John Smith shared an outstanding paper (attached) that was presented by co-author Robert Byrd at the SPE Regional Meeting in Garden Grove, CA last week.
John Smith: “My objective in writing the paper is to hopefully spur legislators to recognize the benefits of reefing and the legislative fixes required to facilitate reefing and the removal of aging infrastructure. The California Department of Fish and Wildlife Habitat Lead was very complimentary of the paper and has distributed it to the Interagency Team which is developing a California Artificial Reefing Plan.”
John adds: “They are in the process of creating a statewide artificial reef plan and you can sign up for updates and get more information. The California Artificial Reef Program (CARP) Plan won’t discuss the specifics of Rigs-to-Reefs but will be compliant with the National Fisheries Enhancement Act and National Artificial Reef Plan and meet the BSEE requirement of having an adopted state artificial reef plan. The intent is to add an addendum to the plan when resources become available to move Rigs-to-Reefs forward in California. You can check out the latest program update that further discusses the CARP Plan and Rigs-to-Reefs.”
Coast Guard photo. Thanks to Lars Herbst for bringing this incident to my attention.
In what the Coast Guard is describing as an “uncontrolled discharge” (euphemism for blowout), an 82-year-old oil well has been spewing oil, gas, and water into the coastal marshes of southern Plaquemines Parish, Louisiana, for more than a week.
In hopes of future production, prior and current owners had elected not to permanently plug the well, apparently with the State’s acquiescence.
The Coast Guard has taken over the response and has accessed the Oil Spill Liability Trust Fund.
We don’t need relaxed decommissioning and financial assurance requirements. We need a cooperative Federal, State, and industry effort to ensure that wells are plugged in a timely manner and that financial assurance is provided to protect the public interest.
Those who are concerned about minimizing the Federal government’s decommissioning risk exposure should closely monitor this process. Some companies and their political allies have sought to minimize the financial risks associated with plugging wells and removing facilities. As a result, it has been necessary to defend BOEM from unwarranted commentary about decommissioning issues and the financial assurance rule. Stay tuned!
Pending a final decision in the Guyana-Venezuela dispute, the Court ordered Venezuela to refrain from conducting elections or preparing to conduct elections in the disputed territory administered by Guyana.
Farther in the past, there were noteworthy failures (below) like Mobil’s acquisition of Montgomery Ward, Exxon’s investment in Reliance Electric, and Gulf’s real estate ventures.

Finally, don’t expect the carbon sequestration boom that some are forecasting. As wind investors have discovered, industries dependent on mandates and subsidies are risky.
Not much unites climate activists and skeptics, but they are largely aligned in their opposition to carbon sequestration (euphemism for disposal), as are fiscal conservatives. The word chutzpah comes to mind when companies seek public funds to dispose of emissions associated with the combustion of their products.
199 oil and gas leases were wrongfully acquired at Sales 257, 259, and 261 with the intent of developing these leases for carbon disposal purposes. Repsol was the sole bidder at Sale 261 for 36 nearshore Texas tracts in the Mustang Island and Matagorda Island areas (red blocks at the western end of the map above). Exxon acquired 163 nearshore Texas tracts (blue in map above) at Sales 257 (94) and 259 (69).
… and shared a mineral water toast! 😉 (Weak joke, but at least it’s original and topical!)
NOAA and TMC, a Canadian company, are working together to bypass the stifling UN deep sea minerals bureaucracy.
NOAA raises a glass: Yesterday, President Trump signed an Executive Order establishing a framework for American companies to identify and retrieve offshore critical minerals and resources. The Executive Order prioritizes U.S. leadership in seabed mapping and mineral exploration, ensuring reliable access to critical minerals like manganese, nickel, cobalt and rare earth elements.
In support of the Executive Order, NOAA is committed to an expeditious review of applications for exploration licenses and commercial recovery permits. The agency will provide the necessary resources for license and permit reviews to ensure that those reviews go forward without undue delays.
TMC is positioned to play a central role in supporting an American industrial ecosystem underpinned by deep-seabed minerals, and poised to mobilize tens of billions in private investment in the U.S. across shipbuilding, ports, mineral processing, and advanced manufacturing
The Company through its U.S. subsidiary expects to file license and permit applications under the U.S. Deep Seabed Hard Mineral Resources Act (DSHMRA) in the second quarter of 2025
China boos: “The US authorization… violates international law and harms the overall interests of the international community,” Chinese foreign ministry spokesman Guo Jiakun said on Friday.
TMC and other companies like Impossible Metals (see below) have had enough of the endless delays at the United Nations’ International Seabed Authority, which is still developing regulations. Mining companies and others have spent years gathering data and providing input.
Meanwhile in US waters:
San Jose, CA – Impossible Metals, a pioneering US-based deep-sea mining company, has submitted a request to commence a leasing process for exploration and potential mining of critical minerals in the deep sea off the coast of American Samoa. Impossible Metals is the first company to request a lease of critical minerals under the Outer Continental Shelf Lands Act of 1953, which is regulated by the U.S. Bureau of Ocean Energy Management (BOEM), part of the U.S. Department of the Interior.
Impossible Metals has developed the only autonomous underwater robot (AUV) for selective harvesting. The novel underwater robot uses advanced robotics, AI, and a buoyancy engine to hover above the seabed, accurately identifying and avoiding nodules with visible life while minimizing disruption to the habitat and native biodiversity. This method will have the lowest environmental impact and cost among land and deep-sea mining approaches, setting a new standard for responsible resource collection.
BSEE’s decision to revise downhole commingling policy by increasing the allowable pressure differential between reservoirs is sound and supported by an impressive University of Texas (UT) Petroleum Engineering study. Although the announcement hype is a bit much, this is the way regulation is supposed to work.
The main benefit of commingling (vs. sequential production) is the accelerated return on investment, which is fine as long as other risks are not introduced and ultimate oil recovery is not sacrificed. The UT study of Paleogene (Wilcox) reservoirs found that downhole commingling actually maximizes per-well oil production compared to sequential schemes. Over 30 and 50 years, commingling yields 61% and 21% more oil respectively.
The UT study analyzed 3 cases with 19 variables (Table 2 in their report). The reservoir pressure differentials were 500, 1000, and 1500 psi. Interestingly, pressure differential had essentially no impact on cumulative production in either the commingled or sequential scenarios.
Figure 13. Cumulative production over 50 years for commingled (left) and sequential (right) production scheme. The most significant variables are shown in the first four pairs of plots. The last pair of plots shows the least important parameter which is pressure difference between reservoir units.
Also note that (fig. 13):
As the upper reservoir thickness increases to 1000 ft (high case), total production increases by 41% for the commingled production scheme and 26% for the sequential production scheme.
The second most important field feature is upper reservoir facies proportion for both production schemes. A higher sand proportion in the reservoir results in higher production.
United Oil & Gas Plc (AIM: “UOG”), the oil and gas company with a high-impact exploration asset in Jamaica and a development asset in the UK, is pleased to announce that it has secured an early two-year extension to the Walton Morant licence offshore Jamaica, now valid until 31 January 2028, where it holds a 100% working interest.
The Company would like to formally acknowledge and thank the government and people of Jamaica for the continued support of oil and gas exploration in Jamaica. The extension provides UOG with the security required to advance discussions with farm-in partners and progress technical work, reinforcing the significant exploration potential of this licence.
With the extended tenure confirmed, United have re-engaged with selected parties who had previously expressed interest before the farm-out process was suspended in December 2024, as well as new interest from additional groups. At present, multiple companies are under Non-Disclosure Agreements (NDAs) and actively reviewing data as part of the farm-out process.
Comments:
The Jamaican govt not only granted a second 2 year license extension, but they did so 10 months before the deadline. Could the upcoming elections, scheduled for later this year, have been a factor in the timing of their decision?
Does the govt have that much confidence in a company that is dependent on finding a partner to fund an exploration well?
If the license had been allowed to expire, was the govt concerned about administrative or political constraints associated with re-offering the license area?
United Oil and Gas excels at promotion and isn’t shy about making bold statements about their Walton-Morant license. They have been talking for several years about strong interest from prospective partners, but no deal has been made.
United’s estimate of 7 billion barrels for the license area represents the sum of the prospective unrisked resources for each prospect. The resource estimate is dependent on oil being discovered and developed at each prospect, and is thus speculative.
Although combustion of natural gas emits 30% and 45% less CO2 than oil and coal respectively, the CO2 emissions are still significant. As a result, those who focus solely on greenhouse gases and ignore all other impacts (e.g. other air pollutants like NOx, SO2, and particulates, land use and space preemption, visual effects, and wildlife risks), want to limit the production and use of gas. However, whether or not fossil fuel consumption is significantly affecting the climate, the use for natural gas will be economically and environmentally imperative for the foreseeable future.
Not all natural gas production is equal from an environmental standpoint. Because this is an offshore energy blog, I draw your attention to the unique advantages of offshore gas production: minimal visual impact, bird friendly (rigs-to-roosts!), no risks to freshwater aquifers, and few land use issues.
Currently, most offshore gas production is in the form of oil-well gas (AKA associated or casing head gas). Offshore gas production is thus being primarily driven by oil demand, and is an added benefit from deepwater oil development.
Offshore gas-well or non-associated gas is largely the domain of independent operators producing in the shallower waters of the continental shelf. Non-associated gas has an added benefit in that there is little or no spill risk (depending on how dry the gas is). Shelf gas platforms also provide ecosystem benefits through their reef effect (rigs-to-reefs). Sustaining this non-associated gas production is therefore desirable from both energy and environmental standpoints.
