Tuscaloosa Group, Alabama Gulf Coastal Plain (14)

Comments on Geologic Parameters

14 Porosity:

Porosity data come from two sources, hydrocarbon and waste-disposal-potential assessments (Tucker and Kidd, 1973; Mancini and others, 1987). The data from Tucker and Kidd (1973; their table 2) are primarily used for the GIS. The data in the GIS are ranges of their data. A large number of geophysical logs that penetrate the Tuscaloosa Group are available. From these logs, it would possible to construct a more accurate spatial distribution of porosity, if CO2 sequestration in the area becomes a serious possibility.
