The Coalbed Methane Resource of the Illinois Basin
SPE Unconventional Gas Recovery Symposium, 1980Abstract A program was initiated to determine the extent of the coalbed methane resource and the location of the most favorable resource areas within the Illinois basin, and to obtain a better understanding of the relationships between selected variables and the gas content of coals.

Coalbed Methane Potential of the Appalachians
SPE Unconventional Gas Recovery Symposium, 1982ABSTRACT Coal mines in the Appalachian Basin emit approximately 180 million cubic feet (MMcf) of high-quality methane into the atmosphere daily. The existence of mines in West Virginia, southwest Virginia, eastern Kentucky, Ohio, Pennsylvania, Tennessee, and Alabama with high gas emissions of over 100 thousand cubic feet per day (Mcf/d ...

Coal-forming environments have waxed and waned in extent since the mid-Paleozoic, having been associated with a restricted range of environments and hydrologic regimes during relatively brief geologic timespans. The three major episodes of coal genesis were the late Carboniferous and Permian, the late Jurassic through early Cretaceous, and the late ...

Coalbed methane extraction and utilization
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2003Coalbed methane (CBM) is the generic name for all methane of coal seam origin. It is a natural gas formed by geological, or biological, processes in coal seams and generally consists predominantly of methane, but may also contain some higher alkanes and non-combustible gases.

Methane has been observed in coalbeds since underground mining of that resource began. This gas, however, has only recently been recognized as an economically producible resource. Coal underlies approximately 360,000 sq mi of the conterminous United States but because of the paucity of data on coals deeper than 3,000 ft the size of the deep coal and ...

Enhanced coalbed methane recovery
The Journal of Supercritical Fluids, 2009The recovery of coalbed methane can be enhanced by injecting CO2 in the coal seam at supercritical conditions. Through an in situ adsorption/desorption process the displaced methane is produced and the adsorbed CO2 is permanently stored. This is called enhanced coalbed methane recovery (ECBM) and it is a technique under investigation as a possible ...

Coalbed Methane - A Decade of Success
SPE Annual Technical Conference and Exhibition, 1994Abstract Between 1983 and 1993, the coalbed methane (CBM) industry changed from a high cost operation to a competitive main line gas resource. In 1983, there were approximately 165 coalbed methane wells in the United States with an estimated total annual production of 6 BCF.

Coalbed Methane Potential Assessment
2018The potential of harnessing coal mine methane (CMM) from some gassy mines in coalfields of Damodar River Basin for its gainful utilization is described in this chapter. Opportunities of CMM recovery in some prospective areas, wherein coal mining will start in near future have also been discussed.
