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."

Harris told Upstream BP released the Schlumberger crew on the morning of 20 April. They left the rig, in Mississippi Canyon Block 252, on board a regularly scheduled helicopter transfer at 11am, local time, that day.

This sounds illinformed to people in the drilling industry. It almost sounds like some sort of marketing ploy by SLB. Firstly, a CBL (cement bonding log) would not have been run on this type of job - the CBL needs to run through / past the cementation (on the casing exterior) - not able to do so when an internal cement plug has been set (solid throughbore). Secondly, Schlumberger wireline crews have no knowledge of wellcontrol - it is not an operation on their radar. Thus, they have no IWCF well control exams/certification and is thus unlikely that they would be giving instructions out on a topic that they are complete laymen. Thirdly, the means of killing the well is wrong - you would shut in the well first, then kill it in a controlled manner with kill weight fluid (not 'dumping'). Unfortunately this whole issue has snowballed drastically because the people to deal with this issue have been pushed out of the way by office people, scientists & others who have no knowledge of the equipment and op's - this goes for the scaremongerers & the idiotic engineers at BP.

Most SLB wireline crews have at least 1 person well versed in well control. They may not have a certificate but due to vast experience in field they know whats going on. They wireline crew wouldn't be giving directions but they would certainly be able to say we don't like this and want out of here. There wasn't a cement plug set so a CBL would have been appropriate and feasable. I don't know what kind of marketing ploy SLB might have been attempting. Looks like a smart crew made a wise decision to me. As for kill weight fluid the well was drilled with 14.2ppg mud, 30,000 plus barrels of 16.4ppg mud was pumped attempting to kill the well. Apparently by the time of the explosion any semblence of control was long gone.

there are alot of blogs about the mud logger taking a smoke break. he actually went to the bathroom first. they say he is to blame, i know for a fact that he convenced alot of rig members to get in the life boats instead of jumping overboard. he helped the injured in the lifeboat he was in and assisted the medic with the injured on the standby boat after everyone was on board it. he found dale the crane operator and was unable to get a response from him. he kept yelling man down several times and a few rig crew personal finally came to assist.

the bloggers should not cut down joseph, he is the best at his trade.

he has been through enough with finding a good friend of his (dale) dead on the deck. they had met earlier in the day and planned to go fishing on there next days off.

the crew members on the horizon were all like family. their family away from their home family. god bless the families that lost loved ones due to this tradgedy.

How To Bring Back A Middle Class

Thom plus logo From the 1930s to the Reagan Revolution, America grew the largest and most robust middle class in history. Along with strong unions, the main driver of that was that people earning more than about $10 million in today's money confronted a top tax rate of 91% until the 60s, and 67% until Reagan came into office.
