“Natural gas and LNG are fast becoming the gravitational center of the global energy system, but some energy experts said the world is only beginning to grasp the scale of what’s to come.” ~Natural Gas Intelligence

Demand and high well producibility are stimulating exploration in the high pressure, high temperature Western Haynesville (Texas) and other ultradeep onshore gas prospects. Is it time to revisit ultradeep gas on the Gulf of America shelf? See the above targets map from 2004.

20 years ago Newfield, Exxon, and McMoRan drilled pioneering ultradeep wells targeting gas-prone reservoirs below salt welds in Miocene and older formations (diagrams below). The water depths were <100 feet but well depths exceeding 30,000 feet, and high temperatures and pressures, pushed the limits of drilling technology at the time. Noteworthy wells:

  • Blackbeard West (Exxon): Spudded in early 2005 in 70 feet of water in South Timbalier Block 168. The target was gas in Miocene sands at 27,000-32,000 feet total depth. Drilling reached 30,067 feet by 2006, but was prudently suspended due to extreme pressures, temperatures (up to 600°F), and technical challenges with equipment.
  • Blackbeard West, part 2: In 2008, McMoRan re-entered the well with upgraded equipment and drilled to a record 32,997 feet below the mudline. They encountered hydrocarbon shows in multiple zones, including potential gas pay in Middle and Deep Miocene sands below 30,000 feet, validating the ultradeep concept.
  • Followup McMorRan wells:
    • Blackbeard East (2010-2011): Drilled to 33,400 feet in South Timbalier Block 144, logged potential hydrocarbons in Sparta and Vicksburg sands.
    • Davy Jones (2009-2010): South Marsh Island Block 230 in 20 feet of water; reached 29,122 feet; discovered gas in Wilcox sands, but faced flow-testing challenges.
    • Lafitte (2011): Eugene Island Block 223, found additional pay in ultradeep Miocene zones. These wells targeted gas reservoirs but encountered operational hurdles.

This program pioneered ultradeep drilling on the shelf, influencing later deepwater successes. Over the past 10 years, the deepwater industry has successfully demonstrated high pressure high temperature (HPHT) technology which could facilitate ultradeep exploration on the shelf.

Also, note that a company targeting hydrocarbons below 25,000 feet (true vertical depth subsurface) may earn an additional 3 years on their lease. (See the Notice for next week’s lease sale.) Will improved technology and demand expectations finally open the ultradeep gas frontier?

The sad state of UK North Sea production

JL Daeschler, other North Sea veterans, and those of us who once admired the UK offshore program, lament the sad plight of their oil and gas industry and the destruction of the economy in northeast Scotland.

Incomprehensibly, the UK has retained the Energy Profits Levy, which requires North Sea operators to hand over 78% of their diminished profits to the Treasury. Most have regrettably chosen to do business elsewhere. Investment in the UK North Sea is at a record low and a study from Robert Gordon University says jobs are being “quietly” lost at a rate of 1,000 a month.

The UK government is grudgingly allowing some tieback production to existing facilities, but this will do little to stem the industry’s decline. JL notes that this limited infield development is not the type of new field investment needed to grow production and sustain the service industry (rigs, boats, helicopters, equipment, etc.).

The UK Oil and Gas Authority rather smugly changed its name to the North Sea Transition Authority in 2022. Besides lower production and higher energy prices, what has the Transition Authority accomplished? As Dan Yergin correctly informs us:

“The term energy transition somehow sounds like it is a well-lubricated slide from one reality to another. In fact, it will be far more complex: Throughout history, energy transitions have been difficult, and this one is even more challenging than any previous shift.”

Related article in the WSJ: “Europe’s Green Energy Rush Slashed Emissions—and Crippled the Economy”

European politicians pitched the continent’s green transition to voters as a win-win: Citizens would benefit from green jobs and cheap, abundant solar and wind energy alongside a sharp reduction in carbon emissions. Nearly two decades on, the promise has largely proved costly for consumers and damaging for the economy.

Europe largely took an “or” strategy: It raced to replace fossil fuels with solar, wind and biomass by taxing carbon heavily, subsidizing renewables and closing scores of fossil-fuel power plants. Britain, which pioneered the use of coal for energy, last year became the first large industrialized country to shut all of its coal-fired power plants. It has also banned new offshore oil-and-gas drilling. Denmark plans to eliminate gas for home heating by 2035. Around one-fifth of Germany’s municipal utilities plan to shut down their gas networks in coming years, according to an October survey by the utilities’ trade association.”

On my favorite holiday, I’m sending best wishes to BOE readers of all persuasions. Offshore energy issues can be divisive, even among friends, and I’m grateful for the opportunity to share information and opinions.

My wife and I will be spending Thanksgiving with my daughter’s family including our 6 grandchildren, none of whom have expressed interest in being offshore safety regulators (no higher calling 😉).

Belated holiday wishes to our friends in Canada where Thanksgiving is celebrated in October, and cheers to those living where a similar fall holiday is observed.

One Big Beautiful Gulf of America

In JPMorgan’s view, the stage is set for a potential decline of as much as 50% in oil prices through the end of 2027, taking Brent crude down to the low $30s per barrel range from its current level of around $63.50.

Will bearish forecasts by JPMorgan and others temper bidding at the highly anticipated, and long awaited, Gulf lease sale to be held on 12/10/2025? Probably not for these reasons:

  • This will be the first lease sale in 2 years.
  • The terms are very attractive.
  • Given the longer term nature of deepwater development, production will not begin for years following lease issuance. Note that anticipated first production for 3 new high-pressure deepwater projects, Kaskida, Sparta, and Tiber, will be 23, 16, and 21 years after the field discovery dates.
  • To the extent that price forecasts are reliable at all (see no. 9 in the image below), the degree of uncertainty for longer term forecasts is particularly high.
  • The sale has to live up to its name Big Beautiful Gulf 1 (BBG1). 😉

“So, the safety culture is fine because we don’t report when people die.” Former Ørsted safety head, Eskild Lund Sørensen, accuses offshore wind body G+ of cherry picking data. The 2024 G+ incident data report is attached.

Member companies, which include major players such as Ørsted, Equinor, Vattenfall, RWE, and CIP, report quarterly data on accidents, near-misses, hazardous observations, and equipment damage. As is the case with most industry reporting schemes, anonymity is prioritized over transparency.

Sørensen asserts that the G+ wind industry data are incomplete: ”It shows that what is reported under the guidelines has gone down, and also that there is a cut off on what is being reported that does not include the full value chain on the industry.” He notes that a contractor to Northland Power from Canada, a member of G+, was involved in a 2024 workplace accident in Taiwan that resulted in three fatalities. (It’s also noteworthy that Equinor’s 2024 Empire Wind fatality was not included.)

Sørensen:There have been no significant improvements in the last 10 years. Safety in offshore wind is neither getting worse nor better. There are no signs of that.”

I’m speaking up because we owe people the truth. If we’re not honest about the actual safety conditions in offshore wind, we can’t change them. Misinformation about workplace safety creates a dangerous illusion that everything is “under control”, while too many people are getting hurt. But when we dare to speak about reality as it is, we create the foundation for a safer, faster, and truly sustainable energy transition,” Sørensen says.

”And then it becomes difficult to learn if you have to wait for something to go through 57 gates and down past legal,” he says. (Sound familiar?)

In the U.S., both industry and govt need to do a better job of sharing complete incident data in a timely manner.

The Gulf oil patch got a pass in 2025! 2026 is anyone’s guess.

As was the case in 2023, there were no tropical storm production shut-ins in the Gulf in 2025. Per the chart below derived from BSEE data, only 4 tropical storms caused platform shut-ins in the past 5 years. This lull followed a 6-storm year in 2020.

The Minerals Management Service Technology Assessment and Research Program began closely studying hurricane damage to offshore facilities following Hurricane Andrew in 1992. Dr. Charles Smith was a leader in these efforts. Attached is a comprehensive study report on Andrew’s effects on offshore platforms. Three background paragraphs are pasted below.

A specific description of the proposed Florida buffer in the Eastern Gulf is found in a footnote on page five of the Draft Proposed Program (DPP):

2 Includes a 100-mile coastal buffer off the coast of Florida and the area eastward of a line extending south from a point approximately 25 miles west of Tallahassee, Florida.

The 100 mile buffer seems like a reasonable proposal that minimizes the risk of coastal impacts without significantly reducing the oil and gas resource potential. However, the 125 mile buffer established in the Gulf of Mexico Security Act (2006) and the 2020 Trump withdrawal (see the comparison above) has become sacrosanct, and Gov. DeSantis and the Florida delegation oppose any change:

Unfortunately, the additional 25 miles is thought to eliminate much of the oil and gas resource potential:
