Comments on Geologic Parameters

8 Continuity of Top Seal:

As discussed earlier, local faulting significantly influences the continuity of the Tertiary strata in the Texas City area, including the Burkeville confining layer. Baker (1986) reported that the Burkeville shale is generally thick enough not to be completely offset by faults, and therefore this interval remains an effective seal. A map showing the elevation at the approximate base of the Burkeville confining unit, as mapped by Ambrose (1990), was selected for use in the GIS because it highlights the importance of faulting and amount of offset associated with the top seal
