Missing data causing rig reconstruction mystery

While some data were being transmitted to shore for safekeeping right up until the April 20 blast, officials from Transocean, the rig owner, told Congress that the last seven hours of its data are missing and that all written logs were lost in the explosion.

Halliburton & the Oil Spill

I know there are some people who have professed that Haliburton Purchased Boots & Coots for ulterior motives. The Wall Street Journal reported online that Haliburton was being investigated for the Rig explosion, whatever that means.

Of course this story goes deeper....

However, when Transocean claims that they have lost the data of 7 hours before the explosion. All seems a bit more curious.

"I can just tell you that the Halliburton hands were scratching their heads," said Buzbee, whose clients include one of the Halliburton crew members responsible for cementing the well to prepare for moving the drilling rig to another site.

"The facts are as they are," he said. "The rig is $500,000 a day. There are bonuses for finishing early."

More investigation to come...

Consider these 2 facts:

1) No one in charge knows who gave "the order" to spray water on the rig for days on end until it sank. Experts believe it was the spraying of water that sank the rig.

2) Transocean is using an law from 1851 that limits their liability of the disaster to only what the value of the SUNKEN vessel is worth. That value is $27 million. If it had not sunk, it was worth over $500 million. Their insurance pays them $580 million. After they pay the $27million, they will have a profit of $533 million.

Now read those 2 facts AGAIN. Are we getting the picture yet? Combine that with this "missing data" story you posted, and the picture becomes crystal clear. The destruction and subsequent sinking of the rig was a planned operation by Transocean to make 3 years profit in 1 quarter.

I don't think this was a planed disaster.

This disaster was do to poor calculation and judgment form the engineers aboard the rig.

The mistake these engineers made was that they took away one of the barriers that must be in place. A well always must have at least two separate barriers at all times. In this case the tested cement plug being one barrier, and the mud fluid as the second barrier. And than you have the BOP as the third. But the primary barrier is the mud, because the mud is always observed by the derrickman at the shakers/pits. This is where they observe the return rate of the mud. This is where they can observe loss or gain of fluid.

When they displaced the casing from mud to sea water, by pumping sea water down through the drill pipe. The hydrostatic pressure from the sea water is less than the hydrostatic pressure form the mud. This allowed the gas to migrate through the cement plug between the drill pipe and casing. And the gas migrated and settled under the closed rams on the annular preventer on the BOP. When the displacement was completed. They must open the annular preventer to be able to retract the pipe back to surface. The annular preventer is a ram that closes around pipe and seals it of. When they opened the annular preventer the gas pressure pushed all the fluids in the marine raiser up towards the drill Flore. And when the fluid was pushed out the gas will fallow.

EDIT to add:

The the Shaker is the place where the gas would first appear because that's where the mud must be circulated out from the well. Because they pump sea water down the pipe and take the return through the shakers.

They should never have opened the annular preventer on the BOP. They should have closed everything in and circulated the gas under the annular through the rig choke to the flair boom as they would have done if there was a kick.

EDIT to add: These reservoir engineers would most likely be BP employed workers. And BP do have a record of trying to cover up their own mistakes.

I have worked for BP a lot. I know this first hand. If you write a RUH on a BP employee the RUH would most likely end up in the trash. RUH'es are bad for business.
