Regarding the relief wells, Development Driller III, which is the lead drilling rig for the relief wells is now at 17,780 feet measured depth, within a couple hundred feet of the proposed penetration point of the wellbore.
Admiral Allen: Thank you for reading BOE and responding to our request. You even specified “measured depth!”
Relief Well Team: Great work! Time to finish the job!

Those of us on the “Deepwater Response External Affairs” Mailing List received ten email updates yesterday. Not one included relief well information. The relief well information that has been provided has been inconsistent and contradictory.
Given the importance of these wells and the apparent confusion among observers (a number of whom have contacted BOE), a daily relief well update would be appreciated, at least for the primary well. It would be helpful if the subject line said “relief well update.” This update should include the precise relief well depth, whether the depth is measured (total length) or true vertical, and the point of reference (e.g. below the sea floor). A short summary of the operations over the past 24 hours would also be helpful.

The goal is to eliminate the possibility of what actually could happen not being recognized (at the time of the design). This is achieved by having a core of knowledge against which individual operating companies and outside assessors can assess designs and approaches. Communication between the operator and the “knowledge core”would be confidential as long as a well control incident did not occur. The format of this “knowledge core” is such that it eliminates the “committee think” within an operating company where a dissenting individual (who is actually knowledgeable) can be overruled by a committee vote.

bottom of the flowing Macondo well
Based on the latest information provided by Admiral Allen, the relief well has reached 11817′ below the sea floor and is thus only 273′ above the 9 7/8″ casing shoe on the flowing Macondo well. After drilling another 200+ feet, they will open (enlarge) the relief well and install a 9 7/8″ liner. They will then drill a few hundred feet beneath the liner and intercept the flowing well. They will presumably kill the flow in the annulus outside the casing (assuming that is a flow path) with heavy mud before milling into the 7″ casing, killing any flow inside that casing, and plugging the well bore with cement. Stay tuned.

DD3
BOE doesn’t really care about where LeBron James chooses to play basketball, but we are big fans of the team on the Development Driller III or DD3. The DD3 crew, some of whom are Deepwater Horizon survivors, is ahead of schedule and predictions for an early intercept and well kill are approaching irrational exuberance levels. This may be the most important well in history, and crew has responded to the challenge.
After the DD3 crew finishes the job, we owe them a victory parade in New Orleans. “Throw me somethin’ mista! 🙂

Interesting comments from Jane Cutler, CEO of Australia’s National Offshore Safety Petroleum Safety Authority, in NOPSA’s excellent newsletter:
The incidents in the Gulf of Mexico (Deepwater Horizon) and at the Montara wellhead platform are different in many respects, particularly in technical matters. However, they share some common factors prompting regulatory action.
I agree entirely with Ms. Cutler. International regulators and operators must work in concert to address and resolve these issues.

BP has released a slide presentation and animation on the relief wells showing the intercept point below the 9 7/8″ casing shoe. The exact sequence of operations once they reach the intercept point will be interesting to observe. They should encounter flow when they reach the 7″ casing annulus (assuming that is a flow path; there still seems to be some uncertainty in that regard). Will they attempt to kill the flow in the annulus before milling into the 7″ casing? Is there flow inside the 7″ casing via channels in the casing shoe? Is there drill pipe inside the casing?

The House Energy and Commerce Committee has posted a discussion draft of the Blowout Prevention Act of 2010. A hearing is scheduled for 30 June.
