CO2 sequestration enhances coalbed methane production
, 2013 Since 1980s, petroleum engineers and geologists have conducted researches on Enhanced Coalbed Methane Recovery (ECBM). During this period, many methods are introduced to enhance the production of coalbed methane. One of the methods called CO2-ECBM, which

Removing methane (degasification) from the Pocahontas No. 4 coalbed in southern West Virginia [PDF]
"Tests were conducted in the Pocahontas No. 4 coalbed in southern West Virginia to determine if successful degasification techniques, developed during an earlier study in the Pittsburgh coalbed, would be effective in removing methane from those usually ...

Methane and dust controls for longwalls : Pocahontas no.3 coalbed, Grundy, Virginia [PDF]
"The periphery of longwall panels in the Pocahontas No. 3 Coalbed is characterized by a zone of reduced permeability that inhibits the natural drainage of methane. A residual gas pressure of 105 psig was measured after 1 year in an isolated block of coal

Numerical simulation of hydraulic fracturing coalbed methane reservoir
, 2014 Some coal seam is well known for its three low characteristics: low permeability, low reservoir pressure and low gas saturation. Thus stimulation measures must be taken during coalbed methane development stage to enhance its recovery.
