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:
- 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.
- 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.
- 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.

Click to read the full “Oil Budget” report (just released).
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!

Per Admiral Allen, BP will be starting the injection test (aka static kill, bullheading operation, topkill) this afternoon.

Link to EPA Release. The results are not surprising.
These results confirm that the dispersant used in response to the oil spill in the Gulf, Corexit 9500A, is generally no more or less toxic than the other available alternatives.
Good, timely work by EPA. Also:
EPA believes dispersants should only be used sparingly and when absolutely necessary. Since the well was capped, only 200 gallons of dispersant have been applied to the Gulf, but constant monitoring continues.

Per Nola.com, the Bayou St. Denis blowout has been capped.
“The Unified Command was able to accomplish this in less than a week due to the fantastic cooperation between the federal, state and local officials and efforts of the contractors,” Capt. John Arenstam, the Coast Guard Federal On Scene Coordinator, said in a news release.
The fact that this incident occurred at all is not so fantastic. The Coast Guard is investigating. We look forward to seeing the report.
