Comments on Geologic Parameters

12c Formation Water Salinity:

As part of their Gulf Coast Regional Aquifer System Analysis program, the U.S. Geological Survey (Pettijohn and others, 1988) mapped temperature and salinity of formation water in several Tertiary subsurface intervals of the Gulf Coast region, including the Texas City area. These maps include the middle and lower Miocene interval and are used for the GIS. Salinities are reported in milligrams per liter, and brine concentrations in the Lagarto/Oakville interval typically range from 35,000 to 150,000 mg/L in the Texas City area.
