the market price for oil. As a result, the OPEC member countries will be able effectively to set the price of oil when they can act in concert by varying their aggregate production. Alternatively, OPEC members could target a fixed level of production and let the world market determine the price.

    A coal combustor/gasifier is disclosed which produces a low or medium combustion gas for further combustion in modified oil or gas fired furnaces or boilers. Two concentric shells define a combustion volume within the inner shell and a plenum between them through which combustion air flows to provide regenerative cooling of the inner shell for dry ash operation. A fuel flow and a combustion air flow having opposed swirls are mixed and burned in a mixing-combustion portion of the combustion volume and the ash laden combustion products flow with a residual swirl into an ash separation region. The ash is cooled below the fusion temperature and is moved to the wall by centrifugal force where it is entrained in the cool wall boundary layer. The boundary layer is stabilized against ash re-entrainment as it is moved to an ash removal annulus by a flow of air from the plenum through slots in the inner shell, and by suction on an ash removal skimmer slot.

    Studies dealing with the interactions between extremophilic microorganisms and crude oils have led to the identification of biocatalysts which through multiple biochemical reactions catalyze desulfurization, denitrogenation, and demetalation reactions in oils. Concurrently, the oils are also converted to lighter oils. These complex biochemical reactions have served as models in the development of the crude oil bioconversion technology to be applied prior to the treatment of oils by conventional chemical processes. In practical terms, this means that the efficiency of the existing technology is being enhanced. For example, the recently introduced additional regulation for the emission of nitrogen oxides in some states restricts further the kinds of oils that may be used in burners. The biocatalysts being developed in this laboratory selectively interact with nitrogen compounds, i.e. basic and neutral types present in the oil and, hence, affect the fuel NOx production. This, in turn, has a cost-efficient influence on the processed oils and their consumption. In this paper, these cost-efficient and beneficial effects will be discussed in terms of produced oils, the lowering of sulfur and nitrogen contents, and the effect on products, as well as the longevity of catalysts due to the removal of heteroatoms and metal containing compounds found in crudes.

    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

    In August of 1998 the Z facility leaked approximately 150 gallons of deionized water into the dielectric oil of the Energy Storage Section (ESS). After processing the oil to remove existing particulate and free water the dielectric breakdown strength increased from the mid 20kV range to values in excess of 40 kV. 40 kV is above historical operating levels of about 35 kV. This, however, was not enough to allow 90 kV charging of the Marx Generators in the ESS. Further analysis of the oil showed dissolved water at a saturated level (70 - 80 ppm) and some residual particulate contamination smaller than 3 microns. The dissolved water and particulate combination was preventing the 90 kV charging of the Marx Generators in the ESS. After consulting with the oil industry it was determined that nitrogen sparging could be used to remove the dissolved water. Further particulate filtering was also conducted. After approximately 20 hours of sparging the water content in the ESS was reduced to 42 ppm which enabled Marx charging to 90 kV.

    UOP Sulfox technology successfully removed 500 ppM hydrogen sulfide from simulated mixed phase geothermal waters. The Sulfox process involves air oxidation of hydrogen sulfide using a fixed catalyst bed. The catalyst activity remained stable throughout the life of the program. The product stream composition was selected by controlling pH; low pH favored elemental sulfur, while high pH favored water soluble sulfate and thiosulfate. Operation with liquid water present assured full catalytic activity. Dissolved salts reduced catalyst activity somewhat. Application of Sulfox technology to geothermal waters resulted in a straightforward process. There were no requirements for auxiliary processes such as a chemical plant. Application of the process to various types of geothermal waters is discussed and plans for a field test pilot plant and a schedule for commercialization are outlined.

    Oilfield production is often hindered by asphaltene precipitation which tends to fill the pores of the reservoir rocks and plug the wellbore tubing as well as the other auxiliary equipment used during crude oil recovery. Several remedies to remove these deposits have been proposed and patented but the injection of aromatic solvents such as toluene and light petroleum distillates is normally preferred. Previous studies with a number of pure aromatic hydrocarbons have shown that the solvent capacity of these molecules may be very different and that the degree of condensation plays an important role. In this regard, tetralins and naphthalenes are superior to alkylbenzenes. However, because the use of pure compounds is not economically feasible, the authors examined various industrial streams and the authors correlated their chemical composition to the solvent capacity. This work allowed the identification of the pseudo-components whose relative concentration is crucial for evaluating the solvent performances. Based on these data, the authors were able to find new products with ideal characteristics. The efficiency of one of these products was confirmed by the analysis of the data obtained when using this new solvent to remove asphaltene in damaged wells of an Italian field.

    The present invention relates to a method of removing polychlorinated biphenyls from soil. The polychlorinated biphenyls are extracted from the soil by employing a liquid organic solvent dispersed in water in the ratio of about 1:3 to 3:1. The organic solvent includes such materials as short-chain hydrocarbons including kerosene or gasoline which are immiscible with water and are nonpolar. The organic solvent has a greater affinity for the PCB's than the soil so as to extract the PCB's from the soil upon contact. The organic solvent phase is separated from the suspended soil and water phase and distilled for permitting the recycle of the organic solvent phase and the concentration of the PCB's in the remaining organic phase. The present process can be satisfactorily practiced with soil containing 10 to 20% petroleum-based oils and organic fluids such as used in transformers and cutting fluids, coolants and the like which contain PCB's. The subject method provides for the removal of a sufficient concentration of PCB's from the soil to provide the soil with a level of PCB's within the guidelines of the Environmental Protection Agency.

    The Contaminated Sediment Removal Program (CSRP) of Environment Canada was founded in November 1990 following a request from the Great Lakes Cleanup Fund to the Environmental Protection Service-Ontario Region to provide the leadership in the identification of removal technologies and procedures for contaminated sediments in the Great Lakes. Following a request for proposal issued by the CSRP, proposals were received from vendors of innovative sediment removal technologies to conduct contaminated sediment removal demonstrations in different Areas of Concern (AOCs) on the Canadian side of the Great Lakes. In 1992, the CSRP conducted the demonstration of two innovative sediment removal technologies at three different sites. The Cable Arm 100E clamshell bucket was demonstrated in Toronto and Hamilton Harbors, while the Pneuma Pump was demonstrated in Collingwood Harbor. Those three demonstrations led to the first Canadian commercial applications of the Cable Arm 100E clamshell bucket in Pickering, Ontario, and of the Pneuma Pump in Collingwood, Ontario.

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

    Two major oil families are identified in the West Siberian basin. Twenty-six of 32 analyzed oils occur in Jurassic and cretaceous reservoirs and are derived from anoxic marine Upper Jurassic Bazhenov source rock. These oils are widely distributed both north and immediately south of the Ob River, and their biomarker ratios indicate a wide range of source rock thermal maturity from early to middle oil window (Van-Egan, Russkoye, Samotlor, Sovninsko-Sovyet, Olyenye, Ozynornoye, and Kogolym), to peak oil window (Srednekhulym, Yem-Yegov, Vostochno-Surgut, Khokhryakov, Fedorov, and Urengoi), to late oil window (Salym). Some of these oils have been mildly (e.g., Fedorov 75) to heavily (e.g., Russkoye) biodegraded in the reservoir. The Bazhenov-sourced oils show different compositions that support regional variations of organic facies in the source rock. Six nonbiodegraded, highly mature oils show geochemical characteristics that suggest they were derived from clastic-rich lacustrine or nearshore marine source rocks dominated by terrigenous higher plant input like those in the Lower to Middle Jurassic Tyumen Formation, although no correlation was observed between the oils and single rock sample (Yem-Yegov 15) from the formation. The six oils occur in the Tyumen (Taitym, Geologiche, and Cheremshan) and fractured basement/Paleozoic (Gerasimov, Yagyl Yakh, and Verchnekombar) reservoirs in positions readily accessible to any oil migrating from the Tyumen source rock. For example, at the Gerasimov locations, the Tyumen Formation lies unconformably on weathered basement-Paleozoic reservoir rocks. Most of the probable Tyumen-sourced oils are from south of the Ob River, but the occurrence of Geologiche oil to the north suggests that related oils may be widespread in the basin.

    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.

    The Oil Pollution Act of 1990 ( OPA'') and an even more problematic array of State pollution laws have raised the cost, and risk, of carrying oil into and out of the US. This report, prepared under contract to the US Department of energy's Office of Domestic and International Policy, examines the impact of Federal and State oil spill legislation on the tanker market. It reviews the role of marine transportation in US oil supply, explores the OPA and State oil spill laws, studies reactions to OPA in the tanker and tank barge industries and in related industries such as insurance and ship finance, and finally, discusses the likely developments in the years ahead. US waterborne oil imports amounted to 6.5 million B/D in 1991, three-quarters of which was crude oil. Imports will rise by almost 3 million B/D by 2000 according to US Department of energy forecasts, with most of the crude oil growth after 1995. Tanker demand will grow even faster: most of the US imports and the increased traffic to other world consuming regions will be on long-haul trades. Both the number of US port calls by tankers and the volume of offshore lightering will grow. Every aspect of the tanker industry's behavior is affected by OPA and a variety of State pollution laws.

    This study addresses the issue of oil removal from water using hydrophilic porous membranes. The effective separation of oil-in-water dispersions involves high flux of water through the membrane and, at the same time, high rejection rate of the oil phase. The effects of transmembrane pressure and crossflow velocity on rejection of oil droplets and thin oil films by pores of different cross-section are investigated numerically by solving the Navier-Stokes equation. We found that in the absence of crossflow, the critical transmembrane pressure, which is required for the oil droplet entry into a circular pore of a given surface hydrophilicity, agrees well with analytical predictions based on the Young-Laplace equation. With increasing crossflow velocity, the shape of the oil droplet is strongly deformed near the pore entrance and the critical pressure of permeation increases. We determined numerically the phase diagram for the droplet rejection, permeation, and breakup depending of the transmembrane pressure and...

    The purpose of this report is to define the objectives of the Oil and Gas Supply Model (OGSM), to describe the model`s basic approach, and to provide detail on how the model works. This report is intended as a reference document for model analysts, users, and the public. Projected production estimates of US crude oil and natural gas are based on supply functions generated endogenously within National Energy Modeling System (NEMS) by the OGSM. OGSM encompasses domestic crude oil and natural gas supply by both conventional and nonconventional recovery techniques. Nonconventional recovery includes enhanced oil recovery (EOR), and unconventional gas recovery (UGR) from tight gas formations, Devonian/Antrim shale and coalbeds. Crude oil and natural gas projections are further disaggregated by geographic region. OGSM projects US domestic oil and gas supply for six Lower 48 onshore regions, three offshore regions, and Alaska. The general methodology relies on forecasted profitability to determine exploratory and developmental drilling levels for each region and fuel type. These projected drilling levels translate into reserve additions, as well as a modification of the production capacity for each region. OGSM also represents foreign trade in natural gas, imports and exports by entry region. Foreign gas trade may occur via either pipeline (Canada or Mexico), or via transport ships as liquefied natural gas (LNG). These import supply functions are critical elements of any market modeling effort.

    This paper reports on Gabon's largest oil field, Rabi Kounga, and a flurry of smaller reservoirs which have boosted production to 300,000 bopd. Regional geology is so complex that it generates a large discovery only once every twenty years, and operators come and go due to low discovery ratios, following market ups and downs. A hard core four remain: Elf first, Shell, British Gas, which bought Tenneco, and Amoco. Shell's Rabi Kounga discovery, which stretches from shore to shelf, boosted exploration and renewed interest for onshore licenses. The low discovery rate, however, reflects the complexity of Gabonese basins.

    Oil shale is undoubtedly an excellent energy source that has great abundance and world-wide distribution. Oil shale industries have seen ups and downs over more than 100 years, depending on the availability and price of conventional petroleum crudes. Market forces as well as environmental factors will greatly affect the interest in development of oil shale. Besides competing with conventional crude oil and natural gas, shale oil will have to compete favorably with coal-derived fuels for similar markets. Crude shale oil is obtained from oil shale by a relatively simple process called retorting. However, the process economics are greatly affected by the thermal efficiencies, the richness of shale, the mass transfer effectiveness, the conversion efficiency, the design of retort, the environmental post-treatment, etc. A great many process ideas and patents related to the oil shale pyrolysis have been developed; however, relatively few field and engineering data have been published. Due to the vast heterogeneity of oil shale and to the complexities of physicochemical process mechanisms, scientific or technological generalization of oil shale retorting is difficult to achieve. Dwindling supplied of worldwide petroleum reserves, as well as the unprecedented appetite of mankind for clean liquid fuel, has made the public concern for future energy market grow rapidly. the clean coal technology and the alternate fuel technology are currently of great significance not only to policy makers, but also to process and chemical researchers. In this book, efforts have been made to make a comprehensive text for the science and technology of oil shale utilization. Therefore, subjects dealing with the terminological definitions, geology and petrology, chemistry, characterization, process engineering, mathematical modeling, chemical reaction engineering, experimental methods, and statistical experimental design, etc. are covered in detail.

    We have observed thin film removal from glass substrates after the irradiation of Ni films with femtosecond laser pulses in air. It was found that the material removal threshold and laser-induced morphology are dependent on film thickness. With decreasing thickness, material removal transitions from intra-film separation to removal at the Ni-glass interface. The Gaussian energy distribution of the laser pulse allows for intra-film separation in the annular region of the crater and interface separation in the center. We propose a model to explain these data as well as the observed increased surface roughness in the interfacial removal regions.

    UOP LLC, a Honeywell Company, assembled a comprehensive team for a two-year project to demonstrate innovative methods for the stabilization of pyrolysis oil in accordance with DOE Funding Opportunity Announcement (FOA) DE-PS36-08GO98018, Biomass Fast Pyrolysis Oil (Bio-oil) Stabilization. In collaboration with NREL, PNNL, the USDA Agricultural Research Service (ARS), Pall Fuels and Chemicals, and Ensyn Corporation, UOP developed solutions to the key technical challenges outlined in the FOA. The UOP team proposed a multi-track technical approach for pyrolysis oil stabilization. Conceptually, methods for pyrolysis oil stabilization can be employed during one or both of two stages: (1) during the pyrolysis process (In Process); or (2) after condensation of the resulting vapor (Post-Process). Stabilization methods fall into two distinct classes: those that modify the chemical composition of the pyrolysis oil, making it less reactive; and those that remove destabilizing components from the pyrolysis oil. During the project, the team investigated methods from both classes that were suitable for application in each stage of the pyrolysis process. The post processing stabilization effort performed at PNNL is described in this report. The effort reported here was performed under a CRADA between PNNL and UOP, which was effective on March 13, 2009, for 2 years and was subsequently modified March 8, 2011, to extend the term to December 31, 2011.

    Commercial processing of oil shale is currently being carried out in two countries, these being Manchuria and Estonia. Germany, Israel, Australia, Brazil and the United States are planning commercial development of oil shale during the 1980's. In the United States, developers currently pursuing production facilities in the Piceance Basin in Colorado are the Union Oil Company; Colony Development Company, now owned by Tosco and Exxon; Occidental Oil Shale Inc.; The Rio Blanco Shale Company (Amoco and Gulf) CA Tract; The Cathedral Bluff's Oil Shale Company (Oxy and Tenneco) at CB tract; The Anvil Points Bureau of Mines Site under the direction of DOE which has been leased to the Paraho Development Company to optimize their process; and Superior Oil. Superior Oil plans to recover Negcolite and Dowsonite that are associated with their oil shale. The processes used by these companies are described briefly. These are the Union B process, Tosco II process, Paraho process, and Occidental process. It is estimated that between 400,000 to 500,000 barrels per day (63,600 to 79,500 m/sup 3//day) production would be achieved by 1990 if all of the effects on the infrastructure are planned for and constructed in an orderly manner.

    First Article Tests of a stabilization method for greater than 260 mg mercury/kg oil were performed under a treatability study. This alternative treatment technology will address treatment of U.S. Department of Energy (DOE) organics (mainly used pump oil) contaminated with mercury and other heavy metals. Some of the oil is also co-contaminated with tritium, other radionuclides, and hazardous materials. The technology is based on contacting the oil with a sorbent powder (Self-Assembled Mercaptan on Mesoporous Support, SAMMS), proven to adsorb heavy metals, followed by stabilization of the oil/powder mixture using a stabilization agent (Nochar N990). Two variations of the treatment technology were included in the treatability study. The SAMMS (Self-Assembled Mercaptan on Mesoporous Silica) technology was developed by the Pacific Northwest National Laboratory for removal and stabilization of RCRA metals (i.e., lead, mercury, cadmium, silver, etc.) and for removal of mercury from organic solvents [1]. The SAMMS material is based on self-assembly of functionalized monolayers on mesoporous oxide surfaces. The unique mesoporous oxide supports provide a high surface area, thereby enhancing the metal-loading capacity. SAMMS material has high flexibility in that it binds with different forms of mercury, including metallic, inorganic, organic, charged, and neutral compounds [1] The material removes mercury from both organic wastes, such as pump oils, and from aqueous wastes. Mercury-loaded SAMMS not only passes TCLP tests, but also has good long-term durability as a waste form because: (1) the covalent binding between mercury and SAMMS has good resistance in ion-exchange, oxidation, and hydrolysis over a wide pH range and (2) the uniform and small pore size of the mesoporous silica prevents bacteria from solubilizing the bound mercury. Nochar's N990 Petrobond (Nochar, Inc., Indianapolis, IN) is an oil stabilization agent, specifically formulated for stabilizing vacuum pump oil, which has fewer volatile organics than many other oils. This material is a non-uniform granular powder that resembles ground Styrofoam plastics. This material has previously been used by itself and in combination with SAMMS to stabilize oil containing low levels of mercury {approx}50 mg/kg in surrogate waste studies [2].

    This paper describes the removal and disposal of the large components from Maine Yankee Atomic Power Plant. The large components discussed include the three steam generators, pressurizer, and reactor pressure vessel. Two separate Exemption Requests, which included radiological characterizations, shielding evaluations, structural evaluations and transportation plans, were prepared and issued to the DOT for approval to ship these components; the first was for the three steam generators and one pressurizer, the second was for the reactor pressure vessel. Both Exemption Requests were submitted to the DOT in November 1999. The DOT approved the Exemption Requests in May and July of 2000, respectively. The steam generators and pressurizer have been removed from Maine Yankee and shipped to the processing facility. They were removed from Maine Yankee's Containment Building, loaded onto specially designed skid assemblies, transported onto two separate barges, tied down to the barges, th en shipped 2750 miles to Memphis, Tennessee for processing. The Reactor Pressure Vessel Removal Project is currently under way and scheduled to be completed by Fall of 2002. The planning, preparation and removal of these large components has required extensive efforts in planning and implementation on the part of all parties involved.

    EPA defines used oil as any oil that has been refined from crude oil, or any synthetic oil, that has been used and as a result of such use is contaminated by physical or chemical impurities. 1 EPA’s criteria for used oil: • Origin: Used oil must have been refined from crude oil or made from synthetic materials (i.e., derived from coal, shale, or polymers). Examples of crude-oil derived oils and synthetic oils are motor oil, mineral oil, laminating surface agents, and metal working oils. Thus, animal and vegetable oils are not included. Bottom clean-out from virgin fuel oil storage tanks or virgin oil recovered from a spill, as well as products solely used as cleaning agents or for their solvent properties, and certain petroleum-derived products such as antifreeze and kerosene are also not included. Use: The oil must have been used as a lubricant, coolant, heat (non-contact) transfer fluid, hydraulic fluid, heat transfer fluid or for a similar use. Lubricants include, but are not limited to, used motor oil, metal working lubricants, and emulsions. An example of a hydraulic fluid is transmission fluid. Heat transfer fluids can be materials such as coolants, heating media, refrigeration oils, and electrical insulation oils. Authorized states or regions determine what is considered a “similar use ” on a site-specific basis according to whether the material is used and managed in a manner consistent with Part 279 (e.g., used as a buoyant). Contaminants: The used oil must be contaminated by physical (e.g., high water content, metal shavings, or dirt) or chemical (e.g., lead, halogens, solvents or other hazardous constituents) impurities as a result of use. 2.

    A method for removing actinide contaminants (uranium and thorium) from the spent salt of a molten salt oxidation (MSO) reactor is described. Spent salt is removed from the reactor and analyzed to determine the contaminants present and the carbonate concentration. The salt is dissolved in water, and one or more reagents are added to precipitate the thorium as thorium oxide and/or the uranium as either uranium oxide or as a diuranate salt. The precipitated materials are filtered, dried and packaged for disposal as radioactive waste. About 90% of the thorium and/or uranium present is removed by filtration. After filtration, salt solutions having a carbonate concentration >20% can be dried and returned to the reactor for re-use. Salt solutions containing a carbonate concentration <20% require further clean-up using an ion exchange column, which yields salt solutions that contain less than 0.1 ppm of thorium or uranium.

    In Macomb Township of Macomb County, southeast Michigan, is found a sinuous normal fault extending along a N82[degrees]W strike, from end to end only 6 mi long, but with more than 260 ft of maximum displacement at the Trenton level. Through about 3 mi of its midsection extent, the main fault is paired with another normal fault with opposite displacement sense, forming a very narrow graben. The timing of development of this divergent wrench feature coincides with Caledonian tectonic activity, a period of intense structural disturbance and regional subsidence throughout the Michigan basin. The fault appears to cut no higher than A[sub 1] Carbonate, although relationships are obscured by subsequent dissolution of more than 500 ft of Salina A[sub 1], A[sub 2], B, D, and F salts along and beyond the trace of the fault. Collapse of interbedded carbonates and shales is evident, although the apparent lack of brecciation indicates salt removal was not rapid. Further, salt removal proceeded throughout the Devonian, producing dramatic compensatory thickening in overlying units. The development of this large feature in prime Niagaran reef territory may have prevented the discovery of reefs by obscuring what is otherwise well-known stratigraphy and seismic signature. The presence of oil production in dolomitized fracture zones in the Trenton/Black River rocks of nearby Ontario may point to similar potential yet remaining along the Macomb faulted trend.

    Phenolic oils were produced from fast pyrolysis of two different biomass feedstocks, red oak and corn stover and evaluated in hydroprocessing tests for production of liquid hydrocarbon products. The phenolic oils were produced with a bio-oil fractionating process in combination with a simple water wash of the heavy ends from the fractionating process. Phenolic oils derived from the pyrolysis of red oak and corn stover were recovered with yields (wet biomass basis) of 28.7 wt% and 14.9 wt%, respectively, and 54.3% and 58.6% on a carbon basis. Both precious metal catalysts and sulfided base metal catalyst were evaluated for hydrotreatingmore »the phenolic oils, as an extrapolation from whole bio-oil hydrotreatment. They were effective in removing heteroatoms with carbon yields as high as 81% (unadjusted for the 90% carbon balance). There was nearly complete heteroatom removal with residual O of only 0.4% to 5%, while N and S were reduced to less than 0.05%. Use of the precious metal catalysts resulted in more saturated products less completely hydrotreated compared to the sulfided base metal catalyst, which was operated at higher temperature. The liquid product was 42-52% gasoline range molecules and about 43% diesel range molecules. Particulate matter in the phenolic oils complicated operation of the reactors, causing plugging in the fixed-beds especially for the corn stover phenolic oil. This difficulty contrasts with the catalyst bed fouling and plugging, which is typically seen with hydrotreatment of whole bio-oil.

    This Oil Bypass Filter Technology Evaluation quarterly report (January– March 2005) details the ongoing fleet evaluation of oil bypass filter technologies being conducted by the Idaho National Laboratory (INL) for the U.S. Department of Energy’s FreedomCAR & Vehicle Technologies Program. Eleven INL fourcycle diesel-engine buses and six INL Chevrolet Tahoes with gasoline engines are equipped with oil bypass filter systems. Eight of the buses and the six Tahoes are equipped with oil bypass filters from the puraDYN Corporation; the remaining three buses are equipped with oil bypass filters from Refined Global Solutions. Both the puraDYN and Refined Global Solutions bypass filters have a heating chamber to remove liquid contaminates from the oil. During the January to March 2005 reporting quarter, the eleven diesel engine buses traveled 97,943 miles. As of March 31, 2005, the buses had accumulated 744,059 total test miles. During this quarter, four regularly scheduled 12,000-mile bus servicings were performed. The full-flow and bypass oil filters were changed and oil analysis samples were taken for the four buses. Bus 73446 had its oil changed due to a low total base number value. Bus 73450 had a major engine failure at the beginning of the quarter when one of its pushrods and valves were damaged. Buses 73432 and 73433 were removed from the bypass filter evaluation project and placed into the INL Diesel Engine Idling Wear-Rate Evaluation Test. While a total of nine oil changes on the INL buses occurred during the past 29 months, 53 oil changes have been avoided by using the oil bypass filters. The 53 avoided oil changes equates to 1,855 quarts (464 gallons) of new oil not consumed and 1,855 quarts of waste oil not generated. Therefore, over 85% of the oil normally required for oil-changes was not used, and, consequently, the evaluation achieved a greater than 85% reduction in the amount of waste oil normally generated by the buses. The six Tahoe test vehicles traveled 40,700 miles, and as of March 31, 2005, the Tahoes had accumulated 231,428 total test miles.

    Polymeric materials have been prevalent in our everyday lives for quite a long time. Most of today's polymeric materials are derived from nonrenewable petroleum-based feedstocks. Instabilities in the regions where petroleum is drilled, along with an increased demand in petroleum, have driven the price of crude oil to record high prices. This, in effect, increases the price of petroleum-based polymeric materials, which has caused a heightened awareness of renewable alternatives for polymeric feedstocks. Cellulose, starch, proteins and natural oils have all been examined as possible polymeric feedstocks. Natural oils are commercially available on a large scale and are relatively cheap. It is projected that the U.S. alone will produce 21 billion pounds of soybean oil in the period 2008/2009. Natural oils also have the advantages of inherent biodegradability, low toxicity, high purity and ready availability. Most natural oils possess a triglyceride structure as shown in Figure 1. Most natural oils have a unique distribution of fatty acid side chains, along with varying degrees of unsaturation per triglyceride. Common fatty acid side chains in naturally occurring oils are palmitic acid (C16:0), a 16 carbon fatty acid with no unsaturation; stearic acid (C18:0), an 18 carbon fatty acid with no unsaturation; oleic acid (C18:1), an 18 carbon fatty acid with one double bond; linoleic acid (C18:2), an 18 carbon fatty acid with two double bonds; and linolenic acid (C18:3), an 18 carbon fatty acid with three double bonds. Of course, there are other fatty acids with varying degrees of unsaturation, but their abundance is usually minimal. All of the unsaturated fatty acids mentioned have naturally occurring cis double bonds, which is common for most unsaturated fatty acids. In addition, the afore mentioned fatty acids have the first double bond at the position of carbon 9 (C9), followed by carbon 12 (C12), if there are two degrees of unsaturation, then at carbon 15 (C15), if there are three degrees of unsaturation. In addition, the double bonds are not in conjugation. Table 1 gives the fatty acid make-up of linseed oil. It can be seen that linseed oil has an average of 6.0 double bonds per triglyceride. Its fatty acid content consists of 5.4% palmitic acid (C16:0), 3.5% stearic acid (C18:0), 19% oleic acid (C18:1), 24 % linoleic acid (C18:2) and 47% linolenic (C18:3). Table 1 also gives the fatty acid composition and varying degrees of unsaturation for various other naturally-occurring natural vegetable oils. The regions of unsaturation in natural oils allow for interesting polymer chemistry to take place. Some of this interesting polymer science, however, involves chemical modification of the regions of unsaturation. Acrylated epoxidized soybean oil (AESO) is prepared by epoxidation of the double bonds, followed by ring opening with acrylic acid. The resulting oil has both acrylate groups and hydroxyl groups. Wool and colleagues have further reacted the hydroxyl groups within the oil with maleic anhydride to produce maleated acrylated epoxidized soybean oil (MAESO). The MAESO has been copolymerized with styrene free radically to produce promising thermosetting sheet molding resins. Petrovi? and co-workers have directly ring opened the epoxidized oil to produce polyols that produce promising polyurethanes through condensation polymerization with diisocyanates. Our group's work initially focused on direct cationic copolymerization of the double bonds or conjugated double bonds of natural oils with monomers, such as styrene and divinylbenzene, to produce promising thermosetting resins. The only modification of the oils that was carried out in these studies was conjugation of the double bonds to enhance the reactivity of the oil. This work has been expanded recently with the incorporation of glass fiber to produce promising composites. We have also explored thermal polymerization techniques to make novel thermosets. This dissertation is divided into four chapters. The first chapter discusses the synthesis and characterization of biobased

    A system is provided for utilizing fines of carbonaceous materials such as particles or pieces of oil shale of about one-half inch or less diameter which are rejected for use in some conventional or prior surface retorting process, which obtains maximum utilization of the energy content of the fines and which produces a waste which is relatively inert and of a size to facilitate disposal. The system includes a cyclone retort (20) which pyrolyzes the fines in the presence of heated gaseous combustion products, the cyclone retort having a first outlet (30) through which vapors can exit that can be cooled to provide oil, and having a second outlet (32) through which spent shale fines are removed. A burner (36) connected to the spent shale outlet of the cyclone retort, burns the spent shale with air, to provide hot combustion products (24) that are carried back to the cyclone retort to supply gaseous combustion products utilized therein. The burner heats the spent shale to a temperature which forms a molten slag, and the molten slag is removed from the burner into a quencher (48) that suddenly cools the molten slag to form granules that are relatively inert and of a size that is convenient to handle for disposal in the ground or in industrial processes.

The separator is provided with a downwardly extending skirt to contain the oil/gas which floats or is forced upward into a dome wherein the gas is separated from the oil/water, with the gas being flared (burned) at the top of the dome, and the oil is separated from water and pumped to a point of use. Since the density of oil is less than that of water it can be easily separated from any water entering the dome.

    The Oil Pollution Act of 1990 (``OPA``) and an even more problematic array of State pollution laws have raised the cost, and risk, of carrying oil into and out of the US. This report, prepared under contract to the US Department of energy`s Office of Domestic and International Policy, examines the impact of Federal and State oil spill legislation on the tanker market. It reviews the role of marine transportation in US oil supply, explores the OPA and State oil spill laws, studies reactions to OPA in the tanker and tank barge industries and in related industries such as insurance and ship finance, and finally, discusses the likely developments in the years ahead. US waterborne oil imports amounted to 6.5 million B/D in 1991, three-quarters of which was crude oil. Imports will rise by almost 3 million B/D by 2000 according to US Department of energy forecasts, with most of the crude oil growth after 1995. Tanker demand will grow even faster: most of the US imports and the increased traffic to other world consuming regions will be on long-haul trades. Both the number of US port calls by tankers and the volume of offshore lightering will grow. Every aspect of the tanker industry`s behavior is affected by OPA and a variety of State pollution laws.

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

    2000-11-09T23:59:59.000Z

    Over one thousand gallons of tritiated oil, at various contamination levels, are stored in the Main Hill Tritium Facility at the Miamisburg Environmental Management Project (MEMP), commonly referred to as Mound Site. This tritiated oil is to be characterized for hazardous materials and radioactive contamination. Most of the hazardous materials are expected to be in the form of heavy metals, i.e., mercury, silver, lead, chromium, etc, but transuranic materials and PCBs could also be in some oils. Waste oils, found to contain heavy metals as well as being radioactively contaminated, are considered as mixed wastes and are controlled by Resource Conservation and Recovery Act (RCRA) regulations. The SAMMS (Self-Assembled Mercaptan on Mesoporous Silica) technology was developed by the Pacific Northwest National Laboratory (PNNL) for removal and stabilization of RCRA metals (i.e., lead, mercury, cadmium, silver, etc.) and for removal of mercury from organic solvents. The SAMMS material is based on self-assembly of functionalized monolayers on mesoporous oxide surfaces. The unique mesoporous oxide supports provide a high surface area, thereby enhancing the metal-loading capacity. SAMMS material has high flexibility in that it binds with different forms of mercury, including metallic, inorganic, organic, charged, and neutral compounds. The material removes mercury from both organic wastes, such as pump oils, and from aqueous wastes. Mercury-loaded SAMMS not only passes TCLP tests, but also has good long-term durability as a waste form because: (1) the covalent binding between mercury and SAMMS has good resistance in ion-exchange, oxidation, and hydrolysis over a wide pH range and (2) the uniform and small pore size of the mesoporous silica prevents bacteria from solubilizing the bound mercury.

    Produced water is a major waste generated at the oil and natural gas wells in the state of Texas. This water could be a possible source of new fresh water to meet the growing demands of the state after treatment and purification. Treatment of brine generated in oil fields or produced water with an ultrafiltration membranes were the subject of this thesis. The characterization of ultrafiltration membranes for oil and suspended solids removal of produced water, coupled with the reverse osmosis (RO) desalination of brine were studied on lab size membrane testing equipment and a field size testing unit to test whether a viable membrane system could be used to treat produced water. Oil and suspended solids were evaluated using turbidity and oil in water measurements taken periodically. The research considered the effect of pressure and flow rate on membrane performance of produced water treatment of three commercially available membranes for oily water. The study also analyzed the flux through the membrane and any effect it had on membrane performance. The research showed that an ultrafiltration membrane provided turbidity removal of over 99% and oil removal of 78% for the produced water samples. The results indicated that the ultrafiltration membranes would be asset as one of the first steps in purifying the water. Further results on selected RO membranes showed that salt rejection of greater than 97% could be achieved with satisfactory flux and at reasonable operating cost.

    Oil sludge, if unused, is one of the major industrial wastes needed to be treated for the petroleum refinery plant or petrochemical industry. It contains a large amount of combustibles with high heating values. The treatment of waste oil sludge by burning has certain benefit; however, it cannot provide the useful resource efficiently. On the other hand, the conversion of oil sludge to lower molecule weight organic compounds by pyrolysis not only solves the disposal problem but also matches the appeal of resource utilization. The major sources of oil sludge include the oil storage tank sludge, the biological sludge, the dissolve air flotation (DAF) scum, the American Petroleum Institute (API) separator sludge and the chemical sludge. In this study, the oil sludge from the oil storage tank of a typical petroleum refinery plant located in the northern Taiwan is used as the raw material of pyrolysis. Its heating value of dry basis and low heating value of wet basis are about 10,681 k cal/kg and 5,870 k cal/kg, respectively. The removal of the moisture of oil sludge significantly increases its heating value. The pyrolysis of oil sludge is conducted by the use of nitrogen as the carrier gas in the temperature range of 380 {approximately} 1,073 K and at various constant heating rates of 5.2, 12.8 and 21.8 K/min. The pyrolytic reaction is significant in 450 {approximately} 800 K and complex. For the sake of simplicity and engineering use, a one-reaction kinetic model is proposed for the pyrolysis of oil sludge, and is found to satisfactorily fit the experimental data. The activation energy, reaction order and frequency factor of the corresponding pyrolysis reaction in nitrogen for oil sludge are 78.22 kJ/mol, 2.92 and 9.48 105 l/min, respectively. These results are very useful for the proper design of the pyrolysis system of the oil sludge under investigation.

    A method of removing at least one polar component from a fluid stream. The method comprises providing a fluid stream comprising at least one nonpolar component and at least one polar component. The fluid stream is contacted with a supercritical solvent to remove the at least one polar component. The at least one nonpolar component may be a fat or oil and the at least one polar component may be water, dirt, detergents, or mixtures thereof. The supercritical solvent may decrease solubility of the at least one polar component in the fluid stream. The supercritical solvent may function as a solvent or as a gas antisolvent. The supercritical solvent may dissolve the nonpolar components of the fluid stream, such as fats or oils, while the polar components may be substantially insoluble. Alternatively, the supercritical solvent may be used to increase the nonpolarity of the fluid stream.

    Bench scale studies were conducted to evaluate conventional physical-chemical and biological treatment processes for removal of pollutants from retort water produced by in situ shale oil recovery methods. Prior to undertaking these studies, very little information had been reported on treatment of retort water. A treatment process train patterned after that generally used throughout the petroleum refining industry was envisioned for application to retort water. The treatment train would consist of processes for removing suspended matter, ammonia, biodegradable organics, and nonbiodegradable or refractory organics. The treatment processes evaluated include anaerobic digestion and activated sludge for removal of biodegradable organics and other oxidizable substances; activated carbon adsorption for removal of nonbiodegradable organics; steam stripping for ammonia removal; and chemical coagulation, sedimentation and filtration for removal of suspended matter. Preliminary cost estimates are provided.

    The purpose of this report is to define the objectives of the Oil and Gas Supply Model (OGSM), to describe the model`s basic approach, and to provide detail on how the model works. This report is intended as a reference document for model analysts, users, and the public. It is prepared in accordance with the Energy Information Administration`s (EIA) legal obligation to provide adequate documentation in support of its statistical and forecast reports (Public Law 93-275, Section 57(b)(2)). Projected production estimates of U.S. crude oil and natural gas are based on supply functions generated endogenously within National Energy Modeling System (NEMS) by the OGSM. OGSM encompasses domestic crude oil and natural gas supply by both conventional and nonconventional recovery techniques. Nonconventional recovery includes enhanced oil recovery (EOR), and unconventional gas recovery (UGR) from tight gas formations, Devonian shale and coalbeds. Crude oil and natural gas projections are further disaggregated by geographic region. OGSM projects U.S. domestic oil and gas supply for six Lower 48 onshore regions, three offshore regions, and Alaska. The general methodology relies on forecasted drilling expenditures and average drilling costs to determine exploratory and developmental drilling levels for each region and fuel type. These projected drilling levels translate into reserve additions, as well as a modification of the production capacity for each region. OGSM also represents foreign trade in natural gas, imports and exports by entry region. Foreign gas trade may occur via either pipeline (Canada or Mexico), or via transport ships as liquefied natural gas (LNG). These import supply functions are critical elements of any market modeling effort.

    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.

Most of the earlier paint used was lead-based paint. More recently, various non-lead-based paints, such as two-part epoxy, are used. For D & D (decontamination and decommissioning), it is desirable to remove the paints or other coatings rather than having to tear down and dispose of the entire building.

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

    2000-10-31T23:59:59.000Z

    The U.S. Department of Energy (DOE) has been using vitrification processes to convert high-level radioactive waste forms into a stable glass for disposal in waste repositories. Vitrification facilities at the Savannah River Site (SRS) and at the West Valley Demonstration Project (WVDP) are converting liquid high-level waste (HLW) by combining it with a glass-forming media to form a borosilicate glass, which will ensure safe long-term storage. Large, slurry fed melters, which are used for this process, were anticipated to have a finite life (on the order of two to three years) at which time they would have to be replaced using remote methods because of the high radiation fields. In actuality the melters useable life spans have, to date, exceeded original life-span estimates. Initial plans called for the removal of failed melters by placing the melter assembly into a container and storing the assembly in a concrete vault on the vitrification plant site pending size-reduction, segregation, containerization, and shipment to appropriate storage facilities. Separate facilities for the processing of the failed melters currently do not exist. Options for handling these melters include (1) locating a facility to conduct the size-reduction, characterization, and containerization as originally planned; (2) long-term storing or disposing of the complete melter assembly; and (3) attempting to refurbish the melter and to reuse the melter assembly. The focus of this report is to look at methods and issues pertinent to size-reduction and/or melter refurbishment in particular, removing the glass as a part of a refurbishment or to reduce contamination levels (thus allowing for disposal of a greater proportion of the melter as low level waste).

  9. Past, Present, and Future Production of Bio-oil

    SciTech Connect (OSTI)

    Steele, Philip; Yu, Fei; Gajjela, Sanjeev

    2009-04-01T23:59:59.000Z

    Bio-oil is a liquid product produced by fast pyrol-ysis of biomass. The fast pyrolysis is performed by heating the biomass rapidly (2 sec) at temperatures ranging from 350 to 650 oC. The vapors produced by this rapid heating are then condensed to produce a dark brown water-based emulsion composed of frag-ments of the original hemicellulose, cellulose and lignin molecules contained in the biomass. Yields range from 60 to 75% based on the feedstock type and the pyrolysis reactor employed. The bio-oil pro-duced by this process has a number of negative prop-erties that are produced mainly by the high oxygen content (40 to 50%) contributed by that contained in water (25 to 30% of total mass) and oxygenated compounds. Each bio-oil contains hundreds of chemi-cal compounds. The chemical composition of bio-oil renders it a very recalcitrant chemical compound. To date, the difficulties in utilizing bio-oil have limited its commercial development to the production of liq-uid smoke as food flavoring. Practitioners have at-tempted to utilize raw bio-oil as a fuel; they have also applied many techniques to upgrade bio-oil to a fuel. Attempts to utilize raw bio-oil as a combustion engine fuel have resulted in engine or turbine dam-age; however, Stirling engines have been shown to successfully combust raw bio-oil without damage. Utilization of raw bio-oil as a boiler fuel has met with more success and an ASTM standard has recently been released describing bio-oil characteristics in relation to assigned fuel grades. However, commercialization has been slow to follow and no reports of distribution of these bio-oil boiler fuels have been reported. Co-feeding raw bio-oil with coal has been successfully performed but no current power generation facilities are following this practice. Upgrading of bio-oils to hydrocarbons via hydroprocessing is being performed by several organizations. Currently, limited catalyst life is the obstacle to commercialization of this tech-nology. Researchers have developed means to increase the anhydrosugars content of bio-oil above the usual 3% produced during normal pyrolysis by mild acid pretreatment of the biomass feedstock. Mississippi State University has developed a proprietary method to produce an aqueous fraction containing more than 50% of anhydrosugars content. These anhydrosugars can be catalyzed to hydrogen or hydrocarbons; alter-nately, the aqueous fraction can be hydrolyzed to pro-duce a high-glucose content. The hydrolyzed product can then be filtered to remove microbial inhibitor compounds followed by production of alcohols by fer-mentation. Production of bio-oil is now considered a major candidate as a technology promising production of drop-in transportation and boiler fuels.

    This Oil Bypass Filter Technology Evaluation quarterly report (October–December 2004) details the ongoing fleet evaluation of oil bypass filter technologies being conducted by the Idaho National Laboratory (INL; formerly Idaho National Engineering and Environmental Laboratory) for the U.S. Department of Energy’s FreedomCAR & Vehicle Technologies Program. Eight INL four-cycle diesel-engine buses used to transport INL employees on various routes and six INL Chevrolet Tahoes with gasoline engines are equipped with oil bypass filter systems from the puraDYN Corporation. This quarter, three additional buses were equipped with bypass filters from Refined Global Solutions. Oil bypass filters are reported to have an engine oil filtering capability of less than 1 micron. Both the puraDYN and Refined Global Solutions bypass filters have a heating chamber to remove liquid contaminate from the oil. During the quarter, the eleven diesel engine buses traveled 62,188 miles, and as of January 3, 2005 the buses had accumulated 643,036 total test miles. Two buses had their engine oil changed this quarter. In one bus, the oil was changed due to its degraded quality as determined by a low total base number (<3.0 mg KOH/g). The other bus had high oxidation and nitration numbers (>30.0 Abs/cm). Although a total of six buses have had their oil changed during the last 26 months, by using the oil bypass filters the buses in the evaluation avoided 48 oil changes, which equates to 1,680 quarts (420 gallons) of new oil not consumed and 1,680 quarts of waste oil not generated. Therefore, over 80% of the oil normally required for oil-changes was not used, and, consequently, the evaluation achieved over 80% reduction in the amount of waste oil normally generated. The six Tahoe test vehicles traveled 39,514 miles, and as of January 3, 2005 the Tahoes had accumulated 189,970 total test miles. The Tahoe filter test is in transition. To increase the rate of bypass filter oil flow on the Tahoes, puraDYN provided a larger orifice assembly, and these are being changed out as the Tahoes come in for regular service.

    The aeromagnetic mapping techniques used in a regional aeromagnetic survey of the state are documented and a qualitative regional interpretation of the magnetic basement is presented. Geothermal gradients measured and data from oil well records indicate that geothermal resources in Kansas are of a low-grade nature. However, considerable variation in the gradient is noted statewide within the upper 500 meters of the sedimentary section; this suggests the feasibility of using groundwater for space heating by means of heat pumps.

    The purpose of this report is to define the objectives of the Oil and Gas Supply Model (OGSM), to describe the model`s basic approach, and to provide detail on how the model works. This report is intended as a reference document for model analysts, users, and the public. Projected production estimates of US crude oil and natural gas are based on supply functions generated endogenously within National Energy Modeling System (NEMS) by the OGSM. OGSM encompasses domestic crude oil and natural gas supply by both conventional and nonconventional recovery techniques. Nonconventional recovery includes enhanced oil recovery (EOR), and unconventional gas recovery (UGR) from tight gas formations, Devonian shale and coalbeds. Crude oil and natural gas projects are further disaggregated by geographic region. OGSM projects US domestic oil and gas supply for six Lower 48 onshore regions, three offshore regions, and Alaska. The general methodology relies on forecasted drilling expenditures and average drilling costs to determine exploratory and developmental drilling levels for each region and fuel type. These projected drilling levels translate into reserve additions, as well as a modification of the production capacity for each region. OGSM also represents foreign trade in natural gas, imports and exports by entry region.

  1. Emulsified industrial oils recycling

    SciTech Connect (OSTI)

    Gabris, T.

    1982-04-01T23:59:59.000Z

    The industrial lubricant market has been analyzed with emphasis on current and/or developing recycling and re-refining technologies. This task has been performed for the United States and other industrialized countries, specifically France, West Germany, Italy and Japan. Attention has been focused at emulsion-type fluids regardless of the industrial application involved. It was found that emulsion-type fluids in the United States represent a much higher percentage of the total fluids used than in other industrialized countries. While recycling is an active matter explored by the industry, re-refining is rather a result of other issues than the mere fact that oil can be regenerated from a used industrial emulsion. To extend the longevity of an emulsion is a logical step to keep expenses down by using the emulsion as long as possible. There is, however, another important factor influencing this issue: regulations governing the disposal of such fluids. The ecological question, the respect for nature and the natural balances, is often seen now as everybody's task. Regulations forbid dumping used emulsions in the environment without prior treatment of the water phase and separation of the oil phase. This is a costly procedure, so recycling is attractive since it postpones the problem. It is questionable whether re-refining of these emulsions - as a business - could stand on its own if these emulsions did not have to be taken apart for disposal purposes. Once the emulsion is separated into a water and an oil phase, however, re-refining of the oil does become economical.

    At its heart, Arab oil policy is inseparable from Arab economic and social policy. This holds whether we are talking about the Arab nations as a group or each separately. The seven Arab nations covered in this report-Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates--participate in several organizations focusing on regional cooperation regarding economic development, social programs, and Islamic unity, as well as organizations concerned with oil policies. This report focuses on the oil-related activities of the countries that may reveal the de facto oil policies of the seven Persian Gulf nations. Nevertheless it should be kept in mind that the decision makers participating in the oil policy organizations are also involved with the collaborative efforts of these other organizations. Oil policies of five of the seven Arab nations are expressed within the forums of the Organization of Petroleum Exporting Countries (OPEC) and the Organization of Arab Petroleum Exporting Countries (OAPEC). Only Oman, among the seven, is not a member of either OAPEC or OPEC; Bahrain is a member of OAPEC but not of OPEC. OPEC and OAPEC provide forums for compromise and cooperation among their members. Nevertheless, each member state maintains its own sovereignty and follows its own policies. Each country deviates from the group prescription from time to time, depending upon individual circumstances.

    The eleventh Energy Modeling Forum (EMF) working group met four times over the 1989--1990 period to compare alternative perspectives on international oil supplies and demands through 2010 and to discuss how alternative supply and demand trends influence the world's dependence upon Middle Eastern oil. Proprietors of eleven economic models of the world oil market used their respective models to simulate a dozen scenarios using standardized assumptions. From its inception, the study was not designed to focus on the short-run impacts of disruptions on oil markets. Nor did the working group attempt to provide a forecast or just a single view of the likely future path for oil prices. The model results guided the group's thinking about many important longer-run market relationships and helped to identify differences of opinion about future oil supplies, demands, and dependence.

  17. Volume 9: A Review of Socioeconomic Impacts of Oil Shale Development WESTERN OIL SHALE DEVELOPMENT: A TECHNOLOGY ASSESSMENT

    SciTech Connect (OSTI)

    Rotariu,, G. J.

    1982-02-01T23:59:59.000Z

    The development of an oil shale industry in northwestern Colorado and northeastern Utah has been forecast at various times since early this century, but the comparatively easy accessibility of other oil sources has forestalled development. Decreasing fuel supplies, increasing energy costs, and the threat of a crippling oil embargo finally may launch a commercial oil shale industry in this region. Concern for the possible impacts on the human environment has been fostered by experiences of rapid population growth in other western towns that have hosted energy resource development. A large number of studies have attempted to evaluate social and economic impacts of energy development and to determine important factors that affect the severity of these impacts. These studies have suggested that successful management of rapid population growth depends on adequate front-end capital for public facilities, availability of housing, attention to human service needs, long-range land use and fiscal planning. This study examines variables that affect the socioeconomic impacts of oil shale development. The study region is composed of four Colorado counties: Mesa, Moffat, Garfield and Rio Blanco. Most of the estimated population of 111 000 resides in a handful of urban areas that are separated by large distances and rugged terrain. We have projected the six largest cities and towns and one planned company town (Battlement Mesa) to be the probable centers for potential population impacts caused by development of an oil shale industry. Local planners expect Battlement Mesa to lessen impacts on small existing communities and indeed may be necessary to prevent severe regional socioeconomic impacts. Section II describes the study region and focuses on the economic trends and present conditions in the area. The population impacts analyzed in this study are contingent on a scenario of oil shale development from 1980-90 provided by the Department of Energy and discussed in Sec. III. We recognize that the rate of development, the magnitude of development, and the technology mix that will actually take place remain uncertain. Although we emphasize that other energy and mineral resources besides oil shale may be developed, the conclusions reached in this study reflect only those impacts that would be felt from the oil shale scenario. Socioeconomic impacts in the region reflect the uneven growth rate implied by the scenario and will be affected by the timing of industry developments, the length and magnitude of the construction phase of development, and the shift in employment profiles predicted in the scenario. The facilities in the southern portion of the oil shale region, those along the Colorado River and Parachute Creek, show a peak in the construction work force in the mid-1980s, whereas those f acil it i es in the Piceance Creek Bas into the north show a construction peak in the late 1980s. Together, the facilities will require a large construction work force throughout the decade, with a total of 4800 construction workers required in 1985. Construction at the northern sites and second phase construction in the south will require 6000 workers in 1988. By 1990, the operation work force will increase to 7950. Two important characteristics of oil shale development emerge from the work force estimates: (1) peak-year construction work forces will be 90-120% the size of the permanent operating work force; and (2) the yearly changes in total work force requirements will be large, as much as 900 in one year at one facility. To estimate population impacts on individual communities, we devised a population distribution method that is described in Sec. IV. Variables associated with the projection of population impacts are discussed and methodologies of previous assessments are compared. Scenario-induced population impacts estimated by the Los Alamos method are compared to projections of a model employed by the Colorado West Area Council of Governments. Oil shale development in the early decade, as defined by the scenario, will produce growth primarily

    To evaluate its ability to remove phenol from aqueous solution, Jordanian {open_quotes}spent{close_quotes} oil shale, an abundant natural resource, has been used in an experimental adsorption study. Equilibrium of the system has been determined at three temperatures: 30, 40, and 55{degrees}C. The resulting experimental equilibrium isotherms are well represented by Frendlich, Langmuir, and Redlich-Peterson isotherms. The relevant parameters for these isotherms, as regressed from the experimental equilibrium data, are presented. Effects of solution pH (in the range of 3-11), in addition to effects of three inorganic salts (Kl, KCl, and NaCl), on the equilibrium isotherms were also investigated. The effects of pH in the presence of KI and NaCl were also investigated for a possible interaction between salts and solution pH. The initial concentration of phenol in the aqueous system studied ranges from 10 to 200 ppm. Experimental results show that while an acidic solution has no effect on the adsorption capacity of spent oil shale to phenol, a highly basic solution reduces its adsorbability. No sound effect was observed for the inorganic salts studied on the adsorption of phenol on spent oil shale. The experimental results show that there is no interaction between the pH of solution and the presence of salts. In spite of its ability to remove phenol, spent oil shale showed a very low equilibrium capacity (of an order of magnitude of 1 mg/g). Should the adsorption capacity of the shale be improved (by different treatment processes, such as grafting, surface conditioning), results of this study will find a direct practical implication in serving as {open_quotes}raw{close_quotes} reference data for comparison purposes.

  6. Environmental assessment of oil degasification at four Strategic Petroleum Reserve facilities in Texas and Louisiana

    1994-09-01T23:59:59.000Z

    The U.S. Department of Energy (DOE) proposes to treat gassy oil at four Strategic Petroleum Reserve (SPR) storage sites to lower the gas content of the stored crude oil and help ensure safe transfer of the oil during drawdown. The crude oil is stored underground in caverns created in salt domes. The degree of gassiness of the oil varies substantially among sites and among caverns within a site. This environmental assessment describes the proposed degasification operation, its alternatives, and potential environmental impacts. The need for degasification has arisen because over time, gases, principally methane and nitrogen, have migrated into and become dissolved in the stored crude oil. This influx of gas has raised the crude oil vapor pressure above limits required by safety and emission guidelines. When oil is drawn from the caverns, excess gases may come out of solution. Based on preliminary data from an ongoing sampling program, between 200 and 350 million of the 587 million barrels of crude oil stored at these four sites would require processing to remove excess gas. Degasification, a commonly used petroleum industry process, would be done at four crude oil storage facilities: Bryan Mound and Big Hill in Texas, and West Hackberry and Bayou Choctaw in Louisiana. DOE would use a turnkey services contract for engineering, procurement, fabrication, installation, operation and maintenance of two degasification plants. These would be installed initially at Bryan Mound and West Hackberry. Degasification would be complete in less than three years of continuous operations. This report summarizes the environmental impacts of this gasification process.

    Particulate oil shale is subjected to a pyrolysis with a hot, non-oxygenous gas in a pyrolysis vessel, with the products of the pyrolysis of the shale contained kerogen being withdrawn as an entrained mist of shale oil droplets in a gas for a separation of the liquid from the gas. Hot retorted shale withdrawn from the pyrolysis vessel is treated in a separate container with an oxygenous gas so as to provide combustion of residual carbon retained on the shale, producing a high temperature gas for the production of some steam and for heating the non-oxygenous gas used in the oil shale retorting process in the first vessel. The net energy recovery includes essentially complete recovery of the organic hydrocarbon material in the oil shale as a liquid shale oil, a high BTU gas, and high temperature steam.

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

    This article investigates the correlation structure of the global crude oil market using the daily returns of 71 oil price time series across the world from 1992 to 2012. We identify from the correlation matrix six clusters of time series exhibiting evident geographical traits, which supports Weiner's (1991) regionalization hypothesis of the global oil market. We find that intra-cluster pairs of time series are highly correlated while inter-cluster pairs have relatively low correlations. Principal component analysis shows that most eigenvalues of the correlation matrix locate outside the prediction of the random matrix theory and these deviating eigenvalues and their corresponding eigenvectors contain rich economic information. Specifically, the largest eigenvalue reflects a collective effect of the global market, other four largest eigenvalues possess a partitioning function to distinguish the six clusters, and the smallest eigenvalues highlight the pairs of time series with the largest correlation coefficie...

    As a result of the stabilization of oil prices in 1987 following their collapse in 1986, the rate of slowdown in Far East exploration activities began to ease. Seismic acquisition increased slightly, and the fall in exploratory drilling was less dramatic in 1987 than in 1986. No major discoveries were reported during 1987, although small-to-medium-size oil and gas discoveries added to the potential reserves of Bangladesh, India, Indonesia, Japan, People's Republic of China, Pakistan, Republic of China, and Thailand. Development drilling continued to rise by a modest amount. Far East oil and condensate production decreased in 1987 by just over 1% to 5.37 million b/d, whereas gas output rose to 11.7 bcf/day. New acreage awards were significantly higher in 1987 than in 1986, particularly in some of the region's key producing countries. 16 figs., 11 tabs.

    A significant fraction of U.S. natural gas reserves are subquality due to the presence of acid gases and nitrogen; 13% of existing reserves (19 trillion cubic feed) may be contaminated with hydrogen sulfide. For natural gas to be useful as fuel and feedstock, this hydrogen sulfide has to be removed to the pipeline specification of 4 ppm. The technology used to achieve these specifications has been amine, or similar chemical or physical solvent, absorption. Although mature and widely used in the gas industry, absorption processes are capital and energy-intensive and require constant supervision for proper operation. This makes these processes unsuitable for treating gas at low throughput, in remote locations, or with a high concentration of acid gases. The U.S. Department of Energy, recognizes that exploitation of smaller, more sub-quality resources will be necessary to meet demand as the large gas fields in the U.S. are depleted. In response to this need, Membrane Technology and Research, Inc. (MTR) has developed membranes and a membrane process for removing hydrogen sulfide from natural gas. During this project, high-performance polymeric thin-film composite membranes were brought from the research stage to field testing. The membranes have hydrogen sulfide/methane selectivities in the range 35 to 60, depending on the feed conditions, and have been scaled up to commercial-scale production. A large number of spiral-wound modules were manufactured, tested and optimized during this project, which culminated in a field test at a Shell facility in East Texas. The short field test showed that membrane module performance on an actual natural gas stream was close to that observed in the laboratory tests with cleaner streams. An extensive technical and economic analysis was performed to determine the best applications for the membrane process. Two areas were identified: the low-flow-rate, high-hydrogen-sulfide-content region and the high-flow-rate, high-hydrogen-sulfide-content region. In both regions the MTR membrane process will be combined with another process to provide the necessary hydrogen sulfide removal from the natural gas. In the first region the membrane process will be combined with the SulfaTreat fixed-bed absorption process, and in the second region the membrane process will be combined with a conventional absorption process. Economic analyses indicate that these hybrid processes provide 20-40% cost savings over stand-alone absorption technologies.

  4. RESEARCH OIL RECOVERY MECHANISMS IN HEAVY OIL RESERVOIRS

    1999-06-01T23:59:59.000Z

    The United States continues to rely heavily on petroleum fossil fuels as a primary energy source, while domestic reserves dwindle. However, so-called heavy oil (10 to 20{sup o}API) remains an underutilized 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 such as pressure depletion and water injection. Thermal recovery is especially important for this class of reservoirs because adding heat, usually via steam injection, generally reduces oil viscosity dramatically. This improves displacement efficiency. The research described here was directed toward improved understanding of thermal and heavy-oil production mechanisms and is categorized into: (1) flow and rock properties; (2) in-situ combustion; (3) additives to improve mobility control; (4) reservoir definition; and (5) support services. The scope of activities extended over a three-year period. Significant work was accomplished in the area of flow properties of steam, water, and oil in consolidated and unconsolidated porous media, transport in fractured porous media, foam generation and flow in homogeneous and heterogeneous porous media, the effects of displacement pattern geometry and mobility ratio on oil recovery, and analytical representation of water influx. Significant results are described.

    This feasibility study has indicated that of the approximately 120,000 tons of steel available to be recycled from used oil filters (UOF's), a maximum blast furnace charge of 2% of the burden may be anticipated for short term use of a few months. The oil contained in the most readily processed UOF's being properly hot drained and crushed is approximately 12% to 14% by weight. This oil will be pyrolized at a rate of 98% resulting in additional fuel gas of 68% and a condensable hydrocarbon fraction of 30%, with the remaining 2% resulting as carbon being added into the burden. Based upon the writer's collected information and assessment, there appears to be no operational problems relating to the recycling of UOF's to the blast furnace. One steel plant in the US has been routinely charging UOF's at about 100 tons to 200 tons per month for many years. Extensive analysis and calculations appear to indicate no toxic consideration as a result of the pyrolysis of the small contained oil ( in the 'prepared' UOFs) within the blast furnace. However, a hydrocarbon condensate in the ''gasoline'' fraction will condense in the blast furnace scrubber water and may require additional processing the water treatment system to remove benzene and toluene from the condensate. Used oil filters represent an additional source of high quality iron units that may be effectively added to the charge of a blast furnace for beneficial value to the operator and to the removal of this resource from landfills.

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

The system includes a differential pressure flow meter which samples pressure readings at various points of interest throughout the system and uses pressure differentials derived from the pressure readings to determine gas and liquid phase mass flow rates of the high void fraction multiphase flow. One or both of the gas and liquid phase mass flow rates are then compared with predetermined criteria. In the event such mass flow rates satisfy the predetermined criteria, a well control system implements a correlating adjustment action respecting the multiphase flow. In this way, various parameters regarding the high void fraction multiphase flow are used as control inputs to the well control system and thus facilitate management of well operations.

    When shale oils are applied at higher dose levels the standard observation of tumor production and latency are often obscured by a severe inflammatory response leading to epidermal degeneration. The two experiments reported here are still in progress, however the interim results are useful in assessing both the phlogistic and tumorigenic properties of three shale oils. Three shale oils were tested in these experiments. The first crude oil (OCSO No. 6) was produced in a modified in situ report at Occidental Oil Company's Logan Wash site near Debeque, Colorado. The second crude oil (PCSO II) was produced in the above ground Paraho vertical-kiln retort located at Anvil Points near Rifle, Colorado and the third oil was the hydrotreated daughter product of the Paraho crude (PCSO-UP). Experiment I was designed to determine the highest dose level at which tumor latency could be measured without interference from epidermal degeneration. Experiment II was designed to determine the effect of application frequency on both tumor response and inflammatory phenomena. Complete epidermal degeneration was used as the only measure of severe inflammation. Relative tumorigenicity was based on the number of tumor bearing mice without regard to multiple tumors on individual animals. In both experiments, tumor occurrence was confirmed one week after initial appearance. The sex-related difference in inflammatory response is striking and certanly has significance for experimental design. An increased phlogistic sensitivity expressed in male mice could affect the meaning of an experiment where only one sex was used.

    The project consists of 3 tasks: (1) Developing a Production Environmental Database (PED) with the purpose of investigating the current industry waste storage and disposal practices by different regions, states and types of waste and investigating the environmental impacts associated with these practices; (2) Evaluating the suitability of available and developing technologies for treating produced water and identifying applicable unit process configurations; and (3) Evaluating the costs associated with various degrees of treatment achievable by different configurations. Records of wells drilled during the years 1986 through 1991 were compiled from industry reports. Overall, drilling has decreased from an average of 60,000 wells/yr for the period 1981 through 1985 to 20,000/yr during 1986 through 1991. A produced water database was developed from data and information provided by the various state and federal agencies. Currently, the database has information on the production of oil, gas and brines from 24 states. The data from the produced water database indicate that for the most part, Class II Injection seemed to be the common disposal method. Other methods included evaporation, surface disposal via NPDES permit, road spreading, hauling out-of-state, and annular disposal. A survey of oil and gas operators has been developed, reviewed and edited. The survey is divided-by topic into three sections. (1) drilling wastes; (2) associated wastes; and (3) produced water. The objective of the survey is to develop more current information on the waste volumes and disposal methods used during 1986 through 1991. The possible treatment scenarios for produced water have been identified. Organic and inorganic contaminant removal, liquid/solid separation and liquid/emulsified oil separation have been identified as the main objectives of the treatment of produced water.

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

    The recovery of oil from oil shale is provided in a fluidized bed by using a fluidizing medium of a binary mixture of carbon dioxide and 5 steam. The mixture with a steam concentration in the range of about 20 to 75 volume percent steam provides an increase in oil yield over that achievable by using a fluidizing gas of carbon dioxide or steam alone when the mixture contains higher steam concentrations. The operating parameters for the fluidized bed retorted are essentially the same as those utilized with other gaseous fluidizing mediums with the significant gain being in the oil yield recovered which is attributable solely to the use of the binary mixture of carbon dioxide and steam. 2 figs.

    The present invention is directed to an improved method for enhanced recovery of oil from relatively "cold" reservoirs by carbon dioxide flooding. In oil reservoirs at a temperature less than the critical temperature of 87.7.degree. F. and at a pore pressure greater than the saturation pressure of carbon dioxide at the temperature of the reservoir, the carbon dioxide remains in the liquid state which does not satisfactorily mix with the oil. However, applicants have found that carbon dioxide can be vaporized in situ in the reservoir by selectively reducing the pore pressure in the reservoir to a value less than the particular saturated vapor pressure so as to greatly enhance the mixing of the carbon dioxide with the oil.

    Oxidation of NO to NO[sub 2] has been proposed as a method for enhancing NO[sub x] removals in conventional flue gas desulfurization (FGD) processes. This experimental investigation characterizes the removals of NO[sub 2] and SO[sub 2] in a 1.1 m[sup 3](standard)/min spray dryer/baghouse system. Flue gas was generated by burning a No. 2 fuel oil, which was subsequently spiked upstream of the spray dryer with NO[sub 2] or SO[sub 2] or both. Lime slurry was injected via a rotary atomizer into the spray dryer. Variables studied include the approach to the adiabatic saturation temperature, stoichiometric ratio, SO[sub 2] concentration, and NO[sub 2] concentration. Significant quantities of NO[sub 2] are scrubbed in this system, and over half of the total removal (at inlet NO[sub 2] > 400 ppm) occurs in the baghouse. Increasing NO[sub 2] concentrations enhance the amount of NO[sub x] removed in the system. Also, the presence of significant quantities of NO[sub 2] enhances the baghouse SO[sub 2] removal. Although up to 72% NO[sub 2] removals were obtained, concentrations of NO[sub 2] that exited the system were greater than 50 ppm for all conditions investigated.

    Six analyzed oils, produced from Middle jurassic to Upper Cretaceous strata in the Middle Ob region of the West Siberian basin, show biomarker and stable carbon isotope compositions indicating an origin from the Upper Jurassic Bazhenov Formation. The chemical compositions of these oils are representative of more than 85% of the reserves in West Siberia (Kontorovich et al., 1975). Bazhenov-sourced oil in Cenomanian strata in the Van-Egan field underwent biodegradation in the reservoir, resulting in a low API gravity, an altered homohopane distribution, and the appearance of 25-norhopanes without alteration of the steranes. High API gravity oil from the Salym field has surpassed the peak of the oil window, consistent with abnormally high temperatures and pressures in the Bazhenov source rock from which it is produced. The remaining oils are very similar, including samples from Valanginian and Bathonian-Callovian intervals in a sequence of stacked reservoirs in the Fedorov field. Bazhenov rock samples from the study area contain abundant oil-prone, marine organic matter preserved under anoxic conditions. While the Upper Jurassic Vasyugan Formation shows lower oil-regenerative potential than the Bazhenov Formation, it cannot be excluded as a source rock because insufficient sample was available for biomarker analysis. Core from the Lower to Middle Jurassic Tyumen Formation in the YemYegov 15 well was compared with the oils because it is thermally mature and shows TOC and HI values, indicating slightly more favorable oil-generative characteristics than the average for the formation (2.75 wt. % for 270 samples; 95 mg HC/g TOC for 25 samples). The core contains terrigenous, gas-prone organic matter that shows no relationship with the analyzed oils. 59 refs., 15 figs., 8 tabs.

    As part of the current Hanford mission of environmental cleanup, various long length equipment must be removed from highly radioactive waste tanks. The removal of equipment will utilize portions of the Equipment Removal System for Project W320 (ERS-W320), specifically the 50 ton hydraulic trailer system. Because the ERS-W320 system was designed to accommodate much heavier equipment it is adequate to support the dead weight of the trough, carriage and related equipment for 241AZ101 pump removal project. However, the ERS-W320 components when combined with the trough and its` related components must also be analyzed for overturning due to wind loads. Two troughs were designed, one for the 20 in. diameter carriage and one for the 36 in. diameter carriage. A proposed 52 in. trough was not designed and, therefore is not included in this document. In order to fit in the ERS-W320 strongback the troughs were design with the same widths. Structurally, the only difference between the two troughs is that more material was removed from the stiffener plates on the 36 in trough. The reduction in stiffener plate material reduces the allowable load. Therefore, only the 36 in. trough was analyzed.

    Joint funding by the Department of Energy and the State of Texas has Permitted a three year, multi-disciplinary investigation to enhance oil recovery from a dual porosity, fractured, low matrix permeability oil reservoir to be initiated. The Austin Chalk producing horizon trending thru the median of Texas has been identified as the candidate for analysis. Ultimate primary recovery of oil from the Austin Chalk is very low because of two major technological problems. The commercial oil producing rate is based on the wellbore encountering a significant number of natural fractures. The prediction of the location and frequency of natural fractures at any particular region in the subsurface is problematical at this time, unless extensive and expensive seismic work is conducted. A major portion of the oil remains in the low permeability matrix blocks after depletion because there are no methods currently available to the industry to mobilize this bypassed oil. The following multi-faceted study is aimed to develop new methods to increase oil and gas recovery from the Austin Chalk producing trend. These methods may involve new geological and geophysical interpretation methods, improved ways to study production decline curves or the application of a new enhanced oil recovery technique. The efforts for the second year may be summarized as one of coalescing the initial concepts developed during the initial phase to more in depth analyses. Accomplishments are predicting natural fractures; relating recovery to well-log signatures; development of the EOR imbibition process; mathematical modeling; and field test.

    Limited field trial results of a heating oil additive package developed to minimize unscheduled maintenance indicate that it achieves its goal of keeping heating oil systems cleaner. The multifunctional additive package was developed to provide improved fuel oxidation stability, improved corrosion protection, and dispersency. This combination of performance benefits was chosen because we believed it would retard the formation of sludge, as well as allow sludge already present to be carried through the system without fouling the fuel system components (dispersency should keep sludge particles small so they pass through the filtering system). Since many unscheduled maintenance calls are linked to fouling of the fuel filtering system, the overall goal of this technology is to reduce these maintenance calls. Photographic evidence shows that the additive package not only reduces the amount of sludge formed, but even removes existing sludge from filters and pump strainers. This {open_quotes}clean-up{close_quotes} performance is provided trouble free: we found no indication that nozzle/burner performance was impaired by dispersing sludge from filters and pump strainers. Qualitative assessments from specific accounts that used the premium heating oil also show marked reductions in unscheduled maintenance.

    Information on the potential health effects of a developing oil shale industry can be derived from two major sources: (1) the historical experience in foreign countries that have had major industries; and (2) the health effects research that has been conducted in the US in recent years. The information presented here is divided into two major sections: one dealing with the experience in foreign countries and the second dealing with the more recent work associated with current oil shale development in the US. As a result of the study, several observations can be made: (1) most of the current and historical data from foreign countries relate to occupational hazards rather than to impacts on regional populations; (2) neither the historical evidence from other countries nor the results of current research have shown pulmonary neoplasia to be a major concern, however, certain types of exposure, particularly such mixed source exposures as dust/diesel or dust/organic-vapor have not been adequately studied and the lung cancer question is not closed; (3) the industry should be alert to the incidence of skin disease in the industrial setting, however, automated techniques, modern industrial hygiene practices and realistic personal hygiene should greatly reduce the hazards associated with skin contact; and (4) the entire question of regional water contamination and any resultant health hazard has not been adequately addressed. The industrial practice of hydrotreating the crude shale oil will diminish the carcinogenic hazard of the product, however, the quantitative reduction of biological activity is dependent on the degree of hydrotreatment. Both Soviet and American experimentalists have demonstrated a correlation betweed carcinogenicity/toxicity and retorting temperature; the higher temperatures producing the more carcinogenic or toxic products.

    Systems for removing arsenic from water by addition of inexpensive and commonly available magnesium oxide, magnesium hydroxide, calcium oxide, or calcium hydroxide to the water. The hydroxide has a strong chemical affinity for arsenic and rapidly adsorbs arsenic, even in the presence of carbonate in the water.

    This study provides a spatially comprehensive assessment of sustainable agricultural residue removal potential across the United States. Earlier assessments determining the quantity of agricultural residue that could be sustainably removed for bioenergy production at the regional and national scale faced a number of computational limitations. These limitations included the number of environmental factors, the number of land management scenarios, and the spatial fidelity and spatial extent of the assessment. This study utilizes integrated multi-factor environmental process modeling and high fidelity land use datasets to perform a spatially comprehensive assessment of sustainably removable agricultural residues across the conterminous United States. Soil type represents the base spatial unit for this study and is modeled using a national soil survey database at the 10 – 100 m scale. Current crop rotation practices are identified by processing land cover data available from the USDA National Agricultural Statistics Service Cropland Data Layer database. Land management and residue removal scenarios are identified for each unique crop rotation and crop management zone. Estimates of county averages and state totals of sustainably available agricultural residues are provided. The results of the assessment show that in 2011 over 150 million metric tons of agricultural residues could have been sustainably removed across the United States. Projecting crop yields and land management practices to 2030, the assessment determines that over 207 million metric tons of agricultural residues will be able to be sustainably removed for bioenergy production at that time.

    Surfactant flooding has the potential to significantly increase recovery over that of conventional waterflooding. The availability of a large number of surfactant structures makes it possible to conduct a systematic study of the relation between surfactant structure and its efficacy for oil recovery. A combination of two surfactants was found to be particularly effective for application in carbonate formations at low temperature. A formulation has been designed for a particular field application. The addition of an alkali such as sodium carbonate makes possible in situ generation of surfactant and significant reduction of surfactant adsorption. In addition to reduction of interfacial tension to ultra-low values, surfactants and alkali can be designed to alter wettability to enhance oil recovery. The design of the process to maximize the region of ultra-low IFT is more challenging since the ratio of soap to synthetic surfactant is a parameter in the conditions for optimal salinity. Compositional simulation of the displacement process demonstrates the interdependence of the various components for oil recovery. An alkaline surfactant process is designed to enhance spontaneous imbibition in fractured, oil-wet, carbonate formations. It is able to recover oil from dolomite core samples from which there was no oil recovery when placed in formation brine. Mobility control is essential for surfactant EOR. Foam is evaluated to improve the sweep efficiency of surfactant injected into fractured reservoirs. UTCHEM is a reservoir simulator specially designed for surfactant EOR. It has been modified to represent the effects of a change in wettability. Simulated case studies demonstrate the effects of wettability.

    The purpose of this research program is to understand the potential impact of an oil shale industry on environmental levels of trace contaminants in the region. The program involves a comprehensive study of the sources, release mechanisms, transport, fate, and effects of toxic trace chemicals, principally the trace elements, in an oil shale industry. The overall objective of the program is to evaluate the environmental and health consequences of the release of toxic trace elements by shale and oil production and use. The baseline geochemical survey shows that stable trace elements maps can be constructed for numerous elements and that the trends observed are related to geologic and climatic factors. Shale retorted by above-ground processes tends to be very homogeneous (both in space and in time) in trace element content. Leachate studies show that significant amounts of B, F, and Mo are released from retorted shales and while B and Mo are rapidly flushed out, F is not. On the other hand, As, Se, and most other trace elements are not present in significant quantities. Significant amounts of F and B are also found in leachates of raw shales. Very large concentrations of reduced sulfur species are found in leachates of processed shale. Very high levels of B and Mo are taken up in some plants growing on processed shale with and without soil cover. There is a tendency for some trace elements to associate with specific organic fractions, indicating that organic chelation or complexation may play an important role. Many of the so-called standard methods for analyzing trace elements in oil shale-related materials are inadequate. A sampling manual is being written for the environmental scientist and practicing engineer. A new combination of methods is developed for separating the minerals in oil shale into different density fractions. Microbial investigations have tentatively identified the existence of thiobacilli in oil shale materials such as leachates. (DC)

    A review of the various promoters and sorbents examined for the removal of mercury from flue gas is presented. Commercial sorbent processes are described along with the chemistry of the various sorbent-mercury interactions. Novel sorbents for removing mercury from flue gas are suggested. Since activated carbons are expensive, alternate sorbents and/or improved activated carbons are needed. Because of their lower cost, sorbent development work can focus on base metal oxides and halides. Additionally, the long-term sequestration of the mercury on the sorbent needs to be addressed. Contacting methods between the flue gas and the sorbent also merit investigation.

    Lutz Kilian; Key Words

    Research on oil markets conducted during the last decade has challenged long-held beliefs about the causes and consequences of oil price shocks. As the empirical and theoretical models used by economists have evolved, so has our understanding of the determinants of oil price shocks and of the interaction between oil markets and the global economy. Some of the key insights are that the real price of oil is endogenous with respect to economic fundamentals, and that oil price shocks do not occur ceteris paribus. This makes it necessary to explicitly account for the demand and supply shocks underlying oil price shocks when studying their transmission to the domestic economy. Disentangling cause and effect in the relationship between oil prices and the economy requires structural models of the global economy including oil and other commodity markets.

    The objective of this project is to develop practical, cost effective methods for stabilizing biomass-derived fast pyrolysis oil for at least six months of storage under ambient conditions. The U.S. Department of Energy has targeted three strategies for stabilizing bio-oils: (1) reducing the oxygen content of the organic compounds comprising pyrolysis oil; (2) removal of carboxylic acid groups such that the total acid number (TAN) of the pyrolysis oil is dramatically reduced; and (3) reducing the charcoal content, which contains alkali metals known to catalyze reactions that increase the viscosity of bio-oil. Alkali and alkaline earth metals (AAEM), are known to catalyze decomposition reactions of biomass carbohydrates to produce light oxygenates that destabilize the resulting bio-oil. Methods envisioned to prevent the AAEM from reaction with the biomass carbohydrates include washing the AAEM out of the biomass with water or dilute acid or infusing an acid catalyst to passivate the AAEM. Infusion of acids into the feedstock to convert all of the AAEM to salts which are stable at pyrolysis temperatures proved to be a much more economically feasible process. Our results from pyrolyzing acid infused biomass showed increases in the yield of anhydrosugars by greater than 300% while greatly reducing the yield of light oxygenates that are known to destabilize bio-oil. Particulate matter can interfere with combustion or catalytic processing of either syngas or bio-oil. It also is thought to catalyze the polymerization of bio-oil, which increases the viscosity of bio-oil over time. High temperature bag houses, ceramic candle filters, and moving bed granular filters have been variously suggested for syngas cleaning at elevated temperatures. High temperature filtration of bio-oil vapors has also been suggested by the National Renewable Energy Laboratory although there remain technical challenges to this approach. The fast pyrolysis of biomass yields three main organic products: condensable vapors, non-condensable gases, and liquid aerosols. Traditionally these are recovered by a spray quencher or a conventional shell and tube condenser. The spray quencher or condenser is typically followed by an electrostatic precipitator to yield 1 or 2 distinct fractions of bio-oil. The pyrolyzer system developed at Iowa State University incorporates a proprietary fractionating condenser train. The system collects the bio-oil into five unique fractions. For conditions typical of fluidized bed pyrolyzers, stage fractions have been collected that are carbohydrate-rich (anhydrosugars), lignin-rich, and an aqueous solution of carboxylic acids and aldehydes. One important feature is that most of the water normally found in bio-oil appears in the last stage fraction along with several water-soluble components that are thought to be responsible for bio-oil aging (low molecular weight carboxylic acids and aldehydes). Research work on laser diagnostics for hot-vapor filtration and bio-oil recovery centered on development of analytical techniques for in situ measurements during fast pyrolysis, hot-vapor filtration, and fractionation relative to bio-oil stabilization. The methods developed in this work include laser-induced breakdown spectroscopy (LIBS), laser-induced incandescence (LII), and laser scattering for elemental analysis (N, O, H, C), detection of particulates, and detection of aerosols, respectively. These techniques were utilized in simulated pyrolysis environments and applied to a small-scale pyrolysis unit. Stability of Bio-oils is adversely affected by the presence of particulates that are formed as a consequence of thermal pyrolysis, improving the CFD simulations of moving bed granular filter (MBGF) is useful for improving the design of MBGF for bio-oil production. The current work uses fully resolved direct numerical simulation (where the flow past each granule is accurately represented) to calculate the filter efficiency that is used in the CFD model at all flow speeds. This study shows that fully-resolved direct numerical simulation (DNS

    An interdisciplinary research team of engineers, geologists, and computer scientists was assembled at LSU to develop unproved methods for prospecting for bypassed oil and to support oil and gas producers in Louisiana. The overall objective of the project was to develop methods for extending the producing life of several types of reservoirs by reducing the amount of oil being bypassed and abandoned. As part of this work, the team collected information available from public sources for several example reservoirs. One task of the project was to develop a format for the compilation of the extensive but cumbersome Louisiana reservoir data so that it could be used by government and industry to evaluate the resource and plan future activities. The existing information system maintained by Louisiana is a Production Audit Reporting System (PARS). It was designed to allow auditing of oil and gas production and severance taxes associated with this production. It was not intended to be used as a database for determining reservoir recovery efficiency or prospecting for oil and gas. Its use for these purposes, however, has been increasing. The database format suggested in this report would allow production information to be easily displayed by reservoir as well as by lease, unit, or well. The data collected as part of the bypassed-oil study was used to illustrate the proposed new format. This pilot database, or atlas, contains information available for 15 reservoirs. It is recommended that LSU continue to compile and publish database information on the potential for bypassed oil in Louisiana's active reservoirs. This technology-transfer activity should focus each year on those active reservoirs involved in hearings of the Louisiana Office of Conservation. It should also focus on reservoirs being screened by LSU for EOR.

    Electrofuels Project: MIT is using carbon dioxide (CO2) and hydrogen generated from electricity to produce natural oils that can be upgraded to hydrocarbon fuels. MIT has designed a 2-stage biofuel production system. In the first stage, hydrogen and CO2 are fed to a microorganism capable of converting these feedstocks to a 2-carbon compound called acetate. In the second stage, acetate is delivered to a different microorganism that can use the acetate to grow and produce oil. The oil can be removed from the reactor tank and chemically converted to various hydrocarbons. The electricity for the process could be supplied from novel means currently in development, or more proven methods such as the combustion of municipal waste, which would also generate the required CO2 and enhance the overall efficiency of MIT’s biofuel-production system.

    Easily removable, environmentally safe, low-density, syntactic foams are disclosed which are prepared by mixing insoluble microballoons with a solution of water and/or alcohol-soluble polymer to produce a pourable slurry, optionally vacuum filtering the slurry in varying degrees to remove unwanted solvent and solute polymer, and drying to remove residual solvent. The properties of the foams can be controlled by the concentration and physical properties of the polymer, and by the size and properties of the microballoons. The suggested solute polymers are non-toxic and soluble in environmentally safe solvents such as water or low-molecular weight alcohols. The syntactic foams produced by this process are particularly useful in those applications where ease of removability is beneficial, and could find use in packaging recoverable electronic components, in drilling and mining applications, in building trades, in art works, in the entertainment industry for special effects, in manufacturing as temporary fixtures, in agriculture as temporary supports and containers and for delivery of fertilizer, in medicine as casts and splints, as temporary thermal barriers, as temporary protective covers for fragile objects, as filters for particulate matter, which matter may be easily recovered upon exposure to a solvent, as in-situ valves (for one-time use) which go from maximum to minimum impedance when solvent flows through, and for the automatic opening or closing of spring-loaded, mechanical switches upon exposure to a solvent, among other applications.

    Easily removable, environmentally safe, low-density, syntactic foams are disclosed which are prepared by mixing insoluble microballoons with a solution of water and/or alcohol-soluble polymer to produce a pourable slurry, optionally vacuum filtering the slurry in varying degrees to remove unwanted solvent and solute polymer, and drying to remove residual solvent. The properties of the foams can be controlled by the concentration and physical properties of the polymer, and by the size and properties of the microballoons. The suggested solute polymers are non-toxic and soluble in environmentally safe solvents such as water or low-molecular weight alcohols. The syntactic foams produced by this process are particularly useful in those applications where ease of removability is beneficial, and could find use in packaging recoverable electronic components, in drilling and mining applications, in building trades, in art works, in the entertainment industry for special effects, in manufacturing as temporary fixtures, in agriculture as temporary supports and containers and for delivery of fertilizer, in medicine as casts and splints, as temporary thermal barriers, as temporary protective covers for fragile objects, as filters for particulate matter, which matter may be easily recovered upon exposure to a solvent, as in-situ valves (for one-time use) which go from maximum to minimum impedance when solvent flows through, and for the automatic opening or closing of spring-loaded, mechanical switches upon exposure to a solvent, among other applications. 1 fig.

    The Pentek coating removal technology was tested and is being evaluated at Florida International University (FIU) as a baseline technology. In conjunction with FIU`s evaluation of efficiency and cost, this report covers evaluation conducted for safety and health issues. It is a commercially available technology and has been used for various projects at locations throughout the country. The Pentek coating removal system consisted of the ROTO-PEEN Scaler, CORNER-CUTTER{reg_sign}, and VAC-PAC{reg_sign}. They are designed to remove coatings from steel, concrete, brick, and wood. The Scaler uses 3M Roto Peen tungsten carbide cutters while the CORNER-CUTTER{reg_sign} uses solid needles for descaling activities. These hand tools are used with the VAC-PAC{reg_sign} vacuum system to capture dust and debris as removal of the coating takes place. The safety and health evaluation during the testing demonstration focused on two main areas of exposure: dust and noise. Dust exposure minimal, but noise exposure was significant. Further testing for each exposure is recommended because of the environment where the testing demonstration took place. It is feasible that the dust and noise levels will be higher in an enclosed operating environment of different construction. In addition, other areas of concern found were arm-hand vibration, whole-body, ergonomics, heat stress, tripping hazards, electrical hazards, machine guarding, and lockout/tagout.

    Bilayers formed of two species of amphiphile of different chain lengths may segregate into thinner and thicker domains composed predominantly of the respective species. Using a coarse-grained mean-field model, we investigate how mixing oil with the amphiphiles affects the structure and thickness of the bilayer at and on either side of the boundary between two neighbouring domains. In particular, we find that oil molecules whose chain length is close to that of the shorter amphiphiles segregate to the thicker domain. This smooths the surface of the hydrophobic bilayer core on this side of the boundary, reducing its area and curvature and their associated free-energy penalties. The smoothing effect is weaker for oil molecules that are shorter or longer than this optimum value: short molecules spread evenly through the bilayer, while long molecules swell the thicker domain, increasing the surface area and curvature of the bilayer core in the interfacial region. Our results show that adding an appropriate oil could make the formation of domain boundaries more or less favourable, raising the possibility of controlling the domain size distribution.

    This study analyzed the recovery of oil from oil shale by use of proposed systems which incorporate beneficiation of the shale ore (that is concentration of the kerogen before the oil-recovery step). The objective was to identify systems which could be more attractive than conventional surface retorting of ore. No experimental work was carried out. The systems analyzed consisted of beneficiation methods which could increase kerogen concentrations by at least four-fold. Potentially attractive low-enrichment methods such as density separation were not examined. The technical alternatives considered were bounded by the secondary crusher as input and raw shale oil as output. A sequence of ball milling, froth flotation, and retorting concentrate is not attractive for Western shales compared to conventional ore retorting; transporting the concentrate to another location for retorting reduces air emissions in the ore region but cost reduction is questionable. The high capital and energy cost s results largely from the ball milling step which is very inefficient. Major improvements in comminution seem achievable through research and such improvements, plus confirmation of other assumptions, could make high-enrichment beneficiation competitive with conventional processing. 27 figures, 23 tables.

    As African countries continue a slow drift towards democratic government and market economics, the continent is increasingly attractive to international oil and gas companies. Though Africa remains politically diverse, and its volatile politics remains a major barrier to petroleum companies, a number of recent developments reflect its growing significance for the industry. Among recent projects and events reflecting changes in Africa: oil and gas exporter Algeria has invited foreign oil companies to help develop major gas discoveries, with a view to boosting exports to Europe; oil and gas producer Egypt invited foreign companies to explore in the Nile Delta region, and the result appears to be a flowering world scale gas play; west African offshore exploration has entered deep water and new areas, and a number of major projects are expected in years to come; Nigeria`s reputation as a difficult place to operate has been justified by recent political and civil events, but a long-planned liquefied natural gas (LNG) export plant is being built there; South Africa, which has returned to the international scene after years of trade isolation because of apartheid, is emerging as a potential driver for energy industry schemes throughout the continent. Activities are discussed.

    Eight horizontal wells have been drilled and completed in a steeply dipping Stevens sand reservoir in the Elk Hills field, Kern County, California. The subject reservoir, called the Stevens 26R, is a turbidite channel sand deposit one mile wide, three miles long, and one mile deep. Formation beds have a gross thickness up to 1,500 feet and dips as high as 60 degrees on the flanks. The original oil column of 1,810 feet has been pulled down to 200 feet by continual production since 1976. The reservoir management operating strategy has been full pressure maintenance by crestal gas injection since 1976. The steep dip of the formation makes gravity drainage the dominant drive mechanism. Additionally, improved recovery is coming from cycling dry gas through the large secondary gas cap region. The prudent placement of the horizontal wells above the oil/water contact promises to improve oil recovery and extend the operating life of the reservoir. Field results are given to compare the performance of the horizontal wells with the conventional wells. The horizontal wells produce at higher rates, lower draw downs, and lower gas/oil ratio which will extend the life of the project and result in higher recovery.

    Five Smackover (Upper Jurassic, Oxfordian) oil plays can be delineated in the eastern Gulf Coastal Plain. These include the basement ridge play, the regional peripheral fault trend play, the Mississippi interior salt basin play, the Mobile graben fault system play, and the Wiggins arch complex play. Plays are recognized by basinal position, relationships to regional structural features, and characteristic petroleum traps. Within two plays, subplays can be distinguished based on oil gravities and reservoir characteristics. Reservoirs are distinguished primarily by depositional setting and diagenetic overprint. The geology and petroleum characteristics of these plays are discussed.

Heteroatoms, N, S & O, are undesirable as components of a refinery feedstock, but are the basis for product value in agrochemicals, pharmaceuticals, surfactants, solvents, polymers, and a host of industrial materials. An economically viable, technologically feasible process scheme was developed in this research that promises to enhance the economics of oil shale development, both in the US and elsewhere in the world, in particular Estonia. Products will compete in existing markets for products now manufactured by costly synthesis routes. A premium petroleum refinery feedstock is also produced. The technology is now ready for pilot plant engineering studies and is likely to play an important role in developing a US oil shale industry.

    A process is proposed to convert oil shale by radio frequency heating over a period of months to years to create a product similar to natural petroleum. Electrodes would be placed in drill holes, either vertical or horizontal, and a radio frequency chosen so that the penetration depth of the radio waves is of the order of tens to hundreds of meters. A combination of excess volume production and overburden compaction drives the oil and gas from the shale into the drill holes, where it is pumped to the surface. Electrical energy for the process could be provided initially by excess regional capacity, especially off-peak power, which would generate {approx}3 x 10{sup 5} bbl/day of synthetic crude oil, depending on shale grade. The electricity cost, using conservative efficiency assumptions, is $4.70 to $6.30/bbl, depending on grade and heating rate. At steady state, co-produced gas can generate more than half the electric power needed for the process, with the fraction depending on oil shale grade. This would increase production to 7.3 x 10{sup 5} bbl/day for 104 l/Mg shale and 1.6 x 10{sup 6} bbl/day for 146 l/Mg shale using a combination of off-peak power and power from co-produced gas.

The microbial combination is capable of displacing residual oil from reservoir rock, which oil may be recovered by waterflooding without causing plugging of the reservoir rock. Further, the microorganisms are capable of being transported through the pores of the reservoir rock between said injection well and associated production wells, during waterflooding, which results in a larger area of the reservoir being covered by the oil-mobilizing microorganisms.
