“The Bureau of Ocean Energy Management’s analysis reveals an additional 1.30 billion barrels of oil equivalent since 2021, bringing the total reserve estimate to 7.04 billion barrels of oil equivalent. This includes 5.77 billion barrels of oil and 7.15 trillion cubic feet of natural gas—a 22.6% increase in remaining recoverable reserves.”

Oil and gas reserves and cumulative production at end of year, 1975-2023, Gulf of America, Outer Continental Shelf and Slope. “Oil” includes crude oil and condensate; “gas” includes associated and non-associated gas. Reserves estimated as of December 31 each year.

This increase in reserves will not please those responsible for the current 5 Year Oil and Gas Leasing Plan. They told us that we don’t need more OCS lease sales and that our biggest concern is producing too much oil and gas for too long!

Page 6 of the Leasing Plan:

The long-term nature of OCS oil and gas development, such that production on a lease may not begin for a decade or more after lease issuance and can continue for decades, makes consideration of net-zero pathways relevant to the Secretary’s determinations on how the National OCS Program best meets the Nation’s energy needs.

Energy experts like Dan Yergin and Vicki Hollub have a much different view. Per Hollub:

Crude reserves are being found and developed at a much slower pace than they’ve been in the past. Specifically, she said the world has only newly identified less than half the amount of crude it’s consumed over the course of the past 10 years. Given the current trends, this means demand will exceed supply before the end of 2025.

A bit off-topic, but Jeff Walker, a former colleague and the MMS Regional Supervisor in Alaska, had the best quip about reserve numbers. In explaining an operator’s revised reserve numbers for a producing unit which had leases with different royalty rates, Jeff noted that “oil always migrates to the lower royalty leases.”😉

China National Offshore Oil Corp. (CNOOC) has surrendered its 21% interest in the Appomattox (Mississippi Canyon 391, 392, and 393) project and its 25% stake in Stampede (Green Canyon 468, 511, and 512). Those ownership positions were acquired in CNOOC’s takeover of Calgary-based Nexen in 2013.

CNOOC had been quite positive about the prospects for Appomattox and Stampede, which are producing at higher than expected rates. However, because of sanctions concerns, an exit from operations in the US, Canada, and the UK had been under consideration for at least 2 years.

CNOOC’s shares of Appomattox and Stampede were acquired by INEOS Energy, a UK company.

The transaction is also discussed in CNOOC’s 2024 Annual Report (p.19).

BSEE incident investigations are another window into OCS safety performance.

Panel reports are published for the most significant OCS incidents (e.g. fatalities, serious injuries, significant pollution). Unfortunately, these reports have been unacceptably delayed in recent years. Status reports are not provided leaving the public in the dark as to what is being investigated and why.

The more common investigations, conducted by BSEE’s district offices, are timely and informative. The Districts typically investigate lost time (>72 hours) injuries, crane and lifting equipment incidents, small fires, pollution events, property damage > $25k, gas releases, and other incidents requiring workers to muster for possible evacuation.

The number of District investigations in 2024 declined significantly to 31, one-third fewer than the average of 46.25 for the past 4 years.

Violations were not identified for 2/3 of the incidents.

A complete list of the 2024 District investigations follows. Hyperlinks are provided for those who want to review the reports.

The announcement was during an interview this morning (4/4/2025) with Lawrence Jones on Fox News, and is consistent with expectations and the current 5 year leasing plan.

Sustaining or preferably increasing production rates will be dependent on a reliable schedule of lease offerings and a consistent regulatory regime based on best safety management principles and continuous improvement in technology, practices, and culture. Poorly considered operating restrictions imposed by activist judges are a major risk to both safety and production.

OCS Lease Sale 259 was mandated by Congress, and was held on March 29, 2023, two days before the deadline established in the Inflation Reduction Act. Ah, but compliance with environmental law, which is of course subject to interpretation, was still required.

So the formula for eNGOs in such cases is to sue on NEPA grounds in a friendly Federal court. In the case of Sale 259, the plaintiffs asserted that BOEM’s climate change and Rice’s whale analyses were inadequate.

With regard to climate change, the reality is that incremental Gulf of America production will have virtually no effect on petroleum consumption and global GHG emissions. Increased GoA production will actually have a slight positive effect on worldwide GHG emissions given the relatively lower carbon intensity for deepwater Gulf production.

With regard to the Rice’s whale, Darren Ireland’s analysis is compelling:

Based on the limited data available on the use and occurrence of Rice’s whale in the central and northwestern GOMx (one acoustic study (Soldevilla et al. 2022b), one confirmed sighting (NMFS 2018a) and a few unconfirmed sightings (Rosel et al. 2021)), there is insufficient scientific evidence to determine that essential features for Rice’s whale conservation are indeed present in the central and northwestern GOMx. In fact, data on the life-history requirements of Rice’s whale even in the core habitat are still lacking and need further investigation.“

Unsurprisingly, Judge Amit P. Mehta of the US District Court for the District of Columbia, has ruled that BOEM’s environmental assessments on climate change and the Rice’s whale were deficient, and has ordered the parties and intervenors to jointly submit a proposed briefing schedule by April 3, 2025. “The court will also order additional briefing on remedy” (e.g. onerous operating restrictions).

In case you haven’t suffered enough, the judge’s full opinion is attached.

In light of the recent NASA/SpaceX advances in rocketry, a manned mission to Mars seems inevitable, perhaps within the next 5 years. See the SpaceX Mars landing video below.

While the space program generates more media buzz given the sci-fi appeal, the achievements of the offshore oil and gas industry are similarly impressive. The Gulf of America has its own Mars, a massive deepwater project that has been ongoing and expanding for 30 years, and may ultimately produce more than 1 billion barrels of oil equivalent (boe).

Like a mission to Mars, the successful development of deepwater oil and gas resources is a technical marvel that requires:

  • Identifying prospects deep beneath the seafloor using advanced subsurface imaging capabilities.
  • Drilling exploratory wells from floating rigs, using advanced stationkeeping systems that maintain a precise location on the water surface.
  • Drilling deep beneath the seafloor while transmitting real-time geologic, temperature, and pressure data to the rig and distant onshore locations.
  • Ensuring well integrity by installing and cementing multiple strings of protective casing.
  • Processing production at buoyant surface facilities designed to withstand worst case storm conditions.
  • Connecting clusters of subsea wells to a host surface facility that may be many miles away.
  • Increasing ultimate recovery with reservoir engineering studies and advanced well completion practices.

Life on the planet Mars will be dependent on technology developed for the offshore Mars and other deepwater projects.

Historically, falls are the most common cause of offshore injuries and fatalities, and hazardous grating is a leading contributing factor to these incidents.

BSEE’s risk-based inspection and safety alert programs have effectively drawn attention to grating risks. Attached is a recent alert describing a grating incident that could have been fatal.

A worker installing a pump in a skid above unsafe grating was kneeling on scaffolding boards. The tip of his boot was on the corroded grating when it suddenly gave way. The worker was able to grab a nearby section of piping to support himself. The 36″ x 36″ piece of grating collapsed and fell into the water.

Actually, the latest data are for December 2024, so that was before the name change. It’s a nice story nonetheless, very patriotic.😉

Most likely, the jump in production is related to increased output from the new deepwater facilities we have been following.
