Microbial gene functions enriched in the Deepwater Horizon deep-sea oil plume  

Science Conference Proceedings (OSTI)

The Deepwater Horizon oil spill in the Gulf of Mexico is the deepest and largest offshore spill in U.S. history and its impacts on marine ecosystems are largely unknown. Here, we showed that the microbial community functional composition and structure were dramatically altered in a deep-sea oil plume resulting from the spill. A variety of metabolic genes involved in both aerobic and anaerobic hydrocarbon degradation were highly enriched in the plume compared to outside the plume, indicating a great potential for intrinsic bioremediation or natural attenuation in the deep-sea. Various other microbial functional genes relevant to carbon, nitrogen, phosphorus, sulfur and iron cycling, metal resistance, and bacteriophage replication were also enriched in the plume. Together, these results suggest that the indigenous marine microbial communities could play a significant role in biodegradation of oil spills in deep-sea environments.

Why Sequence Thermoacidophiles of deep-sea hydrothermal vents?  

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

Thermoacidophiles of Thermoacidophiles of deep-sea hydrothermal vents? Bacteria that live in hydrothermal vents on land and deep underwater need to be able to tolerate high temperatures and harsh, nutrient-poor environments with high concentrations of metals. As a result of living in such environments, however, these bacteria have enzymes that are stable at high temperatures, which could be useful for producing alternative fuels. Thermoacidophiles Photo: University of Delaware Aquificales bacteria are often found in thermal streams and associated with sulfide precipitation. Sequencing some of these bacterial genomes -- specifically, Thermocrinis ruber, S. rodmanii and S. kristjansonnii -- could provide researchers with so-called "anchor genomes" that would be applied in turn to studies already being done on microbial communities in

New insights into microbial responses to oil spills from the Deepwater Horizon incident  

Science Conference Proceedings (OSTI)

On April 20, 2010, a catastrophic eruption of methane caused the Deepwater Horizon exploratory drill rig drilling the Macondo Well in Mississippi Canyon Block 252 (MC252) to explode. The Deepwater Horizon oil spill was unprecendeted for several reasons: the volume of oil released; the spill duration; the well depth; the distance from the shore-line (77 km or about 50 miles); the type of oil (light crude); and the injection of dispersant directly at the wellhead. This study clearly demonstrated that there was a profound and significant response by certain members of the in situ microbial community in the deep-sea in the Gulf of Mexico. In particular putative hydrocarbon degrading Bacteria appeared to bloom in response to the Deepwater Horizon oil spill, even though the temperature at these depths is never >5 C. As the plume aged the shifts in the microbial community on a temporal scale suggested that different, yet metabolically important members of the community were able to respond to a myriad of plume constituents, e.g. shifting from propane/ethane to alkanes and finally to methane. Thus, the biodegradation of hydrocarbons in the plume by Bacteria was a highly significant process in the natural attenuation of many compounds released during the Deepwater Horizon oil spill.

Standing Stocks and Faunal Zonation of Deep-Sea Benthos: Patterns and Predictions across Scales  

E-Print Network (OSTI)

The deep ocean (> 200-m depth) covers more than 65 percent of earth's surface and is known as the largest active carbon sink of the planet. Photosynthesis fixes inorganic carbon into organic rich-compounds to fuel the biological production in the upper ocean. A small portion of the photosynthetic carbon eventually sinks to the seafloor to support diverse deep-sea life. In this dissertation, the phytoplankton production and export flux of particulate organic carbon (POC) to the seafloor were linked to standing stocks and compositional changes of the deep-sea soft bottom assemblages. The pattern and processes of energy transfer from the surface ocean to the deep sea was examined by modeling the global benthic bacteria, meiofauna, macrofauna, and megafauna biomass from remotely sensed ocean color images and the seafloor relief. The analysis was then scaled down to the macrofauna of the Gulf of Mexico (GoM) to examine the global pattern on regional oceanic features with contrasting productivity regimes. These results suggested a universal decline of benthic standing stocks down the continental margins that is caused by an exponential decrease of export POC flux with depth. A revisit of historical epibenthic invertebrate sampling in the North Atlantic showed that both individual species and multi-species assemblages occurred in narrow depth bands that hugged the topography from the upper continental slope out to the Hatteras Abyssal Plain. The continuum compositional change suggested that the continuous decline of benthic food supply with depth was the potential driving force for the pattern of bathymetric faunal zonation. A broad, systematic survey across multiple depth transects in the northern GoM suggested that macrofauna zonation is not only taking place across isobaths, but also form the northeast to the northwest GoM due to a horizontal productivity gradient created by the nutrient-laden Mississippi River. Analyses of long-term demersal fish data from 1964 to 2002 in the northern GoM showed no evidence of large-scale faunal change across different sampling times. Base on the pooled data, a shift in rate of fish species replacement may be caused by complex biological interactions or changes in environmental heterogeneity along depth or productivity gradients.

Neutrino Detection, Position Calibration and Marine Science with Acoustic Arrays in the Deep Sea  

E-Print Network (OSTI)

Arrays of acoustic receivers are an integral part of present and potential future Cherenkov neutrino telescopes in the deep sea. They measure the positions of individual detector elements which vary with time as an effect of undersea currents. At the same time, the acoustic receivers can be employed for marine science purposes, in particular for monitoring the ambient noise environment and the signals emitted by the fauna of the sea. And last but not least, they can be used for studies towards acoustic detection of ultra-high-energy neutrinos. Measuring acoustic pressure pulses in huge underwater acoustic arrays with an instrumented volume of the order of 100 km^3 is a promising approach for the detection of cosmic neutrinos with energies exceeding 1 EeV. Pressure signals are produced by the particle cascades that evolve when neutrinos interact with nuclei in water, and can be detected over large distances in the kilometre range. In this article, the status of acoustic detection will be reviewed and plans for...

This book discusses the geological characterization of reservoir and production attributes of the Shackelford and Preston waterflood units, southeastern Midland County, West Texas. These two units, which are operated by Mobil Producing Texas and New Mexico, are part of the Permian Spraberry Trend. Conventional reserves in the Spraberry are estimated to be almost 60 million barrels of oil, and more than 4 billion barrels of unproduced mobile oil remain, making the Spraberry a prime target for extended conventional recovery from untapped or poorly drained reservoir compartments. The authors determine the stratigraphy of the formation, map sand distribution trends, and determine from cores and logs the extent and composition of facies that compose the principal reservoir units.

The Influence of deep-sea bed CO2 sequestration on small metazoan (meiofaunal) community structure and function  

SciTech Connect

We conducted a series of experiments in Monterey Submarine Canyon to examine potential ecological impacts of deep-ocean CO2 sequestration. Our focus was on responses of meiofaunal invertebrates (< 1 mm body length) living within the sediment at depths ranging between 3000-3600 m. Our particular emphasis was on harpacticoid copepods and nematodes. In the first phase of our DOE funding, we reported findings that suggest substantial (~80%) mortality to harpacticoid copepods. In the second phase of our funding we published additional findings from phase one and conducted follow-up experiments in the Monterey Canyon and in the laboratory. In one experiment we looked for evidence that meiofauna seek to escape areas where CO2 concentrations are elevated. â??Emergence trapsâ? near the source of the CO2-rich seawater caught significantly more harpacticoids than those far from it. The harpacticoids apparently attempted to escape from the advancing front of carbon dioxide-rich seawater and therefore presumably found exposure to it to be stressful. Although most were adversely affected, species differed significantly in the degree of their susceptibility. Unexpectedly, six species showed no effect and may be resistant. The hypothesis that harpacticoids could escape the effects of carbon dioxide-rich seawater by moving deeper into the seabed was not supported. Exposure to carbon dioxide-rich seawater created partially defaunated areas, but we found no evidence that disturbance-exploiting harpacticoid species invaded during the recovery of the affected area. Based on a detailed analysis of nematode biovolumes, we postulated that the nematode community in Monterey Canyon throughout the upper 3 cm suffered a high rate of mortality after exposure to CO2, and that nematodes were larger because postmortem expansions in body length and width occurred. Decomposition rates were probably low and corpses did not disintegrate in 30 days. The observable effects of a reduction in pH to about 7.0 after 30 days were as great as an extreme pH reduction (5.4), suggesting that â??moderateâ?? CO2 exposure, compared to the range of exposures possible following CO2 release, causes high mortality rates in the two most abundant sediment-dwelling metazoans (nematodes and copepods). While we found evidence for negative impacts on deep-sea benthos, we also observed that small-scale experiments with CO2 releases were difficult to replicate in the deep sea. Specifically, in one CO2-release experiment in the Monterey Canyon we did not detect an adverse impacts on benthic meiofauan. In laboratory experiments, we manipulated seawater acidity by addition of HCl and by increasing CO2 concentration and observed that two coastal harpacticoid copepod species were both more sensitive to increased acidity when generated by CO2. Copepods living in environments more prone to hypercapnia, such as mudflats, may be less sensitive to future acidification. Ocean acidification is also expected to alter the toxicity of waterborne metals by influencing their speciation in seawater. CO2 enrichment did not affect the free-ion concentration of Cd but did increase the free-ion concentration of Cu. Antagonistic toxicities were observed between CO2 with Cd, Cu and Cu free-ion. This interaction could be due to a competition for H+ and metals for binding sites.

A View of Antarctic Ice-Sheet Evolution from Sea-Level and Deep-Sea Isotope Changes During the Late Cretaceous-Cenozoic  

E-Print Network (OSTI)

The imperfect direct record of Antarctic glaciation has led to the delayed recognition of the initiation of a continent-sized ice sheet. Early studies interpreted initiation in the middle Miocene (ca 15 Ma). Most current studies place the first ice sheet in the earliest Oligocene (33.55 Ma), but there is physical evidence for glaciation in the Eocene. Though there are inherent limitations in sea-level and deep-sea isotope records, both place constraints on the size and extent of Late Cretaceous to Cenozoic Antarctic ice sheets. Sea-level records argue that small- to medium-size (typically 10-12 106 km3) ephemeral ice sheets occurred during the greenhouse world of the Late Cretaceous to middle Eocene. Deep-sea ?18O records show increases associated with many of these greenhouse sea-level falls, consistent with their attribution to ice-sheet growth. Global cooling began in the middle Eocene and culminated with the major earliest Oligocene (33.55 Ma) growth of a large (25 106 km3) Antarctic ice sheet that caused a 55-70 m eustatic fall and a 1 ?18O increase. This large ice sheet became a driver of climate change, not just a response to it, causing increased latitudinal thermal gradients and a spinning up of the oceans that, in turn, caused a dramatic reorganization of ocean circulation and chemistry.

Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes

Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes Print Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes Print Despite the considerable amount of iron that enters the oceans from the continents and from hydrothermal vents at mid-ocean ridges on the seafloor, there are large regions of the global ocean where iron availability is so low that it limits life. Oceanographers have long explained this anomaly by assuming that the iron in the sea is primarily incorporated as Fe(III) into inorganic minerals that lack both the mobility to circulate over long distance and bioavailability to sea life as an essential nutrient. Now, a collaboration led by researchers from the Woods Hole Oceanographic Institution has reported that the hydrothermal plumes emerging from the vents actually contain iron in both Fe(II) and Fe(III) oxidation states associated with organic material from nearby flora and fauna. The collaboration suggests that the organic matrices prevent oxidation and precipitation of the Fe(II), perhaps increasing both its circulation through the world's oceans and its bioavailability as a deep-sea nutrient.

Complete genome sequence of the aerobic, heterotroph Marinithermus hydrothermalis type strain (T1T) from a deep-sea hydrothermal vent chimney  

Science Conference Proceedings (OSTI)

Marinithermus hydrothermalis Sako et al. 2003 is the type species of the monotypic genus Marinithermus. M. hydrothermalis T1 T was the first isolate within the phylum ThermusDeinococcus to exhibit optimal growth under a salinity equivalent to that of sea water and to have an absolute requirement for NaCl for growth. M. hydrothermalis T1 T is of interest because it may provide a new insight into the ecological significance of the aerobic, thermophilic decomposers in the circulation of organic compounds in deep-sea hydrothermal vent ecosystems. This is the first completed genome sequence of a member of the genus Marinithermus and the seventh sequence from the family Thermaceae. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 2,269,167 bp long genome with its 2,251 protein-coding and 59 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Preservation of iron(II) by carbon-rich matrices in a hydrothermal plume  

SciTech Connect

Hydrothermal venting associated with mid-ocean ridge volcanism is globally widespread. This venting is responsible for a dissolved iron flux to the ocean that is approximately equal to that associated with continental riverine runoff. For hydrothermal fluxes, it has long been assumed that most of the iron entering the oceans is precipitated in inorganic forms. However, the possibility of globally significant fluxes of iron escaping these mass precipitation events and entering open-ocean cycles is now being debated, and two recent studies suggest that dissolved organic ligands might influence the fate of hydrothermally vented metals. Here we present spectromicroscopic measurements of iron and carbon in hydrothermal plume particles at the East Pacific Rise mid-ocean ridge. We show that organic carbon-rich matrices, containing evenly dispersed iron(II)-rich materials, are pervasive in hydrothermal plume particles. The absence of discrete iron(II) particles suggests that the carbon and iron associate through sorption or complexation. We suggest that these carbon matrices stabilize iron(II) released from hydrothermal vents in the region, preventing its oxidation and/or precipitation as insoluble minerals. Our findings have implications for deep-sea biogeochemical cycling of iron, a widely recognized limiting nutrient in the oceans.

Laboratory-Scale Simulation of Spiral Plumes in Fluid with Hight Ptandtl Number  

E-Print Network (OSTI)

We experimentally investigated the appearance of a plumes from local hot spot and study its interaction with cellular flow in closed cavity filled by silicon oil with Prandtl number Pr ~2*10^3 . Convective plume is generated by a local heat source, located on the top of the small rubber cylinder, which is located in the center of the bottom of the rectangular cell. Green laser has been used to simulate the hot-spot. Roll-type large-scale convective flow is generated by heating of the one vertical sides of cavity. Influence of power of hot point on the shape of plume has been investigated. It is shown that the presence of cellular convective motion may lead to the formation of a strange spiral convective plume. This plume looks like Archimedes spiral replaced on vertical plane. Physical mechanism of the formation of strange spiral plume and application of obtained results for mantle convection problems are discussed.

Plasma plume MHD power generator and method  

DOE Patents (OSTI)

Highly-conducting plasma plumes are ejected across the interplanetary magnetic field from a situs that is moving relative to the solar wind, such as a spacecraft or an astral body, such as the moon, having no magnetosphere that excludes the solar wind. Discrete plasma plumes are generated by plasma guns at the situs extending in opposite directions to one another and at an angle, preferably orthogonal, to the magnetic field direction of the solar wind plasma. The opposed plumes are separately electrically connected to their source by a low impedance connection. The relative movement between the plasma plumes and the solar wind plasma creates a voltage drop across the plumes which is tapped by placing the desired electrical load between the electrical connections of the plumes to their sources. A portion of the energy produced may be used in generating the plasma plumes for sustained operation.

The Deep-Sea Natural Products, Biogenic Polyphosphate (Bio-PolyP) and Biogenic Silica (Bio-Silica), as Biomimetic Scaffolds for Bone Tissue Engineering: Fabrication of a Morphogenetically-Active Polymer  

E-Print Network (OSTI)

Abstract: Bone defects in human, caused by fractures/nonunions or trauma, gain increasing impact and have become a medical challenge in the present-day aging population. Frequently, those fractures require surgical intervention which ideally relies on autografts or suboptimally on allografts. Therefore, it is pressing and likewise challenging to develop bone substitution materials to heal bone defects. During the differentiation of osteoblasts from their mesenchymal progenitor/stem cells and of osteoclasts from their hemopoietic precursor cells, a lineage-specific release of growth factors and a trans-lineage homeostatic cross-talk via signaling molecules take place. Hence, the major hurdle is to fabricate a template that is functioning in a way mimicking the morphogenetic, inductive role(s) of the native extracellular matrix. In the last few years, two naturally occurring polymers that are produced by deep-sea sponges, the biogenic polyphosphate (bio-polyP) and biogenic silica (bio-silica) have also been identified as promoting morphogenetic on both osteoblasts andMar.

Simplified scheme or radioactive plume calculations  

SciTech Connect

A simplified mathematical scheme to estimate external whole-body $gamma$ radiation exposure rates from gaseous radioactive plumes was developed for the Rio Blanco Gas Field Nuclear Stimulation Experiment. The method enables one to calculate swiftly, in the field, downwind exposure rates knowing the meteorological conditions and $gamma$ radiation exposure rates measured by detectors positioned near the plume source. The method is straightforward and easy to use under field conditions without the help of mini-computers. It is applicable to a wide range of radioactive plume situations. It should be noted that the Rio Blanco experiment was detonated on May 17, 1973, and no seep or release of radioactive material occurred. (auth)

OZONE PRODUCTION IN URBAN PLUMES.  

SciTech Connect

Ozone levels observed during a field campaign in Houston were significantly higher than that observed in Phoenix or Philadelphia. An examination of the slope of O{sub x} versus NO{sub z} in the urban plumes shows that NO{sub x} is used 2 to 3 times more efficiently in Houston as compared with Phoenix and Philadelphia. Representative values of OPEx are 7-12, 3, and 4, in Houston, Phoenix, and Philadelphia. Aircraft observations have been used to calculate P(O{sub 3})/P(NO{sub z}). Values in Houston are significantly higher than in Phoenix and Philadelphia. We show that P(O{sub 3})/P(NO{sub z}) is proportional to a VOC/NO{sub 2}-OH reactivity ratio. High values of P(O{sub 3})/P(NO{sub z}) in Houston are due to emissions of reactive olefins from the ship channel region. It is significant that high values of P(O{sub 3})/P(NO{sub z}) occur at NO{sub x} levels up to several 10's of ppb. Not only is the chemistry efficient but it will be long lasting. The occurrence of high NO{sub x} and high OPEx is fostered by the co-location of VOC and NO{sub x} sources in the Houston industrial areas.

PlumeSat: A Micro-Satellite Based Plume Imagery Collection Experiment  

DOE Green Energy (OSTI)

This paper describes a technical approach to cost-effectively collect plume imagery of boosting targets using a novel micro-satellite based platform operating in low earth orbit (LEO). The plume collection Micro-satellite or PlueSat for short, will be capable of carrying an array of multi-spectral (UV through LWIR) passive and active (Imaging LADAR) sensors and maneuvering with a lateral divert propulsion system to different observation altitudes (100 to 300 km) and different closing geometries to achieve a range of aspect angles (15 to 60 degrees) in order to simulate a variety of boost phase intercept missions. The PlumeSat will be a cost effective platform to collect boost phase plume imagery from within 1 to 10 km ranges, resulting in 0.1 to 1 meter resolution imagery of a variety of potential target missiles with a goal of demonstrating reliable plume-to-hardbody handover algorithms for future boost phase intercept missions. Once deployed on orbit, the PlumeSat would perform a series phenomenology collection experiments until expends its on-board propellants. The baseline PlumeSat concept is sized to provide from 5 to 7 separate fly by data collects of boosting targets. The total number of data collects will depend on the orbital basing altitude and the accuracy in delivering the boosting target vehicle to the nominal PlumeSat fly-by volume.

EVALUATION OF NATURAL AND IN-SITU REMEDIATION TECHNOLOGIES FOR A COAL-RELATED METALS PLUME  

SciTech Connect

Metals contamination exceeding drinking water standards (MCLs) is associated with acidic leachate generated from a coal pile runoff basin at the Savannah River Site (SRS) in Aiken, South Carolina. The metals plume extends over 100 acres with its' distal boundary about onehalf mile from the Savannah River. Based on the large plume extent and high dissolved iron and aluminum concentrations, conventional treatment technologies are likely to be ineffective and cost prohibitive. In-situ bioremediation using existing groundwater microbes is being evaluated as a promising alternative technology for effective treatment, along with consideration of natural attenuation of the lower concentration portions of the plume to meet remedial goals. Treatment of the high concentration portion of the groundwater plume by sulfate-reducing bacteria (SRB) is being evaluated through laboratory microcosm testing and a field-scale demonstration. Organic substrates are added to promote SRB growth. These bacteria use dissolved sulfate as an electron acceptor and ultimately precipitate dissolved metals as metal sulfides. Laboratory microcosm testing indicate SRB are present in groundwater despite low pH conditions, and that their growth can be stimulated by soybean oil and sodium lactate. The field demonstration consists of substrate injection into a 30-foot deep by 240-foot long permeable trench. Microbial activity is demonstrated by an increase in pH from 3 to 6 within the trench. Downgradient monitoring will be used to evaluate the effectiveness of SRB in reducing metal concentrations. Natural attenuation (NA) is being evaluated for the low concentration portion of the plume. A decrease in metal mobility can occur through a variety of abiotically and/or biotically mediated mechanisms. Quantification of these mechanisms is necessary to more accurately predict contaminant attenuation using groundwater transport models that have historically relied on simplified conservative assumptions. Result s from matched soil/porewater samples indicate higher soil/water partition coefficients (Kds) with increasing distance from the source. In addition, site-specific metals availability is being assessed using sequential extraction techniques, which more accurately represent environmental conditions as compared to default EPA extraction methods.

Infrared optical properties of diesel smoke plumes  

SciTech Connect

Far IR optical properties have been measured for smoke from diesel fires. Concentrations of both gaseous and particulate combustion products have been measured and chemical species contributing to the optical effects identified. To obtain these results, a variety of sampling instruments were lofted into large plumes on a mobile and open structure. The smoke plumes of diesel fires have been found to consist largely of carbonaceous material (in fibrous form) and heavy liquid hydrocarbons infused with the expected gaseous products of the combustion process. Strong attenuation at a wavelength of 10.6 {mu}m is found to be due largely to the carbonaceous aerosol. The absorption coefficient is typically {similar to}500 km{sup {minus}1} at 10 m from the source with a variable but often comparable total scattering coefficient. The extinction coefficient, normalized to the mass density of the aerosol in a unit volume of space, is found to be 1.2 m{sup 2}-g{sup {minus}1} with an estimated variance of 20%. Fluctuational spectra of the attenuation follow a form similar to turbulence spectra.

The Effect of Vertical Upward Flow on Thermal Plumes The Effect of Vertical Upward Flow on Thermal Plumes Speaker(s): Pierre S. Farrugia Date: November 18, 2010 - 12:05pm Location: 90-3122 Seminar Host/Point of Contact: David Lorenzetti Thermal plumes have been widely investigated in a variety of scenarios, including natural convection and stratified environments. The resulting theory may be used to predict ventilation flow rates in, for example, natural and displacement ventilation, and under-floor air distribution (UFAD) systems. However, there has been little effort in investigating how uniform upward flows affect the plume velocity, rate of growth, and thermal profile. Such situations can arise if, for example, the diffusers of a UFAD system are evenly distributed. In order to study such situations, analytical expressions for the velocity and temperature profiles of a plume

Dynamic balances within tropical plumes in a global barotropic model  

E-Print Network (OSTI)

Tropical plumes are a common synoptic scale feature over the Eastern Pacific associated with subtropical jet and ITCZ intensifications. Because of data sparseness, operational analysis has yielded little information of the details of the tropical plume formation process. Tropical plumes have been simulated in a global 200 mb shallow water model with a realistic basic state (Blackwell 1990). Diagnostic budgets were calculated based on model output for absolute vorticity, divergence, and kinetic energy. Also, the movement of the zero absolute vorticity isopleth during plume formation is examined. This information is compared for cases with plume formation, without plume formation, and the basic state. Budget results indicate the convergent forcing center, when located near a strong absolute vorticity gradient, creates an equatorial Rossby wave source. This source generates a large scale, quasi-stationary equatorial Rossby wave which, if located near the ambient eastern Pacific trough, strengthens this trough into the tropics. As the trough strengthens, it displaces the vorticity gradient equatorward into the cmvergence forcing region. This vorticity gradient encroaches upon the forcing region and creates a second Rossby wave source. This generates a second, smaller scale Rossby wave which propagates to the northeast along the axis of strong vorticity gradient. This Rossby wave is highly divergent in nature, due to the model's small Rossby radius of deformation. The accompanying train of convergence/divergence centers distorts the potential trough to create significant cross contour flow, which accelerates the subtropical jet to the east of the trough, resulting in a tropical plume. This study indicates the Rossby wave and accompanying cross contour and ageostrophic flow adequately explain the formation of all three key tropical plume features.

Chemical transformations may occur in the flue gas plume of coal-fired power plants (CFPP) that convert reactive gaseous mercury (RGM) into gaseous elemental mercury (GEM). Since the chemical form of inorganic Hg determines its solubility in water and therefore its deposition rate, understanding this chemistry has important implications for emission control. This fact sheet summarizes the state-of-knowledge of mercury chemistry, kinetics, and thermodynamics in CFPP plumes.

Propulsion research on the hybrid plume rocket  

DOE Green Energy (OSTI)

This report discusses the construction of a tandem mirror plasma propulsion facility, the numerical modelling of the hybrid plume exhaust, and rf heating of the plasma. A preliminary experiment of the ICRH (Ion Cyclotron Resonance Heating) heating of plasma ions was carried out. For 2.0 kW ECRH (Electron Cyclotron Resonance Heating) power injected into the central cell and 10 kW ICRH power into the end cell, the results obtained from the probe in the central cell are: n{sub e} = 2.5 {times} 10{sup 16} m{sup {minus}3} and T{sub e} = 80 eV (928,000 K) in the central cell. The estimated values in the end cell are: n{sub I} = 1.25 {times} 10{sup 17} m{sup {minus}3} and T{sub I} = 500 eV (5,797,000 K). The power conversion efficiency was about 80%. The results from time dependent 3-D three fluid numerical modeling indicate that a boundary layer can be formed. The formation of this layer is strongly dependent on neutral jet geometry and injection angle. The ICRH heating of plasma was modeled numerically and power absorption efficiency is about 50%. Analytical analyses was done on slab geometry. 12 refs., 20 figs., 3 tabs.

Updated Conceptual Model for the 300 Area Uranium Groundwater Plume  

SciTech Connect

The 300 Area uranium groundwater plume in the 300-FF-5 Operable Unit is residual from past discharge of nuclear fuel fabrication wastes to a number of liquid (and solid) disposal sites. The source zones in the disposal sites were remediated by excavation and backfilled to grade, but sorbed uranium remains in deeper, unexcavated vadose zone sediments. In spite of source term removal, the groundwater plume has shown remarkable persistence, with concentrations exceeding the drinking water standard over an area of approximately 1 km2. The plume resides within a coupled vadose zone, groundwater, river zone system of immense complexity and scale. Interactions between geologic structure, the hydrologic system driven by the Columbia River, groundwater-river exchange points, and the geochemistry of uranium contribute to persistence of the plume. The U.S. Department of Energy (DOE) recently completed a Remedial Investigation/Feasibility Study (RI/FS) to document characterization of the 300 Area uranium plume and plan for beginning to implement proposed remedial actions. As part of the RI/FS document, a conceptual model was developed that integrates knowledge of the hydrogeologic and geochemical properties of the 300 Area and controlling processes to yield an understanding of how the system behaves and the variables that control it. Recent results from the Hanford Integrated Field Research Challenge site and the Subsurface Biogeochemistry Scientific Focus Area Project funded by the DOE Office of Science were used to update the conceptual model and provide an assessment of key factors controlling plume persistence.

INDEPENDENT TECHNICAL REVIEW OF THE FOCUSED FEASIBILITY STUDY AND PROPOSED PLAN FOR DESIGNATED SOLID WASTE MANAGEMENT UNITS CONTRIBUTING TO THE SOUTHWEST GROUNDWATER PLUME AT THE PADUCAH GASEOUS DIFFUSION PLANT  

SciTech Connect

The U. S. Department of Energy (DOE) is currently developing a Proposed Plan (PP) for remediation of designated sources of chlorinated solvents that contribute contamination to the Southwest (SW) Groundwater Plume at the Paducah Gaseous Diffusion Plant (PGDP), in Paducah, KY. The principal contaminants in the SW Plume are trichloroethene (TCE) and other volatile organic compounds (VOCs); these industrial solvents were used and disposed in various facilities and locations at PGDP. In the SW plume area, residual TCE sources are primarily in the fine-grained sediments of the Upper Continental Recharge System (UCRS), a partially saturated zone that delivers contaminants downward into the coarse-grained Regional Gravel Aquifer (RGA). The RGA serves as the significant lateral groundwater transport pathway for the plume. In the SW Plume area, the four main contributing TCE source units are: (1) Solid Waste Management Unit (SWMU) 1 / Oil Landfarm; (2) C-720 Building TCE Northeast Spill Site (SWMU 211A); (3) C-720 Building TCE Southeast Spill Site (SWMU 211B); and (4) C-747 Contaminated Burial Yard (SWMU 4). The PP presents the Preferred Alternatives for remediation of VOCs in the UCRS at the Oil Landfarm and the C-720 Building spill sites. The basis for the PP is documented in a Focused Feasibility Study (FFS) (DOE, 2011) and a Site Investigation Report (SI) (DOE, 2007). The SW plume is currently within the boundaries of PGDP (i.e., does not extend off-site). Nonetheless, reasonable mitigation of the multiple contaminant sources contributing to the SW plume is one of the necessary components identified in the PGDP End State Vision (DOE, 2005). Because of the importance of the proposed actions DOE assembled an Independent Technical Review (ITR) team to provide input and assistance in finalizing the PP.

Calculating the probability of injected carbon dioxide plumes encountering faults  

Science Conference Proceedings (OSTI)

One of the main concerns of storage in saline aquifers is leakage via faults. In the early stages of site selection, site-specific fault coverages are often not available for these aquifers. This necessitates a method using available fault data to estimate the probability of injected carbon dioxide encountering and migrating up a fault. The probability of encounter can be calculated from areal fault density statistics from available data, and carbon dioxide plume dimensions from numerical simulation. Given a number of assumptions, the dimension of the plume perpendicular to a fault times the areal density of faults with offsets greater than some threshold of interest provides probability of the plume encountering such a fault. Application of this result to a previously planned large-scale pilot injection in the southern portion of the San Joaquin Basin yielded a 3% and 7% chance of the plume encountering a fully and half seal offsetting fault, respectively. Subsequently available data indicated a half seal-offsetting fault at a distance from the injection well that implied a 20% probability of encounter for a plume sufficiently large to reach it.

The portion of the rich air/fuel mixture remaining in the cavity of the generator is then ignited to provide a secondary jet, comprising incomplete combustion products which are injected into the cylinder to initiate combustion in the already formed turbulent jet plume. Formation of the turbulent jet plume in the head space of the cylinder prior to ignition has been found to yield a higher maximum combustion pressure in the cylinder, as well as shortening the time period to attain such a maximum pressure.

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

Numerical modeling of plasma plume evolution against ambient background gas in laser blow off experiments  

Science Conference Proceedings (OSTI)

Two dimensional numerical modelling based on simplified hydrodynamic evolution for an expanding plasma plume (created by laser blow off) against an ambient background gas has been carried out. A comparison with experimental observations shows that these simulations capture most features of the plasma plume expansion. The plume location and other gross features are reproduced as per the experimental observation in quantitative detail. The plume shape evolution and its dependence on the ambient background gas are in good qualitative agreement with the experiment. This suggests that a simplified hydrodynamic expansion model is adequate for the description of plasma plume expansion.

Subsurface Hybrid Power Options for Oil & Gas Production at Deep Ocean Sites  

Science Conference Proceedings (OSTI)

An investment in deep-sea (deep-ocean) hybrid power systems may enable certain off-shore oil and gas exploration and production. Advanced deep-ocean drilling and production operations, locally powered, may provide commercial access to oil and gas reserves otherwise inaccessible. Further, subsea generation of electrical power has the potential of featuring a low carbon output resulting in improved environmental conditions. Such technology therefore, enhances the energy security of the United States in a green and environmentally friendly manner. The objective of this study is to evaluate alternatives and recommend equipment to develop into hybrid energy conversion and storage systems for deep ocean operations. Such power systems will be located on the ocean floor and will be used to power offshore oil and gas exploration and production operations. Such power systems will be located on the oceans floor, and will be used to supply oil and gas exploration activities, as well as drilling operations required to harvest petroleum reserves. The following conceptual hybrid systems have been identified as candidates for powering sub-surface oil and gas production operations: (1) PWR = Pressurized-Water Nuclear Reactor + Lead-Acid Battery; (2) FC1 = Line for Surface O{sub 2} + Well Head Gas + Reformer + PEMFC + Lead-Acid & Li-Ion Batteries; (3) FC2 = Stored O2 + Well Head Gas + Reformer + Fuel Cell + Lead-Acid & Li-Ion Batteries; (4) SV1 = Submersible Vehicle + Stored O{sub 2} + Fuel Cell + Lead-Acid & Li-Ion Batteries; (5) SV2 = Submersible Vehicle + Stored O{sub 2} + Engine or Turbine + Lead-Acid & Li-Ion Batteries; (6) SV3 = Submersible Vehicle + Charge at Docking Station + ZEBRA & Li-Ion Batteries; (7) PWR TEG = PWR + Thermoelectric Generator + Lead-Acid Battery; (8) WELL TEG = Thermoelectric Generator + Well Head Waste Heat + Lead-Acid Battery; (9) GRID = Ocean Floor Electrical Grid + Lead-Acid Battery; and (10) DOC = Deep Ocean Current + Lead-Acid Battery.

This study reports direct detection by the Cassini plasma spectrometer of freshly-produced water-group ions (O{sup +}, OH{sup +}, H{sub 2}O{sup +}, H{sub 3}O{sup +}) and heavier water dimer ions (H{sub x}O{sub 2}{sup +}) very close to Enceladus and where the plasma begins to emerge from the Enceladus plume The data wcre obtained during two close (52 and 25 km) flybys of Enceladus in 2008, and are similar to ion data in cometary comas. The ions are observed in detectors looking in the Cassini ram direction at energies consistent with the Cassini speed, indicating a nearly stagnant plasma flow in the plume. North of Enceladus the plasma slowing commences about 4 to 6 Enceladus radii away, while south of Enccladus signatures ofthe interaction are detected as far as 22 Enceladus radii away.

Joint reconstructions of CO2 plumes using a Markov Chain Monte Carlo approach  

SciTech Connect

We describe a stochastic inversion method for mapping subsurface regions where CO{sub 2} saturation is changing. The technique combines prior information with measurements of injected CO{sub 2} volume, reservoir deformation and electrical resistivity. Bayesian inference and a Metropolis simulation algorithm form the basis for this approach. The method can (a) jointly reconstruct disparate data types such as surface or subsurface tilt, electrical resistivity, and injected CO{sub 2} volume measurements, (b) provide quantitative measures of the result uncertainty, (c) identify competing models when the available data are insufficient to definitively identify a single optimal model and (d) rank the alternative models based on how well they fit available data. We use measurements collected during CO{sub 2} injection for enhanced oil recovery to illustrate the method's performance. The stochastic inversions provide estimates of the most probable location, shape, volume of the plume and most likely CO{sub 2} saturation. The results suggest that the method can reconstruct data with poor signal to noise ratio.

Effect of a plume reduction in segmented electrode Hall thruster  

DOE Green Energy (OSTI)

A segmented electrode, which is placed at the thruster exit, is shown to affect thruster operation in several ways, whether the electrode produce low emission current or no emission current, although there appear to be advantages to the more emissive segmented electrode. Measured by plume divergence, the performance of Hall thruster operation, even with only one power supply, can approach or surpass that of non segmented operation over a range of parameter regimes, including the low gas rate regime. This allows the flexibility in operation of segmented electrode thrusters in variable thrust regimes.

GIS and plume dispersion modeling for population exposure assessment  

E-Print Network (OSTI)

The use of Pollutant Plume Dispersion Models is widespread in the evaluation of point sources of air pollution. These models provide valuable insight into the concentration and dispersion of hazardous materials throughout the atmosphere. Traditional methods of dispersion modeling for the permitting of new sources and the monitoring of existing sources have allowed much room for error in terms of the effect of the pollutants on nearby populations (Hardikar, 1995). The capabilities of GIS technology offer an improved method of conducting air quality modeling for permitting, remediation studies, and environmental monitoring. GIS has the ability to develop and manage a comprehensive database of model output, map layers, and demographic data that can prove extremely valuable in the modeling process. This data can serve to extend the capabilities of air pollution dispersion modeling from mere estimation of concentrations to comprehensive exposure assessment of neighboring populations (Lowry, et al. 1995, Maslia, et al. 1994). A study of the Monticello power plant in northeast Texas was conducted using the SCREEN3 mathematical plume dispersion model, US Census Bureau demographic data, and a GIS to examine the effects of the plant output on the people living in the seven county area surrounding the plant.

Experimental and computational study of complex shockwave dynamics in laser ablation plumes in argon atmosphere  

SciTech Connect

We investigated spatio-temporal evolution of ns laser ablation plumes at atmospheric pressure, a favored condition for laser-induced breakdown spectroscopy and laser-ablation inductively coupled plasma mass-spectrometry. The 1064 nm, 6 ns pulses from a Nd:YAG laser were focused on to an Al target and the generated plasma was allowed to expand in 1 atm Ar. The hydrodynamic expansion features were studied using focused shadowgraphy and gated 2 ns self-emission visible imaging. Shadowgram images showed material ejection and generation of shock fronts. A secondary shock is observed behind the primary shock during the time window of 100-500 ns with instabilities near the laser cone angle. By comparing the self-emission images obtained using fast photography, it is concluded that the secondary shocks observed in the shadowgraphy were generated by fast moving target material. The plume front estimates using fast photography exhibited reasonable agreement with data obtained from shadowgraphy at early times {<=}400 ns. However, at later times, fast photography images showed plume confinement while the shadowgraphic images showed propagation of the plume front even at greater times. The structure and dynamics of the plume obtained from optical diagnostic tools were compared to numerical simulations. We have shown that the main features of plume expansion in ambient Ar observed in the experiments can be reproduced using a continuum hydrodynamics model which provided valuable insight into the expansion dynamics and shock structure of the plasma plume.

Initial parametric study of the flammability of plume releases in Hanford waste tanks  

SciTech Connect

This study comprised systematic analyses of waste tank headspace flammability following a plume-type of gas release from the waste. First, critical parameters affecting plume flammability were selected, evaluated, and refined. As part of the evaluation the effect of ventilation (breathing) air inflow on the convective flow field inside the tank headspace was assessed, and the magnitude of the so-called {open_quotes}numerical diffusion{close_quotes} on numerical simulation accuracy was investigated. Both issues were concluded to be negligible influences on predicted flammable gas concentrations in the tank headspace. Previous validation of the TEMPEST code against experimental data is also discussed, with calculated results in good agreements with experimental data. Twelve plume release simulations were then run, using release volumes and flow rates that were thought to cover the range of actual release volumes and rates. The results indicate that most plume-type releases remain flammable only during the actual release ends. Only for very large releases representing a significant fraction of the volume necessary to make the entire mixed headspace flammable (many thousands of cubic feet) can flammable concentrations persist for several hours after the release ends. However, as in the smaller plumes, only a fraction of the total release volume is flammable at any one time. The transient evolution of several plume sizes is illustrated in a number of color contour plots that provide insight into plume mixing behavior.

Plume splitting and rebounding in a high-intensity CO{sub 2} laser induced air plasma  

Science Conference Proceedings (OSTI)

The dynamics of plasma plume formed by high-intensity CO{sub 2} laser induced breakdown of air at atmospheric pressure is investigated. The laser wavelength is 10.6 {mu}m. Measurements were made using 3 ns gated fast photography as well as space and time resolved optical emission spectroscopy. The behavior of the plasma plume was studied with a laser energy of 3 J and 10 J. The results show that the evolution of the plasma plume is very complicated. The splitting and rebounding of the plasma plume is observed to occur early in the plumes history.

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

E-Print Network (OSTI)

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

FINAL TECHNICAL REPORT-THE ECOLOGY AND GENOMICS OF CO2 FIXATIION IN OCEANIC RIVER PLUMES  

SciTech Connect

Oceanic river plumes represent some of the most productive environments on Earth. As major conduits for freshwater and nutrients into the coastal ocean, their impact on water column ecosystems extend for up to a thousand km into oligotrophic oceans. Upon entry into the oceans rivers are tremendous sources of CO2 and dissolved inorganic carbon (DIC). Yet owing to increased light transmissivity from sediment deposition coupled with the influx of nutrients, dramatic CO2 drawdown occurs, and plumes rapidly become sinks for CO2. Using state-of-the-art gene expression technology, we have examined the molecular biodiversity of CO2 fixation in the Mississippi River Plume (MRP; two research cruises) and the Orinoco River Plume (ORP; one cruise). When the MRP extends far into the Gulf because of entrainment with the Loop Current, MRP production (carbon fixation) can account for up to 41% of the surface production in the Gulf of Mexico. Nearer-shore plume stations (high plume, salinity< 32 ppt) had tremendous CO2 drawdown that was correlated to heterokont (principally diatom) carbon fixation gene expression. The principal form of nitrogen for this production based upon 15N studies was urea, believed to be from anthropogenic origin (fertilizer) from the MRP watershed. Intermediate plume environments (salinity 34 ppt) were characterized by high levels of Synechococcuus carbon fixation that was fueled by regenerated ammonium. Non-plume stations were characterized by high light Prochlorococcus carbon fixation gene expression that was positively correlated with dissolved CO2 concentrations. Although data from the ORP cruise is still being analyzed, some similarities and striking differences were found between the ORP and MRP. High levels of heterokont carbon fixation gene expression that correlated with CO2 drawdown were observed in the high plume, yet the magnitude of this phenomenon was far below that of the MRP, most likely due to the lower levels of anthropogenic nutrient input. The offshore ORP was characterized by haptophyte and in places Prochlorococcus carbon fixation gene expression in surface water, with greater heterokont rbcL RNA at SCM depths. MODIS satellite chlorophyll-a data implied a plume of high chlorophyll water far into the eastern Caribbean, yet field observations did not support this, most likely because of high levels of colored dissolved organic matter (cDOM) in the ORP. The presence of pelagic nitrogen fixers (Trichodesmium and cyanobacterial diatom endosymbionts) most likely provided N for the offshore MRP production. The results underscore the importance of oceanic river plumes as sinks for CO2 and the need for their incorporation in global carbon models as well as estimates of CO2 sequestration.

EFFICIENCY OF OZONE PRODUCTION IN THE HOUSTON PLUME.  

SciTech Connect

Ozone levels observed during a field campaign in Houston were significantly higher than that observed in Phoenix or Philadelphia. An examination of the slope of O{sub x} versus NO{sub z} in the urban plumes shows that NO{sub x} is used 2 to 3 times more efficiently in Houston as compared with Phoenix and Philadelphia. Representative values of OPEx are 7-12, 3, and 4, in Houston, Phoenix, and Philadelphia. Aircraft observations have been used to calculate P(O{sub 3})/P(NO{sub z}). Values in Houston are significantly higher than in Phoenix and Philadelphia. We show that P(O{sub 3})/P(NO{sub z}) is proportional to a VOC/NO{sub 2}-OH reactivity ratio. High values of P(O{sub 3})/P(NO{sub z}) in Houston are due to emissions of reactive olefins from the ship channel region. It is significant that high values of P(O{sub 3})/P(NO{sub z}) occur at NO{sub x} levels up to several 10's of ppb. Not only is the chemistry efficient but it will be long lasting. The occurrence of high NO{sub x} and high OPEx is fostered by the co-location of VOC and NO{sub x} sources in the Houston industrial areas.

Nearer-shore plume stations (high plume, salinityORP cruise is still being analyzed, some similarities and striking differences were found between the ORP and MRP. High levels of heterokont carbon fixation gene expression that correlated with CO2 drawdown were observed in the high plume, yet the magnitude of this phenomenon was far below that of the MRP, most likely due to the lower levels of anthropogenic nutrient input. The offshore ORP was characterized by haptophyte and in places Prochlorococcus carbon fixation gene expression in surface water, with greater heterokont rbcL RNA at SCM depths. MODIS satellite chlorophyll-a data implied a plume of high chlorophyll water far into the eastern Caribbean, yet field observations did not support this, most likely because of high levels of colored dissolved organic matter (cDOM) in the ORP. The presence of pelagic nitrogen fixers (Trichodesmium and cyanobacterial diatom endosymbionts) most likely provided N for the offshore MRP production. The results underscore the importance of oceanic river plumes as sinks for CO2 and the need for their incorporation in global carbon models as well as estimates of CO2 sequestration.

QUIESCENT PROMINENCE DYNAMICS OBSERVED WITH THE HINODE SOLAR OPTICAL TELESCOPE. I. TURBULENT UPFLOW PLUMES  

SciTech Connect

Hinode/Solar Optical Telescope (SOT) observations reveal two new dynamic modes in quiescent solar prominences: large-scale (20-50 Mm) 'arches' or 'bubbles' that 'inflate' from below into prominences, and smaller-scale (2-6 Mm) dark turbulent upflows. These novel dynamics are related in that they are always dark in visible-light spectral bands, they rise through the bright prominence emission with approximately constant speeds, and the small-scale upflows are sometimes observed to emanate from the top of the larger bubbles. Here we present detailed kinematic measurements of the small-scale turbulent upflows seen in several prominences in the SOT database. The dark upflows typically initiate vertically from 5 to 10 Mm wide dark cavities between the bottom of the prominence and the top of the chromospheric spicule layer. Small perturbations on the order of 1 Mm or less in size grow on the upper boundaries of cavities to generate plumes up to 4-6 Mm across at their largest widths. All plumes develop highly turbulent profiles, including occasional Kelvin-Helmholtz vortex 'roll-up' of the leading edge. The flows typically rise 10-15 Mm before decelerating to equilibrium. We measure the flowfield characteristics with a manual tracing method and with the Nonlinear Affine Velocity Estimator (NAVE) 'optical flow' code to derive velocity, acceleration, lifetime, and height data for several representative plumes. Maximum initial speeds are in the range of 20-30 km s{sup -1}, which is supersonic for a {approx}10,000 K plasma. The plumes decelerate in the final few Mm of their trajectories resulting in mean ascent speeds of 13-17 km s{sup -1}. Typical lifetimes range from 300 to 1000 s ({approx}5-15 minutes). The area growth rate of the plumes (observed as two-dimensional objects in the plane of the sky) is initially linear and ranges from 20,000 to 30,000 km{sup 2} s{sup -1} reaching maximum projected areas from 2 to 15 Mm{sup 2}. Maximum contrast of the dark flows relative to the bright prominence plasma in SOT images is negative and ranges from -10% for smaller flows to -50% for larger flows. Passive scalar 'cork movies' derived from NAVE measurements show that prominence plasma is entrained by the upflows, helping to counter the ubiquitous downflow streams in the prominence. Plume formation shows no clear temporal periodicity. However, it is common to find 'active cavities' beneath prominences that can spawn many upflows in succession before going dormant. The mean flow recurrence time in these active locations is roughly 300-500 s (5-8 minutes). Locations remain active on timescales of tens of minutes up to several hours. Using a column density ratio measurement and reasonable assumptions on plume and prominence geometries, we estimate that the mass density in the dark cavities is at most 20% of the visible prominence density, implying that a single large plume could supply up to 1% of the mass of a typical quiescent prominence. We hypothesize that the plumes are generated from a Rayleigh-Taylor instability taking place on the boundary between the buoyant cavities and the overlying prominence. Characteristics, such as plume size and frequency, may be modulated by the strength and direction of the cavity magnetic field relative to the prominence magnetic field. We conclude that buoyant plumes are a source of quiescent prominence mass as well as a mechanism by which prominence plasma is advected upward, countering constant gravitational drainage.

Showmaker-Levy 9 and plume-forming collisions on Earth  

SciTech Connect

Computational models for the July, 1994 collision of comet Shoemaker-Levy 9 with Jupiter have provided a framework for interpreting the observational data. Imaging, photometry, and spectroscopy data from ground-based, Hubble Space Telescope, and Galileo spacecraft instruments are consistent with phenomena that were dominated by the generation of incandescent fireballs that were ballistically ejected to high altitudes, where they formed plumes that subsequently collapsed over large areas of Jupiter`s atmosphere. Applications of similar computational models to collisions into Earth`s atmosphere show that a very similar sequence of events should take place for NEO impacts with energies as low as 3 megatons, recurring on 100 year timescales or less. This result suggests that the 1908 Tunguska event was a plume-forming atmospheric explosion, and that some of the phenomena associated with it might be related to the ejection and collapse of a high plume. Hazards associated with plume growth and collapse should be included in the evaluation of the impact threat to Earth, and opportunities should be sought for observational validation of atmospheric impact models by exploiting data already being collected from the natural flux of multi-kiloton to megaton sized objects that constantly enter Earth`s atmosphere on annual to decadal timescales.

Penetration of buoyancy driven current due to a wind forced river plume  

E-Print Network (OSTI)

The long term response of a plume associated with freshwater penetration into ambient, ocean water under upwelling favorable winds is studied using the Regional Ocean Modeling System (ROMS) in an idealized domain. Three different cases were examined, including a shore perpendicular source and shore parallel source with steady winds, and a shore perpendicular source with oscillating alongshore winds. Freshwater flux is used to define plume penetration. Alongshore penetration of buoyant currents is proportional to freshwater input and inversely proportional to upwelling wind stress strength. Strong wind more quickly prevents fresh waters penetration. Under upwelling favorable winds, the plume is advected offshore by Ekman transport as well as upcoast by the mean flow. This causes the bulge to detach from the coast and move to upcoast and offshore with a 45 degree angle. The path of the bulge is roughly linear, and is independent of wind strength. The bulge speed has a linear relationship with the wind stress strength, and it matches the expected speed based on Ekman theory. Sinusoidal wind leads to sequential upwelling and downwelling events. The plume has an asymmetric response to upwelling and downwelling and fresh water flux is changed immediately by wind. During downwelling, the downcoast fresh water transport is greatest, while it is reduced during upwelling. Background mean flow in the downcoast direction substantially increases alongshore freshwater transport.

Utah Heavy Oil Program  

Science Conference Proceedings (OSTI)

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

Carbon flow and ecosystem dynamics in the Mississippi River plume described by inverse analysis  

E-Print Network (OSTI)

Planktonic ecosystem dynamics in the buoyant Mississippi River plume were investigated using inverse analysis, a technique that incorporates data describing ecosystem processes and calculates rates of unknown trophic flows and sedimentation in the plume ecosystem. The waters receiving the Mississippi River were divided into four subregions connected by water flow to discretize the gradient of ecosystem properties as river water mixed with ocean water. Each subregion was represented by eight interconnected compartments that were linked to adjacent subregions by advective carbon flow. Models were produced for 4 seasons. Solutions for three seasons (spring, summer, and fall) showed a small region of net autotrophy associated with mid-salinity waters (15-29 psu), surrounded by a larger region of net heterotrophic waters where production did not meet respiratory carbon demand. In addition to moving more than 20% of total plume primary productivity out of the study region, westward water flow moved excess organic carbon from autotrophic regions to heterotrophic regions. In contrast, the winter result indicated a plume that was net-heterotrophic in all 4 subregions with high aerobic bacterial respiration and relatively low primary production that did not meet respiratory demand. Inputs of riverine DOC and carbon from resuspended sediments were required to make up the deficit. Sedimentation of organic carbon was linked to primary production in the mid-salinity regions of the plume, with strongest sedimentation from the productive mid-salinity regions during most of the year. Sedimentation was enhanced beneath less productive, higher salinity areas, due to inputs of organic carbon advected from mid-salinity regions. During winter organic carbon sedimentation was calculated to be zero. The models indicated that a dynamic relationship between primary production and sedimentation exists and provide a good starting point for future development of models which directly address the relationships between nutrient inputs, primary production, sedimentation, and hypoxia in the economically and environmental important regions of the Louisiana Shelf.

Field Instruments for Real Time In-Situ Crude Oil Concentration Measurements  

E-Print Network (OSTI)

The Texas Water Resources Institute awarded a Mill Scholarship to M.C. Sterling, Jr in 2002. This project describes five sensors for rapid monitoring of crude oil concentrations in an aquatic system. These measurements are critical for monitoring plume transport. They are also useful for estimating polycyclic aromatic hydrocarbons (PAH) exposure concentrations as a component of toxicity risk assessments. A submersible multi-angle laser scattering instrument (LISST-100, Sequoia Instruments), an ex-situ single wavelength fluorometer (AU-10 field fluorometer, Turner Designs), an in-situ single wavelength fluorometer (Flashlamp, WET Labs), and two in-situ multiple wavelength fluorometers (ECO-FL3 and SAFire, WET Labs) are evaluated for sensitivity and bias. For each instrument, a brief discussion of its operating principles is presented. Crude oil emulsions of various concentrations were analyzed using the above instruments. The implications of potential interferences and instrument limits are discussed relative to their importance for real time monitoring of crude oil spills.

Oil shale commercialization study  

SciTech Connect

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

Crude Oil Analysis Database  

DOE Data Explorer (OSTI)

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

Shale oil: process choices  

SciTech Connect

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

Oil from rock  

SciTech Connect

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

Oil spill response resources  

E-Print Network (OSTI)

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

Case study analysis of biomass burning plumes observed over Brazil during SAMBBA, September 2012  

Science Conference Proceedings (OSTI)

Biomass burning is a huge source of atmospheric aerosols and is poorly understood leading to large uncertainties in estimates of radiative forcing of climate. Aerosols have both a direct effect on climate by reflecting and absorbing solar radiation and an indirect effect by acting as cloud condensation nuclei (CCN) and ice nuclei (IN). Biomass burning aerosols are produced from burning of vegetation with the vast majority occurring in the tropics. This research presents data collected during the aircraft campaign of the South American Biomass Burning Analysis (SAMBBA) project during September and October 2012. A smouldering rainforest fire and a flaming savannah-like fire were selected for in-depth case studies of the atmospheric plume constituents and provide a comparison between the two fire types.

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

SciTech Connect

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

Why solar oil shale retorting produces more oil  

DOE Green Energy (OSTI)

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

TREATABILITY STUDY FOR EDIBLE OIL DEPLOYMENT FOR ENHANCED CVOC ATTENUATION FOR T-AREA, SAVANNAH RIVER SITE  

SciTech Connect

Groundwater beneath T-Area, a former laboratory and semiworks operation at the Department of Energy (DOE) Savannah River Site (SRS), is contaminated by chlorinated solvents (cVOCs). Since the contamination was detected in the 1980s, the cVOCs at T-Area have been treated by a combination of soil vapor extraction and groundwater pump and treat. The site received approval to temporarily discontinue the active groundwater treatment and implement a treatability study of enhanced attenuation - an engineering and regulatory strategy that has recently been developed by DOE and the Interstate Technology and Regulatory Council (ITRC 2007). Enhanced attenuation uses active engineering solutions to alter the target site in such a way that the contaminant plume will passively stabilize and shrink and to document that the action will be effective, timely, and sustainable. The paradigm recognizes that attenuation remedies are fundamentally based on a mass balance. Thus, long-term plume dynamics can be altered either by reducing the contaminant loading from the source or by increasing the rate of natural attenuation processes within all, or part of, the plume volume. The combination of technologies that emerged for T-Area included: (1) neat (pure) vegetable oil deployment in the deep vadose zone in the former source area, (2) emulsified vegetable oil deployment within the footprint of the groundwater plume, and (3) identification of attenuation mechanisms and rates for the distal portion of the plume. In the first part, neat oil spreads laterally forming a thin layer on the water table to intercept and reduce future cVOC loading (via partitioning) and reduce oxygen inputs (via biostimulation). In the second and third parts, emulsified oil forms active bioremediation reactor zones within the plume footprint to degrade existing groundwater contamination (via reductive dechlorination and/or cometabolism) and stimulates long-term attenuation capacity in the distal plume (via cometabolism). For TArea, the enhanced attenuation development process proved to be a powerful tool in developing a strategy that provides a high degree of performance while minimizing adverse collateral impacts of the remediation (e.g., energy use and wetland damage) and minimizing life-cycle costs. As depicted in Figure 1, Edible oil deployment results in the development of structured geochemical zones and serves to decrease chlorinated compound concentrations in two ways: (1) physical sequestration, which reduces effective aqueous concentration and mobility; and (2) stimulation of anaerobic, abiotic and cometabolic degradation processes. In the central deployment area, contaminant initially partitions into the added oil phase. Biodegradation of the added organic substrate depletes the aquifer of oxygen and other terminal electron acceptors and creates conditions conducive to anaerobic degradation processes. The organic substrate is fermented to produce hydrogen, which is used as an electron donor for anaerobic dechlorination by organisms such as Dehalococcoides. Daughter products leaving the central treatment zone are amenable to aerobic oxidation. Further, the organic compounds leaving the central deployment zone (e.g., methane and propane) stimulate and enhance down gradient aerobic cometabolism which degrades both daughter compounds and several parent cVOCs. Figure 1 depicts TCE concentration reduction processes (labeled in green) along with their corresponding breakdown products in a structured geochemical zone scenario. A consortium of bacteria with the same net effect of Dehalococcoides may be present in the structured geochemical zones leading to the degradation of TCE and daughter products. Figure 2 shows a schematic of the documented cVOC degradation processes in both the anaerobic and aerobic structured geochemical zones. Specific aerobic and anaerobic bacteria and their degradation pathways are also listed in the diagram and have either been confirmed in the field or the laboratory. See references in the bibliography in Section 11.

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

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

SciTech Connect

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

Integration of Predicted Atmospheric Contaminant Plumes into ArcView GIS  

Science Conference Proceedings (OSTI)

The Savannah River National Laboratory (SRNL) plays a key role in emergency response scenarios in which there may be a release of atmospheric chemical or radiological contamination at the DOE's Savannah River Site (SRS). Meteorologists at SRNL use a variety of tools to predict the path of the plume and levels of contamination along the path. These predictions are used to guide field teams that take sample measurements for verification. Integration of these predicted plumes as well as field measurements into existing Geographic Information System (GIS) interactive maps provides key additional information for decision makers during an emergency. In addition, having this information in GIS format facilitates sharing the information with other agencies that use GIS. In order to be useful during an emergency, an application for converting predictions or measurements into GIS format must be automated and simple to use. Thus, a key design goal in developing such applications is ease of use. Simple menu selections and intuitive forms with graphical user interfaces are used to accomplish this goal. Applications have been written to convert two different predictive code results into ArcView GIS. Meteorologists at SRNL use the Puff/Plume code, which is tied to real-time wind data, to predict the direction and spread of the atmospheric plume for early assessment. The calculated circular puffs are converted into an ArcView polygon shapefile with attributes for predicted time, dose, and radius of the puff. The meteorologists use the more sophisticated Lagrangian Particle Dispersion Model (LPDM) to predict particle dispersion and deposition. The calculational grid is brought into ArcView as a point shapefile and then interpolated to ARC GRID format using Spatial Analyst. This GRID can then be contoured into a line shapefile, which is easily shared with other agencies. The deposition grid is also automatically contoured for values that correspond to FDA Derived Intervention Levels for beef, produce, and dairy products. Decision makers at SRS routinely use these predicted plumes to direct field teams. In the case of a strong release, this information can be used to decide whether to evacuate a particular area. Having this information in GIS format may aid the decision maker because other infrastructure information can be overlaid with geographic reference.

Heavy crude oil recovery  

SciTech Connect

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

Corrosivity Of Pyrolysis Oils  

SciTech Connect

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

Oil shale data book  

SciTech Connect

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

Market assessment for shale oil  

DOE Green Energy (OSTI)

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

Estimating Plume Volume for Geologic Storage of CO2 in Saline Aquifers  

Science Conference Proceedings (OSTI)

Typically, when a new subsurface flow and transport problem is first being considered, very simple models with a minimal number of parameters are used to get a rough idea of how the system will evolve. For a hydrogeologist considering the spreading of a contaminant plume in an aquifer, the aquifer thickness, porosity, and permeability might be enough to get started. If the plume is buoyant, aquifer dip comes into play. If regional groundwater flow is significant or there are nearby wells pumping, these features need to be included. Generally, the required parameters tend to be known from pre-existing studies, are parameters that people working in the field are familiar with, and represent features that are easy to explain to potential funding agencies, regulators, stakeholders, and the public. The situation for geologic storage of carbon dioxide (CO{sub 2}) in saline aquifers is quite different. It is certainly desirable to do preliminary modeling in advance of any field work since geologic storage of CO{sub 2} is a novel concept that few people have much experience with or intuition about. But the parameters that control CO{sub 2} plume behavior are a little more daunting to assemble and explain than those for a groundwater flow problem. Even the most basic question of how much volume a given mass of injected CO{sub 2} will occupy in the subsurface is non-trivial. However, with a number of simplifying assumptions, some preliminary estimates can be made, as described below. To make efficient use of the subsurface storage volume available, CO{sub 2} density should be large, which means choosing a storage formation at depths below about 800 m, where pressure and temperature conditions are above the critical point of CO{sub 2} (P = 73.8 bars, T = 31 C). Then CO{sub 2} will exist primarily as a free-phase supercritical fluid, while some CO{sub 2} will dissolve into the aqueous phase.

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

Futures oil market outlook  

Science Conference Proceedings (OSTI)

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

Transmission of light in deep sea water at the site of the Antares neutrino telescope  

E-Print Network (OSTI)

The ANTARES neutrino telescope is a large photomultiplier array designed to detect neutrino-induced upward-going muons by their Cherenkov radiation. Understanding the absorption and scattering of light in the deep Mediterranean is fundamental to optimising the design and performance of the detector. This paper presents measurements of blue and UV light transmission at the ANTARES site taken between 1997 and 2000. The derived values for the scattering length and the angular distribution of particulate scattering were found to be highly correlated, and results are therefore presented in terms of an absorption length lambda_abs and an effective scattering length lambda_sct^eff. The values for blue (UV) light are found to be lambda_abs ~ 60(26) m, lambda_sct^eff ~ 265(122) m, with significant (15%) time variability. Finally, the results of ANTARES simulations showing the effect of these water properties on the anticipated performance of the detector are presented.

Constraining the reservoir model of an injected CO2 plume with crosswell CASSM at the Frio-II brine plot  

SciTech Connect

Crosswell CASSM (continuous active-source seismic monitoring) data was acquired as part of the Frio-II brine pilot CO{sub 2} injection experiment. To gain insight into the CO{sub 2} plume evolution, we have integrated the 3D multiphase flow modeling code TOUGH2 with seismic simulation codes via a petrophysical model that predicts seismic velocity for a given CO{sub 2} saturation. Results of forward seismic modeling based on the CO{sub 2} saturation distribution produced by an initial TOUGH2 model compare poorly with the CASSM data, indicating that the initial flow model did not capture the actual CO{sub 2} plume dynamics. Updates to the TOUGH2 model required to better match the CASSM field data indicate vertical flow near the injection well, with increased horizontal plume growth occurring at the top of the reservoir sand. The CASSM continuous delay time data are ideal for constraining the modeled spatiotemporal evolution of the CO{sub 2} plume and allow improvement in reservoir model and estimation of CO{sub 2} plume properties.

Formation of sheet plumes, current coils, and helical magnetic fields in a spherical magnetohydrodynamic dynamo  

Science Conference Proceedings (OSTI)

Aiming at understanding of magnetic field generation process in rapidly rotating stars and planets represented by the Earth, computer simulations of magnetohydrodynamic (MHD) dynamo were performed in a rotating spherical shell geometry. Thermal convection and dynamo process with Ekman number of the order of 10{sup -7} were studied. New structures of convection motion, dynamo-generated electrical current, and magnetic field are found. The flow is organized as a set of thin, sheet-like plumes. The current is made of small-scale coil structure with magnetic flux tubes within each of the coil. These flux tubes are connected each other to form a large scale helical magnetic field structure.

Oil recovery process  

Science Conference Proceedings (OSTI)

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

Chemically enhanced oil recovery  

Science Conference Proceedings (OSTI)

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

Oil/gas collector/separator for underwater oil leaks  

DOE Patents (OSTI)

This invention is comprised of an oil/gas collector/separator for recovery of oil leaking, for example, from an offshore or underwater oil well. The separator is floated over the point of the leak and tethered in place so as to receive oil/gas floating, or forced under pressure, toward the water surface from either a broken or leaking oil well casing, line, or sunken ship. 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.

Process for preparing lubricating oil from used waste lubricating oil  

DOE Patents (OSTI)

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

Shale oil cracking. 2. Effect on oil composition  

DOE Green Energy (OSTI)

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

Quantitative measurement of atomic sodium in the plume of a single burning coal particle  

Science Conference Proceedings (OSTI)

The release of volatile sodium during coal combustion is a significant factor in the fouling and corrosion of heat transfer surfaces within industrial coal-fired boilers. A method for measuring the temporal release of atomic sodium from a single coal particle is described. Laser absorption was used to calibrate laser-induced fluorescence measurements of atomic sodium utilising the sodium D1 line (589.59 nm) in a purpose-designed flat flame environment. The calibration was then applied to planar laser-induced fluorescence measurements of sodium atoms in the plume from a single Victorian brown coal particle (53 mg) suspended within the flat flame. The peak concentration of atomic sodium was approximately 64.1 ppb after 1080.5 s, which appears to correspond to the end of char combustion. To our knowledge this is the first in situ quantitative measurement of the concentration field of atomic sodium in the plume above a burning particle. A simple kinetic model has been used to estimate the rate of sodium decay in the post-flame gases. Comparison of the estimated and measured decay rates showed reasonable agreement. (author)

Dig-face monitoring during excavation of a radioactive plume at Mound Laboratory, Ohio  

Science Conference Proceedings (OSTI)

A dig-face monitoring system consists of onsite hardware for collecting information on changing chemical, radiological, and physical conditions in the subsurface soil during the hazardous site excavation. A prototype dig-face system was take to Mount Laboratory for a first trial. Mound Area 7 was the site of historical disposals of {sup 232}Th, {sup 227}Ac, and assorted debris. The system was used to monitor a deep excavation aimed at removing {sup 227}Ac-contaminated soils. Radiological, geophysical, and topographic sensors were used to scan across the excavation dig-face at four successive depths as soil was removed. A 3-D image of the contamination plumes was developed; the radiation sensor data indicated that only a small portion of the excavated soil volume was contaminated. The spatial information produced by the dig-face system was used to direct the excavation activities into the area containing the {sup 227}Ac and to evaluate options for handling the separate {sup 232}Th plume.

Dynamics of femto- and nanosecond laser ablation plumes investigated using optical emission spectroscopy  

Science Conference Proceedings (OSTI)

We investigated the spatial and temporal evolution of temperature and electron density associated with femto- and nanosecond laser-produced plasmas (LPP) from brass under similar laser fluence conditions. For producing plasmas, brass targets were ablated in vacuum employing pulses either from a Ti:Sapphire ultrafast laser (40 fs, 800 nm) or from a Nd:YAG laser (6 ns, 1064 nm). Optical emission spectroscopy is used to infer the density and temperature of the plasmas. The electron density (n{sub e}) was estimated using Stark broadened profiles of isolated lines while the excitation temperature (T{sub exc}) was estimated using the Boltzmann plot method. At similar fluence levels, continuum and ion emission are dominant in ns LPP at early times (<50 ns) followed by atomic emission, while the fs LPP provided an atomic plume throughout its visible emission lifetime. Though both ns and fs laser-plasmas showed similar temperatures ({approx}1 eV), the fs LPP is found to be significantly denser at shorter distances from the target surface as well as at early phases of its evolution compared to ns LPP. Moreover, the spatial extension of the plume emission in the visible region along the target normal is larger for fs LPP in comparison with ns LPP.

Abandoned Texas oil fields  

SciTech Connect

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

Shale oil cracking. 1. Kinetics  

DOE Green Energy (OSTI)

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

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

That's up nearly 700,000 barrels per day from last year and the highest annual oil output since 1997 says the U.S. Energy Information Administration in its new monthly short-term energy outlook for September. EIA analyst Sam Gorgen explains: "Higher oil supplies, especially from North Dakota and Texas, boosted U.S. oil production. The number of on-shore drilling rigs targeting oil nationwide has increased by around 200 so far this year to just under 1,400 rigs." Higher domestic oil production will help cut U.S. petroleum imports. The share of total U.S.

Regional Residential Heating Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

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

Business cycles in oil economies  

SciTech Connect

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

Market assessment for shale oil  

SciTech Connect

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

Mercury emissions from a simulated in-situ oil shale retort  

DOE Green Energy (OSTI)

In simulated in-situ retorting, lesser amounts of mercury are distributed to the spent shale, shale oil, and water than to the offgas. The mercury release is controlled by the successive volatilization and removal of mercury as the reaction front progresses down the shale bed. Oil-wet shale, enriched in heavy ends, may selectively remove the mercury from the gaseous phase. If nonuniform gas flow occurs in commercial retorts, mercury may be condensed in cool regions of the shale bed behind the reaction front where it may be subsequently leached by groundwaters. In a 50,000 bpd or larger commercial operation, it is likely that mercury will have to be removed from the gas stream to meet air quality standards or emission standards. Existing control technologies under consideration for oil shale plants need to be evaluated to determine their mercury removal efficiency. Mercury levels in retort waters would exceed water quality standards and criteria for discharge to local streams and mercury would have to be removed from these waters before discharge. Additional work is required to determine the fate and form of the mercury in a stack plume and the effect of the oil-wet zone on the removal of mercury from the gas phase. 5 figures, 9 tables.

Oil shale: Technology status report  

Science Conference Proceedings (OSTI)

This report documents the status of the US Department of Energy's (DOE) Oil Shale Program as of the end of FY 86. The report consists of (1) a status of oil shale development, (2) a description of the DOE Oil Shale Program, (3) an FY 86 oil shale research summary, and (4) a summary of FY 86 accomplishments. Discoveries were made in FY 86 about the physical and chemical properties and behavior of oil shales, process chemistry and kinetics, in situ retorting, advanced processes, and the environmental behavior and fate of wastes. The DOE Oil Shale Program shows an increasing emphasis on eastern US oil shales and in the development of advanced oil shale processing concepts. With the award to Foster Wheeler for the design of oil shale conceptual plants, the first step in the development of a systems analysis capability for the complete oil shale process has been taken. Unocal's Parachute Creek project, the only commercial oil shale plant operating in the United States, is operating at about 4000 bbl/day. The shale oil is upgraded at Parachute Creek for input to a conventional refinery. 67 refs., 21 figs., 3 tabs.

SCFA lead lab technical assistance at Lawrence Berkeley National Laboratory: Baseline review of three groundwater plumes  

SciTech Connect

During the closeout session, members of the technical assistance team conveyed to the site how impressed they were at the thoroughness of the site's investigation and attempts at remediation. Team members were uniformly pleased at the skilled detection work to identify sources, make quick remediation decisions, and change course when a strategy did not work well. The technical assistance team also noted that, to their knowledge, this is the only DOE site at which a world-class scientist has had primary responsibility for the environmental restoration activities. This has undoubtedly contributed to the successes observed and DOE should take careful note. The following overall recommendations were agreed upon: (1) The site has done a phenomenal job of characterization and identifying and removing source terms. (2) Technologies selected to date are appropriate and high impact, e.g. collection trenches are an effective remedial strategy for this complicated geology. The site should continue using technology that is adapted to the site's unique geology, such as the collection trenches. (3) The site should develop a better way to determine the basis of cleanup for all sites. (4) The sentinel well system should be evaluated and modified, if needed, to assure that the sentinel wells provide coverage to the current site boundary. Potential modifications could include installation, abandonment or relocation of wells based on the large amount of data collected since the original sentinel well system was designed. (5) Modeling to assist in remedial design and communication should continue. (6) The site should develop a plan to ensure institutional memory. (7) The most likely possibility for improving closure to 2006 is by removing the residual source of the Old Town plume and establishing the efficacy of remediation for the 51/64 plume.

Measuring Dependence on Imported Oil  

Gasoline and Diesel Fuel Update (EIA)

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

Unconventional Oil and Gas Resources  

Science Conference Proceedings (OSTI)

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

Oil shale retort apparatus  

DOE Patents (OSTI)

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

Oil Prices and Inflation  

E-Print Network (OSTI)

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

Production of Shale Oil  

E-Print Network (OSTI)

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

"Future of oil supplies"  

E-Print Network (OSTI)

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

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

Consumer Winter Heating Oil Costs  

Gasoline and Diesel Fuel Update (EIA)

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

Retail Diesel Fuel Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

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

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

E-Print Network (OSTI)

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

Oil cooled, hermetic refrigerant compressor  

DOE Patents (OSTI)

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