redstick.....you are saying the gas came up on the backside of the casing? That was my thought as well. If you have the time give your best scenario of what you think happened to cause the explosion.

Yes. They likely had channeling in their cement job which was only to the bottom of their last casing string. They had no cement overlap inside of the previous string. I think it's likely gas was channeling behind the long string and building up pressure against the upper seals at the wellhead. Once the upper seals gave way it probably thrust the top of the 9 5/8 inch casing up into the BOP stack. That's why they had so little time to react on the Horizon. The gas would have shot up the riser like a rocket and the pressure would have been far to much for the annular preventer to handle when the driller closed it. When the explosion tripped the dead man I think the shear rams activated but they aren't able to shear through the top of the 9 5/8 casing string jammed up in the BOP.

Ok so this is one of my thoughts as well. the gas came up and was brought the gas into the intake of the diesel engines which would explain why some accounts say one of the engines was revving wildly, this then caused the first explosion.
What do ya think?

I'm watching Skandi ROV I. I see the yellow leveler. I see a blue hose that is pumping methanol. I see an oil dispersant sprayer.
Is the top hat in that oil plume? Is it locked down and sealed on the cut riser section? Is there a valve above the tophat that is pushing the flow back out of the grommet?

yes, part of it, the rest is below

not sure, it's on the cut riser, but not sure if it is sealed and clamped on

not sure

Somebody please explain why the pipe appears to look exploded on Enterprise ROV 2. Appears to be leaking heavily. Haven't seen that shot before.
ETA: Looks like it could be part of the top hat but it's just covered in so much oil. Sorry, just getting back to this and need a quick update.

Redstick - would it be possible for them to use the two inlet/outlets they used for the mudd pumping into the well to suck or pump some oil out to help relieve some pressure to the top?

Anyone know what that is that the q4000 ROV1 is monitoring ?
Posted on 6/3/10 at 10:32 pm to LSU Fan SLU Grad
enterprise rov 2 is o the opposite side and a little above skandi 2, I think that is why it looks that way, my guess would also be that it isn't seated right

Government staffer here and we're trying to find out what the hell is currently going on.. BP isnt saying a damn thing, and all their press reps have called it a night. It's a shame that CNN is the best resource we've got currently for information on the situation.
Anyone in UCG or involved with the Coast Guard?

Im assuming the riser is either not connected to the containment cap or the suction has not started. The flow has not decreased one iota.

not likely....I have had some old timers tell me that diesel engines will "run away" when gas is present, but my company frequently runs diesel engines in that environment and I have never seen it happen in over 20 years....lots of engines died out, but none have run away...

Agree. I think it's in position, but they haven't begun doing anything w/ it yet.

Just a theory me and my dad were talking about. He has is a veteran on land rigs with a little experience offshore. I worked on his rigs in college during summers, holidays and weekends so i have a little knowledge of what is going on. When i say i have a little knowledge i mean it.........lots of you guys seem very knowledgeable about the situation.
