Tuscaloosa Group, Alabama Gulf Coastal Plain (12a)

Comments on Geologic Parameters

12a CO2 Solubility Brine: Formation Temperature:

Formation temperature. In their summary report of geothermal data for southwest Alabama, Wilson and Tew (1985) inferred that geothermal gradients for the Gulf Coastal Plain strata are low to moderate. We used figure 10 of Wilson and Tew (1985) to determine a geothermal gradient of 1.3 °F/100 ft for the Tuscaloosa Formation in the Mobile area. To derive temperatures we combined the temperature gradient with the depth to the middle Tuscaloosa Group mapping horizon by Moffet and others (1984a).
