Gas utilization technologies  

SciTech Connect

One of the constant challenges facing the research community is the identification of technology needs 5 to 15 years from now. A look back into history indicates that the forces driving natural gas research have changed from decade to decade. In the 1970s research was driven by concerns for adequate supply; in the 1980s research was aimed at creating new markets for natural gas. What then are the driving forces for the 1990s? Recent reports from the natural gas industry have helped define a new direction driven primarily by market demand for natural gas. A study prepared by the Interstate Natural Gas Association of America Foundation entitled ``Survey of Natural Research, Development, and Demonstration RD&D Priorities`` indicated that in the 1990s the highest research priority should be for natural gas utilization and that technology development efforts should not only address efficiency and cost, but environmental and regulatory issues as well. This study and others, such as the report by the American Gas Association (A.G.A.) entitled ``Strategic Vision for Natural Gas Through the Year 2000,`` clearly identify the market sectors driving today`s technology development needs. The biggest driver is the power generation market followed by the industrial, transportation, appliance, and gas cooling markets. This is best illustrated by the GRI 1994 Baseline Projection on market growth in various sectors between the year 1992 and 2010. This paper highlights some of the recent technology developments in each one of these sectors.

Gas Storage Technology Consortium  

Science Conference Proceedings (OSTI)

Gas storage is a critical element in the natural gas industry. Producers, transmission and distribution companies, marketers, and end users all benefit directly from the load balancing function of storage. The unbundling process has fundamentally changed the way storage is used and valued. As an unbundled service, the value of storage is being recovered at rates that reflect its value. Moreover, the marketplace has differentiated between various types of storage services, and has increasingly rewarded flexibility, safety, and reliability. The size of the natural gas market has increased and is projected to continue to increase towards 30 trillion cubic feet (TCF) over the next 10 to 15 years. Much of this increase is projected to come from electric generation, particularly peaking units. Gas storage, particularly the flexible services that are most suited to electric loads, is critical in meeting the needs of these new markets. In order to address the gas storage needs of the natural gas industry, an industry-driven consortium was created-the Gas Storage Technology Consortium (GSTC). The objective of the GSTC is to provide a means to accomplish industry-driven research and development designed to enhance operational flexibility and deliverability of the Nation's gas storage system, and provide a cost effective, safe, and reliable supply of natural gas to meet domestic demand. This report addresses the activities for the quarterly period of July 1, 2006 to September 30, 2006. Key activities during this time period include: {lg_bullet} Subaward contracts for all 2006 GSTC projects completed; {lg_bullet} Implement a formal project mentoring process by a mentor team; {lg_bullet} Upcoming Technology Transfer meetings: {sm_bullet} Finalize agenda for the American Gas Association Fall Underground Storage Committee/GSTC Technology Transfer Meeting in San Francisco, CA. on October 4, 2006; {sm_bullet} Identify projects and finalize agenda for the Fall GSTC Technology Transfer Meeting, Pittsburgh, PA on November 8, 2006; {lg_bullet} Draft and compile an electronic newsletter, the GSTC Insider; and {lg_bullet} New members update.

Gas Storage Technology Consortium  

Science Conference Proceedings (OSTI)

The EMS Energy Institute at The Pennsylvania State University (Penn State) has managed the Gas Storage Technology Consortium (GSTC) since its inception in 2003. The GSTC infrastructure provided a means to accomplish industry-driven research and development designed to enhance the operational flexibility and deliverability of the nation's gas storage system, and provide a cost-effective, safe, and reliable supply of natural gas to meet domestic demand. The GSTC received base funding from the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL) Oil & Natural Gas Supply Program. The GSTC base funds were highly leveraged with industry funding for individual projects. Since its inception, the GSTC has engaged 67 members. The GSTC membership base was diverse, coming from 19 states, the District of Columbia, and Canada. The membership was comprised of natural gas storage field operators, service companies, industry consultants, industry trade organizations, and academia. The GSTC organized and hosted a total of 18 meetings since 2003. Of these, 8 meetings were held to review, discuss, and select proposals submitted for funding consideration. The GSTC reviewed a total of 75 proposals and committed co-funding to support 31 industry-driven projects. The GSTC committed co-funding to 41.3% of the proposals that it received and reviewed. The 31 projects had a total project value of $6,203,071 of which the GSTC committed $3,205,978 in co-funding. The committed GSTC project funding represented an average program cost share of 51.7%. Project applicants provided an average program cost share of 48.3%. In addition to the GSTC co-funding, the consortium provided the domestic natural gas storage industry with a technology transfer and outreach infrastructure. The technology transfer and outreach were conducted by having project mentoring teams and a GSTC website, and by working closely with the Pipeline Research Council International (PRCI) to jointly host technology transfer meetings and occasional field excursions. A total of 15 technology transfer/strategic planning workshops were held.

Gas hydrates: Technology status report  

Science Conference Proceedings (OSTI)

In 1983, the US Department of Energy (DOE) assumed the responsibility for expanding the knowledge base and for developing methods to recover gas from hydrates. These are ice-like mixtures of gas and water where gas molecules are trapped within a framework of water molecules. This research is part of the Unconventional Gas Recovery (UGR) program, a multidisciplinary effort that focuses on developing the technology to produce natural gas from resources that have been classified as unconventional because of their unique geologies and production mechanisms. Current work on gas hydrates emphasizes geological studies; characterization of the resource; and generic research, including modeling of reservoir conditions, production concepts, and predictive strategies for stimulated wells. Complementing this work is research on in situ detection of hydrates and field tests to verify extraction methods. Thus, current research will provide a comprehensive technology base from which estimates of reserve potential can be made, and from which industry can develop recovery strategies. 7 refs., 3 figs., 6 tabs.

Options for Gas-to-Liquids Technology in Alaska  

Science Conference Proceedings (OSTI)

The purposes of this work was to assess the effect of applying new technology to the economics of a proposed natural gas-to-liquids (GTL) plant, to evaluate the potential of a slower-paced, staged deployment of GTL technology, and to evaluate the effect of GTL placement of economics. Five scenarios were economically evaluated and compared: a no-major-gas-sales scenario, a gas-pipeline/LNG scenario, a fast-paced GTL development scenario, a slow-paced GTL development scenario, and a scenario which places the GTL plant in lower Alaska, instead of on the North Slope. Evaluations were completed using an after-tax discounted cash flow analysis. Results indicate that the slow-paced GTL scenario is the only one with a rate of return greater than 10 percent. The slow-paced GTL development would allow cost saving on subsequent expansions. These assumed savings, along with the lowering of the transportation tariff, combine to distinquish this option for marketing the North Slope gas from the other scenarios. Critical variables that need further consideration include the GTL plant cost, the GTL product premium, and operating and maintenance costs.

Unconventional gas outlook: resources, economics, and technologies  

Science Conference Proceedings (OSTI)

The report explains the current and potential of the unconventional gas market including country profiles, major project case studies, and new technology research. It identifies the major players in the market and reports their current and forecasted projects, as well as current volume and anticipated output for specific projects. Contents are: Overview of unconventional gas; Global natural gas market; Drivers of unconventional gas sources; Forecast; Types of unconventional gas; Major producing regions Overall market trends; Production technology research; Economics of unconventional gas production; Barriers and challenges; Key regions: Australia, Canada, China, Russia, Ukraine, United Kingdom, United States; Major Projects; Industry Initiatives; Major players. Uneconomic or marginally economic resources such as tight (low permeability) sandstones, shale gas, and coalbed methane are considered unconventional. However, due to continued research and favorable gas prices, many previously uneconomic or marginally economic gas resources are now economically viable, and may not be considered unconventional by some companies. Unconventional gas resources are geologically distinct in that conventional gas resources are buoyancy-driven deposits, occurring as discrete accumulations in structural or stratigraphic traps, whereas unconventional gas resources are generally not buoyancy-driven deposits. The unconventional natural gas category (CAM, gas shales, tight sands, and landfill) is expected to continue at double-digit growth levels in the near term. Until 2008, demand for unconventional natural gas is likely to increase at an AAR corresponding to 10.7% from 2003, aided by prioritized research and development efforts. 1 app.

Natural gas pipeline technology overview.  

Science Conference Proceedings (OSTI)

The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by transmission companies. Compressor stations at required distances boost the pressure that is lost through friction as the gas moves through the steel pipes (EPA 2000). The natural gas system is generally described in terms of production, processing and purification, transmission and storage, and distribution (NaturalGas.org 2004b). Figure 1.1-2 shows a schematic of the system through transmission. This report focuses on the transmission pipeline, compressor stations, and city gates.

Natural Gas Research Natural Gas Research Natural gas offers tremendous opportunities for reducing the use of petroleum in transportation. Medium and heavy-duty fleets, which have significant potential to use natural gas, currently consume more than a third of the petroleum in transportation in the U.S. Natural gas is an excellent fit for a wide range of heavy-duty applications, especially transit buses, refuse haulers, and Class 8 long-haul or delivery trucks. In addition, natural gas can be a very good choice for light-duty vehicle fleets with central refueling. See the Alternative Fuels Data Center for a description of the uses and benefits of natural gas vehicles or its Laws and Incentives database for information on tax incentives. The Vehicle Technologies Office (VTO) supports the development of natural gas engines and research into renewable natural gas production.

Landfill gas recovery: a technology status report  

DOE Green Energy (OSTI)

Landfill gas, which consists mainly of methane and carbon dioxide, can be recovered and used as a fuel. Processing will upgrade it to a high-Btu gas of pipeline quality. There are more than a dozen commercial landfill-gas recovery facilities in the US at present, all at relatively large sites. The amount of gas produced by a given site is a function of size, composition, and age of the landfill. Various techniques can be used to enhance gas production and yield, including controlled addition of moisture and nutrients; bacterial seeding and pH control also appear useful. Several computer models have been developed to examine the effects of various parameters on gas production and yield; these can aid in predicting optimum gas recovery and in maintaining the proper chemical balance within the producing portion of the landfill. Economically, a site's viability depends on its location and potential users, current competing energy costs, and legislation governing the site's operation. Legal problems of site operation can occur because of environmental and safety issues, as well as from questions of gas ownership, liability, and public utility commission considerations. Currently, R and D is under way to improve present recovery techniques and to develop new technologies and concepts. Cost comparisons and potential environmental impacts are being examined. Additional research is needed in the areas of gas enhancement, decompositional analysis, computer modeling, gas characterization, instrumentation, and engineering cost analysis. 77 references, 11 figures, 23 tables.

Western gas sands: Technology status report  

Science Conference Proceedings (OSTI)

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

Physical gas stream cleanup: Technology status report  

SciTech Connect

This report is a summary of the status of particulate control technologies for use at high temperatures and high pressures. The technologies are being developed under the Physical Gas Stream Cleanup Program that is administered by the US Department of Energy, Morgantown Energy Technology Center. The intended uses of the particulate control technologies are to protect components in advanced coal systems, such as integrated gasification combined cycles, pressurized fluidized-bed combustion combined cycles, gasification molten carbonate fuel cells, and direct coal-fueled turbines. The use of particulate control technologies for these advanced energy conversion systems requires separation and collection of particles at temperatures in excess of 1000/sup 0/F and at pressures in excess of 7 atmospheres. These temperature and pressure regimes represent a drastic departure from those of conventional technologies. The Physical Gas Stream Cleanup Program seeks to establish a technical and economic data base that will demonstrate the feasibility of high-temperature, high-pressure particulate control. Particulate control concepts and their corresponding research and development projects are described in this report. These projects include subpilot-scale tests of an electrostatic precipitator, a ceramic cross-flow filter, and a screenless granular-bed filter on a 30-inch diameter pressurized fluidized-bed combustor. Bench-scale tests will also be conducted using a ceramic cross-flow filter, a ceramic bag filter, and an electrostatic precipitator on a 6-inch diameter fluidized-bed gasifier. Additional research involves laboratory evaluation of acoustic agglomeration, turbulence characterization and suppression in cyclones and characterization of ceramic fabrics for bag filters. Each project and significant accomplishments in FY 85 are described. 14 refs., 25 figs., 5 tabs.

A Search for non-Newtonian force in a precision measurement of the scattering of slow neutrons in Xenon gas  

E-Print Network (OSTI)

An experimental search for non-newtonian, gravity-like force in a precision measurement of the scattering of slow neutrons in Xenon gas is proposed. A preliminary experiment with small statistics of 25 hours irradiation time was performed and the observed scattering distribution is consistent with the expectation with no additional forces. A 95% CL limit on the coupling strength for a hypothetical force of 1 nm interaction range was evaluated to be 2*10^-15. The expected sensitivity for a planned high statistics runs is discussed.

Small gas-turbine-engine technology  

SciTech Connect

Performance of small gas turbine engines in the 250 to 1000 hp size range is significantly lower than that of large engines. Engines of this size are typically used in rotorcraft, commutercraft, general aviation, and cruise missile applications. Principal reasons for lower efficiencies of smaller engines are well known: Component efficiencies are lower by as much as 8 to 10 percentage points because of size effects. Small engines are designed for lower cycle pressures and temperatures because of smaller blading and cooling limitations. The highly developed analytical and manufacturing techniques evolved for large engines are not directly transferrable to small engines. Thus, it has been recognized that a focused effort addressing technologies for small engines was needed and could significantly impact their performance. Recently, in-house and contract studies were undertaken to identify advanced engine cycle and component requirements for substantial performance improvement of small gas turbines for projected year 2000 applications. This paper presents results of both in-house research and contract studies, conducted with Allison, AVCO Lycoming, Garrett, Teledyne CAE, and Williams International Rotorcraft results are emphasized. Projected fuel savings of 22-42% could be attained. Accompanying direct operating cost reductions of 11-17%, depending on fuel cost, were also estimated. High payoff technologies are identified for all engine applications, and recent results of experimental research to evolve the high payoff technologies are described.

Advanced Technologies For Stripper Gas Well Enhancement  

SciTech Connect

Stripper gas and oil well operators frequently face a dilemma regarding maximizing production from low-productivity wells. With thousands of stripper wells in the United States covering extensive acreage, it is difficult to identify easily and efficiently marginal or underperforming wells. In addition, the magnitude of reviewing vast amounts of data places a strain on an operator's work force and financial resources. Schlumberger DCS, in cooperation with the National Energy Technology Laboratory (NETL) and the U.S. Department of Energy (DOE), has created software and developed in-house analysis methods to identify remediation potential in stripper wells relatively easily. This software is referred to as Stripper Well Analysis Remediation Methodology (SWARM). SWARM was beta-tested with data pertaining to two gas fields located in northwestern Pennsylvania and had notable results. Great Lakes Energy Partners, LLC (Great Lakes) and Belden & Blake Corporation (B&B) both operate wells in the first field studied. They provided data for 729 wells, and we estimated that 41 wells were candidates for remediation. However, for reasons unbeknownst to Schlumberger these wells were not budgeted for rework by the operators. The second field (Cooperstown) is located in Crawford, Venango, and Warren counties, Pa and has more than 2,200 wells operated by Great Lakes. This paper discusses in depth the successful results of a candidate recognition study of this area. We compared each well's historical production with that of its offsets and identified 339 underperformers before considering remediation costs, and 168 economically viable candidates based on restimulation costs of $50,000 per well. From this data, we prioritized a list based on the expected incremental recoverable gas and 10% discounted net present value (NPV). For this study, we calculated the incremental gas by subtracting the volumes forecasted after remediation from the production projected at its current configuration. Assuming that remediation efforts increased production from the 168 marginal wells to the average of their respective offsets, approximately 6.4 Bscf of gross incremental gas with a NPV approximating $4.9 million after investment, would be made available to the domestic market. Seventeen wells have successfully been restimulated to date and have already obtained significant production increases. At the time of this report, eight of these wells had enough post-rework production data available to forecast the incremental gas and verify the project's success. This incremental gas is estimated at 615 MMscf. The outcome of the other ten wells will be determined after more post-refrac production data becomes available. Plans are currently underway for future restimulations. The success of this project has shown the value of this methodology to recognize underperforming wells quickly and efficiently in fields containing hundreds or thousands of wells. This contributes considerably to corporate net income and domestic natural gas and/or oil reserves.

The impacts of technology on global unconventional gas supply  

E-Print Network (OSTI)

As energy supplies from known resources are declining, the development of new energy sources is mandatory. One reasonable source is natural gas from unconventional resources. This study focus on three types of unconventional gas resources: coalbeds, tight sands, and shales. Whereas these resources are abundant, they have largely been overlooked and understudied, especially outside of North America. New technologies, including those needed to unlock unconventional gas (UCG) resources, have been acknowledged to be the most significant factor in increasing natural gas supply in the United States. This study evaluates advances in critical technology that will most likely increase supply the most. Advanced technology is one of the main drivers in increasing unconventional natural gas production, as observed in the United States, Canada, and Australia. 3D seismic, horizontal drilling, multilateral completion, water and gel based fracturing, coiled tubing rig, enhanced recovery, and produced water treatments are current important technologies critical in developing unconventional gas resources. More advanced technologies with significant impacts are expected to be available in the next decades. Fit-to-purpose technology reduces the cost to recover gas from unconventional resources. The better the unconventional gas resources are characterized, the better we can tailor specific technology to recover the gas, and less cost are needed. Analogy assumption is a good start in deciding which critical technology to be transferred to undeveloped unconventional reservoirs. If the key properties of two unconventional gas basins or formations are more or less similar, it is expected that the impact of certain technology applied in one basin or formation will resemble the impact to the other basin or formation.

NETL: News Release - DOE's Early Investment in Shale Gas Technology  

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

2, 2011 2, 2011 DOE's Early Investment in Shale Gas Technology Producing Results Today Washington, DC - A $92 million research investment in the 1970s by the U.S. Department of Energy (DOE) is today being credited with technological contributions that have stimulated development of domestic natural gas from shales. The result: more U.S. jobs, increased energy security, and higher revenues for states and the Federal Government. Spurred by the technological advancements resulting from this investment, U.S. shale gas production continues to grow, amounting to more than 8 billion cubic feet per day, or about 14 percent of the total volume of dry natural gas produced in the United States. DOE's Energy Information Administration (EIA) projects that the shale gas share of U.S. natural gas production will reach 45 percent by 2035. The EIA also projects that 827 trillion cubic feet of natural gas is now recoverable from U.S. shales using currently available technology-an increase of nearly 500 trillion cubic feet over earlier estimates.

Advanced natural gas fuel technologies for military installations. Final report  

SciTech Connect

Energy conservation efforts reduced Department of Defense (DoD) fossil fuel consumption considerably between FYX5 and FY9 I, yet electricity consumption increased. Electricity consumption accounts for only one-third of DoD energy use, but over half of DoD energy costs. In addition, the production of electricity at coal or nuclear plants often creates environmental concerns, while the use of clean-burning natural gas does not; its use can help DoD bases comply with increasingly stringent environmental regulations. Recent developments in natural gas-fired technologies also demonstrate improved efficiency and productivity at lower costs. This report identifies state-of-the-art and emerging natural gas utilization technologies with potential application on DoD installations. This report describes various technologies that have potential residential, commercial, or industrial applications on DoD installations. Applications include heating, cooling, power generation, food preparation, and several industrial processes.

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

Emerging Energy-Efficiency and Greenhouse Gas Mitigation Technologies for Emerging Energy-Efficiency and Greenhouse Gas Mitigation Technologies for the Pulp and Paper Industry Title Emerging Energy-Efficiency and Greenhouse Gas Mitigation Technologies for the Pulp and Paper Industry Publication Type Report Year of Publication 2012 Authors Kong, Lingbo, Ali Hasanbeigi, and Lynn K. Price Date Published 12/2012 Publisher Lawrence Berkeley National Laboratory Keywords emerging technologies, energy efficiency, ghg, Low Emission & Efficient Industry, pulp and paper Abstract The pulp and paper industry ranks fourth in terms of energy consumption among industries worldwide. Globally, the pulp and paper industry accounted for approximately 5 percent of total world industrial final energy consumption in 2007, and contributed 2 percent of direct carbon dioxide (CO2)emissions from industry. Worldwide pulp and paper demand and production are projected to increase significantly by 2050, leading to an increase in this industry's absolute energy use and greenhouse gas (GHG) emissions. Development of new energy-efficiency and GHG mitigation technologies and their deployment in the market will be crucial for the pulp and paper industry's mid- and long-term climate change mitigation strategies. This report describes the industry's processes and compiles available information on the energy savings, environmental and other benefits, costs, commercialization status, and references for 36 emerging technologies to reduce the industry's energy use and GHG emissions. Although studies from around the world identify a variety of sector-specific and cross-cutting energy-efficiency technologies that have already been commercialized for the pulp and paper industry, information is scarce and/or scattered regarding emerging or advanced energy-efficiency and low-carbon technologies that are not yet commercialized. The purpose of this report is to provide engineers, researchers, investors, paper companies, policy makers, and other interested parties with easy access to a well-structured resource of information on these technologies.

Evaluating the income and employment impacts of gas cooling technologies  

SciTech Connect

The purpose of this study is to estimate the potential employment and income benefits of the emerging market for gas cooling products. The emphasis here is on exports because that is the major opportunity for the U.S. heating, ventilating, and air-conditioning (HVAC) industry. But domestic markets are also important and considered here because without a significant domestic market, it is unlikely that the plant investments, jobs, and income associated with gas cooling exports would be retained within the United States. The prospects for significant gas cooling exports appear promising for a variety of reasons. There is an expanding need for cooling in the developing world, natural gas is widely available, electric infrastructures are over-stressed in many areas, and the cost of building new gas infrastructure is modest compared to the cost of new electric infrastructure. Global gas cooling competition is currently limited, with Japanese and U.S. companies, and their foreign business partners, the only product sources. U.S. manufacturers of HVAC products are well positioned to compete globally, and are already one of the faster growing goods-exporting sectors of the U.S. economy. Net HVAC exports grew by over 800 percent from 1987 to 1992 and currently exceed $2.6 billion annually (ARI 1994). Net gas cooling job and income creation are estimated using an economic input-output model to compare a reference case to a gas cooling scenario. The reference case reflects current policies, practices, and trends with respect to conventional electric cooling technologies. The gas cooling scenario examines the impact of accelerated use of natural gas cooling technologies here and abroad.

Technology Opportunities to Reduce U.S. Greenhouse Gas Emissions  

SciTech Connect

The rise in greenhouse gas emissions from fossil fuel combustion and industrial and agricultural activities has aroused international concern about the possible impacts of these emissions on climate. Greenhouse gases--mostly carbon dioxide, some methane, nitrous oxide and other trace gases--are emitted to the atmosphere, enhancing an effect in which heat reflected from the earth's surface is kept from escaping into space, as in a greenhouse. Thus, there is concern that the earth's surface temperature may rise enough to cause global climate change. Approximately 90% of U.S. greenhouse gas emissions from anthropogenic sources come from energy production and use, most of which are a byproduct of the combustion of fossil fuels. On a per capita basis, the United States is one of the world's largest sources of greenhouse gas emissions, comprising 4% of the world's population, yet emitting 23% of the world's greenhouse gases. Emissions in the United States are increasing at around 1.2% annually, and the Energy Information Administration forecasts that emissions levels will continue to increase at this rate in the years ahead if we proceed down the business-as-usual path. President Clinton has presented a two-part challenge for the United States: reduce greenhouse gas emissions and grow the economy. Meeting the challenge will mean that in doing tomorrow's work, we must use energy more efficiently and emit less carbon for the energy expended than we do today. To accomplish these goals, President Clinton proposed on June 26, 1997, that the United States ''invest more in the technologies of the future''. In this report to Secretary of Energy Pena, 47 technology pathways are described that have significant potential to reduce carbon dioxide emissions. The present study was completed before the December 1997 United Nations Framework Convention on Climate Change and is intended to provide a basis to evaluate technology feasibility and options to reduce greenhouse gas emissions. These technology pathways (which are described in greater detail in Appendix B, Technology Pathways) address three areas: energy efficiency, clean energy, and carbon sequestration (removing carbon from emissions and enhancing carbon storage). Based on an assessment of each of these technology pathways over a 30-year planning horizon, the directors of the Department of Energy's (DOE's) national laboratories conclude that success will require pursuit of multiple technology pathways to provide choices and flexibility for reducing greenhouse gas emissions. Advances in science and technology are necessary to reduce greenhouse gas emissions from the United States while sustaining economic growth and providing collateral benefits to the nation.

FY-2001 Accomplishments in Off-gas Treatment Technology Development  

SciTech Connect

This report summarizes the efforts funded by the Tank Focus Area to investigate nitrogen oxide (NOx) destruction (a.k.a. deNOx) technologies and off-gas scrubber system designs. The primary deNOx technologies that were considered are staged combustion (a.k.a. NOx reburning), selective catalytic reduction, selective non-catalytic reduction, and steam reformation. After engineering studies and a team evaluation were completed, selective catalytic reduction and staged combustion were considered the most likely candidate technologies to be deployed in a sodium-bearing waste vitrification facility. The outcome of the team evaluation factored heavily in the establishing a baseline configuration for off-gas and secondary waste treatment systems.

Mechanisms by Which Methane Gas and Methane Hydrate Coexist In Ocean Sediments Mechanisms by Which Methane Gas and Methane Hydrate Coexist In Ocean Sediments Mechanisms by Which Methane Gas and Methane Hydrate Coexist In Ocean Sediments Authors: Maša Prodanovic (speaker), Javad Behseresht, Yao Peng, Steven L. Bryant, Antone K. Jain and Ruben Juanes Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 ( http://www.spe.org and http://www.smenet.org [external sites] ) Abstract: A spectrum of behavior is encountered in methane hydrate provinces, especially ocean sediments, ranging from essentially static accumulations where the pore space is filled with hydrate and brine, to active seeps where hydrate and methane gas phase co-exist in the hydrate stability zone (HSZ). The grain-scale models of drainage and fracturing presented demonstrate key processes involved in pressure-driven gas phase invasion of a sediment. A novel extension of invasion percolation to infinite-acting, physically representative networks is used to evaluate the connectivity of water in a gas-drained sediment. A novel implementation of the level set method (LSM) is used to determine the capillarity-controlled displacement of brine by gas from sediment and from fractures within the sediment. The discrete element method (DEM) is extended to model the coupling between the pore fluids and the solid, and thereby predict the onset of sediment fracturing by gas phase pressure under in situ loading conditions. The DEM grain mechanics model accounts for the different pressure of brine and methane gas in a “membrane” two-fluid model. The fluid-fluid configuration from LSM can be mapped directly to the pore space in DEM, thereby coupling the drainage and mechanics models. The type of behavior that can emerge from the coupled processes is illustrated with an extended LSM model. The extension computes grain displacement by the gas phase with a simple kinematic rule.

Preparation of environmental analyses for synfuel and unconventional gas technologies  

DOE Green Energy (OSTI)

Government agencies that offer financial incentives to stimulate the commercialization of synfuel and unconventional gas technologies usually require an analysis of environmental impacts resulting from proposed projects. This report reviews potentially significant environmental issues associated with a selection of these technologies and presents guidance for developing information and preparing analyses to address these issues. The technologies considered are western oil shale, tar sand, coal liquefaction and gasification, peat, unconventional gas (western tight gas sands, eastern Devonian gas shales, methane from coal seams, and methane from geopressured aquifers), and fuel ethanol. Potentially significant issues are discussed under the general categories of land use, air quality, water use, water quality, biota, solid waste disposal, socioeconomics, and health and safety. The guidance provided in this report can be applied to preparation and/or review of proposals, environmental reports, environmental assessments, environmental impact statements, and other types of environmental analyses. The amount of detail required for any issue discussed must, by necessity, be determined on a case-by-case basis.

GE power generation technology challenges for advanced gas turbines  

SciTech Connect

The GE Utility ATS is a large gas turbine, derived from proven GEPG designs and integrated GEAE technology, that utilizes a new turbine cooling system and incorporates advanced materials. This system has the potential to achieve ATS objectives for a utility sized machine. Combined with use of advanced Thermal Barrier Coatings (TBC`s), the new cooling system will allow higher firing temperatures and improved cycle efficiency that represents a significant improvement over currently available machines. Developing advances in gas turbine efficiency and emissions is an ongoing process at GEPG. The third generation, ``F`` class, of utility gas turbines offers net combined cycle efficiencies in the 55% range, with NO{sub x} programs in place to reduce emissions to less than 10 ppM. The gas turbines have firing temperatures of 2350{degree}F, and pressure ratios of 15 to 1. The turbine components are cooled by air extracted from the cycle at various stages of the compressor. The heat recovery cycle is a three pressure steam system, with reheat. Throttle conditions are nominally 1400 psi and 1000{degree}F reheat. As part of GEPG`s ongoing advanced power generation system development program, it is expected that a gas fired advanced turbine system providing 300 MW power output greater than 58% net efficiency and < 10 ppM NO{sub x} will be defined. The new turbine cooling system developed with technology support from the ATS program will achieve system net efficiency levels in excess of 60%.

Technical Progress Report for the Gas Storage Technology Consortium  

Science Conference Proceedings (OSTI)

Gas storage is a critical element in the natural gas industry. Producers, transmission and distribution companies, marketers, and end users all benefit directly from the load balancing function of storage. The unbundling process has fundamentally changed the way storage is used and valued. As an unbundled service, the value of storage is being recovered at rates that reflect its value. Moreover, the marketplace has differentiated between various types of storage services, and has increasingly rewarded flexibility, safety, and reliability. The size of the natural gas market has increased and is projected to continue to increase towards 30 trillion cubic feet (TCF) over the next 10 to 15 years. Much of this increase is projected to come from electric generation, particularly peaking units. Gas storage, particularly the flexible services that are most suited to electric loads, is critical in meeting the needs of these new markets. In order to address the gas storage needs of the natural gas industry, an industry-driven consortium was created--the Gas Storage Technology Consortium (GSTC). The objective of the GSTC is to provide a means to accomplish industry-driven research and development designed to enhance operational flexibility and deliverability of the Nation's gas storage system, and provide a cost effective, safe, and reliable supply of natural gas to meet domestic demand. This report addresses the activities for the quarterly period of July 1, 2005 through September 30, 2005. During this time period efforts were directed toward (1) receiving proposals in response to the RFP, and (2) organizing and hosting the proposal selection meeting on August 30-31, 2005.

Much of this increase is projected to come from electric generation, particularly peaking units. Gas storage, particularly the flexible services that are most suited to electric loads, is critical in meeting the needs of these new markets. In order to address the gas storage needs of the natural gas industry, an industry-driven consortium was created--the Gas Storage Technology Consortium (GSTC). The objective of the GSTC is to provide a means to accomplish industry-driven research and development designed to enhance operational flexibility and deliverability of the Nation's gas storage system, and provide a cost effective, safe, and reliable supply of natural gas to meet domestic demand. This report addresses the activities for the quarterly period of October 1, 2005 through December 31, 2005. Activities during this time period were: (1) Nomination and election of Executive Council members for 2006-07 term, (2) Release the 2006 GSTC request-for-proposals (RFP), (3) Recruit and invoice membership for FY2006, (4) Improve communication efforts, and (5) Continue planning the GSTC spring meeting in San Diego, CA on February 21-22, 2006.

Decreasing Air Emission Impacts From Oil and Gas Development Decreasing Air Emission Impacts From Oil and Gas Development Decreasing Air Emission Impacts From Oil and Gas Development Authors: Charles B. McComas, PE; J. Daniel Arthur, PE; Gerry Baker; G. Lee Moody; and David B. Cornue, PG, CHMM Venue: American Chemical Society (53rd Pentasectional Meeting) – Halliburton Energy Services Technology Center, Duncan, OK, March 8, 2008 (http://www.acs.org [external site]) Abstract: Research funded by the United States Department of Energy’s National Energy Technology Laboratory and conducted under the direction of the Interstate Oil and Gas Compact Commission has examined concerns related to air emissions resulting from domestic onshore oil and gas exploration and production operations. Current air issues such as ambient air quality standards and non-attainment areas, regulatory compliance and regional inconsistencies, as well as global climate change and carbon sequestration are a few of the subjects perceived to represent potential barriers to energy development. The topic of air quality and how it relates to onshore oil and gas exploration and production activities is examined from the position of environmental sustainability. These concerns can be addressed through reasonable and prudent practices that industry may implement in order to avoid, minimize, or mitigate air emissions. Additionally, air emissions parameters that are not currently regulated (e.g.: CH4 and CO2) may become the subject of increased concern in the future and, therefore, add to the list of issues facing oil and gas exploration and production. Suggestions for further research opportunities with the potential to benefit responsible energy resource development are also presented.

Designing a Pilot-Scale Experiment for the Production of Natural Gas Hydrates and Sequestration of CO2 in Geologic Reservoirs Designing a Pilot-Scale Experiment for the Production of Natural Gas Hydrates and Sequestration of CO2 in Geologic Reservoirs Designing a Pilot-Scale Experiment for the Production of Natural Gas Hydrates and Sequestration of CO2 in Geologic Reservoirs Authors: Mark White and Pete McGrail Venue: The 9th International Conference on Greenhouse Gas Technologies will be held November 16-20, 2008 at The Omni Shoreham Hotel in Washington, DC. The Conference will be organized by MIT in collaboration with the IEA Greenhouse Gas R&D Programme (IEA GHG), with major sponsorship from the US Department of Energy. http://mit.edu/ghgt9/ . Abstract: Under high pressure and low temperature conditions small nonpolar molecules (typically gases) can combine with water to form crystalline structures known as clathrate hydrates. Methane (CH4) and carbon dioxide (CO2) form nearly identical clathrate structures (sI), with the CO2 hydrate being thermodynamically favored. Vast accumulations of methane hydrates have been found in suboceanic deposits and beneath the arctic permafrost. Because of the large volumetric storage densities, clathrate hydrates on the deep ocean floor have been suggested as a sequestration option for CO2. Alternatively, CO2 hydrates can be formed in the geologic settings of naturally occurring accumulations of methane hydrates. Global assessments of natural gas resources have shown that gas hydrate resources exceed those of conventional resources, which is indicative of the potential for clathrate hydrate sequestration of CO2. Recovery of natural gas from hydrate-bearing geologic deposits has the potential for being economically viable, but there remain significant technical challenges in converting these natural accumulations into a useable resource. Currently, conventional methods for producing methane hydrates from geologic settings include depressurization, thermal stimulation, and inhibitor injection. Although CO2 clathrates generally are not naturally as abundant as those of CH4, their occurrence forms the foundation of an unconventional approach for producing natural gas hydrates that involves the exchange of CO2 with CH4 in the hydrate structure. This unconventional concept has several distinct benefits over the conventional methods: 1) the heat of formation of CO2 hydrate is greater than the heat of dissociation of CH4 hydrate, providing a low-grade heat source to support additional methane hydrate dissociation, 2) exchanging CO2 with CH4 will maintain the mechanical stability of the geologic formation, and 3) the process is environmentally friendly, providing a sequestration mechanism for the injected CO2. The exchange production technology would not be feasible without the favorable thermodynamics of CO2 hydrates over CH4 hydrates. This situation yields challenges for the technology to avoid secondary hydrate formation and clogging of the geologic repository. Laboratory-scale experiments have demonstrated the feasibility of producing natural gas and sequestering CO2 using the direct exchange technology in geologic media. These experiments have duplicated numerically using the STOMP-HYD simulator, which solves the nonisothermal multifluid flow and transport equations for mixed hydrate systems in geologic media. This paper describes the design (via numerical simulation) of a pilot-scale demonstration test of the CO2 exchange production and sequestration technology for a geologic setting beneath the arctic permafrost, involving a gas-hydrate interval overlying a free-gas interval (i.e., Class 1 Hydrate Accumulation).

Development of Micro-Pattern Gas Detectors Technologies  

E-Print Network (OSTI)

The proposed R&D collaboration, RD51, aims at facilitating the development of advanced gas-avalanche detector technologies and associated electronic-readout systems, for applications in basic and applied research. Advances in particle physics have always been enabled by parallel advances in radiation-detector technology. Radiation detection and imaging with gas-avalanche detectors, capable of economically covering large detection volumes with a low material budget, have been playing an important role in many fields. Besides their widespread use in particle-physics and nuclear-physics experiments, gaseous detectors are employed in many other fields: astro-particle research and applications such as medical imaging, material science, and security inspection. While extensively employed at the LHC, RHIC, and other advanced HEP experiments, present gaseous detectors (wire-chambers, drift-tubes, resistive-plate chambers and others) have limitations which may prevent their use in future experiments.

Sizzling Qatar boom sparked by foreign money, technology, and gas  

Science Conference Proceedings (OSTI)

International oil companies have collected advanced upstream and downstream technology and focused it on the small Persian Gulf emirate of Qatar, a roughly 110 mile long by 50 mile wide, thumb-like peninsula that juts out from Saudi Arabia. The emirate, in a burst of enlightened self interest, has opened its doors to international companies and is now riding a wave of foreign investment and new technology to major increases in oil, natural gas, and petrochemical production. The largest natural gas reserve in the world is under Qatari waters and is the driver for the activity that includes two LNG plants. Qatar has proven that you don`t need crude oil in the Persian Gulf to be important. Activities are discussed.

Strategies for the Commercialization and Deployment of Greenhouse Gas Intensity-Reducing Technologies and Practices  

Science Conference Proceedings (OSTI)

New technologies will be a critical component--perhaps the critical component--of our efforts to tackle the related challenges of energy security, climate change, and air pollution, all the while maintaining a strong economy. But just developing new technologies is not enough. Our ability to accelerate the market penetration of clean energy, enabling, and other climate-related technologies will have a determining impact on our ability to slow, stop, and reverse the growth in greenhouse gas (GHG) emissions. Title XVI, Subtitle A, of the Energy Policy Act of 2005 (EPAct 2005) directs the Administration to report on its strategy to promote the commercialization and deployment (C&D) of GHG intensity-reducing technologies and practices. The Act also requests the Administration to prepare an inventory of climate-friendly technologies suitable for deployment and to identify the barriers and commercial risks facing advanced technologies. Because these issues are related, they are integrated here within a single report that we, representing the Committee on Climate Change Science and Technology Integration (CCCSTI), are pleased to provide the President, the Congress, and the public. Over the past eight years, the Administration of President George W. Bush has pursued a series of policies and measures aimed at encouraging the development and deployment of advanced technologies to reduce GHG emissions. This report highlights these policies and measures, discusses the barriers to each, and integrates them within a larger body of other extant policy. Taken together, more than 300 policies and measures described in this document may be viewed in conjunction with the U.S. Climate Change Technology Program's (CCTP's) Strategic Plan, published in September 2006, which focuses primarily on the role of advanced technology and associated research and development (R&D) for mitigating GHG emissions. The CCTP, a multi-agency technology planning and coordination program, initiated by President Bush, and subsequently authorized in EPAct2005, is responsible for preparing this report on behalf CCCSTI. This report systematically examines the market readiness of key technologies important to meeting climate change mitigation goals. It assesses the barriers and business risks impeding their progress and greater market application. Importantly, by documenting the hundreds of Federal policies, programs, regulations, incentives, and other activities that are in effect and operating today to address these barriers, it provides a broad context for evaluating the adequacy of current policy and the potential need, if any, for additional measures that might be undertaken by government or industry. Finally, it draws conclusions about the current situation, identifies gaps and opportunities, and suggests analytical principles that should be applied to assess and formulate policies and measures to accelerate the commercialization and deployment of these technologies.

Assessment of Gas Turbine Compressor Health Monitoring Technologies: Interim Report  

Science Conference Proceedings (OSTI)

A major risk item in gas turbine machinery is compressor rotor/stator blade failure, which can lead to the downstream propagation of components through the compressor. Several events of this nature have occurred over the last few years, in some cases causing catastrophic damage to the entire compressor. In response to these issues, a number of compressor monitoring approaches have been proposed, with different degrees of commercial penetration and technological readiness. The simplest approach is to ...

New generation enrichment monitoring technology for gas centrifuge enrichment plants  

SciTech Connect

The continuous enrichment monitor, developed and fielded in the 1990s by the International Atomic Energy Agency, provided a go-no-go capability to distinguish between UF{sub 6} containing low enriched (approximately 4% {sup 235}U) and highly enriched (above 20% {sup 235}U) uranium. This instrument used the 22-keV line from a {sup 109}Cd source as a transmission source to achieve a high sensitivity to the UF{sub 6} gas absorption. The 1.27-yr half-life required that the source be periodically replaced and the instrument recalibrated. The instrument's functionality and accuracy were limited by the fact that measured gas density and gas pressure were treated as confidential facility information. The modern safeguarding of a gas centrifuge enrichment plant producing low-enriched UF{sub 6} product aims toward a more quantitative flow and enrichment monitoring concept that sets new standards for accuracy stability, and confidence. An instrument must be accurate enough to detect the diversion of a significant quantity of material, have virtually zero false alarms, and protect the operator's proprietary process information. We discuss a new concept for advanced gas enrichment assay measurement technology. This design concept eliminates the need for the periodic replacement of a radioactive source as well as the need for maintenance by experts. Some initial experimental results will be presented.

Gas and Oil in Utah: Potential, New Discoveries, and Hot Plays Gas and Oil in Utah: Potential, New Discoveries, and Hot Plays Gas and Oil in Utah: Potential, New Discoveries, and Hot Plays Author: Thomas C. Chidsey, Petroleum Section Chief, Utah Geological Survey, Salt Lake City, UT. Venue: International Oil Scouts Association’s 84th annual meeting, Stein Eriksen Lodge, Park City, UT, June 17–20, 2007, (http://www.oilscouts.com/index-main.html [external site]). Abstract: Utah’s natural gas and oil exploration history extends back more than 100 years, fluctuating greatly due to discoveries, price trends, and changing exploration targets. During the boom period of the early 1980s, activity peaked at over 500 wells per year. After slowing in the 1990s, drilling activity has again increased, reaching an all-time peak of 1,058 wells spudded and over 2,000 APDs (application for permit to drill) filed in 2006. This increase in activity has been spurred by high prices for both natural gas and oil and by the perception that Utah is highly prospective and underexplored. In recent years, the proportion of new wells exploring for gas has increased greatly. Total cumulative natural gas production from Utah fields now exceeds 8 Tcf. Recent successful drilling has been expanding reserves by about 10 percent per year, one of the highest rates of gas reserves increase in the country. Although gas production from some fields declined during the late 1990s, two factors caused overall gas production to increase. The development of coalbed natural gas (CBNG) accumulations in the Cretaceous Ferron Sandstone play, in particular Drunkards Wash field in central Utah, has increased the State’s annual gas production by 20–30 percent. Also, deeper exploratory and development drilling in the eastern and southern Uinta Basin during the past 5 years has led to discoveries of substantial gas accumulations in tight-sand reservoirs of the Tertiary Wasatch Formation, Cretaceous Mesaverde Group, and Jurassic Entrada and Wingate Sandstones. Significant potential exists for other coalfields (Book Cliffs, Sego, and Wasatch Plateau) around the Uinta Basin to yield CBNG, and the extent of deeper conventional and tight-gas plays remains to be explored. In addition, shale gas reservoirs in the Mississippian Manning Canyon Shale, Pennsylvanian Hermosa Group, and Cretaceous Mancos Shale of central, southeastern, and northeastern Utah, respectively, have tremendous untapped potential. Utah oilfields have produced a cumulative total of 1.3 billion barrels (bbl) of oil. Although annual production decreased from a peak of 41 million bbl in 1985 to 13 million bbl in 2003, the trend has since reversed, and 2005 production reached nearly 17 million bbl. A component (about one-third of the increase) of this turnaround has been the 2004 discovery of Covenant field in the central Utah thrust belt, or "Hingeline." This new field has already produced 3 million bbl of Mississippian-sourced oil from the Jurassic Navajo Sandstone in a thrusted anticline formed during the Sevier orogeny. This new oil play is the focus of extensive leasing and exploration activity—comparable to the late 1970s and early 1980s in the Utah-Wyoming salient of the thrust belt to the north.

Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Authors: Mohamed Toema (speaker), Sarah Nuss-Warren, and Kirby S. Chapman, Kansas State University National Gas Machinery Laboratory; James McCarthy and Thomas McGrath, Innovative Environmental Solutions Inc. Venue: ASME Internal Combustion Engine Division 2009 Spring Technical Conference, May 3–6, Milwaukee, WI. http://www.asmeconferences.org/ICES09/index.cfm [external site]. Abstract: The researchers are conducting a project to characterize pollutant emissions performance of field gas-fired four-stroke cycle rich burn engines equipped with non-selective catalytic reduction (NSCR) technology. Engine emissions and operating parameters are being monitored on three engines over an extended period. In addition, a mapping study was conducted on one engine. The NSCR was operated at various controlled air-to-fuel (AF) ratios while emission measurements were conducted and engine operating parameters monitored. NOx, CO, and oxygen were measured using both EPA reference method technology and the portable analyzer used in the long-term study. In the mapping study, ammonia, formaldehyde, CO, NOx, and speciated hydrocarbon emissions were recorded in real-time using an extractive FTIR system. This paper focuses on the engine mapping phase. The mapping tests demonstrated a trade-off between NOx emissions and CO, ammonia, and hydrocarbon emissions. Richer engine operation (lower AF) decreases NOx emissions at the expense of higher CO, ammonia, and hydrocarbons. Leaner operation has the opposite effect. The results to date of the semi-continuous monitoring are presented in a separate paper.

BENCH-SCALE DEMONSTRATION OF HOT-GAS DESULFURIZATION TECHNOLOGY  

SciTech Connect

The U.S. Department of Energy (DOE), Federal Energy Technology Center (FETC), is sponsoring research in advanced methods for controlling contaminants in hot coal gasifier gas (coal-derived fuel-gas) streams of integrated gasification combined-cycle (IGCC) power systems. The hot gas cleanup work seeks to eliminate the need for expensive heat recovery equipment, reduce efficiency losses due to quenching, and minimize wastewater treatment costs. Hot-gas desulfurization research has focused on regenerable mixed-metal oxide sorbents that can reduce the sulfur in coal-derived fuel-gas to less than 20 ppmv and can be regenerated in a cyclic manner with air for multicycle operation. Zinc titanate (Zn{sub 2} TiO{sub 4} or ZnTiO{sub 3}), formed by a solid-state reaction of zinc oxide (ZnO) and titanium dioxide (TiO{sub 2}), is currently one of the leading sorbents. Overall chemical reactions with Zn{sub 2} TiO{sub 4} during the desulfurization (sulfidation)-regeneration cycle are shown below: Sulfidation: Zn{sub 2} TiO{sub 4} + 2H{sub 2}S {yields} 2ZnS + TiO{sub 2} + 2H{sub 2}O; Regeneration: 2ZnS + TiO{sub 2} + 3O{sub 2} {yields} Zn{sub 2} TiO{sub 4} + 2SO{sub 2} The sulfidation/regeneration cycle can be carried out in a fixed-bed, moving-bed, or fluidized-bed reactor configuration. The fluidized-bed reactor configuration is most attractive because of several potential advantages including faster kinetics and the ability to handle the highly exothermic regeneration to produce a regeneration offgas containing a constant concentration of SO{sub 2}.

Economical analysis of a new gas to ethylene technology  

E-Print Network (OSTI)

Ethylene is one of the most important petrochemical intermediates and feedstocks for many different products. The motivating force of this work is to compare a new process of ethylene production developed at Texas A&M University to the most common processes. Ethylene is produced commercially using a wide variety of feedstocks ranging from ethane to heavy fuel oils. Of them, the thermal cracking of ethane and propane using a fired tubular heater is the most common process in the United States. In Europe and Japan, where natural gas is not abundant, thermal cracking of naphtha using a fired heater is the most common process. In addition to these processes; ethylene could also be produced from crude oil by autothermic and fluidized bed techniques and from coal and heavy oils by synthesis from carbon monoxide and hydrogen. At Texas A&M University, a group of researchers developed a new process that can convert natural gas into liquids (GTL) or to ethylene (GTE). This technology is a direct conversion method that does not require producing syngas. When selecting a process for ethylene production, the dominant factor is the selection of hydrocarbon feedstocks. Based upon plant capacity of 321 million pounds of ethylene per year, this study has shown that using natural gas, as a feedstock, is more economical than using ethane, propane, naphtha, and other feedstocks. Therefore, it is more economical to convert natural gas directly to ethylene than separating ethane or propane from natural gas and then converting it to ethylene. A process simulation package ProMax is used to run the GTE process; and a software program, Capcost, is used to evaluate fixed capital costs of the GTE process. Finally, the cost index is used to update the cost of the other processes of ethylene production today.

Advanced Hydraulic Fracturing Technology for Unconventional Tight Gas Reservoirs  

Science Conference Proceedings (OSTI)

The objectives of this project are to develop and test new techniques for creating extensive, conductive hydraulic fractures in unconventional tight gas reservoirs by statistically assessing the productivity achieved in hundreds of field treatments with a variety of current fracturing practices ranging from 'water fracs' to conventional gel fracture treatments; by laboratory measurements of the conductivity created with high rate proppant fracturing using an entirely new conductivity test - the 'dynamic fracture conductivity test'; and by developing design models to implement the optimal fracture treatments determined from the field assessment and the laboratory measurements. One of the tasks of this project is to create an 'advisor' or expert system for completion, production and stimulation of tight gas reservoirs. A central part of this study is an extensive survey of the productivity of hundreds of tight gas wells that have been hydraulically fractured. We have been doing an extensive literature search of the SPE eLibrary, DOE, Gas Technology Institute (GTI), Bureau of Economic Geology and IHS Energy, for publicly available technical reports about procedures of drilling, completion and production of the tight gas wells. We have downloaded numerous papers and read and summarized the information to build a database that will contain field treatment data, organized by geographic location, and hydraulic fracture treatment design data, organized by the treatment type. We have conducted experimental study on 'dynamic fracture conductivity' created when proppant slurries are pumped into hydraulic fractures in tight gas sands. Unlike conventional fracture conductivity tests in which proppant is loaded into the fracture artificially; we pump proppant/frac fluid slurries into a fracture cell, dynamically placing the proppant just as it occurs in the field. From such tests, we expect to gain new insights into some of the critical issues in tight gas fracturing, in particular the roles of gel damage, polymer loading (water-frac versus gel frac), and proppant concentration on the created fracture conductivity. To achieve this objective, we have designed the experimental apparatus to conduct the dynamic fracture conductivity tests. The experimental apparatus has been built and some preliminary tests have been conducted to test the apparatus.

Variation in Long-Term Emissions Data from NSCR-Equipped Natural Gas-Fueled Engine Variation in Long-Term Emissions Data from NSCR-Equipped Natural Gas-Fueled Engine Variation in Long-Term Emissions Data from NSCR-Equipped Natural Gas-Fueled Engine Authors: Kirby S. Chapman (speaker), Mohamed Toema, and Sarah Nuss-Warren, Kansas State University National Gas Machinery Laboratory. Venue: ASME Internal Combustion Engine Division 2009 Spring Technical Conference, May 3–6, Milwaukee, WI. http://www.asmeconferences.org/ICES09/index.cfm [external site]. Abstract: This paper describes work on a project to characterize pollutant emissions performance of non-selective catalytic reduction (NSCR) technology, including a catalyst and air-to-fuel ratio controller (AFRC), applied to four-stroke cycle rich-burn engines. Emissions and engine data were collected semi-continuously with a portable emissions analyzer on three engines in the Four Corners area. In addition, periodic emissions measurements that included ammonia were conducted several times. Data collected from October 2007 through August 2008 show significant variation in emissions levels over hours, days, and longer periods of time, as well as seasonal variation. As a result of these variations, simultaneous control of NOx to below a few hundred parts per million (ppm) and CO to below 1,000 ppm volumetric concentration was not consistently achieved. Instead, the NSCR/AFRC systems were able to simultaneously control both species to these levels for only a fraction of the time the engines were monitored. Both semi-continuous emissions data and periodically collected emissions data support a NOx-CO trade-off and a NOx-ammonia tradeoff in NSCR-equipped engines.

Technology and Greenhouse Gas Emissions: An IntegratedScenario Analysis  

SciTech Connect

This report describes an analysis of possible technology-based scenarios for the U.S. energy system that would result in both carbon savings and net economic benefits. We use a modified version of the Energy Information Administration's National Energy Modeling System (LBNL-NEMS) to assess the potential energy, carbon, and bill savings from a portfolio of carbon saving options. This analysis is based on technology resource potentials estimated in previous bottom-up studies, but it uses the integrated LBNL-NEMS framework to assess interactions and synergies among these options. The analysis in this paper builds on previous estimates of possible "technology paths" to investigate four major components of an aggressive greenhouse gas reduction strategy: (1) the large scale implementation of demand-side efficiency, comparable in scale to that presented in two recent policy studies on this topic; (2) a variety of "alternative" electricity supply-side options, including biomass cofiring, extension of the renewable production tax credit for wind, increased industrial cogeneration, and hydropower refurbishment. (3) the economic retirement of older and less efficient existing fossil-find power plants; and (4) a permit charge of $23 per metric ton of carbon (1996 $/t),l assuming that carbon trading is implemented in the US, and that the carbon permit charge equilibrates at this level. This level of carbon permit charge, as discussed later in the report, is in the likely range for the Clinton Administration's position on this topic.

Natural gas and efficient technologies: A response to global warming  

DOE Green Energy (OSTI)

It has become recognized by the international scientific community that global warming due to fossil fuel energy buildup of greenhouse CO{sub 2} in the atmosphere is a real environmental problem. Worldwide agreement has also been reached to reduce CO{sub 2} emissions. A leading approach to reducing CO{sub 2} emissions is to utilize hydrogen-rich fuels and improve the efficiency of conversion in the power generation, transportation and heating sectors of the economy. In this report, natural gas, having the highest hydrogen content of all the fossil fuels, can have an important impact in reducing CO{sub 2} emissions. This paper explores natural gas and improved conversion systems for supplying energy to all three sectors of the economy. The improved technologies include combined cycle for power generation, the Carnol system for methanol production for the transportation sector and fuel cells for both power generation and transportation use. The reduction in CO{sub 2} from current emissions range from 13% when natural gas is substituted for gasoline in the transportation sector to 45% when substituting methanol produced by the Carnol systems (hydrogen from thermal decomposition of methane reacting with CO{sub 2} from coal-fired power plants) used in the transportation sector. CO{sub 2} reductions exceeding 60% can be achieved by using natural gas in combined cycle for power generation and Carnol methanol in the transportation sector and would, thus, stabilize CO{sub 2} concentration in the atmosphere predicted to avoid undue climate change effects. It is estimated that the total fossil fuel energy bill in the US can be reduced by over 40% from the current fuel bill. This also allows a doubling in the unit cost for natural gas if the current energy bill is maintained. Estimates of the total net incremental replacement capital cost for completing the new improved equipment is not more than that which will have to be spent to replace the existing equipment conducting business as usual.

Moridis, and Tarun Grover Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 ( http://www.spe.org and http://www.smenet.org [external sites] ) Abstract: This study investigated coupled multiphase flow, themal, thermodynamic and geomechanical behavior of oceanic Hydrate Bearing Sediments (HBS), during depressurization-induced gas production in general, and potential wellbore in-stability and casing deformation in particular. The project investigated the geomechanical changes and wellbore stability for two alternative cases of production using a horizontal well in a Class 3 deposit and a vertical well in a Class 2 deposit. The research compared the geomechanical responses and the potential adverse geomechanical effects for the two different cases. Analysis shows that geomechanical responses during depressurization-induced gas production from oceanic hydrate deposits is driven by the reservoir-wide pressure decline (Delta P), which in turn is controlled by the induced pressure decline near the wellbore. Because any change quickly propagates within the entire reservoir, the reservoir wide geomechanical response can occur within a few days of production induced pressure decline.

Science Conference Proceedings (OSTI)

Natural gas represents an important energy source for the United States. According to the U.S. Department of Energy's (DOE's) Energy Information Administration (EIA), about 22% of the country's energy needs are provided by natural gas. Historically, natural gas was produced from conventional vertical wells drilled into porous hydrocarbon-containing formations. During the past decade, operators have increasingly looked to other unconventional sources of natural gas, such as coal bed methane, tight gas sands, and gas shales.

Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Field Evaluation of a Surfactant-Modified Zeolite System for Removal of Organics from Produced Water Authors: Robert S. Bowman, New Mexico Technological University, Socorro, NM; Enid J. Sullivan, Los Alamos National Laboratory, Los Alamos, NM; and Lynn E. Katz and Kerry A. Kinney, University of Texas, Austin, TX. Venue: 44th Annual Meeting of the Clay Minerals Society in Santa Fe, NM, June 3–7, 2007 (http://www.clays.org/home/HomeAnnualMeeting.html [external site]). Abstract: About 2.3 billion cubic meters (600 billion gallons) of wastewater (produced water) is generated each year as a byproduct of oil and gas operations in the continental United States. Disposal of this water represents about 10% of the cost of hydrocarbon production. Inexpensive treatment technologies can lower the cost of disposal and generate higher-quality water for other uses. Surfactant-modified zeolite (SMZ) has been shown to effectively sorb a variety of nonpolar organic compounds from water. SMZ was tested as a medium to remove benzene, toluene, ethylbenzene, and xylenes (BTEX) from produced water generated during extraction of coalbed natural gas. BTEX removal is necessary prior to surface discharge of produced waters or as a pretreatment for reverse osmosis. We demonstrated in laboratory column experiments that BTEX-saturated SMZ is readily regenerated by air sparging. There was no loss in BTEX sorption capacity, and a minor decrease in hydraulic conductivity, after 50 sorption/regeneration cycles. Based upon the laboratory results, a pilot-scale produced-water treatment system was designed and tested at a reinjection facility in the San Juan Basin of New Mexico. The SMZ-based system was designed to treat up to 110 liters (30 gallons) of produced water per hour on a continuous basis by running two SMZ columns in series. The system performed as predicted, based on laboratory results, over repeated feed and regeneration cycles during the month-long operation. The BTEX-laden sparge gases were treated with a vapor-phase bioreactor system, resulting in an emissions-free process

Numerical Studies of Geomechanical Stability of Hydrate-Bearing Sediments Numerical Studies of Geomechanical Stability of Hydrate-Bearing Sediments Authors: George J. Moridis, Jonny Rutqvist, Lawrence Berkeley National Laboratory. Venue: 2007 Offshore Technology Conference, Houston, TX, April 30–May 1, 2007 (http://www.otcnet.org/ [external site]). Abstract: The thermal and mechanical loading of hydrate-bearing sediments (HBS) can result in hydrate dissociation and a significant pressure increase, with potentially adverse consequences on the integrity and stability of the wellbore assembly, the HBS, and the bounding formations. The perception of HBS instability, coupled with insufficient knowledge of their geomechanical behavior and the absence of predictive capabilities, has resulted in a strategy of avoidance of HBS when locating offshore production platforms. These factors can also impede the development of hydrate deposits as gas resources. For the analysis of the geomechanical stability of HBS, project researchers developed and used a numerical model that integrates a commercial geomechanical code into a simulator describing the coupled processes of fluid flow, heat transport, and thermodynamic behavior in geologic media. The geomechanical code includes elastoplastic models for quasi-static yield and failure analysis and viscoplastic models for time-dependent (creep) analysis. The hydrate simulator can model the non-isothermal hydration reactions (equilibrium or kinetic), phase behavior, and flow of fluids and heat in HBS, and can handle any combination of hydrate dissociation mechanisms. The simulations can account for the interdependence of changes in the hydraulic, thermodynamic, and geomechanical properties of the HBS, in addition to swelling/shrinkage, displacement (subsidence), and possible geomechanical failure. Researchers investigated in three cases the coupled hydraulic, thermodynamic, and geomechanical behavior of oceanic HBS systems. The first involves hydrate heating as warm fluids from deeper, conventional reservoirs ascend to the ocean floor through uninsulated pipes intersecting the HBS. The second case involves mechanical loading caused by the weight of structures placed on HBS at the ocean floor, and the third describes system response during gas production from a hydrate deposit. The results indicate that the stability of HBS in the vicinity of warm pipes may be significantly affected, especially near the ocean floor where the sediments are unconsolidated and more compressible. Conversely, the increased pressure caused by the weight of structures on the ocean floor increases the stability of hydrates, while gas production from oceanic deposits minimally affects the geomechanical stability of HBS under the conditions that are deemed desirable for production.

Syngas Processing Systems Syngas Processing Systems Advanced Acid Gas Separation Technology for Clean Power and Syngas Applications Air Products and Chemicals, Inc. Project Number: FE0013363 Project Description In this project, Air Products will operate a two-bed mobile system at the National Carbon Capture Center (NCCC) facility. A slipstream of authentic, high-hydrogen syngas based on low-rank coal will be evaluated as the feedstock. Testing will be conducted for approximately eight weeks, thereby providing far longer adsorbent exposure data than demonstrated to date. By utilizing real-world, high- hydrogen syngas, information necessary to understand the utility of the system for methanol production will be made available. In addition, Air Products will also operate a multi-bed PSA process development unit (PDU), located at its Trexlertown, PA headquarters, to evaluate the impact of incorporating pressure equalization steps in the process cycle. This testing will be conducted utilizing a sulfur-free, synthetic syngas, and will improve the reliability of the prediction of the system's operating performance at commercial scale.

Kneafsey (speaker), Yongkoo Seol, Arvind Gupta, and Liviu Tomutsa Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 http://www.spe.org and http://www.smenet.org [external sites] Abstract: Methane hydrate was formed in moist sand under confining stress in a long, x-ray transparent pressure vessel. Three initial water saturations were used to form three different methane hydrate saturations. X-ray computed tomography (CT) was used to observe location-specific density changes, caused by hydrate formation and flowing water. Gas permeability was measured in each test for dry sand, moist sand, frozen sand, and hydrate-bearing sand. Results of these measurements are presented. Water was flowed through the hydrate-bearing sand, and the changes in water saturation were observed using CT scanning. Inverse modeling will be performed using these data to extend the relative permeability measurements

Characterization of Nonequilibrium Sorption of Gasoline Components by Surfactant-Modified Zeolite Characterization of Nonequilibrium Sorption of Gasoline Components by Surfactant-Modified Zeolite Characterization of Nonequilibrium Sorption of Gasoline Components by Surfactant-Modified Zeolite Authors: Joshua A. Simpson and Robert S. Bowman, New Mexico Technological University, Socorro, NM Venue: 44th Annual Meeting of the Clay Minerals Society in Santa Fe, NM, June 3–7, 2007 (http://www.clays.org/home/HomeAnnualMeeting.html [external site]). Abstract: Surfactant-modified zeolite (SMZ) has been shown to effectively remove benzene, toluene, ethylbenzene, and xylene (BTEX) from water generated during oil and natural gas production (produced water). The BTEX sorption isotherms are linear and noncompetitive, suggesting that the removal mechanism is partitioning into the surfactant’s hydrophobic bilayer formed on SMZ. Even though BTEX sorption in batch systems is rapid, chemical equilibrium models do not accurately describe BTEX transport through packed beds of SMZ. Comparison with transport of a nonreactive tracer (tritium) suggests that two-site, diffusive nonequilibrium sorption-desorption controls BTEX transport. We conducted batch experiments with SMZ to determine the nonequilibrium sorption kinetics of each BTEX constituent. The kinetic measurements were used to parameterize a nonequilibrium transport model to predict BTEX removal under varying flow conditions. The accuracy of predictions is being tested using laboratory column experiments with produced water from the San Juan Basin of New Mexico

Mechanical strength and seismic property measurements of hydrate-bearing sediments Mechanical strength and seismic property measurements of hydrate-bearing sediments Mechanical strength and seismic property measurements of hydrate-bearing sediments (HBS) during hydrate formation and loading tests (OTC 19559) Authors: Seiji Nakagawa (speaker), Timothy J. Kneafsey, and George J. Moridis Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 http://www.spe.org and http://www.smenet.org [external sites] Abstract: An on-going effort on conducting laboratory triaxial compression tests on synthetic methane hydrate-bearing sediment cores is presented. Methane hydrate is formed within a sand pack inside a test cell under controlled temperature and confining stress, and triaxial compression tests are performed while monitoring seismic properties. A unique aspect of the experiment is that the formation and dissociation of hydrate in a sediment core, and the failure of the sample during loading tests, can be monitored in real time using both seismic waves and x-ray CT imaging. For this purpose, a specially designed triaxial (geomechanical) test cell was built. This cell allows for conducting seismic wave measurements on a sediment core using compressional and shear (torsion) waves. Concurrently, CT images can be obtained through an x-ray-transparent cell wall. These are used to determine the porosity distribution within a sample owing to both original sand packing and formation of hydrate in the pore space. For interpreting the results from both seismic measurements and geomechanical tests, characterization of sample heterogeneity can be critically important. In this paper, the basic functions of the test cell are presented, with the results of preliminary experiments using non-hydrate bearing sandpack and sandstone core. These measurements confirmed that (1) clear x-ray images of gas-fluid boundaries within a sediment/rock core can be obtained through a thick aluminum test cell wall, (2) the test cell functions correctly during loading tests, and (3) both compressional and shear waves can be measured during a loading test. Further experiments using methane-hydrate-bearing samples will be presented at the conference

DOE Technology Successes - "Breakthrough" Gas Turbines DOE Technology Successes - "Breakthrough" Gas Turbines DOE Technology Successes - "Breakthrough" Gas Turbines For years, gas turbine manufacturers faced a barrier that, for all practical purposes, capped power generating efficiencies for turbine-based power generating systems. The barrier was temperature. Above 2300 degrees F, available cooling technologies were insufficient to protect the turbine blades and other internal components from heat degradation. Since higher temperatures are the key to higher efficiencies, this effectively limited the generating efficiency at which a turbine power plant could convert the energy in the fuel into electricity. The Department of Energy's Office of Fossil Energy took on the challenge of turbine temperatures in 1992, and nine years later, its private sector

Venue: American Geophysical Union fall meeting, San Francisco, CA, December 10-14, 2007 (http://www.agu.org/meetings/fm07/ [external site]). Abstract: A spectrum of behavior is encountered in ocean sediments bearing methane hydrates, ranging from essentially static accumulations where hydrate and brine co-exist, to active cold seeps where hydrate and a methane gas phase co-exist in the hydrate stability zone (HSZ). In this and a companion paper (Jain and Juanes), the researchers describe methods to test the following hypothesis: The coupling between drainage and fracturing, both induced by pore pressure, determines whether methane gas entering the HSZ is converted completely to hydrate. The researchers will describe a novel implementation of the level set method to determine the capillarity-controlled displacement of brine by gas from sediment and from fractures within the sediment. Predictions of fluid configurations in infinite-acting-model sediments indicate that the brine in drained sediment (after invasion by methane gas) is better connected than previously believed. This increases the availability of water and the rate of counter-diffusion of salinity ions, thus relaxing the limit on hydrate build-up within the gas-invaded grain matrix. Simulated drainage of a fracture in sediment shows that points of contact between fracture faces are crucial. They allow residual water saturation to remain within an otherwise gas-filled fracture. Simulations of imbibition—which can occur, for example, after drainage into surrounding sediment reduces gas phase pressure in the fracture—indicate that the gas/water interfaces at contact points significantly shift the threshold pressures for withdrawal of gas. During both drainage and imbibition, the contact points greatly increase water availability for hydrate formation within the fracture. The researchers will discuss coupling this capillarity-controlled displacement model with a discrete element model for grain-scale mechanics. The coupled model provides a basis for evaluating the macroscopic conditions (thickness of gas accumulation below the hydrate stability zone, average sediment grain size, principal earth stresses) favoring co-existence of methane gas and hydrate in the HSZ.

Reactive transport modeling of oceanic gas hydrate instability and dissociation in response to climate change Reactive transport modeling of oceanic gas hydrate instability and dissociation in response to climate change Reactive transport modeling of oceanic gas hydrate instability and dissociation in response to climate change Authors: Matthew T. Reagan and George J. Moridis Venue: 6th International Conference on Gas Hydrates 2008, Vancouver, British Columbia, July 9-12, 2008 (http://www.icgh.org [external site]) Abstract: Paleoceanographic evidence has been used to postulate that methane from oceanic hydrates may have had a significant role in regulating past global climate. The implication is that global oceanic deposits of methane gas hydrate is the main culprit for a sequence of rapid global warming affects that occurred during the late Quaternary period. However, the behavior of contemporary oceanic methane hydrate deposits subjected to rapid temperature changes, like those predicted under future climate change scenarios, is poorly understood. To determine the fate of the carbon stored in these hydrates, we performed coupled thermo-hydrological-chemical simulations of oceanic gas hydrate accumulations subjected to temperature changes at the seafloor, and assessed the potential for methane release into the ecosystem. Our modeling analysis considered the properties of benthic sediments, the saturation and distribution of the hydrates, the ocean depth, the initial seafloor temperature, and the effects of benthic biogeochemical activity. The results show that while many deep hydrate deposits are indeed stable during periods of rapid ocean temperature changes, shallow deposits (such as those found in arctic regions or in the Gulf of Mexico) can undergo rapid dissociation and produce significant carbon fluxes over a period of decades. These fluxes may exceed the ability of the seafloor environment (via anaerobic oxidation of methane and the formation of carbonates) to sequester the released carbon. This model will provide a source term to regional or global climate models in order to assess the coupling of gas hydrate deposits to changes in the global climate.

Production Strategies for Marine Hydrate Reservoirs Production Strategies for Marine Hydrate Reservoirs Production Strategies for Marine Hydrate Reservoirs Authors: J. Phirani. & K. K. Mohanty Venue: 6th International Conference on Gas Hydrates (ICGH 2008), Vancouver, British Columbia, CANADA, July 6-10, 2008. http://www.ichg.org/showcontent.aspx?MenuID=287 [external site]. Abstract: Large quantities of natural gas hydrate are present in marine sediments. This research is aimed at assessing production of natural gas from these deposits. We had developed a multiphase, multicomponent, thermal, 3D simulator in the past, which can simulate production of hydrates both in equilibrium and kinetic modes. Four components (hydrate, methane, water and salt) and five phases (hydrate, gas, aqueous-phase, ice and salt precipitate) are considered in the simulator. The intrinsic kinetics of hydrate formation or dissociation is considered using the Kim–Bishnoi model. Water freezing and ice melting are tracked with primary variable switch method (PVSM) by assuming equilibrium phase transition. In this work, we simulate depressurization and warm water flooding for hydrate production in a hydrate reservoir underlain by a water layer. Water flooding has been studied as a function of well spacing, well orientation, and injection temperature. Results show that depressurization is limited by the supply of heat of hydrate formation. Warm water flooding can supply this heat of formation. Gas production rate is higher for the water flooding than depressurization. Optimum configuration for wells and water temperature are identified.

Physical properties of sediment from the 2006 National Gas Hydrate Program expedition offshore India Physical properties of sediment from the 2006 National Gas Hydrate Program expedition offshore India Physical properties of sediment from the 2006 National Gas Hydrate Program expedition offshore India Authors: Winters, W.J., (U.S. Geological Survey, speaker), Gomes, M., Giosan, L., Johnson, J., Kastner, M., Torres, M.E., Long, P.E., Schaef, H.T., Rose, K., and the NGHP-01 Shipboard Scientific Party. Venue: India’s Directorate General of Hydrocarbons’ International Conference on Gas Hydrates in Nodia (New Delhi), India, February 6–8, 2008 (http://www.dghindia.org/site/pdfattachments/upcomingevents/Updated_Programme_gAS[1].pdf [PDF-external site]). Abstract: The scientific goals of the NGHP Expedition 01 physical properties program are to a) constrain baseline index properties of host sediment; b) ground-truth well-log, seismic, and other shipboard data sets; c) relate textural characteristics to gas hydrate occurrence and small-scale porous media effects; and d) relate index properties and textural analyses to gas hydrate occurrence and regional sedimentologic interpretations. During the shipboard phase of NGHP-01, baseline bulk physical properties, such as water content, grain density, bulk density, and porosity, were determined on more than 1,800 sediment samples from 14 sites located in four study areas. Overall, physical properties change more significantly near the seafloor, then at a much more gradual rate with depth. The transition depth varies between sites but can range from about 12 to as deep as 200 meters beneath the seafloor. In addition, shear strength, electrical resistivity, magnetic susceptibility, thermal conductivity, and acoustic velocity measurements were conducted to further characterize the sediment. These measurements, when combined with sedimentologic and geochemical studies, delineate the role of the host sediment in hydrate formation and occurrence and are used in modeling the response of hydrate-bearing sediment to natural change or drilling operations. Strong correlation typically exists between physical properties determined from shipboard analyses and well-log studies. More than 500 shore-based grain-size analyses have been conducted that indicate that most sediment is characterized as clayey silt to silty clay with a median grain size that is near or slightly greater than the silt-clay boundary. Grain-size analyses are being conducted on samples identified by infrared imaging as having high concentrations of gas hydrate in recovered core samples. These analyses will be used to study porous-media effects and geologic controls on the occurrence of gas hydrate in situ.

Modeling Greenhouse Gas Energy Technology Responses to Climate Change  

Science Conference Proceedings (OSTI)

Models of the global energy system can help shed light on the competition and complementarities among technologies and energy systems both in the presence and absence of actions to affect the concentration of greenhouse gases. This paper explores the role of modeling in the analysis of technology deployment in addressing climate change. It examines the competition among technologies in a variety of markets, and explores conditions under which new markets, such as for hydrogen and carbon disposal, or modern commercial biomass, could emerge. Carbon capture and disposal technologies are shown have the potential to play a central role in controlling the cost of stabilizing the concentration of greenhouse gases, the goal of the UN Framework Convention on Climate Change.

Gas Hydrate Research and Stratigraphic Test Results, Milne Point Unit, Alaska North Slope Gas Hydrate Research and Stratigraphic Test Results, Milne Point Unit, Alaska North Slope Gas Hydrate Research and Stratigraphic Test Results, Milne Point Unit, Alaska North Slope Authors: Robert Hunter (ASRC Energy), Scott Digert (BPXA), Tim Collett (USGS), Ray Boswell (USDOE) Venue: AAPG National Meeting Gas Hydrate session, Oral Presentation, San Antonio, TX, April 22, 2008 (http://www.AAPG.org [external site]) Abstract: This BP-DOE collaborative research project is helping determine whether or not gas hydrate can become a technically and economically recoverable gas resource. Reservoir characterization, development modeling, and associated studies indicate that 0-0.34 trillion cubic meters (TCM) gas may be technically recoverable from the estimated 0.92 TCM gas-in-place within the Eileen gas hydrate accumulation on the Alaska North Slope (ANS). Reservoir modeling indicates sufficient potential for technical recovery to justify proceeding into field operations to acquire basic reservoir and fluid data from the Mount Elbert gas hydrate prospect in the Milne Point Unit (MPU). Successful drilling and data acquisition in the Mount Elbert-01 stratigraphic test well was completed during February 3-19, 2007. Data was acquired from 131 meters of core (30.5 meters gas hydrate-bearing), extensive wireline logging, and wireline production testing operations using Modular Dynamics Testing (MDT). The stratigraphic test validated the 3D seismic interpretation of the MPU gas hydrate-bearing Mount Elbert prospect. Onsite core sub- sampling preserved samples for later analyses of interstitial water geochemistry, physical properties, thermal properties, organic geochemistry, petrophysics, and mechanical properties. MDT testing was accomplished within two gas hydrate-bearing intervals, and acquired during four long shut-in period tests. Four gas samples and one pre-gas hydrate dissociation formation water sample were collected. MDT analyses are helping to improve understanding of gas hydrate dissociation, gas production, formation cooling, and long-term production potential as well as help calibrate reservoir simulation models.

Safety research plan for gas-supply technologies. Final report, March 1982-February 1983  

SciTech Connect

The objective of this study was to develop a multiyear research plan addressing the safety issues of the following gas supply technologies: conventional natural gas, including deep and sour gas wells; unconventional natural gas (Devonian shale, tight gas sands, coalbed methane, and geopressured methane); SNG from coal (surface and in situ), and SNG from biomass. A total of 51 safety issues were identified in the initial review. These safety issues were screened to eliminate those hazards which appeared to be relatively insignificant in terms of accident severity or frequency, or because the potential for resolving the problem through research was considered very low. Twenty-six remaining safety issues were prioritized, and of these, 9 were selected as priority research projects: two under conventional gas; one under unconventional natural gas; and six under SNG from coal. No safety research issues in the biomass area appear to warrant priority consideration.

Venue: AGU Fall Meeting, San Francisco, CA, December 15-19 2008 -- Session OS25: Methane Flux from Naturally Occurring Marine Gas Hydrates http://www.agu.org Abstract: The recently funded DOE/NETL study "HyFlux: Remote sensing and sea-truth measurements of methane flux to the atmosphere" (see MacDonald et al.: HyFlux - Part I) will combine sea surface, water column and shallow subsurface observations to improve our estimates of methane flux from submarine seeps and associated gas hydrate deposits to the water column and atmosphere along the Gulf of Mexico continental margin and other selected areas world-wide. As methane-rich fluids rise towards the sediment-water interface, they will interact with sulfate-rich pore fluids derived from overlying bottom water, which results in the formation of an important biogeochemical redox boundary, the so-called sulfate-methane interface, or SMI. Both methane and sulfate are consumed within the SMI and dissolved inorganic carbon, mostly bicarbonate (HCO3-) and hydrogen sulfide are produced, stimulating authigenic carbonate precipitation at and immediately below the SMI. Accordingly, the formation of authigenic carbonates in methane- and gas-hydrate-rich sediments will sequester a portion of the methane-derived carbon. To date, however, little is known about the quantitative aspects of these reactions. Rates of DIC production are not well constrained, but recent biogeochemical models indicate that CaCO3 precipitation rates may be as high as 120 µmol cm-2a-1. Therefore, AOM-driven carbonate precipitation must be considered when assessing the impact of gas-hydrate-derived methane on the global carbon cycle.

Simulation of the system behavior of hydrate-bearing geologic media involves solving fully coupled mass and heat balance equations. The models need to simulate equilibrium or kinetic processes of hydrate formation and dissociation. TOUGH+HYDRATE is a widely used code for gas hydrate simulations. The code can model non-isothermal gas release, phase changes and flow of fluids and heat. It accounts for up to four mass components and four possible phases. Because hydrate simulations require intensive computational effort, many studies that involve serial processors are limited by problems of complexity and scale. With the growing availability of multi-core CPUs, Linux clusters, and super-computers, the use of parallel processing methods is a distinct advantage. This study develops a domain decomposition approach for large-scale gas hydrate simulations using parallel computation. The approach partitions the simulation domain into small sub-domains. The full simulation domain is simulated integrally by using multiple processes. Each process will be in charge of one portion of the simulation domain for updating thermophysical properties, assembling mass and energy balance equations, solving linear equation systems, and performing other local computations. The linear equation systems are solved in parallel by multiple processes with a parallel linear solver. The multiple processes are run in parallel on shared- or distributed memory multiple-CPU computers. A hybrid approach, running multiple processes in each CPU and using multiple CPUs, may achieve additional speedup. During calculations, communication between processes is needed to update sub-domain boundary parameters. An efficient inter-process communication scheme has been developed. The new approach was implemented into the TOUGH+HYDRATE code and demonstrates excellent speedup and very good scalability. For many large-scale problems, this method can obtain linear or super-linear speedup. This paper will show applications of the new approach to simulate three dimensional field-scale models for gas production from gas-hydrate

The geomechanical response of Hydrate-Bearing Sediments (HBS) is a serious concern that needs to be addressed before the installation of facilities for hydrate deposits can proceed, and if gas production from hydrate deposits is to become reality. HBS are often unconsolidated, and are characterized by low shear strength. Heat from external sources, that cross the formation or depressurization-based production, can induce dissociation of hydrates (a strong cementing agent), and degradation of the structural stability of the HBS. Changes in pressure and temperature, phase changes, and the evolution of an expanding (and structurally weak) gas zone can significantly alter the distribution of loads in the sediments. The corresponding changes in the local stress and strain fields can result in substantial changes in the hydrologic, thermal and geomechanical properties of the system, displacement, and potentially failure.

Geologic Framework of the 2005 Keathley Canyon Geologic Framework of the 2005 Keathley Canyon Gas Hydrate Research Well, Northern Gulf of Mexico Authors: D.R. Hutchinson, P.E. Hart, T.S. Collett, K.M. Edwards, and D.C. Twichell, U.S. Geological Survey, and F. Snyder, WesternGeco-Schlumberger. Venue: American Geophysical UnionÂ’s 2007 Joint Assembly, Acapulco, Mexico, May 22-25, 2007 (http://www.agu.org/meetings/ja07/ [external site]). Abstract: The project was located in the Casey Basin in the northern Gulf of Mexico at 1,335 m water depth. A grid of 2-D high-resolution multichannel seismic lines around the drill sites, targeted for imaging depths down to at least 1,000 m subbottom, reveals multiple disconformities that bound seven mappable seismic stratigraphic units. A major disconformity in the middle of the units stands out for its angular baselapping geometry. From the seismic and drilling data, three episodes of sedimentary deposition and deformation are inferred. The oldest episode consists of fine-grained muds deposited during a period of relative stability in the basin (Units E, F, and G). A second episode (Units C and D) consists of large vertical displacements associated with infilling and ponding of sediment. This second interval corresponds with intercalated fine and coarse-grained material in the drill hole, which sampled the thin edges of much thicker units. The final episode (Units A and B) occurred during much-subdued vertical displacement. Hemipelagic drape (Unit A) characterizes the modern seafloor deposits. The basin is mostly filled. Its sill is part of a subsiding graben that is only 10-20 m shallower than the deepest point in the basin, indicating that gravity-driven transport would mostly bypass the basin. Contemporary faulting along the basin margins has selectively reactivated an older group of faults. The intercalated sand and mud deposits of Units C and D are tentatively correlated with late Pleistocene deposition derived from the western shelf-edge delta/depocenter of the Mississippi River, which was probably most active from 320 ka to 70 ka (Winker and Booth, 2000). Gas hydrate occurs within near-vertical fractures in Units E and F of the oldest episode. The presence of sand within the gas hydrate stability zone is not sufficient to concentrate gas hydrate, even though dispersed gas hydrate occurs deeper in the fractured mud/clay-rich sections of Units E and F.

A Grain-Scale Coupled Model of Multiphase Fluid Flow and Sediment Mechanics A Grain-Scale Coupled Model of Multiphase Fluid Flow and Sediment Mechanics A Grain-Scale Coupled Model of Multiphase Fluid Flow and Sediment Mechanics – Application to Methane Hydrates in Natural Systems Authors: Antone K. Jain and Ruben Juanes Venue: American Geophysical Union Fall Meeting, San Francisco, CA, December 15-19, 2008 – Special Session H06: Particle Tracking Simulation of Fluid Flow and Mass Transport. http://www.agu.org/meetings/fm08/ Abstract: A discrete element model is presented for the simulation, at the grain scale, of gas migration in brine-saturated deformable media. The model rigorously accounts for the presence of two fluids in the pore space by incorporating grain forces due to pore fluid pressures, and surface tension between fluids. The coupled model permits investigating an essential process that takes place at the base of the hydrate stability zone: the upward migration of methane in its own free gas phase. The ways in which gas migration may take place were elucidated: (1) by capillary invasion in a rigid-like medium; and (2) by initiation and propagation of a fracture. Results indicate that the main factor controlling the mode of gas transport in the sediment is the grain size, and that coarse-grain sediments favor capillary invasion, whereas fracturing dominates in fine-grain media. The results have important implications for understanding hydrates in natural systems. The results predict that, in fine sediments, hydrate will likely form in veins that follow a fracture-network pattern, and the hydrate concentration in this type of accumulations will likely be quite low. In coarse sediments, the buoyant methane gas is likely to invade the pore space more uniformly, in a process akin to invasion percolation, and the overall pore occupancy is likely to be much higher than for a fracture-dominated regime. These implications are consistent with field observations of methane hydrates in natural

Long-range assessment of R and D policy for gas-related conversion technologies and unconventional natural gas resources  

Science Conference Proceedings (OSTI)

This study analyzes the energy impacts on the US energy-economy system on a set of successful R and D programs. These programs are presumed to have led to the commercialization of innovative technologies that increase the US gaseous fuels resource base and promote the development of advanced natural gas conversion technologies for residential/commercial uses. The GRI and its principal subcontractor, TRW Incorporated, provided the detailed specifications of the energy conditions for both a Base Case and an R and D Policy Case. These conditions can be broadly categorized in terms of key energy resource price assumptions, energy resource availabilities, technology characterizations and market penetration guidelines for all energy technologies. Dale W. Jorgenson Associates (DJA) developed a set of demographic and economic projections including population, employment, and real GNP growth rates. The GRI and TRW staff provided the technology characterizations for most of the gas-related technologies and a number of other technologies. The data for the remaining technology characterizations were taken, for the most part, from Bhagat et al. This report presents the energy results from the BNL/DJA energy-economy system as executed under GRI specifications. It is intended to serve as a complement to the DJA report on the macro-economic consequences of these specifications. Certain assumption incorporated in the R and D and Base scenarios relating to market penetration were identified as particularly sensitive. In light of the uncertainty inherent in them, an additional set of sensitivity runs were requested by GRI and are presented in Appendix B.

Baker (DOE) Venue: American Chemical Society Meeting, March 22-26, 2009, Salt Lake City, Utah http://portal.acs.org/portal/acs/corg/content?_nfpb=true&_pageLabel=PP_MEETINGS&node_id=86&use_sec=false&__uuid=614acbfd-ce1c-4a0b-98de-348a14738f4e [external site] Abstract: In 1982, scientists onboard the Research Vessel Glomar Challenger retrieved a meter-long sample of massive gas hydrate off the coast of Guatemala. This sample became the impetus for the first United States national research and development program dedicated to gas hydrates. By the mid 1990s, it was widely accepted that gas hydrates represented a vast storehouse of gas. Recognizing the importance of gas hydrate research and the need for coordinated efforts, Congress and the President of the United States enacted Public Law 106-193, the Methane Hydrate Research and Development Act of 2000. Authorization for this program was extended to 2010 as part of the Energy Policy Act of 2005. Many of the current gas hydrate projects in the United States are conducted within this program, which is administered by the U. S. Department of Energy in collaboration with six other U.S. federal agencies, and conducted in partnership with private industry, academic institutions, and DOEÂ’s National Laboratories. In addition, other U.S. federal agencies conduct significant self-directed gas hydrate research; most notably the gas hydrate resource assessment activities conducted by U.S. Department of Interior agencies (the U.S. Geological Survey and the Minerals Management Service).

TECHNOLOGIES TO ENHANCE THE OPERATION OF EXISTING NATURAL GAS COMPRESSION INFRASTRUCTURE  

SciTech Connect

This project has documented and demonstrated the feasibility of technologies and operational choices for companies who operate the large installed fleet of integral engine compressors in pipeline service. Continued operations of this fleet is required to meet the projected growth of the U.S. gas market. Applying project results will meet the goals of the DOE-NETL Natural Gas Infrastructure program to enhance integrity, extend life, improve efficiency, and increase capacity, while managing NOx emissions. These benefits will translate into lower cost, more reliable gas transmission, and options for increasing deliverability from the existing infrastructure on high demand days. The power cylinders on large bore slow-speed integral engine/compressors do not in general combust equally. Variations in cylinder pressure between power cylinders occur cycle-to-cycle. These variations affect both individual cylinder performance and unit average performance. The magnitude of the variations in power cylinder combustion is dependent on a variety of parameters, including air/fuel ratio. Large variations in cylinder performance and peak firing pressure can lead to detonation and misfires, both of which can be damaging to the unit. Reducing the variation in combustion pressure, and moving the high and low performing cylinders closer to the mean is the goal of engine balancing. The benefit of improving the state of the engine ''balance'' is a small reduction in heat rate and a significant reduction in both crankshaft strain and emissions. A new method invented during the course of this project is combustion pressure ratio (CPR) balancing. This method is more effective than current methods because it naturally accounts for differences in compression pressure, which results from cylinder-to-cylinder differences in the amount of air flowing through the inlet ports and trapped at port closure. It also helps avoid compensation for low compression pressure by the addition of excess fuel to achieve equalizing peak firing pressure, even if some of the compression pressure differences are attributed to differences in cylinder and piston geometry, clearance, and kinematics. The combination of high-pressure fuel injection and turbocharging should produce better mixing of fuel and air in lean mixtures. Test results documented modest improvements in heat rate and efficiency and significant improvements in emissions. The feasibility of a closed-loop control of waste-gate setting, which will maintain an equivalence ratio set point, has been demonstrated. This capability allows more direct tuning to enhance combustion stability, heat rate, or emissions. The project has documented the strong dependence of heat rate on load. The feasibility of directly measuring power and torque using the GMRC Rod Load Monitor (RLM) has been demonstrated. This capability helps to optimize heat rate while avoiding overload. The crankshaft Strain Data Capture Module (SDCM) has shown the sensitivity to changes in operating conditions and how they influence crankshaft bending strain. The results indicate that: balancing reduces the frequency of high-strain excursions, advanced timing directly increases crankshaft dynamic strain, reduced speed directly reduces strain, and high-pressure fuel injection reduces crankshaft strain slightly. The project demonstrated that when the timing is advanced, the heat rate is reduced, and when the timing is retarded, the heat rate is increased. One reason why timing is not advanced as much as it might be is the potential for detonation on hot days. A low-cost knock detector was demonstrated that allowed active control to use timing to allow the heat rate benefit to be realized safely. High flow resistance losses in the pulsation control systems installed on some compressors have been shown to hurt efficiency of both compressor and engine/compressor system. Improved pulsation control systems have the potential to recover almost 10% of available engine power. Integrity enhancements and reduced component failure probability will enhance aggregate

Conditions under Which Gaseous Methane Will Fracture Ocean Sediments and Penetrate Through the Hydrate Stability Zone Conditions under Which Gaseous Methane Will Fracture Ocean Sediments and Penetrate Through the Hydrate Stability Zone Conditions under Which Gaseous Methane Will Fracture Ocean Sediments and Penetrate Through the Hydrate Stability Zone: Modeling Multiphase Flow and Sediment Mechanics at the Pore-Scale Authors: Antone K. Jain and Ruben Juanes Venue: American Geophysical Union Fall Meeting, San Francisco, CA, December 15-19, 2008 – Special Session H06: Particle Tracking Simulation of Fluid Flow and Mass Transport. http://www.agu.org/meetings/fm08/ Abstract: Two competing processes were simulated, capillary invasion and fracture opening, by which free methane gas penetrates the Hydrate Stability Zone (HSZ). In situ conditions were predicted in which the methane propagates fractures and flows all the way through the HSZ and into the ocean, bypassing hydrate formation. In the fully coupled model, the discrete element method was used to simulate the sediment mechanics, and pore fluid pressures and surface tension between the gas and brine were accounted for by incorporating additional sets of pressure forces and adhesion forces. Results indicate that given enough capillary pressure, the main factor controlling the mode of gas transport is the grain size, and show that coarse-grain sediments favor capillary invasion and widespread hydrate formation, whereas fracturing dominates in fine-grain sediments. The fracturing threshold was calculated as a function of grain size, capillary pressure, and seafloor depth, and place these results in the context of naturally-occurring hydrate

Capillarity-controlled displacements in sediments with moveable grains Capillarity-controlled displacements in sediments with moveable grains Capillarity-controlled displacements in sediments with moveable grains: Implications for growth of methane hydrates Authors: Maša Prodanovic (speaker), Steven L. Bryant Venue: SPE Annual Technical Conference and Exhibition, Denver, Colorado, 21-24 September, 2008. http://www.spe.org [external site]. Abstract: We consider immiscible displacements when fluid/fluid interfaces are controlled by capillary forces. The progressive quasistatic (PQS) algorithm based on the level set method readily determines the geometry of these interfaces at the pore level. Capillary pressure generally exerts a net force on grains supporting an interface. We extend PQS to implement a kinematic model of grain displacement in response to that force. We examine the changes in the drainage curve caused by this coupling. We compute the interfacial area associated with the bulk water phase, anticipating preferential growth of methane hydrate there. Gas invasion of sediments is one mechanism by which methane hydrates are believed to form. In unconsolidated ocean sediments the capillary pressure exerted by an accumulated gas phase below the hydrate stability zone can be large enough to move grains apart. This motion alters the pore throat sizes which control subsequent drainage of the sediment. A model for the dynamics of this process is useful for assessing the competition between drainage (controlled by capillary forces) and fracturing (controlled by pore pressure and earth stresses). This in turn provides insight into the possible growth habits within the hydrate stability zone. When grains can move in response to net force exerted by the gas phase, small variations in an otherwise uniform distribution of pore throat sizes quickly lead to self-reinforcing, focused channels of gas phase. In contrast to behavior in stationary grains, the drainage curve exhibits no clear percolation threshold. Displacements in materials with broad throat size distributions also exhibit self-reinforcing channels. Behind the leading edge of the displacement front, the net force exerted on the grains tends to push them together. This effectively seals off these regions from subsequent invasion. Thus hydrate growth tends to be localized along the channel of displaced grains. This is the first quantitative grain-scale study of the drainage behavior when grains can move in response to invasion events. The coupling leads to qualitatively different displacement patterns. The method presented for studying this behavior is applicable to any granular material and to other applications, such as sand production.

De-Watering of Hunton Reservoirs De-Watering of Hunton Reservoirs De-Watering of Hunton Reservoirs Author: Mohan Kelkar, University of Tulsa, Tulsa, OK. Venue: Tulsa Association of Petroleum Landmen meeting in Tulsa, OK, April 19, 2007 (http://www.landman.org [external site]). Abstract: The Hunton reservoir in Oklahoma represents one of the largest discoveries in Oklahoma in recent history. Since 1995, several Hunton reservoir fields have been exploited by various operators. The principle behind this exploitation remains the same: The wells produce large quantities of water, and along with it, significant quantities of natural gas and sometimes oil. Examination of various fields producing from the Hunton reservoir indicates that the economic success from these fields is not uniform. Some fields produce significant quantities of oil, whereas some fields only produce gas. In some fields, horizontal wells work best, whereas in some other fields, vertical wells do a good job. The water production from the fields ranges from as low as few hundred barrels per day to several thousand barrels per day. In this paper, we present the results from various fields to indicate the parameters needed in a Hunton field to make it economically successful. We restrict our evaluation to parameters that can be easily measured or are readily available. These include log data (gamma ray, resistivity, neutron, and density), initial potential data, production data (oil, gas, and water—if available) and well configuration (vertical or horizontal). By analyzing the recovery of oil and gas according to various reservoir parameters, we developed a methodology for predicting the future success of the field. For example, a clear relationship exists between porosity of the rock and initial hydrocarbon saturation: The higher the oil saturation, the better the recovery factor. Initial potential is critical in determining possible recovery. Horizontal wells cost 1.5 to 2 times more than vertical wells and may not provide the additional recovery to justify the costs. The Hunton formation is extensive in Oklahoma. If we want to extend the success of some of the fields to other areas, we need clear guidelines in terms of what is needed to exploit those fields. This paper provides some of those guidelines based on the examination of the currently producing fields.

Morrow, Snuller Price, and Margaret S. Torn Journal Science Volume 335 Start Page 53 Issue 6064 Pagination 53-59 Date Published 01/2012 Abstract Several states and countries have adopted targets for deep reductions in greenhouse gas emissions by 2050, but there has been little physically realistic modeling of the energy and economic transformations required. We analyzed the infrastructure and technology path required to meet California's goal of an 80% reduction below 1990 levels, using detailed modeling of infrastructure stocks, resource constraints, and electricity system operability. We found that technically feasible levels of energy efficiency and decarbonized energy supply alone are not sufficient; widespread electrification of transportation and other sectors is required. Decarbonized electricity would become the dominant form of energy supply, posing challenges and opportunities for economic growth and climate policy. This transformation demands technologies that are not yet commercialized, as well as coordination of investment, technology development, and infrastructure deployment.

Fluid Flow through Heterogeneous Methane-Hydrate Bearing Sand Fluid Flow through Heterogeneous Methane-Hydrate Bearing Sand Fluid Flow through Heterogeneous Methane-Hydrate Bearing Sand: Observations Using X-Ray CT Scanning Authors: Yongkoo Seol and Timothy J. Kneafsey Venue: 6th International Conference on Gas Hydrates (ICGH 2008), Vancouver, British Columbia, CANADA, July 6-10, 2008. http://www.icgh.org/ [external site] Abstract: The effects of porous medium heterogeneity on methane hydrate formation, water flow through the heterogeneous hydrate-bearing sand, and hydrate dissociation were observed in an experiment using a heterogeneous sand column with prescribed heterogeneities. X-ray computed tomography (CT) was used to monitor saturation changes in water, gas, and hydrate during hydrate formation, water flow, and hydrate dissociation. The sand column was packed in several segments having vertical and horizontal layers with two distinct grain-size sands. The CT images showed that as hydrate formed, the water and hydrate saturations were dynamically redistributed by variations in capillary strength of the medium (the tendency for a material to imbibe water), which changed with the presence and saturation of hydrate. Water preferentially flowed through fine sand near higher hydrate-saturation regions where the capillary strength was elevated relative to the lower hydrate saturation regions. Hydrate dissociation initiated by depressurization varied with different grain sizes and hydrate saturations.

Saline Water Disposal in the Uinta Basin, Utah Saline Water Disposal in the Uinta Basin, Utah Saline Water Disposal in the Uinta Basin, Utah Authors: Michael D. Vanden Berg, Stephanie Carney, Michael D. Laine, Craig D. Morgan, Utah Geological Survey; and Paul B. Anderson, consulting geologist. Venue: Poster Session: Responsible Development, Sustainability, and Climate Science—Groundwater and Site Remediation, June 9, 2009, American Association of Petroleum Geologists annual meeting, Denver, CO, June 7 to 10, 2009. http://www.aapg.org/denver/ [external site] Abstract: Saline water disposal is the single most pressing issue with regard to increasing petroleum and natural gas production in the Uinta Basin of Utah. Conventional oil and gas fields in the basin provide 67% of Utah’s total crude oil production and 71% of Utah’s total natural gas, the latter of which has increased 175% in the last 10 years. As petroleum production increases, so does saline water production, creating an increased need for economic and environmentally responsible disposal plans. Current water disposal wells are near capacity, and permitting for new wells is being delayed because of a lack of technical data regarding potential disposal aquifers and questions concerning contamination of fresh water sources. Many Uinta Basin operators claim that petroleum and natural gas production cannot reach its full potential until a suitable, long-term saline water disposal solution is determined. Researchers have begun efforts to re-map the base of the moderately saline aquifer within the Uinta Basin using more robust data and more sophisticated GIS techniques than previous efforts. Below this base, they believe that saline water can be injected without damage to the overlying freshwater reservoirs. Water chemistry data are being collected from wells of operators and governmental agencies. These ground-truth data are supplemented with water chemistry information calculated from geophysical logs. In addition to the new GIS-based map, the researchers are constructing cross sections showing the stratigraphic position of the moderately saline to very saline transition and its relationship to potential seals and disposal zones in the Uinta Basin. A potentially suitable disposal zone for large volume saline water disposal is the fresh to slightly saline Bird’s-Nest aquifer. This aquifer is located in the oil shale zone of the Green River formation’s Parachute Creek member and is 200 to 300 ft above the kerogen-rich Mahogany zone. A significant concern is that saline water disposal into the Bird’s-Nest by conventional gas producers may hinder oil shale development by creating unforeseen economic and technical hurdles. With increased saline water disposal, the water quality in the Bird’s-Nest could degrade and create additional water disposal problems for oil shale development companies. Researchers have examined this aquifer in outcrop, core, and geophysical logs and have gained a better understanding of its areal extent, thickness, and zones of differing water chemistry

NEW AND NOVEL FRACTURE STIMULATION TECHNOLOGIES FOR THE REVITALIZATION OF EXISTING GAS STORAGE WELLS  

SciTech Connect

Gas storage wells are prone to continued deliverability loss at a reported average rate of 5% per annum (in the U.S.). This is a result of formation damage due to the introduction of foreign materials during gas injection, scale deposition and/or fines mobilization during gas withdrawal, and even the formation and growth of bacteria. As a means to bypass this damage and sustain/enhance well deliverability, several new and novel fracture stimulation technologies were tested in gas storage fields across the U.S. as part of a joint U.S. Department of Energy and Gas Research Institute R&D program. These new technologies include tip-screenout fracturing, hydraulic fracturing with liquid CO{sub 2} and proppant, extreme overbalance fracturing, and high-energy gas fracturing. Each of these technologies in some way address concerns with fracturing on the part of gas storage operators, such as fracture height growth, high permeability formations, and fluid sensitivity. Given the historical operator concerns over hydraulic fracturing in gas storage wells, plus the many other unique characteristics and resulting stimulation requirements of gas storage reservoirs (which are described later), the specific objective of this project was to identify new and novel fracture stimulation technologies that directly address these concerns and requirements, and to demonstrate/test their potential application in gas storage wells in various reservoir settings across the country. To compare these new methods to current industry deliverability enhancement norms in a consistent manner, their application was evaluated on a cost per unit of added deliverability basis, using typical non-fracturing well remediation methods as the benchmark and considering both short-term and long-term deliverability enhancement results. Based on the success (or lack thereof) of the various fracture stimulation technologies investigated, guidelines for their application, design and implementation have been developed. A final research objective was to effectively deploy the knowledge and experience gained from the project to the gas storage industry at-large.

The Petroleum Technology Transfer Council (PTTC) continued pursuing its mission of helping U.S. independent oil and natural gas producers make timely, informed technology decisions. Networking opportunities that occur with a Houston Headquarters (HQ) location are increasing name awareness. Focused efforts by Executive Director Don Duttlinger to interact with large independents, national service companies and some majors are continuing to supplement the support base of the medium to smaller industry participants around the country. PTTC is now involved in many of the technology-related activities that occur in high oil and natural gas activity areas. Access to technology remains the driving force for those who do not have in-house research and development capabilities and look to the PTTC to provide services and options for increased efficiency.

Oil and gas technology transfer activities and potential in eight major producing states. Volume 1  

Science Conference Proceedings (OSTI)

In 1990, the Interstate Oil and Gas Compact Commission (the Compact) performed a study that identified the structure and deficiencies of the system by which oil and gas producers receive information about the potential of new technologies and communicate their problems and technology needs back to the research community. The conclusions of that work were that major integrated companies have significantly more and better sources of technology information than independent producers. The majors also have significantly better mechanisms for communicating problems to the research and development (R&D) community. As a consequence, the Compact recommended analyzing potential mechanisms to improve technology transfer channels for independents and to accelerate independents acceptance and use of existing and emerging technologies. Building on this work, the Compact, with a grant from the US Department Energy, has reviewed specific technology transfer organizations in each of eight major oil producing states to identify specific R&D and technology transfer organizations, characterize their existing activities, and identify potential future activities that could be performed to enhance technology transfer to oil and gas producers. The profiles were developed based on information received from organizations,follow-up interviews, site visit and conversations, and participation in their sponsored technology transfer activities. The results of this effort are reported in this volume. In addition, the Compact has also developed a framework for the development of evaluation methodologies to determine the effectiveness of technology transfer programs in performing their intended functions and in achieving desired impacts impacts in the producing community. The results of that work are provided in a separate volume.

Economic benefits of R and D on gas supply technologies. [Unconventioal natural gas resources which are tight sands, Devonian shale, coal seam gas, and gas co-produced with water  

SciTech Connect

Advanced natural gas supply technologies, if successful, could lower the average cost of gas to consumers by 18% and increase the expected gas demand by 2 quads/year by the year 2000. Advanced production techniques for unconventional gas will have by far the greatest impact on future gas prices, providing economic benefits of between $200 billion and $320 billion. Advanced SNG from coal will provide only a $9 billion benefit if unconventional gas meets all of its performance targets. However, higher demand and failure of unconventional gas R and D could raise the benefits of SNG research to $107 billion. SNG research provides a hedge value that increases the likelihood of receiving a positive payoff from gas supply R and D. Changing the performance goals for SNG research to emphasize cost reduction rather than acceleration of the date of commercialization would greatly increase the potential benefits of the program. 9 references, 8 figures, 5 tables.

A fuel cycle framework for evaluating greenhouse gas emission reduction technology  

SciTech Connect

Energy-related greenhouse gas (GHG) emissions arise from a number of fossil fuels, processes and equipment types throughout the full cycle from primary fuel production to end-use. Many technology alternatives are available for reducing emissions based on efficiency improvements, fuel switching to low-emission fuels, GHG removal, and changes in end-use demand. To conduct systematic analysis of how new technologies can be used to alter current emission levels, a conceptual framework helps develop a comprehensive picture of both the primary and secondary impacts of a new technology. This paper describes a broad generic fuel cycle framework which is useful for this purpose. The framework is used for cataloging emission source technologies and for evaluating technology solutions to reduce GHG emissions. It is important to evaluate fuel mix tradeoffs when investigating various technology strategies for emission reductions. For instance, while substituting natural gas for coal or oil in end-use applications to reduce CO{sub 2} emissions, natural gas emissions of methane in the production phase of the fuel cycle may increase. Example uses of the framework are given.

Enabling Technology for Monitoring & Predicting Gas Turbine Health & Performance in COAL IGCC Powerplants  

SciTech Connect

The ''Enabling & Information Technology To Increase RAM for Advanced Powerplants'' program, by DOE request, has been re-directed, de-scoped to two tasks, shortened to a 2-year period of performance, and refocused to develop, validate and accelerate the commercial use of enabling materials technologies and sensors for Coal IGCC powerplants. The new program has been re-titled as ''Enabling Technology for Monitoring & Predicting Gas Turbine Health & Performance in IGCC Powerplants'' to better match the new scope. This technical progress report summarizes the work accomplished in the reporting period April 1, 2004 to August 31, 2004 on the revised Re-Directed and De-Scoped program activity. The program Tasks are: Task 1--IGCC Environmental Impact on high Temperature Materials: This first materials task has been refocused to address Coal IGCC environmental impacts on high temperature materials use in gas turbines and remains in the program. This task will screen material performance and quantify the effects of high temperature erosion and corrosion of hot gas path materials in Coal IGCC applications. The materials of interest will include those in current service as well as advanced, high-performance alloys and coatings. Task 2--Material In-Service Health Monitoring: This second task develops and demonstrates new sensor technologies to determine the in-service health of advanced technology Coal IGCC powerplants, and remains in the program with a reduced scope. Its focus is now on only two critical sensor need areas for advanced Coal IGCC gas turbines: (1) Fuel Quality Sensor for detection of fuel impurities that could lead to rapid component degradation, and a Fuel Heating Value Sensor to rapidly determine the fuel heating value for more precise control of the gas turbine, and (2) Infra-Red Pyrometer to continuously measure the temperature of gas turbine buckets, nozzles, and combustor hardware.

Super-Cement for Annular Seal & Long-Term Integrity in Deep, Hot Wells Super-Cement for Annular Seal & Long-Term Integrity in Deep, Hot Wells Super-Cement for Annular Seal & Long-Term Integrity in Deep, Hot Wells Authors: Fred Sabins, Kevin Edgely, and Larry Watters, CSI Technologies, LLC, Houston, TX. Venue: 2007 Drilling Engineering Association Workshop, Moody Gardens Hotel, Galveston, TX, June 19-20, 2007 (http://www.dea-global.org) [external site]). Abstract: Successful laboratory and field testing of Ultra-Seal® R and Pre-Stressed Cement will be presented. The application of these materials can dramatically reduce the costs of re-establishing annular seal integrity in deep, hot wells, thereby significantly lowering life-cycle well costs. CSI Technologies chose two cement types for further field testing in the third phase of the project to develop a “supercement” for work in high-temperature/high-pressure (HT/HP) wells. HT/HP wells often encounter problems with isolation of production zones due to cement failures. This can result in expensive repair jobs and costly shut-ins of high-volume wells. CSI determined that resin and magnesium oxide cements showed very good mechanical properties and bonding characteristics and are controllable at HT/HP conditions. The resin cement has been used successfully in more than 50 field plugging jobs and in one HT/HP squeeze job. CSI developed a second supercement formulation that is Portland cement- based and functions by generating substantial expansion during the curing process. This material functions in the confined wellbore environment by developing significant cement matrix compressive stress during cure, resulting in a compressive pre-load. In practice, the compressive pre-load functions to elevate the effective tensile strength of the material because the compressive stress must be relieved before the material can experience tensile stress. Additionally, the pre-load functions to keep the material tightly bound to the wellbore tubulars, thereby reducing the tendency of repeated stress cycles to form a microannulus.

The ''Enabling & Information Technology To Increase RAM for Advanced Powerplants'' program, by DOE request, was re-directed, de-scoped to two tasks, shortened to a 2-year period of performance, and refocused to develop, validate and accelerate the commercial use of enabling materials technologies and sensors for coal/IGCC powerplants. The new program was re-titled ''Enabling Technology for Monitoring & Predicting Gas Turbine Health & Performance in IGCC Powerplants''. This final report summarizes the work accomplished from March 1, 2003 to March 31, 2004 on the four original tasks, and the work accomplished from April 1, 2004 to July 30, 2005 on the two re-directed tasks. The program Tasks are summarized below: Task 1--IGCC Environmental Impact on high Temperature Materials: The first task was refocused to address IGCC environmental impacts on high temperature materials used in gas turbines. This task screened material performance and quantified the effects of high temperature erosion and corrosion of hot gas path materials in coal/IGCC applications. The materials of interest included those in current service as well as advanced, high-performance alloys and coatings. Task 2--Material In-Service Health Monitoring: The second task was reduced in scope to demonstrate new technologies to determine the inservice health of advanced technology coal/IGCC powerplants. The task focused on two critical sensing needs for advanced coal/IGCC gas turbines: (1) Fuel Quality Sensor to rapidly determine the fuel heating value for more precise control of the gas turbine, and detection of fuel impurities that could lead to rapid component degradation. (2) Infra-Red Pyrometer to continuously measure the temperature of gas turbine buckets, nozzles, and combustor hardware. Task 3--Advanced Methods for Combustion Monitoring and Control: The third task was originally to develop and validate advanced monitoring and control methods for coal/IGCC gas turbine combustion systems. This task was refocused to address pre-mixed combustion phenomenon for IGCC applications. The work effort on this task was shifted to another joint GE Energy/DOE-NETL program investigation, High Hydrogen Pre-mixer Designs, as of April 1, 2004. Task 4--Information Technology (IT) Integration: The fourth task was originally to demonstrate Information Technology (IT) tools for advanced technology coal/IGCC powerplant condition assessment and condition based maintenance. The task focused on development of GateCycle. software to model complete-plant IGCC systems, and the Universal On-Site Monitor (UOSM) to collect and integrate data from multiple condition monitoring applications at a power plant. The work on this task was stopped as of April 1, 2004.

Updated Results from Deep Trek High-Temperature Electronics Development Programs Updated Results from Deep Trek High-Temperature Electronics Development Programs Updated Results from Deep Trek High-Temperature Electronics Development Programs Author: Bruce W. Ohme, Honeywell Inc., Plymouth, MN. Venue: HITEN 2007 (High-Temperature Electronics Network conference), St. Catherine’s College, Oxford, U.K., September 17–19, 2007, (http://science24.com/event/hiten2007 [external site]). Abstract: Electronics are used in modern oil and gas exploration to collect, log, and/or process data such as heading and inclination, weight on the bit, vibration, seismic/acoustic response, temperature, pressure, radiation, and resistivity of the strata. High-temperature electronics are needed that can operate reliably in deep-well conditions (up to 250oC). Under its Deep Trek program, the U.S. Department of Energy has funded two projects led by Honeywell. The first project, launched in 2003 and being completed this year, established a production-level integrated circuit manufacturing process, components, and design tools specifically targeting high-temperature environments (up to 250oC). The second project, launched in 2006 and expected to be completed in 2008, will develop rugged packaging suitable for downhole shock and vibration levels that will be used to house and demonstrate components developed in the earlier project. This paper will describe updated results from both of these projects, including previously unreported results obtained from prototype testing of a high-resolution analog-to-digital converter (ADC); a high-temperature, single-poly, floating-gate EEPROM (electrically erasable programmable read-only memory); and a 12-bit, successive-approximation ADC. Also, a multi-chip module being developed as a complete downhole processing unit will be discussed

Estimating Fracture Reorientation Due to Fluid Injection/Production Estimating Fracture Reorientation Due to Fluid Injection/Production Estimating Fracture Reorientation Due to Fluid Injection/Production Authors: Zongyu Zhai and Mukul M. Sharma, University of Texas at Austin. Venue: Society of Petroleum Engineers’ Production and Operations Symposium, Oklahoma City, OK, April 1–3, 2007 (http://www.spe.org/ [external site]). Abstract: The injection or production of large volumes of fluid into or from a reservoir can result in significant changes to the effective in-situ stress distributions. Field evidence of this has been provided in the past by mapping refracturing treatments in tight gas sands and microseismic monitoring of injection wells in waterflooded reservoirs. A poro-elastic model is presented to show how the extent of fracture reorientation can be estimated under different conditions of fluid injection and production. The extent of fracture reorientation is a function of the in-situ stresses, the mechanical properties of the rock, and the pore pressure gradients. In reservoirs where the pore pressure gradients are complicated due to multiple injection and production wells, fracture reorientation is sensitive to the net pore-pressure gradients. Fractures tend to reorient themselves towards the injection wells and away from production wells, if the pressure gradients are comparable to the in-situ stress contrast. While far-field principal stress orientations are impacted only by in-situ stresses and pore-pressure gradients, near-wellbore in-situ stress orientation is also impacted by the hoop stress and the wellbore pressure. These can have a significant effect on near-wellbore fracture reorientation. The results of our model are compared with field observations obtained from microseismic monitoring of water injection wells. The implications of the results to refracturing operations and candidate well selection are discussed.

Drilling Tests of an Active Vibration Damper Drilling Tests of an Active Vibration Damper Drilling Tests of an Active Vibration Damper Authors: Mark Wassell, Martin Cobern, Carl Perry, Jason Barbely, and Daniel Burgess, APS Technology, Inc. Venue: Drilling Engineering Association’s 2007 DEA Workshop in Galveston, TX, June 19-20, 2007 Abstract: Testing of an active drilling vibration damper (AVD) system at TerraTek Laboratory, under conditions designed to induce vibration, demonstrated that the use of the AVD reduced vibration, maintained more consistent weight-on-bit, and increased rate of penetration (ROP). These tests demonstrated that the AVD is likely to provide significant time and cost savings, particularly in deep wells. The results of these tests will be outlined. Related NETL Project: The goal of the related NETL project DE-FC26-02NT41664, “Drilling Vibration Monitoring and Control System,” is to improve ROP and reduce the incidence of premature equipment failures in deep hard rock drilling environments by reducing harmful drillstring vibration.

Assessment of basic research needs for greenhouse gas control technologies  

SciTech Connect

This paper is an outgrowth of an effort undertaken by the Department of Energy's Office of Energy Research to assess the fundamental research needs to support a national program in carbon management. Five topics were identified as areas where carbon management strategies and technologies might be developed: (1) capture of carbon dioxide, decarbonization strategies, and carbon dioxide disposal and utilization; (2) hydrogen development and fuel cells; (3) enhancement of the natural carbon cycle; (4) biomass production and utilization; and (5) improvement of the efficiency of energy production, conversion, and utilization. Within each of these general areas, experts came together to identify targets of opportunity for fundamental research likely to lead to the development of mid- to long-term solutions for stabilizing or decreasing carbon dioxide and other greenhouse gases in the atmosphere. Basic research to support the options outlined above are far reaching-from understanding natural global processes such as the ocean and terrestrial carbon cycles to development of new materials and concepts for chemical separation. Examples of fundamental research needs are described in this paper.

Fine-Scale Control of Microbial Communities in Deep Marine Sediments Fine-Scale Control of Microbial Communities in Deep Marine Sediments Fine-Scale Control of Microbial Communities in Deep Marine Sediments that Contain Hydrates and High Concentrations of Methane Authors: Colwell, F. (speaker, Oregon State University), Hangsterfer, A., Brodie, E., Daly, R., Holland, M., Briggs, B., Carini, P., Torres, M., Kastner, M., Long, P., Schaef, H., Delwiche, M., Winters, W., and Riedel, M. Venue: American Geophysical Union’s fall meeting in San Francisco, CA, December 10–14, 2007 (http://www.agu.org/meetings/fm07/ [external site]). Abstract: Deep subseafloor sediments with high concentrations of organic carbon and microbially generated methane contain microbial communities that play an important role in the biogeochemical cycling of carbon. However, there remains a limited understanding of the fine (centimeter)-scale sediment properties (e.g., grain size, presence/absence of hydrates) that determine key microbial attributes in deep marine sediments. This project’s objective is to determine the quantity, diversity, and distribution of microbial communities in the context of abiotic properties in gas-rich marine sediments. DNA was extracted from deep marine sediments cored from various continental shelf locations, including offshore India and the Cascadia Margin. Abiotic characterization of the same sediments included grain size analysis, chloride concentrations in sediment pore waters, and presence of hydrates in the sediments as determined by thermal anomalies. As in past studies of such systems, most of the samples yielded low levels of DNA (0.3-1.5 ng/g of sediment). Bacterial DNA appeared to be more easily amplified than archaeal DNA. Initial attempts to amplify DNA using primers specific for the methanogen functional gene, methyl-CoM-reductase, were unsuccessful. Infrequently, cores from relatively shallow sediments (e.g., 0.5 mbsf Leg 204, 1251B-1H) from central (Hydrate Ridge) and northern (offshore Vancouver Island) Cascadia and from India’s eastern margin contained macroscopically visible, pigmented biofilms. One of these biofilms was composed of high concentrations of cell clusters when viewed microscopically. The predominant cells in the Hydrate Ridge biofilm were large (ca. 10 um) cocci, and preliminary characterization of the 16S rDNA amplified and sequenced from this biofilm suggests the prevalence of a microbe with 97% similarity to mycobacteria. These discrete biofilm communities appear to be distinctive relative to the normally sparse distribution of cells in the sediments. By determining how the abiotic properties of deep marine sediments control the numbers and distribution of microbial communities that process organic matter, project researchers hope to provide better parameters for computational models that describe carbon cycling in these systems.

Novel Applications for Biogeophysics: Prospects for Detecting Key Subseafloor Geomicrobiological Processes or Habitats Novel Applications for Biogeophysics: Prospects for Detecting Key Subseafloor Geomicrobiological Processes or Habitats Novel Applications for Biogeophysics: Prospects for Detecting Key Subseafloor Geomicrobiological Processes or Habitats Authors: Rick Colwell, Oregon State University, and Dimitris Ntarlagiannis, Rutgers University. Venue: American Geophysical UnionÂ’s 2007 Joint Assembly, Acapulco Mexico, May 21-25, 2007 (http://www.agu.org/ [external site]). Abstract: The new subdiscipline of biogeophysics has focused mostly on the geophysical signatures of microbial processes in contaminated subsurface environments usually undergoing remediation. However, the use of biogeophysics to examine the biogeochemistry of marine sediments has not yet been well integrated into conceptual models that describe subseafloor processes. Current examples of geophysical measurements that have been used to detect geomicrobiological processes or infer their location in the seafloor include sound surveillance system (SOSUS)-derived data that detect seafloor eruptive events, deep and shallow cross-sectional seismic surveys that determine the presence of hydraulically conductive zones or gas-bearing sediments (e.g., bottom-simulating reflectors or bubble-rich strata), and thermal profiles. One possible area for innovative biogeophysical characterization of the seafloor involves determining the depth of the sulfate-methane interface (SMI) in locations where sulfate diffuses from the seawater and methane emanates from subsurface strata. The SMI demarcates a stratum where microbially driven anaerobic methane oxidation (AMO) is dependent upon methane as an electron donor and sulfate as an electron acceptor. AMO is carried out by a recently defined, unique consortium of microbes that metabolically temper the flux of methane into the overlying seawater. The depth of the SMI is, respectively, shallow or deep according to whether a high or low rate of methane flux occurs from the deep sediments. Presently, the SMI can only be determined by direct measurements of methane and sulfate concentrations in the interstitial waters or by molecular biological techniques that target the microbes responsible for creating the SMI. Both methods require collection and considerable analysis of sediment samples. Therefore, detection of the SMI by non-destructive methods would be advantageous. As a key biogeochemical threshold in marine sediments, the depth of the SMI defines methane charge in marine sediments, whether it is from dissolved methane or from methane hydrates. As such, a biogeophysical strategy for determining SMI depth would represent an important contribution to assessing methane charge with respect to climate change, sediment stability, or potential energy resources.

Technology on In-Situ Gas Generation to Recover Residual Oil Reserves  

Science Conference Proceedings (OSTI)

This final technical report covers the period October 1, 1995 to February 29, 2008. This chapter begins with an overview of the history of Enhanced Oil Recovery techniques and specifically, CO2 flood. Subsequent chapters conform to the manner consistent with the Activities, Tasks, and Sub-tasks of the project as originally provided in Exhibit C1 in the Project Management Plan dated September 20, 1995. These chapters summarize the objectives, status and conclusions of the major project activities performed during the project period. The report concludes by describing technology transfer activities stemming from the project and providing a reference list of all publications of original research work generated by the project team or by others regarding this project. The overall objective of this project was a final research and development in the United States a technology that was developed at the Institute for Geology and Development of Fossil Fuels in Moscow, Russia. Before the technology can be convincingly adopted by United States oil and gas producers, the laboratory research was conducted at Mew Mexico Institute of Mining and Technology. The experimental studies were conducted to measure the volume and the pressure of the CO{sub 2} gas generated according to the new Russian technology. Two experimental devices were designed, built and used at New Mexico Tech facilities for these purposes. The designed setup allowed initiating and controlling the reaction between the 'gas-yielding' (GY) and 'gas-forming' (GF) agents proposed by Russian technology. The temperature was controlled, and the generated gas pressure and volume were recorded during the reaction process. Additionally, the effect of surfactant addition on the effectiveness of the process was studied. An alternative GY reactant was tested in order to increase the efficiency of the CO2 gas generation process. The slim tube and the core flood experimental studies were conducted to define the sweep efficiency of the in-situ generated CO{sub 2} gas. A set of core flood experiments were conducted to define effect of surfactant on recovery efficiency. The results demonstrated obvious advantages of the foamy system over the brine solution in order to achieve higher sweep efficiency and recovery coefficient. It is shown that a slug injection is not an efficient method for mixing GY and GF solutions and it can't generate considerable gas inside the slim-tube.

Multivariate Modeling of 3D9C Data for Constructing a Static Reservoir Model of Algal Mounds in the Paradox Basin, CO Multivariate Modeling of 3D9C Data for Constructing a Static Reservoir Model of Algal Mounds in the Paradox Basin, CO Multivariate Modeling of 3D9C Data for Constructing a Static Reservoir Model of Algal Mounds in the Paradox Basin, CO Authors: Paul La Pointe, FracMan Technology Group, Golder Associates Inc., Redmond, WA; Robert D. Benson, Colorado School of Mines, Golden, CO; and Claudia Rebne, Legacy Energy, Denver, CO. Venue: American Association of Petroleum Geologists/Rocky Mountain Section Annual Meeting in Snowbird, UT, October 7-9, 2007. Abstract: A 3D9C survey was carried out over a 6 square mile portion of the Roadrunner and Towaoc fields on the Ute Mountain Ute reservation in southwestern Colorado. This survey was jointly funded by DOE and the Southern Ute tribeÂ’s Red Willow Corporation to promote development of Ismay algal mound plays in the Paradox Basin within Ute Mountain Tribal lands and elsewhere in the Paradox Basin. Multicomponent data were utilized to better delineate the external mound geometry as well as to estimate internal mound reservoir parameters such as matrix permeability, saturation, and porosity. Simple cross-plotting of various multicomponent attributes against reservoir properties did not provide the desired predictive accuracy, in part due to sub-optimal frequency content in components derived from the shear wave data. However, a multivariate statistical analysis greatly improved the predictive accuracy. These multivariate regressions were then used to prescribe reservoir properties for a static reservoir model, which in turn formed the basis for a dynamic reservoir simulation model of the project area to assess the usefulness of the multivariate relations developed. This poster presentation will illustrate the workflow used to carry out the multivariate modeling, key maps of the reservoir properties that were derived, the static model, and results from the dynamic simulation used to assess the usefulness of the approach. Results from wells drilled based on the seismic data also will be presented.

Detailed Imaging of Facies and Fluid Distribution Within Carbonate Oil Reservoirs Detailed Imaging of Facies and Fluid Distribution Within Carbonate Oil Reservoirs Crosswell Seismic Amplitude-Versus-Offset for Detailed Imaging of Facies and Fluid Distribution Within Carbonate Oil Reservoirs Authors: Sean P. Trisch, Wayne D. Pennington, and Roger Turpening, Michigan Technological University, Houghton, MI. Venue: Seismological Society of America’s annual meeting in Waikaloa, Kona, HI., April 11–13, 2007 Abstract: Imaging of the Earth’s crust is increasingly being accomplished through the use of borehole-based sensors. Experience gained in recent crosswell seismic surveys may assist endeavors to image the near-borehole environment near plate boundaries or other places of scientific interest. A high-resolution crosswell seismic data set was collected over a Silurian (Niagaran) reef in Michigan’s Lower Peninsula. The survey was optimized for both reflection imaging purposes and the gathering of a wide range of incidence angles. The reflection image was intended to aid in interpretation of the reef structure at a level of detail never before possible with seismic methods. The survey was also conducted to maximize data available for study of the dependence of amplitudes with angle-of-incidence. Prestack angle data were processed to half-degree intervals and utilized for enhanced interpretation of the seismic image through partial stacks and through amplitude variation with angle (AVA) analyses. Frequencies as high as 3,000 Hz (the limit of the source sweep) were recorded, with a predominant signal at about 2,000 Hz; the well separation was 600 m, and the target reef is at 1,400–1,525 m depth. Many of the interfaces present within the area have small reflection amplitudes at narrow angles that increase substantially near the critical angle. Analyses were performed on various interfaces in the seismic section to compare with Zoeppritz-equation solutions, using rock data acquired through an extensive library of seismic and well logging data available for the area. These models were then compared with the actual AVA character acquired at the interface and matched as closely as possible. Through this analysis and match process, various rock property estimates were inferred or refined.

A TECHNOLOGY ASSESSMENT AND FEASIBILITY EVALUATION OF NATURAL GAS ENERGY FLOW MEASUREMENT ALTERNATIVES  

Science Conference Proceedings (OSTI)

Deregulation and open access in the natural gas pipeline industry has changed the gas business environment towards greater reliance on local energy flow rate measurement. What was once a large, stable, and well-defined source of natural gas is now a composite from many small suppliers with greatly varying gas compositions. Unfortunately, the traditional approach to energy flow measurement [using a gas chromatograph (GC) for composition assay in conjunction with a flow meter] is only cost effective for large capacity supplies (typically greater than 1 to 30 million scfd). A less costly approach will encourage more widespread use of energy measurement technology. In turn, the US will benefit from tighter gas inventory control, more efficient pipeline and industrial plant operations, and ultimately lower costs to the consumer. An assessment of the state and direction of technology for natural gas energy flow rate measurement is presented. The alternative technologies were ranked according to their potential to dramatically reduce capital and operating and maintenance (O and M) costs, while improving reliability and accuracy. The top-ranked technologies take an unconventional inference approach to the energy measurement problem. Because of that approach, they will not satisfy the fundamental need for composition assay, but have great potential to reduce industry reliance on the GC. Technological feasibility of the inference approach was demonstrated through the successful development of data correlations that relate energy measurement properties (molecular weight, mass-based heating value, standard density, molar ideal gross heating value, standard volumetric heating value, density, and volume-based heating value) to three inferential properties: standard sound speed, carbon dioxide concentration, and nitrogen concentration (temperature and pressure are also required for the last two). The key advantage of this approach is that inexpensive on-line sensors may be used to measure the inferential variables, which can then be applied (through the data correlations) to convert existing flow meters (ultrasonic, orifice, turbine, rotary, Coriolis, diaphragm, etc.) for on-line energy measurement.

In situ experiments of geothermal well stimulation using gas fracturing technology  

DOE Green Energy (OSTI)

The results of an experimental study of gas fracturing technology for geothermal well stimulation demonstrated that multiple fractures could be created to link water-filled boreholes with existing fractures. The resulting fracture network and fracture interconnections were characterized by mineback as well as flow tests. Commercial oil field fracturing tools were used successfully in these experiments. Simple scaling laws for gas fracturing and a brief discussion of the application of this technique to actual geothermal well stimulation are presented. 10 refs., 42 figs., 4 tabs.

STATE OF THE ART AND FUTURE DEVELOPMENTS IN NATURAL GAS ENGINE TECHNOLOGIES  

DOE Green Energy (OSTI)

Current, state of the art natural gas engines provide the lowest emission commercial technology for use in medium heavy duty vehicles. NOx emission levels are 25 to 50% lower than state of the art diesel engines and PM levels are 90% lower than non-filter equipped diesels. Yet, in common with diesel engines, natural gas engines are challenged to become even cleaner and more efficient to meet environmental and end-user demands. Cummins Westport is developing two streams of technologies to achieve these goals for medium-heavy and heavy-heavy duty applications. For medium-heavy duty applications, lowest possible emissions are sought on SI engines without significant increase in complexity and with improvements in efficiency and BMEP. The selected path builds on the capabilities of the CWI Plus technology and recent diesel engine advances in NOx controls, providing potential to reduce emissions to 2010 values in an accelerated manner and without the use of Selective Catalytic Reduction or NOx Storage and Reduction technology. For heavy-heavy duty applications where high torque and fuel economy are of prime concern, the Westport-Cycle{trademark} technology is in field trial. This technology incorporates High Pressure Direct Injection (HPDI{trademark}) of natural gas with a diesel pilot ignition source. Both fuels are delivered through a single, dual common rail injector. The operating cycle is entirely unthrottled and maintains the high compression ratio of a diesel engine. As a result of burning 95% natural gas rather than diesel fuel, NOx emissions are halved and PM is reduced by around 70%. High levels of EGR can be applied while maintaining high combustion efficiency, resulting in extremely low NOx potential. Some recent studies have indicated that DPF-equipped diesels emit less nanoparticles than some natural gas vehicles [1]. It must be understood that the ultrafine particles emitted from SI natural gas engines are generally accepted to consist predominantly of VOCs [2], and that lubricating oil is a major contributor. Fitting an oxidation catalyst to the natural gas engine leads to a reduction in nanoparticles emissions in comparison to engines without aftertreatment [2,3,4]. In 2001, the Cummins Westport Plus technology was introduced with the C Gas Plus engine, a popular choice for transit bus applications. This incorporates drive by wire, fully integrated, closed loop electronic controls and a standard oxidation catalyst for all applications. The B Gas Plus and the B Propane Plus engines, with application in shuttle and school buses were launched in 2002 and 2003. The gas-specific oxidation catalyst operates in concert with an optimized ring-pack and liner combination to reduce total particulate mass below 0.01g/bhphr, combat ultrafine particles and control VOC emissions.

Greenhouse gas emission impacts of alternative-fueled vehicles: Near-term vs. long-term technology options  

DOE Green Energy (OSTI)

Alternative-fueled vehicle technologies have been promoted and used for reducing petroleum use, urban air pollution, and greenhouse gas emissions. In this paper, greenhouse gas emission impacts of near-term and long-term light-duty alternative-fueled vehicle technologies are evaluated. Near-term technologies, available now, include vehicles fueled with M85 (85% methanol and 15% gasoline by volume), E85 (85% ethanol that is produced from corn and 15% gasoline by volume), compressed natural gas, and liquefied petroleum gas. Long-term technologies, assumed to be available around the year 2010, include battery-powered electric vehicles, hybrid electric vehicles, vehicles fueled with E85 (ethanol produced from biomass), and fuel-cell vehicles fueled with hydrogen or methanol. The near-term technologies are found to have small to moderate effects on vehicle greenhouse gas emissions. On the other hand, the long-term technologies, especially those using renewable energy (such as biomass and solar energy), have great potential for reducing vehicle greenhouse gas emissions. In order to realize this greenhouse gas emission reduction potential, R and D efforts must continue on the long-term technology options so that they can compete successfully with conventional vehicle technology.

Application of new and novel fracture stimulation technologies to enhance the deliverability of gas storage wells  

SciTech Connect

Based on the information presented in this report, our conclusions regarding the potential for new and novel fracture stimulation technologies to enhance the deliverability of gas storage wells are as follows: New and improved gas storage well revitalization methods have the potential to save industry on the order of $20-25 million per year by mitigating deliverability decline and reducing the need for costly infill wells Fracturing technologies have the potential to fill this role, however operators have historically been reluctant to utilize this approach due to concerns with reservoir seal integrity. With advanced treatment design tools and methods, however, this risk can be minimized. Of the three major fracturing classifications, namely hydraulic, pulse and explosive, two are believed to hold potential to gas storage applications (hydraulic and pulse). Five particular fracturing technologies, namely tip-screenout fracturing, fracturing with liquid carbon dioxide, and fracturing with gaseous nitrogen, which are each hydraulic methods, and propellant and nitrogen pulse fracturing, which are both pulse methods, are believed to hold potential for gas storage applications and will possibly be tested as part of this project. Field evidence suggests that, while traditional well remediation methods such as blowing/washing, mechanical cleaning, etc. do improve well deliverability, wells are still left damaged afterwards, suggesting that considerable room for further deliverability enhancement exists. Limited recent trials of hydraulic fracturing imply that this approach does in fact provide superior deliverability results, but further RD&D work is needed to fully evaluate and demonstrate the benefits and safe application of this as well as other fracture stimulation technologies.

Mineral-wool industry: opportunities for natural gas technologies. Topical report, January-July 1987  

SciTech Connect

To quantify the opportunities for natural gas and identify technological advances needed to capture such opportunities, the mineral-wool industry was analyzed with respect to the principal companies, their capabilities, and markets. The mineral-wool industry is stable with a slightly declining market. Of its market segments, only commercial acoustic insulation (which is currently dominant) is likely to be affected by growth in the next ten years. The principal process is based on treatment of blast-furnace slags in a cupola furnace using coke as the fuel and reducing agent. Expanded use of gas, as a substitute for coke, would eliminate environmental problems and expand the latitude of suitable raw materials. The study provides insights into the mineral-wool industry and identifies factors that may constitute bases for future usage of natural gas.

Topsoe`s Wet gas Sulfuric Acid (WSA) process: An alternative technology for recovering refinery sulfur  

SciTech Connect

The Topsoe Wet gas Sulfuric Acid (WSA) process is a catalytic process which produces concentrated sulfuric acid from refinery streams containing sulfur compounds such as H{sub 2}S (Claus plant feed), Claus plant tail gas, SO{sub 2} (FCC off-gas, power plants), and spent sulfuric acid (alkylation acid). The WSA process recovers up to 99.97% of the sulfur value in the stream as concentrated sulfuric acid (93--98.5 wt%). No solid waste products or waste water is produced and no chemicals are consumed in the process. The simple process layout provides low capital cost and attractive operating economy. Twenty four commercial WSA plants have been licensed. The WSA process is explained in detail and comparisons with alternative sulfur management technology are presented. Environmental regulations applying to SO{sub x} abatement and sulfuric acid production plants are explained in the context of WSA plant operation.

Fuel-cycle greenhouse gas emissions impacts of alternative transportation fuels and advanced vehicle technologies.  

DOE Green Energy (OSTI)

At an international conference on global warming, held in Kyoto, Japan, in December 1997, the United States committed to reduce its greenhouse gas (GHG) emissions by 7% over its 1990 level by the year 2012. To help achieve that goal, transportation GHG emissions need to be reduced. Using Argonne's fuel-cycle model, I estimated GHG emissions reduction potentials of various near- and long-term transportation technologies. The estimated per-mile GHG emissions results show that alternative transportation fuels and advanced vehicle technologies can help significantly reduce transportation GHG emissions. Of the near-term technologies evaluated in this study, electric vehicles; hybrid electric vehicles; compression-ignition, direct-injection vehicles; and E85 flexible fuel vehicles can reduce fuel-cycle GHG emissions by more than 25%, on the fuel-cycle basis. Electric vehicles powered by electricity generated primarily from nuclear and renewable sources can reduce GHG emissions by 80%. Other alternative fuels, such as compressed natural gas and liquefied petroleum gas, offer limited, but positive, GHG emission reduction benefits. Among the long-term technologies evaluated in this study, conventional spark ignition and compression ignition engines powered by alternative fuels and gasoline- and diesel-powered advanced vehicles can reduce GHG emissions by 10% to 30%. Ethanol dedicated vehicles, electric vehicles, hybrid electric vehicles, and fuel-cell vehicles can reduce GHG emissions by over 40%. Spark ignition engines and fuel-cell vehicles powered by cellulosic ethanol and solar hydrogen (for fuel-cell vehicles only) can reduce GHG emissions by over 80%. In conclusion, both near- and long-term alternative fuels and advanced transportation technologies can play a role in reducing the United States GHG emissions.

Technology-Based Technology-Based Oil and Natural Gas Plays: Shale Shock! Could There Be Billions in the Bakken? Through the use of technology, U.S. oil and natural gas operators are converting previously uneconomic oil and natural gas resources into proved reserves and production. The Bakken Formation of the Williston Basin is a success story of horizontal drilling, fracturing, and completion technologies. The recent, highly productive oil field discoveries within the Bakken Formation did not come from venturing out into deep uncharted waters heretofore untapped by man, nor from blazing a trail into pristine environs never open to drilling before. Instead, success came from analysis of geologic data on a decades-old producing area, identification of uptapped resources, and application of the new drilling and completion technology necessary to exploit them.

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

E-Print Network (OSTI)

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

Demonstration of Natural Gas Engine Driven Air Compressor Technology at Department of Defense Industrial Facilities  

E-Print Network (OSTI)

Recent downsizing and consolidation of Department of Defense (DOD) facilities provides an opportunity to upgrade remaining facilities with more efficient and less polluting equipment. Use of air compressors by the DOD is widespread and the variety of tools and machinery that operate on compressed air is increasing. The energy cost of operating a natural gas engine-driven air compressor (NGEDAC) is usually lower than the cost of operating an electric-driven air compressor. Initial capital costs are offset by differences in prevailing utility rates, efficiencies of partial load operation, reductions in peak demand, heat recovery, and avoiding the cost of back-up generators. Natural gas, a clean-burning fuel, is abundant and readily available. In an effort to reduce its over-all environmental impact and energy consumption, the U.S. Army plans to apply NGEDAC technology in support of fixed facilities compressed air systems. Site assessment and demonstration results are presented in this paper.

Hydrogen Gas Production from Nuclear Power Plant in Relation to Hydrogen Fuel Cell Technologies Nowadays  

Science Conference Proceedings (OSTI)

Recently, world has been confused by issues of energy resourcing, including fossil fuel use, global warming, and sustainable energy generation. Hydrogen may become the choice for future fuel of combustion engine. Hydrogen is an environmentally clean source of energy to end-users, particularly in transportation applications because without release of pollutants at the point of end use. Hydrogen may be produced from water using the process of electrolysis. One of the GEN-IV reactors nuclear projects (HTGRs, HTR, VHTR) is also can produce hydrogen from the process. In the present study, hydrogen gas production from nuclear power plant is reviewed in relation to commercialization of hydrogen fuel cell technologies nowadays.

TECHNOLOGY TRANSFER TO U.S. INDEPENDENT OIL AND NATURAL GAS PRODUCERS  

SciTech Connect

The Petroleum Technology Transfer Council (PTTC) continued pursuing its mission of helping U.S. independent oil and natural gas producers make timely, informed technology decisions. PTTC's Board made a strategic decision to relocate the Headquarters (HQ) office from Washington, DC to Houston, Texas. Driving force behind relocation was to better connect with independent producers, but cost savings could also be realized. Relocation was accomplished in late December 2000, with the HQ office being fully operational by January 2001. Early indications are that the HQ relocation is, in fact, enabling better networking with senior executives of independents in the Houston oil community. New Board leadership, elected in March 2001, will continue to effectively guide PTTC.

the Performance of Class 2 and Class 3 Hydrate Deposits during Co-Production with Conventional Gas the Performance of Class 2 and Class 3 Hydrate Deposits during Co-Production with Conventional Gas The Performance of Class 2 and Class 3 Hydrate Deposits during Co-Production with Conventional Gas (OTC 19435) Authors: George J. Moridis (speaker), Matthew T. Reagan, and Keni Zhang Venue: 2008 Offshore Technology Conference, Houston, Texas, May 5-8, 2008 ( http://www.spe.org and http://www.smenet.org [external sites] ) Abstract: Recent numerical studies have provided strong indications that it is possible to produce large volumes of gas from natural hydrate deposits at high rates (in excess of 10 MMSCFD) for long times by depressurization-induced dissociation of hydrates. Of the various factors that can adversely affect the production potential of hydrates, low temperatures have one of the strongest negative impacts. These can be caused by low initial temperatures, increasing stability of the hydrate (as defined by the deviation between the temperature of the deposit and the equilibrium temperature at the reservoir pressure), and by an advanced stage of dissociation (a strongly endothermic reaction) when substantial amounts of hydrates remain. The reasons for the production decline include a reduction in the rate of the hydrate dissociation at lower temperatures and the evolution of flow restrictions in the vicinity of the well caused by the formation of hydrate and/or ice in the vicinity of the wellbore. The latter is caused by continuous cooling, and is the reason why large amounts of gas that may have been released in the reservoir in the course of earlier dissociation cannot be easily recovered.

Advanced Acid Gas Separation Technology for the Utilization of Low Rank Coals  

SciTech Connect

Air Products has developed a potentially ground-breaking technology – Sour Pressure Swing Adsorption (PSA) – to replace the solvent-based acid gas removal (AGR) systems currently employed to separate sulfur containing species, along with CO{sub 2} and other impurities, from gasifier syngas streams. The Sour PSA technology is based on adsorption processes that utilize pressure swing or temperature swing regeneration methods. Sour PSA technology has already been shown with higher rank coals to provide a significant reduction in the cost of CO{sub 2} capture for power generation, which should translate to a reduction in cost of electricity (COE), compared to baseline CO{sub 2} capture plant design. The objective of this project is to test the performance and capability of the adsorbents in handling tar and other impurities using a gaseous mixture generated from the gasification of lower rank, lignite coal. The results of this testing are used to generate a high-level pilot process design, and to prepare a techno-economic assessment evaluating the applicability of the technology to plants utilizing these coals.

TECHNOLOGY TRANSFER TO U.S. INDEPENDENT OIL AND NATURAL GAS PRODUCERS  

Science Conference Proceedings (OSTI)

The Petroleum Technology Transfer Council (PTTC) continued pursuing its mission of assisting U.S. independent oil and gas producers to make timely, informed technology decisions. Functioning as a cohesive national organization, PTTC has active grassroots programs through its 10 Regional Lead Organizations (RLOs) and 3 Satellite Offices that encompass all of the oil- and natural gas-producing regions in the U.S. Active volunteer leadership from the Board and regional Producer Advisory Groups keeps activities focused on producer's needs. Technical expertise and personal networks of national and regional staff enable PTTC to deliver focused, technology-related information in a manner that is cost and time effective for independents. The organization effectively combines federal funding through the Department of Energy's (DOE) Office of Fossil Energy with matching state and industry funding, forming a unique partnership. This final report summarizes PTTC's accomplishments. In this final fiscal year of the contract, activities exceeded prior annual activity levels by significant percentages. Strategic planning implemented during the year is focusing PTTC's attention on changes that will bear fruit in the future. Networking and connections are increasing PTTC's sphere of influence with both producers and the service sector. PTTC's reputation for unbiased bottom-line information stimulates cooperative ventures. In FY03 PTTC's regions held 169 workshops, drawing 8,616 attendees. There were nearly 25,000 reported contacts. This represents a 38% increase in attendance and 34% increase in contacts as compared to FY02 activity. Repeat attendance at regional workshops, a measure of customer satisfaction and value received, remained strong at 50%. 39% of participants in regional workshops respond ''Yes'' on feedback forms when asked if they are applying technologies based on knowledge gained through PTTC. This feedback confirms that producers are taking action with the information they receive. RLO Directors captured examples demonstrating how PTTC activities influenced industry activity. Additional follow-up in all regions explored industry's awareness of PTTC and the services it provides. PTTC publishes monthly case studies in the ''Petroleum Technology Digest in World Oil'' and monthly Tech Connections columns in the ''American Oil and Gas Reporter''. Email Tech Alerts are utilized to notify the O&G community of DOE solicitations and demonstration results, PTTC key technical information and meetings, as well as industry highlights. Workshop summaries are posted online at www.pttc.org. PTTC maintains an active exhibit schedule at national industry events. The national communications effort continues to expand the audience PTTC reaches. The network of national and regional websites has proven effective for conveying technology-related information and facilitating user's access to basic oil and gas data, which supplement regional and national newsletters. The regions frequently work with professional societies and producer associations in co-sponsored events and there is a conscious effort to incorporate findings from DOE-supported research, development and demonstration (RD&D) projects within events. The level of software training varies by region, with the Rocky Mountain Region taking the lead. Where appropriate, regions develop information products that provide a service to industry and, in some cases, generate moderate revenues. Data access is an on-going industry priority, so all regions work to facilitate access to public source databases. Various outreach programs also emanate from the resource centers, including targeted visits to producers.

Slow-light solitons revisited  

E-Print Network (OSTI)

We investigate propagation of slow-light solitons in atomic media described by the nonlinear $\\Lambda$-model. Under a physical assumption, appropriate to the slow light propagation, we reduce the $\\Lambda$-scheme to a simplified nonlinear model, which is also relevant to 2D dilatonic gravity. Exact solutions describing various regimes of stopping slow-light solitons can then be readily derived.

The Fuel Processing Research Facility - A Platform for the Conduct of Synthesis Gas Technology R&D  

DOE Green Energy (OSTI)

Vision 21 is the U. S. Department of Energy's initiative to deploy high efficiency, ultraclean co-production coal conversion power plants in the twenty-first century. These plants will consist of power and co-production modules, which are integrated to meet specific power and chemical markets. A variety of fuel gas processing technology issues involving gas separations, cleanup, gas-to-liquid fuels production and chemical synthesis, to mention a few, will be addressed by the program. The overall goal is to effectively eliminate, at competitive costs, environmental concerns associated with the use of fossil fuels for producing electricity and transportation fuels. The Fuel Processing Research Facility (FPRF) was developed as a fuel-flexible platform to address many of these technology needs. The facility utilizes a simplified syngas generator that is capable of producing 2,000 standard cubic feet per hour of 900 degree Celsius and 30 atmosphere synthesis gas that can be tailored to the gas composition of interest. It was built on a ''mid-scale'' level in an attempt to successfully branch the traditionally difficult scale-up from laboratory to pilot scale. When completed, the facility will provide a multi-faceted R&D area for the testing of fuel cells, gas separation technologies, and other gas processing unit operations.

Near-Zero NOx Combustion Technology for ATS Mercury 50 Gas Turbine  

SciTech Connect

A project to demonstrate a near-zero NOx, catalytic combustion technology for natural gas-fired, industrial gas turbines is described. In a cooperative effort between Solar Turbines Incorporated and Precision Combustion Incorporated (PCI), proof-of-concept rig testing of PCI's fuel-rich catalytic combustion technology has been completed successfully. The primary technical goal of the project was to demonstrate NOx and CO emissions below 5ppm and 10 ppm, respectively, (corrected to 15% O{sub 2}) at realistic gas turbine operating conditions. The program consisted of two tasks. In the first task, a single prototype RCL{trademark} (Rich Catalytic Lean Burn) module was demonstrated at Taurus 70 (7.5 Mw) operating conditions (1.6 MPa, 16 atm) in a test rig. For a Taurus 70 engine, eight to twelve RCL modules will be required, depending on the final system design. In the second task, four modules of a similar design were adapted to a Saturn engine (1 Mw) test rig (600 kPa, 6 atm) to demonstrate gas turbine light-off and operation with an RCL combustion system. This project was initially focused on combustion technology for the Mercury 50 engine. However, early in the program, the Taurus 70 replaced the Mercury. This substitution was motivated by the larger commercial market for an ultra-low NOx Taurus 70 in the near-term. Rig tests using a single prototype RCL module at Taurus 70 conditions achieved NOx emissions as low as 0.75 ppm. A combustor turndown of approximately 110C (200F) was achieved with NOx and CO emissions below 3 ppm and 10 ppm, respectively. Catalyst light-off occurred at an inlet temperature of 310C (590F). Once lit the module remained active at inlet air temperatures as low as 204C (400F). Combustor pressure oscillations were acceptably low during module testing. Single module rig tests were also conducted with the Taurus 70 module reconfigured with a central pilot fuel injector. Such a pilot will be required in a commercial RCL system for turbine light-off and transient operation. At and near simulated full load engine conditions, the pilot operated at low pilot fueling rates without degrading overall system emissions. In the second project task, a set of four Taurus 70 modules was tested in an existing Saturn engine rig. The combustion system allowed smooth engine startup and load variation. At steady state conditions (between 82% and 89.7% engine speed; 32% and 61% load), NOx and CO emissions were below 3ppm and 10ppm, respectively. Rig limitations unrelated to the RCL technology prevented low emissions operation outside of this speed range. Combustor pressure oscillations were low, below 0.25 % (peak-to-peak) of the mean combustor pressure.

Assessing the Potential of Using Hydrate Technology to Capture, Store and Transport Gas for the Caribbean Region  

E-Print Network (OSTI)

Monetizing gas has now become a high priority issue for many countries. Natural gas is a much cleaner fuel than oil and coal especially for electricity generation. Approximately 40 percent of the world's natural gas reserves remain unusable because of lack of economic technology. Gas produced with oil poses a challenge of being transported and is typically flared or re-injected into the reservoir. These are gas transportation issues we now face. Gas hydrate may be a viable means of capturing, storing and transporting stranded and associated gas. For example, stranded gas in Trinidad could be converted to gas hydrates and transported to the islands of the Caribbean. This study will seek to address some of the limitations from previous studies on transporting natural gas as a hydrate while focusing on small scale transportation of natural gas to the Caribbean Islands. This work proposes a workflow for capturing, storing and transporting gas in the hydrate form, particularly for Caribbean situations where there are infrastructural constraints such as lack of pipelines. The study shows the gas hydrate value chain for transportation of 5 MMscf/d of natural gas from Trinidad to Jamaica. The analysis evaluated the water required for hydrate formation, effect of composition on hydrate formation, the energy balance of the process, the time required for formation, transportation and dissociation and preliminary economics. The overall energy requirement of the process which involves heating, cooling and expansion is about 15-20 percent of the energy of the gas transported in hydrate form. The time estimated for the overall process is 20–30 hrs. The estimated capital cost to capture and transport 5 MMscf/d from Trinidad to Jamaica is about US$ 30 million. The composition of the gas sample can affect the conditions of formation, heating value and the expansion process. In summary, there is great potential for transporting natural gas by gas hydrate on a small scale based on the proposed hydrate work flow. This study did not prove commerciality at this time, however, some of the limitations require further evaluations and these include detailed modeling of the formation time, dissociation time and heat transfer capabilities.

Final Report on Testing of Off-Gas Treatment Technologies for Abatement of Atmospheric Emissions of Chlorinated Volatile Organic Compounds  

SciTech Connect

The purpose of this report is to summarize the results of the program for off-gas treatment of atmospheric emissions of chlorinated volatile organic compounds (CVOCs), in particular trichloroethylene (TCE) and perchloroethylene (PCE). This program was funded through the Department of Energy Office of Technology Development`s VOC`s in Non-Arid Soils Integrated Demonstration (VNID). The off-gas treatment program was initiated after testing of in-situ air stripping with horizontal wells was completed (Looney et al., 1991). That successful test expectedly produced atmospheric emissions of CVOCs that were unabated. It was decided after that test that an off-gas treatment is an integral portion of remediation of CVOC contamination in groundwater and soil but also because several technologies were being developed across the United States to mitigate CVOC emissions. A single platform for testing off-gas treatment technologies would facilitate cost effective evaluation of the emerging technologies. Another motivation for the program is that many CVOCs will be regulated under the Clean Air Act Amendments of 1990 and are already regulated by many state regulatory programs. Additionally, compounds such as TCE and PCE are pervasive subsurface environmental contaminants, and, as a result, a small improvement in terms of abatement efficiency or cost will significantly reduce CVOC discharges to the environment as well as costs to United States government and industry.

High-temperature turbine technology program hot-gas path development test. Part II. Testing  

SciTech Connect

This topical report of the US Department of Energy High-Temperature Turbine Technology (DOE-HTTT) Phase II program presents the results of testing full-scale water-cooled first-stage and second-stage turbine nozzles at design temperature and pressure to verify that the designs are adequate for operation in a full-scale turbine environment. Low-cycle fatigue life of the nozzles was demonstrated by subjecting cascade assemblies to several hundred simulated startup/shutdown turbine cycles. This testing was accomplished in the Hot-Gas Path Development Test Stand (HGPDTS), which is capable of evaluating full-scale combustion and turbine nozzle components. A three-throat cascade of the first-stage turbine nozzle was successfully tested at a nozzle inlet gas temperature of 2630/sup 0/F and a nozzle inlet pressure of 11.3 atmospheres. In addition to steady-state operation at the design firing temperature, the nozzle cascade was exposed to a simulated startup/shutdown turbine cycle by varying the firing temperature. A total of 42 h at the design point and 617 thermal cycles were accumulated during the test periods. First-stage nozzle test results show that measured metal and coolant temperatures correspond well to the predicted design values. This nozzle design has been shown to be fully satisfactory for the application (2600/sup 0/F), with growth capability to 3000/sup 0/F firing temperature. A post-test metallurgical examination of sectioned portions of the tested nozzles shows a totally bonded structure, confirming the test results and attesting to the successful performance of water-cooled composite nozzle hardware.

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston/ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and emissions. An iterative process of simulation, experimentation and analysis, are being followed towards achieving the goal of demonstrating a complete optimized low-friction engine system. To date, a detailed set of piston/ring dynamic and friction models have been developed and applied that illustrated the fundamental relationships between design parameters and friction losses. Various low-friction strategies and ring-design concepts have been explored, and engine experiments have been done on a full-scale Waukesha VGF F18 in-line 6 cylinder power generation engine rated at 370 kW at 1800 rpm. Current accomplishments include designing and testing ring-packs using a subtle top-compression-ring profile (skewed barrel design), lowering the tension of the oil-control ring, employing a negative twist to the scraper ring to control oil consumption. Initial test data indicate that piston ring-pack friction was reduced by 35% by lowering the oil-control ring tension alone, which corresponds to a 1.5% improvement in fuel efficiency. Although small in magnitude, this improvement represents a first step towards anticipated aggregate improvements from other strategies. Other ring-pack design strategies to lower friction have been identified, including reduced axial distance between the top two rings, tilted top-ring groove. Some of these configurations have been tested and some await further evaluation. Colorado State University performed the tests and Waukesha Engine Dresser, Inc. provided technical support. Key elements of the continuing work include optimizing the engine piston design, application of surface and material developments in conjunction with improved lubricant properties, system modeling and analysis, and continued technology demonstration in an actual full-sized reciprocating natural-gas engine.

IMPROVED TUBULARS FOR BETTER ECONOMICS IN DEEP GAS WELL DRILLING USING MICROWAVE TECHNOLOGY  

Science Conference Proceedings (OSTI)

The main objective of the research program has been to improve the rate-of-penetration in deep hostile environments by improving the life cycle and performance of coiled-tubing, an important component of a deep well drilling system for oil and gas exploration, by utilizing the latest developments in the microwave materials technology. Originally, it was proposed to accomplish this by developing an efficient and economically viable continuous microwave process to sinter continuously formed/extruded steel powder for the manufacture of seamless coiled tubing and other tubular products. However, based on the results and faced with insurmountable difficulties in the extrusion and de-waxing processes, the approach of achieving the goals of the program has been slightly changed. In the continuation proposal an approach of microwave sintering combined with Cold Isostatic Press (CIP) and joining (by induction or microwave) is adopted. This process can be developed into a semi-continuous sintering process if the CIP can produce parts fast enough to match the microwave sintering rates. Originally, the entire program was spread over three phases with the following goals: Phase I: Demonstration of the feasibility concept of continuous microwave sintering process for tubular steel products. Phase II: Design, building and testing of a prototype microwave system which shall be combined with a continuous extruder for steel tubular objects. Phase III: Execution of the plan for commercialization of the technology by one of the industrial partners. However, since some of the goals of the phase I were not completed, an extension of nine months was granted and we continued extrusion experiments, designed and built semicontinuous microwave sintering unit.

Health and environmental effects of oil and gas technologies: research needs  

Science Conference Proceedings (OSTI)

This report discusses health and environmental issues associated with oil and gas technologies as they are currently perceived - both those that exist and those that are expected to emerge over the next two decades. The various sections of this report contain discussions of specific problem areas and relevant new research activities which should be pursued. This is not an exhaustive investigation of all problem areas, but the report explores a wide range of issues to provide a comprehensive picture of existing uncertainties, trends, and other factors that should serve as the focus of future research. The problem areas of major concern include: effects of drilling fluids, offshore accidents, refineries and worker health, and biota and petroleum spills, indoor air pollution, information transfer, and unconventional resources. These are highlighted in the Executive Summary because they pose serious threats to human health and the environment, and because of the sparcity of accumulated knowledge related to their definition. Separate abstracts have been prepared for selected sections of this report for inclusion in the Energy Data Base. (DMC)

Application of coiled-tubing-drilling technology on a deep underpressured gas reservoir  

Science Conference Proceedings (OSTI)

The Upper-Mississippian Elkton formation is a dolomitized shallow-water carbonate consisting of dense limestones and porous dolomites. The Elkton was deposited in an open-shelf environment as crinoid grainstones, coral packstones, and lime muds. Deposition of impermeable shales and siltstones of the Lower Cretaceous created the lateral and updip seals. Reservoir thickness can be up to 20 m, with porosities reaching 20% and averaging 10%. The reservoir gas contains approximately 0.5% hydrogen sulfide. Well 11-18 was to be completed in the Harmatten Elkton pool. The pool went on production in 1967 at an initial pressure of 23,500 kPa. At the current pressure of 16,800 kPa, the remaining reserves are underpressured at 6.5 kPa/m, and underbalanced horizontal drilling was selected as the most suitable technique for exploiting remaining reserves. Coiled-tubing (CT) technology was selected to ensure continuous underbalanced conditions and maintain proper well control while drilling. The paper describes the equipment, CT drilling summary, and drilling issues.

After the completion of the Phase II, it is concluded that scale up and sintering of a thin wall common O.D. size tubing that is widely used in the market is still to be proved and further experimentation and refinement of the sintering process is needed in Phase III. Actual manufacturing capability of microwave sintered, industrial quality, full length tubing will most likely require several million dollars of investment.

Integrated Warm Gas Multicontaminant Cleanup Technologies for Coal-Derived Syngas  

SciTech Connect

One of the key obstacles for the introduction of commercial gasification technology for the production of power with Integrated Gasification Combined Cycle (IGCC) plants or the production of value added chemicals, transportation fuels, and hydrogen has been the cost of these systems. This situation is particularly challenging because the United States has ample coal resources available as raw materials and effective use of these raw materials could help us meet our energy and transportation fuel needs while significantly reducing our need to import oil. One component of the cost of these systems that faces strong challenges for continuous improvement is removing the undesirable components present in the syngas. The need to limit the increase in cost of electricity to < 35% for new coal-based power plants which include CO{sub 2} capture and sequestration addresses both the growing social concern for global climate change resulting from the emission of greenhouse gas and in particular CO{sub 2} and the need to control cost increases to power production necessary to meet this social objective. Similar improvements to technologies for trace contaminants are getting similar pressure to reduce environmental emissions and reduce production costs for the syngas to enable production of chemicals from coal that is cost competitive with oil and natural gas. RTI, with DOE/NETL support, has been developing sorbent technologies that enable capture of trace contaminants and CO{sub 2} at temperatures above 400 °F that achieve better capture performance, lower costs and higher thermal efficiency. This report describes the specific work of sorbent development for mercury (Hg), arsenic (As), selenium (Se), cadmium (Cd), and phosphorous (P) and CO{sub 2} removal. Because the typical concentrations of Hg, As, Se, Cd, and P are less than 10 ppmv, the focus has been on single-use sorbents with sufficient capacity to ensure replacement costs are cost effective. The research in this report describes the development efforts which expand this sorbent development effort to include Se, Cd, and P as well as Hg and As. Additional research has focused on improving removal performance with the goal of achieving effluent concentrations that are suitable for chemical production applications. By contrast, sorbent development for CO{sub 2} capture has focused on regenerable sorbents that capture the CO{sub 2} byproduct at higher CO{sub 2} pressures. Previous research on CO{sub 2} sorbents has demonstrated that the most challenging aspect of developing CO{sub 2} sorbents is regeneration. The research documented in this report investigates options to improve regeneration of the CO{sub 2} capture sorbents. This research includes effort on addressing existing regeneration limitations for sorbents previously developed and new approaches that focus initially on the regeneration performance of the sorbent.

Energy and greenhouse gas emission effects of corn and cellulosic ethanol with technology improvements and land use changes.  

Science Conference Proceedings (OSTI)

Use of ethanol as a transportation fuel in the United States has grown from 76 dam{sup 3} in 1980 to over 40.1 hm{sup 3} in 2009 - and virtually all of it has been produced from corn. It has been debated whether using corn ethanol results in any energy and greenhouse gas benefits. This issue has been especially critical in the past several years, when indirect effects, such as indirect land use changes, associated with U.S. corn ethanol production are considered in evaluation. In the past three years, modeling of direct and indirect land use changes related to the production of corn ethanol has advanced significantly. Meanwhile, technology improvements in key stages of the ethanol life cycle (such as corn farming and ethanol production) have been made. With updated simulation results of direct and indirect land use changes and observed technology improvements in the past several years, we conducted a life-cycle analysis of ethanol and show that at present and in the near future, using corn ethanol reduces greenhouse gas emission by more than 20%, relative to those of petroleum gasoline. On the other hand, second-generation ethanol could achieve much higher reductions in greenhouse gas emissions. In a broader sense, sound evaluation of U.S. biofuel policies should account for both unanticipated consequences and technology potentials. We maintain that the usefulness of such evaluations is to provide insight into how to prevent unanticipated consequences and how to promote efficient technologies with policy intervention.

OPTIMIZING TECHNOLOGY TO REDUCE MERCURY AND ACID GAS EMISSIONS FROM ELECTRIC POWER PLANTS  

DOE Green Energy (OSTI)

Maps showing potential mercury, sulfur, chlorine, and moisture emissions for U.S. coal by county of origin were made from publicly available data (plates 1, 2, 3, and 4). Published equations that predict mercury capture by emission control technologies used at U.S. coal-fired utilities were applied to average coal quality values for 169 U.S. counties. The results were used to create five maps that show the influence of coal origin on mercury emissions from utility units with: (1) hot-side electrostatic precipitator (hESP), (2) cold-side electrostatic precipitator (cESP), (3) hot-side electrostatic precipitator with wet flue gas desulfurization (hESP/FGD), (4) cold-side electrostatic precipitator with wet flue gas desulfurization (cESP/FGD), and (5) spray-dry adsorption with fabric filter (SDA/FF) emission controls (plates 5, 6, 7, 8, and 9). Net (lower) coal heating values were calculated from measured coal Btu values, and estimated coal moisture and hydrogen values; the net heating values were used to derive mercury emission rates on an electric output basis (plate 10). Results indicate that selection of low-mercury coal is a good mercury control option for plants having hESP, cESP, or hESP/FGD emission controls. Chlorine content is more important for plants having cESP/FGD or SDA/FF controls; optimum mercury capture is indicated where chlorine is between 500 and 1000 ppm. Selection of low-sulfur coal should improve mercury capture where carbon in fly ash is used to reduce mercury emissions. Comparison of in-ground coal quality with the quality of commercially mined coal indicates that existing coal mining and coal washing practice results in a 25% reduction of mercury in U.S. coal before it is delivered to the power plant. Further pre-combustion mercury reductions may be possible, especially for coal from Texas, Ohio, parts of Pennsylvania and much of the western U.S.

Greenhouse Emission Reductions and Natural Gas Vehicles: A Resource Guide on Technology Options and Project Development  

Science Conference Proceedings (OSTI)

Accurate and verifiable emission reductions are a function of the degree of transparency and stringency of the protocols employed in documenting project- or program-associated emissions reductions. The purpose of this guide is to provide a background for law and policy makers, urban planners, and project developers working with the many Greenhouse Gas (GHG) emission reduction programs throughout the world to quantify and/or evaluate the GHG impacts of Natural Gas Vehicle (NGVs). In order to evaluate the GHG benefits and/or penalties of NGV projects, it is necessary to first gain a fundamental understanding of the technology employed and the operating characteristics of these vehicles, especially with regard to the manner in which they compare to similar conventional gasoline or diesel vehicles. Therefore, the first two sections of this paper explain the basic technology and functionality of NGVs, but focus on evaluating the models that are currently on the market with their similar conventional counterparts, including characteristics such as cost, performance, efficiency, environmental attributes, and range. Since the increased use of NGVs, along with Alternative Fuel Vehicle (AFVs) in general, represents a public good with many social benefits at the local, national, and global levels, NGVs often receive significant attention in the form of legislative and programmatic support. Some states mandate the use of NGVs, while others provide financial incentives to promote their procurement and use. Furthermore, Federal legislation in the form of tax incentives or procurement requirements can have a significant impact on the NGV market. In order to implement effective legislation or programs, it is vital to have an understanding of the different programs and activities that already exist so that a new project focusing on GHG emission reduction can successfully interact with and build on the experience and lessons learned of those that preceded it. Finally, most programs that deal with passenger vehicles--and with transportation in general--do not address the climate change component explicitly, and thus there are few GHG reduction goals that are included in these programs. Furthermore, there are relatively few protocols that exist for accounting for the GHG emissions reductions that arise from transportation and, specifically, passenger vehicle projects and programs. These accounting procedures and principles gain increased importance when a project developer wishes to document in a credible manner, the GHG reductions that are achieved by a given project or program. Section four of this paper outlined the GHG emissions associated with NGVs, both upstream and downstream, and section five illustrated the methodology, via hypothetical case studies, for measuring these reductions using different types of baselines. Unlike stationary energy combustion, GHG emissions from transportation activities, including NGV projects, come from dispersed sources creating a need for different methodologies for assessing GHG impacts. This resource guide has outlined the necessary context and background for those parties wishing to evaluate projects and develop programs, policies, projects, and legislation aimed at the promotion of NGVs for GHG emission reduction.

Toward Production From Gas Hydrates: Current Status, Assessment of Resources, and Simulation-Based Evaluationof Technology and Potential  

SciTech Connect

Gas hydrates are a vast energy resource with global distribution in the permafrost and in the oceans. Even if conservative estimates are considered and only a small fraction is recoverable, the sheer size of the resource is so large that it demands evaluation as a potential energy source. In this review paper, we discuss the distribution of natural gas hydrate accumulations, the status of the primary international R&D programs, and the remaining science and technological challenges facing commercialization of production. After a brief examination of gas hydrate accumulations that are well characterized and appear to be models for future development and gas production, we analyze the role of numerical simulation in the assessment of the hydrate production potential, identify the data needs for reliable predictions, evaluate the status of knowledge with regard to these needs, discuss knowledge gaps and their impact, and reach the conclusion that the numerical simulation capabilities are quite advanced and that the related gaps are either not significant or are being addressed. We review the current body of literature relevant to potential productivity from different types of gas hydrate deposits, and determine that there are consistent indications of a large production potential at high rates over long periods from a wide variety of hydrate deposits. Finally, we identify (a) features, conditions, geology and techniques that are desirable in potential production targets, (b) methods to maximize production, and (c) some of the conditions and characteristics that render certain gas hydrate deposits undesirable for production.

LOW-ENGINE-FRICTION TECHNOLOGY FOR ADVANCED NATURAL-GAS RECIPROCATING ENGINES  

Science Conference Proceedings (OSTI)

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston and piston ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and wear. An iterative process of simulation, experimentation and analysis is being followed towards achieving the goal of demonstrating a complete optimized low-friction engine system. To date, a detailed set of piston and piston-ring dynamic and friction models have been developed and applied that illustrate the fundamental relationships between design parameters and friction losses. Low friction ring designs have already been recommended in a previous phase, with full-scale engine validation partially completed. Current accomplishments include the addition of several additional power cylinder design areas to the overall system analysis. These include analyses of lubricant and cylinder surface finish and a parametric study of piston design. The Waukesha engine was found to be already well optimized in the areas of lubricant, surface skewness and honing cross-hatch angle, where friction reductions of 12% for lubricant, and 5% for surface characteristics, are projected. For the piston, a friction reduction of up to 50% may be possible by controlling waviness alone, while additional friction reductions are expected when other parameters are optimized. A total power cylinder friction reduction of 30-50% is expected, translating to an engine efficiency increase of two percentage points from its current baseline towards the goal of 50% efficiency. Key elements of the continuing work include further analysis and optimization of the engine piston design, in-engine testing of recommended lubricant and surface designs, design iteration and optimization of previously recommended technologies, and full-engine testing of a complete, optimized, low-friction power cylinder system.

Development of Brazing Technology for Use in High- Temperature Gas Separation Equipment  

DOE Green Energy (OSTI)

The development of high-temperature electrochemical devices such as oxygen and hydrogen separators, fuel gas reformers, solid oxide fuel cells, and chemical sensors is part of a rapidly expanding segment of the solid state technology market. These devices employ an ionic conducting ceramic as the active membrane that establishes the electrochemical potential of the device, either under voltage (i.e. to carry out gas separation) or under chemical gradient (to develop an electrical potential and thereby generate electrical power). Because the device operates under an ionic gradient that develops across the electrolyte, hermiticity across this layer is paramount. That is, not only must this thin ceramic membrane be dense with no interconnected porosity, but it must be connected to the rest of the device, typically constructed from a heat resistant alloy, with a high-temperature, gas-tight seal. A significant engineering challenge in fabricating these devices is how to effectively join the thin electrochemically active membrane to the metallic body of the device such that the resulting seal is hermetic, rugged, and stable during continuous high temperature operation. Active metal brazing is the typical method of joining ceramic and metal engineering components. It employs a braze alloy that contains one or more reactive elements, often titanium, which will chemically reduce the ceramic faying surface and greatly improve its wetting behavior and adherence with the braze. However, recent studies of these brazes for potential use in fabricating high-temperature electrochemical devices revealed problems with interfacial oxidation and subsequent joint failure [1,2]. Specifically, it was found that the introduction of the ceramic electrolyte and/or heat resistant metal substrate dramatically affects the inherent oxidation behavior of the braze, often in a deleterious manner. These conclusions pointed to the need for an oxidation resistant, high-temperature ceramic-to-metal braze and consequently lead to the development of the novel reactive air brazing (RAB) concept. The goal in RAB is to reactively modify one or both oxide faying surfaces with an oxide compound dissolved in a molten noble metal alloy such that the newly formed surface is readily wetted by the remaining liquid filler material. In many respects, this concept is similar to active metal brazing, except that joining can be conducted in air and the final joint will be resistant to oxidation at high temperature. Potentially, there are a number of metal oxide-noble metal systems that can be considered for RAB, including Ag-CuO, Ag-V2O5, and Pt-Nb2O5. Our current interest is in determining whether the Ag-CuO system is suitable for air brazing functional ceramic-to-metal joints such as those needed in practical electrochemical devices. In a series of studies, the wetting behavior of the Ag-CuO braze was investigated with respect to a number of potential hydrogen separation, oxygen separation, and fuel cell electrolyte membrane materials and heat resistant metal systems, including: alumina, (La0.6Sr0.4)(Co0.2Fe0.8)O3, (La0.8Sr0.2)FeO3, YSZ, fecralloy, and Crofer-22APU. Selected findings from these studies as well as from our work on joint strength and durability during high-temperature exposure testing will be discussed.

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

SciTech Connect

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

The state-of-the-art technologies for the removal of sulfur compounds from Sour Natural Gas (SNG) are not cost-effective when scaled down to approximately 2-5 MMSCFD. At the same time, the SNG Production is increasing at 3-6 TCF/Yr and -78 TCF potential reserves are also sour. Assuming only 3% treatment of this potential SNG market is for small volume processing, the potential U.S. Market is worth $0.14 to $0.28 billion. Therefore, the Gas Processing Industry is seeking novel, cost-effective, environmentally compatible and operator friendly technologies applicable to the small volume producers in the range of less than 1 MMSCFD to - 5 MMSCFD. A novel biological process, BIODESTJLFTM (patent pending), developed at ARCTECH removes H{sub 2}S and other sulfur contaminants that make the Natural Gas Sour. The removal is accomplished by utilizing an adapted mixed microbial culture (consortium). A variety of anaerobic microbial consortia from ARCTECH`s Microbial Culture Collection were grown and tested for removal of H{sub 2}S. One of these consortia, termed SS-11 was found to be particularly effective. Utilizing the SS-11 consortium, a process has been developed on a laboratory-scale to remove sulfur species from Sour Natural Gas at well head production pressures and temperatures. The process has been independently evaluated and found to be promising in effectively removing H{sub 2}S and other sulfur species cost effectively.

Low cost hydrogen/novel membrane technology for hydrogen separation from synthesis gas  

DOE Green Energy (OSTI)

The production of hydrogen from synthesis gas made by gasification of coal is expensive. The separation of hydrogen from synthesis gas is a major cost element in the total process. In this report we describe the results of a program aimed at the development of membranes and membrane modules for the separation and purification of hydrogen from synthesis gas. The performance properties of the developed membranes were used in an economic evaluation of membrane gas separation systems in the coal gasification process. Membranes tested were polyetherimide and a polyamide copolymer. The work began with an examination of the chemical separations required to produce hydrogen from synthesis gas, identification of three specific separations where membranes might be applicable. A range of membrane fabrication techniques and module configurations were investigated to optimize the separation properties of the membrane materials. Parametric data obtained were used to develop the economic comparison of processes incorporating membranes with a base-case system without membranes. The computer calculations for the economic analysis were designed and executed. Finally, we briefly investigated alternative methods of performing the three separations in the production of hydrogen from synthesis gas. The three potential opportunities for membranes in the production of hydrogen from synthesis gas are: (1) separation of hydrogen from nitrogen as the final separation in a air-blown or oxygen-enriched air-blown gasification process, (2) separation of hydrogen from carbon dioxide and hydrogen sulfide to reduce or eliminate the conventional ethanolamine acid gas removal unit, and (3) separation of hydrogen and/or carbon dioxide form carbon monoxide prior to the shift reactor to influence the shift reaction. 28 refs., 54 figs., 40 tabs.

A new technology for producing hydrogen and adjustable ratio syngas from coke oven gas  

Science Conference Proceedings (OSTI)

About 15 billion Nm{sup 3} coke oven gas (COG) is emitted into the air in Shanxi Province in China as air pollutants. It is also a waste of precious chemical resources. In this study, COG was purified respectively by four methods including refrigeration, fiberglass, silica gel, and molecular sieve. Purified COG was separated by a prism membrane into two gas products. One consists mainly of H{sub 2} ({gt}90 vol %) and the other is rich in CH{sub 4} ({gt}60 vol %) with their exact compositions to vary with the membrane separation pressure and outlet gas flow ratio. The gas rich in CH{sub 4} was partially oxidized with oxygen in a high-temperature fixed-bed quartz reactor charged with coke particles of 10 mm size. At 1200-1300{sup o}C, a CH{sub 4} conversion of {gt}99% could be obtained. The H{sub 2}/CO ratio in the synthesis product gas can be adjusted in the range 0.3-1.4, very favorable for further C1 synthesis. 10 refs., 17 figs., 1t ab.

Gas Analysis of Geothermal Fluid Inclusions: A New Technology For Geothermal Exploration  

DOE Green Energy (OSTI)

To increase our knowledge of gaseous species in geothermal systems by fluid inclusion analysis in order to facilitate the use of gas analysis in geothermal exploration. The knowledge of gained by this program can be applied to geothermal exploration, which may expand geothermal production. Knowledge of the gas contents in reservoir fluids can be applied to fluid inclusion gas analysis of drill chip cuttings in a similar fashion as used in the petroleum industry. Thus the results of this project may lower exploration costs both in the initial phase and lower drill hole completion costs. Commercial costs for fluid inclusion analysis done on at 20 feet intervals on chip samples for 10,000 ft oil wells is about $6,000, and the turn around time is a few weeks.

Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Low Temperature X-ray Diffraction Study of Natural Gas Hydrate Samples from the Gulf of Mexico Authors: C.J. Rawn, R. Sassen, S.M. Ulrich, E.A. Payzant, B.C. Chakoumakos, and T.J. Phelps Venue: 6th International Conference on Gas Hydrates, Fairmont Hotel, Vancouver, Canada July 6-10, 2008. http://www.icgh.org/ [external site]. Abstract: Clathrate hydrates of methane and other small alkanes occur widespread as terrestrial components in marine sediments of the continental margins and in permafrost sediments of the arctic. Quantitative study of natural clathrate hydrates is hampered by the difficulty in obtaining pristine samples, particularly from submarine environments. Bringing samples of clathrate hydrate from the seafloor at depths without compromising their integrity is not trivial. Most physical property measurements are based on studies of laboratory-synthesized samples. Here we report x-ray powder diffraction measurements of a natural gas hydrate sample from the Green Canyon, Gulf of Mexico (GOM). The first data were collected in 2002 and revealed ice and structure II gas hydrate. In the subsequent time the sample has been stored in liquid nitrogen. Recently new x-ray powder diffraction data have been collected as a function of temperature. Rietveld refinements on this new data show that there is approximately 50 wt % gas hydrate with structure type II and 50% ice at -140, -130, -115, -100, and -85oC. The Rietveld refinements on the data sets collected at -70 and -55oC show the amount of structure type II hydrate decreasing to approximately 40% and 37%, respectively. The Rietveld refinement of the data set collected at -40oC shows a sharp decrease in the amount of structure type II hydrate to approximately 9%. Rietveld refinements on the data sets collected at -25 and -10oC indicated that the structure type II hydrate is still present at 7 and 3%, respectively

A TECHNICAL, ECONOMIC AND ENVIRONMENTAL ASSESSMENT OF AMINE-BASED CO2 CAPTURE TECHNOLOGY FOR POWER PLANT GREENHOUSE GAS CONTROL  

Science Conference Proceedings (OSTI)

Capture and sequestration of CO{sub 2} from fossil fuel power plants is gaining widespread interest as a potential method of controlling greenhouse gas emissions. Performance and cost models of an amine (MEA)-based CO{sub 2} absorption system for post-combustion flue gas applications have been developed, and integrated with an existing power plant modeling framework that includes multi-pollutant control technologies for other regulated emissions. The integrated model has been applied to study the feasibility and cost of carbon capture and sequestration at both new and existing coal-burning power plants. The cost of carbon avoidance was shown to depend strongly on assumptions about the reference plant design, details of the CO{sub 2} capture system design, interactions with other pollution control systems, and method of CO{sub 2} storage. The CO{sub 2} avoidance cost for retrofit systems was found to be generally higher than for new plants, mainly because of the higher energy penalty resulting from less efficient heat integration, as well as site-specific difficulties typically encountered in retrofit applications. For all cases, a small reduction in CO{sub 2} capture cost was afforded by the SO{sub 2} emission trading credits generated by amine-based capture systems. Efforts are underway to model a broader suite of carbon capture and sequestration technologies for more comprehensive assessments in the context of multi-pollutant environmental management.

ADVANCED FRACTURING TECHNOLOGY FOR TIGHT GAS: AN EAST TEXAS FIELD DEMONSTRATION  

Science Conference Proceedings (OSTI)

The primary objective of this research was to improve completion and fracturing practices in gas reservoirs in marginal plays in the continental United States. The Bossier Play in East Texas, a very active tight gas play, was chosen as the site to develop and test the new strategies for completion and fracturing. Figure 1 provides a general location map for the Dowdy Ranch Field, where the wells involved in this study are located. The Bossier and other tight gas formations in the continental Unites States are marginal plays in that they become uneconomical at gas prices below $2.00 MCF. It was, therefore, imperative that completion and fracturing practices be optimized so that these gas wells remain economically attractive. The economic viability of this play is strongly dependent on the cost and effectiveness of the hydraulic fracturing used in its well completions. Water-fracs consisting of proppant pumped with un-gelled fluid is the type of stimulation used in many low permeability reservoirs in East Texas and throughout the United States. The use of low viscosity Newtonian fluids allows the creation of long narrow fractures in the reservoir, without the excessive height growth that is often seen with cross-linked fluids. These low viscosity fluids have poor proppant transport properties. Pressure transient tests run on several wells that have been water-fractured indicate a long effective fracture length with very low fracture conductivity even when large amounts of proppant are placed in the formation. A modification to the water-frac stimulation design was needed to transport proppant farther out into the fracture. This requires suspending the proppant until the fracture closes without generating excessive fracture height. A review of fracture diagnostic data collected from various wells in different areas (for conventional gel and water-fracs) suggests that effective propped lengths for the fracture treatments are sometimes significantly shorter than those predicted by fracture models. There was no accepted optimal method for conducting hydraulic fracturing in the Bossier. Each operator used a different approach. Anadarko, the most active operator in the play, had tested at least four different kinds of fracture treatments. The ability to arrive at an optimal fracturing program was constrained by the lack of adequate fracture models to simulate the fracturing treatment, and an inability to completely understand the results obtained in previous fracturing programs. This research aimed at a combined theoretical, experimental and field-testing program to improve fracturing practices in the Bossier and other tight gas plays.

Development of a technology of compaction of increased-density parts using gas drainage methods  

Science Conference Proceedings (OSTI)

The influence of the amount and dispersion of technological lubricant (zinc stearate) and solid lubricants (talc, graphite, calcium fluoride) as well as the sintering temperature and time on the physical and mechanical properties of sintered iron is studied. When the stock contains no technological lubricant the porosity of the specimens drops to 5.0-5.2% but their strength is substantially greater than that of SP10 and SP30 steels of the same porosity. The strength of the specimens is highest when the iron powder has the smallest grain size. Solid lubricants in the stock result in the pressed iron-powder parts having poorer mechanical properties, although they do act in part as technological lubricants during compaction. Favorable results may be obtained by complex alloying of the stock, i.e., the simultaneous introduction of several solid lubricants.

Fracture detection, mapping, and analysis of naturally fractured gas reservoirs using seismic technology. Final report, November 1995  

SciTech Connect

Many basins in the Rocky Mountains contain naturally fractured gas reservoirs. Production from these reservoirs is controlled primarily by the shape, orientation and concentration of the natural fractures. The detection of gas filled fractures prior to drilling can, therefore, greatly benefit the field development of the reservoirs. The objective of this project was to test and verify specific seismic methods to detect and characterize fractures in a naturally fractured reservoir. The Upper Green River tight gas reservoir in the Uinta Basin, Northeast Utah was chosen for the project as a suitable reservoir to test the seismic technologies. Knowledge of the structural and stratigraphic geologic setting, the fracture azimuths, and estimates of the local in-situ stress field, were used to guide the acquisition and processing of approximately ten miles of nine-component seismic reflection data and a nine-component Vertical Seismic Profile (VSP). Three sources (compressional P-wave, inline shear S-wave, and cross-line, shear S-wave) were each recorded by 3-component (3C) geophones, to yield a nine-component data set. Evidence of fractures from cores, borehole image logs, outcrop studies, and production data, were integrated with the geophysical data to develop an understanding of how the seismic data relate to the fracture network, individual well production, and ultimately the preferred flow direction in the reservoir. The multi-disciplinary approach employed in this project is viewed as essential to the overall reservoir characterization, due to the interdependency of the above factors.

Lead Slowing Down Spectrometer Research Plans  

Science Conference Proceedings (OSTI)

The MPACT-funded Lead Slowing Down Spectrometry (LSDS) project has been evaluating the feasibility of using LSDS techniques to assay fissile isotopes in used nuclear fuel assemblies. The approach has the potential to provide considerable improvement in the assay of fissile isotopic masses in fuel assemblies compared to other non-destructive techniques in a direct and independent manner. The LSDS collaborations suggests that the next step to in empirically testing the feasibility is to conduct measurements on fresh fuel assemblies to understand investigate self-attenuation and fresh mixed-oxide (MOX) fuel rodlets so we may betterto understand extraction of masses for 235U and 239Pu. While progressing toward these goals, the collaboration also strongly suggests the continued development of enabling technology such as detector development and algorithm development, thatwhich could provide significant performance benefits.

E-Print Network (OSTI)

Pseudomonas cepaciae lipase adsorbed onto non-porous structured fiber supports in the form of woven fabrics, was used to catalyze hydrolysis and transesterification reactions in the gas phase. The enzyme adsorbed onto carbon fiber support exhibited much higher catalytic activity compared to the enzyme immobilized onto glass fiber carrier. The effect of temperature and relative humidity on reactions catalyzed by P. cepaciae lipase adsorbed onto structured fiber carbon support was studied in the gas system. Under the conditions investigated (up to 60 ? C and 80 % relative humidity), the immobilized enzyme showed a high thermostability and could be efficiently used to catalyze hydrolytic and transesterification reactions in continuous mode. Structured fiber supports, with a high specific surface area and a high mechanical resistance, showed a low-pressure drop during the passage of reactants through a reactor. The approach proposed in this study could be suitable for immobilization of a wide variety of enzymes.

Development of monitoring and control technology based on trace gas monitoring. Final report  

DOE Green Energy (OSTI)

Trace gases are generated by many biological reactions. During anaerobic decomposition, trace levels of hydrogen (H{sub 2}) and carbon monoxide (CO) gases are produced. It was shown previously that these trace gases are intrinsically related to the biochemical reactions occurring and, therefore, offer promise for on-line process monitoring and control. This work was designed to test how effectively hydrogen and CO could be to monitor high-rate anaerobic systems that has significant mass transfer and complex hydraulics. An experimental program was designed to examine the behavior of an upflow anaerobic sludge blanket (UASB) reactor system under steady state and in response to organic loading perturbations. The responses of trace gases CO and H{sub 2} were tracked using an on-line, real-time gas-monitoring system linked to a computer-controlled data acquisition package. Data on conventional process parameters such as pH, chemical oxygen demand (COD), volatile fatty acids (VFAs) were concurrently collected. Monitoring of conventional process indicators (i.e., pH, VFA, gas production) and trace gas (H{sub 2} and CO) indicators was conducted using a matrix of nine different steady-state OLRs (4-23 kg COD/m{sup 3} -d) and system HRTs (0.5 to 2.5 days) was performed to determine any correlation among the indicators. Of OLR, HRT, and influent COD, only OLR had any significant influence on the process indicators examined. All parameters except methane increased with increases in OLR; methane decreased with increased OLR. The OLR and gas production rate (GP) were observed to be linearly correlated.

In this and a companion paper (Behseresht, Prodanovic and Bryant) methods are described to test the following hypothesis: the coupling between drainage and fracturing (both induced by pore pressure) determines whether methane gas entering the HSZ is converted completely to hydrate. H A discrete element method (DEM) is presented to model the strong coupling that takes place between the pore fluids and the mechanical behavior of the sediment.
