Summary

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, Gas, and Geothermal [...]

Purpose

The total well depths for groundwater wells were used to characterize the depth of groundwater resources in each field. Vertical proximity, which is the vertical distance between petroleum resource development and groundwater resources, was calculated by using these values in combination with other data. The locations of wells with depth data were used to calculate the density of water wells overlying and adjacent to each oil and gas field.
