Coalbed methane (CBM) now accounts for nearly 10 percent of the gas production and dry gas reserves in the United States. Over 15,000 coalbed methane wells have been drilled, mostly in the Rocky Mountain region. CBM from Canada, Alaska and across the lower 48 will grow rapidly in the coming decade. A huge volume of this undeveloped gas will come from the many basins in which CBM plays are just emerging throughout North America.
