Oriskany Formation, Appalachian Basin (Western Pennsyslvania, Eastern Ohio, and Eastern Kentucky)

Comments on Geologic Parameters

2 Permeability/Hydraulic Conductivity:

Because of the high potential (in some areas) for natural gas production in the Oriskany Sandstone, there are a large number of reports, articles, and theses that report permeability in this stratigraphic interval (Headlee and Joseph, 1945; Harper and Patchen, 1996). Moreover, there are many geophysical logs available for the Oriskany Sandstone interval from which formation permeability can be calculated (Asquith, 1982) if a more detailed assessment is desired. For the GIS, we combined the sand/shale/limestone map of Diecchio and others (1984; their fig. 4) with permeability information from Headlee and Joseph (1945) and Harper and Patchen (1996) to characterize permeability distributions of the Oriskany Sandstone. Permeability was converted to hydraulic conductivity.
