Enhanced Coalbed Methane Recovery
SPE Annual Technical Conference and Exhibition, 1990Abstract At present, coalbed methane is being recovered by means of reservoir pressure depletion. While this method is simple and effective, it is not efficient. Reduction in reservoir pressure deprives the fluids of the energy necessary to flow to the wellbore.

Coalbed Methane Simulator Development for Improved Recovery of Coalbed Methane and CO2 Sequestration
Proceedings of SPE Asia Pacific Oil and Gas Conference and Exhibition, 2005Proposal Sequestration of CO2 in deep unmined coal seams is currently under development for improved recovery of coalbed methane (ICBM) as well as permanent storage of CO2. Recent studies have shown that CO2 displaces methane by adsorbing more readily onto the coal matrix compared to other greenhouse gases, and could therefore contribute

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.

Abstract The commercial extraction of methane from coal beds is now well established in a number of countries throughout the world, including the USA, Australia, China, India and Canada. Because coal is almost pure carbon, its reservoir character is fundamentally different to conventional gas plays. Coalbed methane (CBM) forms as either biogenically-

Methane Recovery And Utilization From Coalbeds
SPE Annual Technical Conference and Exhibition, 1979Abstract Unconventional sources of natural gas already provide over 0.03 Tm3 (1 Tcf) annually to the domestic gas provide over 0.03 Tm3 (1 Tcf) annually to the domestic gas production and could ultimately provide a much larger production and could ultimately provide a much larger share of the natural gas supply.

The Sedimentary Control of Accumulation of Coalbed Methane in Hancheng Coalbed Methane Field
Applied Mechanics and Materials, 2013This paper discusses how sedimentary controls on accumulation of coal and coalbed methane in Hancheng CBM field. Two major coal-bearing strata include the Upper Carboniferous Taiyuan formation (a marine and terrestrial sedimentation) and the Lower Permian Shanxi formation (a terrestrial sedimentation).

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 ...

Coalbed Methane Modelling Best Practices
International Petroleum Technology Conference, 2013Abstract Determining the potential range of recoverable volumes for a Coalbed Methane (CBM) prospect is a necessary precursor to a successful development plan. Several key best practices were incorporated into a workflow to consistently assess the CBM potential of numerous prospective areas.

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 ...
