THUMS D-623 Well Rework Program at Island Freeman

THUMS Long Beach Co. is conducting a rework program for one existing oil and gas well, identified as well D-623 (API #0423720806), located at Island Freeman in the Wilmington Oil Field, offshore Los Angeles. The project involves adding pay in the same zone to address well integrity issues and restore production capabilities through minor casing alterations, wellbore reconstruction, and the installation or removal of downhole equipment. This activity is governed by permit #7052493 and falls under Group A of the CalGEM rework exemptions guidance published in December 2023. The California Department of Conservation, Geologic Energy Management Division (CalGEM) has issued a Notice of Exemption for the project under the California Environmental Quality Act (CEQA). The rework is exempt from full environmental review based on categorical exemptions for existing facilities, replacement or reconstruction, and minor alterations to land, as the project is determined to have negligible environmental impact. While the project is listed as a forecast with a posted date of August 6, 2025, there are no specified contract values, federal acquisition regulation clauses, or defined performance schedules provided in the documentation. Regulatory oversight and acceptance are managed by the CalGEM Southern District office in Long Beach, California.
