Kathleen D. Gans Loren F. Metzger Janice M. Gillespie Sharon L. Qi 2018 Tabular Digital Data Menlo Park, California U.S. Geological Survey https://doi.org/10.5066/F72B8X8G 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, and charge balance. 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. Some total dissolved solids and well data in this data set were previously discussed in: Gillespie, J., Kong, D., and Anderson, S.D., 2017, Groundwater salinity in the southern San Joaquin Valley: AAPG Bulletin, v. 101, no. 8, 1239-1261: doi:10.1306/09021616043. Some produced water, sump pond samples, and refinery waste samples were previously discussed in: California Department of Water Resources, 1961, Effects of waste water disposal, Fruitvale Oil Field, Kern County.

Please see 'Distribution Info' for details. The data are best used to represent the range of inorganic chemical characteristics of produced waters in the Fruitvale oilfield. The data should be regarded with caution, particularly in representing the chemistry of produced water from any particular well, which may vary through time as a result of many factors.

The data represent unfiltered water samples to the best of our knowledge. Well identification information from the scanned lab sheets were compared to information found on the original scout cards, the Munger Map Books (1959, 1971, 1983, 1990), and the California Summary of Operations (1938). The quality of chemistry analyses were determined through charge balance calculations and percent error of these calculations. No formal logical accuracy tests were conducted. Commingled well samples from multiple wells were not included in this data set, with the exception of data from sumps and refinery wastes. Wells which could not be located by at least the Section of the Township and Range were not included. Where API numbers were not found, the latitude and longitude were calculated as the centroid of the Section or, if known, the Quarter Quarter Section of the Township and Range (calculations done on Earthpoint website) A formal accuracy assessment of the vertical positional information in the dataset is not applicable.
