On February 12, 2024, the bankruptcy court approved the sale of certain Cox Operating assets to Natural Resources Worldwide LLC (NRW), a company that had no prior offshore experience. NRW contracted with Array Petroleum to operate 154 Cox legacy platforms (per MMA data). NRW is listed as the operator of just one platform.

The bankruptcy court had previously approved the sale of Cox assets in 6 Gulf of America fields to W&T Offshore.

As noted in previous posts, the Cox legacy of non-compliance has continued under new ownership. In 2026 YTD, Array Petroleum accounted for 52% of Gulf of America Incidents of Non-Compliance (INCs) while operating only 12% of the platforms, and producing only 0.06% of the oil and 0.17% of the gas (2025 production data). Their 2026 YTD INCs/inspection ratio is 7.55 times the Gulf average and 14.6 times the Gulf average if Array inspections are excluded.

The only platform operated directly by NRW was cited for 3 INCs on 2 inspections.

Per MMA data, W&T operates 117 platforms in the Gulf. The number of platforms that were included in the acquisition of the 6 Cox fields is unknown. W&T’s INC/inspection ratio in 2023, the year before the Cox acquisition, was 0.72 (80/111), which was better than their 2026 performance (0.94), but worse than the Gulf-wide 2023 average of 0.57. So W&T’s compliance relative to other Gulf operators was about the same before and after the acquisition.

According to the borehole file, neither Array, NRW, nor W&T conducted any drilling operations in 2026 YTD.

Kudos to the MMA inspectors for their diligence in identifying INCs and issuing citations. The 2026 YTD data table is below.

The attached letter to the General Accountability Office (GAO) asserts that there were “deeply entrenched ethical issues and conflicts of interest within the former Minerals Management Service (MMS),” and implies that these issues were among the factors contributing to the tragic Macondo well blowout.

I retired from MMS shortly before the Macondo well blew out on April 20, 2020, and testified before the Senate Energy and Natural Resources Committee on May 11, 2010. My comments on MMS employee ethics still stand and are reiterated below:

I also want to express my disappointment in certain media comments directed at my former MMS colleagues. These comments have not only been ill-informed and unsubstantiated, but malicious. Without hesitation, I can tell you that MMS regulatory personnel–inspectors, engineers, scientists, and others–are 100% committed to their safety and pollution prevention mission. MMS inspectors are themselves exposed to risks every day when they fly offshore and inspect facilities. MMS personnel have repeatedly made personal sacrifices to support the regulatory mission. After Ivan, Katrina, Rita, Gustav, and Ike, MMS employees worked to restore oil and gas production essential to our economy, even when their personal lives had been disrupted by the onshore impacts of these hurricanes. These personnel work under strict ethics standards, and despite a few isolated and highly publicized incidents that occurred more than four years ago, conduct themselves with the highest degree of professionalism. While a critical review of the entire offshore regulatory regime is necessary and appropriate, unsubstantiated accusations and personal attacks are not.


The comprehensive Chief Counsel’s Report, National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling, was the only inquiry to consider whether ethical lapses were a contributing factor to the blowout. In the “Regulatory Observations” chapter, the Chief Counsel addressed ethics concerns directly (p. 261):

“In recent years various bodies have concluded that certain MMS offices and programs have violated ethical rules or guidelines. In the wake of the Deepwater Horizon disaster, some questioned whether ethical lapses played any role in causing the blowout. The Chief Counsel‘s team found no evidence of any such lapses.

This blog closely followed the Macondo blowout. I have read all of the investigation reports and many of the court documents. I also served on the defense team for Bob Kaluza, the BP Well Site Leader who was fully acquitted after being shamefully prosecuted in the wake of the blowout. My thoughts on the Macondo tragedy are summarized in a six part series.

Because of the false ethics narrative and scapegoating of MMS, experts who should have been directing the well control efforts, were pushed to the back of the bus shortly after the blowout began. Had that not been the case, I believe the top kill operation would not have been aborted in late May and the well would have been killed 48 days sooner, reducing the oil spill volume by at least 2.4 million bbls. (See the analysis by Dr. Mayank Tyagi and his colleagues at LSU.) Also, keep in mind that the USCG Incident Commander almost required BP to resume flow from the well after the capping stack successfully shut-in the well on 7/15/2010, and would have likely done so were it not for forceful input from an engineer from the former MMS.

The consolidation of BOEM and BSEE into a single bureau makes sense. As I previously commented:

This is an excellent step that many OCS program veterans have been advocating. In addition to the inefficiencies associated with overlapping and intertwined BOEM and BSEE responsibilities, the associated regulatory fragmentation is a significant safety risk factor.

The primary OCS functions including leasing, resource evaluation, economic analysis, permitting, inspection and enforcement, investigations, environmental assessment, spill response preparedness, promulgation of regulations, technology assessment, research,and decommissioning, are inextricably linked, cannot be effectively segmented, and should not be stovepiped.

Finally, with regard to the reorganization planning questions posed at the end of the attached letter, perhaps GAO should first consider the abrupt, unplanned termination of MMS. At a 2011 Ministerial Forum in Washington, an international offshore safety expert criticized that rash decision noting – “It took 87 days to stop the blowout, but only 30 days to get rid of the regulator.”

Lease sale Big Beautiful Gulf 3 (BBG3) will be held on 8/12/2026. The Final Notice of Sale is attached.

Given the rather tepid BBG1 and BBG2 results and the high sale frequency, robust bidding is not expected. Nonetheless, the BBG bidding patterns and tract evaluations have been interesting, most notably BOEM’s rejection of LLOG’s bid for Keathley Canyon 828, an expired lease block in the their Buckskin field.

Keathley Canyon 828 is not among the blocks listed for sale at BBG3. Per the Notice of Sale (p. 4), “any lease blocks whose high bids were rejected and not appealed in the immediately preceding Big Beautiful Gulf lease sale, are expected to be included as eligible for lease.” Can we therefore assume that either the KC 828 bid rejection or the prior lease expiration is being appealed?

The legislatively mandated BBG lease terms are attractive – 10 years and 12.5% royalty for deepwater blocks. A more recent legislative directive requires (wrongly in my opinion) the approval of downhole commingling requests. This accelerates the return on investments in deepwater, high pressure reservoirs. Such commingling has presumably contributed to record Gulf oil production in 2025. The longer term concern is the impact on ultimate oil and gas recovery.

Meanwhile, the Gulf rig count and well start numbers continue to disappoint. Baker Hughes (7/2/2026) lists only 4 active rigs in the deepwater Gulf – one each in the Alaminos and Mississippi Canyon areas and two in the Green Canyon Area. BSEE’s borehole file lists only 15 new deepwater exploratory well starts YTD.

Six months after the year ended, the Office of Natural Resources Revenue (ONRR) has completed their precise, to the barrel, production accounting. BOEM was correct2025 was a record OCS oil production year by a considerable amount. Total OCS production, nearly 714 million bbls, exceeded the 2019 record by 14 million bbls. EIA data still favor 2019 by a slight margin.

The 16+ million barrel difference between the 2025 ONRR and EIA OCS production totals is much larger than any such differential in recent years and warrants an explanation. Below are the 2025 OCS totals (first table) and the 2019 to 2025 Gulf totals (2nd table). As indicated in the second table, all other differentials between ONRR and EIA were <2 million bbls, and only the 2024 differential was >1 million bbls.

Gulf of America lease map: 199 oil and gas leases were wrongfully acquired for carbon disposal purposes. At Sale 261, Repsol acquired 36 nearshore Texas tracts in the Mustang Island and Matagorda Island areas (red blocks at the western end of the map above). Exxon had acquired 163 nearshore Texas tracts (blue in map above) at Sales 257 (94) and 259 (69).

As expected, the carbon disposal era in Federal offshore waters is ending before it began, and rightfully so.

Energy Intelligence is reporting that Exxon is relinquishing “more than 160 leases” in nearshore Federal waters off Texas. The actual number of oil and gas leases that the company improperly acquired for carbon disposal purposes is 163 (map above).

The reason being cited for the lease relinquishments is that the Dept. of the Interior has shelved regulations for carbon disposal on the OCS. Kudos to the DOI officials responsible for that decision. Carbon disposal has the support of no one except the companies that hope to profit from it. Further, there is no scenario under which Interior could have allowed these wrongfully acquired oil and gas leases to be converted to carbon disposal leases.

Now that these carbon disposal leases are being relinquished, it would be nice to see Exxon start acquiring OCS oil and gas leases for their intended purposes. Exxon and Mobil are historic Gulf operators who were once important contributors to the success of the OCS program.

Per the preliminary EIA data for April, Gulf of America OCS facilities produced an average of 2.107 million bopd in April. This surpasses the previous record of 2.060 million bopd set in January.

Meanwhile, the Sable bump is now evident in the EIA’s Pacific OCS production data with a ~50% March-April increase from January-February. A bigger increase should be apparent when the May numbers are posted. How will Sable fare in the upcoming court battles?

Part 1

Gulf of America flaring and venting data for 2019-2025 are summarized in the attached table. The preferred performance indicators are the percentages of produced gas that are flared and vented both for oil-well gas (OWG, also known as associated or casinghead gas) and gas-well gas (GWG or non-associated gas).

The flaring and venting table was compiled using monthly data submitted to the Office of Natural Resources Revenue (ONRR). This is the best data source because reporting is mandatory and strictly enforced, and flaring and venting are accounted for separately. All volumes are in millions of cubic feet (MMCF).

The venting and flaring volumes are segmented for both OWG and GWG production. Venting produced gas (mostly methane) is a more significant environmental concern from both air quality and greenhouse gas (GHG) perspectives.

Observations and Comments:

  • The total volume of gas flared and vented in 2025 was 9.7 bcf (chart 1). 80% of that volume was flared, leaving 20% vented. OWG flaring (chart 5) reached a new high of 7.785 bcf in 2025, a near record oil production year for the Gulf.
  • Total venting and flaring in 2025 increased by 819 million cubic feet vs. 2024. However, the 7-year trend line remains favorable (chart 1).
  • Thinking that 2019, a record year for total flaring and venting, may have biased the trend line, I extended the chart back to 2015, the first year for which I have ONRR data. As you can see in chart 2, the overall trend is still favorable.
  • The % of produced gas that was flared or vented remains persistently above the historical 1.0% target (chart 3). Flared/vented volumes were below 1% of production prior to 2018.
  • The higher flaring/venting % may be because most gas production is now from oil wells, which typically have higher flaring rates associated with processing upsets.
  • The flaring and venting gap between GWG and OWG has narrowed, largely because of an increase in GWG flaring/venting. The combined rate for GWG more than doubled over the 7 year period, rising to 0.81% vs. 1.34% for OWG. (chart 3)
  • Total venting rose to 1.7 bcf in 2025, the highest venting volume in 3 years.
  • The % of GWG being vented doubled over the past 5 years to over 0.50% (chart 4). The growth in venting warrants further investigation.
  • The % of OWG vented increased slightly to 0.20%. Further reduction in OWG venting had been expected given that OWG production is increasingly from deepwater facilities with modern flaring systems.
  • A 2020 Univ. of Michigan study found “Large, older facilities situated in shallow waters tended to produce episodic, disproportionally high spikes of methane emissions. These facilities, which have more than seven platforms apiece, contribute to nearly 40% of emissions, yet consist of less than 1% of total platforms.” 
  • Platform specific data would be helpful in further assessing flaring/venting sources and trends.

After 41 years of offshore safety leadership, Mike Saucier, an outstanding engineer and manager, is retiring from the Bureau of Safety and Environmental Enforcement (BSEE).

Like many of the offshore program’s stalwarts, Mike earned a petroleum engineering degree from the Louisiana State University (LSU). In 1984, he began his Federal career in the Houma District Office of BSEE’s predecessor, the Minerals Management Service (MMS), where he was mentored by the great John Borne.

Mike has held many important engineering and supervisory positions including Drilling Engineer and District Manager in the highly regarded Houma District Office, Regional Supervisor for Field Operations, Regional Supervisor for District Field Operations, Acting Deputy Regional Director for District Operations, and Senior Technical Advisor for the Office of the Director. When the New Orleans District Manager retired during a hiring moratorium, Mike stepped up and assumed those duties as well.

Mike impressed his colleagues with his commitment to safety achievement, the essential core element of the offshore program. His diligence, and his firm, fair, and consistent enforcement of the safety and pollution prevention regulations, earned him respect throughout the offshore industry.

Mike is an avid outdoorsman who enjoys hunting and fishing, and has 4 grandsons to mentor in those skills. Note the impressive achievements cited in the Order of the Alligator certificate (below) 😉. The Order of the Alligator recognition is most fitting given Mike’s alligator hunting expertise, which greatly impressed those of us who were unfamiliar with such exploits!

In recognition of Mike’s outstanding career, the Board of Directors of the former Minerals Management Service (fMMS) has unanimously voted to induct Mike into the fMMS Hall of Fame! Mike receives (is sentenced to? 😉) lifetime membership in the fMMS and a registered copy of the offshore world’s prized masterpiece, the painting Rig at Sunset 😉. (image and short explanation below).

Congratulations to Mike! You made a difference!

“Rig at Sunset” was painted 50 years ago by a US Geological Survey (USGS) employee who chose to remain anonymous. Initially, the masterpiece was presented to USGS (later MMS) engineers and scientists who had made important contributions to the offshore oil and gas program. Understandably, the intended recipients were so humbled by the magnificence of the painting that they could not accept it. As the painting grew in value and international prominence, framed copies were presented to outstanding retirees and the original painting was kept at a secure, undisclosed location.

The Buckskin field (LLOG) is located in Keathley Canyon blocks 785, 828, 829, 830, 871, and 872 in 6,800 ft (2,073 m) of water. The KC 828 lease expired last year and LLOG’s bid for that block at the BBG2 sale was rejected.

BOEM’s Decision Information Matrix for Sale BBG2 is attached. As previously noted, 2 of the 25 high bids were rejected: Keathley Canyon Block 828 ($1,101,202) and Atwater Valley Block 63 ($650,018).

The rejected bids were significantly below both BOEM’s Mean of the Range-of-Value and Lower Bound Confidence Interval for these single bid tracts (table below).

Block No.Companyno. of bidsbidMROVLBCI
AT 63LLOG1$650,018$2,400,000$1,800,000
KC 828LLOG1$1,101,202$24,000,000$23,000,000
MROV=Mean of the Range-of-Value; LBCI=Lower Bound Confidence Interval

In the case of Keathley Canyon 828, BOEM’s valuation is more than 20 times the high bid. BOEM valued this block far higher than any other block in the sale.

KC 828 had been previously leased and that lease expired on 9/3/2025. The lease block was part of LLOG’s Buckskin field. Apparently, the lease expired due to inactivity given that the last well reached total depth more than a year prior to the expiration date. LLOG wanted the lease back. BOEM’s rejection sends a message that the price went up (by a lot 😉).

Finally, why didn’t any other company bid on KC 828, a block that has been publicly reported as being part of the Buckskin field?

My colleague Keith Meekins shared an informative AAPG article about the importance of Miocene reservoirs in offshore oil and gas production worldwide.

“The Miocene delivered a significant amount of sand with excellent reservoir characteristics around the world,” noted Erik Scott, exploration geologist and consulting geologist/sedimentologist.

“Generally, hydrocarbons are coming from deeper, older rock – the Cretaceous, the Jurassic. By the time these source rocks get to the (hydrocarbon) generation window, the Miocene reservoirs are in place,” Scott said.

Generally, the Miocene deposits are surrounded by fine-grained muds that produced sealing potential,” he noted.

More:

  • Miocene reservoirs account for more than 40 percent of established hydrocarbon reserves in the deepwater Gulf. The Bureau of Ocean Energy Management identifies more than 9 billion barrels of undiscovered, technically recoverable Miocene resources.
  • Recently, Eni found a giant Miocene natural gas accumulation in the Kutei Basin offshore Indonesia with an estimated 5 trillion cubic feet of gas and 300 million barrels of condensate in place.
  • Azule Energy, equally owned by Eni and BP, made a recent Miocene oil discovery with an estimated 500 million barrels of crude offshore Angola.

Keith points to RTM (reverse-time migration) as an important factor in helping to unlock Miocene resources. RTM produces dramatically improved images below salt bodies and in areas of complex overburden. Per AAPG, Talos Energy used reprocessed RTM seismic to identify a bypassed Miocene fault-block closure in the Green Canyon Area of the Gulf. This structure had previously been invisible.
