Available in PDF, EPUB and Kindle. Book excerpt: A two-year project was conducted to gather data that would assist in the evaluation of the methane potential of the coal beds of Colorado. It was found that a number of closed underground coal mines in the State had reported gassy conditions or had experienced fires and explosions of varied intensity and frequency. The majority of such occurrences have been in those areas characterized by coals of relatively low (i.e., below 31%) volatile matter (VM) content. The south half of the Raton Mesa coal region (Las Animas County) and the southeastern part of the Unita region (in Gunnison and Pitkin Counties) contain coals with the lowest percentages of VM, the gassiest producing mines, and the highest grade coking coal in the State. Five active mines in Pitkin County presently are emitting a total of over 8 million cu ft of methane per day. These mines produce the highest quality metallurgical-grade coal in the western US (high-volatile A and medium-volatile bituminous). The gassy coals in these two regions range from Late Cretaceous to Paleocene in age and usually occur in areas related to igneous activity of late Tertiary age. The VM percentages of Colorado coals can be used, with some caution, to determine their potential methane content. Additional desorption measurements and coal analyses are needed to more accurately predict the effects of rank and depth of occurrence on the methane content of coals in the State.

This book was released on 2010-11-15 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In some coalbeds, naturally occurring water pressure holds methane-the main component of natural gas-fixed to coal surfaces and within the coal. In a coalbed methane (CBM) well, pumping water from the coalbeds lowers this pressure, facilitating the release of methane from the coal for extraction and use as an energy source. Water pumped from coalbeds during this process-CBM 'produced water'-is managed through some combination of treatment, disposal, storage, or use, subject to compliance with federal and state regulations. CBM produced water management can be challenging for regulatory agencies, CBM well operators, water treatment companies, policy makers, landowners, and the public because of differences in the quality and quantity of produced water; available infrastructure; costs to treat, store, and transport produced water; and states' legal consideration of water and produced water. Some states consider produced water as waste, whereas others consider it a beneficial byproduct of methane production. Thus, although current technologies allow CBM produced water to be treated to any desired water quality, the majority of CBM produced water is presently being disposed of at least cost rather than put to beneficial use. This book specifically examines the Powder River, San Juan, Raton, Piceance, and Uinta CBM basins in the states of Montana, Wyoming, Colorado, New Mexico, and Utah. The conclusions and recommendations identify gaps in data and information, potential beneficial uses of CBM produced water and associated costs, and challenges in the existing regulatory framework.

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.
