I guess that's the point though. Nobody really knows. BP seems to think there are two possibilities: Flow up the annulus and then entering the casing at the seal assembly or down the annulus and up through the float collar. I'm disappointed and frustrated that the test wasn't run but it's hard to argue against being careful.

Meanwhile oil flows unabated into the gulf . Why aren't they at least trying to capture what they can while they decide what the hell to do ?

Either situation once it is closed in at the surface the annulus will become pressured up and most likely not be able to hold 10k+ pressure. Unless there is some super high strength 16" that isn't in typical spec book, 16" will never hold that. You would just have to hope there is a good cement job on the outside of 16" to increased your integrity, but I wouldn't put money on it.

Only way 16" wouldn't be exposed is if there was trully a wet shoe, and there was a good cement job on outside of 7". All very unlikely from the information that has come out.
