Minor Alteration No. WA2025006 Chevron Kern River Wells Abandonment

Minor Alteration No. WA2025006 involves the abandonment of oil wells along the Kern River in Kern County, California, performed by Chevron Americas Exploration and Production Company. The project is overseen by the Central Valley Flood Protection Board and is categorized as a forecast with a performance location in Bakersfield, California. The work is exempt from the California Environmental Quality Act under a Class 1 categorical exemption as it consists of minor alterations to existing facilities without expanding their use. The scope of work requires the mobilization of a well rig to remove rods and tubing, followed by the use of a Coil Tubing Unit to clean the well to the bottom. The wells must be filled from the bottom to the surface with cement or zonite. Final requirements include cutting the casing five feet below the surface, tack-welding identification plates to the casing stubs, and restoring the sites to their original state using native soil with 95% compaction. The project is expected to be completed within a four-week timeframe.
