Rework to Repair Well Casing on Island Grissom within THUMS Operating Area

THUMS Long Beach Company is authorized to rework existing oil well A-868, API number 0423700611, located offshore on Island Grissom within the Wilmington Oil Field in California. The primary objective of the project is to address well integrity concerns by repairing the casing through the installation and cementing of a 5½-inch casing sleeve in the damaged section of the wellbore, restoring the well to its original operational capacity without expanding its footprint or increasing production. This work is classified as maintenance of an existing facility and is exempt from full environmental review under California Environmental Quality Act (CEQA) categorical exemptions, specifically Classes 1, 2, 4, 7, and 8, which cover repair and replacement of existing infrastructure, minor land alterations, and protection of natural resources. The project is regulated and approved by the California Department of Conservation, Geologic Energy Management Division (CalGEM), which serves as the sole authority for permitting and acceptance of the work at the well site. The project is not governed by federal acquisition regulations, and no contract clauses, pricing, payment terms, delivery schedules, or evaluation criteria are included in the documentation, as it functions as an environmental notice of exemption rather than a federal procurement instrument. No contract number, solicitation reference, or cost estimates are provided. The responsible party for oversight and final acceptance is CalGEM, with Gregory S. Berg serving as the certified official who determined eligibility for the CEQA exemption. The work is confined to the existing well pad on Island Grissom in Los Angeles County and must comply with CalGEM regulations (14 CCR §§ 1684.1 and 1684.2) and state health and safety protections outlined in PRC § 3280(b). The project involves no new construction, no expansion of facilities, and no disturbance of previously undisturbed areas, ensuring alignment with the regulatory framework designed to streamline minor, non-expansive well maintenance activities. All communications and submissions regarding the project should be directed to CalGEM’s Southern District Office in Long Beach, California.
