“Today’s announcement delivers on Harbour’s long-standing ambition to establish a presence in the deepwater Gulf of America. With LLOG, we found the right combination of high-quality assets and a talented team, providing a strong strategic and cultural fit with our company. The transaction positions us as a leading player in a region with well-established infrastructure, a supportive fiscal and regulatory environment and opportunities for additional growth.”
LLOG was the 6th largest Gulf of America producer of both oil and gas in 2024 with production of 27 million bbls of oil and 34 BCF of gas. LLOG was the high bidder on 11 tracts in the recent BBG1 sale.
Harbour is not currently a Gulf of America leaseholder.
Reuters had reported that Shell was in advanced talks to acquire LLOG. Apparently, either Shell lost interest or Harbour made a more attractive offer.

While the majors and large independents garner most of the attention, smaller companies are an integral part of the mosaic that is the Gulf of America petroleum province. Some focus on producing and identifying remaining reserves on the shelf; others partner in deepwater projects.
Sale participants like Arena, Cantium, Walter, W&T, Beacon, Kosmos, and Houston Energy are well established Gulf leaseholders. Red Willow has attracted attention as a successful Southern Ute energy corporation.
Which majors will be the most active bidders? BP (50 high bids), Chevron (22), and Shell (12)
Will former Gulf of Mexico stalwarts Exxon and Conoco Phillips participate for the first time in years? They did not.
How many companies will submit bids? Would like that to be a number >35. Only 30 companies participated.
How many tracts will receive bids? A number >300 would be very encouraging. Only 181 tracts received bids.
Will the total high bids exceed $400 million? No, the total was $279.4 million.
Will we see an increase in shelf interest? Shelf bidding continued to be limited (map). Renaissance, Byron, Arena, GOM Shelf LLC, Walter, W&T, Cantium, and WYOTEX Offshore submitted bids for shelf leases.
Which independents will be the most active? Woodside and Murphy are large independents, and their participation was most impressive. Murphy submitted 14 high bids totaling $27.4 million. Woodside had 8 high bids including the sale’s two highest for a total of $38.1 million, second only to BP in terms of the sum of their high bids.
Seconds matter – training, equipment maintenance, and effective leadership are critical!
Several BSEE Safety Alerts have just been released. Of particular importance to those interested in deepwater drilling is the attached alert describing two separate Emergency Disconnect Sequence (EDS) incidents.
The EDS (see the diagram above) is a critically important safety protocol that ensures that a well is sealed and the riser and rig are disconnected from the blowout preventer in the event of a well control emergency, unforeseen weather/ocean conditions, loss of power, or positioning system malfunction. Note that the Macondo blowout could have been prevented if the Deepwater Horizon crew had activated the EDS in a timely manner.
The two EDS events cited in the Safety Alert were presumably the March 28, 2025 and March 5, 2024 incidents investigated by BSEE district offices. The drillships were the Stanley Lafosse and the Deepwater Poseidon The investigation reports provide detailed information on these incidents.
Unintended riser disconnects not associated with EDS activations are a related safety and pollution concern that necessitated the issuance of a 2000 Notices to Lessees that was subsequently updated:
BOEM informs (post below) that Wednesday’s BBG1 oil and gas lease sale will be streamed live here at 10 AM ET. Given that this is the first sale in two years and the first BBG sale, some dignitaries may be in attendance.
On December 10, we will host the Big Beautiful Gulf 1 oil and gas lease sale, our first under the One Big Beautiful Bill Act.
Will the oil and gas lease sale boldly named Big Beautiful Gulf 1 (BBG1) live up to its grand name? Given the more favorable lease terms and the 2 year gap since the last sale, BBG1 should surpass the previous 3 sales (table below). Questions:
Which majors will be the most active bidders? Chevron? Shell? BP? Oxy/Anadarko?
Will former Gulf of Mexico stalwarts Exxon and Conoco Phillips participate for the first time in years? Probably not, but US super-majors should participate in the US offshore program.
How many companies will submit bids? Would like that to be a number >35.
How many tracts will receive bids? A number >300 would be very encouraging.
Will the total high bids exceed $400 million?
Will we see an increase in shelf interest?
Which independents will be the most active?
After the not-so-clever carbon disposal acquisitions in the last 3 sales, will the number of carbon disposal bids be zero? For the first time ever, the Federal government felt compelled to stipulate the obvious (see the proposed notice for OCS Sale 262) – that an Oil and Gas Lease Sale is only for oil and gas exploration and development.
See the summary data below for the last 3 Gulf lease sales. We’ll fill in the blanks next week.
Sale No.

“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.
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?
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:
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). 😉
