Could you rephrase as it sounds like they ran out of the area, the way you wrote it.

Red,

The only way I can see damage occurring downhole is from the very high pressures encountered. They estimated it required 18,500psi downhole to blow the 10,000psi rated BOP stack at the surface, which is a *@#! of a lot of pressure.
It seems to me that the only place damage can occur is right at the base (17,600'), where gas may have been able to force it's way past the cement at the casing shoe (I think the last casing was 9 5/8").
This seems unlikely, since they spent 5 weeks dealing with this casing, through October, and evaluation of the original cement job showed that it was inadequate, so they did a cement squeeze. Subsequent pressure testing showed the cement job to be good, so all the right steps were taken.

I agree with your thought, that they are just covering all the possibilities. They should have no trouble nippling up a new BOP stack.
