THUMS B-767 Well Rework Program at Island White

THUMS Long Beach Co. is authorized to rework the existing injector well B-767 (API #0423722837) located offshore in the Wilmington Oil Field at Island White, California, under Permit #7052447 issued by the California Department of Conservation, Geologic Energy Management Division (CalGEM). The work involves repairing the well’s casing by running and cementing a casing sleeve to restore integrity without expanding its use or causing surface disturbance, aligning with Group B of CalGEM’s December 2023 rework exemptions guidance. This activity qualifies for categorical exemptions under the California Environmental Quality Act (CEQA), specifically Classes 1, 2, 4, 7, and 8 of 14 CCR §§ 15301, 15302, 15304, 15307, and 15308, as no unusual circumstances, sensitive environments, cumulative impacts, or historical resource concerns were identified to preclude exemption. The project is confined to subsurface operations at coordinates 33.7537219°N, -118.16017914°W within Section 08, Township 5S, Range 12W, B&M SB, with no planned changes to production capacity or surface infrastructure. The approval was certified on August 4, 2025, by Hafiz Ali Mohammed, Associate of Oil and Gas Engineer at CalGEM, and while the project is described as a forecast with no solicitation or contract number, it is not subject to federal procurement regulations or associated far clauses, payment systems, or contractor evaluation factors. There is no identified contract value, delivery schedule, or commercial terms, as the authorization stems entirely from state environmental and operational permitting under CalGEM oversight, with no formal contract award process or financial data disclosed.
