Cape Fear Formation, South Carolina Coastal Plain (06)

Comments on Geologic Parameters

06 Continuity:

A number of studies present cross sections of the Cape Fear interval that include geophysical logs (gamma ray, spontaneous potential) (Colquhoun and others, 1983; Aucott and others, 1987; Temples and Waddell, 1996). These cross sections indicate that sands are generally discontinuous (R. Willoughby, South Carolina Geological Survey, personal communication, 2000). Brown and others, (1979; their table 7) determined that the thickest potential reservoir sand in the Cape Fear interval ranges from 40 to 58, with an average of 49. These thicker sands tend to be more continuous. For the GIS, we chose to use the thickness of reservoir sand as determined by Brown and others (1979).
