Comments on Geologic Parameters

12a Formation Temperature:

As part of their Gulf Coast Regional Aquifer System Analysis program, the U.S. Geological Survey (Pettijohn and others, 1988) mapped the distribution of temperature and salinity of formation water in several Tertiary subsurface intervals of the Gulf Coast region, including the Texas City area. These maps, including the middle and lower Miocene interval, are used for the GIS. Temperatures are reported in degrees Celsius, and temperatures in the Lagarto/Oakville interval typically range from 50 to 70 °C in the Texas City area.
