Platform Holly, California State waters in the Santa Barbara Channel, formerly operated by Venoco
Platform Holly sits immediately offshore from the Univ. of California at Santa Barbara, and UCSB scientists have studied the platform and surrounding ecology extensively. Multiple studies have shown that production from Holly reduced natural seepage and methane pollution from shallow formations beneath the Channel. Platform Holly was thus a “net negative” hydrocarbon polluter.
The natural seepage in the Santa Barbara Channel was important to the earliest inhabitants of the area. The Chumash used the tar for binding and sealing purposes, including caulking their canoes. Since Holly shut down in 2015 following the Refugio pipeline spill, offshore workers and supply boat crews have reported a considerable increase in gas seepage.
Earlier this month, it was reported that well plugging operations at Holly had now been completed, but decisions regarding the final decommissioning of the platform remain.
Venoco declared bankruptcy in 2015 and the State of California became the platform owner. According to the State Lands Commission, Exxon will pay the costs for decommissioning the platform. This is because Exxon acquisition Mobil operated the platform from 1993-1997 before Venoco became owner.
The most recent Holly development is that Venoco has settled its law suit with Plains, the company responsible for the 2015 Refugio pipeline spill that halted production from Holly. Terms of the settlement have not been disclosed.
Note: As an aside, I’m curious as to whether Mobil provided a decommissioning guarantee as part of the sale to Venoco or whether the State is simply holding ExxonMobil accountable as a legacy owner. If it’s the latter, why isn’t bp (bp acquisition Arco was Holly’s operator from 1966-1993) also liable? Is it a matter of Mobil being the more recent predecessor owner?
The previously discussed sale of Cox assets in 6 GoM fields to W&T was completed in January for $72 million, $16.5 million less than the proposed price. W&T, an established GoM operator, believes they can increase the pre-bankruptcy production (8300 boepd) through workovers, recompletions, and facility repairs.
The extent to which W&T is assuming decommissioning liability for the Cox assets is unclear to this observer. Decommissioning information from W&T’s SEC filing is pasted at the end of this post.
In February, Cox won court approval to sell “about a dozen oil fields to Natural Resources Worldwide LLC for about $20 million following a bankruptcy court auction.” This sale is more concerning given that the purchaser has no operating history in the GoM, and scant information about the company can be found online. Perhaps they are affiliated with Natural Resources Partners L.P., an energy investment firm which “owns mineral interests and other rights that are leased to companies engaged in the extraction of minerals,” but “does not mine, drill, or produce minerals, has no operations, and conducts business solely in an office environment.”
Per BOEM data, Cox filed requests to assign a number of leases to Natural Resources Worldwide (NRW) in May, but those requests have yet to be approved. Hopefully, BOEM is taking a hard look at these requests and their obligations following the court auction. Decommissioning liabilities should be their number one concern. (Note: NRW was just listed as the operator of the former Cox platform at EI 361, so presumably at least some of those assignments have now been approved.)
According to BOEM’s platform data base, Cox and affiliates Energy XXI and EPL still operate 243 platforms, down from 435 in June 2023. Also per the data base, the Cox companies have not removed any platforms during 2023 or 2024 YTD, so the reduction in platforms is presumably the result of the W&T transaction. Most of the remaining Cox platforms are old – 16 of their 77 major platforms were installed in the 1950s!
Meanwhile, Cox and affiliates continue to be the GoM violations leader by far with 549 incidents of non-compliance (INCs) in 2024 YTD, 45% of the GoM total for all operators. No other company has more than 100 INCs (although Whitney Oil and Gas has a disappointing 93 INCs, including 33 facility shut-ins on only 65 inspections!)

INCs are for 2024 as of 9/17/2024. A major platform has at least 6 well completions or more than 2 pieces of production equipment.
The Company may be subject to retained liabilities with respect to certain divested property interests by operation of law. Certain counterparties in past divestiture transactions or third parties in existing leases that have filed for bankruptcy protection or undergone associated reorganizations may not be able to perform required abandonment obligations. Due to operation of law, the Company may be required to assume decommissioning obligations for those interests. The Company may be held jointly and severally liable for the decommissioning of various facilities and related wells. The Company no longer owns these assets, nor are they related to current operations.
During the three months ended March 31, 2024, the Company incurred $2.6 million in costs related to these decommissioning obligations and reassessed the existing decommissioning obligations, recording an additional $5.3 million. As of March 31, 2024, the remaining loss contingency recorded related to the anticipated decommissioning obligations was $20.8 million.
Although it is reasonably possible that the Company could receive state or federal decommissioning orders in the future or be notified of defaulting third parties in existing leases, the Company cannot predict with certainty, if, how or when such orders or notices will be resolved or estimate a possible loss or range of loss that may result from such orders. However, the Company could incur judgments, enter into settlements or revise the Company’s opinion regarding the outcome of certain notices or matters, and such developments could have a material adverse effect on the Company’s results of operations in the period in which the amounts are accrued and the Company’s cash flows in the period in which the amounts are paid. To the extent that the Company does incur costs associated with these properties in future periods, the Company intends to seek contribution from other parties that owned an interest in the facilities.
I’m not typically aligned with the sponsors of the attached “Plug Offshore Wells Act,” but the call for transparency is understandable given that taxpayer funds are, for the first time, being used to decommission offshore platforms in the Matagorda Island area of the Gulf of Mexico, massive liabilities associated with the Cox bankruptcy loom, and the Hogan and Houchin saga drags on without resolution.
The bill would require an annual report on well, platform, and pipeline decommissioning including applications, deadlines, and enforcement actions. BSEE does have a good facility infrastructure page for the GoM, but much of the information called for in H.R. 9168 is not publicly available.
While exploration technology has improved significantly, the success rate for wildcat exploratory wells is still only about 30%. According to Rystad, only eight of the 27 high-impact wells drilled in 2023 resulted in commercial discoveries.
In baseball terms, the smaller independents are typically singles hitters, drilling development wells and gleaning reserves from established fields. The majors tend to be home run hitters. They swing hard and often miss, but when they hit, the rewards are great!
