Summary:Detailed chemical analyses of 120 formation-water samples from 25 oil and gas fields in coastal Texas and Louisiana show that the salinity of water in the geopressured zones ranges from about 10,000 to 270,000 mg/liter dissolved and may be higher or lower than the salinity of water in the normally pressured zones. The formation waters in the geopressured zones are most probably modified connate waters representing the original marine water of deposition. The chemical composition of these waters, however, is markedly different from that of ocean water. The differences in composition resulted from physical and chemical interactions between water and sediments. (Woodard-USGS)
