Surface Casing Program at the Texas Commission on Environmental Previous HitQualityNext Hit (TCEQ): Fifty Years of Ground Previous HitWaterNext Hit Protection Recommendations for the Petroleum Industry

Robert J. Traylor
TCEQ, Austin, TX

In 1955 the Surface Casing Program began at a predecessor agency to TCEQ. This was a historic time for ground Previous HitwaterNext Hit protection in oil and gas operations in Texas. Both the petroleum industry and the Texas Railroad Commission (RRC) decided that the RRC had a conflict-of-interest in protecting ground Previous HitwaterNext Hit and regulating the petroleum industry. To add integrity to the RRC ground Previous HitwaterNext Hit protection program, the RRC changed rules to acquire geologic advice from geologists at the old Board of Previous HitWaterNext Hit Engineers on protected ground waters depths. The geological advisory role of the TCEQ Surface Casing Program and the RRC is unique for state agencies. Also, no other state addresses ground Previous HitwaterNext Hit protection with this checks-and-balances system. Three types of ground Previous HitwaterNext Hit Previous HitqualityNext Hit are designated by the Surface Casing Program for various oil and gas operations: fresh or superior Previous HitqualityNext Hit (TDS<1000 ppm), usable Previous HitqualityNext Hit (TDS<3000 ppm), and underground sources of drinking Previous HitwaterNext Hit (USDW) (TDS<10,000 ppm). These Previous HitwaterNext Hit Previous HitqualityNext Hit depths and isolations are determined from multiple data sources such as public supply and private Previous HitwaterNext Hit wells, Previous HitwaterNext Hit Previous HitqualityTop analyses, and more than 250,000 geophysical logs in the Surface Casing log library.
