The U.S. state that produces the most coalbed methane is Wyoming.

Wyoming is the leading producer of coalbed methane (CBM) in the United States. Coalbed methane is a natural gas found in coal seams, and Wyoming's vast coal reserves, particularly in the Powder River Basin, make it an ideal location for CBM extraction. This region has been a major contributor to the country's natural gas production, with significant infrastructure in place to extract, process, and transport coalbed methane. Wyoming's production of CBM plays a key role in the state's energy economy.
