Coalbed Methane Activities in the Energy Resources Program
Methane (natural gas), while frequently developed with petroleum, also occurs in association with coal. Coalbed methane accounts for about 7.5 percent of U.S. natural gas production. Recent U.S. estimates (Rice, 1997) indicate more than 700 trillion cubic feet (TCF) of coalbed methane gas in place, with over 100 TCF economically recoverable--a five-year supply at present rates of consumption.
USGS is developing models to accurately assess potential U.S. coalbed methane resources. These models evaluate:
-
Controls on the occurrence and recoverability of coalbed methane, including geologic, geochemical, engineering, technological and economic factors.
-
Resource development issues and environmental implications.
