BP Static Kill Update – The Static kill procedure which started August 3, 2010 is doing very well as planned. The procedure which involves pumping oil back into the well and then sealing it off with cement seems to be working and the well is not leaking any more oil until now.
Mud and cement had been pumped to the oil well in order to finally shut it off. After the initial pumping of mud and cement it was reopened and then checked to see the integrity of the procedure. After that more mud and cement was pumped until it will finally be safe and no oil will be able to escape and leak again.
After the cementing the next process for the BP Static Kill is for the well to undergo pressure tests to validate the seal will hold, then the well can be considered effectively sealed, even though it is going to take another two weeks (one week to intersect, check and cement the annulus, then another week to do the same for the production casing) before the fleet of ships can disperse.
The process of the BP Static Kill and pumping the cement into the Deepwater well started last Thursday at 9:15 am CDT and stopped the operation at 14:15 CDT. After that a period of about 24-36 hours is needed before the testing resumes in order for the cement to harden.
After testing the integrity of the static kill on the Deepwater well, the relief well will start to drill forward into the annulus. The process of going down, intersecting and then cementing the annulus, and then doing the same for the production casing is apparently further confirmation that the well flowed up the production casing, which implies a shoe failure, rather than the annular failure which was the predominant theory of failure earlier in the summer.
The entire procedure assures that the cement and mud should result in bring the pressure in the well to zero for it to be declared a success and then after that the relief well will be in full operation.
Besides these data we have also gathered the most updated estimate on the oil which flowed out from the BP Oil spill courtesy of The Oil Drum website.
Update, Monday Evening (August 2, 2010), 7:00 PM EDT New flow rate estimates were released today by the same US scientific teams who released the earlier estimates. Their findings:
- 53,000 barrels a day were leaking, just prior to capping.
- The amount of leaking had declined, prior to closure, as a result of depletion.
- Initially, 62,000 barrels a day were leaking from the well.
- Approximately 4.9 million barrels of oil have been released from the well; of this containment activities captured 800,000 barrels of oil.
- The uncertainty in these estimates is plus or minus 10 percent.
