  6. Testing of the Pleasant Bayou Well through October 1990

    SciTech Connect (OSTI)

    Randolph, P.L.; Hayden, C.G.; Mosca, V.L.; Anhaiser, J.L.


    Pleasant Bayou location was inactive from 1983 until the cleanout of the production and disposal wells in 1986. The surface facilities were rehabilitated and after shakedown of the system, additional repair of wellhead valves, and injection of an inhibitor pill, continuous long-term production was started in 1988. Over two years of production subsequent to that are reviewed here, including: production data, brine sampling and analysis, hydrocarbon sampling and analysis, solids sampling and analysis, scale control and corrosion monitoring and control.

  7. Compaction measurements on cores from the Pleasant Bayou wells

    SciTech Connect (OSTI)

    Jogi, P.N.; Gray, K.E.; Ashman, T.R.; Thompson, T.W.; Bebout, D.G.; Bachman, A.L.


    Additional measurements of compressibility, compaction coefficients, porosities, permeabilities, and resistivities have been conducted on cores from Pleasant Bayou wells No. 1 and No. 2. All rock parameters show non-linear behavior with changing reservoir or pore pressure, which is of interest in modelling reservoir performance and subsidence. Compressibilities and uniaxial compaction coefficients decline by a factor of 2 to 3 as reservoir pressure declines from geopressured to normal hydrostatic conditions. Porosity reductions are 6 to 8% while permeability reductions are on the order of 10 to 30% over that reservoir pressure range. Measured formation factors were 2 to 4 times log derived values for F. Matrix compressibilities were not insignificant relative to bulk compressibilities.

  9. An integrated approach to reservoir engineering at Pleasant Bayou Geopressured-Geothermal reservoir

    SciTech Connect (OSTI)

    Shook, G.M.


    A numerical model has been developed for the Pleasant Bayou Geothermal-Geopressured reservoir. This reservoir description is the result of integration of a variety of data, including geological and geophysical interpretations, pressure transient test analyses, and well operations. Transient test analyses suggested several enhancements to the geologic description provided by University of Texas Bureau of Economic Geology (BEG), including the presence of an internal fault not previously identified. The transient tests also suggested water influx from an adjacent aquifer during the long-term testing of Pleasant Bayou; comparisons between transient test analyses and the reservoir description from BEG suggests that this fault exhibits pressure-dependent behavior. Below some pressure difference across the fault, it remains a no-flow barrier; above this threshold pressure drop the barrier fails, and fluid moves across the fault. A history match exercise is presented, using the hypothesized {open_quotes}leaky fault.{close_quotes} Successful match of 4 years of production rates and estimates of average reservoir pressure supports the reservoir description developed herein. Sensitivity studies indicate that the degree of communication between the perforated interval and the upper and lower sands in the reservoir (termed {open_quotes}distal volume{close_quotes} by BEG) impact simulation results very little, whereas results are quite sensitive to storage and transport properties of this distal volume. The prediction phase of the study indicates that Pleasant Bayou is capable of producing 20,000 STB/d through 1997, with the final bottomhole pressure approximately 1600 psi above abandonment pressure.

    SciTech Connect (OSTI)

    Teggers, H.; Theis, K.A.; Tonnesmann, A.; Fabianek, G.


    In 1981, the Rheinische Braunkohlenwerke AG (Rheinbraun) started constructing the first commercial-scale plant applying the High-Temperature Winkler (HTW) Process in the Federal Republic of Germany, at the site of Rheinbraun's Ville plant (Hurth-Berrenrath). This demonstration plant represents the consequent continuation of the company's R and D efforts regarding development and testing of new lignite gasification and liquefaction processes up to industrial-scale operational maturity. Rhenish lignite is particularly suited for conversion purposes due to its favourable mining conditions and high reactivity. In addition to further developing the Winkler process, up to the so-called High-Temperature Winkler (HTW) process for the production of synthesis gases rich in CO and H/sub 2/, a second gassification process based on the fluidized-bed principle, the lignite hydrogasification process (HUV) for the production of SNG is being developed. Operational result of a small-scale test plant are presented and the HTW process of SNG production for methanol production is described.

    Sisterson, D.L.


    This month the authors will visit an ARM CART site with a pleasant climate: the Tropical Western Pacific (TWP) CART site, along the equator in the western Pacific Ocean. The TWP locale lies between 10 degrees North latitude and 10 degrees South latitude and extends from Indonesia east-ward beyond the international date line. This area was selected because it is in and around the Pacific warm pool, the area of warm sea-surface temperatures that determine El Nino/La Nina episodes. The warm pool also adds heat and moisture to the atmosphere and thus fuels cloud formation. Understanding the way tropical clouds and water vapor affect the solar radiation budget is a focus of the ARM Program. The two current island-based CART sites in the TWP are in Manus Province in Papua New Guinea and on Nauru Island.

    One of the pleasant bits of news that sprouted in many places across the country last fall concerned the increased LP-gas gallonage for crop drying. It is difficult to predict the farmers or dryers' consumption of propane in any given season. The demand for this fuel in drying operations is determined almost entirely by weather conditions, and since climate remains a perennial question mark, no one knows until the season is well under way how much moisture content the plants will exhibit. In another area, predictions can be complicated by the variations of individual farm practices as well as the evolving technology of drying equipment, including burners. This article, reports on the crop drying market as seen by various LP-gas dealers and others outside the industry.

    This project was awarded under U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) Program Solicitation DE-PS26-02NT41422 and specifically addresses Program Area of Interest: No.5--Environmental and Water Resources. The project team includes the Electric Power Research Institute (EPRI) as the contractor and the University of North Dakota Energy & Environmental Research Center (EERC) and Frontier Geosciences as subcontractors. Wisconsin Energies and its Pleasant Prairie Power Plant acted as host for the field-testing portion of the research. The project is aimed at clarifying the role, rates, and end results of chemical transformations that may occur to mercury that has been emitted from elevated stacks of coal-fired electric power plants. Mercury emitted from power plants emerges in either its elemental, divalent, or particulate-bound form. Deposition of the divalent form is more likely to occur closer to the source than that of the other two forms, due to its solubility in water. Thus, if chemical transformations occur in the stack emissions plume, measurements in the stack may mischaracterize the fate of the material. Initial field and pilot plant measurements have shown significant and rapid chemical reduction of divalent to elemental mercury may occur in these plumes. Mercury models currently assume that the chemical form of mercury occurring in stacks is the same as that which enters the free atmosphere, with no alteration occurring in the emissions plume. Recent data indicate otherwise, but need to be evaluated at full operating scale under field conditions. Prestbo and others have demonstrated the likelihood of significant mercury chemical reactions occurring in power plant plumes (Prestbo et al., 1999; MDNR-PPRP, 2000; EERC, 2001). This experiment will thus increase our understanding of mercury atmospheric chemistry, allowing informed decisions regarding source attribution. The experiment was carried out during the period August 22

  2. Direct Measurement of Mercury Reactions In Coal Power Plant Plumes

    SciTech Connect (OSTI)

    Leonard Levin


    Recent field and pilot-scale results indicate that divalent mercury emitted from power plants may rapidly transform to elemental mercury within the power plant plumes. Simulations of mercury chemistry in plumes based on measured rates to date have improved regional model fits to Mercury Deposition Network wet deposition data for particular years, while not degrading model verification fits for remaining years of the ensemble. The years with improved fit are those with simulated deposition in grid cells in the State of Pennsylvania that have matching MDN station data significantly less than the model values. This project seeks to establish a full-scale data basis for whether or not significant reduction or oxidation reactions occur to mercury emitted from coal-fired power plants, and what numerical redox rate should apply for extension to other sources and for modeling of power plant mercury plumes locally, regionally, and nationally. Although in-stack mercury (Hg) speciation measurements are essential to the development of control technologies and to provide data for input into atmospheric fate and transport models, the determination of speciation in a cooling coal combustion plume is more relevant for use in estimating Hg fate and effects through the atmosphere. It is mercury transformations that may occur in the plume that determine the eventual rate and patterns of mercury deposited to the earth's surface. A necessary first step in developing a supportable approach to modeling any such transformations is to directly measure the forms and concentrations of mercury from the stack exit downwind to full dispersion in the atmosphere. As a result, a study was sponsored by EPRI and jointly funded by EPRI, the U.S Department of Energy (DOE), and the Wisconsin Department of Administration. The study was designed to further our understanding of plume chemistry. The study was carried out at the We Energies Pleasant Prairie Power Plant, Pleasant Prairie, Wisconsin, just

    Rollins Environmental Services operates a Transfer and Storage facility at their Allworth site in Mt. Pleasant, Tennessee. VOC control was originally accomplished by the use of close capture vents routed through a Regenerative Thermal Oxidizer. Capture efficiencies at several locations in the plant where hazardous waste was sampled and processed had been inadequate to fully meet EPA Clean Air Act Amendments Best Available Control Technology (BACT) or the requirements of OSHA 1910 Subpart Z--Toxic and Hazardous Substances standards and OSHA 1910.120(p)(5)--New Technology Program without the use of high levels of personal protective equipment (PPE) and extensive Industrial Hygiene monitoring. Therefore, a program was instituted to install permanent total enclosures in these areas with the goal of 100% capture of VOC`s. This paper presents the methodology by which this program was conceived and managed and the findings of the Industrial Safety and Health monitoring studies performed before and after the installation of the Permanent Total Enclosures and balancing of air flows in the system.

    Having approached 0.5 m during the May 2 earthquake, the uplift of Quaternary deposits on the Coalinga anticline may provide evidence of the average repeat time of similar earthquakes during the recent geologic past. Stein and King (1984) estimated the average late Quaternary repeat time to be 500 to 1,500 yr from the degree of folding in the upper Pliocene and Pleistocene Tulare Formation; in addition, they estimated the average Holocene repeat time to be at least 200 to 600 yr on the basis of an alluvial-plain profile near Los Gatos Creek, whose arroyo extends across the Coalinga anticline from the synclinal Pleasant Valley into the synclinal San Joaquin Valley. In this chapter, the authors estimate an average repeat time from the stratigraphy of Holocene alluvium exposed in the walls of that arroyo. Largely deposited overbank, this alluvium reveals the approximate configuration of former alluvial plains whose present configuration over the anticline should reflect the rate of anticlinal growth. Resulting constraints on the Holocene uplift rate, though made uncertain by possible differences in the initial configuration of the alluvial plains, suggest an average repeat time of at least 200 to 1,000 yr for major (M = 6-7) Coalinga-area earthquakes during the late Holocene.

    Ten Kanas oil reservoirs/leases were studied through geological and engineering analysis to assess the potential performance of chemical flooding to recover oil. Reservoirs/leases that have been efficiently waterflooded have the highest performance potential for chemical flooding. Laboratory work to identify efficient chemical systems and to test the oil recovery performance of the systems was the major effort of the project. Efficient chemical systems were identified for crude oils from nine of the reservoirs/leases. Oil recovery performance of the identified chemical systems in Berea sandstone rocks showed 90+ % recoveries of waterflood residual oil for seven crude oils. Oil recoveries increased with the amount of chemical injected. Recoveries were less in Indiana limestone cores. One formulation recovered 80% of the tertiary oil in the limestone rock. Geological studies for nine of the oil reservoirs are presented. Pleasant Prairie, Trembley, Vinland and Stewart Oilfields in Kansas were the most favorable of the studied reservoirs for a pilot chemical flood from geological considerations. Computer simulations of the performance of a laboratory coreflood were used to predict a field application of chemical flooding for the Trembley Oilfield. Estimates of field applications indicated chemical flooding is an economically viable technology for oil recovery.

    The 2010 Gordon Research Conference on Microbial Stress Responses provides an open and exciting forum for the exchange of scientific discoveries on the remarkable mechanisms used by microbes to survive in nearly every niche on the planet. Understanding these stress responses is critical for our ability to control microbial survival, whether in the context of biotechnology, ecology, or pathogenesis. From its inception in 1994, this conference has traditionally employed a very broad definition of stress in microbial systems. Sessions will cover the major steps of stress responses from signal sensing to transcriptional regulation to the effectors that mediate responses. A wide range of stresses will be represented. Some examples include (but are not limited to) oxidative stress, protein quality control, antibiotic-induced stress and survival, envelope stress, DNA damage, and nutritional stress. The 2010 meeting will also focus on the role of stress responses in microbial communities, applied and environmental microbiology, and microbial development. This conference brings together researchers from both the biological and physical sciences investigating stress responses in medically- and environmentally relevant microbes, as well as model organisms, using cutting-edge techniques. Computational, systems-level, and biophysical approaches to exploring stress responsive circuits will be integrated throughout the sessions alongside the more traditional molecular, physiological, and genetic approaches. The broad range of excellent speakers and topics, together with the intimate and pleasant setting at Mount Holyoke College, provide a fertile ground for the exchange of new ideas and approaches.

    Xgrid, with a capital-X is the name for Apple's grid computing system. With a lower case x, xgrid is the name of the command line utility that clients can use, among other ways, to submit jobs to a controller. An Xgrid divides into three logical components: Agent, Controller and Client. Client computers submit jobs (a set of tasks) they want run to a Controller computer. The Controller queues the Client jobs and distributes tasks to Agent computers. Agent computers run the tasks and report their output and status back to the controller where it is stored until deleted by the Client. The Clients can asynchronously query the controller about the status of a job and the results. Any OSX computer can be any of these. A single mac can be more than one: it's possible to be Agent, Controller and Client at the same time. There is one Controller per Grid. Clients can submit jobs to Controllers of different grids. Agents can work for more than one grid. Xgrid's setup has a pleasantly small palette of choices. The first two decisions to make are the kind of authentication & authorization to use and if a shared file system is needed. A shared file system that all the agents can access can be very beneficial for many computing problems, but it is not appropriate for every network.

    This report, prepared by a US Department of Energy (DOE) Task Force and organized for clarity into two-page modules, argues that the US Department of Transportation (DOT) Specification-6M packagings (hereafter referred to as 6M packaging, or simply 6M) merit continued DOE use and, if necessary, DOE certification. This report is designed to address the specific requirements of a Safety Analysis Report for Packaging (SARP). While not a SARP, this report constitutes a compilation of all available documentation on 6M packagings. The authors individually, and the Task Force collectively, believe their investigation provides justification for the continued use of 6M packagings because they meet criteria for quality assurance and for safety under normal and accident conditions as defined by the US Nuclear Regulatory Commission (NRC) regulations. This report may be used by DOE managers to assist in deliberations on future requirements for 6M packagings as they are required to support DOE programs. For the purpose of ready evaluation, this report includes categorical topics found in Nuclear Regulatory Guide 7.9, the topical guideline for SARPs. The format, however, will (it is hoped) pleasantly surprise customary reader expectations. For, while maintaining categorical headings and subheadings found in SARPs as a skeleton, the Task Force chose to adopt the document design principles developed by Hughes Aircraft in the 1960s, ''Sequential Thematic Organization of Publications'' (STOP). 37 figs.

    Large scale transportation projects can adversely affect the visual perception of environmental quality and require adequate visual impact assessment. In this study, we investigated the effects of the characteristics of the road project and the character of the existing landscape on the perceived visual impact of motorways, and developed a GIS-based prediction model based on the findings. An online survey using computer-visualised scenes of different motorway and landscape scenarios was carried out to obtain perception-based judgements on the visual impact. Motorway scenarios simulated included the baseline scenario without road, original motorway, motorways with timber noise barriers, transparent noise barriers and tree screen; different landscape scenarios were created by changing land cover of buildings and trees in three distance zones. The landscape content of each scene was measured in GIS. The result shows that presence of a motorway especially with the timber barrier significantly decreases the visual quality of the view. The resulted visual impact tends to be lower where it is less visually pleasant with more buildings in the view, and can be slightly reduced by the visual absorption effect of the scattered trees between the motorway and the viewpoint. Based on the survey result, eleven predictors were identified for the visual impact prediction model which was applied in GIS to generate maps of visual impact of motorways in different scenarios. The proposed prediction model can be used to achieve efficient and reliable assessment of visual impact of motorways. - Highlights: • Motorways induce significant visual impact especially with timber noise barriers. • Visual impact is negatively correlated with amount of buildings in the view. • Visual impact is positively correlated with percentage of trees in the view. • Perception-based motorway visual impact prediction model using mapped predictors • Predicted visual impacts in different scenarios are

    The detection of seven fast radio bursts (FRBs) has recently been reported. FRBs are short duration (?1 ms), highly dispersed radio pulses from astronomical sources. The physical interpretation for the FRBs remains unclear but is thought to involve highly compact objects at cosmological distance. It has been suggested that a fraction of FRBs could be physically associated with gamma-ray bursts (GRBs). Recent radio observations of GRBs have reported the detection of two highly dispersed short duration radio pulses using a 12 m radio telescope at 1.4 GHz. Motivated by this result, we have performed a systematic and sensitive search for FRBs associated with GRBs. We have observed five GRBs at 2.3 GHz using a 26 m radio telescope located at the Mount Pleasant Radio Observatory, Hobart. The radio telescope was automated to rapidly respond to Gamma-ray Coordination Network notifications from the Swift satellite and slew to the GRB position within ?140 s. The data were searched for pulses up to 5000 pc cm{sup 3} in dispersion measure and pulse widths ranging from 640 ?s to 25.60 ms. We did not detect any events ?6?. An in depth statistical analysis of our data shows that events detected above 5? are consistent with thermal noise fluctuations only. A joint analysis of our data with previous experiments shows that previously claimed detections of FRBs from GRBs are unlikely to be astrophysical. Our results are in line with the lack of consistency noted between the recently presented FRB event rates and GRB event rates.

    The dedication of the new Environmental Sciences Laboratory coincided with the 25th year of the establishment of the science of ecology at Oak Ridge National Laboratory. That quarter century witnessed the evolution of ecology from an obscure, backwater discipline of biology to a broadly used, everyday household word. The transition reflected broad and basic changes in our social and cultural view of the world. This was brought about as a result of the awareness developed in our society of the importance of the environment, coupled with efforts of ecologists and other environmental scientists who identified, clarified, and formulated the issues and challenges of environmental protection for both the lay public and the scientific community. In many respects, the activities in ecology at ORNL were a microcosm of the broader social scene; the particular problems of the environment associated with atomic energy needed to be defined in scientific terms and articulated in both the specific and general sense for a larger audience which was unfamiliar with the field and somewhat alien to its concepts and philosophy. The success of this effort is reflected in the existence of the new Environmental Sciences Laboratory. This dedication volume brings together the thoughts and reflections of many of these scientists whose efforts contributed in a unique and individualistic fashion not only to ORNL but also to the national identification of ecology and its importance to the achievement of our national goals. Their remarks and presentations are not only a pleasant and personally gratifying recapitulation of the past and of ORNL's contributions to ecology but also portend some of the challenges to ecology in the future.

    Mercury (Hg) control technologies were evaluated at Minnkota Power Cooperative's Milton R. Young (MRY) Station Unit 2, a 450-MW lignite-fired cyclone unit near Center, North Dakota, and TXU Energy's Monticello Steam Electric Station (MoSES) Unit 3, a 793-MW lignite--Powder River Basin (PRB) subbituminous coal-fired unit near Mt. Pleasant, Texas. A cold-side electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) scrubber are used at MRY and MoSES for controlling particulate and sulfur dioxide (SO{sub 2}) emissions, respectively. Several approaches for significantly and cost-effectively oxidizing elemental mercury (Hg{sup 0}) in lignite combustion flue gases, followed by capture in an ESP and/or FGD scrubber were evaluated. The project team involved in performing the technical aspects of the project included Babcock & Wilcox, the Energy & Environmental Research Center (EERC), the Electric Power Research Institute, and URS Corporation. Calcium bromide (CaBr{sub 2}), calcium chloride (CaCl{sub 2}), magnesium chloride (MgCl{sub 2}), and a proprietary sorbent enhancement additive (SEA), hereafter referred to as SEA2, were added to the lignite feeds to enhance Hg capture in the ESP and/or wet FGD. In addition, powdered activated carbon (PAC) was injected upstream of the ESP at MRY Unit 2. The work involved establishing Hg concentrations and removal rates across existing ESP and FGD units, determining costs associated with a given Hg removal efficiency, quantifying the balance-of-plant impacts of the control technologies, and facilitating technology commercialization. The primary project goal was to achieve ESP-FGD Hg removal efficiencies of {ge}55% at MRY and MoSES for about a month.

    The purpose of this work consists in thermodynamic modeling of hybrid photovoltaic-thermal (PV/T) solar systems, pursuing a modular strategy approach provided by Simulink/Matlab. PV/T solar systems are a recently emerging solar technology that allows for the simultaneous conversion of solar energy into both electricity and heat. This type of technology present some interesting advantages over the conventional ''side-by-side'' thermal and PV solar systems, such as higher combined electrical/thermal energy outputs per unit area, and a more uniform and aesthetical pleasant roof area. Despite the fact that early research on PV/T systems can be traced back to the seventies, only recently it has gained a renewed impetus. In this work, parametric studies and annual transient simulations of PV/T systems are undertaken in Simulink/Matlab. The obtained results show an average annual solar fraction of 67%, and a global overall efficiency of 24% (i.e. 15% thermal and 9% electrical), for a typical four-person single-family residence in Lisbon, with p-Si cells, and a collector area of 6 m{sup 2}. A sensitivity analysis performed on the PV/T collector suggests that the most important variable that should be addressed to improve thermal performance is the photovoltaic (PV) module emittance. Based on those results, some additional improvements are proposed, such as the use of vacuum, or a noble gas at low-pressure, to allow for the removal of PV cells encapsulation without air oxidation and degradation, and thus reducing the PV module emittance. Preliminary results show that this option allows for an 8% increase on optical thermal efficiency, and a substantial reduction of thermal losses, suggesting the possibility of working at higher fluid temperatures. The higher working temperatures negative effect in electrical efficiency was negligible, due to compensation by improved optical properties. The simulation results are compared with experimental data obtained from other authors

    About 30 electric utility units with a combined total of 15,000 MW utilize magnesium enhanced lime flue gas desulfurization (FGD) systems. A disadvantage of this and other inhibited or natural oxidation wet FGD systems is the capital and operating cost associated with landfill disposal of the calcium sulfite based solids. Fixation to stabilize the solids for compaction in a landfill also consumes fly ash that otherwise may be marketable. This Executive Summary describes efforts to dewater the magnesium hydroxide and gypsum slurries and then process the solids into a more user friendly and higher value form. To eliminate the cost of solids disposal in its first generation Thiosorbic® system, the Dravo Lime Company developed the ThioClear® process that utilizes a magnesium based absorber liquor to remove S02 with minimal suspended solids. Magnesium enhanced lime is added to an oxidized bleed stream of thickener overflow (TOF) to produce magnesium hydroxide [Mg(OH)2] and gypsum (CaS04 • 2H20), as by-products. This process was demonstrated at the 3 to 5 MW closed loop FGD system pilot plant at the Miami Fort Station of Cinergy, near Cincinnati, Ohio with the help of OCDO Grant Agreement CDO/D-91-6. A similar process strictly for'recovery and reuse of Mg(OH)2 began operation at the Zimmer Station of Cinergy in late 1994 that can produce 900 pounds of Mg(OH)2 per hour and 2,600 pounds of gypsum per hour. This by-product plant, called the Zimmer Slipstream Magnesium Hydroxide Recovery Project Demonstration, was conducted with the help of OCDO Grant Agreement CDO/D-921-004. Full scale ThioClear® plants began operating in 1997 at the 130 MW Applied Energy Services plant, in Monaca, PA, and in year 2000 at the 1,330 MW Allegheny Energy Pleasants Station at St. Marys, WV.

    Canavan, Gregory H


    In the depths of the cold war there were few places where it was possible, let alone acceptable, to discuss global problems and their solution. Erice provided such a venue. Prof. Zichichi built it by inviting friends of international statue to visit Erice to discuss fundamental problems in science, technology, and society. Gradually the discussions were broadened to the more sensitive issues of global war and its consequences, which ranged from strategic forces and their stability to missile defenses and their impacts. Erice was one of the few places that these problems and their possible solutions could be discussed in a dispassionate and productive manner. Much of the reason these discussions remained objective and productive was Prof. Zichichi's 'gentle' prodding of participants towards a useful solution that all could accept. All was not deadly serious. I often accompanied Dr. Teller to the meetings, which he enjoyed enormously because they recalled the free-wheeling discussions he participated in when quantum physics was in its infancy. It was also pleasant to see him interact with Prof. Lee, who still gave Dr. Teller the deference due his old professor, and Dr. Garwin, who had worked with Dr. Teller in Los Alamos. By the end of the cold war Erice was recognized as a valuable site for such discussions. Perhaps for that reason, when the transfer of power in the Soviet Union evolved into an attempted coup, President Yeltsin sent a large contingent of scientists in his own plane to participate in the Erice seminar. It soon appeared that this contingent was not chosen randomly, but might contain many of the scientists who knew their missile launch codes. Despite their senior status, they quickly proved themselves to be competent scientists and enthusiastic participants. A by product to that interaction developed the following year when the Russian economy faltered and its science needed external support lest nuclear scientists leave Russia. U.S. scientific

    Godec, Michael


    Building upon advances in technology, production of natural gas from organic-rich shales is rapidly developing as a major hydrocarbon supply option in North America and around the world. The same technology advances that have facilitated this revolution - dense well spacing, horizontal drilling, and hydraulic fracturing - may help to facilitate enhanced gas recovery (EGR) and carbon dioxide (CO{sub 2}) storage in these formations. The potential storage of CO {sub 2} in shales is attracting increasing interest, especially in Appalachian Basin states that have extensive shale deposits, but limited CO{sub 2} storage capacity in conventional reservoirs. The goal of this cooperative research project was to build upon previous and on-going work to assess key factors that could influence effective EGR, CO{sub 2} storage capacity, and injectivity in selected Eastern gas shales, including the Devonian Marcellus Shale, the Devonian Ohio Shale, the Ordovician Utica and Point Pleasant shale and equivalent formations, and the late Devonian-age Antrim Shale. The project had the following objectives: (1) Analyze and synthesize geologic information and reservoir data through collaboration with selected State geological surveys, universities, and oil and gas operators; (2) improve reservoir models to perform reservoir simulations to better understand the shale characteristics that impact EGR, storage capacity and CO{sub 2} injectivity in the targeted shales; (3) Analyze results of a targeted, highly monitored, small-scale CO{sub 2} injection test and incorporate into ongoing characterization and simulation work; (4) Test and model a smart particle early warning concept that can potentially be used to inject water with uniquely labeled particles before the start of CO{sub 2} injection; (5) Identify and evaluate potential constraints to economic CO{sub 2} storage in gas shales, and propose development approaches that overcome these constraints; and (6) Complete new basin

  20. QER- Comment of Joy Kaubin

    Broader source: [DOE]

    Dear QER members, I am a resident of Lake Pleasant, MA, immediately adjacent to where the natural gas Pipeline is proposed to go through. Many residents here are opposed to the Pipeline and concerned with safety issues, property value issues, and ecological concerns (protecting our precious environment, our "common wealth," if you will). I am also deeply opposed to fracked gas in general, with it's massive waste of WATER (a resource becoming more and more critically depleted worldwide), destruction of natural environments, pollution of soil and water supply systems, etc. In terms of green alternatives, I'd like to quote Steve Kurkoski, of Warwick, MA, who for more than eight years has been an active member of the Warwick Buildings & Energy Committee and the North Quabbin Energy group and recently wrote an excellent piece in our local Greenfield Recorder newspaper. I believe, like Steve, that "When we talk about meeting our energy needs, the conversation should start with: "First, conservation; second, energy efficiency . . . third, renewables; and fourth, polluting technologies such as fossil fuels and nuclear should be used only as a last resort. If we do not implement this list in the above order we will leave a very different climate and a planet that is very difficult for our children [and future generations!] to live on." "[Steve] offered these recommendations: ?? Institute to a greater extent "peak load shaving" (often addressed by voluntary cut-backs during periods of high demand). ? ? Make it mandatory that all future buildings are Zero Net Energy or Zero Plus Energy (where a building generates as much as or more energy than it uses). ? ? Institute a more aggressive "time of use" electric and gas metering system (higher rates during times of high demand). ? ? Put a severe carbon tax on all polluting energy producers. ? ? When comparing fuels, measure CO2 equivalent emissions for the complete cycle of extraction, transportation, storage, burning and waste

    1. Drilled, cored, and logged three wells to the basement and collecting more than 2,700 ft of conventional core; obtained 20 mi2 of multicomponent 3D seismic imaging and merged and reprocessed more than 125 mi2 of existing 3D seismic data for use in modeling CO2- EOR oil recovery and CO2 storage in five oil fields in southern Kansas. 2. Determined the technical feasibility of injecting and sequestering CO2 in a set of four depleted oil reservoirs in the Cutter, Pleasant Prairie South, Eubank, and Shuck fields in southwest Kansas; of concurrently recovering oil from those fields; and of quantifying the volumes of CO2 sequestered and oil recovered during the process. 3. Formed a consortium of six oil operating companies, five of which own and operate the four fields. The consortium became part of the Southwest Kansas CO2-EOR Initiative for the purpose of sharing data, knowledge, and interest in understanding the potential for CO2-EOR in Kansas. 4. Built a regional well database covering 30,000 mi2 and containing stratigraphic tops from ~90,000 wells; correlated 30 major stratigraphic horizons; digitized key wells, including wireline logs and sample logs; and analyzed more than 3,000 drill stem tests to establish that fluid levels in deep aquifers below the Permian evaporites are not connected to the surface and therefore pressures are not hydrostatic. Connectivity with the surface aquifers is lacking because shale aquitards and impermeable evaporite layers consist of both halite and anhydrite. 5. Developed extensive web applications and an interactive mapping system that do the following: a. Facilitate access to a wide array of data obtained in the study, including core descriptions and analyses, sample logs, digital (LAS) well logs, seismic data, gravity and magnetics maps, structural and stratigraphic maps, inferred fault traces, earthquakes, Class I and II disposal wells, and
