Comments on Geologic Parameters

14 Porosity:

Thiel (1935), Hoholick and others (1984), Kreuztfeld (1982), and Barnes and others (1992) generated porosity data for the St. Peter Sandstone. The porosity-versus-depth curve of Hoholick and others (1984), in combination with the depth to top of the St. Peter Sandstone, was used to generate the porosity-distribution map in the GIS.
