Platform Holly/Piers 421/Venoco Bankruptcy
Current Status
Plug and abandonment work on Platform Holly resumed earlier this month—528 days after the pandemic shut down this work. As an important milestone, Well 3242-6 became the first well plugged to surface this month. Staff continues to maintain and monitor Platform Holly and the onshore facilities to ensure public health and safety. In September, staff, ExxonMobil, and their subcontractors reactivated the rig equipment that was mothballed during the COVID-19 shutdown and a full 24-hour rig crew returned to the platform on October 1 in preparation for moving the rig onto the first well. Plug and abandonment is planned to continue uninterrupted until all wells are plugged, which is estimated to take approximately 12-18 months. Staff is collaborating closely with ExxonMobil, their subcontractors, and CalGEM to ensure that the work ahead is conducted safely, effectively, and efficiently, and to reduce costs where possible. Personnel transport to and from the Platform is proceeding from the Goleta pier and cargo operations are being conducted from the Carpinteria Pier and Port Hueneme.
Background
In April 2017, Venoco quitclaimed its interests in the South Ellwood Field leases, including Platform Holly and the Ellwood Beach pier leases near the City of Goleta. The quitclaims ended commercial oil and gas production in state waters in the Santa Barbara Channel and returned operational control of these assets to the Commission. California’s Coastal Sanctuary Act prohibits the Commission from issuing new offshore oil and gas leases.
The Commission selected Beacon West Energy Group, LLC as its contractor to operate and maintain Platform Holly and the Ellwood Onshore Facility. Beacon West, under the Commission’s oversight, began ensuring the security and safe daily operations and maintenance at Platform Holly and the Ellwood Onshore Facility in September 2017.
ExxonMobil, the successor in interest to the prior operator, Mobil Oil Corporation, and Venoco’s predecessor for these lease interests, agreed to fulfill its obligation to abandon the 30 wells on Platform Holly, seven of which were Venoco re-drilled wells and are state obligations, and the two near-shore wells on what was Oil & Gas Lease 421 in Goleta (Piers 421 wells).
The Piers 421 wells were successfully plugged and abandoned in 2019. Plug and abandonment work on Platform Holly began in October 2019, only to be halted in March 2020 due to the Covid-19 pandemic and related physical distancing requirements. The Commission maintained 24-hour staffing at Platform Holly and the Ellwood Onshore Facility during the hiatus to ensure health and safety, given the dangerous amounts of hydrogen sulfide gas that is present in the wells until they are fully plugged and abandoned.
Efforts to resume plug and abandonment work on Platform Holly are underway and active well work is expected to resume on September 30, 2021. Plug and abandonment operations are anticipated to continue through completion in early 2023, assuming there are no additional unanticipated delays.
In June 2021, the Commission issued a Notice of Preparation to decommission the PRC 421 wells. The Commission held public scoping meetings later that month and is now preparing an Environmental Impact Report. Piers 421 decommissioning work is anticipated to begin in Spring/Summer of 2022.
As for Platform Holly decommissioning, the Commission plans to hire an environmental consultant in early 2022 to conduct CEQA review. We anticipate that the CEQA process for Platform Holly decommissioning will start in mid-2022 and involve robust public and stakeholder outreach. The CEQA process will inform the ultimate decommissioning plan for Platform Holly, which will be subject to Commission review and approval at a public meeting.
