Coalbed methane (CBM) is a source of natural gas that is recovered by dewatering coal beds and collecting volatile compounds, such as methane, that are desorbed from the coal. Coalbed methane currently accounts for approximately 7% of U.S. natural-gas production (U.S. Energy Information... |

Between 1999 and 2007, the U.S. Geological Survey (USGS) investigated coalbed methane (CBM) resources in the Wyoming portion of the Powder River Basin. The study also included the CBM resources in the North Dakota portion of the Williston Basin of North Dakota and the Wyoming portion of the Green... |

the North Slope, Alaska.
Methane and other gases, while frequently produced with petroleum, also occur in association with coal. Coalbed gas accounts for about eight percent of U.S. natural gas production. U.S. estimates (Rice, 1997) indicate more than 700 trillion cubic feet (TCF) of coalbed gas in place, with over 100 TCF economically recoverable--a five-year supply at present rates of consumption.
The USGS Energy Resources Program assesses potential U.S. coalbed gas resources including controls on the occurrence and recoverability, (including produced water) and geologic, geochemical, engineering, and technological factors.

Environmental Considerations
Environmental Considerations
The USGS Energy Resources Team examines environmental considerations with coalbed natural gas development (CBNG) nationwide. A major portion of this is on water co-produced with CBNG, which is provided in the Energy Program’s "Produced Waters" topic.
