Geologic assessment of natural gas from coal seams in the Piceance Basin, Colorado. Topical report, September 1985-September 1986. Final geologic report
To evaluate the natural gas potential of coal seams in the major coal groups of the Piceance Basin (Colorado), an analysis of the subsurface geology of the Black Diamond, Cameo, and Coal Ridge of the Iles and Williams Formations was completed along with new correlations of gas content to coal rank and depth. Natural gas in place is estimated to be 84 TCF (Cameo Group, 65 TCF; Coal Ridge Group, 10 TCF; and Black Diamond Group, 9 TCF). Within the Cameo Group, the A and D seams account for about half or 38 TCF of the gas in place. The most-concentrated areas of methane in place are in the east-central portion of the Piceance Basin around the Divide Creek Anticline and Grand Hogback Monocline, areas which have thick accumulations of high-rank coals and appear to have been tectonically altered.
