Bud's Offshore Energy (BOE)

Platts has an interesting report on yesterday’s hearing:

Guide said the decision to use a long string of casing instead of a liner
was made because it provided better long-term well bore integrity, not because a liner would have cost an additional $7 million to $10 million. He said the liner would have added only one additional barrier in the well.  John Guide, BP’s Well Team Leader 

Comment:  One additional barrier is very significant when you only have 2 others and there are issues with the primary barrier (production casing cement).

Jason Mathews, a BOEM panel member, asked Guide if he knew that in the past year, Schlumberger had been brought to rigs 74 times for cement bond logs, and only three times they had been sent away without doing the logs; in two instances BP, sent the crews away.

Comment: Interesting statistic; good research by Jason and the BOEMRE team.
