This book was released on 2013-03-09 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coalbed gas has been considered a hazard since the early 19th century when the first mine gas explosions occurred in the United States in 1810 and France in 1845. In eastern Australia methane-related mine disasters occurred late in the 19th century with hundreds of lives lost in New South Wales, and as recently as 1995 in Queensland's Bowen Basin. Ventilation and gas drainage technologies are now in practice. However, coalbed methane recently is becoming more recognized as a potential source of energy; rather than emitting this gas to the atmosphere during drainage of gassy mines it can be captured and utilized. Both economic and environmental concerns have sparked this impetus to capture coalbed methane. The number of methane utilization projects has increased in the United States in recent years as a result, to a large extent, of development in technology in methane recovery from coal seams. Between 1994 and 1997, the number of mines in Alabama, Colorado, Ohio, Pennsylvania, Virginia, and West Virginia recovering and utilizing methane increased from 1 0 to 17. The Environmental Protection Agency estimates that close to 49 billion cubic feet (Bet) of methane was recovered in 1996, meaning that this amount was not released into the atmosphere. It is estimated that in the same year total emissions of methane equaled 45. 7 Bcf. Other coal mines are being investigated at present, many ofwhich appear to be promising for the development of cost-effective gas recovery.

Available in PDF, EPUB and Kindle. Book excerpt: Characterization of gas sorption behavior on coals plays an important role on coalbed methane (CBM) and CO2-enhanced CBM industry. In this study, the excess adsorption capacities were estimated for four coal samples with different ranks including San Juan sub-bituminous coal, Pittsburgh No. 8 bituminous coal, Hazleton anthracite and Good Spring anthracite by the volumetric adsorption experimental method. Adsorption and desorption isotherms of methane and CO2 were directly measured for these four coal samples. Langmuir based models and Dubinin-Astakhov (D-A) based models were used to model adsorption behavior of both methane and CO2. The experimental results showed that CH4/CO2 excess adsorption capacity ratio varied from 1:1.1 to 1:1.6 at maximum equilibrium pressure on these coals. Higher rank coals have higher excess adsorption capacities than lower rank coals across the experimental pressure range. Hysteresis of CO2 is discernable and larger than methane for all coals. Higher rank coals have negligible methane hysteresis but larger CO2 hysteresis than lower rank coals. From the modeling results, maximum CO2 adsorption capacities are larger than methane capacities for all coals. In general, D-A based models were modeled better than Langmuir based models for these coals. Added k term reduced modeling error for both Langmuir and D-A series models. In addition, the modified Langmuir model-1 have relatively high errors for all coal samples.

Book excerpt: Coal Bed Methane: Theories and Applications, Second Edition, captures the full lifecycle of a coal bed methane well and offers petroleum geologists and engineers a single source for a broad range of coal bed methane (CBM) applications. The vast coal resources in the United States continue to produce tremendous amounts of natural gas, contributing to a diverse range of energy assets. This book addresses crucial technical topics, including exploration and evaluation of coal bed reservoirs, hydraulic fracturing of CBM wells, coal seam degasification, and production engineering and processing, among others. The book also covers legal issues and permitting, along with an economic analysis of CBM projects. This new edition includes information on new and established research and applications, making it relevant for field geologists and engineers, as well as students. Edited by a team of coal bed methane experts from industry, academia and government with more than 100 years of combined experience in the field Contains more than 150 figures, photographs and illustrations to aid in the understanding of fundamental concepts Presents the full scope of improvements in U.S. energy independence, coal mine safety and greenhouse gas emissions

This book was released on 1986 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1972, the Bureau of Mines developed a direct-method test for measuring the gas content of virgin coal core samples for coal mine health and safety considerations. Since that time, approximately 1,500 coal samples from more than 250 coalbeds in 17 States have been collected for gas content determination. The gas content data, when combined with geologic and engineering studies, can be used as a basis for a preliminary estimate of mine ventilation requirements, and to determine if methane drainage in advance of mining should be considered. The data are also critical in delineating coalbed methane resources and in utilization feasibility studies. This report makes the Bureau's extensive data base of gas content data more readily available to the coal and gas industries. The data are presented in tabular form, alphabetically by coalbed name and by State. The components of the total gas content (lost, desorbed, and residual gas) are given, Location (State and county), sample depth, coalbed or formation name, and coal rank are included for geographic and geologic identification.

Book excerpt: The formation and retention of methane in coalbeds was studied for ten Utah coal samples, one Colorado coal sample and eight coal samples from the Argonne Premium Coal Sample Bank. Methane gas content of the Utah and Colorado coals varied from zero to 9 cm3/g. The Utah coals were all high volatile bituminous coals. The Colorado coal was a gassy medium volatile bituminous coal. The Argonne coals cover a range or rank from lignite to low volatile bituminous coal and were used to determine the effect of rank in laboratory studies. The methane content of six selected Utah coal seams and the Colorado coal seam was measured in situ using a special sample collection device and a bubble desorbometer. Coal samples were collected at each measurement site for laboratory analysis. The cleat and joint system was evaluated for the coal and surrounding rocks and geological conditions were noted. Permeability measurements were performed on selected samples and all samples were analyzed for proximate and ultimate analysis, petrographic analysis, 13C NMR dipolar-dephasing spectroscopy, and density analysis. The observed methane adsorption behavior was correlated with the chemical structure and physical properties of the coals.
