BP prepares to seal the well for good

How lengthy that program of motion will consider and how quite a lot mud is essential will depend on the oil's region in the perfectly technique.

"I don't consider we can see this as the finish-all, be-all, till we actually get the relief wells accomplished," stated retired Coast Guard Adm. But federal officials continued to say Monday that even then, they will possibly not produce the well's obituary.

Engineers can not be specific that all of the oil's upward paths have been blocked proper up till the relief effectively bores into the cut down portion of the authentic appropriately, sometime amongst Aug. In the first phase of the static kill, now scheduled for Tuesday, BP will operate an "injectivity test" to see how the appropriately holds up when item is pumped into it. 10 and 15. Thad Allen, who is overseeing the federal response tough perform.

Pressure at the leading of the perfectly will be really meticulously monitored to make optimistic it does not rise to hazardous levels.

It is feasible that the final shot of cement could be pumped into the nicely from the greatest at the stop of the static destroy technique. If that goes appropriately, a surface ship will begin gradually pumping dense mud, weighing 13.2 pounds per gallon, into the correctly. Correct right after detecting a modest leak in the capping strategy, engineers postponed proper up until eventually Tuesday the commence of a "static kill" course of action that entails pumping heavy drilling mud by indicates of the efficiently top. But it is significantly far more most likely, Allen mentioned, that the initial of two relief wells acquiring drilled will be employed to inject cement into the bottom of the genuine efficiently, smothering it sometime in the up coming week or two.

Oil could have seeped up by means of the drill pipe, its casing, the room amid the pipes and the edge of the drill hole --- an location recognized as the annulus --- or all three. Anticipated to think about numerous days to comprehensive, the procedure will fill the well with mud. If oil is in all 3 areas, it could hold considerably a lot more than two times to fill them with mud, Allen explained.
