U.S. Geological Survey National Produced Waters Geochemical Database v2.3 (superseded by ver. 3.0, December 2023)

Please note: This product is superseded by the ver. 3.0, December 2023 product provided within the 'Data' tab below.
During hydrocarbon production, water is typically co-produced from the geologic formations producing oil and gas. Understanding the composition of these produced waters is important to help investigate the regional hydrogeology, the source of the water, the efficacy of water treatment and disposal plans, potential economic benefits of mineral commodities in the fluids, and the safety of potential sources of drinking or agricultural water. The U.S. Geological Survey National Produced Waters Geochemical Database v2.3 (superseded by ver. 3.0, December 2023) is an updated compilation of geochemical and related information for water from oil and gas wells in the United States. It includes identification and location information, well descriptions, dates, rock properties, physical properties of the water, inorganic chemistry, organic chemistry, and isotopes. Disclaimer for Provisional Database The data you have secured from the U.S. Geological Survey (USGS) National Produced Waters Geochemical Database v2.3 (superseded by ver. 3.0, December 2023) are provisional and subject to revision.
