ABSTRACT: Coal-bed methane in Utah, New Mexico, Colorado, and Wyoming: Resources, Reserves, and Production

Coal-bed methane reserves of 10 tcf, in-place resources up to 250 tcf, and dramatically increased production rates from Cretaceous and Tertiary formations affirm the importance of the Rocky Mountain gas province well into the 21st century. These resources have been calculated for the individual states and basins using a variety of criteria and methods and the resource numbers are not necessarily comparable.

The Book Cliffs, Emery, Wasatch Plateau, Kaiparowits Plateau, and Sego coal fields in Utah contain a coal-bed methane resource of 10.4 tcf. The Book Cliffs and Emery coal fields contain 8.3 tcf or 80% of this resource. The San Juan basin, New Mexico and Colorado, has 10 tcf (reserves), 40 tcf (resources) in the Fruitland Formation, and 28 tcf (resources) in the Menefee Formation. The Raton basin, Colorado and New Mexico, has 10.2 tcf of resources in the Raton and Vermejo Formations. The Piceance and Sand Wash basins in Colorado have estimated resources of more than 96 tcf. The Powder River, Green River, Hams Fork, Wind River, Hanna, Rock Creek, and Bighorn coal fields in Wyoming have resources of 54.4 tcf. The Powder River, Wind River, Green River, and Hams Fork coal fields contain 87 of this resource.

In August, 1992, coal-bed methane production accounted for 49% of all gas produced from the San Juan basin (New Mexico) and 30% of all New Mexico production. For 1991, coal-bed methane production in Colorado from the San Juan and Piceance basins was 16% of all Colorado gas production.
