Coalbed methane resource potential of the Piceance Basin, northwestern Colorado  

SciTech Connect

As predicted, from an evolving coalbed methane producibility model, prolific coalbed methane production is precluded in the Piceance Basin by the absence of coal bed reservoir continuity and dynamic ground-water flow. The best potential for production may lie at the transition zone from hydropressure to hydrocarbon overpressure and/or in conventional traps basinward of where outcrop and subsurface coals are in good reservoir and hydraulic communication. Geologic and hydrologic synergy among tectonic and structural setting, depositional systems and coal distribution, coal rank, gas content, permeability and hydrodynamics are the controls that determine the coalbed methane resource potential of the Piceance Basin. Within the coal-bearing Upper Cretaceous Williams Fork Formation, the prime coalbed methane target, reservoir heterogeneity and thrust faults cause coal beds along the Grand Hogback and in the subsurface to be in modest to poor reservoir and hydraulic communication, restricting meteoric ground water recharge and basinward flow. Total subsurface coalbed methane resources are still estimated to be approximately 99 Tcf (3.09 Tm{sup 3}), although coalbed methane resource estimates range between 80 (2.49 Tm{sup 3}) and 136 Tcf (4.24 Tm{sup 3}), depending on the calculation method used. To explore for high gas contents or fully gas-saturated coals and consequent high productivity in the Piceance Basin, improved geologic and completion technologies including exploration and development for migrated conventionally and hydrodynamically trapped gases, in-situ generated secondary biogenic gases, and solution gases will be required.

Geologic evaluation of critical production parameters for coalbed methane resources. Part 1. San Juan Basin. Annual report, August 1988-July 1989  

SciTech Connect

In the San Juan Basin, Fruitland Formation coal seams contain an estimated 43 to 49 Tcf of methane. With more than 500 producing coalbed methane wells and approximately 1,000 wells scheduled for drilling in 1990, the basin is one of the most active areas of coalbed methane exploration and production in the United States. Among the most important geologic factors affecting the occurrence and producibility of coalbed methane are depositional setting, structural attitude and fracturing of the coal, and regional hydraulic setting. In the second year of the study, the Bureau of Economic Geology evaluated the depositional setting and structure of Fruitland coal seams, which are both source rocks and reservoirs for coalbed methane, throughout the basin. The report summarizes the regional tectonic setting of the San Juan Basin; describes the Cretaceous stratigraphy, structure, and basin evolution; relates these factors to Fruitland coal and coalbed methane occurrence; describes studies of lineaments, fractures, and cleats; presents hydrodynamic controls on the producibility of coalbed methane from the Fruitland Formation; summarizes production from the Fruitland Formation; and evaluates geologic and hydrologic controls on coalbed methane producibility.

Alaska coal geology, resources, and coalbed methane potential  

SciTech Connect

Estimated Alaska coal resources are largely in Cretaceous and Tertiary rocks distributed in three major provinces, Northern Alaska-Slope, Central Alaska-Nenana, and Southern Alaska-Cook Inlet. Cretaceous resources, predominantly bituminous coal and lignite, are in the Northern Alaska-Slope coal province. Most of the Tertiary resources, mainly lignite to subbituminous coal with minor amounts of bituminous and semianthracite coals, are in the other two provinces. The combined measured, indicated, inferred, and hypothetical coal resources in the three areas are estimated to be 5,526 billion short tons (5,012 billion metric tons), which constitutes about 87 percent of Alaska's coal and surpasses the total coal resources of the conterminous United States by 40 percent. Coal mining has been intermittent in the Central Alaskan-Nenana and Southern Alaska-Cook Inlet coal provinces, with only a small fraction of the identified coal resource having been produced from some dozen underground and strip mines. Alaskan coals have a lower sulfur content (averaging 0.3 percent) than most coals in the conterminous United States and are within or below the minimum sulfur value mandated by the 1990 Clean Air Act amendments. Another untapped potential resource is coalbed methane estimated to total 1,000 trillion cubic feet (28 trillion cubic meters).

Challenges in assessment, management and development of coalbed methane resources in the Powder River Basin, Wyoming  

SciTech Connect

Coalbed methane development in the Powder River Basin has accelerated rapidly since the mid-1990's. forecasts of coalbed methane (CBM) production and development made during the late 1980's and early 1990's have proven to be distinctly unreliable. Estimates of gas in place and recoverable reserves have also varied widely. This lack of reliable data creates challenges in resource assessment, management and development for public resource management agencies and the CBM operators. These challenges include a variety of complex technical, legal and resource management-related issues. The Bureau of Land Management's Wyoming Reservoir Management Group (WRMG) and US Geological Survey (USGS), with the cooperation and assistance of CBM operators and other interested parties have initiated cooperative studies to address some of these issues. This paper presents results of those studies to date and outlines the agencies' goals and accomplishments expected at the studies' conclusion.

Preliminary resource assessment of coalbed methane in the United States  

SciTech Connect

Preliminary results of the DOE Methane Recovery from Coalbeds Project reveal that many of the coal regions in the United States have significant volumes of coalbed methane. These results show that 45 cooperative wells drilled to date have helped to update the estimates of methane in the various coal regions. The most promising coal region is in the Green River Basin where preliminary estimates show that the methane potential may be over 23 trillion cubic feet. Another area of considerable interest is in the Arkoma Basin where the methane content of coal samples ranged from 200 to 400 cubic feet per ton (cf/ton) of coal. The methane estimte in this basin is between 1.6 to 3.6 trillion cubic feet. The Piceance Creek coal region is an area presently generating considerable interest and industry activity. The methane content of the coal samples extracted from this basin averaged over 100 cf/ton. The Northern Appalachian region also shows considerable promise.

Coordinated studies in support of hydraulic fracturing of coalbed methane. Annual report, January 1993-April 1994  

SciTech Connect

The production of natural gas from coal typically requires stimulation in the form of hydraulic fracturing and, more recently, cavity completions. The results of hydraulic fracturing treatments have ranged from extremely successful to less than satisfactory. The purpose of this work is to characterize common and potential fracturing fluids in terms of coal-fluid interactions to identify reasons for less than satisfactory performance and to ultimately devise alternative fluids and treatment procedures to optimize production following hydraulic fracturing. The laboratory data reported herein has proven helpful in designing improved hydraulic fracturing treatments and remedial treatments in the Black Warrior Basin. Acid inhibitors, scale inhibitors, additives to improve coal relative permeability to gas, and non-damaging polymer systems for hydraulic fracturing have been screened in coal damage tests. The optimum conditions for creating field-like foams in the laboratory have been explored. Tests have been run to identify minimum polymer and surfactant concentrations for applications of foam in coal. The roll of 100 mesh sand in controlling leakoff and impairing conductivity in coal has been investigated. The leakoff and proppant transport of fluids with breaker has been investigated and recommendations have been made for breaker application to minimize damage potential in coal. A data base called COAL`S has been created in Paradox (trademark) for Windows to catalogue coalbed methane activities in the Black Warrior and San Juan Basins.

Assessment of undiscovered carboniferous coal-bed gas resources of the Appalachian Basin and Black Warrior Basin Provinces, 2002  

SciTech Connect

Coalbed methane (CBM) occurs in coal beds of Mississippian and Pennsylvanian (Carboniferous) age in the Appalachian basin, which extends almost continuously from New York to Alabama. In general, the basin includes three structural subbasins: the Dunkard basin in Pennsylvania, Ohio, and northern West Virginia; the Pocahontas basin in southern West Virginia, eastern Kentucky, and southwestern Virginia; and the Black Warrior basin in Alabama and Mississippi. For assessment purposes, the Appalachian basin was divided into two assessment provinces: the Appalachian Basin Province from New York to Alabama, and the Black Warrior Basin Province in Alabama and Mississippi. By far, most of the coalbed methane produced in the entire Appalachian basin has come from the Black Warrior Basin Province. 8 refs., 1 fig., 1 tab.

GEOLOGIC SCREENING CRITERIA FOR SEQUESTRATION OF CO2 IN COAL: QUANTIFYING POTENTIAL OF THE BLACK WARRIOR COALBED METHANE FAIRWAY, ALABAMA  

SciTech Connect

Sequestration of CO{sub 2} in coal has potential benefits for reducing greenhouse gas emissions from the highly industrialized Carboniferous coal basins of North America and Europe and for enhancing coalbed methane recovery. Hence, enhanced coalbed methane recovery operations provide a basis for a market-based environmental solution in which the cost of sequestration is offset by the production and sale of natural gas. The Black Warrior foreland basin of west-central Alabama contains the only mature coalbed methane production fairway in eastern North America, and data from this basin provide an excellent basis for quantifying the carbon sequestration potential of coal and for identifying the geologic screening criteria required to select sites for the demonstration and commercialization of carbon sequestration technology. Coalbed methane reservoirs in the upper Pottsville Formation of the Black Warrior basin are extremely heterogeneous, and this heterogeneity must be considered to screen areas for the application of CO{sub 2} sequestration and enhanced coalbed methane recovery technology. Major screening factors include stratigraphy, geologic structure, geothermics, hydrogeology, coal quality, sorption capacity, technology, and infrastructure. Applying the screening model to the Black Warrior basin indicates that geologic structure, water chemistry, and the distribution of coal mines and reserves are the principal determinants of where CO{sub 2} can be sequestered. By comparison, coal thickness, temperature-pressure conditions, and coal quality are the key determinants of sequestration capacity and unswept coalbed methane resources. Results of this investigation indicate that the potential for CO{sub 2} sequestration and enhanced coalbed methane recovery in the Black Warrior basin is substantial and can result in significant reduction of greenhouse gas emissions while increasing natural gas reserves. Coal-fired power plants serving the Black Warrior basin in Alabama emit approximately 31 MMst (2.4 Tcf) of CO{sub 2} annually. The total sequestration capacity of the Black Warrior coalbed methane fairway at 350 psi is about 189 MMst (14.9 Tcf), which is equivalent to 6.1 years of greenhouse gas emissions from the coal-fired power plants. Applying the geologic screening model indicates that significant parts of the coalbed methane fairway are not accessible because of fault zones, coal mines, coal reserves, and formation water with TDS content less than 3,000 mg/L. Excluding these areas leaves a sequestration potential of 60 MMst (4.7 Tcf), which is equivalent to 1.9 years of emissions. Therefore, if about10 percent of the flue gas stream from nearby power plants is dedicated to enhanced coalbed methane recovery, a meaningful reduction of CO{sub 2} emissions can be realized for nearly two decades. If the fresh-water restriction were removed for the purposes of CO{sub 2} sequestration, an additional 10 MMst (0.9 Tcf) of CO{sub 2} could feasibly be sequestered. The amount of unswept coalbed methane in the fairway is estimated to be 1.49 Tcf at a pressure of 50 psi. Applying the screening model results in an accessible unswept gas resource of 0.44 Tcf. Removal of the fresh-water restriction would elevate this number to 0.57 Tcf. If a recovery factor of 80 percent can be realized, then enhanced recovery activities can result in an 18 percent expansion of coalbed methane reserves in the Black Warrior basin.

Enhanced coalbed methane recovery  

SciTech Connect

The recovery of coalbed methane can be enhanced by injecting CO{sub 2} in the coal seam at supercritical conditions. Through an in situ adsorption/desorption process the displaced methane is produced and the adsorbed CO{sub 2} is permanently stored. This is called enhanced coalbed methane recovery (ECBM) and it is a technique under investigation as a possible approach to the geological storage of CO{sub 2} in a carbon dioxide capture and storage system. This work reviews the state of the art on fundamental and practical aspects of the technology and summarizes the results of ECBM field tests. These prove the feasibility of ECBM recovery and highlight substantial opportunities for interdisciplinary research at the interface between earth sciences and chemical engineering.

Water production in enhanced coalbed methane operations  

Science Journals Connector (OSTI)

Coalbed methane (CBM) formations provides a considerable amount of the US natural gas production and have the potential of storing significant amounts of carbon dioxide (CO2) through enhanced gas recovery operations. Enhanced coalbed methane (ECBM) recovery by injection of CO2 or a mixture of CO2 and nitrogen (N2) has been proven to recover additional natural gas resources. However, since coalbeds are normally saturated with water and can be in communication with an aquifer, a large amount of water is often co-produced during the natural gas extraction. The conventional approach for CBM production relies on the reduction of the gas partial pressure in the coal seam. This can be accomplished by either pumping the formation water to the surface and/or by injecting gases such as N2 and CO2. Disposal of the produced water is an environmental challenge as harmful impurities must be removed by appropriate purification techniques. Consequently, a reduction of water production in CBM operations is desirable. In this paper we present a numerical investigation of the potential reduction in water production during ECBM operations that are commonly used to increase methane (CH4) recovery. We use a three-dimensional coalbed model with an aquifer located at the bottom to investigate the amounts of gas and water produced in ECBM operations per volume of coal seam as a function of aquifer strength and sorption characteristics including sorption induced strain. The amount of gas/water that is produced varies significantly depending on the aquifer strength and injection gas composition. We demonstrate that injection of CO2 and/or N2 in some settings reduces the water handling problem substantially. CBM is an important worldwide energy source with a large number of formations being excellent candidates for ECBM recovery processes. Our analysis of the interplay between coal characteristics, aquifer support and the resultant behavior in terms of gas/water production provides valuable input for optimization of future planning and operations.

Integrated process for coalbed brine and methane disposal  

SciTech Connect

This paper describes a technology and project to demonstrate and commercialize a brine disposal process for converting the brine stream of a coalbed gas producing site into clean water for agricultural use and dry solids that can be recycled for industrial consumption. The process also utilizes coalbed methane (CBM) released from coal mining for the combustion process thereby substantially reducing the potential for methane emissions to the atmosphere. The technology is ideally suited for the treatment and disposal of produced brines generated from the development of coal mines and coalbed methane resources worldwide. Over the next 10 to 15 years, market potential for brine elimination equipment and services is estimated to be in the range of $1 billion.

Uncertainty about how plant and soil processes respond to wet and dry periods at different times in the growing season is a barrier to understanding how changing rainfall patterns will affect ecosystem function in annual grasslands. We used mesocosm systems to test the sensitivity to mid- and late-season dry periods of twenty response variables related to nitrogen, carbon, and water cycling in Avena barbata monocultures. We compared the responses of individual variables and of grassland systems under low and high cumulative rain treatments and between two contrasting soil types.

INEEL Cultural Resource Management Program Annual Report - 2004  

SciTech Connect

As a federal agency, the U.S. Department of Energy has been directed by Congress, the U.S. president, and the American public to provide leadership in the preservation of prehistoric, historic, and other cultural resources on the lands it administers. This mandate to preserve cultural resources in a spirit of stewardship for the future is outlined in various federal preservation laws, regulations, and guidelines such as the National Historic Preservation Act, the Archaeological Resources Protection Act, and the National Environmental Policy Act. The Idaho National Engineering and Environmental Laboratory Site is located in southeastern Idaho, and is home to vast numbers and a wide variety of important cultural resources representing at least 13,000-year span of human occupation in the region. These resources are nonrenewable, bear valuable physical and intangible legacies, and yield important information about the past, present, and perhaps the future. There are special challenges associated with balancing the preservation of these resources with the management and ongoing operation of an active scientific laboratory, while also cleaning up the waste left by past programs and processes. The Department of Energy Idaho Operations Office has administrative responsibility for most of the Site, excluding lands and resources managed by the Naval Reactors Facility and (in 2004) Argonne National Laboratory-West. The Department of Energy is committed to a cultural resource program that accepts these challenges in a manner reflecting both the spirit and intent of the legislative requirements. This annual report is an overview of Cultural Resource Management Program activities conducted during Fiscal Year 2004 and is intended to be both informative to external stakeholders and to serve as a planning tool for future cultural resource management work to be conducted on the Site.

Coalbed methane potential of the Greater Green River, Piceance, Powder River, and Raton Basins. Topical report, January 1991-July 1991  

SciTech Connect

Coalbed methane potential of the Greater Green River, Piceance, Powder River, and Raton Basins was evaluated in the context of geologic and hydrologic characteristics identified in the San Juan Basin, the nation's leading coalbed methane producing basin. The major comparative criteria were (1) coalbed methane resources, (2) geologic and hydrologic factors that predict areas of high gas producibility and high coalbed reservoir permeability, and (3) coalbed thermal maturity. The technical criteria were expanded to include structure, depositional systems, and data base and then combined with economic criteria (production, industry activity, and pipeline availability) to evaluate the coalbed methane potential of the basins. The Greater Green River and Piceance Basins have primary potential to make a significant near-term contribution to the nation's gas supply. These basins have large gas resources, high-rank coals, high gas contents, and established coalbed methane production. The Greater Green River Basin has numerous coalbed methane targets, good coal-seam permeability, and extensive hydrologic areas favorable for production. The Powder River and Raton Basins were judged to have secondary potential. Coal beds in the Powder River Basin are thermally immature and produce large volumes of water; the Raton Basin has a poor data base and has no gas pipeline infrastructure. Low production and minimal industry activity further limit the near-term potential of the Raton Basin. However, if economic criteria are discounted and only major technical criteria are considered, the Greater Green River and Raton Basins are assigned primary potential. The Raton Basin's shallow, thermally mature coal beds of good permeability are attractive coalbed methane targets, but low coal-seam permeability limits the coalbed methane potential of the Piceance Basin.

A study on coalbed methane reserve of Shanxi: Hedong coalfield reserve and its utilization  

SciTech Connect

Coalbed gas, i.e. coalbed methane, is considered an unconventional gas, formed during coal accumulation and preserved in coal seams. In the past, coalbed gas was considered a major hazard factor to the safety of mining and caused countless explosive events and great losses to the enterprises and even to the country. Early in 1960s and 70s, it was recognized that coalbed gas could be utilized as an energy resource and collected through tunnels in China. In 1995, the output of tunnel gas reached 500Mm{sup 3}, however, surface pumping is still at its beginning stage, test and appraisal; so far, no commercial development is being carried out in China. Hedong coalfield, situated in the west of Shanxi province and bordered by the Yellow River in the northwest and outcrop seams in the southeast, is 540km long (N-S) and 10--40 km wide (E-W) and covers an area of 17,000 km{sup 2} across 13 counties of Xinzou, Luliang, Linfen and Yuncheng prefectures. It is the No. 2 coalfield in Shanxi province and the well-known base of excellent coking coal and power coal in China. Hedong coalfield is not only rich in coal resource, but also in coalbed methane. This paper describes the geology of the coalfield (including structure, magmatic activity, coal seams and coal grade); the regularity of coalbed methane occurrence in the Hedong coalfield; the calculation of coalbed methane resource; and the use of coalbed methane for motor fuels and chemicals production. The total resource is 1468.93Gm{sup 3}. The production of motor fuels can be realized by the following processes: (a) synthetic methanol as substitute of gasoline; (b) F-T synthesis for synthetic gasoline and diesel oil; (c) Compressed natural gas as motor fuel; and (d) Liquefied natural gas as motor fuel. The production of organic chemicals is suggested with the following technology: (a) Two-stage steam reforming to convert methane to synthetic gas various organic chemicals can be produced therefrom; (b) Partial oxidation of methane to produce synthesis gas and acetylene; (c) Coalbed methane to produce hydrogen cyanide and chloromethanes; and (d) Coalbed methane to produce acrylonitrile, acetylene, ethylene, propylene and butylenes.

Recovery economics of coalbed methane and cost implications of pipeline hookup  

SciTech Connect

For Appalachian coal mines, the totaled methane emission rates exceed 180 MMCF/D, with active mines pushing deeper into virgin seams having higher relative gas contents. While most of this gas currently is vented into the atmosphere to prevent gas-related explosions, the technology exists to develop this valuable gas resource either in conjunction with mining or independently. In 1977, the U.S. Department of Energy (DOE) began the Methane Recovery from Coalbeds Project (MRCP) to characterize and help encourage utilization of this resource. Since the project inception, TRW has been involved in the collection and analysis of data, and is in the process of forming a coherent picture of the coalbed methane resource potential for the entire Appalachian region. Preliminary analysis indicates an estimated in-place coalbed methane resource in the Appalachian Basin of up to 150 TCF. Eastern coal operators are beginning to better understand the production potential of coalbed methane. In Buchanan County, Virginia, the Island Creek Coal Company produced up to 434 MCF/d from 12 horizontal boreholes drilled into the mine face. In Alabama, U.S. Steel's mines recently began commercial production and sold 25 MMCF of pipeline quality gas in December of 1981. This study examines the recovery economics of coalbed methane, and specifically addresses the cost implications of pipeline hook-up. An analysis which addresses the size of a project, pipeline construction costs, and anticipated contract gas price helps determine an economical project-topipeline hook-up distance.

SEQUESTERING CARBON DIOXIDE IN COALBEDS  

SciTech Connect

The authors' long-term goal is to develop accurate prediction methods for describing the adsorption behavior of gas mixtures on solid adsorbents over complete ranges of temperature, pressure, and adsorbent types. The originally-stated, major objectives of the current project are to: (1) measure the adsorption behavior of pure CO{sub 2}, methane, nitrogen, and their binary and ternary mixtures on several selected coals having different properties at temperatures and pressures applicable to the particular coals being studied, (2) generalize the adsorption results in terms of appropriate properties of the coals to facilitate estimation of adsorption behavior for coals other than those studied experimentally, (3) delineate the sensitivity of the competitive adsorption of CO{sub 2}, methane, and nitrogen to the specific characteristics of the coal on which they are adsorbed; establish the major differences (if any) in the nature of this competitive adsorption on different coals, and (4) test and/or develop theoretically-based mathematical models to represent accurately the adsorption behavior of mixtures of the type for which measurements are made. As this project developed, an important additional objective was added to the above original list. Namely, we were encouraged to interact with industry and/or governmental agencies to utilize our expertise to advance the state of the art in coalbed adsorption science and technology. As a result of this additional objective, we participated with the Department of Energy and industry in the measurement and analysis of adsorption behavior as part of two distinct investigations. These include (a) Advanced Resources International (ARI) DOE Project DE-FC26-00NT40924, ''Adsorption of Pure Methane, Nitrogen, and Carbon Dioxide and Their Mixtures on Wet Tiffany Coal'', and (b) the DOE-NETL Project, ''Round Robin: CO{sub 2} Adsorption on Selected Coals''. These activities, contributing directly to the DOE projects listed above, also provided direct synergism with the original goals of our work. Specific accomplishments of this project are summarized below in three broad categories: experimentation, model development, and coal characterization.

Appalachian basin coal-bed methane: Elephant or flea  

SciTech Connect

Historically, interest in the Appalachian basin coal-bed methane resource extends at least over the last 50 years. The Northern and Central Appalachian basins are estimated to contain 61 tcf and 5 tcf of coal-bed methane gas, respectively. Development of this resource has not kept pace with that of other basins, such as the Black Warrior basin of Alabama of the San Juan basin of northern New Mexico and Colorado. Without the benefit of modern completion, stimulation, and production technology, some older Appalachian basin coal-bed methane wells were reported to have produced in excess of 150 used here to characterize some past projects and their results. This work is not intended to comprise a comprehensive survey of all Appalachian basin projects, but rather to provide background information from which to proceed for those who may be interested in doing so. Several constraints to the development of this resource have been identified, including conflicting legal rights of ownership of the gas produced from the coal seams when coal and conventional oil and gas rights are controlled by separate parties. In addition, large leaseholds have been difficult to acquire and finding costs have been high. However, the threshold of minimum economic production may be relatively low when compared with other areas, because low-pressures pipelines are available and gas prices are among the highest in the nation. Interest in the commercial development of the resource seems to be on the increase with several projects currently active and more reported to be planned for the near future.

Utah coalbed gas exploration poised for growth  

SciTech Connect

Coalbed methane production in eastern Utah is growing despite a relaxed pace of exploratory drilling. Leasing has been active the past 2 years, but a delay in issuance of a federal environmental impact statement could retard drilling. Only 19 new wells began producing coalbed gas during 1995, but gas production increased from existing wells as dewatering progressed. The US Bureau of Land Management will allow limited exploration but no field development on federal lands until the EIS is completed, possibly as early as this month. The paper discusses production of coalbed methane in Utah.

Coalbed methane: A partial solution to Indonesia`s growing energy problems  

SciTech Connect

Indonesia contains the largest resources of coal in Southeast Asia. Indonesian scientists estimate that the in-place coalbed methane resource in 16 onshore basins is about 213 Tcf ({approximately}6 Tcm). This volume is approximately double Indonesia`s current reserves of natural gas. Indonesia is a rapidly industrializing nation of 186 million people, of which 111 million live in Java and 38 million in Sumatra. As industrialization progresses from the present low level, the growth in energy demand will be very rapid. Indonesia`s domestic gas demand is expected to increase form 1.6 Bcf/d (0.05 Bcm/d) in 1991 to 5.7 Bcf/d (0.2 Bcm/d) in 2021. Because the major gas resources of East Kalimantan, North Sumatra, and Natuna are so remote from the main consuming area in northwest Java and are dedicated for export by virtue of the national energy policy, the need is becoming urgent to develop new resources of natural gas, including coalbed methane, for the domestic market. Due to the high geothermal gradient, the coal deposits in the back-arc basins of Sumatra and Java are expected to be of higher than normal rank at depths favorable for coalbed methane production. The oil- and gas-productive Jatibarang sub-basin in northwest Java, with estimated in-place resources of coalbed methane in excess of 20 Tcf (0.6 Tcm), is considered to be the most prospective area in Indonesia for the near-term development of coalbed methane. This area includes Jakarta and vicinity, the most populous and most heavily industrialized part of Indonesia.

Research and Development Concerning Coalbed Natural Gas  

SciTech Connect

The Powder River Basin in northeastern Wyoming is one of the most active areas of coalbed natural gas (CBNG) development in the western United States. This resource provides clean energy but raises environmental concerns. Primary among these is the disposal of water that is co-produced with the gas during depressurization of the coal seam. Beginning with a few producing wells in Wyoming's Powder River Basin (PRB) in 1987, CBNG well numbers in this area increased to over 13,600 in 2004, with projected growth to 20,900 producing wells in the PRB by 2010. CBNG development is continuing apace since 2004, and CBNG is now being produced or evaluated in four other Wyoming coal basins in addition to the PRB, with roughly 3500-4000 new CBNG wells permitted statewide each year since 2004. This is clearly a very valuable source of clean fuel for the nation, and for Wyoming the economic benefits are substantial. For instance, in 2003 alone the total value of Wyoming CBNG production was about $1.5 billion, with tax and royalty income of about $90 million to counties, $140 million to the state, and $27 million to the federal government. In Wyoming, cumulative CBNG water production from 1987 through December 2004 was just over 380,000 acre-feet (2.9 billion barrels), while producing almost 1.5 trillion cubic feet (tcf) of CBNG gas statewide. Annual Wyoming CBNG water production in 2003 was 74,457 acre-feet (577 million barrels). Total production of CBNG water across all Wyoming coal fields could total roughly 7 million acre-feet (55.5 billion barrels), if all of the recoverable CBNG in the projected reserves of 31.7 tcf were produced over the coming decades. Pumping water from coals to produce CBNG has been designated a beneficial water use by the Wyoming State Engineer's Office (SEO), though recently the SEO has limited this beneficial use designation by requiring a certain gas/water production ratio. In the eastern part of the PRB where CBNG water is generally of good quality, most of it is discharged to surface drainages or to soil (for irrigation). CBNG water quality generally declines when moving from the Cheyenne River drainage northwestward to the Belle Fourche, Little Powder, and Powder River drainages and in the central and western part of the PRB, most CBNG water goes to evaporation-infiltration ponds or is discharged directly to surface drainages. Concerns center on the salinity of the water, usually measured as total dissolved solids (TDS), or electrical conductivity (EC) and sodium adsorption ratio (SAR). Other management options currently in use include injection, managed irrigation (with additives to mitigate the effects of high salinity), atomization, and treatment by reverse osmosis or ion exchange. A key water quality issue is the cumulative effect of numerous CBNG water discharges on the overall water quality of basin streams. This leads to one of the most contentious issues in CBNG development in Wyoming's PRB: Montana's concern about the potential downstream effects of water quality degradation on rivers flowing north into Montana. Many of the benefits and costs associated with CBNG development have been debated, but dealing with CBNG water quantity and quality arguably has been the most difficult of all the issues. Given the importance of these issues for continued development of CBNG resources in Wyoming and elsewhere, the DOE-NETL funded project presented here focuses on CBNG co-produced water management. The research was organized around nine separate, but interrelated, technical project tasks and one administrative task (Task 1). The nine technical project tasks were pursued by separate research teams at the University of Wyoming, but all nine tasks were coordinated to the extent possible in order to maximize information gained about CBNG co-produced waters. In addition to project management in Task 1, the key research tasks included: (2) estimating groundwater recharge rates in the PRB; (3) groundwater contamination of trace elements from CBNG disposal ponds; (4) use of environmental tracers in assessing wate

Trends in water quality variability for coalbed methane produced water  

Science Journals Connector (OSTI)

Abstract Energy production from unconventional natural gas resources, such as coalbed methane, has the potential to generate significant water quantities for use in water-stressed areas to augment existing water supplies. Coalbed methane (CBM) produced water is generated from shallower formations than traditional oil and gas resources where water quality may be influenced by fresh water supplies in the area. Variability in produced water quality between wells and across geologic basins must be characterized in order to categorize water types appropriate for beneficial use. Principal component analysis (PCA) was applied to a composite geochemical database to identify indicators of variability in water composition and quality. Component analysis revealed that water quality indicators of variability were related to: (i) aquifer recharge that dilutes constituent concentrations (37%), (ii) dissolution of soluble aquifer minerals such as sodium and exchange of calcium and magnesium (13.8%), and (iii) coal depositional environment influence on chloride and trace metal fractions (14% of variability). Ternary relationships between Na–Cl–HCO3 and Na–Ca–Mg correlate to marine influence in the coal depositional environment and well proximity to recharge, respectively. Relationships identified in this study highlight water quality compositions with opportunities for beneficial use.

Powder River Basin coalbed methane: The USGS role in investigating this ultimate clean coal by-product  

SciTech Connect

For the past few decades, the Fort Union Formation in the Powder River Basin has supplied the Nation with comparatively clean low ash and low sulfur coal. However, within the past few years, coalbed methane from the same Fort Union coal has become an important energy by-product. The recently completed US Geological Survey coal resource assessment of the Fort Union coal beds and zones in the northern Rocky Mountains and Great Plains (Fort Union Coal Assessment Team, 1999) has added useful information to coalbed methane exploration and development in the Powder River Basin in Wyoming and Montana. Coalbed methane exploration and development in the Powder River Basin has rapidly accelerated in the past three years. During this time more than 800 wells have been drilled and recent operator forecasts projected more than 5,000 additional wells to be drilled over the next few years. Development of shallow (less than 1,000 ft. deep) Fort Union coal-bed methane is confined to Campbell and Sheridan Counties, Wyoming, and Big Horn County, Montana. The purpose of this paper is to report on the US Geological Survey's role on a cooperative coalbed methane project with the US Bureau of Land Management (BLM), Wyoming Reservoir Management Group and several gas operators. This paper will also discuss the methodology that the USGS and the BLM will be utilizing for analysis and evaluation of coalbed methane reservoirs in the Powder River Basin. The USGS and BLM need additional information of coalbed methane reservoirs to accomplish their respective resource evaluation and management missions.

Chapter 10 - Coal and Coalbed Gas: Outlook  

Science Journals Connector (OSTI)

Abstract The future of coal and coalbed gas future is intertwined as source and reservoir rocks. Coal generates coalbed gas during coalification (e.g. thermogenic gas) and methanogenesis (biogenic gas). These gas types occur as singular and mixed accumulations. Accumulation of biogenic coalbed gas has received worldwide research and development interests on sustaining production. The new coal-to-biogenic coalbed gas technology centers on stimulating indigenous microbes in coal and associated groundwater with bioengineered nutrients and amendments to “farm” gas from abandoned wells and non-gas-producing coals. Coal mainly as a basic fuel for electric power generation since the Industrial Revolution continues to be utilized despite environmental concerns. The outlook of coal is dimmed in the United States where natural gas has replaced power generation. However, in Asia and Europe continued economic growth is going to be fueled by coal and coalbed gas as liquefied natural gas will rely on combustion from more efficient, high-temperature power plants in the future.

Resource assessment. Annual report, October 1, 1979-September 30, 1980  

SciTech Connect

The Department of Energy is developing a computer-based catalog of properties of petroleum reservoirs to enable the continuous assessment of the country's resource for EOR applicability. The development of improved methods for determination of residual oil saturation is an important part of the assessment. Better diagnostic tools for characterizing the reservoir will improve the ability to predict the usefulness of EOR techniques. And as additional data on field experiments with EOR methods can be added to the data bank, both the development of criteria to select an EOR method and the predictability of its results will improve. This section of the Petroleum Research Report contains 3 papers on resource characterization, 15 papers on reservoir evaluation, 3 papers on environmental technology, 4 papers on improved drilling technology, 3 papers on extraction technology, and 2 papers on the tar sands.

The potential for coalbed gas exploration and production in the Greater Green River Basin, southwest Wyoming and northwest Colorado  

SciTech Connect

Coalbed gas is an important source of natural gas in the United States. In 1993, approximately 740 BCF of coalbed gas was produced in the United States, or about 4.2% of the nation`s total gas production. Nearly 96% of this coalbed gas is produced from just two basins, the San Juan (615.7 BCF; gas in place 84 TCF) and Black Warrior (105 BCF; gas in place 20 TCF), and current production represents only a fraction of the nation`s estimated 675 TCF of in-place coalbed gas. Coal beds in the Greater Green River Basin in southwest Wyoming and northwest Colorado hold almost half of the gas in place (314 TCF) and are an important source of gas for low-permeability Almond sandstones. Because total gas in place in the Greater Green River Basin is reported to exceed 3,000 TCF (Law et al., 1989), the basin may substantially increase the domestic gas resource base. Therefore, through integrated geologic and hydrologic studies, the coalbed gas potential of the basin was assessed where tectonic, structural, and depositional setting, coal distribution and rank, gas content, coal permeability, and ground-water flow are critical controls on coalbed gas producibility. Synergism between these geologic and hydrologic controls determines gas productivity. High productivity is governed by (1) thick, laterally continuous coals of high thermal maturity, (2) basinward flow of ground water through fractured and permeable coals, down the coal rank gradient toward no-flow boundaries oriented perpendicular to the regional flow direction, and (3) conventional trapping of gas along those boundaries to provide additional sources of gas beyond that sorbed on the coal surface.

Demonstration projects for coalbed methane and Devonian shale gas: Final report. [None  

SciTech Connect

In 1979, the US Department of Energy provided the American Public Gas Association (APGA) with a grant to demonstrate the feasibility of bringing unconventional gas such as methane produced from coalbeds or Devonian Shale directly into publicly owned utility system distribution lines. In conjunction with this grant, a seven-year program was initiated where a total of sixteen wells were drilled for the purpose of providing this untapped resource to communities who distribute natural gas. While coalbed degasification ahead of coal mining was already a reality in several parts of the country, the APGA demonstration program was aimed at actual consumer use of the gas. Emphasis was therefore placed on degasification of coals with high methane gas content and on utilization of conventional oil field techniques. 13 figs.

Coalbed Methane Production and Reclamation Field Tour Coalbed Methane Production and Reclamation Field Tour Coalbed Methane Production and Reclamation Field Tour Author: John Wheaton, Montana Tech of the University of Montana, Butte, MT. Venue: The tour will be conducted starting in Gillette, WY, and extend along the northern Powder River Basin, on June 3, 2007, under the auspices of the American Society for Mining and Reclamation (http://ces.ca.uky.edu/asmr/ [external site]). Abstract: This field tour will emphasize successful reclamation in an alternative type of coal industry in the Powder River Basin: coalbed methane. The tour will leave Gillette, WY, at 7:30 a.m., Sunday, June 3, 2007, and travel to Sheridan, WY, and back, touring coalbed methane production areas. Stops will include active drilling and producing areas to learn about the footprint and approach to development of coalbed methane. Reclamation includes drilling pads and linear trenching for water and gas pipelines. Produced-water management is a major expense and concern. Among the water management options we plan to see are stock-watering facilities, infiltration ponds, irrigation sites, and water treatment facilities. A landowner will join us and be able to answer questions from the ranching perspective for part of the tour. Lunches are included in the price of the tour.

Water Management Strategies for Improved Coalbed Methane Production in the Black Warrior Basin  

SciTech Connect

The modern coalbed methane industry was born in the Black Warrior Basin of Alabama and has to date produced more than 2.6 trillion cubic feet of gas and 1.6 billion barrels of water. The coalbed gas industry in this area is dependent on instream disposal of co-produced water, which ranges from nearly potable sodium-bicarbonate water to hypersaline sodium-chloride water. This study employed diverse analytical methods to characterize water chemistry in light of the regional geologic framework and to evaluate the full range of water management options for the Black Warrior coalbed methane industry. Results reveal strong interrelationships among regional geology, water chemistry, and gas chemistry. Coalbed methane is produced from multiple coal seams in Pennsylvanian-age strata of the Pottsville Coal Interval, in which water chemistry is influenced by a structurally controlled meteoric recharge area along the southeastern margin of the basin. The most important constituents of concern in the produced water include chlorides, ammonia compounds, and organic substances. Regional mapping and statistical analysis indicate that the concentrations of most ionic compounds, metallic substances, and nonmetallic substances correlate with total dissolved solids and chlorides. Gas is effectively produced at pipeline quality, and the only significant impurity is N{sub 2}. Geochemical analysis indicates that the gas is of mixed thermogenic-biogenic origin. Stable isotopic analysis of produced gas and calcite vein fills indicates that widespread late-stage microbial methanogenesis occurred primarily along a CO{sub 2} reduction metabolic pathway. Organic compounds in the produced water appear to have helped sustain microbial communities. Ammonia and ammonium levels increase with total dissolved solids content and appear to have played a role in late-stage microbial methanogenesis and the generation of N{sub 2}. Gas production tends to decline exponentially, whereas water production tends to decline hyperbolically. Hyperbolic decline indicates that water volume is of greatest concern early in the life of a coalbed methane project. Regional mapping indicates that gas production is controlled primarily by the ability to depressurize permeable coal seams that are natively within the steep part of the adsorption isotherm. Water production is greatest within the freshwater intrusion and below thick Cretaceous cover strata and is least in areas of underpressure. Water management strategies include instream disposal, which can be applied effectively in most parts of the basin. Deep disposal may be applicable locally, particularly where high salinity limits the ability to dispose into streams. Artificial wetlands show promise for the management of saline water, especially where the reservoir yield is limited. Beneficial use options include municipal water supply, agricultural use, and industrial use. The water may be of use to an inland shrimp farming industry, which is active around the southwestern coalbed methane fields. The best opportunities for beneficial use are reuse of water by the coalbed methane industry for drilling and hydraulic fracturing. This research has further highlighted opportunities for additional research on treatment efficiency, the origin of nitrogen compounds, organic geochemistry, biogenic gas generation, flow modeling, and computer simulation. Results of this study are being disseminated through a vigorous technology transfer program that includes web resources, numerous presentations to stakeholders, and a variety of technical publications.

Correlation of producing Fruitland Formation coals within the western outcrop and coalbed methane leakage on the Southern Ute Reservation  

SciTech Connect

The Colorado Geological Survey and Southern Ute Indian Tribe proposed to determine the cause of several gas seeps which are occurring on the western outcrop of the coalbed methane producing Fruitland Formation on the Southern Ute Indian Reservation. Correlation between outcrop coals and subsurface coals was necessary to determine seep source in the northern part of the study area. Subsurface studies include structure and net coal isopach maps, stratigraphy was cross-sections, production maps, and a production database. Detailed coal stratigraphy was correlated through production wells near the outcrop region. These maps and cross-sections were correlated to new surface outcrop maps generated by the Colorado, Geological Survey and the Southern Ute Division of Energy Resources. Methane gas seepage has been noted historically within the study area. The total investigation may help determine if gas seepage is natural, a result of coalbed methane development, or some combination of the above.

Endangered species and cultural resources program, Naval Petroleum Reserves in California: Annual report FY95  

SciTech Connect

In FY95, EG and G Energy Measurements, Inc. (EG and G/EM) continued to support efforts to protect endangered species and cultural resources at the Naval Petroleum Reserves in California (NPRC). These efforts are conducted to ensure NPRC compliance with regulations regarding the protection of listed species and cultural resources on Federal properties. Population monitoring activities are conducted annually for San Joaquin kit foxes, giant kangaroo rats, blunt-nosed leopard lizards, and Hoover`s wooly-star. To mitigate impacts of oil field activities on listed species, 674 preactivity surveys covering approximately 211 hectares (521 acres) were conducted in FY95. EG and G/EM also assisted with mitigating effects from third-party projects, primarily by conducting biological and cultural resource consultations with regulatory agencies. EG and G/EM has conducted an applied habitat reclamation program at NPRC since 1985. In FY95, an evaluation of revegetation rates on reclaimed and non-reclaimed disturbed lands was completed, and the results will be used to direct future habitat reclamation efforts at NPRC. In FY95, reclamation success was monitored on 50 sites reclaimed in 1985. An investigation of factors influencing the distribution and abundance of kit foxes at NPRC was initiated in FY94. Factors being examined include habitat disturbance, topography, grazing, coyote abundance, lagomorph abundance, and shrub density. This investigation continued in FY95 and a manuscript on this topic will be completed in FY96. Also, Eg and G/EM completed collection of field data to evaluate the effects of a well blow-out on plant and animal populations. A final report will be prepared in FY96. Finally, EG and G/EM completed a life table analysis on San Joaquin kit foxes at NPRC.

Enhancement of Biogenic Coalbed Methane Production and Back Injection of Coalbed Methane Co-Produced Water  

SciTech Connect

Biogenic methane is a common constituent in deep subsurface environments such as coalbeds and oil shale beds. Coalbed methane (CBM) makes significant contributions to world natural gas industry and CBM production continues to increase. With increasing CBM production, the production of CBM co-produced water increases, which is an environmental concern. This study investigated the feasibility in re-using CBM co-produced water and other high sodic/saline water to enhance biogenic methane production from coal and other unconventional sources, such as oil shale. Microcosms were established with the selected carbon sources which included coal, oil shale, lignite, peat, and diesel-contaminated soil. Each microcosm contained either CBM coproduced water or groundwater with various enhancement and inhibitor combinations. Results indicated that the addition of nutrients and nutrients with additional carbon can enhance biogenic methane production from coal and oil shale. Methane production from oil shale was much greater than that from coal, which is possibly due to the greater amount of available Dissolved Organic Carbon (DOC) from oil shale. Inconclusive results were observed from the other sources since the incubation period was too low. WRI is continuing studies with biogenic methane production from oil shale.

Modeling Coal Matrix Shrinkage and Differential Swelling with CO2 Injection for Enhanced Coalbed Methane Recovery and Carbon Sequestration Applications  

SciTech Connect

Matrix shrinkage and swelling can cause profound changes in porosity and permeability of coalbed methane reservoirs during depletion or when under CO{sub 2} injection processes, with significant implication for primary or enhanced methane recovery. Two models that are used to describe these effects are discussed. The first was developed by Advanced Resources International (ARI) and published in 1990 by Sawyer, et al. The second model was published by Palmer and Mansoori in 1996. This paper shows that the two provide equivalent results for most applications. However, their differences in formulation cause each to have relative advantages and disadvantages under certain circumstances. Specifically, the former appears superior for undersaturated coalbed methane reservoirs while the latter would be better if a case is found where matrix swelling is strongly disproportional to gas concentration. Since its presentation in 1996, the Palmer and Mansoori model has justifiably received much critical praise. However, the model developed by ARI for the COMET reservoir simulation program has been in use since 1990, and has significant advantages in certain settings. A review of data published by Levine in 1996 reveals that carbon dioxide causes a greater degree of coal matrix swelling compared to methane, even when measured on a unit of concentration basis. This effect is described in this report as differential swelling. Differential swelling may have important consequences for enhanced coalbed methane and carbon sequestration projects. To handle the effects of differential swelling, an extension to the matrix shrinkage and swelling model used by the COMET simulator is presented and shown to replicate the data of Levine. Preliminary field results from a carbon dioxide injection project are also presented in support of the extended model. The field evidence supports that considerable changes to coal permeability occur with CO{sub 2} injection, with significant implication for the design, implementation and performance of enhanced coalbed methane recovery and CO{sub 2} sequestration projects.

Dewatering of coalbed methane wells with hydraulic gas pump  

SciTech Connect

The coalbed methane industry has become an important source of natural gas production. Proper dewatering of coalbed methane (CBM) wells is the key to efficient gas production from these reservoirs. This paper presents the Hydraulic Gas Pump as a new alternative dewatering system for CBM wells. The Hydraulic Gas Pump (HGP) concept offers several operational advantages for CBM wells. Gas interference does not affect its operation. It resists solids damage by eliminating the lift mechanism and reducing the number of moving parts. The HGP has a flexible production rate and is suitable for all production phases of CBM wells. It can also be designed as a wireline retrievable system. We conclude that the Hydraulic Gas Pump is a suitable dewatering system for coalbed methane wells.

Multicomponent 3-D characterization of a coalbed methane reservoir  

SciTech Connect

Methane is produced from fractured coalbed reservoirs at Cedar Hill Field in the San Juan Basin. Fracturing and local stress are critical to production because of the absence of matrix permeability in the coals. Knowledge of the direction of open fractures, the degree of fracturing, reservoir pressure, and compartmentalization is required to understand the flow of fluids through the reservoir. A multicomponent 3-D seismic survey was acquired to aid in coalbed methane reservoir characterization. Coalbed reservoir heterogeneities, including isolated pressure cells, zones of increased fracture density, and variable fracture directions, have been interpreted through the analysis of the multicomponent data and integration with petrophysical and reservoir engineering studies. Strike-slip faults, which compartmentalize the reservoir, have been identified by structural interpretation of the 3-D P-wave seismic data. These faults form boundaries for pressure cells that have been identified by P-wave reflection amplitude anomalies.

Exploiting coalbed methane and protecting the global environment  

SciTech Connect

The global climate change caused by greenhouse gases (GHGs) emission has received wide attention from all countries in the world. Global environmental protection as a common problem has confronted the human being. As a main component of coalbed methane, methane is an important factor influencing the production safety of coal mine and threatens the lives of miners. The recent research on environment science shows that methane is a very harmful GHG. Although methane gas has very little proportion in the GHGs emission and its stayed period is also very short, it has very obvious impact on the climate change. From the estimation, methane emission in the coal-mining process is only 10% of the total emission from human`s activities. As a clean energy, Methane has mature recovery technique before, during and after the process of mining. Thus, coalbed methane is the sole GHG generated in the human`s activities and being possible to be reclaimed and utilized. Compared with the global greenhouse effect of other GHGs emission abatement, coalbed methane emission abatement can be done in very low cost with many other benefits: (1) to protect global environment; (2) to improve obviously the safety of coal mine; and (3) to obtain a new kind of clean energy. Coal is the main energy in China, and coalbed contains very rich methane. According to the exploration result in recent years, about 30000{approximately}35000 billion m{sup 2} methane is contained in the coalbed below 2000 m in depth. China has formed a good development base in the field of reclamation and utilization of coalbed methane. The author hopes that wider international technical exchange and cooperation in the field will be carried out.

Integrated process for coalbed brine disposal  

SciTech Connect

A brine disposal process is described that converts the brine stream of a coalbed gas producing site into clean water for agricultural use, combustion products and water vapor that can be released into the atmosphere and dry solids that can be recycled for industrial consumption. The process uses a reverse osmosis unit, a submerged combustion evaporator and a pulse combustion dryer. Pretreatment of the brine feedstream is necessary to prevent fouling of the membranes of the reverse osmosis unit and to separate from the brine stream hazardous metal and other constituents that may make the permeate from the reverse osmosis unit unsuitable for agricultural or other use. A chemical modeling code is used to calculate the saturation states of solids that may precipitate and foul the reverse osmosis membranes. Sodium carbonate is added to the brine to precipitate carbonates of Ba, Ca, Mg and Sr prior to filtration, acidification, and passage into the reverse osmosis unit. Optimization of the process in terms of types and amounts of additives is possible with analysis using the modeling code. The minimum amounts of additives to prevent scaling are calculated. In a typical operation, a brine feedstream of 1,000 m{sup 3}/day (6,290 bpd) that may have a total dissolved salt concentration (TDS) of 7,000 ppm will be separated into a permeate stream of 750 m{sup 3}/day (4,718 bpd) with a TDS of 400 ppm and a concentrated brine stream of 250 m{sup 3}/day (1,573 bpd) with a TDS of 26,800 ppm. The submerged combustion evaporator will concentrate this latter stream to a concentration of 268,000 ppm and reduce the volume to 25 m{sup 3}/day (158 bpd). The pulse combustion dryer can dry the concentrated brine mixture to a low moisture salt. Energy costs to operate the reverse osmosis unit are primarily the pumping costs.

Exploration strategies based on a coalbed methane producibility model  

SciTech Connect

Knowing geologic and hydrologic characteristics of a basin does not necessarily lead to a determination of its coalbed methane producibility because it is the synergy among key hydrogeologic controls that governs producibility. Detailed studies performed in the San Juan, Piceance, and Sand Wash Basins determined that the key hydrogeologic factors affecting producibility include depositional setting and coal distribution, tectonic and structural setting, coal rank and gas generation, hydrodynamics, permeability, and gas content. The conceptual model based on these factors provides a rationale for exploration and development strategies for unexplored areas or in basins having established or limited production. Exceptionally high productivity requires good permeability; thick, laterally continuous high-rank and high-gas-content coals; dynamic flow of ground water through those coals; generation of secondary biogenic gases; and migration and conventional trapping of thermogenic and biogenic gases. Higher coalbed methane producibility commonly occurs in areas of upward flow associated with permeability barriers (no-flow boundaries). Fluid migration across a large gathering area orthogonal to permeability barriers and/or in situ generation of secondary biogenic gases concentrate the coal gas, resulting in higher gas contents. Low coalbed methane production is typically associated with very low permeability systems; the absence of conventional or hydrodynamic traps; and thin, low-rank coals below the threshold of thermogenic gas generation. Production from relatively low-gas-content coals in highly permeable recharge areas may result in excessive water and limited coalbed methane production. Thus, high permeability can be as detrimental to coalbed methane producibility as is low permeability.

Central-northern Appalachian coalbed methane flow grows  

SciTech Connect

Over the past decade in the US, coalbed methane (CBM) has become an increasingly important source of unconventional natural gas. The most significant CBM production occurs in the San Juan basin of Colorado and new Mexico and the Black Warrior basin of Alabama, which collective in 1995 accounted for about 94% of US CBM production. The paper discusses early CBM production, recent production, gas composition, undiscovered potential, and new exploration areas.

Coalbed methane exploration in the Lorraine Basin, France  

SciTech Connect

DuPont Conoco Hydrocarbures has been involved in a Coalbed Methane (CBM) project in France since 1991. Coalbed methane exploration differs noticeably in several aspects from conventional oil and gas exploration. This paper is divided in three parts and discusses some geological, reservoir and drilling considerations relevant to the exploration and appraisal of a coalbed methane prospect. The first part presents geological issues such as data collection and evaluation of its associated value, building expertise to create a geological and geophysical model integrating the work of a multidisciplinary team, and assessing uncertainties of the data interpretation. A short review of the basin activity, geological and tectonic setting, and environment aspects is presented in order to illustrate some CBM exploration issues. The second part describes a comprehensive coalbed methane reservoir data acquisition program incorporating coal sample optical and chemical analyses, gas sample chromatography, canister desorption, fracture density of coal cores, and measurement of in-situ coal permeability and bounding-strata stress. Field practical concerns are then discussed such as on-site and off-site canister desorption, gas sample collection, rapid estimation of gas content, ash content, total bed moisture, and finally well testing alternatives for permeability and rock stress determination. The third part reviews drilling issues such as drilling and coring options for core hole size and casing size, rig site equipment requirements for continuous coring operations, including mud treatment equipment, core handling material and core work stations, alliance of national and foreign drilling contractors to optimize equipment and experience, and finally overview of coring procedures to identify best practices for pending operations. The paper is derived from Conoco`s experience in CBM exploration in the Lorraine Basin, North East of France.

Coalbed methane production enhancement by underground coal gasification  

SciTech Connect

The sub-surface of the Netherlands is generally underlain by coal-bearing Carboniferous strata at greater depths (at many places over 1,500 m). These coal seams are generally thinner than 3 meter, occur in groups (5--15) within several hundred meters and are often fairly continuous over many square kilometers. In many cases they have endured complex burial history, influencing their methane saturation. In certain particular geological settings, a high, maximum coalbed methane saturation, may be expected. Carboniferous/Permian coals in the Tianjin-region (China) show many similarities concerning geological settings, rank and composition. Economical coalbed methane production at greater depths is often obstructed by the (very) low permeabilities of the coal seams as with increasing depth the deformation of the coal reduces both its macro-porosity (the cleat system) and microporosity. Experiments in abandoned underground mines, as well as after underground coal gasification tests indicate ways to improve the prospects for coalbed methane production in originally tight coal reservoirs. High permeability areas can be created by the application of underground coal gasification of one of the coal seams of a multi-seam cycle with some 200 meter of coal bearing strata. The gasification of one of the coal seams transforms that seam over a certain area into a highly permeable bed, consisting of coal residues, ash and (thermally altered) roof rubble. Additionally, roof collapse and subsidence will destabilize the overburden. In conjunction this will permit a better coalbed methane production from the remaining surrounding parts of the coal seams. Moreover, the effects of subsidence will influence the stress patterns around the gasified seam and this improves the permeability over certain distances in the coal seams above and below. In this paper the effects of the combined underground coal gasification and coalbed methane production technique are regarded for a single injection well. Known geotechnical aspects are combined with results from laboratory experiments on compaction of thermally treated rubble. An axi-symmetric numerical model is used to determine the effects induced by the gasified coal seam. The calculation includes the rubble formation, rubble compaction and induced stress effects in the overlying strata. Subsequently the stress effects are related to changes in coal permeability, based on experimental results of McKee et al.

State-of-the-art in coalbed methane drilling fluids  

SciTech Connect

The production of methane from wet coalbeds is often associated with the production of significant amounts of water. While producing water is necessary to desorb the methane from the coal, the damage from the drilling fluids used is difficult to assess, because the gas production follows weeks to months after the well is drilled. Commonly asked questions include the following: What are the important parameters for drilling an organic reservoir rock that is both the source and the trap for the methane? Has the drilling fluid affected the gas production? Are the cleats plugged? Does the 'filtercake' have an impact on the flow of water and gas? Are stimulation techniques compatible with the drilling fluids used? This paper describes the development of a unique drilling fluid to drill coalbed methane wells with a special emphasis on horizontal applications. The fluid design incorporates products to match the delicate surface chemistry on the coal, a matting system to provide both borehole stability and minimize fluid losses to the cleats, and a breaker method of removing the matting system once drilling is completed. This paper also discusses how coal geology impacts drilling planning, drilling practices, the choice of drilling fluid, and completion/stimulation techniques for Upper Cretaceous Mannville-type coals drilled within the Western Canadian Sedimentary Basin. A focus on horizontal coalbed methane (CBM) wells is presented. Field results from three horizontal wells are discussed, two of which were drilled with the new drilling fluid system. The wells demonstrated exceptional stability in coal for lengths to 1000 m, controlled drilling rates and ease of running slotted liners. Methods for, and results of, placing the breaker in the horizontal wells are covered in depth.

Development of coalbed methane in Mississippi Warrior Basin  

SciTech Connect

Since 1980, over 3,863 coalbed methane wells have been drilled in the Warrior basin of Alabama at a drilling cost of $1.138 billion. Production of 119 bcf of gas has been sold. The important findings of this study were probable coalbeds across Monroe County at depths and thicknesses being produced profitably in Alabama as well as in the Northern Appalachian and Central Appalachian basins. The logs showed the coal to often be close to conventional gas reservoirs in sandstone, indicating a probable equilibrium gas content of the adjacent coals. The most prevalent depth of the coal seams was 1,600-1,800 ft across northeast Monroe County from near the Alabama state line in the Splunge Field to the Four Mile Creek Field near the Tombigbee River. Individual seam thickness ranged up to 11 ft. Cumulative thickness of all coal in a single well was a maximum of 30 ft in the 1,000 ft to 2,000 ft interval usually logged. These estimates were based on density, compensated neutron, caliper, and gamma ray logs. A core hole would be necessary to verify exact thicknesses, presence of a seam, gas content, and permeability of the coal seams. It is stressed that conventional well logs have limitations, but they are a valid first estimate of the potential of an area. The subject study also verified the discovery of coal in Clay County reported by the Mississippi Bureau of Geology in 1989. Also, deep-lying coals were observed on logs of single wells in Noxubee, Oktibbeha, and Lowndes Counties, where one deep well had a cumulative 72 ft of coal indicated. Although beyond the reach of industry now, technology of the coalbed methane process is progressing toward eventually managing coal at those depths.

Assessment of CO2 Sequestration and ECBM Potential of U.S. Coalbeds  

SciTech Connect

In October, 2000, the U.S. Department of Energy, through contractor Advanced Resources International, launched a multi-year government-industry R&D collaboration called the Coal-Seq project. The Coal-Seq project is investigating the feasibility of CO{sub 2} sequestration in deep, unmineable coalseams, by performing detailed reservoir studies of two enhanced coalbed methane recovery (ECBM) field projects in the San Juan basin. The two sites are the Allison Unit, operated by Burlington Resources, and into which CO{sub 2} is being injected, and the Tiffany Unit, operating by BP America, into which N{sub 2} is being injected (the interest in understanding the N{sub 2}-ECBM process has important implications for CO{sub 2} sequestration via flue-gas injection). The purposes of the field studies are to understand the reservoir mechanisms of CO{sub 2} and N{sub 2} injection into coalseams, demonstrate the practical effectiveness of the ECBM and sequestration processes, an engineering capability to simulate them, and to evaluate sequestration economics. In support of these efforts, laboratory and theoretical studies are also being performed to understand and model multi-component isotherm behavior, and coal permeability changes due to swelling with CO{sub 2} injection. This report describes the results of an important component of the overall project, applying the findings from the San Juan Basin to a national scale to develop a preliminary assessment of the CO{sub 2} sequestration and ECBM recovery potential of U.S. coalbeds. Importantly, this assessment improves upon previous investigations by (1) including a more comprehensive list of U.S. coal basins, (2) adopting technical rationale for setting upper-bound limits on the results, and (3) incorporating new information on CO{sub 2}/CH{sub 4} replacement ratios as a function of coal rank. Based on the results of the assessment, the following conclusions have been drawn: (1) The CO{sub 2} sequestration capacity of U.S. coalbeds is estimated to be about 90 Gt. Of this, about 38 Gt is in Alaska (even after accounting for high costs associated with this province), 14 Gt is in the Powder River basin, 10 Gt is in the San Juan basin, and 8 Gt is in the Greater Green River basin. By comparison, total CO{sub 2} emissions from power generation plants is currently about 2.2 Gt/year. (2) The ECBM recovery potential associated with this sequestration is estimated to be over 150 Tcf. Of this, 47 Tcf is in Alaska (even after accounting for high costs associated with this province), 20 Tcf is in the Powder River basin, 19 Tcf is in the Greater Green River basin, and 16 Tcf is in the San Juan basin. By comparison, total CBM recoverable resources are currently estimated to be about 170 Tcf. (3) Between 25 and 30 Gt of CO{sub 2} can be sequestered at a profit, and 80-85 Gt can be sequestered at costs of less than $5/ton. These estimates do not include any costs associated with CO{sub 2} capture and transportation, and only represent geologic sequestration. (4) Several Rocky Mountain basins, including the San Juan, Raton, Powder River and Uinta appear to hold the most favorable conditions for sequestration economics. The Gulf Coast and the Central Appalachian basin also appear to hold promise as economic sequestration targets, depending upon gas prices. (5) In general, the 'non-commercial' areas (those areas outside the main play area that are not expected to produce primary CBM commercially) appear more favorable for sequestration economics than the 'commercial' areas. This is because there is more in-place methane to recover in these settings (the 'commercial' areas having already been largely depleted of methane).

L-FVM for Unsteady Seepage Flow in Low Permeability Coalbed  

SciTech Connect

The significant feature of coalbed in China is the low permeability. A new unsteady seepage flow model isdeveloped for the low permeability coalbed by considering the startup pressure gradient and methane desorption effect.Since the complexity of the problem, a new method which we call it ''L-FVM'' is developed, based on comparing the normal numerical calculation methods and comprehension research on FVM. The results show that L-FVM has the same precission but higher calculating velocity than normal FVM. This result is very important for monitoring the area pressure drawdown in coalbed methane engineering

The Savannah River Archaeological Research Program (SRARP) continued through FY95 with the United States Department of Energy to fulfill a threefold mission of cultural resource management, research, and public education at the Savannah River Site. Over 2,300 acres of land on the SRS came under cultural resources review in FY95. This activity entailed 30 field surveys, resulting in the recording of 86 new sites. Twenty-two existing sites within survey tract boundaries were revisited to update site file records. Research conducted by SRARP was reported in 11 papers and monographs published during FY95. SRARP staff also presented research results in 18 papers at professional meetings. Field research included several testing programs, excavations, and remote sensing at area sites, as well as data collection abroad. Seven grants were acquired by SRARP staff to support off-site research. In the area of heritage education, the SRARP expanded its activities in FY95 with a full schedule of classroom education, public outreach, and on-site tours. Volunteer excavations at the Tinker Creek site were continued with the Augusta Archaeological Society and other avocational groups, and other off-site excavations provided a variety of opportunities for field experience. Some 80 presentations, displays and tours were provided for schools, historical societies, civic groups, and environmental and historical awareness day celebrations. Additionally, SRARP staff taught four anthropology courses at area colleges.

Coalbed methane potential assessed in Forest City basin  

SciTech Connect

This paper reports that the Forest City basin is a shallow cratonic depression located in northeastern Kansas, southeastern Nebraska, southern Iowa and northern Missouri. Historically, the Forest City basin in northeastern Kansas has been a shallow oil and gas province with minor coal production. The Iowa and Missouri portion has had minor oil production and moderate coal mining. In recent years there has been little coal mining in the Forest City in Iowa and Kansas and only minor production in Missouri. Before 1940, gas was produced from coal beds and shales in the Kansas portion of the Forest City basin. The Cherokee group (Altokan and Desmoinesian age) includes section containing the largest number of actively mined coals and has the greatest available data for coalbed methane evaluation.

Coalbed-methane pilots - timing, design, and analysis  

SciTech Connect

Four distinct sequential phases form a recommended process for coalbed-methane (CBM)-prospect assessment: initial screening reconnaissance, pilot testing, and final appraisal. Stepping through these four phases provides a program of progressively ramping work and cost, while creating a series of discrete decision points at which analysis of results and risks can be assessed. While discussing each of these phases in some degree, this paper focuses on the third, the critically important pilot-testing phase. This paper contains roughly 30 specific recommendations and the fundamental rationale behind each recommendation to help ensure that a CBM pilot will fulfill its primary objectives of (1) demonstrating whether the subject coal reservoir will desorb and produce consequential gas and (2) gathering the data critical to evaluate and risk the prospect at the next-often most critical-decision point.

The EM SSAB Annual Work Plan Process: Focusing Board Efforts and Resources - 13667  

SciTech Connect

One of the most daunting tasks for any new member of a local board of the Environmental Management Site Specific Advisory Board (EM SSAB) is to try to understand the scope of the clean-up activities going on at the site. In most cases, there are at least two or three major cleanup activities in progress as well as monitoring of past projects. When planning for future projects is added to the mix, the list of projects can be long. With the clean-up activities involving all major environmental media - air, water, soils, and groundwater, new EM SSAB members can find themselves totally overwhelmed and ineffective. Helping new members get over this initial hurdle is a major objective of EM and all local boards of the EM SSAB. Even as members start to understand the size and scope of the projects at a site, they can still be frustrated at the length of time it takes to see results and get projects completed. Many project and clean-up timelines for most of the sites go beyond 10 years, so it's not unusual for an EM SSAB member to see the completion of only 1 or 2 projects over the course of their 6-year term on the board. This paper explores the annual work planning process of the EM SSAB local boards, one tool that can be used to educate EM SSAB members into seeing the broader picture for the site. EM SSAB local work plans divide the site into projects focused on a specific environmental issue or media such as groundwater and/or waste disposal options. Projects are further broken down into smaller segments by highlighting major milestones. Using these metrics, local boards of the EM SSAB can start to quantify the effectiveness of the project in achieving the ultimate goal of site clean-up. These metrics can also trigger board advice and recommendations for EM. At the beginning of each fiscal year, the EM SSAB work plan provides a road map with quantifiable checkpoints for activities throughout the year. When the work plans are integrated with site-specific, enforceable regulatory milestones, they can provide a comprehensive work plan for not only the board, but also regulators, site contractors, and DOE. Because the work plans are reviewed and approved by DOE, they carry some weight in holding local boards of the EM SSAB accountable. This structure provides the basis for local boards to achieve their primary function, to provide DOE with information, advice, and recommendations concerning issues affecting the EM program at the site.

Powder River Basin Coalbed Methane Development and Produced Water Management Study  

SciTech Connect

Coalbed methane resources throughout the entire Powder River Basin were reviewed in this analysis. The study was conducted at the township level, and as with all assessments conducted at such a broad level, readers must recognize and understand the limitations and appropriate use of the results. Raw and derived data provided in this report will not generally apply to any specific location. The coal geology in the basin is complex, which makes correlation with individual seams difficult at times. Although more than 12,000 wells have been drilled to date, large areas of the Powder River Basin remain relatively undeveloped. The lack of data obviously introduces uncertainty and increases variability. Proxies and analogs were used in the analysis out of necessity, though these were always based on sound reasoning. Future development in the basin will make new data and interpretations available, which will lead to a more complete description of the coals and their fluid flow properties, and refined estimates of natural gas and water production rates and cumulative recoveries. Throughout the course of the study, critical data assumptions and relationships regarding gas content, methane adsorption isotherms, and reservoir pressure were the topics of much discussion with reviewers. A summary of these discussion topics is provided as an appendix. Water influx was not modeled although it is acknowledged that this phenomenon may occur in some settings. As with any resource assessment, technical and economic results are the product of the assumptions and methodology used. In this study, key assumptions as well as cost and price data, and economic parameters are presented to fully inform readers. Note that many quantities shown in various tables have been subject to rounding; therefore, aggregation of basic and intermediate quantities may differ from the values shown.

Temperature–pressure conditions in coalbed methane reservoirs of the Black Warrior basin: implications for carbon sequestration and enhanced coalbed methane recovery  

Science Journals Connector (OSTI)

Sorption of gas onto coal is sensitive to pressure and temperature, and carbon dioxide can be a potentially volatile supercritical fluid in coalbed methane reservoirs. More than 5000 wells have been drilled in the coalbed methane fields of the Black Warrior basin in west-central Alabama, and the hydrologic and geothermic information from geophysical well logs provides a robust database that can be used to assess the potential for carbon sequestration in coal-bearing strata. Reservoir temperature within the coalbed methane target zone generally ranges from 80 to 125 °F (27–52 °C), and geothermal gradient ranges from 6.0 to 19.9 °F/1000 ft (10.9–36.2 °C/km). Geothermal gradient data have a strong central tendency about a mean of 9.0 °F/1000 ft (16.4 °C/km). Hydrostatic pressure gradients in the coalbed methane fields range from normal (0.43 psi/ft) to extremely underpressured (wells have pressure gradients greater than 0.30 psi/ft, and 20% have pressure gradients lower than 0.10 psi/ft. Pockets of underpressure are developed around deep longwall coal mines and in areas distal to the main hydrologic recharge zone, which is developed in structurally upturned strata along the southeastern margin of the basin. Geothermal gradients within the coalbed methane fields are high enough that reservoirs never cross the gas–liquid condensation line for carbon dioxide. However, reservoirs have potential for supercritical fluid conditions beyond a depth of 2480 ft (756 m) under normally pressured conditions. All target coal beds are subcritically pressured in the northeastern half of the coalbed methane exploration fairway, whereas those same beds were in the supercritical phase window prior to gas production in the southwestern half of the fairway. Although mature reservoirs are dewatered and thus are in the carbon dioxide gas window, supercritical conditions may develop as reservoirs equilibrate toward a normal hydrostatic pressure gradient after abandonment. Coal can hold large quantities of carbon dioxide under supercritical conditions, and supercritical isotherms indicate non-Langmiur conditions under which some carbon dioxide may remain mobile in coal or may react with formation fluids or minerals. Hence, carbon sequestration and enhanced coalbed methane recovery show great promise in subcritical reservoirs, and additional research is required to assess the behavior of carbon dioxide in coal under supercritical conditions where additional sequestration capacity may exist.

Thermogenic and secondary biogenic gases, San Juan Basin, Colorado and New Mexico - Implications for coalbed gas producibility  

SciTech Connect

The objectives of this paper are to (1) describe the types and the major components of coalbed gases, (2) evaluate the variability of Fruitland coalbed gas composition across the basin, (3) assess factors affecting coalbed gas origin and composition, (4) determine the timing and extent of gas migration and entrapment, and (5) suggest application of these results to coalbed gas producibility. Data from more than 750 Fruitland coalbed gas wells were used to make gas-composition maps and to evaluate factors controlling gas origin. The gas data were divided into overpressured, underpressured, and transitional categories based on regional pressure regime. Also, [delta][sup 13]C isotopic values from 41 methane, 7 ethane and propane, 13 carbon dioxide, and 10 formation-water bicarbonate samples were evaluated to interpret gas origin. The data suggests that only 25-50% of the gas produced in the high-productivity fairway was generated in situ during coalification. 82 refs., 14 figs., 3 tabs.

Unconventional Energy Resources: 2011 Review  

SciTech Connect

This report contains nine unconventional energy resource commodity summaries prepared by committees of the Energy Minerals Division (EMD) of the American Association of Petroleum Geologists. Unconventional energy resources, as used in this report, are those energy resources that do not occur in discrete oil or gas reservoirs held in structural or stratigraphic traps in sedimentary basins. These resources include coal, coalbed methane, gas hydrates, tight gas sands, gas shale and shale oil, geothermal resources, oil sands, oil shale, and uranium resources. Current U.S. and global research and development activities are summarized for each unconventional energy commodity in the topical sections of this report. Coal and uranium are expected to supply a significant portion of the world's energy mix in coming years. Coalbed methane continues to supply about 9% of the U.S. gas production and exploration is expanding in other countries. Recently, natural gas produced from shale and low-permeability (tight) sandstone has made a significant contribution to the energy supply of the United States and is an increasing target for exploration around the world. In addition, oil from shale and heavy oil from sandstone are a new exploration focus in many areas (including the Green River area of Wyoming and northern Alberta). In recent years, research in the areas of geothermal energy sources and gas hydrates has continued to advance. Reviews of the current research and the stages of development of these unconventional energy resources are described in the various sections of this report.

The analysis of the factors effect on coalbed methane pool concentration and high-production -- The North China coalbed methane districts as an example  

SciTech Connect

The factors which affect coalbed methane (CBM) pool concentration and high-production based upon the exploration and research of the North China CBM districts are coal facies, coal rank and metamorphic types, structural features, the surrounding rocks and their thickness, and hydrogeological conditions. Coal facies, coal rank and their metamorphic types mainly affect the CBM forming characteristic, while the other factors effect the trap of CBM pool. The interaction of the above factors determines the petrophysics of coal reservoirs and extractability of CBM. The high-production areas where CBM pools develop well in North China CBM districts are sites which have a favorable coordination of the five factors. The poor-production areas where CBM pools are undeveloped in North China are caused by action of one or more unfavorable factors. Therefore the favorable factors coordination is the prerequisite in selecting sites for coalbed methane recovery.

A model for changes in coalbed permeability during primary and enhanced methane, recovery  

SciTech Connect

The natural fracture network of a dual-porosity coalbed reservoir is made up of two sets of orthogonal, and usually subvertically oriented, cleats. Coalbed permeability has been shown to vary exponentially with changes in the effective horizontal stress acting across the cleats through the cleat-volume compressibility, which is analogous to pore compressibility in porous rocks. A formulation for changes in the effective horizontal stress of coalbeds during primary methane recovery, which includes a Langmuir type curve shrinkage term, has been proposed previously. This paper presents a new version of the stress formulation by making a direct link between the volumetric matrix strain and the amount of gas desorbed. The resulting permeability model can be extended readily to account for adsorption-induced matrix swelling as well as matrix shrinkage during enhanced methane recovery involving the injection of an inert gas or gas mixture into the seams. The permeability model is validated against a recently published pressure-dependent permeability multiplier curve representative of the San Juan basin coalbeds at post-dewatering production stages. The extended permeability model is then applied successfully to history matching a micropilot test involving the injection of flue gas (consisting mainly of CO{sub 2} and N{sub 2}) at the Fenn Big Valley, Alberta, Canada.

Gas-lift technology applied to dewatering of coalbed methane wells in the black warrior basin  

SciTech Connect

Coalbed methane (CBM) wells are usually dewatered with sucker rod or progressive cavity pumps to reduce wellbore water levels, although not without problems. This paper describes high-volume artificial-lift technology that incorporates specifically designed gas-lift methods to dewater Black Warrior CBM wells. Gas lift provides improved well maintenance and production optimization by the use of conventional wireline service methods.

Area balance and strain in coalbed methane reservoirs of the Black Warrior basin  

SciTech Connect

Investigation of coalbed methane reservoirs in the Black Warrior basin of Alabama has established a correspondence between productivity and structural position, but the reasons for this correspondence remain uncertain. In Cedar Cove field, for example, exceptionally productive wells are concentrated in a rollover anticline, whereas in Oak Grove field, exceptionally productive wells are aligned along a synclinal axis. This suggests that factors controlling gas production are a derivative of the structural geometry, and not the geometry by itself. Natural fractures and a low state of in-situ stress facilitate depressurization of coalbed reservoirs by dewatering, and hence, desorption and production of coalbed gas. Our hypothesis is that the abundance and openness of natural fractures in the Black Warrior basin are a direct expression of the layer-parallel strain dictated by map-scale structural geometry. Area balancing techniques can be used to quantify requisite strain, which is the homogeneous layer-parallel strain required for local area balance, and can also be used to constrain and verify structural cross sections. Application of area balancing techniques to extensional structures in the Black Warrior basin indicates that coalbed gas is produced from thin-skinned structures detached within the coal-bearing Pottsville Formation. Within reservoir intervals, requisite strain values are as high as 10 percent and increase downward toward the basal detachment. Mapping structure and production indicates that some productivity sweet spots correlate with enhanced bed curvature. Whereas requisite strain is the homogeneous strain calculated for discrete bed segments, curvature affects the distribution of strain within those segments. Recognizing this, our research is now focused on integrating area balancing techniques with curvature analysis to explain production patterns in coalbed methane reservoirs.

Coordinated studies in support of hydraulic fracturing of coalbed methane. Annual report, June 1990-October 1991  

SciTech Connect

The production of natural gas coal typically requires stimulation in the form of hydraulic fracturing. The results of hydraulic fracturing treatments have ranged from highly successful to less than satisfactory. The approach in the work has been to experimentally evaluate parameters that pertain to coal fluid interactions during hydraulic fracturing and post-frac production and then apply the findings to the selection of fracturing fluids and treatment design. Evaluated parameters include leakoff through cleats, pressure drops through cleated slots with slurries, proppant transport, conductivity, and coal matrix damage due to fracturing fluids. Some conclusions from the work include (1) 100 mesh sand alone can control leakoff through cleats; (2) coal faces alone do not increase pressure drop through fractures with slurries; (3) restrictions approaching 2 proppant diameters are required to see pressure increases; (4) borate fluid pH's of 9.5 are required for transport; (5) mixed proppant conductivities of 100 mesh and 16/30 can be 50% lower than the larger proppant; (6) guar based fracturing fluids can cause up to 90% permeability damage to the coal matrix; (7) HEC containing foams provide the best cleanup in the laboratory (only 10 to 30% damage and have shown excellent results in field trials); and (8) expanded use of COMPAS is recommended to document field results.

Coordinated studies in support of hydraulic fracturing of coalbed methane. Annual report, November 1991-December 1992  

SciTech Connect

The purpose of the work is to characterize common and potential fracturing fluids in terms of coal-fluid interactions to identify reasons for less than satisfactory performance and to ultimately devise alternative fluids and treatment procedures to optimize production following hydraulic fracturing. The laboratory data reported herein has proven helpful in designing improved hydraulic fracturing treatments and remedial treatments in the Black Warrior Basin. Acid inhibitors, scale inhibitors, additives to improve coal relative permeability to gas, and non-damaging polymer systems for hydraulic fracturing have been screened in coal damage tests. The optimum conditions for creating field-like foams in the laboratory have been explored. Tests have been run to identify minimum polymer and surfactant concentrations for applications of foam in coal. The roll of 100 mesh sand in controlling leakoff and impairing conductivity in coal has been investigated.

In March 2003, the U.S. Geological Survey, the Louisiana Geological Survey, and EnerVest Management Partners Ltd. participated in a Cooperative Research and Development Agreement (CRADA) to drill and core the Fairbanks Real Estate No. 359 (FRE No. 359) coalbed methane test well in Ouachita Parish, Louisiana. This effort was in support of ongoing U.S. Geological Survey investigations into the coal gas potential of the Gulf Coastal Plain. To determine possible relationships between coalbed gas content and coal composition, maceral modes were determined for 17 subsurface coal and carbonaceous shale samples cored and desorbed from the Paleocene-Eocene Wilcox Group. Similar determinations of maceral mode were made on cuttings collected from 5 non-cored coaly intervals in the overlying Eocene Sparta Sand. 22 refs., 11 figs., 3 tabs.

Well testing in coalbed methane (CBM) wells: An environmental remediation case history  

SciTech Connect

In 1993, methane seepage was observed near coalbed methane wells in southwestern Colorado. Well tests were conducted to identify the source of the seeps. The well tests were complicated by two-phase flow, groundwater flow, and gas readsorption. Using the test results, production from the area was simulated. The cause of the seeps was found to be depressuring in shallow coal near the surface, and a remediation plan using water injection near the seep area was formulated.

Geological controls on prediction of coalbed methane of No. 3 coal seam in Southern Qinshui Basin, North China  

Science Journals Connector (OSTI)

In order to better understand the geological controls on coalbed methane (CBM) in Southern Qinshui basin (SQB), North China, geological surveys and laboratory experiments, including coal petrology analysis, proximate analysis and methane adsorption/desorption, were conducted. Results show that the coals from the SQB contain 0.59–3.54% moisture, 3.5–15.54% ash yield, 73.62–88.92% fixed carbon and 2.14–4.04% hydrogen, with C/H ratios in the range of 19.96–36.25. The vitrinite reflectance (Ro,m) ranges from 1.95 to 3.49%. The coals are composed of 18.5–97.4% vitrinite and 2.4–81.4% inertinite. The geologic structures, coal-bearing strata and coal depositional environment were studied by both field geological research and laboratory tests. A positive relationship is found between CBM content and basin hydrodynamics, in which CBM easily concentrates in the groundwater stagnant zone because of the water pressure. Furthermore, integrated geographical information system (GIS) and analytical hierarchy fuzzy prediction method (AHP) were used to evaluate the CBM resources in the SQB. The results show that the amount of CBM associated with the No. 3 coal seam in the SQB is 3.62 × 1011 m3. The CBM resource concentration (gas-in-place per square kilometer) in the SQB is in the range of (0.72–2.88) × 108 m3/km2, with an average of 1.21 × 108 m3/km2, which decreases from Zhengzhuang coal district to Shitou fault and from Fanzhuang coal district to the margins of the basin. The best prospective targets for CBM production are likely located in the southwest/northwest Zhengzhuang and central Hudi coal districts.

Geologic and hydrologic controls on coalbed methane producibility, Williams Fork Formation, Piceance Basin, Colorado  

SciTech Connect

Structural and depositional setting, coal rank, gas content, permeability, hydrodynamics, and reservoir heterogeneity control the producibility of coalbed methane in the Piceance Basin. The coal-rich Upper Cretaceous, Williams Fork Formation is genetically defined and regionally correlated to the genetic sequences in the Sand Wash Basin, to the north. Net coal is thickest in north-south oriented belts which accumulated on a coastal plain, behind west-east prograding shoreline sequences. Face cleats of Late Cretaceous age strike E-NE and W-NW in the southern and northern parts of the basin, respectively, normal to the Grand Hogback thrust front. Parallelism between face-cleat strike and present-day maximum horizontal stresses may enhance or inhibit coal permeability in the north and south, respectively. Geopressure and hydropressure are both present in the basin with regional hydrocarbon overpressure dominant in the central part of the basin and hydropressure limited to the basin margins. The most productive gas wells in the basin are associated with structural terraces, anticlines, and/or correspond to Cameo-Wheeler-Fairfield coal-sandstone development, reflecting basement detached thrust-faulting, fracture-enhanced permeability, and reservoir heterogeneity. Depositional heterogeneties and thrusts faults isolate coal reservoirs along the Grand Hogback from the subsurface by restricting meteoric recharge and basinward flow of ground water. An evolving coalbed methane producibility model predicts that in the Piceance Basin extraordinary coalbed methane production is precluded by low permeability and by the absence of dynamic ground-water flow.

Subsurface definition of the Allegheny Group coalbed methane prospect interval in Southwestern Pennsylvania and new gas content results  

SciTech Connect

A preliminary reconnaissance of coalbed methane gas content data from exploratory coal cores and pre-existing data implies that the greater the depth and rank, the greater the total and cumulative gas content. The coal seams studied, ranging in age from the Pennsylvanian-Permian Dunkard Group to the Middle Pennsylvanian Allegheny Group, are from the Main Bituminous Field and two of the anthracite fields. Consequently, the Pennsylvania Geological Survey and the West Virginia Geological and Economic Survey conducted a mapping investigation to evaluate the regional geology of the coal-bearing intervals and its influence on coalbed methane potential. Phase I of this study involved the entire Pennsylvanian coal-bearing interval; Phase II focused on a stratigraphic delineation and evaluation of Allegheny coalbeds and associated sandstones. A variety of cross sections and isopach maps show several prospective coalbeds and facies relationships with channel-fill sandstones. This suggests that some of these sandstones may be traps for coalbed methane. Often overlooked in reservoir characterization is the quality of a coal seam. Coal rank, grade, and type influence the reserves and production of coalbed methane; the higher the rank, the greater adsorptive capacity of the coal. The integration of coal quality with other critical tools of exploration may increase the success rate of finding {open_quotes}sweet spots.{close_quotes} Additional Pennsylvania Geological Survey drilling occurred in Beaver, Lawrence, Somerset, and Washington counties. Gas contents were graphically displayed against depth, thickness, and time for a variety of samples from 21 coal seams; average gas composition and Btu values were determined for selected samples.

Coalbed methane potential of the Pechora Coalfield, Timan-Pechora Basin, Russia  

SciTech Connect

A comparison of the more important geologic attributes of coal beds in the coalbed methane producing regions of the United States to Permian coal beds in the Pechora Coalfield, Timan-Pechora Basin, Russia indicates a high potential for commercial coalbed methane production. Although the depositional and structural histories, as well as the age, of the coal beds in the Pechora Coalfield are different than coal beds in U.S. basins, coal quality attributes are similar. The more prospective part of the coal-bearing sequence is as thick as 1600 m and contains more than 150 coal beds that individually are as thick as 4 m. These coal beds are composed primarily of rank ranges from subbituminous to anthracite (,0.5->2.5% R[sub 0]), with the highest rank coal located near the city of Vorkuta. Published data indicates that the gas content of coals is as high as 28-35 m[sup 3]/ton, with an average value of 18 m[sup 3]/ton. About 700 MMCM of gas per year is emmitted from coal mines. Pore pressures in the coal beds are unknown, however, interbedded sandstones in some parts of the basin are overpressured. The commonly occurring problem, in mid-latitude coalbed methane well, of excessive amounts of water may be alleviated in this high-latitude coal field. We suggest that the wide-spread occurrence of permafrost in the Pechora Coalfield may form an effective barrier to down-dip water flow, thereby facilitating the dewatering state. In summary, the quality of coal beds in the Pechora Coalfield are similar to methane producing coal beds in the United States and should, therefore, be favorable for commercial rates of gas production.

Coalbed methane stimulation techniques: Mechanisms and applicability. Topical report, August 1991-July 1993  

SciTech Connect

Increased pore pressure around a wellbore during injection into a coalbed reservoir can cause increased stresses, degradation in mechanical properties and plastic deformation. These near-wellbore effects can lead to elevated breakdown and treatment pressures during hydraulic fracturing and alternatively can promote cavity evolution and conductivity-connectivity alteration during dynamic openhole cavitation. Laboratory experimentation and field data interpretation are provided to support these contentions. Practical considerations for controlling excessive pressure during hydraulic fracturing are suggested as are similar considerations for maximizing cavity growth, deliverability, applicability, and formation evaluation.

Coal fluid interactions studies, fracture conductivity, fluid leak-off through cleats, rheology, and proppant transport are designed to respresent Black Warrior and San Juan treatments. A second objective is to apply the information learned in laboratory testing to actual hydraulic fracturing treatments in order to improve results. A final objective is to review methods currently used to catalog well performance following hydraulic fracturing for the purpose of placing the data in a useable database that can be accessed by users to determine the success of various treatment scenarios.

GEOLOGIC SCREENING CRITERIA FOR SEQUESTRATION OF CO2 IN COAL: QUANTIFYING POTENTIAL OF THE BLACK WARRIOR COALBED METHANE FAIRWAY, ALABAMA  

SciTech Connect

Sequestration of CO{sub 2} in coal has potential to reduce greenhouse gas emissions from coal-fired power plants while enhancing coalbed methane recovery. Data from more than 4,000 coalbed methane wells in the Black Warrior basin of Alabama provide an opportunity to quantify the carbon sequestration potential of coal and to develop a geologic screening model for the application of carbon sequestration technology. This report summarizes stratigraphy and sedimentation, structural geology, geothermics, hydrology, coal quality, gas capacity, and production characteristics of coal in the Black Warrior coalbed methane fairway and the implications of geology for carbon sequestration and enhanced coalbed methane recovery. Coal in the Black Warrior basin is distributed among several fluvial-deltaic coal zones in the Lower Pennsylvanian Pottsville Formation. Most coal zones contain one to three coal beds that are significant targets for coalbed methane production and carbon sequestration, and net coal thickness generally increases southeastward. Pottsville strata have effectively no matrix permeability to water, so virtually all flow is through natural fractures. Faults and folds influence the abundance and openness of fractures and, hence, the performance of coalbed methane wells. Water chemistry in the Pottsville Formation ranges from fresh to saline, and zones with TDS content lower than 10,000 mg/L can be classified as USDW. An aquifer exemption facilitating enhanced recovery in USDW can be obtained where TDS content is higher than 3,000 mg/L. Carbon dioxide becomes a supercritical fluid above a temperature of 88 F and a pressure of 1,074 psi. Reservoir temperature exceeds 88 F in much of the study area. Hydrostatic pressure gradients range from normal to extremely underpressured. A large area of underpressure is developed around closely spaced longwall coal mines, and areas of natural underpressure are distributed among the coalbed methane fields. The mobility and reactivity of supercritical CO{sub 2} in coal-bearing strata is unknown, and potential exists for supercritical conditions to develop below a depth of 2,480 feet following abandonment of the coalbed methane fields. High-pressure adsorption isotherms confirm that coal sorbs approximately twice as much CO{sub 2} as CH{sub 4} and approximately four times as much CO{sub 2} as N{sub 2}. Analysis of isotherm data reveals that the sorption performance of each gas can vary by a factor of two depending on rank and ash content. Gas content data exhibit extreme vertical and lateral variability that is the product of a complex burial history involving an early phase of thermogenic gas generation and an ongoing stage of late biogenic gas generation. Production characteristics of coalbed methane wells are helpful for identifying areas that are candidates for carbon sequestration and enhanced coalbed methane recovery. Many geologic and engineering factors, including well construction, well spacing, and regional structure influence well performance. Close fault spacing limits areas where five-spot patterns may be developed for enhanced gas recovery, but large structural panels lacking normal faults are in several gas fields and can be given priority as areas to demonstrate and commercialize carbon sequestration technology in coalbed methane reservoirs.

The Coal Ash Resources Research Consortium (CARRC, pronounced cars), formerly the Western Fly Ash Research, Development, and Data Center (WFARDDC), has continued fundamental and applied scientific and engineering research focused on promoting environmentally safe, economical use of coal combustion fly ash. The research tasks selected for the year included: (1) Coal Ash Properties Database Maintenance and Expansion, (2) Investigation of the High-Volume Use of Fly Ash for Flowable Backfill Applications, (3) Investigation of Hydrated Mineralogical Phases in Coal Combustion By-Products, (4) Comparison of Department of Transportation Specifications for Coal Ash Utilization, (5) Comparative Leaching Study of Coal Combustion By-Products and Competing Construction Materials, (6) Application of CCSEM for Coal Ash Characterization, (7) Determination of Types and Causes of Efflorescence in Regional Concrete Products, and (8) Sulfate Resistance of Fly Ash Concrete: A Literature Review and Evaluation of Research Priorities. The assembly of a database of information on coal fly ash has been a focus area for CARRC since its beginning in 1985. This year, CARRC members received an updated run time version of the Coal Ash Properties Database (CAPD) on computer disk for their use. The new, user-friendly database management format was developed over the year to facilitate the use of CAPD by members as well as CARRC researchers. It is anticipated that this direct access to CAPD by members as well as CARRC researchers. It is anticipated that this direct access to CAPD by members will be beneficial to each company`s utilization efforts, to CARRC, and to the coal ash industry in general. Many additions and improvements were made to CAPD during the year, and a three-year plan for computer database and modeling related to coal ash utilization was developed to guide both the database effort and the research effort.

A parametric study on the benefits of drilling horizontal and multilateral wells in coalbed methane reservoirs  

SciTech Connect

Recent years have witnessed a renewed interest in development of coalbed methane (CBM) reservoirs. Optimizing CBM production is of interest to many operators. Drilling horizontal and multilateral wells is gaining Popularity in many different coalbed reservoirs, with varying results. This study concentrates on variations of horizontal and multilateral-well configurations and their potential benefits. In this study, horizontal and several multilateral drilling patterns for CBM reservoirs are studied. The reservoir parameters that have been studied include gas content, permeability, and desorption characteristics. Net present value (NPV) has been used as the yard stick for comparing different drilling configurations. Configurations that have been investigated are single-, dual-, tri-, and quad-lateral wells along with fishbone (also known as pinnate) wells. In these configurations, the total length of horizontal wells and the spacing between laterals (SBL) have been studied. It was determined that in the cases that have been studied in this paper (all other circumstances being equal), quadlateral wells are the optimum well configuration.

Low temperature iron- and nickel-catalyzed reactions leading to coalbed gas formation  

SciTech Connect

Hydrocarbon hydrogenolysis and CO{sub 2} hydrogenation in the presence of Fe/SiO{sub 2} and Ni/SiO{sub 2} catalysts were evaluated as potential mechanisms contributing to natural gas formation in coalbeds. The hydrocarbons used as reactants in hydrogenolysis included butane, octane, 1-octene, and 1-dodecene. The reactions carried out in a laboratory batch reactor produced gas that contained methane concentrations greater than 90%, which resembles the composition of natural gas. Reaction temperatures were selected to resemble natural coalbed conditions. Evidence is presented to show that iron and nickel minerals, which can be present in coals at levels of 2,000 and 10 ppm, respectively, can become active under geologic conditions. The oxides (Fe{sub 2}O{sub 3} and NiO) used as precursors of the active catalysts (Fe and Ni metals) were reduced at 200 C under a hydrogen atmosphere. Moessbauer spectroscopy showed that ca. 6% of the iron oxide was converted to the metal; in the case of nickel, oxygen titration showed that the extent of reduction to the metal was ca. 29%. The resultant fractions of the active metals in coals are adequate to catalyze generation of appreciable amounts of methane over geologic time.

A review on recent advances in the numerical simulation for coalbed-methane-recovery process  

SciTech Connect

The recent advances in numerical simulation for primary coalbed methane (CBM) recovery and enhanced coalbed-methane recovery (ECBMR) processes are reviewed, primarily focusing on the progress that has occurred since the late 1980s. Two major issues regarding the numerical modeling will be discussed in this review: first, multicomponent gas transport in in-situ bulk coal and, second, changes of coal properties during methane (CH{sub 4}) production. For the former issues, a detailed review of more recent advances in modeling gas and water transport within a coal matrix is presented. Further, various factors influencing gas diffusion through the coal matrix will be highlighted as well, such as pore structure, concentration and pressure, and water effects. An ongoing bottleneck for evaluating total mass transport rate is developing a reasonable representation of multiscale pore space that considers coal type and rank. Moreover, few efforts have been concerned with modeling water-flow behavior in the coal matrix and its effects on CH{sub 4} production and on the exchange of carbon dioxide (CO{sub 2}) and CH{sub 4}. As for the second issue, theoretical coupled fluid-flow and geomechanical models have been proposed to describe the evolution of pore structure during CH{sub 4} production, instead of traditional empirical equations. However, there is currently no effective coupled model for engineering applications. Finally, perspectives on developing suitable simulation models for CBM production and for predicting CO{sub 2}-sequestration ECBMR are suggested.

Microbial degradation of sedimentary organic matter associated with shale gas and coalbed methane in eastern Illinois Basin (Indiana), USA  

Science Journals Connector (OSTI)

Molecular biodegradation indices for extracts from five Pennsylvanian coals and six New Albany Shale (Devonian – Mississippian) samples from the eastern part of the Illinois Basin help constrain relationships between the degradation of biomarkers and the generation of coalbed methane and shale gas. Investigation of these gas source rocks of varying thermal maturity from different depths facilitates evaluation of the association of microbial degradation with biogenic gas formation distinct from thermogenic processes. Extensive biodegradation of both aliphatic and aromatic hydrocarbons is observed in the coal extracts, whereas in shale extracts only short-chain (C15–C19) n-alkanes from the shallowest depth appear to be microbially altered with minimal evidence for losses of acyclic isoprenoid alkanes and aromatic hydrocarbons. By contrast, biodegradation of aromatic hydrocarbons, specifically alkylated naphthalenes and phenanthrenes, occurs in coal extracts in concert with losses of n-alkanes attributable to microbial activity. Thus, the progress of hydrocarbon biodegradation in coals differs from the sequence recognized in petroleum where the effects of microbial alteration of aromatic constituents only appear after extensive losses of aliphatic compounds. The extent of hydrocarbon biodegradation in these coals also decreases with depth, as recorded by the ?(nC25–nC30) index (i.e. abundance relative to 17?(H), 21?(H)-hopane) among the aliphatic constituents and several aromatic compounds (methyl-, dimethyl-, and trimethylnaphthalenes, phenanthrene, and trimethyl- and tetramethylphananthrenes). However, the depth variations in the distributions of aliphatic and aromatic hydrocarbons in the shale extracts primarily reflect the effects of thermal maturity rather than biodegradation. Overall, variations in the extent and patterns of biomarker biodegradation among coals and shales likely reflect their distinct microbial consortia that can be attributed to differences in (i) surviving microorganisms and inoculations from meteoric water, (ii) the characteristics of the sedimentary organic matter, especially the preponderance of aromatic constituents in coals, and (iii) the accessibility to that substrate through pores and cleats. These results help constrain the processes involved in biodegradation and controls on its extent, which, in turn, assist in recognizing sites favorable for methanogenesis and improved estimates of biogenic gas resources in the Illinois Basin.

Damage tolerance of well-completion and stimulation techniques in coalbed methane reservoirs  

SciTech Connect

Coalbed methane (CBM) reservoirs are characterized as naturally fractured, dual porosity, low permeability, and water saturated gas reservoirs. Initially, the gas, water and coal are at thermodynamic equilibrium under prevailing reservoir conditions. Dewatering is essential to promote gas production. This can be accomplished by suitable completion and stimulation techniques. This paper investigates the efficiency and performance of the openhole cavity, hydraulic fractures, frack and packs, and horizontal wells as potential completion methods which may reduce formation damage and increase the productivity in coalbed methane reservoirs. Considering the dual porosity nature of CBM reservoirs, numerical simulations have been carried out to determine the formation damage tolerance of each completion and, stimulation approach. A new comparison parameter named as the normalized productivity index is defined as the ratio of the productivity index of a stimulated well to that of a nondamaged vertical well as a function of time. Typical scenarios have been considered to evaluate the CBM properties, including reservoir heterogeneity, anisotropy, and formation damage, for their effects on this index over the production time. The results for each stimulation technique show that the value of the index declines over the time of production with a rate which depends upon the applied technique and the prevailing reservoir conditions. The results also show that horizontal wells have the best performance if drilled orthogonal to the butt cleats. Open-hole cavity completions outperform vertical fractures if the fracture conductivity is reduced by any damage process. When vertical permeability is much lower than horizontal permeability, production of vertical wells will improve while productivity of horizontal wells will decrease.

Coalbed gases and hydrocarbon source rock potential of upper Carboniferous coal-bearing strata in upper Silesian Coal Basin, Poland  

SciTech Connect

The Upper Silesian Coal Basin (USCB) is one of the major Upper Carboniferous coal basins in the world. Its coalbed gas reserves to the depths of 1,000 m are estimated to be about 350 billion cubic meters (about 12.4 TCF). Coalbed gases in the USCB are variable in both molecular and stable isotope composition [{delta}{sup 13}C(CH{sub 4}), {delta}D(CH{sub 4}), {delta}{sup 13}C(C{sub 2}H{sub 6}), {delta}{sup 13}C(C{sub 3}H{sub 8}), {delta}{sup 13}C(CO{sub 2})]. Such variability suggests the effects of both primary reactions operating during the generation of gases and secondary processes such as mixing and migration. Coalbed gases are mostly thermogenic methane in which depth-related isotopic fractionation has resulted from migration but not from mixing with the microbial one. The stable carbon isotope composition indicates that the carbon dioxide, ethane and higher gaseous hydrocarbons were generated during the bituminous coal stage of the coalification process. The main stage of coalbed gas generation occurred during the Variscan orogeny, and generation was completed after the Leonian and Asturian phases of this orogeny. The coals and carbonaceous shales have high gas generation potential but low potential for generation and expulsion of oil compared to the known Type III source rocks elsewhere. In general, the carbonaceous shales have slightly higher potential for oil generation, but probably would not be able to exceed expulsion thresholds necessary to expel economic quantities of oil.

CO2 Sequestration in Coalbed Methane Reservoirs: Experimental Studies and Computer Simulations  

SciTech Connect

One of the approaches suggested for sequestering CO{sub 2} is by injecting it in coalbed methane (CBM) reservoirs. Despite its potential importance for CO{sub 2} sequestration, to our knowledge, CO{sub 2} injection in CBM reservoirs for the purpose of sequestration has not been widely studied. Furthermore, a key element missing in most of the existing studies is the comprehensive characterization of the CBM reservoir structure. CBM reservoirs are complex porous media, since in addition to their primary pore structure, generated during coal formation, they also contain a variety of fractures, which may potentially play a key role in CO{sub 2} sequestration, as they generally provide high permeability flow paths for both CO{sub 2} and CH{sub 4}. In this report we present an overview of our ongoing experimental and modeling efforts, which aim to investigate the injection, adsorption and sequestration of CO{sub 2} in CBM reservoirs, the enhanced CH{sub 4} production that results, as well as the main factors that affect the overall operation. We describe the various experimental techniques that we utilize, and discuss their range of application and the value of the data generated. We conclude with a brief overview of our modeling efforts aiming to close the knowledge gap and fill the need in this area.

Engineering study of coalbed degasification in the Warrior Basin of Alabama  

SciTech Connect

This project was an engineering study of coalbed methane extraction in the Warrior Basin of Alabama. The coal lithology logs and the production histories of major degasification fields in the Warrier Basin were studied in detail. A comparative analysis of gas and water production of different wells was conducted to evaluate open hole completions and through-casing completions. A similar analysis was made to evaluate different stimulation techniques. Attempts were made to evaluate the relations between the uncemented portions. Logs from The University of Alabama's corehole program and the production well were analyzed. Laboratory experiments were conducted to establish the porosities and permeability of the cores obtained from zones adjacent to the producing zones of the University's production well. The results indicated that the water would be much lower, unless fractures have propagated into these zones. The results of water analysis show no indication of freshwater channeling. An experiment has been proposed to make a comparative evaluation of different stimulation techniques. A preliminary study has been completed to explore the possibility of using chemicals for increasing permeability in coal. Further research in this area might result in significantly improving methods for stimulation of these coal seams. 29 references, 19 figures, 5 tables.

A dynamic prediction model for gas–water effective permeability based on coalbed methane production data  

Science Journals Connector (OSTI)

Abstract An understanding of the relative permeability of gas and water in coal reservoirs is vital for coalbed methane (CBM) development. In this work, a prediction model for gas–water effective permeability is established to describe the permeability variation within coal reservoirs during production. The effective stress and matrix shrinkage effects are taken into account by introducing the Palmer and Mansoori (PM) absolute permeability model. The endpoint relative permeability is calibrated through experimentation instead of through the conventional Corey relative permeability model, which is traditionally employed for the simulation of petroleum reservoirs. In this framework, the absolute permeability model and the relative permeability model are comprehensively coupled under the same reservoir pressure and water saturation conditions through the material balance equation. Using the Qinshui Basin as an example, the differences between the actual curve that is measured with the steady-state method and the simulation curve are compared. The model indicates that the effective permeability is expressed as a function of reservoir pressure and that the curve shape is controlled by the production data. The results illustrate that the PM–Corey dynamic prediction model can accurately reflect the positive and negative effects of coal reservoirs. In particular, the model predicts the matrix shrinkage effect, which is important because it can improve the effective permeability of gas production and render the process more economically feasible.

Factors controlling high-yield coalbed methane vertical wells in the Fanzhuang Block, Southern Qinshui Basin  

Science Journals Connector (OSTI)

Abstract Whether a coalbed methane (CBM) well achieves high yield is controlled by various factors. Structural and hydrological control models of CBM productivity in vertical wells were built using a combined investigation of basic tectonic settings and hydrological conditions, as well as drainage parameters of the coal reservoir in the Fanzhuang Block, Southern Qinshui Basin. This study indicates that gas/water production differs significantly among wells with different structural settings or hydrogeological conditions. Low and unstable gas production rates in individual wells are the primary problem for the CBM development in the Fanzhuang Block. The impacts of some geologic and engineering factors on gas production were analyzed and estimated based on comparative analysis, quantitative analysis, and gray system theory. The results indicate that the critical reservoir ratio (CRR), liquid column height (LCH), and gas content are the most important factors in determining well productivity, followed by the equivalent drainage radius (EDR), the volume of frac sand, and the decline rate of working fluid levels during initial production. High-yield wells in the Fanzhuang Block always have the following conditions: gas content > 20 m3/t; burial depth of 500–700 m; CRR > 0.7; LCH > 400 m; volume of frac sand > 40 m3; EDR of 30–60 m; and a decline rate of working fluid level lower than 2 m/day during the initial production stage.

Coal-bed methane production in eastern Kansas: Its potential and restraints  

SciTech Connect

In 1921 and again in 1988, workers demonstrated that the high volatile A and B coals of the Pennsylvanian Cherokee Group can be produced economically from vertically drilled holes, and that some of these coals have a gas content as high as 200 ft{sup 3}/ton. Detailed subsurface mapping on a county-by-county basis using geophysical logs shows the Weir coal seam to be the thickest (up to 6 ft thick) and to exist in numerous amoeba-shaped pockets covering several thousand acres. Lateral pinch-out into deltaic sands offers a conventional gas source. New attention to geophysical logging shows most coals have a negative SP response, high resistivities, and densities of 1.6 g/cm{sup 3}. Highly permeable coals cause lost circulation during drilling and thief zones during cementing, and they are the source of abundant unwanted salt water. Low-permeability coals can be recognized by their high fracture gradients, which are difficult to explain but are documented to exceed 2.2. Current successful completions use both limited-entry, small-volume nitrogen stimulations or an open hole below production casing. Subsurface coals are at normal Mid-Continent pressures and may be free of water. Initially, some wells flow naturally without pumping. Saltwater disposal is often helped by the need for water in nearby waterflood projects and the easy availability of state-approved saltwater disposal wells in Mississippi and Arbuckle carbonates. Recent attempts to recomplete coal zones in slim-hole completions are having mixed results. The major restraints to coal-bed methane production are restricted to low permeability of the coals and engineering problems, not to the availability or gas content of the coals.

Water quality changes as a result of coalbed methane development in a Rocky mountain watershed  

SciTech Connect

Coalbed methane (CBM) development raises serious environmental concerns. In response, concerted efforts have been made to collect chemistry, salinity, and sodicity data on CBM produced water. However, little information on changes of stream water quality resulting from directly and/or indirectly received CBM produced water is available in the literature. The objective of this study was to examine changes in stream water quality, particularly sodicity and salinity, due to CBM development in the Powder River watershed, which is located in the Rocky Mountain Region and traverses the states of Wyoming and Montana. To this end, a retrospective analysis of water quality trends and patterns was conducted using data collected from as early as 1946 up to and including 2002 at four U.S. Geological Survey gauging stations along the Powder River. Trend analysis was conducted using linear regression and Seasonal Kendall tests, whereas, Tukey's test for multiple comparisons was used to detect changes in the spatial pattern. The results indicated that the CBM development adversely affected the water quality in the Powder River. First, the development elevated the stream sodicity, as indicated by a significant increase trend of the sodium adsorption ratio. Second, the development tended to shrink the water quality differences among the three downstream stations but to widen the differences between these stations and the farthest upstream station. In contrast, the development had only a minor influence on stream salinity. Hence, the CBM development is likely an important factor that can be managed to lower the stream sodicity. The management may need to take into account that the effects of the CBMdevelopment were different from one location to another along the Powder River.

Tracing coalbed natural gas-coproduced water using stable isotopes of carbon  

SciTech Connect

Recovery of hydrocarbons commonly is associated with coproduction of water. This water may be put to beneficial use or may be reinjected into subsurface aquifers. In either case, it would be helpful to establish a fingerprint for that coproduced water so that it may be tracked following discharge on the surface or reintroduction to geologic reservoirs. This study explores the potential of using {delta}{sup 13}C of dissolved inorganic carbon (DIC) of coalbed natural gas (CBNG) - coproduced water as a fingerprint of its origin and to trace its fate once it is disposed on the surface. Our initial results for water samples coproduced with CBNG from the Powder River Basin show that this water has strongly positive {delta}{sup 13}C(DIC) (12 parts per thousand to 22 parts per thousand) that is readily distinguished from the negative {delta}{sup 13}C of most surface and ground water (-8 parts per thousand to -11 parts per thousand). Furthermore, the DIC concentrations in coproduced water samples are also high (more than 100 mg C/L) compared to the 20 to 50 mg C/L in ambient surface and ground water of the region. The distinctively high {delta}{sup 13}C and DIC concentrations allow us to identify surface and ground water that have incorporated CBNG-coproduced water. Accordingly, we suggest that the {delta}{sup 13}C(DIC) and DIC concentrations of water can be used for long-term monitoring of infiltration of CBNG-coproduced water into ground water and streams. Our results also show that the {delta} {sup 13}C (DIC) of CBNG-coproduced water from two different coal zones are distinct leading to the possibility of using {delta}{sup 13}C(DIC) to distinguish water produced from different coal zones.

Optimization of coalbed-methane-reservoir exploration and development strategies through integration of simulation and economics  

SciTech Connect

The unique properties and complex characteristics of coalbed methane (CBM) reservoirs, and their consequent operating strategies, call for an integrated approach to be used to explore for and develop coal plays and prospects economically. An integrated approach involves the use of sophisticated reservoir, wellbore, and facilities modeling combined with economics and decision-making criteria. A new CBM prospecting tool (CPT) was generated by combining single-well (multilayered) reservoir simulators with a gridded reservoir model, Monte Carlo (MC) simulation, and economic modules. The multilayered reservoir model is divided into pods, representing relatively uniform reservoir properties, and a 'type well' is created for each pod. At every MC iteration, type-well forecasts are generated for the pods and are coupled with economic modules. A set of decision criteria contingent upon economic outcomes and reservoir characteristics is used to advance prospect exploration from the initial exploration well to the pilot and development stages. A novel approach has been used to determine the optimal well spacing should prospect development be contemplated. CPT model outcomes include a distribution of after-tax net present value (ATNPV), mean ATNPV (expected value), chance of economic success (Pe), distribution of type-well and pod gas and water production, reserves, peak gas volume, and capita. Example application of CPT to a hypothetical prospect is provided. An integrated approach also has been used to assist with production optimization of developed reservoirs. For example, an infill-well locating tool (ILT) has been constructed to provide a quick-look evaluation of infill locations in a developed reservoir. An application of ILT to a CBM reservoir is provided.

Mosquito larval habitat mapping using remote sensing and GIS: Implications of coalbed methane development and West Nile virus  

SciTech Connect

Potential larval habitats of the mosquito Culex tarsalis (Coquillett), implicated as a primary vector of West Nile virus in Wyoming, were identified using integrated remote sensing and geographic information system (GIS) analyses. The study area is in the Powder River Basin of north central Wyoming, an area that has been undergoing a significant increase in coalbed methane gas extractions since the late 1990s. Large volumes of water are discharged, impounded, and released during the extraction of methane gas, creating aquatic habitats that have the potential to support immature mosquito development. Landsat TM and ETM + data were initially classified into spectrally distinct water and vegetation classes, which were in turn used to identify suitable larval habitat sites. This initial habitat classification was refined using knowledge-based GIS techniques requiring spatial data layers for topography, streams, and soils to reduce the potential for overestimation of habitat. Accuracy assessment was carried out using field data and high-resolution aerial photography commensurate with one of the Landsat images. The classifier can identify likely habitat for ponds larger than 0.8 ha (2 acres) with generally satisfactory results (72.1%) with a lower detection limit of approximate to 0.4 ha (1 acre). Results show a 75% increase in potential larval habitats from 1999 to 2004 in the study area, primarily because of the large increase in small coalbed methane water discharge ponds. These results may facilitate mosquito abatement programs in the Powder River Basin with the potential for application throughout the state and region.
