The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water samples for analysis of volatile organic compounds (VOCs) in the eight California oil fields of Fruitvale, Lost Hills, North Belridge, Orcutt, Placerita, South Belridge, Midway-Sunset, and Buena Vista from 2016 to 2020. 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; integrated produced water from many oil wells collected from pipelines before oil removal; and surface disposal ponds where produced water, after removal of oil, is disposed...

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water and casing gas samples from oil wells and injectate stored in surficial tanks planned for underground injection in the Orcutt oil field in Santa Barbara County in 2018. Samples were collected from the Orcutt oil field on February 6th and February 7th, 2018. 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 concentrations of dissolved noble and hydrocarbon gases and their isotopic composition; concentrations of inorganic constituents including salinity,...

In cooperation with the California State Water Resources Control Board Oil and Gas Regional Groundwater Monitoring Program the U.S. Geological Survey collected and analyzed groundwater and associated quality control (QC) samples to assess regional groundwater quality overlying and adjacent to the Orcutt Oil Field during September 2017 through March 2018. Groundwater samples were collected from 15 groundwater monitoring, irrigation and production wells located within a three-mile buffer zone overlying and surrounding the Orcutt Oil Field administrative boundary in Santa Barbara County, California. Samples were collected using established groundwater data-collection protocols and procedures. Samples were analyzed...
