The U.S. Geological Survey (USGS) has released its new Produced Waters Geochemical Database and Map Viewer, an online platform that provides valuable information on a comprehensive list of chemicals, including major elements, trace elements, isotopes, and time-series data.

The database is publicly available to all industry experts and interested members of the public and is a key resource for scientists studying produced waters and their geochemical and environmental impacts. Accordingly, it serves as an update of the 2002 USGS Produced Waters Database, adding more than 100,000 new samples with greater spatial coverage. The kind of well the sample originated from is important, as different well types involve different production methods and rock formations. The USGS Produced Waters Geochemical Database lists seven different well types: conventional oil and gas, shale gas, tight oil, tight gas, coal bed methane, geothermal, and groundwater.
