This hasn't seemed to have gotten much circulation yet, and I think it really needs to. Seems that a crew from Schlumberger, on contract to BP, hightailed it off the platform at their own expense 6 hours before the blowout becuase BP refused their recommendation to shut down the well. This lends more credence to Thom's suggestion that corners were cut because the bigwigs were coming for a vist.
"BP contracted Schlumberger (SLB) to run the Cement Bond Log (CBL) test that was the final test on the plug that was skipped. The people testifying have been very coy about mentioning this, and you’ll see why.
SLB is an extremely highly regarded (and incredibly expensive) service company. They place a high standard on safety and train their workers to shut down unsafe operations.
SLB gets out to the Deepwater Horizon to run the CBL, and they find the well still
kicking heavily, which it should not be that late in the operation. SLB orders the
“company man” (BP’s man on the scene that runs the operation) to dump kill fluid down the well and shut-in the well. The company man refuses. SLB in the very next sentence asks for a helo to take all SLB personel back to shore. The company man says there are no more helo’s scheduled for the rest of the week (translation: you’re here to do a job, now do it). SLB gets on the horn to shore, calls SLB’s corporate HQ, and gets a helo flown out there at SLB’s expense and takes all SLB personel to shore.
6 hours later, the platform explodes."
