USGS releases new national produced waters geochemical database

US: Scientists studying produced waters and their geochemical and environmental impacts have a powerful new tool in the newly released USGS Produced Waters Geochemical Database.

The database is an update of the 2002 USGS Produced Waters Database, adding more than 100,000 new samples with greater spatial coverage and from both conventional and unconventional oil and gas development.

This database is publicly available to all scientists and interested members of the public. Produced waters are those volumes of water that are typically recovered during oil and gas exploration, development, or production.

The database is designed to be dynamic and easily updated with new data or corrections as needed, and it is made up of 25 smaller databases, publications, and reports. The USGS Produced Waters Geochemical Database has data on a comprehensive list of chemicals, including major elements, trace elements, isotopes, and time-series data. The database lists seven different well types: conventional oil and gas, shale gas, tight oil, tight gas, coal bed methane, geothermal, and groundwater.
