Comments on Geologic Parameters

12b Formation Pressure:

Tucker and Kidd (1973; their fig. 6) provided a summary of fluid pressure versus depth relationships for the coastal-plain strata of southwest Alabama. To determine pressure distribution within the Tuscaloosa Group, we used Tucker and Kidd's (1973) gradient of 0.482 psi/ft and the map showing depth to the middle Tuscaloosa Group (Moffet and others, 1984a).
