Comments on Geologic Parameters

2 Permeability/Hydraulic Conductivity:

Permeability data are very limited for the Fox Hills Sandstone. Mullen and Barlow and Haun, Inc. (1993), indicated a permeability of 49 md of the Fox Hills Sandstone in the West Side Canal reservoir in Carbon County in the Greater Green River Basin. By comparison with similar facies in the Powder River Basin, a typical permeability value of 50 md can be inferred for the Fox Hills Sandstone there, but the permeability distribution is unknown.
