For those interested in California offshore decommissioning, attached is an excellent update presented at a 2020 forum by my former colleague John Smith.

Platform Houchin, Santa Barbara Channel

Platforms Hogan and Houchin were installed 52 and 53 years ago respectively on Lease OCS P-0166 in the Santa Barbara Channel. The lease, which had initially been issued to Phillips Petroleum, Cities Service Oil Co., and Continental Oil Co., was assigned to Signal Hill Service effective 2/19/1991. The assignment was approved despite concerns within the Minerals Management Service (MMS) about the financial strength of Signal Hill and the technical competence of Pacific Operators Offshore Inc (POOI), the affiliate that would operate the facilities.

Three decades of frustration followed for MMS, BOEM, and BSEE regulators in the Pacific Region. Per the terms of the assignment, Signal Hill was required to establish an Abandonment Escrow Account, funded from oil production revenue, with a “target balance” equal to the abandonment cost, plus 25 percent. These payments were seldom made in a timely and consistent manner.

Compliance with safety regulations was also poor. In that regard, violations data are consistent with anecdotal reports from inspectors. POOI accounted for a high percentage of the regional Incidents of Noncompliance (INCs), and Platforms Hogan and Houchin had INC/inspection ratios that were far higher than Pacific or Gulf of Mexico platform averages (see inspection data below).

A 9/20/2020 Inspector General report found significant irregularities in the use of funds from an offshore production company’s escrow account. While the IG’s summary (pasted below in its entirety) doesn’t say so, the company is assumed to be Signal Hill.

The OIG investigated allegations that an offshore oil and gas production company improperly paid operational expenses with money from an escrow account dedicated to paying expenses related to decommissioning offshore platforms in Federal waters.
We found that the company routinely used funds from its decommissioning account to pay what appeared to be various operating expenses. We also found instances where the company appeared to claim reimbursement for duplicate expenses.
Based on our findings, the company submitted credits and adjustments, totaling $1.9 million, to the decommissioning account to cover these expenses and other disbursements. In addition, we referred a number of unresolved expenses for non-decommissioning activities to the Bureau of Safety and Environmental Enforcement and the Bureau of Ocean Energy Management for resolution.
We referred this matter to the U.S. Department of Justice, which declined to pursue it.

Questions:

  1. Why haven’t BOEM, BSEE, or the OIG released the full report? The public and the offshore industry certainly have a right to know given the potential costs to the taxpayer and the reputational damage to the industry.
  2. Why was a company with such a poor payment and compliance record allowed to withdraw funds from their decommissioning account to cover operating expenses?
  3. Signal Hill owes the State $287,000 in unpaid rentals. What unpaid royalties are owed to the Federal government?
  4. BSEE (2014) estimated decommissioning costs of $74.3 million. What is the current estimate? What is the remaining balance in the escrow account?
  5. How do the escrow account irregularities affect the decommissioning obligations of prior lessees?

A recent Washington Post (WP) article, based in part on a March 2021 General Accountability Office (GAO) report, raises interesting pipeline decommissioning issues, but might benefit from some additional context, which I have attempted to provide below:

  • Decommissioning liability issues are not simply a matter of “companies trying to get out of that obligation.” Much of the complexity is associated with decades-long chains of lease ownership and the respective responsibilities of prior lessees. Pertinent questions include the following:
    • If a company sold a lease decades ago and there have since been multiple owners, to what extent is the original owner still liable for decommissioning lease facilities? (Note that guidance from the Federal government has not been entirely consistent over the decades.)
    • If current leaseholders fail to fulfill their obligations, who is next in line and why?
    • To what extent are prior lessees liable for wells and structures constructed subsequent to their ownership?
    • Knowing that decommissioning costs can vary significantly, what amounts of security should be required? How should these funds be protected or managed? Should an assigning company also collect funds to protect their interest?
    • How do inconsistent Federal policies and financial assurance requirements, and improper practices by subsequent owners, affect the liability of prior lessees? In that regard, the case of Platforms Hogan and Houchin in the Pacific OCS Region is interesting and pertinent.
  • Per the WP, “Federal regulations require the removal of offshore pipelines once they are decommissioned, but the rules are rarely enforced.” This statement is doubly incorrect.
    • 30 CFR § 250.1750 provides for decommissioning pipelines in place when the Regional Supervisor (BSEE) determines that the pipeline does not constitute a hazard (obstruction) to navigation and commercial fishing operations, unduly interfere with other uses of the OCS, or have adverse environmental effects. The consensus opinion of the regulators’ engineers and scientists has been that the safety and environmental risks associated with pipeline removal were significantly greater than those for decommissioning in place in accordance with the procedures specified in 250.1751.
    • The comment about enforcement is unfounded. BSEE and its predecessors have strictly enforced decommissioning requirements despite the challenges related to inconsistent policy direction, industry downturns, and hurricane damage. BSEE has an effective program to ensure that idle wells are plugged and platforms are removed in a timely manner. For this reason, 3315 platforms have been removed since 2001; 1933 since 2010. Only about 1800 platforms remain. This very significant loss of habitat is a concern to fishing organizations, another factor that complicates decommissioning policy.
  • In situ decommissioning of buried or trenched offshore pipelines is the standard throughout the world. The seafloor disturbance and safety risks associated with the removal of such pipelines are universally viewed as unwarranted. The pipeline decommissioning procedures followed elsewhere are similar to those described in 30 CFR 250.1751. In the Gulf of Mexico, pipelines installed in less that 200′ of water are typically buried (30 CFR 250.1003) to minimize interference with commercial fishing and other activities.
  • The decommissioning of wind turbines, which are typically more densely located and closer to shore, and their attendant power cables and substructures, will also be challenging. In their 9/16/2019 Congressional testimony, the Responsible Offshore Development Alliance expressed concern about the practice of leaving structural foundations when turbines are abandoned.

In remarks to the WP, Syed Khalil, a coastal restoration geologist for the State of Louisiana, commented that they have enough sand to meet their short term needs, but future needs were a major concern. The Gulf of Mexico Offshore Sand Management Working Group would seem to be the best mechanism for timely action and a workable, long-term action plan. The minutes of their meetings are quite instructive. Rulemaking is not a solution unless the parties want to tie their fate to both the 25 year pipeline rule rewrite (draft published in 2007, another draft coming? final?) and the contentious and similarly interminable financial assurance rule.

The Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE) has issued a Notice to Lessees and Operators (NTL) that specifies deadlines and other requirements for plugging and abandoning non-producing wells and removing platforms that no longer have utility. In my view, this regulatory action is necessary, appropriate, and consistent with authority provided in the Subpart Q (for quit :)) Decommissioning regulations. Post-hurricane experiences have demonstrated the enormous costs, operational challenges, and safety and environmental risks associated with plugging damaged wells and removing toppled platforms.
