Comments on Geologic Parameters

2 Permeability/Hydraulic Conductivity:

Several pieces of permeability information were gathered. Measurements from core data show intrinsic permeability for the Lyons between 0.1 and 3,000 md (Belitz and Bredehoeft, 1988). According to oil-field data in the subsurface, Lyons average permeability ranges from 0.9 to 88 md/ft (Levandowski and others, 1973). A transmissivity-simulated map (Belitz and Bredehoeft, 1988) was added to the GIS data base.
