Article Thumbnail Image Natural gas is an important component of the energy mix in the United States, producing greater energy yield per unit weight and less pollution compared to coal and oil. Most of the world’s natural gas resource is thermogenic, produced in the geologic environment over time by high temperature...

Article Thumbnail Image Coal formation dewatering at a site in the Powder River Basin was associated with enhanced potential for secondary biogenic methane determined by using a bioassay. We hypothesized that dewatering can stimulate microbial activity and increase the bioavailability of coal. We analyzed one dewatered and...

Article Thumbnail Image This report discusses the geologic framework and petroleum geology used to assess undiscovered petroleum resources in the Bohaiwan basin province for the 2000 World Energy Assessment Project of the U.S. Geological Survey. The Bohaiwan basin in northeastern China is the largest petroleum-producing...

Article Thumbnail Image Domestic oil and gas production and clean water are critical for economic growth, public health, and national security of the United States. As domestic oil and gas production increases in new areas and old fields are enhanced, there is increasing public concern about the effects of energy...

Article Thumbnail Image 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...

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

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.
