Robert “Bobby” Nelson, a beloved father and husband, and a highly respected engineer, died suddenly last Saturday.
Jason Mathews, a Supervisory Petroleum Engineer with the Bureau of Safety and Environmental Enforcement, had this to say about his admired colleague:
“A legacy is not just what you leave for others; it’s the impact of your presence, the influence of your actions, and the memories you create.
Bobby was an exceptional engineer, father, husband and friend who had a lasting impact on many of us. In fact, I would argue Bobby was one of the most impactful engineers in my tenure on developing and transforming younger engineers on how to think critically on complex offshore systems and processes.
Bobby’s legacy in my industry will push on for many years, and we are forever grateful for the time we had with him.”
More from his colleagues:
Bobby dedicated much of his professional life to BSEE, where he served as a Technical Advisor since January 2020, and for the previous seven years as Well Operations Section Chief and Drilling Engineer in the Houma District.
His expertise in well control, drilling engineering, and offshore regulatory compliance was invaluable. He contributed significantly as a subject matter expert and assistant content writer for the BSEE Well Control Rule Revision Team, helping shape post-Deepwater Horizon reforms, and provided technical insights on critical projects ranging from tropical cyclone risk assessments for floating rigs to hydrate pressure coring expeditions and incident investigations.
Bobby’s commitment to safety and environmental stewardship on the Gulf of America’s Outer Continental Shelf left a lasting impact on his colleagues and the industry.
He is survived by his loving wife, Amber, whom he met at BSEE, and their young daughter. In this time of grief, please keep Bobby’s family in your thoughts and prayers.
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.
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: 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
The primary purpose of the independent investigation is to prevent recurrences at this or other projects in the US and worldwide. Available data suggest that blade failures are far too common.
(Bloomberg) — The Trump administration on Friday took action to clear the way for oil production off the California coast in a bid to ease the global fuel pressures created by the war with Iran.
The announcement by Energy Secretary Chris Wright follows an executive order signed by President Donald Trump on Friday and directs Sable Offshore Corp., a Houston-based company, to begin restoring operations for the Santa Ynez Unit and Santa Ynez Pipeline System in California.
Sen. Mike Lee has introduced legislation to repeal the Jones Act, which is drawing additional scrutiny for the increased cost of transporting US oil production and LNG to US ports.
Because facilities on the Outer Continental Shelf are US ports under the Jones Act, the Act has been problematic for both the offshore oil and wind industries. The attached Customs and Border Patrol document delves into the nuances of Jones Act compliance for lifting operations (p.14-15) and “points” on the OCS (p.17).
EXAMPLE: CBP interprets the OCSLA to extend the Jones Act to artificial islands and similar structures, as well as to mobile oil drilling rigs, drilling platforms, and other devices attached to the seabed of the OCS for the purpose of resource extraction and/or exploration operations. Such objects located on the OCS are considered points or places in the United States for purposes of the Jones Act. Similarly, floating warehouse vessels, when anchored on the OCS to supply drilling rigs on the OCS, are also coastwise points.
Check out this complex CBP ruling on the transportation of well fluids from one location in a subsea well cluster to another. See if you understand and agree with their conclusion (below).
The transportation of fluids as described in the FACTS section above, by a dynamically-positioned, foreign-flagged drill ship between wells located within an IF (integrated facility), which subsequently, transships the fluids to a coastwise qualified barge for transportation to a coastwise point, violates 46 U.S.C. § 55102.
On a related matter, it’s still unclear to me whether the attachment of the lower marine riser package to a subsea wellhead makes a floating, dynamically positioned drillship a US port under the Jones Act.

On February 27, 2026, we lost a long-time pillar of the OCS safety program, the foremost authority on California offshore oil and gas operations, and a wonderful friend and colleague.
Glenn served as a helicopter door gunner during the Vietnam War, an extremely hazardous assignment. According to historical accounts, the average life expectancy of a door gunner was two weeks. Think about that! (See the door gunner video embedded below.)
Glenn discussed his Vietnam experience with Minerals Management Service (MMS) colleague Andrew Konczvald:
“Glenn told me about encounters when the bullets were hitting the bottom of his Huey helicopter, and he was sitting on his personal armored jacket as the only protection against the bullets! He told me how he prayed every night and miraculously escaped wounds and returned home safely.”
Thankfully, Glenn survived and returned to earn a Petroleum Engineering degree from the Univ. of Southern California. He was a proud USC Trojan.
Glenn had an outstanding career in our Pacific Region office, starting in the early days when the OCS regulatory program was part of the US Geological Survey. He assessed and monitored drilling and production operations in the region, which once produced 120,000 bopd from 23 platforms, and had up to 9 mobile drilling units operating concurrently. Floating drilling operations were pioneered offshore California with the CUSS 1, and production was extended to 1200 feet of water at Platform Harmony.
Glenn had an encyclopedic knowledge of the California offshore sector, and was an expert on the history of the applicable regulations, orders, and standards. We had countless discussions about topics like OCS Order No. 2 (Drilling) and the evolution of API RP 14C (Production Safety Systems).
Glenn served on numerous MMS teams that evaluated the latest technical innovations of the offshore industry, established research priorities, and assessed safety and environmental performance. He was an authority on drilling safety and was called on to evaluate and accredit well control training programs.
Glenn respected everyone, and everyone admired and respected him. He was a man of faith, but didn’t impose his beliefs on others. Fittingly, his favorite Bible passage was John 11:25-26: Jesus tells Martha, “I am the resurrection and the life. The one who believes in me will live, even though they die; and whoever lives by believing in me will never die.”
RIP Glenn, you continue to inspire your friends, and your important contributions to society live on. We love you man!
Attached is an opinion prepared by the Assistant Attorney General, Office of Legal Counsel, for the General Counsel, Dept. of Energy. This opinion may boost prospects for Santa Ynez Unit (SYU) production, either by Sable Offshore or a successor.
A few key excerpts from the DOJ opinion (emphasis added):
p. 1: You have asked whether an order issued under the Defense Production Act of 1950 (“DPA” or “Act”), Pub. L. No. 81-774, 64 Stat. 798 (codified as amended at 50 U.S.C. § 4501 et seq.), to Sable by the President or his delegee would preempt the California laws currently impeding Sable from resuming production and operating the associated pipeline infrastructure. We conclude that it would.
p. 6: As the Supreme Court has explained, executive orders “may create rights protected against inconsistent state laws through the Supremacy Clause,” especially when such orders are issued pursuant to “congressional authorization.”
p. 20: State law, we have been advised, is not currently the only impediment to Sable’s ability to resume production and transportation of oil. A consent decree entered in United States v. Plains All American Pipeline L.P., No. 20-cv-02415 (C.D. Cal. Oct. 14, 2020), Dkt. 33 (“Consent Decree”), “currently vests authority over resumption of transportation through the onshore portions of the Santa Ynez Pipeline System with the California Office of the State Fire Marshal.” Sable Letter at 9. We have been advised that, in addition to the United States and various State of California entities, Sable is a party to the Consent decree as a result of an acquisition. You have asked whether an executive order under the DPA would displace these provisions of the Consent Decree, even though there are both federal- and state-law claims at issue in that case. For three reasons, we think it would.
