The Case for Reefing California Platforms by John Smith

Environmental groups like the Environmental Defense Center and Get Oil Out continue to oppose converting the jackets of California oil and gas platforms to artificial reefs despite scientific studies (Claisse et al. 2014) showing “oil and gas platforms off the coast of California have the highest secondary fish production per unit area of seafloor of any marine habitat that
has been studied.

Another important factor environmental groups and the 2023 BOEM Programmatic EIS for Decommissioning failed to consider and acknowledge is the huge amount of air emissions that would be released by world-class heavy lift vessels like the Thialf or Balder Semi-submersible Crane Vessels (SSCVs) that would be required to safely and efficiently remove the large federal OCS platforms like Harvest, Hermosa, and Hidalgo (HHH). The HHH platforms are in waters depths ranging from 430-675 feet and have combined deck and jacket weights ranging from 20,000 – 25,000 tons. In comparison, the wrought iron structure of the Eiffel Tower weighs about 8,000 tons.

The SSCVs and accompanying Anchor Handling Tugs (AHTs) used to remove the HHH platforms will likely to be mobilized from distant locations like the North Sea or Gulf of America where they typically operate. Because SSCVs like the Thialf and Balder are too large to enter the Panama Canal, this would involve a 20,000 nautical mile roundtrip voyage around the tip of South America.

Three to four campaigns, and separate SSCV and AHT mobilizations and demobilizations, are projected to be required to fully remove the HHH platforms because the challenging oceanographic conditions offshore Point Arguello restrict heavy lift operations to a 150-day period between May and October.

Four campaigns by the SSCV and AHT would consume about 300,000 metric tons (mt) of marine diesel oil and release approximately 470,000 mt of CO2 and 11,000 mt of NOX emissions. To put these numbers into context, 470,000 mt of CO2 and 11,000 mt of NOX are:

  • the amount of CO2 emissions released by providing electrical power to 97,600 homes annually (the city of Santa Barbara has about 38,000 housing units).
  • the amount of CO2 emissions released by burning 1.1 million barrels of oil.
  • the amount of CO2 emissions released by 102,000 gasoline burning cars annually.
  • the amount of NOX emissions released by four large oil or coal-fired power plants annually.
  • the total annual NOX emissions in Santa Barbara County.

And this is only the emissions released during mobilization and demobilization of the SSCV and AHT. If full removal is required, an additional 50 days of operational time by the SSCV and AHT is estimated to be required to remove the topside and jacket of each HHH platform. This could be reduced to about 15 days per platform if the jackets are converted to artificial reefs. Only one SSCV and AHT campaign may be required if the HHH jackets are reefed, compared to the four campaigns required for the full removal scenario. This would result in a 75 percent reduction in CO2 and NOX emissions.

Background: By a 3-2 vote, the Santa Barbara County Planning Commission, acting under the direction of the Board of Supervisors (also by a 3-2 vote), passed ordinances to ban new onshore oil and gas wells and phase out old wells.

The quote:

“We keep discovering new oil and new techniques to recover it,” said Commissioner John Parke. “The only thing to stop the oil industry and the production of oil is legislation.”

Comments:

  • The first sentence is perceptive, acknowledging that resources are not really finite given the ingenuity of engineers and geologists.
  • The second sentence is disturbing. The Commissioner believes he is legally and morally entitled to terminate an industry that has been present in Santa Barbara County for >130 years. He believes the Commission can do so by a slim majority and without compensation to those whose property rights are being abrogated.
  • The 2 Commissioners voting against euthanizing the County’s oil industry represent Districts 4 and 5 (maps below) where most of the wells are located. In essence, South County Santa Barbara is terminating an industry that is important to North County.
  • Pertinent to the County’s action is a suit filed by John and Melinda Morgan, who inherited the mineral rights to two parcels in the Cat Canyon Field (District 4). They argue that a similar provision in CA Senate Bill 1137 amounts to an unconstitutional taking of their property.

I’m attaching the complete comment letters from Sable Offshore and their main antagonist, California Attorney General Bonta, in response to PHMSA’s public notice and request for comments on Sable’s special permit application.

Summary of the California AG’s assertions:

“First, PHMSA is without authority to grant such a special permit because Lines CA-324/325 are intrastate pipelines and California regulators have sole regulatory oversight over any attempt to restart these Lines and issue state waivers. Second, California has vested interests in ensuring Lines CA-324/325 operate safely and PHMSA’s proposed special permit would dilute the higher state safety standards that were imposed on Sable and therefore it is inconsistent with pipeline safety. 49 C.F.R. § 190.341(d). Third, given the fact Line CA-324 already failed and caused a catastrophic oil spill in 2015 in Santa Barbara County, even if PHMSA had authority to issue a special permit (which it does not), a more robust environmental analysis needs to be performed. Fourth, PHMSA unlawfully invokes the Endangered Species Acts’s emergency consultation procedures and has given no indication that it will consult with the National Marine Fisheries Service, in violation of the Act. Finally, Secretary Wright’s March 13, 2026, order (“DPA
Order”) does not change anything about the propriety of the Application, because the DPA Order itself is unlawful.”

The EIA has revised Gulf of America oil production slightly downward for Nov. and Dec. such that we now have an absolute dead heat between 2025 and 2019. Production for both years averaged exactly 1.898 million bbls/day.

Because of the ~6 month lag in obtaining verified OCS production data from the Office of Natural Resources Revenue (ONRR), the monthly EIA reports are based on ONRR’s more timely sales of production data. The final sales and production numbers are typically very close. For the 2019 record OCS production year, both the EIA and ONRR report identical Gulf production of 1.898 million bopd.

Meanwhile, 2026 Gulf production (chart below) is off to a strong start – 2.019 million bopd in January. This is the third highest monthly oil production in the history of Gulf operations.

Finally, California OCS oil production, which has been hobbling along at ~10,000 bopd (2nd chart) will see a massive increase of up to 500% should Santa Ynez Unit production continue.

Sable Offshore Corp. (3/30/2026) today announced that on March 29, 2026, Sable initiated oil sales. The Santa Ynez Pipeline System was filled from Las Flores Canyon to Pentland Station at a rate in excess of 50,000 barrels of oil per day.

At the Santa Ynez Unit, Platform Harmony is currently producing approximately 22,000 gross barrels of oil per day. Additionally, the United States Department of the Interior’s Bureau of Safety and Environmental Enforcement has completed its final pre-restart inspection of Platform Heritage. Sable plans to commence production restart at Platform Heritage today at an expected total rate of over 30,000 gross barrels of oil per day. We expect Platform Hondo to be online by the end of the second quarter of 2026 at a rate in excess of 10,000 barrels of oil per day.

Sable Chairman and Chief Executive Officer, Jim Flores, said “Sable is proud to announce oil sales through the Santa Ynez Pipeline System to Chevron. In doing so, we are providing American oil from American soil through an American pipeline to an American refinery for American consumers and the United States military.

A wild month in the 50 year Santa Ynez Unit saga is ending with a flourish. The wind is at Sable’s back, but storm clouds are on the horizon.

Tyler Priest, the leading historian on US offshore oil and gas operations, has informed me that his much anticipated book, “Offshore Oildom,”is now available for order from LSU Press. Tyler’s book is a fascinating account of the history of the technologically innovative and economically important, yet controversial, OCS Oil and Gas program. See the attached flyer.

Consider this recommendation by Daniel Yergin:

“Tyler Priest, a preeminent historian of energy and the environment, explores how a single well drilled off a pier near Santa Barbara in 1898 gave rise to a major American industry—offshore oil and gas. In spirited prose, Priest demonstrates how this U.S. industry was created not only by innovation, creative engineering, and complex execution; it was also the result of fierce political battles.” ~Daniel Yergin, Pulitzer Prize–winning author of The Prize: The Epic Quest for Oil, Money, and Power and The New Map: Energy, Climate, and the Clash of Nations.

You can order the book from LSU Press.

For 40 years, challenges associated with bankruptcies (or the threat thereof), a divided offshore industry, political pressure, hurricane damage, and unresolved legal issues have hindered initiatives to better protect the public from decommissioning liabilities. Nonetheless, regulators and industry were able to prevent taxpayers from incurring any decommissioning costs. Unfortunately that is no longer the case.

For the first time in history, the govt has funded decommissioning on the OCS (and bragged about it – photo below).

Federally funded decommissioning operation in the Matagorda Area of the Gulf.

BOEM’s proposed revisions to the decommissioning regulations (attached) would facilitate the transfer of aging structures to companies with limited assets, and in some cases, poor or undemonstrated safety records.

The proposal would reduce or eliminate the supplemental financial assurance requirement if a predecessor lessee has a strong credit rating. For that strategy to work, related decommissioning issues must be addressed. and clarifications and boundaries provided to ensure taxpayers are protected from decommissioning liabilities.

Predecessor liability, which is important because it helps prevent companies from assigning leases for the purpose of avoiding decommissioning obligations, was not established in the regulations until much of the OCS infrastructure was already installed. In a final rule that was effective on 8/20/1997, my office (thanks to the perseverance of Gerry Rhodes, John Mirabella, and Dennis Daugherty) codified the joint and several liability principle in 30 CFR 250.110 as follows:

(b) Lessees must plug and abandon all well bores, remove all platforms or other facilities, and clear the ocean of all obstructions to other users. This obligation:
(1) Accrues to the lessee when the well is drilled, the platform or other facility is installed, or the obstruction is created; and
(2) Is the joint and several responsibility of all lessees and owners of operating rights under the lease at the time the obligation accrues, and of each future lessee or owner of operating rights, until
the obligation is satisfied under the requirements of this part.

Prior to the that rule, the official policy of the Dept. of the Interior, as expressed in a 1988 letter from the Director of the Minerals Management Service (see excerpt pasted below), was that lease assignors would NOT be held accountable should their successors fail to fulfill their decommissioning responsibilities.

A major unanswered question regarding decommissioning obligations is thus the extent to which predecessor liability applies to leases assigned prior to the 1997 regulation. According to BOEM data, 771 remaining platforms were installed at least 10 years before the rule change, and 504 were installed at least 20 years prior. For assets transferred prior to the rule change, do the predecessors retain liability? BOEM should explain its position on this issue.

Other predecessor liability questions that need to be answered:

  • Now that the reverse chronological guidance has been scrapped, what will be the process for determining which predecessors will be held responsible?
  • If the govt doesn’t ensure that the new lessees fulfill their performance obligations (e.g. funding escrow accounts, well plugging, insurance, etc.), are predecessors still liable?
  • What if the structures were poorly maintained by the new lessees, complicating decommissioning and increasing the costs
  • Should a predecessor several transfers removed from operating the facilities still be held responsible?

Two examples of what can happen (and has happened):

Example 1: Big AAA Oil assigns a lease to Proud Production, a reputable independent. After years of operations, Proud can no longer profitably produce from the lease. Proud assigns the lease to CCC Oil & Gas, a small and highly efficient operator. After the lease is no longer profitable, even for a company with a low cost structure, CCC assigns the lease to Elmer’s E&P, a sketchy, barely solvent operating company with a poor compliance record. Elmer rather predictably neglects maintenance and declares bankruptcy after a decline in oil prices. Should Big AAA Oil, which had no say in the last 2 transfers in the assignment chain, be financially responsible for decommissioning the facilities?

Example 2: Big AAA Oil assigns a lease to DDD Development Company. Per the terms of the assignment, DDD establishes an Abandonment Escrow Account, as provided for in 30 CFR 556.904. BOEM allows DDD to withdraw funds from the account for purposes not authorized in the regulations. Should Big AAA Oil be liable for decommissioning costs after DDD is no longer solvent? (See “The troubling case of Platforms Hogan and Houchin.”)

For predecessor liability to be fairly and effectively implemented, and survive legal challenges, BOEM should:

  • Before approving lease assignments, verify that the assignors and assignees have contractually specified, to BOEM’s satisfaction, how the decommissioning of assigned assets will be funded.
  • Not approve subsequent lease assignments until the predecessor that is being held financially responsible has approved a funding agreement with the new lessees.

Another important concern is that BOEM’s proposal does not correct two prior changes that further expose the public to decommissioning liabilities:

On Monday, Sable got a boost from Judge Wilson, U.S. District Court for the Central District of California. Judge Wilson denied a request by the California Department of Parks and Recreation (and other State agencies) to enjoin Sable Offshore from restarting or continuing the operation of oil pipeline segments withing Gaviota State Park.

Sable got another boost from Chevron, which agreed to buy 20,000 bopd from Sable for its El Segundo refinery.

Not to be denied, the California Attorney General filed the attached lawsuit in the U.S. District Court for the Northern District of California. The AG argues that US Energy Secretary Chris Wright has no authority under the Defense Production Act (DPA) to excuse Sable from compliance with state and federal laws and court orders. The lawsuit alleges that the DPA Order violates the Administrative Procedure Act and infringes on California’s sovereign power under the Tenth Amendment.

The suit also alleges that the Order violates the constitutional Separation of Powers by purporting to override not only state law and a preliminary injunction issued by the Santa Barbara Superior Court, but also a judicial Consent Decree approved by the U.S. District Court for the Central District of California that expressly acknowledged and approved the State’s role in reviewing and approving any planned restart of the onshore pipelines.

The AG asks the Court (p. 33) to issue a judicial declaration that the Wright Order is unconstitutional and/or unlawful because it violates the APA and the U.S. Constitution.

Read the Court filing for full details, and stay tuned. No doubt there will be more swings in momentum going forward.

Add the unprecedented events of the last two weeks to the long and troubled history of the Santa Ynez Unit dating back to the Offshore Storage & Treatment facility days. There are no parallels in the history of the US OCS program.

To date in March:

3/3/2026: The Dept. of Justice issues an opinion asserting that, under the Defense Production Act of 1950 (DPA), an order issued by the President or his delegee would preempt California laws currently impeding Sable from resuming production and operating the associated pipeline infrastructure.

3/13/2026: Secretary of Energy Chris Wright issues an order to Sable invoking the DPA to immediately prioritize and allocate pipeline transportation services for hydrocarbons from the SYU through the Santa Ynez Pipeline System (SYPS).

3/14/2026: A letter from California Parks and Recreation demands that Sable remove all four miles of its pipeline from Gaviota State Park.

3/14/2026: Sable resumes the transportation of Santa Ynez Unit oil through the SYPS from Las Flores Canyon (LFC) to Pentland Station. Prior to resuming hydrocarbon transportation from LFC to Sable’s sales point at Pentland Station, Sable had approximately 540,000 barrels of processed crude oil in storage at LFC, representing more than the line fill volume for the SYPS between LFC and Pentland Station.

3/16/2026: Sable resumes oil production at anticipated rate of 50,000 bopd and expects first sales by April 1, 2026. Production ramp-up is anticipated to proceed with full production resumption at Platforms Harmony and Heritage this month and Platform Hondo in June 2026
