Rig survivors: BP ordered shortcut on day of blast - CNN.com

An interview with Anderson Cooper on CNN brings to light the following "issue".

The morning the Deepwater Horizon oil rig exploded, a BP executive and a Transocean official argued over how to proceed with the drilling, rig survivors told CNN's Anderson Cooper in an exclusive interview. The survivors' account paints perhaps the most detailed picture yet of what happened on the deepwater rig -- and the possible causes of the April 20 explosion.
The BP official wanted workers to replace heavy mud, used to keep the well's pressure down, with lighter seawater to help speed a process that was costing an estimated $750,000 a day and was already running five weeks late, rig survivors told CNN.
BP won the argument, said Doug Brown, the rig's chief mechanic. "He basically said, 'Well, this is how it's gonna be.' "

Maybe if we had some drillers on the forum they could explain the problems of using seawater rather than heavy mud and how much time could be saved thusly.

A Smoking Gun in BP's Deep Horizon Mess

Thom's nationally syndicated radio show. 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 personnel 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 personnel to shore.

6 hours later, the platform explodes."

I work for Schlumberger and though the terminology in the articles is off a bit it supports the article EG quoted. I don't know if this is true but it does fit SLB safety standards.
