Wow I just realized, maybe they can't attach a shut off valve to the blowout preventer flange because if they completely seal the well at the top, if the concrete that forms the bond with the sea floor is compromised (blame Haliburton) the pressures coming out of the well would blow the entire set up off the floor resulting in a widening well head making it even more difficult to seal shut. That's why they had better hope they connect with the relief wells.
I don't understand what caused fractures 7 miles away with oil leaking out of them. Is the author saying the Deepwater Horizon mishap caused these distant fractures? How does that happen? Maybe it has something to do with the Haiti earthquake? Maybe that cracked the concrete well plugs down inside the well shaft and caused them to fail? I have heard there was a rig leaking something like 7-12 miles away to the west of this site but nothing of fractures scattered around that area.
I watched the Sixty Minutes interview where the guy said the annular valve seal was damaged by being closed and having about twelve feet of the drill shaft pulled upwards chewing up the rubber seal. Then at some point the two concrete plugs failed. Anyway who can believe any one thing at this point? What does it matter? We have to stop the oil.
And that article talks about the nuke option being our last resort to stop the oil but what about all the other leaks in the area? Are they all going to be stopped with one nuke or does each fracture need a nuke? The reasoning seems to imply there are multiple fractures within a 7 mile radius but if we seal the one well it will solve the problem. I'd need to know more details.
