Platforms Hogan and Houchin Plugging and Abandonment Project

The Platforms Hogan and Houchin Plugging and Abandonment Project involves the decommissioning of 74 oil and gas wells across two offshore platforms in the Carpinteria Field off the coast of California, with 39 wells at Platform Hogan and 35 at Platform Houchin. Work will proceed sequentially, beginning at Platform Hogan and moving to Platform Houchin after completion, due to limitations in specialized equipment. The project is expected to conclude at Platform Hogan by the end of 2027, with work at Platform Houchin extending an additional one to two years. Authorized activities include the installation and operation of a new portable crane with a Tier 4 Final diesel engine, replacement of the existing Platform Hogan South Unit Crane engine with a compliant Tier 4 Final unit, deployment of up to six diesel-powered prime engines on the abandonment rig for P&A operations, and the use of one additional diesel engine for emergency power during outages. Flaring limits at both platforms have been increased to accommodate well blowdowns and end-of-life abandonment procedures. All operations must comply with Santa Barbara County Air Pollution Control District rules, including Rule 331 sections D, E, G.1, I, and 206, as well as Part 70 Permit conditions related to fugitive emissions control and Leak Detection and Repair requirements. The project qualifies for a categorical exemption under the California Environmental Quality Act (CEQA) and operates under permits PTO 15962 01, PTO 15978 01, ATC 16435, ATC 16459, and ATC 16460, which collectively authorize the equipment modifications and emissions increases necessary for decommissioning. The Santa Barbara County Air Pollution Control District retains regulatory oversight, with key contacts for permitting, CEQA compliance, and engineering coordination provided, though no formal contract clause, pricing, payment, or procurement evaluation details are included in the documentation.
