Abstract The rugged, mountainous Wasatch Plateau yields gas in the Clear Creek, Flat Canyon, Joes Valley, and Ferron fields. The first discovery in the area was at Clear Creek in 1951. Present production is about 10 million cu ft of gas a day. All the producing areas are on closed structural features, and the principal producing zone is the Upper Cretaceous Ferron Sandstone Member of the Mancos Shale. The most important field is Clear Creek, located on a regional uplift that has been transected by major faults that have formed a graben. There is a large structural closure against the west or basinward side of the fault. Tectonic activity during deposition of Ferron sandstone aided its development as a reservoir rock. The Ferron appears to have had two sources, one on the southwest and the other on the northwest. The sandstone derived from the northwest appears to have been more conducive to accumulation of gas. Future discoveries appear to depend on testing of undrilled structural closures; stratigraphic analyses of the Ferron, Dakota, Star Point, and Emery sandstones for flank traps; and deep drilling of the known porous Paleozoic rocks, principally the Mississippian limestones.
