Comments on Geologic Parameters

2 Permeability/Hydraulic Conductivity:

Vugrinovich (1986) stated that core analyses near the rim of the basin "show high permeabilities," but "the only drill stem test of the Mt. Simon in the central basin indicated low permeability over approximately 94 meters of section." Briggs (1968, p. 139) stated that "as the proportions of limestone, dolomite, and carbonate-mineral cement increase toward the south and east in the Michigan Basin, the porosity and permeability of the sandstone should decrease proportionally." However, we were only able to obtain permeability data for one well (Briggs, 1968), and we utilized the average permeability in the Mt. Simon for that well.
