Depths to top of perforated intervals and base of freshwater for oil and gas production wells in California
During 2014-2016, the depth to top of perforated intervals and depth to base of freshwater for oil and gas production wells in California were extracted from well records maintained by the California Division of Oil, Gas, and Geothermal Resources (DOGGR). Well records including geophysical logs, well history, well completion reports, and correspondences were viewed on DOGGR's Well Finder website at https://maps.conservation.ca.gov/doggr/wellfinder/. This digital dataset contains 3,505 records for production wells, of which 2,964 wells have a recorded depth to top of perforated intervals and 1,494 wells have a recorded depth to base of freshwater. Wells were attributed with American Petroleum Institute (API) numbers,...
Effects of brine injection wells, dry holes, and plugged oil/gas wells on chloride, bromide, and barium concentrations in the Gulf Coast Aquifer, southeast Texas, USA
In 2014, total well depths for groundwater wells in California were extracted from digital copies of well completion reports provided to the U.S. Geological Survey by the California Department of Water Resources (DWR). This digital dataset contains 16,912 well depths for domestic, municipal, irrigation, industrial, and agricultural wells that were overlying oil and gas fields or within 5 kilometers of a field boundary. Wells were attributed with approximate location, well use, and depth using information provided by DWR, and were attributed with land surface elevations using the California National Elevation Dataset. Wells were also attributed with the nearest oil and gas field using the California Division of Oil,...
Depths to top of perforated intervals and base of freshwater for oil and gas injection wells in California
The depth to top of perforated intervals and depth to base of freshwater for oil and gas injection wells in California were compiled from an Access database provided by the California Division of Oil, Gas, and Geothermal Resources (DOGGR) in February 2015 as a retrieval from the California Well Information Management System (CalWIMS) database for Underground Injection Control (UIC) wells. This digital dataset contains 19,322 records for injection wells, of which 17,278 wells have a recorded depth to top of perforated intervals and 5,248 wells have a recorded depth to base of freshwater. The original dataset included the depths, American Petroleum Institute (API) numbers, oil and gas field, and well location. Wells...
Data analyzed for the preliminary prioritization of California oil and gas fields for regional groundwater monitoring
There are 487 onshore oil and gas fields in California encompassing 3,392 square miles of aggregated area. The California State Water Resources Control Board (State Water Board) initiated a Regional Monitoring Program (RMP) in July 2015, intended to determine where and to what degree groundwater quality may be at potential risk to contamination related to oil and gas development activities including well stimulation, well integrity issues, produced water ponds, and underground injection. The first step in monitoring groundwater in and near oil and gas fields is to prioritize the 487 fields using consistent statewide analysis of available data that indicate potential risk of groundwater to oil and gas development....

Produced water chemistry data for samples from four petroleum wells, Southern San Joaquin Valley, California, 2014
The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water samples from four petroleum wells in the southern San Joaquin Valley on November 5, 2014. This digital dataset contains the site information, analyzing laboratories and methods, and water chemistry and quality control results for these samples. Water chemistry results include concentrations of dissolved hydrocarbon gases and their isotopic composition; concentrations of inorganic constituents including salinity, major ions, and nutrients; dissolved organic carbon; and stable isotopes of water and strontium dissolved in water. Samples were analyzed by 5 laboratories operated or contracted...
