Pleasant Bayou No. 2 in Brazoria County, Texas, is the first well drilled and completed exclusively for evaluating the energy resoures from geopressured- geothermal zones. Water samples were obtained from 2 sandstone units in the geopressured zone (4,737 to 4,740 m and 4,453 to 4,471 m) during production tests of these units. Thirty formation-water samples also were obtained from normally and geopressured zones from 5 oil and gas fields located to the east and north of the test well in Brazoria and Galveston counties, Texas. All the samples are from sandstone units within the Frio Clay of Oligocene (.) age. Detailed chemical and isotope analyses of the waters show that the salinity of water in the geopressured zone from the oil and gas fields ranges from ca 55,000 to 75,000 mg/L dissolved solids--the salinity of water in the overlying normally pressured zone is lower and the 2 waters are not chemically compatible. All the formation waters are modified marine connate waters of the Na-Cl type.
