re: Oil field people: How much will getting the annulars closed help?

they never really knew how much was leaking in the first place. they just had to throw some numbers out there. hence the reason the numbers were so way off.
some were saying 5000
some said 20000
some said 5 x that amount
no way to calculate.
Actually BP should have a pretty good handle on how much the well was flowing. They would logged the well at that point and should be able to guage what the well would flow within a reasonable range. I think they threw out some worst case estimates of 20k per day just to CYA a little.

So if they clamped off one of the leaks... and if they clamp off other leaks, wouldn't that eventually build up pressure from the inside of the well, and wouldn't they just blow again?

once the valves are closed, this will give the other rig ample time to complete the relief well.
it will hold and nothing will blow. hopefully.
ever kinked your water hose?

With the annular closed it may be possible to run in a packoff into the exposed drill pipe and shut the flow. If done, worst case is they lose all integrity at the subsea wellhead, because i have a feeling the leak path is in the annulus behind the production casing via a failed seal assembly. Best case is the frac point at the previous shoe is reached and you are left with an underground blowout, which still must be killed with a relief well.

Yeah pressure would build. Dont know if it would blow again but yeah thats definitely not a permanent solution. Just a temporary fix until they can plug this well with the relief well.

Yep, while the faucet was on full blast, and it popped a seam like a fat man splitting his pants. But that's just happened once, and it was my neighbor's cheap hose.
Good news though... I hope this works. I hate everyone is having to go through this- on both sides.

Piston shoves up on that black rubber doughnut (packing unit) and squeezes the pipe to form an effective seal.

I can't believe that I've read enough about this over the past several days to actually have an idea of what this means..

Geezus BP get your shite together!!

i knew it was too good to be true. the idea that the annular rubber, after that much unrestricted flow, would still be in good enough shape to hold pressure seemed a bit too far fetched. but i was hopeful.

shite, shite and frick. The BP bastards need to get their shite together and at least control what their execs are spouting. frick the spin just give an honest assessment for better or worse.
