  1. 5 workers killed – 4 contractors and one Pemex employee
  2. 6 workers injured, one in critical condition
  3. 2 workers are missing
  4. The fire occurred in the power generation and compression area of the platform
  5. Contractors Cotemar and BMCI were performing maintenance at the time of the incident
  6. The fire has now been extinguished
  7. No reports of an oil spill
  8. Massive loss of production – 421,000 BOPD shut-in

Defensive and rather shameful comments by the CEO:

“There is not a problem of lack of investment, there is not a problem of lack of resources,” Romero said. “The oil industry is a risky industry. We have had accidents, which in numbers are less than in previous years.”

Comprehensive and timely incident data are critical for risk assessments, preventing recurrences, training and safety management programs, assessing the performance of the industry and individual companies, and driving safety culture. The National Academies 2021 review of BSEE’s inspection program included a number of recommendations related to data management including this one:

Recommendation 2. To further its goal of increasing data transparency and facilitating its internal and external use, BSEE should invest in more advanced and creative data collection, analytic and visualization tools, and infrastructure; corresponding data management, analysis, and evaluation capabilities among its personnel; and an outward-facing, online data system that can be navigated with ease and kept current across all fields for the purpose of encouraging and facilitating safety analyses.

National Academies Report, 2021

Unfortunately, BSEE’s incident data are not updated and posted in a timely manner. As we approach September 2021, the 2020 incident statistics are still not publicly available. These incidents include at least one rig fatality that neither BSEE nor the Coast Guard announced at the time of occurrence one year ago today (8/23/2020) or subsequently. The only public information about this fatality is the following self-serving statement by the operator:

“This is a routine operation that was executed with no time pressure as the rig disconnection had been decided well in advance,” Total said.

Upstream

A 37-year old man died, but according to the operator there is nothing to see here. This is not the type of statement you would expect from a company with a leading safety culture.

The keystone of BSEE’s primary mission, protecting workers and the environment, is timely incident information that is regularly reviewed and updated. Continuous improvements in safety are dependent on continuous improvements in data management and analysis. BSEE can do much better, as can other regulators, the offshore industry, and those of us who are interested and concerned observers.

For the better part of two months now, four of the five wind turbines at America’s first offshore wind farm haven’t been spinning. 

Workers at the Merkur wind farm in the German North Sea found signs of stress fatigue on the support structures of the “helihoist” platforms on some of the project’s GE Haliade turbines. 

The Providence Journal, 8/14/2021

Comments:

  1. Ørsted was prudent to shutdown the turbines to conduct precautionary inspections.
  2. Press reports imply that Ørsted was slow to advise the public about the reasons for the shutdown.
  3. The shutdown raises questions about the reliability of wind-centric regional power grids.
  4. Given the questions that have arisen regarding the regulation of offshore wind projects (this wind farm is in Rhode Island State waters), the absence of any comments from State and local officials was noteworthy. It’s unclear what, if any, role the State had in the shutdown decision.
  5. Hurricane Henri may give the wind farm a bit of a test this weekend.

The Department of the Interior (Interior) confirmed today that the Department of Justice (DOJ) has appealed the preliminary injunction entered by the district court in Louisiana v. Biden, which enjoined Interior from implementing the pause in new federal oil and gas leasing 

DOI statement 8/16/21

The day after the fall of Kabul and 5 days after the White House urged OPEC to increase production, DOI reiterated the Administration’s support for a pause in oil and gas leasing on Federal lands (including the OCS). Given the increased risk of long-term oil supply uncertainty, rigid support for a blanket leasing pause would not seem to be a prudent policy position at this time.

DOI argues that greenhouse gas (GHG) emissions must be curtailed, but reductions in domestic production would increase the demand for imports with higher GHG intensity. Reductions in deepwater Gulf of Mexico production, which has low GHG intensity and other environmental advantages (few dispersed facilities distant from shore), would be particularly detrimental. Of course, any public policies that discourage natural gas production would also have distinct air emissions costs.

If supply restrictions increase the price of oil, net reductions in oil consumption and GHGs could be achieved. However, as evidenced by the recent appeal for increased OPEC production, higher oil prices are not consistent with Administration policy.

Challenger Energy Graphic

The only 2021 Atlantic drilling activity offshore North America and south of Newfoundland was in Bahamian waters. Yesterday, Challenger Energy (formerly Bahamas Petroleum) provided an interesting update. Some highlights:

  1. The Perserverance I well was drilled approximately 20 miles from the Bahamas-Cuba maritime border, in water 518 meters deep. This was the first exploration drilling in The Bahamas since the mid-1980s, and the first test of any prospect located in deeper waters off the shallower water carbonate banks.
  2. There were no safety or environmental incidents.
  3. The well was plugged and secured in accordance with international and BSEE standards.
  4. Challenger advised the Government of The Bahamas of its intent to renew its exploration licences. 

Geologic summary:

Perseverance-1 reached total depth of 3,905 metres, having intersected five Albian, Upper Aptian, and Mid-Aptian horizons of interest. Post-drill analysis of the well has confirmed the geological risk elements for trap, seal and reservoir were present in the Lower Cretaceous carbonate play. Perseverance encountered high quality reservoirs in the targeted Lower Cretaceous carbonate closures, with thick sequences of evaporites providing effective seals. Depth and thicknesses of reservoir sections encountered were generally as prognosed pre-drill, and reservoir porosity was likewise generally in line with pre-drill expectations (in the range of 10% to 20%).

The presence of hydrocarbons was encountered at various horizons, indicated by elevated gas chromatography readings detected continually during drilling, generally increasing with depth and through the deeper Aptian reservoir column in particular. Oil was identified from high oil saturation values from logs in a number of reservoir sections, thus verifying the existence of a working Lower Cretaceous petroleum system and reservoir quality sequences in the Aptian.

Although hydrocarbons were present, these were not in commercial quantities, with the source quality and migration interpreted as being the primary reason for this non-commercial well outcome.

Petrophysical analysis of the well logs have confirmed high quality reservoirs down to the base of the well with no significant deterioration in porosity with depth, indicating the potential for high deliverability reservoirs in the underlying Jurassic formations.

In aggregate, the analysis of the data from Perseverance-1 drilling is broadly indicative of increased potential for oil in the underlying Jurassic interval (which was not penetrated by Perseverance-1). In particular, the relatively cool well temperatures place the postulated Jurassic source rock (producing in nearby Cuba and the US Gulf of Mexico) in the oil window, thus oil generative.

A recent Washington Post (WP) article, based in part on a March 2021 General Accountability Office (GAO) report, raises interesting pipeline decommissioning issues, but might benefit from some additional context, which I have attempted to provide below:

  • Decommissioning liability issues are not simply a matter of “companies trying to get out of that obligation.” Much of the complexity is associated with decades-long chains of lease ownership and the respective responsibilities of prior lessees. Pertinent questions include the following:
    • If a company sold a lease decades ago and there have since been multiple owners, to what extent is the original owner still liable for decommissioning lease facilities? (Note that guidance from the Federal government has not been entirely consistent over the decades.)
    • If current leaseholders fail to fulfill their obligations, who is next in line and why?
    • To what extent are prior lessees liable for wells and structures constructed subsequent to their ownership?
    • Knowing that decommissioning costs can vary significantly, what amounts of security should be required? How should these funds be protected or managed? Should an assigning company also collect funds to protect their interest?
    • How do inconsistent Federal policies and financial assurance requirements, and improper practices by subsequent owners, affect the liability of prior lessees? In that regard, the case of Platforms Hogan and Houchin in the Pacific OCS Region is interesting and pertinent.
  • Per the WP, “Federal regulations require the removal of offshore pipelines once they are decommissioned, but the rules are rarely enforced.” This statement is doubly incorrect.
    • 30 CFR § 250.1750 provides for decommissioning pipelines in place when the Regional Supervisor (BSEE) determines that the pipeline does not constitute a hazard (obstruction) to navigation and commercial fishing operations, unduly interfere with other uses of the OCS, or have adverse environmental effects. The consensus opinion of the regulators’ engineers and scientists has been that the safety and environmental risks associated with pipeline removal were significantly greater than those for decommissioning in place in accordance with the procedures specified in 250.1751.
    • The comment about enforcement is unfounded. BSEE and its predecessors have strictly enforced decommissioning requirements despite the challenges related to inconsistent policy direction, industry downturns, and hurricane damage. BSEE has an effective program to ensure that idle wells are plugged and platforms are removed in a timely manner. For this reason, 3315 platforms have been removed since 2001; 1933 since 2010. Only about 1800 platforms remain. This very significant loss of habitat is a concern to fishing organizations, another factor that complicates decommissioning policy.
  • In situ decommissioning of buried or trenched offshore pipelines is the standard throughout the world. The seafloor disturbance and safety risks associated with the removal of such pipelines are universally viewed as unwarranted. The pipeline decommissioning procedures followed elsewhere are similar to those described in 30 CFR 250.1751. In the Gulf of Mexico, pipelines installed in less that 200′ of water are typically buried (30 CFR 250.1003) to minimize interference with commercial fishing and other activities.
  • The decommissioning of wind turbines, which are typically more densely located and closer to shore, and their attendant power cables and substructures, will also be challenging. In their 9/16/2019 Congressional testimony, the Responsible Offshore Development Alliance expressed concern about the practice of leaving structural foundations when turbines are abandoned.

In remarks to the WP, Syed Khalil, a coastal restoration geologist for the State of Louisiana, commented that they have enough sand to meet their short term needs, but future needs were a major concern. The Gulf of Mexico Offshore Sand Management Working Group would seem to be the best mechanism for timely action and a workable, long-term action plan. The minutes of their meetings are quite instructive. Rulemaking is not a solution unless the parties want to tie their fate to both the 25 year pipeline rule rewrite (draft published in 2007, another draft coming? final?) and the contentious and similarly interminable financial assurance rule.

Watching Kevin Costner at the beginning of the “Field of Dreams” game in Iowa reminds me that Kevin visited the MMS Ohmsett facility in New Jersey in 1999. He and his brother had developed an oil purification system that was being tested at Ohmsett (“Tank of Dreams?”). In the picture below, Kevin is flanked by Ohmsett Manager Bill Schmidt and Engineer Dave DeVitis. Were it not for the heroic efforts of Ed Tennyson and other MMS employees, Ohmsett would have been abandoned in the 1980s. More on that in a later post.

Déjà vu?

The White House urged OPEC to boost oil production Wednesday, saying recent planned increases are insufficient as countries around the world seek to emerge from the Covid-19 pandemic.

In the early 1990’s, Department of the Interior (DOI) and Department of Energy (DOE) leadership dabbled at re-branding the OCS Oil and Gas Program by reversing the order of the words. Clever? Perhaps by Washington public relations standards. One senior manager even changed his license plate from “OCS OIL” to “MMS GAS” (not much competition for those tags 😃). Technical staff were less enthused about this simplistic marketing gimmick that misrepresented the historical and scientific facts about oil and gas production. For many years, natural gas was a byproduct of oil production that was commonly flared. (This practice continues in some regions of the world, although to a lesser extent than in the past.)

Understandably, the Oil and Gas Journal wasn’t very impressed by the change. I saved a copy of their 1/24/1994 editorial (attached) on the subject. Per the OGJ:

We at the Journal love natural gas. But that doesn’t warrant an attempt to repeal the laws of nature and ignore the weight of tradition by renaming everything “gas and oil” this and that.

John L. Kennedy, Editor, Oil and Gas Journal, 1/24/1994)

To their credit, BOEM and BSEE web pages and announcements during recent administrations (both parties) indicate a preference for the more traditional “oil and gas.” (The DOE website largely ignores the existence of either oil or natural gas.) Surprisingly, the American Petroleum Institute (API), an industry trade organization with more than 100 years of history, is now consistently using “natural gas and oil.” This rearrangement of words is not entirely consistent with the interest of API’s members. In the offshore sector, the primary interest of API members is in finding and producing oil. if you think otherwise, look at the EIA GoM gas production data. Most of the Gulf’s declining gas production is now associated with deepwater oil production, and BSEE rightfully requires that this gas be used for fuel or transported for sale. Similarly, gas is a secondary consideration for API members exploring in Alaska given that 35 trillion cu ft of North Slope gas still awaits a pipeline.

Oil companies, and those who represent them, should be proud of their current and historical role in producing oil (and gas) for our economy, security, and way of life; and of the men and women who have toiled to locate and produce petroleum resources for the benefit of society. Are there better energy alternatives? Perhaps, but issues with these alternatives remain to be resolved, and oil and gas will continue to be important. Let’s focus on producing these resources as safely, cleanly, and reliably as possible.
