Coalbed gas currently accounts for about 6 percent of all US natural gas reserves. This 85-page US Geological Survey report describes the geology of these coalbed gas plays, discusses potential for future prospects and provides a brief history of coalbed gas exploration in the US. Copious information about many sedimentary basins, Cretaceous and Tertiary strata, and Laramide structures is included as part of the coalbed methane play analysis.
