Fox Hills — Lower Hell Creek, Powder River Basin

Comments on Geologic Parameters

9 Hydrocarbon Production:

The Fox Hills has negligible volumes of hydrocarbon production in the Powder River Basin (Gluskoter and others, 1991), although distal equivalent sandstone facies encased in the Lewis Shale are productive in the southeast part of the basin (Mullen and Barlow and Haun, Inc., 1993).
