Per the DOI regulatory agenda published on 7/27/2023 (excerpt below), the final BSEE well control rule was published in June. Of course, that did not happen, but the update tells us that the final rule should be published soon. The delay is probably in the internal review process which moves at the pace of continental drift 😉.

BOE comments on the proposed rule are attached here.

12. Oil and Gas and Sulfur Operations in the Outer Continental Shelf-Blowout Preventer Systems and Well Control Revisions [1014–AA52]

Abstract: This rulemaking revises the Bureau of Safety and Environmental Enforcement (BSEE) regulations published in the 2019 final rule entitled “Oil and Gas and Sulfur Operations in the Outer Continental Shelf-Blowout Preventer Systems and Well Control Revisions,” 84 FR 21908 (May 15, 2019), for drilling, workover, completion and decommissioning operations. In accordance with Executive Order (E.O.) 13990 (Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis) and the E.O.’s accompanying “President’s Fact Sheet: List of Agency Actions for Review,” BSEE reviewed the 2019 final rule and is updating to subpart G of 30 CFR part 250 to ensure operations are conducted safely and in an environmentally responsible manner.

In the Gulf of Mexico, deepwater leases produce large volumes of oil and gas from only a few surface facilities that are relatively distant from shore.

The Gulf of Mexico encompasses approximately 617,800 square miles and stretches 932 miles across from east to west. BOEM’s deepwater bathymetry grid of the northern Gulf of Mexico, created using 3D seismic data, covers more than 90,000 square miles (colored area in figure below). In this vast area, only 59 surface facilities produce ~1.7 million bopd and 2.2 bcfd.

The 59 deepwater facilities are comprised of:

  • 6 fixed platforms in water depths from 1023 to 1353′
  • 2 compliant towers (1648 and 1754′)
  • 17 tension leg platforms and mini-TLPs (1500-5185′)
  • 18 spars (1930-7835′).
  • 13 production semisubmersibles (aka floating production units; 3280-7400′)
  • 2 fpso’s (8300 and 9560′) and a mobile production unit (2200′)

Attached is a settlement agreement between NOAA and 4 NGOs that could have major implications for deepwater oil and gas operations in the Gulf of Mexico.

As background, the Rice’s Whale (formerly Bryde’s whale) area has been expanded (see map above) such that it fences off deepwater leases by creating a barrier to vessel transportation. The expansion is based on a single study that concluded that Rice’s whales were “the most plausible explanation” for moan calls observed in the northwest GOM shelf break area. No Brice’s whales were sighted in the expanded area during this study. The authors do point to a 2017 sighting offshore Corpus Christi, which is apparently the only actual sighting of a Brice’s whale along the NW GoM shelf break.

The settlement agreement commits BOEM, presumably with their concurrence, to exclude the expanded area from future leasing, to issue a Notice to Lessees and Operators (exhibit 1 below) and to attach stipulations to new leases (exhibit 2). Because BOEM’s authority to impose major new requirements without proposing a regulation for public review and comment is questionable, the Notice (NTL) describes the restrictions as “recommended measures.” However, the liability risks associated with the failure to comply with this “guidance” would be unacceptable to most companies. Adding to the muddle, the language in the lease stipulation differs by making it perfectly clear that compliance is required.

The most troubling restriction from an operational standpoint:

To the maximum extent practicable, lessees and operators should avoid transit through the Expanded Rice’s Whale Area after dusk and before dawn, and during other times of low visibility to further reduce the risk of vessel strike of Rice’s whales.

Comments:

  • Deepwater facilities are typically far from shore, and a requirement to transit only between dusk and dawn, particularly in the winter, is unrealistic and onerous. This is further complicated by the speed limit provision.
  • Those who have worked offshore know that periods of low visibility are unpredictable and can extend for days. The low visibility transit restriction is thus highly punitive and increases operational risks on the vessels and at the facilities they serve.
  • The vague “to the maximum extent practicable” caveat provides little comfort for planners, managers, and crews, and is a de facto acknowledgement that the requirement is unreasonable.
  • These restrictions, coupled with the required Automatic Identification System data, open the door to endless challenges, especially given the keen interest of the litigious organizations that are parties in the settlement agreement.
  • Deepwater GoM operations are few in number and highly dispersed, which is a more important mitigating factor than those included in the agreement. More on this tomorrow.
  • In addition to the deepwater operations that will be much more difficult to supply, there are currently 81 production platforms within the expanded Rice’s whale area (100 to 400 m water depth).These include important facilities like Amberjack, Cognac, Cerveza, and Lobster. What are the implications for these platforms? Will they be required to have full-time whale observers? Can they only be supplied during daylight hours with good visibility? Why not consider using these platforms as bases for more definitive studies?
  • Further to the previous point, there are 103 existing leases in the 100-400 m depth zone that is now excluded from leasing? 90 of these leases are still in their primary term, and 21 were issued in the past 2 years. How will the contractual rights of these leaseholders be protected? (In fact, the value of all 1550 active leases in >100 m water depth is affected by this agreement.)
  • Have BSEE and Coast Guard been consulted on the practicality and safety implications of these requirements?
  • Deepwater operations have been ongoing in the GoM for 50 years, and there is no apparent evidence of impacts to this species. Why can’t the consultation process and any necessary followup studies be completed before decisions are made regarding operating restrictions?
  • These types of restrictions, coupled with the diminished state of the Strategic Petroleum Reserve and tightening oil markets, raise serious energy security and economic concerns.

Finally, BOEM’s third footnote in the NTL (pasted below), doesn’t demonstrate great confidence in the need for the onerous requirements that are being imposed.

This is not meant to be construed as a blanket determination as to whether BOEM, at present, has determined that there is a “reason to believe” that incidental take may occur, within the meaning of the ESA, the consultation regulations, or BOEM’s regulations. Those decisions will be made on a case-by-case basis in accordance with BOEM regulations referenced below.” Comment: Huh??? How are these blanket restrictions case-by-case, and how are they being imposed without public review?

BOEM’s Final Sale Notice for the upcoming Gulf of Mexico wind auction identifies 3 lease areas (see map below). Wind operations in these areas should not significantly conflict with other GoM activities, including oil and gas operations.

Those who followed Exxon’s recent lease acquisitions may be amused by the map below from BOEM’s siting analysis document. The 94 Exxon leases acquired at Oil and Gas Lease Sale 257 (yellow blocks) are misidentified as “Carbon Capture Lease Blocks.” As has been discussed at length on this blog (most recently here), Sales 257 and 259 were oil and gas lease sales. Although Exxon’s intentions are now well known, they may not conduct carbon sequestration operations on these leases unless they are competitively reissued or converted. (Is BOEM’s siting document implying that conversion of the Exxon leases is a fait accompli?) The regulations for such conversions, and for CCS operational activities, have yet to be promulgated. A draft of these regulations is expected later this year, and the comments should be spirited and diverse.

World Bank flaring data have some limitations as discussed in a previous BOE post. However, they provide an objective means of estimating and comparing flaring volumes worldwide, and therefore merit close attention.

The latest World Bank data tell us that significant gas flaring issues persist. Worldwide, 138,549 million m3 of gas were flared in 2022. This equates to a massive 4 tcf, the equivalent of the reserves in a major gas field and more than 5 times the total gas production in the Gulf of Mexico in 2022.

The top ten “flarers” are listed below. Each of these fields flared from 19 to 42 bcf. For comparison, the top ten GoM gas producers in 2022 produced 10 to 57 bcf, so single fields are flaring more than GoM companies are producing in total. Assuming for discussion purposes a gas-oil ratio of 1000 cu ft/bbl, all of the gas associated with 19 million to 42 million barrels of oil production was wasted from each field.

Posted below are the World Bank’s flaring intensity data (m3 of gas flared per bbl of oil produced) for the 10 countries with the highest flaring volumes. Venezuela’s flaring intensity rose to 44.6 m3/bbl in 2020, before declining moderately the following 2 years. 44.6 m3/bbl equates to 1575 cu ft/bbl. This gas flaring to oil production ratio implies that a very high percentage of Venezuela’s associated gas production was flared.

Here in North America, we have flaring issues of our own. Mexico’s Cactus Field is a top ten flarer (first table above) with 534.5 million m3 flared in 2022. The World Bank also lists 6 Permian Basin fields with >50 million m3 of gas flared in 2022.

Zeroing in on the US/Canada offshore sectors, fields with >1 million m3 of gas flared (2022) are listed below. Four of the top 7 are offshore Alaska and Newfoundland where the gas cannot currently be marketed and reinjection, field use, and flaring are the only options. Can production from these fields be better managed to reduce flaring volumes?

The extraordinary 1.1 bcf of gas that was flared at the Shenzi field may help explain the large (1 bcf) increase in oil well gas flaring in the Gulf of Mexico in 2022. Based on the World Bank data and ONRR data for the GoM, Shenzi accounted for 16% of GoM oil-well gas flaring in 2022. As noted in that post, more regulator/industry transparency on lease and field specific flaring is needed. ONRR’s posting of flaring and venting data is a positive step, but it doesn’t include lease specific data and doesn’t explain major flaring episodes.

MROV – Mean of the Range-of-Value

Observations:

  • Keathley Canyon (KC) Block 96, the tract receiving the highest bid in the entire sale ($15,911,947 by Chevron), had a BOEM MROV of only $576,000. Clearly, Chevron and the government have a very different view of the value of this tract. BP was the second bidder for KC 96, and their bid ($4,003,103) was also considerably higher than BOEM’s MROV. This one will very interesting to follow.
  • The only bid that was rejected in Sale 257 was the BP/Talos bid of $1.8 million for Green Canyon Block 777. BOEM’s MROV in the Sale 257 evaluations was $4.4 million. BP again bid on GC 777 in Sale 259, but their bid was only $583,000 (even though BOEM’s Sale 257 evaluation was public information). BOEM’s MROV was reduced only slightly to $4.2 million, and they again rejected BP’s bid. We’ll see what happens in the next sale.
  • 51 of the 230 accepted bids were >$1 million, all for deepwater tracts. All of the rejected bids were for deepwater tracts, and a higher percentage (4/14) were >$1 million. This makes sense given that the higher potential prospects are in deepwater.
  • These results demonstrate again that resource evaluation is far from an exact science. BOEM is not selling barrels of oil and cubic feet of gas. BOEM is evaluating prospects, and companies are bidding on the opportunity to explore these prospects.
  • Bidding strategies differ; the more companies participating, the better the long-term prospects for the OCS program.

ENERGYWIRE has reported that the Department of the Interior will publish the legislatively mandated carbon sequestration rule later this year. Given that even close followers of the OCS program were completely unaware of the enabling legislative provisions prior to their enactment, the proposed DOI rule will provide the first opportunity to formally comment.

Within the oil and gas industry and the environmental community, there are considerable differences of opinion about carbon sequestration in general, and more specifically, offshore sequestration. All interested parties are encouraged to submit comments on these important regulations.

Some background information on the sequestration legislation and subsequent actions:

Exxon and other companies intend to commercialize carbon sequestration, and Exxon projects an astounding $4 trillion CCS market by 2050. Such a market will of course be dependent on mandates and subsidies, and the costs will ultimately be borne by taxpayers and consumers.

Is it not a bit unsavory and hypocritical for hydrocarbon producers to capitalize on the capture and disposal of emissions associated with the consumption of their products? Perhaps companies that believe oil and gas production is harmful to society should exit the industry, rather than engage in enterprises that sustain it.

For the first time in the history of the US offshore oil and gas program, taxpayers will be funding the plugging of OCS wells. This should be viewed as a collective failure by government and industry. Nearly 34 years have passed since the Alliance bankruptcy, the first of many wake-up calls, and we still haven’t figured this out.

Per BSEE’s recent announcement, Federal funds will be used to plug wells in the Matagorda Island (MI) area of the Gulf of Mexico (see map below). Based on a BSEE presentation and BSEE borehole data, these wells were drilled by Matagorda Island Gas Operations LLC, a company that filed for bankruptcy in 2014.

Prior to the bankruptcy filing, Matagorda Island Gas was cited for 112 violations on 108 inspections. This INC/inspection rate is approximately double the Gulf of Mexico (all operators) rate in a typical year (0.52 in 2022), and is 4 to 25 times higher than the rate for the 2022 Honor Roll companies.

In a draft rule published on June 29, 2023, BOEM proposes to discontinue using a company’s record of compliance in determining the need for supplemental financial assurance for decommissioning. BOEM’s full explanation for this surprising change is pasted at the end of this post.

Opposing view:

  • BOEM should be more attentive, not less, to safety performance and compliance data. If they were, taxpayers would have been better protected from the risks associated with the lease acquisitions by Fieldwood, Cox, Black Elk, Signal Hill, and others, and their subsequent bankruptcies.
  • Safe operations, as reflected in compliance and performance data, are critical to a company’s financial success.
  • BOEM wrongly infers that Incidents of Noncompliance (INCs) are solely dependent on the number and complexity of facilities. Decades of normalized compliance data have told us that there are marked differences among operators in terms of compliance and safety performance. Companies at the bottom of the performance table don’t usually survive.
  • Accidents are not mere matters of chance; management and culture matter.
  • Honor Roll companies, large and small, have superior compliance records, and in 2022 these companies had 50-90% fewer INCs/facility-inspection than the Gulf of Mexico average.
  • Does BOEM expect noncompliance leaders to be concerned about decommissioning obligations? The record shows that they are not.
  • Cox’s 2023 bankruptcy was predictable given their past safety performance. In 2022, Cox was a violations leader by any measure, and was responsible for 9 of the 30 safety incidents that were significant enough to require investigation by BSEE.
  • Fieldwood’s terrible 2021 safety performance has been discussed, and there was ample evidence of performance problems prior to their bankruptcy declaration in 2018. In 2016 and 2017 Fieldwood was, by far, the GoM violations leader with 818 INCs, 401 of which required a facility or component shut-in.
  • Ironically (or maybe not), the only other company that was even in the same noncompliance ballpark as Fieldwood in 2016 and 2017 was future Cox affiliate Energy XXI GOM. Energy XXI earned 465 INCs (240 shut-ins) during that 2 year period. Did BOEM object to or otherwise comment on the 2018 Cox-Energy XXI merger?
  • Black Elk Energy was new in 2007 and quickly became a violations leader. Between 2010 and 2012, BSEE cited Black Elk 415 times. 218 of these violations were serious enough to require facility or component shut-ins. On November 16, 2012, explosions at Black Elk’s West Delta 32 platform killed 3 workers, and 2 others suffered severe burns. Criminal charges and a complex bankruptcy followed. BSEE records show 1107 INCs during the company’s short history, 464 of which required facility or component shut-ins.
  • The rapid growth of Fieldwood, Cox, and Black Elk was in part facilitated by lax lease assignment and financial assurance policies. Operating companies should have to demonstrate that they can operate safety and comply with the regulations before they are approved to acquire more properties.
  • The Signal Hill saga was documented nearly 2 years ago, and none of the questions raised in that post have been answered. Violations data and inspector feedback predicted the Signal Hill/POOI failure. Nonetheless, and despite the objections of regional staff, Signal Hill was allowed to tap into its decommissioning account to cover operating expenses. Responsibility for decommissioning Platforms Hogan and Houchin is still uncertain.
  • Bankruptcy has been used to avoid or transfer decommissioning obligations. In that regard, Chevron’s comprehensive objection to Fieldwood’s restructuring plan is telling.
  • Given that BSEE, not BOEM, is responsible for safety and compliance, I sincerely hope that regulatory fragmentation was not a factor contributing to BOEM’s decision to discontinue the use of compliance data in determining financial assurance needs.

BOEM’s explanation for the proposal to eliminate the record of compliance criterion:

BOEM also proposes to eliminate the existing “record of compliance” criterion found in the current version of § 556.901(d)(1)(v). BOEM has determined that the number of INCs a company receives correlates with the number of OCS properties it owns, not its financial stability, and therefore, BOEM has concluded that it is not an accurate predictor of its financial health. BOEM reviewed BSEE’s Incidents of Non-Compliance (INCs) records and its Increased Oversight List, which represent BSEE’s cumulative records of violations of performance standards on the part of OCS operators and lessees and determined that the number of incidents of non-compliance typically increases with the size and complexity of the operator’s or lessee’s operations, including the ratio of incidents to number of components. Because larger companies (regardless of credit score) tend to have more properties and components and therefore more INCs, BOEM determined that record of compliance criterion does not accurately predict financial default. BOEM’s review of this information confirmed the feedback BOEM received in response to the 2016 NTL, namely that companies with a large number of properties and facilities tended to receive a large number of INCs and had more individual properties on the Increased Oversight List. BOEM specifically requests comments regarding the use of fines and violations as a criterion in the determination of a company’s ability to fulfill decommissioning obligations, and any data or analysis addressing any correlation between the number of violations and the risk of financial default. BOEM also requests comments on whether the elimination of the INC’s criteria would create a disincentive to comply with regulations. BOEM also requests comment on whether or not the cost of decommissioning is likely to increase based on the type, quantity, and magnitude of previous violations.

On a related note, BOEM/BSEE should consider a followup to the John Shultz thesis which found that INCs are a very good predictor of accidents and spills.

Some preliminary thoughts about BOEM’s proposed revision to the decommissioning financial assurance regulations for US offshore oil and gas operations:

  1. BOEM has rather surprisingly proposed to eliminate consideration of a company’s compliance record in determining the need for supplemental financial assurance. An opposing view will be posted tomorrow.
  2. If a lease has proved reserves with a value of at least three times that of the estimated decommissioning cost, no supplemental financial assurance would be required. Comparing two imprecise and variable estimates is neither a simple nor reliable method for determining the need for supplemental financial assurance. BOEM should look at the history of the Carpenteria field (Santa Barbara Channel) and the reserve estimates that were provided to discount decommissioning risks. More on this at a later date.
  3. Transferor liability applies only to those obligations existing at the time of transfer; new facilities, or additions to existing facilities, that were not in existence at the time of any lease transfer are not obligations of a predecessor company and are considered obligations of the party that built such new facilities and its co- and successor lessees. This is a good policy, but is difficult to implement. Some of the complexities may need to be addressed. More later.
  4. The “reverse chronological order” provision was withdrawn in April, so there is no defined process for issuing decommissioning orders to predecessor lessees. Is it good policy to first issue such orders to companies who may have owned leases decades ago, in some cases prior to the establishment of transferor liability in the 1997 MMS “bonding rule?”
  5. The proposed rule would clarify that BOEM will not approve the transfer of a lease interest until the transferee complies with all applicable regulations and orders, including the financial assurance requirements. BOEM needs to be firmly enforce this policy. See tomorrow’s post.
  6. The proposed rule would not allow BOEM to rely upon the financial strength of predecessor lessees when determining whether, or how much, supplemental financial assurance should be provided. This is a good provision.
  7. BOEM proposes to use the P70 probabilistic value to set the amount of any required supplemental financial assurance. These estimates do not seem sufficiently conservative to protect other parties and the public in the event of default. This is particularly true after storm damage which can increase plugging costs more than tenfold.
  8. The probabilistic cost estimates were updated in 2020 and are based on data submitted subsequent to 2016 and 2017 NTLs. How often will these estimates be updated?
  9. The final rule should specify that funds may not be withdrawn from decommissioning accounts for operational purposes, and that BOEM approval is required for such withdrawals.
