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 oil and gas fields in the southwestern San Joaquin Vallley, 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 2021.

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (State Water Board) compiled and analyzed data for mapping groundwater salinity, characterizing aquifer systems, and documenting the effects of oil field water injection in the Elk Hills Elk Hills, Buena Vista, and Coles Levee Oil Fields, San Joaquin Valley, California. Data provided in this data release include borehole geophysical data, geochemical analyses of water samples, hydrologic data, geological formation depths, and information on observed well log resistivity anomalies—interpreted to be from injection for disposal of produced water from oil wells or from natural causes. The data reported here were...

This dataset contains geochemical and other information for 204 samples of produced water from the Fruitvale petroleum field. Produced water is water coexisting with oil and gas. The historical produced water chemistry data was compiled from preexisting datasets and scanned images into a numerical dataset to characterize produced water chemical characteristics. Each sample is identified by its API (American Petroleum Institute) number, excluding the state code, which is 04 in all California wells, latitude and longitude, well name, formation name, perforation interval, and date tested. The geochemical analyses include major ions, some minor ions, total dissolved solids (TDS), pH, specific gravity, resistivity, electrical...

Total volumes of produced water disposed at percolation and evaporation ponds for the Midway-Sunset and Buena Vista Oil Fields, Kern County, California were estimated for 1959-2021. Data were compiled from state and local agencies’ databases, including the California State Water Resources Control Board GeoTracker, California Integrated Water Quality System (CIWQS), and Ponds Status Report (2019); the California Geologic Energy Management Division (CalGEM) Well Production and Injection Database (1977-2017); and the Central Valley Regional Water Quality Control Board Pond List (updated February 11, 2021). For pond disposal facilities that receive produced water from multiple sources, volumes were estimated from cumulative...

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board compiled and analyzed data for the purpose of mapping groundwater salinity in selected oil and gas fields in California. The data for the Rosedale Ranch oil field include well construction data, digitized borehole geophysical data, geochemical analyses of water samples from oil and gas wells and groundwater wells, geological formation depths, and the groundwater total dissolved solids (TDS) calculations used in the accompanying manuscript. These data have been compiled from many sources and span several decades. The well construction data includes attributes such as the date drilling began (spud date), well depth,...

This data release contains groundwater elevation data and the associated model/code used to create groundwater elevation surfaces in and around select oil fields in California. The data and model provided here are intended to supplement interpretative manuscripts. Specific study areas will be added as Child Items found in this data release. Groundwater elevations are usually collected from individual wells at discrete times. However, we are often interested in looking at a continuous surface of groundwater levels for a variety of reasons including to examine potential gradients, or directions of groundwater flow. Therefore, we created continuous space-time models of groundwater elevations using a Gaussian process....

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board and the U.S. Bureau of Land Management compiled and analyzed data for mapping groundwater total dissolved solids (TDS) and characterizing clay layers and faults in the Poso Creek Oil Field in Kern County, California. Data for the Poso Creek Oil Field area include analyses of historical produced water samples from oil wells, borehole geophysical data, and geological formation depths. The data reported here are used in an accompanying interpretive manuscript that describes groundwater TDS, stratigraphic layers, and geologic structure in the study area. Some of these data were archived scanned pages in raster format...

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board compiled and analyzed data for mapping groundwater salinity and characterizing aquifer systems in and near selected oil and gas fields in California. Data for the Lost Hills, North Belridge, and South Belridge oil fields include production and injection volumes, oil show data, formation pressure data, digitized borehole geophysical data, geochemical analyses of produced water samples, geological formation depths, and geophysical data associated with estimating groundwater total dissolved solids (TDS) of formation water. All data reported here are used in an accompanying interpretive manuscript. These data have...
