Shallow Tertiary Gas Production, Powder River Basin, Wyoming

Arthur G. Randall

Abstract

Since 1916, at least 14 shallow gas fields in the Wyoming portion of the Powder River Basin have been discovered. The depths of the seven producing zones range from 177 ft (54 m) to 556 ft (169 m). The initial production rates vary from 6 to 2,600 MCFGPD.

The producing sandstones occur between thick coal beds in the Tongue River Member of the Fort Union Formation, which is Paleocene in age. One field has produced considerable gas from the Wasatch Formation of Eocene age.

The traps are formed by a variation of porosity and permeability conditions within a structural framework. Over 1.5 billion cubic feet of methane gas has been produced over an area of 75 mi (120 km) by 100 mi (161 km).

As of December 31, 1988, the Oedekoven Field in T55N, R73W has produced over 916 MMCF of 95 percent methane gas from the Fort Union Formation.
