Bloomberg report on East Cameron 278 “B”gas leak (90 miles offshore, 170′ water depth):

Apache workers have boarded the platform to seek to contain the source of the gas leak, the U.S. bureau said in an e-mailed statement today. The government said a remotely operated vehicle will monitor conditions to make sure work can occur safely.

The bureau said today that, in accordance with its direction, Apache is continuing preparations for drilling a relief well to stop the leak in the event the platform procedures don’t succeed.

1. This is a surprise.  Does anyone know more about this conference?

U.S. experts will participate in a conference on oil safety in Cuba this April, Reuters reported. The conference comes as the BP disaster on the U.S. side of the Gulf of Mexico is raising concern over the start of offshore drilling in Cuban waters this year. The arrival of an exploratory drilling platform in Cuban waters that had been expected for early this year was reportedly postponed to summer.

2. TheHill.com has a pretty good energy blog of particular interest to Washington-types (you know who you are!).

National oil spill commission co-chairman William Reilly called on the Obama administration to think about negotiating a treaty with Mexico and possibly Cuba that would lay out uniform safety standards for offshore drilling in the Gulf of Mexico.

3. Nothing new is being reported on the blowout/uncontrolled flow/gas leak beneath the East Cameron block 278 B platform that Apache is calling a “water disturbance.” Spin doctors never sleep.

Based on the limited information that is available, well integrity issues loom large and there appear to be some disturbing similarities with the Main Pass 91 blowout in 2007.

One of the better paragraphs I have read since Macondo:

The Deepwater story shows the fight against complacency is a continuous struggle, not a single battle. An executive at another oil major told me the default setting for safety managers should be “chronic unease”. That’s easy to see if you’re a prison governor or lighthouse-keeper. But it should be part of any executive’s attitude. Constant vigilance against, say, new competition, supply chain disruption, or unforeseen technological change is a must for modern managers.

No government regulatory structure alone can guarantee safety in an industry that must constantly adapt new technology to natural variations in drilling sites and unexpected natural phenomena. Oversight must improve, as the Obama administration has made clear, but also every company involved in oil drilling – not just BP – must individually and in concert with others evaluate industry standards and safety research programs. And none should assume that BP’s mistakes could not occur elsewhere. Washington Post

Well said!

In the Wall Street Journal, Rex Tillerson says that the Macondo blowout was not caused by systemic problems within the industry:

The explosion aboard the Deepwater Horizon rig, resulting in the massive oil spill in the Gulf of Mexico, was caused by its operators’ decisions and not by general problems in the oil industry, Exxon Mobil Corp. Chief Executive Rex Tillerson said Thursday.

But then seems to contradict that statement:

“It’s really up to the industry” to make sure regulation is strong and disasters like these don’t happen again, he said.

So, isn’t the second quote acknowledging a systemic problem?

Wall Street Journal

The conclusions of the presidential commission’s inquiry into the causes of the Deepwater Horizon accident published Thursday make it increasingly likely that BP will not be found grossly negligent and will avoid the harshest financial penalties for the Gulf of Mexico oil spill.

Pre-trial orders

Siding with arguments by the Plaintiffs, Judge Barbier concluded that the depositions should go forward in New Orleans, rather than in Houston as preferred by BP.

BP vs. TO vs. Halliburton (quotes from New York Times article)

In a statement on Wednesday, BP noted that the commission had found fault with a number of companies, not only BP, the main owner of the well.

Halliburton said in a statement that it had acted at BP’s direction in preparing and injecting cement into the well. It said tests the panel identified as indicating problems with its cement formula were preliminary and did not contribute to the disaster. Halliburton also criticized the commission for what it called selective omissions of exculpatory material it gave to the panel’s staff.

A spokesman for Transocean said that BP, not Transocean, made the major decisions in the hours before the blowout. “Based on the limited information made available to them, the Transocean crew took appropriate actions to gain control of the well,” the spokesman said. “They were well trained and considered to be among the best in the business.”

What?

The blowout in the Gulf of Mexico could have been prevented if the last-line of defence—the blind shear ram on the blowout preventer, located at the well head on the ocean floor—had activated and crushed the drill pipe. Given the importance of this equipment, and the evident dangers of relying on a single device, we urge the HSE to consider prescribing specifically that blowout preventers on the UK Continental Shelf should have two blind shear rams.

Comments:

  1. The UK government should NOT be commenting on the BOP failure until the US government has completed its forensic testing and investigation.
  2. The Committee has apparently not paid any attention to the testimony on the BOP issues or the other BOP information that has surfaced.  Have they not seen the comments from BP and Transocean or the videos shot on the Q4000?
  3. Would it have been appropriate for the US government to publish a report on Piper Alpha before Lord Cullen had completed his review?

The UK Energy and Climate Change Committee has released its report entitled “UK Deepwater Drilling – Implications of the Gulf of Mexico oil spill.” We’ll post the report as we get a link.

Here’s the gist:

A moratorium on oil drilling in deep waters off Britain would undermine the country’s energy security, according to a report by lawmakers published on Thursday in response to the BP spill disaster last year.

Colin Leach has provided a nice overview of the loss of well control scenarios for a deepwater well (Figure 1), and a concise, but comprehensive, summary of the critical elements of a well control program (Figure 2).   Click on either figure to enlarge.

We appreciate Colin’s continued leadership and initiative on well control issues.
