Following the successful development of gas deposits associated with the coals of the Ferron Sandstone Member of the Mancos Shale in central Utah, several companies have begun looking for other economic coalbed-gas plays elsewhere in the state. Other prospective areas receiving industry attention include the Blackhawk Formation coals in the Book Cliffs coalfield, the coals of the Emery Sandstone Member of the Mancos Shale in the northern Wasatch Plateau coalfield, the Neslen Formation coals in the Sego coalfield, and the Dakota Formation coals in the Alton-Kolob coalfields. Thick coals with potential for gas exploration also occur in the Frontier and Adaville Formations that extend south from Wyoming into the Henrys Fork coalfield in northern Utah. The coal geology, organic maturity, and structural data for these various areas, as well as the level of company activity, are summarized for these various coalbed-gas play areas.
