Historical produced water chemistry data compiled for the Fruitvale Oilfield, Kern County, California


Publication Date


Gans, K.D., Metzger, L.F., Gillespie, J.M, and Qi, S.L., 2018, Historical produced water chemistry data compiled for the Fruitvale Oilfield, Kern County, California: U.S. Geological Survey data release,


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 conductivity, [...]

The data were compiled by the USGS California Oil, Gas, and Groundwater (COGG) project as part of the California State Water Resources Control Board’s Regional Monitoring Program of water quality in areas of oil and gas production. The data were compiled for comparison to historical groundwater chemistry data and newly collected groundwater and produced water chemistry data to determine how oil and gas development has contributed to changes in groundwater quality at regional scales.
