THUMS B-301 Well Rework Program at Island White

The THUMS B-301 Well Rework Program, identified by permit number 7052448, involves the repair of one existing injector well located at Island White in the Wilmington Oil Field, offshore Los Angeles. The scope of work consists of repairing the wellbore casing by running and cementing a casing sleeve to restore structural integrity, after which the well will return to its original use. This project is managed by the California Department of Conservation, Geologic Energy Management Division (CalGEM), and is classified under Group B of the December 2023 CalGEM rework exemptions guidance. The project has been granted a Notice of Exemption from full environmental review under the California Environmental Quality Act (CEQA), citing categorical exemptions including Class 1 for existing facilities, Class 2 for replacement or reconstruction, and Class 4 for minor alterations to land. CalGEM has determined that the rework will result in negligible surface disturbance and no significant adverse environmental impacts. Administrative oversight and acceptance are handled by CalGEM in Long Beach, California, with the project certified on August 4, 2025. No specific pricing, federal acquisition regulations, or detailed delivery schedules were provided in the documentation.
