BOE reader Tore Fjågesund of WellBarrier AS has provided this schematic of the Macondo well’s casing program.  The color-coded format simplifies assessment of the barriers, and identifies a probable flow path.  Click here to view the full-size diagram (pdf) – Macondo Well Barriers.

Kudos to Secretary Chu and the Department of Energy for providing online access to Macondo schematics, pressure tests, diagnostic results and other data. This is the type of data that BOE and others have been requesting.  Well done!

By the end of June, BP hopes to have the following arrangements in place:

  1. New well cap with improved sealing mechanism
  2. New seafloor manifold feeding production to a floating production storage and offloading (FPSO) vessel
  3. Shuttle tankers supporting FPSO
  4. Alternative flow path via choke and kill lines back to the Q4000 support vessel

The challenge will be minimizing production system downtime and the associated spikes in spillage, particularly during hurricane evacuations.

When they sheared the riser prior to installing the LMRP cap, the video clearly shows two segments of sheared drill pipe inside the riser.  How that happened is a mystery.  Did the explosion break the work string into multiple segments which fell back toward the BOP?

Dette kan skje igjen (This could happen again)~ Magne Ognedal, Director General, Petroleum Safety Authority Norway

Magne’s quote in the Stavanger Aftenblad acknowledges that tragic accidents like the Macondo/Horizon blowout or Alexander Kielland sinking could happen again (see English translation of full article by BOE Europe Chief Odd Finnestad).  Magne goes on to say:

We must appreciate there are risks associated with our petroleum activities, and in our yearly risk assessments we attempt to put in concrete terms what those inherent risks are.  It is up to our national political system to determine whether this risk picture should be accepted or not.

and

We must endeavor to learn from whatever happens around the world, and if there is something that is also relevant to Norway we must apply those lessons, both regulators and industry

Industry and government officials would be wise to follow Magne’s lead and avoid “can’t happen here” statements.  A few of these statements were made in the US after the Montara (Timor Sea) blowout, and we know how that worked out.

Some very experienced and capable offshore managers have had “there but for the grace of God go I” moments in the wake of this disaster.  They know that this is not the time for boasting, piling-on, or schadenfreude.  Like Magne, real leaders are focused on monitoring the investigations, studying the findings and recommendations, and applying the lessons as necessary to further reduce their operating risks and the risks of others who conduct offshore oil and gas operations.

spill response methods

But I can tell you, based on 21 years’ experience analyzing and observing oil spills, that the best minds in the business are already doing all they can. No special techniques that would work well to clean up the oil in this situation aren’t being tried or planned. There simply are no foolproof solutions. ~ Dagmar Schmidt Etkin

Jason Mathews

Kudos to Jason Mathews, David Dykes, John McCarroll, and their Coast Guard colleagues for their excellent work on the MMS-USCG investigation of the Macondo blowout.  Catch some of the testimony on C-Span.

Good news; production has ramped up nicely via the LMRP cap.

Getting a better picture of the well’s flow rate potential.

We won’t get a good read on the cap’s effectiveness until its placement is adjusted and oil production is stabilized.  Flow to the surface may also be initiated through the choke and kill lines, which could supplement and improve the effectiveness of the cap system.

Update from Deepwater Horizon Response Facebook page:

The LMRP Cap is in place and nitrogen pressure head is slowly being reduced in the riser. Throughout the day, the vents in the cap will be closed as production begins on the surface. The goal is to ensure methane hydrates do not form in the cap.
