Big Beautiful Gulf of America

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.

FPUs rule! Add Shenandoah and Salamanca to the producing list; bp commits to Tiber.

Salamanca FPU (Repsol photo)

Every deepwater platform installed since Feb. 2018, when Chevron installed its Big Foot tension leg platform (TLP), has been a Floating Production Unit (aka FPU or production semisubmersible). During that period, no new SPARs, FPSOs, or TLPs were installed.

The list (below) of these simpler, safer, greener FPUs has grown by two with the initiation of production at Shenandoah and Salamanca. Note the water depth range from 3725 to 8600 ft.

The efficiencies achieved with the simpler platform designs combined with the high pressure (>15,000 psi) technology developed over the past 2 decades is facilitatihg production from the highly prospective Paleogene (Wilcox) deepwater fans. (For those interested in learning more about the geology, see the excellent presentation by Dr. Mike Sweet, Univ. of Texas, that is embedded in this post.)

With bp’s commitment to Tiber, 3 new high-pressure projects, ala Chevron’s Anchor, are in the pipeline:

Only 10 active rigs in the Gulf of America

Posted in drilling, energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , , , , , , , , , , on September 3, 2025| Leave a Comment »

Deepwater Titan, Gulf of America

The latest Baker Hughes Rig Count Report shows only 10 rigs actively drilling in the Gulf. All are at deepwater locations – 7 in the Mississippi Canyon area, 2 in Green Canyon, and 1 in Alaminos Canyon. Per the BSEE borehole file, Shell accounts for most of the current MS Canyon wells and the Alaminous Canyon well. Beacon is also drilling in the MS Canyon, and the Green Canyon well appears to be a Chevron operation.

This current rig count, which has hovered between 9 and 12 all year, is troubling if you are concerned about long-term production. By comparison the Gulf rig count reached 22 last year and was 100+ during the 10 year period from 1994 to 2003.

Only Anadarko/Oxy, Beacon/BOE, BP, Chevron/Hess, Shell, and Talos have spudded deepwater exploratory wells in 2025 YTD. Arena and Cantium are the only shelf drillers – all development wells.

Technological advances and extensions of past discoveries have sustained Gulf production, but declines are certain over the longer term if drilling activity doesn’t increase. Oil price uncertainty is an issue, but that’s always the case. Semiannual lease sales are now legislatively required and the terms will be attractive, so those issues are off the table. Let’s see what the bidding looks like at the upcoming sale.

The decline in deepwater discoveries (BOEM data below) is particularly discouraging. Per BOEM, the last deepwater field discovery was in March 2023.

Daenerys project has an interesting mix of partners

Posted in Gulf of Mexico, Offshore Energy - General, tagged , , , , , , , , on August 21, 2025| Leave a Comment »

Talos announced successful drilling results at the Daenerys prospect (Katmai West #2) in the Gulf of America (Walker Ridge blocks 106, 107, 150, and 151).

Daenerys is a good example of the evolution of deepwater project ownership, which was once exclusively the domain of major international oil companies. Over the past 20 years, participation by independents increased gradually, followed by smaller independents and informed investment companies.

Impressively, the Daenerys partnership (table below) includes a tribe that has the same % ownership as a super-major, and a highly efficient investment company owned by a single person.

Zinc disrupts Gulf production; SPR to the rescue

Posted in Gulf of Mexico, Offshore Energy - General, tagged , , , , , , , on July 16, 2025| Leave a Comment »

Reuters and others report that zinc from a new Chevron well has contaminated oil production destined for an Exxon refinery via Shell’s Mars Pipeline System. Because contaminated crude may cause maintenance issues and reduces the quality of refined products, Exxon will not accept crude from the Mars system until the zinc issue has been resolved.

The Mars system delivers about 575,000 bopd raising concerns about supplies to Gulf Coast refineries. But fear not, DOE authorized the delivery of up to 1 million barrels of oil from the Strategic Petroleum Reserve to the Exxon’s Baton Rouge refinery.

(Ironically, yesterday’s post pointed to the importance of the SPR and questioned the decision to drastically reduce crude oil purchases. This zinc incident is likely to be minor, and Exxon will repay the SPR in kind. However, more serious regional, domestic, and international events could call for much greater SPR withdrawals.)

The above map shows Chevron platforms that connect with the Mars system at Port Fourchon.

Speculation/commentary:

  • The well/platform responsible for the zinc contamination has not been identified. Given that production is ramping up at Chevron’s Anchor facility, a new well on that platform may be the source of the zinc. Other Chevron platforms that connect to the Mars system are indicated in the diagram above.
  • Given that zinc in crude oil is rare, a well completion fluid containing zinc bromide may be the culprit.
  • Note the integration of offshore production streams, and the involvement of 3 industry super-majors. These companies are highly competitive, as evidenced by the Chevron-Exxon Stabroek dispute, but are also cooperative in producing, transporting, and refining oil and gas. However, they and other majors are restricted (rather illogically) from bidding jointly for leases.

New Orleans woman named President of Shell USA

Posted in Offshore Energy - General, Uncategorized, tagged , , , , , on May 8, 2025| Leave a Comment »

Colette Hirstius, currently Executive Vice President, Gulf of America, will take on the responsibility of President, Shell USA, in addition to her current role as Executive Vice President, Gulf of America, effective August 1, 2025.

In a city where high school ties tend to be strong and enduring, Ms. Hirstius is a graduate of St. Mary’s Dominican HS. Supreme Court Justice Amy Coney Barrett, whose father was an attorney for Shell, and my former Minerals Management Service colleague Kathy Swiler, are also St. Mary’s Dominican graduates.

Ms. Hirstius stayed in New Orleans as an undergraduate, receiving a B.S. degree in geology from Tulane.

Shell is the no. 1 oil and gas producer in the Gulf of America. In 2024, the company produced 171.7 million bbls of oil (26.2% of the GoA total) and 167.4 bcf of gas (24.4% of the GoA total).

Oil companies don’t fare well when they drift from their core businesses

Posted in CCS, energy policy, Gulf of Mexico, Offshore Energy - General, Offshore Wind, Regulation, tagged , , , , , , , , , on May 1, 2025| Leave a Comment »

BP dropped the regrettable Beyond Petroleum campaign and has now cut their renewable energy investments to focus on oil and gas production. They are doing quite well in the Gulf of America where they are the no. 2 oil and gas producer.

The leading Gulf of America oil and gas producer, Shell, has also slowed its renewable investments and is no longer participating in any US offshore wind projects.

Only Equinor (formerly Statoil), which is 2/3 Norwegian government owned, remains committed to renewable projects, much to the chagrin of some private investors. Equinor’s Empire Wind misadventure may be matched in the Pacific where their floating wind project offshore California is a long way from reality.

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.

Mobil – Montgomery Ward
Exxon – Reliance Electric
Gulf Land – Reston

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.

And how are those 199 wrongfully acquired carbon sequestration leases in the Gulf working out (graphic below)? Barring some legislative sleight of hand, those leases are worthless.

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).

2024 Safety Compliance – Chevron leads the pack

Posted in accidents, energy policy, Gulf of Mexico, Offshore Energy - General, Regulation, tagged , , , , , , , , , , , , on April 8, 2025| Leave a Comment »

This image has an empty alt attribute; its file name is image-3.png

The 2024 Gulf of America Safety Compliance Leaders are ranked below according to the number of incidents of non-compliance (INCs) per facility inspection. To be ranked, a company must:

  • operate at least 2 production platforms
  • have drilled at least 2 wells during the year
  • average <1 INC for every 3 facility inspections (0.33 INCs/facility inspection)
  • average <1 INC for every 10 inspections (0.1 INCs/inspection). Note that each facility inspection may include multiple types of inspections (e.g. production, pipeline, pollution, Coast Guard, site security, etc). In 2024, there were on average 3.4 inspections for every facility inspection.

This ranking is based solely on BSEE’s published compliance data. The absence of timely public information on safety incidents (e.g. injuries, fires, pollution, gas releases, property damage) precludes inclusion of these data.

District investigation reports are more timely and provide additional insights into safety performance. Impressively, Hess had no incidents warranting a District investigation, and was the only ranked operator with this distinction. I will comment more on the District reports in a future post

Chevron’s 2024 compliance record was among the best in the history of the US OCS oil and gas program. Was it the absolute best? Were it not for the FSI INC at a Unocal (Chevron) facility, one could unequivocally assert that it was. Further evaluation of that INC would be helpful. However, details on specific INCs are not publicly available, so the significance of that violation cannot be evaluated.

Not meeting the production facilities requirement to be ranked among the top performers, but nonetheless noteworthy, was the compliance record of BOE Exploration & Production (no relation to the BOE blog 😀). See their impressive inspection results below:

Transparency on inspections and incidents is important for a program that is dependent on public confidence. For independent observers to better evaluate industry-wide and company-specific safety performance, publication of the following information should be considered:

  • quarterly updates of the incident tables, as was once common practice
  • posting of violation summaries for inspections resulting in the issuance of one or more INCs
  • more timely publication of panel reports for more serious incidents
  • real time list of ongoing investigations including the reason for each investigation
  • status summary for civil penalties that have been proposed, including the violations and responsible parties

The Rosebank and Jackdaw saga (UK) and OCS Sale 257 (US)

Posted in energy policy, Gulf of Mexico, Offshore Energy - General, Regulation, UK, tagged , , , , , on February 12, 2025| 2 Comments »

The recent Rosebank and Jackdaw decision in the UK is similar to the OCS Sale 257 fiasco in the US. In both cases, the court ruled that downstream GHG emissions weren’t adequately considered in the environmental reviews.

In the case of the Rosebank and Jackdaw fields, Lord Ericht ruled that the environmental assessment must take into account the climate effect of downstream emissions resulting from the consumption of oil and gas produced at those fields.

The Sale 257 decision was even more extreme in that Judge Contreras ruled that BOEM failed to consider the “positive” effect that higher prices (which might result from lower US offshore production) would have in reducing worldwide demand and the associated GHG emissions.

Regardless of one’s opinion on the extent to which GHGs affect the climate, halting UK and US projects will have virtually no effect on international oil and gas demand. That demand will be satisfied by other suppliers who will reap the economic benefits.

The Sale 257 decision was overturned by legislative action.

Presumably, revised environmental assessments, will allow the previously approved UK projects, for which some facilities have already been constructed and installed, to go forward. The UK government has been considering how to calculate downstream emissions. The model will no doubt yield outcomes that are highly uncertain.

In the meantime, the UK sector of the North Sea, unlike its Norwegian counterpart, continues to flounder.

Wisdom from the Scotsman regarding UK offshore production:

“We need more of it because even the most ardent supporters of renewable energy, the most vocal proponents of net zero, quietly admit oil and, especially, gas will be needed for a couple of decades at least. That obvious truth, that inarguable necessity, is not, apparently, enough for ministers to encourage UK production, however, or temper their rhetoric around renewables.“

“Allowing our rigs and refineries to power down and relying on other countries to keep the lights on still seems a little, well, counter-intuitive. We will import oil and gas but not produce it while happily exporting contracts, skills and jobs overseas? The practical impact of Labour’s refusal to grant new exploration licences in the North Sea might remain unclear but the message it sent was absolutely crystal.“

All 5 of the simpler, safer, greener deepwater GoM platforms are now producing

Posted in energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , , , , , , , , , on January 20, 2025| Leave a Comment »

Shell Vito
BP Argos
Murphy King’s Quay
Chevron Anchor
Shell Whale

Shell’s Whale floating production unit began producing this month:

  • estimated peak production:100,000 barrels of oil equivalent per day (boe/d)
  • water depth – 8600 ft
  • 200 miles south of Houston
  • estimated recoverable resource: 480 million boe.
  • first oil only 7.5 years after discovery (includes COVID delay)
  • Vito clone: replicates 99% of the hull design and 80% of the topsides from Vito.
  • high efficiency gas turbines and compression systems
  • ~ 30% lower greenhouse gas (GHG) intensity over its life cycle than the already efficient levels being achieved at Vito. (Why the push to run electric cables from shore to North Sea platforms with ample gas production?)

All 5 of the new simpler, safer, greener floating production units are now online:

This is all good, but what is next? Will technological advances once again sustain GoM production? The short answer appears to be yes!

The efficiencies achieved with the simpler platform designs combined with the high pressure (>15,000 psi) technology developed over the past 2 decades will facilitate production from the highly prospective Paleogene (Wilcox) deepwater fans. (For those interested in learning more about the geology, see the excellent presentation by Dr. Mike Sweet, Univ. of Texas, that is embedded in this post.)

Three major high-pressure projects, ala Chevron’s Anchor, are anticipated:

The Gulf still has high production potential if properly managed with consistent lease sales.

Will Florida budge by supporting the lifting of the EGOM leasing moratorium? Here is why they should.
