Produced water disposal at percolation and evaporation ponds in and near oil fields in the southwestern San Joaquin Valley, California (ver. 2.0, October 2024)
The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board compiled and analyzed data on water production and produced water disposal on land at Midway-Sunset, Buena Vista, Elk Hills, McKittrick, Cymric, South Belridge, North Belridge, and Lost Hills Oil Fields in the southwestern San Joaquin Valley (SWSJV), Kern County, California. Data were compiled from information in state and local agencies databases and cover a period of record ranging from the early 1900's through 2019. Datasets include shapefiles with locations of retention ponds and natural drainage systems used for produced water disposal, total volumes of produced water disposed of at percolation and evaporation...

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water and gas samples in the Midway-Sunset, Poso Creek, and Buena Vista Oil Fields in Kern County in 2020 and 2021. Sampled sites included oil wells; injectate from tanks, pipelines, and injection wells where produced water from many wells, after removal of oil, is stored or transported prior to underground injection; and integrated produced water from many oil wells collected from pipelines before oil removal. This digital dataset contains the site information, analyzing laboratories and methods, and water and gas chemistry and quality-control results for these samples. Chemistry results include...

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (Water Board) collected produced water and casing gas samples from petroleum wells and other oil-field sites in selected oil fields in the southern San Joaquin Valley in Kern County in 2016 and 2017. The samples were collected as part of the Water Boards Regional Groundwater Monitoring Program (RMP) of Water Quality in Areas of Oil and Gas Production. Samples included produced water and casing gas collected from oil wells, produced water collected from surface produced water disposal ponds, and injectate stored in tanks planned for underground injection. Samples were collected from the Fruitvale oil field on...
