There were in all probability 3 failures inside the BOP Stack. The Pipe Rams, The Blind Rams, and the Hydril failed to operate properly.

What are the chances of THAT? My dad sold for Cameron for years (long ago) and in all my years of selling drilling equipment I've never heard of them all failing.

That has had me wondering, too.

I think it may have been a question of having had the chance to close them once the blowout was apparent before the explosion.

I have been wondering why no one has attempted to hook up lines to the existing BOP and close those rams (or maybe they did), but there may be other problems.

Is there still drill pipe in the hole?

Can another stack be bolted onto the existing wellhead if the current BOP was removed? Is the casing in good enough shape to withstand the pressure? I am sure these questions have been asked elsewhere.

Pretty small. I am also puzzled by this. I keep wondering if when the cement job failed and they had about 8000 psi on the outside of the 9 5/8 casing that perhaps casing was forced up into the BOP Stack. However, the shear rams should have been able to cut that also.
