Suppose they had determined that the cement was faulty (either by running the extra test or from deciding they didn't like the previous results), what would they do about it?

Is there a method for fixing the cement? Or do they have to drill it out and do it over? Or do they just plug the hole and dig an all new one?

How long would all that take? Is it common?

It is my understanding that the cement is used to form a jacket/lining around the inside of the hole so that it can be used to extract the oil/gas. Why not just leave the pipe they used to drill the hole in place? Is the pipe that expensive?

Okay... that's six replies and nothing but "bemusement" post. What am I missing? I thought I was asking a legitimate question?

the cement truck at the bottom of the gulf was rutting up the yard and they didn't want to back another truck up and make more ruts.

Good luck finding an answer. My entire family works for drilling companies and has for generations, but if you don't work in that field it is like explaining calculus to a 4 year old. As you can tell from the replies so far, they can also be dicks when asked to explain it to a layman.

You need some time on a rig man.

I think it's stupid to put cement in the same hole you are trying to get oil out of. No wonder you have wells blowing out every other day.

It is incredibly difficult to explain without seeing it in some fashion. My family talks to me like I'm an idiot, but when they sat down and drew it for me, it was simple to understand.

I am an accountant and can understand this. It sure isn't rocket science.

Agreed, but the lingo used offshore is not exactly commonplace, and it is difficult to put it all together while reading it or hearing someone explain it. Risers, casing, mud, shoe, BOP, kick, etc. don't really jive with most folks. It is one of those things most people need to see to understand how it works.
