Perdido: One Big Beautiful Platform 😀

The differences between the House and Senate versions of the Big Beautiful Bill are summarized in the table below. (See the previous post on the House version.)

The Senate bill includes royalty and lease terms that favor deepwater lessees, but excludes the provisions in the House bill that streamline the leasing process and minimize litigation risks. At least some of those House provisions were rejected by the Senate Parliamentarian.

The House will vote on the version that passes the Senate. So the Senate version is more likely to be enacted.

HouseSenateComment
royalty: 12.5% to 18.75%royalty: 12.5% to 16 2/3%Lowering the royalty cap to 1/6 (16 2/3%) unduly limits the Secretary’s discretion and may reduce revenues without significantly increasing production.
2 GOA sales/yr over next 15 yrs.same as HouseWould have liked the opportunity for consideration of very limited Atlantic leasing or stratigraphic test drilling, but that is not politically feasible at this time.
use Sale 254 form and stips 4-10, may update stips 1-3sale 254 lease form and stips 4-9, may update stips 1-3 and 10 The minor difference favors the Senate version. Stip 10 pertains to restrictions due to Rights-of-Use and Easement for Floating Production Facilities, and needs to be updated with each sale
mandates 10 year lease term for water depths >800 mAlthough a 10 year term for deepwater leases is generally prudent, the Secretary should be able to choose a shorter term if concerns about timely exploration and diligent development arise (more likely given the increase in leases that could be issued as a result of the 2 sales/yr mandate).
requires approval of subsurface commingling unless there is “conclusive evidence” of safety or ultimate recovery issuesAlthough BSEE’s policy change on downhole commingling was warranted, the legislative change removes essentially all discretion by mandating approval unless there is “conclusive evidence” to the contrary. Conclusive evidence is dependent on production history, at which point it may be too late.
Adherence with the Biological Opinion shall satisfy the Secretary’s obligations under the Endangered Species Act of 1973 and the Marine Mammal Protection Act of 1972This provision reduces govt/lessee litigation risks
Previous EIS’s for the Gulf of Mexico shall satisfy the Secretary’s NEPA obligation.Rejected by the Senate Parliamentarian.
Consistency determinations prepared by BOEM for Lease Sale 261 for the States of Texas, Louisiana, Mississippi, Alabama, and Florida will satisfy the Secretary’s CZMA obligations.

The States or Parliamentarian may not have been comfortable with this provision which simplifies plan approval processes.
The Secretary may waive any requirement under the Outer Continental Shelf Lands Act that the Secretary determines would delay issuance of a lease.Rejected by the Senate Parliamentarian?
A lease must be issued to the highest responsible qualified bidder not later than 90 days after the sale date.Rejected by the Senate Parliamentarian.
A Governor may nominate for leasing under a lease sale held under this section an area of the OCS that is adjacent to the waters of the StateNever understood the need for this provision.
G&G surveys must be approved within 30 days after a complete application is received.Not feasible in some cases given endangered species concerns.
A lease awarded under Lease Sale 259 or Lease Sale 261 shall not be set aside, vacated, enjoined, suspended, or cancelled except in accordance with section 5 the Outer Continental Shelf Lands Act (43 U.S.C. 1334). Also, new terms or conditions may not be added to these leases.Reduces litigation risks.
Any action to approve, require modification of, or disapprove any exploration plan, development and production plan, bidding procedure, lease sale, lease issuance, or permit or authorization related to oil and gas exploration, development, or production, or any inaction resulting in the failure to hold a lease sale shall be subject to judicial review only in a United States court of appeals for a circuit in which an affected State is located.This provision significantly reduces litigation risks. Rejected by Parliamentarian?
6+ Cook Inlet sales over next 10 yrs.6+ Cook Inlet sales over the next 7 years

Today’s Supreme Court decision limits the power of federal district judges to issue universal injunctions. I wonder if this decision restricts courts in DC and Maryland from ruling on oil and gas operations in the Gulf of America? Perhaps not, because those decisions are linked to Federal agencies in the DC area even though the activity is in the Gulf.

Minimizing flaring and venting is important from both environmental and resource conservation standpoints. Flaring and venting volumes are also good indicators of how well production systems are designed, managed, and maintained.

The best 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).

Updated flaring and venting volumes for the Gulf of America have been 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.

In assessing performance trends, it’s important to segment venting and flaring volumes 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.

Flaring and venting data for 2019-2024 are summarized in the table below. All volumes are in millions of cubic feet (MMCF).

Notes and comments:

  • The more disappointing 2024 numbers are entered in red. The blue numbers, all related to OWG venting, are encouraging.
  • The % of all produced gas that was flared or vented in 2024 (1.3%) was the highest in the past 10 years (see the chart below the table). Until 2018, annual flaring/venting rates of <1% of production were commonly achieved. This should be the target going forward.
  • OWG flared increased significantly from 2023 levels, both in terms of the volume (7.26 billion cu ft) and the % of OWG produced (1.22%).
  • Production curtailments and restarts related to Tropical Storms Francine and Helene may have contributed significantly to the 2024 flaring increase. ONRR’s monthly reports show a near doubling of the average monthly flaring volume in Sept., when Francine and Helene shut-in 42% and 29% of oil production respectively. However, even if the Sept. flaring surge is normalized to the monthly average for the other 11 months, the total 2024 flaring still exceeds the 2023 volume by 361 MMCF.
  • The % of GWG vented in 2024 was the highest in the 6 year period and double the 2019, 2020, 2021 rates. Inefficiencies associated with the dramatic decline in GWG production, down 41.5% from 2023, may be a contributing factor.
  • The continued decline in OWG venting to only 0.16% in 2024 is encouraging. The decline should be sustainable given that most OWG is now produced at modern deepwater platforms equipped with efficient flare stacks.
  • Given the significance of these data, from safety, conservation, and environmental perspectives, a more comprehensive analysis by the offshore industry and regulators should be a priority.

As the chart indicates, the % of flared or vented Gulf of America gas production increased over the past 10 years. This trend is presumably due, at least in part, to the sharp increase in the % of gas production from oil wells (associated gas), which have a higher flaring rate. In 2024, 87% of Gulf gas production was from oil wells.

Flaring/venting summary tables and comments, updated through 2024, will be posted later in the week.

The Safety Alert is attached. Per BSEE, the fires resulted from an accumulation of gas caused by improperly installed or disconnected exhaust vent piping on gas starters.

Incident 1: Two workers sustained burns to the hands, arms, and face. BSEE investigators discovered that the engine’s air intake hose was disconnected, which may have allowed gas-enriched air to be drawn into the carburetor causing the backfire.

Incident 2: While attempting to start the gas engine of a pipeline pump, the lead mechanic sprayed ether into the engine’s carburetor. The exhaust vent piping for the starter had not been installed. The combination of the gas-rich atmosphere and ether caused the engine to backfire and ignited the
accumulated gas. The lead mechanic, sustained burns to his face, arms, and hands.

The Alert includes important recommendations for proper venting, mechanical integrity awareness training, maintenance, and the use of gas detectors and a temporary fire watch during engine startup.

This week Total announced the acquisition of a 25% working interest in 40 Chevron leases in the Gulf of America. Total already owned interest in Chevron’s producing Ballymore (40%), Anchor (37.14%), Jack (25%), and Tahiti (17%) fields. Ironically, Federal regulations prohibited Total from jointly bidding with Chevron for any of those leases at the time of the sales. How does that make sense?

Restrictions limiting joint bidding by major oil companies date back to the Energy Policy and Conservation Act of 1975. Although these restrictions were intended to increase competition and revenues, OCS program economists have asserted, and studies have shown, that the ban results in fewer bids per tract and lower bonuses to the government.

Total did not submit a single bid in any of the past 4 Gulf of America lease sales. Perhaps they prefer to acquire interest in blocks previously leased to companies like Chevron. That is a reasonable acquisition strategy. However, farm-in acquisitions yield no bonus dollars to the Federal government. Wouldn’t it have been in the government’s best interest if some of those acquisition dollars were spent at lease sales where the bonus bids go to the US Treasury? It’s long past time to remove the joint bidding restrictions!

As explained in the attached Safety Alert, BSEE’s risk-based inspection program has identified deficiencies in safety device bypass practices including:

  • inadequate documentation
  • inoperative data history software
  • bypassing more devices than is necessary
  • bypassing devices for longer than necessary
  • missing audit documentation
  • mistakenly bypassing the entire safety system during production

The regulations restricting the bypassing of safety devices are core elements of OCS regulatory and operator management programs. Because they are critical to process safety, these requirements are widely supported and strictly enforced.

Attached is the full NTSB report. Here’s what happened:

  • In May 2024, the Baylor J. Tregre tugboat was towing a platform on the barge MARMAC 27 to Brazos Block 538 in the Gulf of America.
  • The tug capsized in stormy conditions.
  • The 4 crew members were rescued by the Coast Guard.
  • The NTSB determined that the probable cause of the capsizing was “the mate’s inability to maneuver the tow into the wind due to the overwhelming towline force generated by the towed barge during the sudden onset of severe weather, resulting in unrecoverable heeling.”

Comments:

  • Who knew? When a tugboat capsizes while towing a platform on a barge, endangering the crew, that’s a very serious incident. Yet there was no public announcement by the companies involved or the Coast Guard, and there was no media coverage following the incident (May 2024). The NTSB docket includes only the final investigation report.
  • The NTSB report says a production platform was being towed, but it was actually a gas transmission platform owned by Transco Gas Pipe Line Co. There is no production in Brazos Area Block 538, an unleased block.
  • Here and here are bits of information on the Transco’s Brazos Area 538 Platform modification project.
  • Per a 2007 article, Williams’ Seahawk gathering system, which collects deepwater gas production, connects at Brazos Block 538 with a pipeline that transports gas to the Transco processing plant in Markham, TX (see map below).
  • The NTSB report lacks context needed to understand the planning process, organizational factors, and timing/urgency of the project.
  • The NTSB report attributes the failure to the mate’s inability to respond to the weather conditions, but provides no information on the safety management system, risk assessment, job safety job planning process, crew training, and other project management factors.
  • Two of the crew members are suing Trinity Tugs alleging that they suffered personal injuries resulting from the negligence of Trinity and the unseaworthiness of the M/V BAYLOR J. TREGRE.

March Gulf of America oil production was nearly identical to the 2024/2025 average, and the trend line (red) is remarkably flat. However, production remains below the volumes forecasted by EIA and well below those forecasted by BOEM.

It appears that new deepwater production is replacing Gulf-wide production declines, but is not yet sufficient to increase total production. We will see if that changes as the year progresses.

  • March 2025 Gulf of America production: 1.793 million bopd
  • 2024/2025 average production: 1.77 million bopd
  • 2024/2025 average omitting Sept. 2024 (tropical storms): 1.784 million bopd
  • EIA forecast for 2025 (published 9/16/2024): 1.9 million bopd
  • BOEM forecast for 2025 (published in 2022, table below): 2.052 million bopd

Part VIII, Offshore OIl and Gas Leasing, is a good read for those interested in OCS leasing policy. This cleverly crafted part of the bill specifies leasing schedules, streamlines the leasing process, and minimizes litigation risks. Highlights:

  • Minimum royalty rates return to 12.5% from 16.67% post-IRA. (This is good for small, shelf producers.) The maximum rate remains 18.75%.
  • Requires a Gulf of America lease sale by 8/15/2025, a sale by 3/15 and 8/15 in each of the following 14 years (2026-2039), and a sale by 3/15/2040. 80+ million acres must be offered at each sale unless that amount of acreage is no longer available for leasing.
  • The lease form, lease terms, economic conditions, and stipulations 4 through 10 must be the same as for Lease Sale 254 (3/18/2020). Stipulations 1-3 may be updated.
  • Requires seven 1+ million acre (if available) Cook Inlet lease sales from 2026 – 2032. Beginning in 2035, 90% of the revenues go to the State of Alaska.
  • The required lease sales may be in addition to the lease sales held under the 2024-2029 National Outer Continental Shelf Oil and Gas Leasing Program.
  • Adherence with the Biological Opinion shall satisfy the Secretary’s obligations under the Endangered Species Act of 1973 and the Marine Mammal Protection Act of 1972
  • Previous EIS’s for the Gulf of Mexico shall satisfy the Secretary’s NEPA obligation.
  • Consistency determinations prepared by BOEM for Lease Sale 261 for the States of Texas, Louisiana, Mississippi, Alabama, and Florida will satisfy the Secretary’s CZMA obligations.
  • The Secretary may waive any requirement under the Outer Continental Shelf Lands Act that the Secretary determines would delay issuance of a lease.
  • A lease must be issued to the highest responsible qualified bidder not later than 90 days after the sale date.
  • The Secretary shall establish a process through which a Governor may nominate for leasing under a lease sale held under this section an area of the OCS that is adjacent to the waters of the State; and is unleased and available for leasing. If the Governor of a State nominates an area, the Secretary shall include the area in the next scheduled sale. (It appears that this provision applies only to the Gulf of America. Objective?)
  • G&G surveys must be approved within 30 days after a complete application is received.
  • A lease awarded under Lease Sale 259 or Lease Sale 261 shall not be set aside, vacated, enjoined, suspended, or cancelled except in accordance with section 5 the Outer Continental Shelf Lands Act (43 U.S.C. 1334). Also, new terms or conditions may not be added to these leases. (This protects lessees from pending litigation related to these leases).
  • Any action to approve, require modification of, or disapprove any exploration plan, development and production plan, bidding procedure, lease sale, lease issuance, or permit or authorization related to oil and gas exploration, development, or production, or any inaction resulting in the failure to hold a lease sale shall be subject to judicial review only in a United States court of appeals for a circuit in which an affected State is located.
