We have heard plenty about Macondo’s real, imagined, and convenient villains, but very little about the heroes.  Let’s pay tribute to them:

  1. First and foremost the eleven men who lost their lives exploring for energy for our economy and security.  Sadly, were it not for the massive spill, their sacrifice would have received little public attention.
  2. The rescue crews who brought the other 115 workers safely to shore.
  3. The responders who worked under difficult conditions to minimize the environmental effects of the spilled oil.
  4. The relief well crews who demonstrated how complex drilling operations should be conducted.
  5. The ROV and well intervention teams.  The performance of the ROVs and subsea tools is perhaps the biggest Macondo success story.  Their pioneering work will be studied in developing the well intervention, capping, and collection plans that will be a part of future drilling programs.
  6. The people of Louisiana, who despite their personal adversity continue to believe that energy, fishing, and other offshore interests can and must co-exist.
  7. The MMS oil spill research program.  In the lean years following the Valdez oil spill research surge, MMS continued to conduct important burning, dispersant, remote sensing, and mechanical cleanup studies, while upgrading and expanding the use of the nation’s major oil spill response test facility – Ohmsett.
  8. The Unified Command scientists who are providing comprehensive scientific data about the effects of the spill, and refuse to be swayed by sensational media reports.
  9. Oil consuming bacteria!
  10. Others?

G’Day Australia.  There are now only 2 weeks until the Federal election. Ironically, the election, which may have delayed the release of the Montara Inquiry report, will be held on the first anniversary of that blowout.

This report will play an important role in keeping our workers safe, protecting our environment and safeguarding our energy security. Minister Martin Ferguson

BOE fully agrees with Minister Ferguson’s statement about the importance of the Montara Inquiry report and hopes that he or his successor promptly releases the report after the election.  The lessons learned at Montara will not only prevent accidents in Australia, but elsewhere in the world. In light of the disturbing similarities between the two blowouts, it is possible that closer international attention to Montara might even have prevented the Macondo blowout.

  1. Now that the Unified Command has had a couple of days to review the static kill data (which were certainly considered in planning the cementing operation that was concluded yesterday), please provide an update on the latest thinking with regard to the well’s flow path.
  2. Please post a cross section schematic (best estimate) of the well after the completion of yesterday’s cementing operation.

Upstream has confirmed the crane incident on the Jack Ryan during operations offshore Nigeria.

According to a summary incident report into the accident, seen by Upstream, the port aft crane boom and cab, together with the three men, went overboard during load testing.

Upstream understands that the crane boom snapped during the tests.

The Upstream report is consistent with information provided separately by Malcolm Sharples.  One worker is still missing.

Kent Well’s response to a reporter’s question and Colin Leach’s comment on BOE seem to give credence to our suspicion that the flow path for the Macondo well was inside the production casing!  If true, this is enormously significant for the following reasons:

  1. The root cause of Macondo is eerily similar to that at Montara in that oil and gas entered the well via compromised cement in the casing shoe and a failed float.  Did the BP engineers and TO crew even know about Montara?  This shows why accident information must be promptly circulated and brought to the attention of key personnel everywhere in the world. It also demonstrates why the Montara report needs to be released without further delay.
  2. Presumed contributing factors that would be irrelevant or less significant: the long string vs. liner/tieback decision, and the failure to run a Cement Bond Log, additional centralizers, or a lockdown sleeve on the casing seal.
  3. Contributing factors that would have even greater importance: selection of the casing point (integrity at the base of the well), waiting on cement time, timing of the positive and negative pressure tests (this is a topic that warrants much more scrutiny and discussion), and failure to set a cement plug before displacing the mud with sea water.

The vast majority of the oil from the BP oil spill has either evaporated or been burned, skimmed, recovered from the wellhead or dispersed – much of which is in the process of being degraded.

I awoke to an email message from Odd Finnestad linking the BP announcement.  It’s only fitting that Odd delivered the news. He and I have been following Montara and Macondo on a daily basis since August 21, 2009, the day the Montara well blew out in the Timor Sea.  A few thoughts:

  • The real end date for the blowout was July 15th, when the containment cap shut-in the well.  It was an uncertain ending with the capping described as a temporary integrity test and talk about re-opening well vents. Fortunately, good judgement and common sense prevailed, and the well remained shut-in.
  • The efforts to prevent recurrence can now proceed with fewer distractions. It’s difficult to calmly address the issues while video images of oil gushing into the Gulf are being broadcast worldwide.
  • We need to do more than react to Macondo, and every offshore operator and contractor needs to be involved. Only 20% of Gulf of Mexico operators attended a critical industry-government hurricane conference after Katrina and Rita.  (No, I’m not going to stop ranting about this!)
  • Industry needs to look at EVERY aspect of offshore operations, not just the drilling issues associated with Macondo.  Fixing what happened at Macondo doesn’t prevent production, pipeline, and other types of drilling disasters.  Helicopter safety, lifting operations, and workplace safety issues also need to be further addressed.
  • This is a major effort and everyone needs to participate.  If you aren’t committed to improving overall safety performance, in the US and worldwide, you shouldn’t be in the business.

In the less than 3 week period since Macondo was capped, we have transitioned from “doom and gloom” to “all is well.”  What next?

Click to read an interesting USA Today article.

“Oil doesn’t really kill marsh plants,” says John Pardue, director of Louisiana State University’s Hazardous Substance Research Center, who has studied the effects of oil on marshes. “You can put several inches of oil on the vegetation surface and you won’t kill the plants.”

Upstream reports that a worker is missing from Transocean’s Jack Ryan drillship which is working in the Akpo field offshore Nigeria. Two other workers were recovered from the water.  The accident occurred on Saturday, but neither TO nor the Nigerian Petroleum Corporation are providing any details.  Hopefully, more information will be forthcoming in the near future.

Those are the latest official numbers provided by the Unified Command’s Scientific Teams. Once again, no assumptions or calculations are provided. Why? What was the range of estimates for the different methods (videos analyses, reservoir modeling, acoustics, and extrapolations based on recovery volumes)? Show us the data!
