Hydrologic-Hydrochemical Characterization of Texas Gulf Coast Saline Formations Used for Deep-Well Injection of Chemical Wastes

摘要

About 70 percent of the Class I injection wells in the United States are located in the Gulf Coast. The report presents the results of investigations into fluid migration potential, direction and velocities in the regional hydrologic environment of the Texas Gulf Coast Tertiary formations, and geochemical interactions that may be occurring. The study focused on the frio formation as it is the target of a very large waste injection volume as well as a large database of formation pressures and water chemistry.
