In the Piceance basin of western Colorado, gas has been found in several sandstone zones in the Upper Cretaceous (upper part of Mancos and Mesaverde) and Tertiary (Fort Union, Wasatch, and Green River) beds. The first well in the basin was drilled in 1890 and the first important gas discovery was made in 1930, but lack of outlet retarded gas exploration until recent years. All producing beds in the Upper Cretaceous and Tertiary section have marked facies changes which are predominantly important in the trapping of gas, although some anticlinal features also are influential. Total gas production from these beds to Jan. 1, 1966, was about 71 billion cu ft, and established reserves are probably nearly 12 times that quantity. Future prospects for the basin as a source of natural gas are good.
