Abstract

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 on the California Geologic Energy Management Division (CalGEM) website and have been compiled into computer readable numerical data sets. Other data, such as the stratigraphic markers, were generated by this project from interpreting borehole geophysical data. All the data analyzed are part of the California State Water Resources Control Board oil and gas Regional Monitoring Program and the USGS California Oil, Gas, and Groundwater (COGG) program.
