"IF there is room in the riser (after it's cut), I never understood why they can't just shove pipe straght down the hole (like they are drilling) and start the mud pumping "top kill" but actually already be 5000 to 10000 feet in the well?
At least that way they actually have the well "shut off" subsea. It also eliminates the well pressure being put on the BOP, which I know they are also trying to avoid. This LMRP is just a way of getting it to the surface but not ceasing the flow at all. Storms could jeopardize this setup easily."
1) they would have to fish out the drill pipe already in the well.
2) The well is flowing around the 9 5/8" x 7" casing string which means they would need to either kill it from the well head or go in the hole and perforate the casing around 10,000 feet and kill it from there.

Or the casing could be collapsed (9.875") and they couldn't get down!!

This is very likely too.

Anybody getting video feed?

bp and cnn

back to the plume....oil that is, black gold, Texas tea.....

BP has plume monitoring on. Looks like leakage from the riser on the seafloor.

cnn, riser on top of bop

So why not try it. Never said it would be easy, but could it be done? If they could pump the mud that far down, it would for sure kill the flow.
So given your 2 choices, could they do it?
1. Fish the string
2. go down and perferate and start pumping mud at 10,000ft
Sure sounds logical....very hard but logical to accomplish their goal.
Might take a few more days but it would be a much better option than just flowing it to the surface in what they are trying now. IMHO

I am in the industry and would like to thank you guys and gals over here for the good discussion board and not much bs. I have always had a great deal of respect for folks from LSU and this place just makes me respect y'all more. Thanks again for letting me come by and learn and hopefully be able to contribute some.

Collapsed how far down? I'm surely no expert and aren't sure why you figure anything is collapsed somewhere.

any updates on the shears?
Posted on 6/1/10 at 2:25 pm to SD 71
Welcome to the Rant. I can honestly say to you SD71 that I wish it was over an LSU - AM game, but.....
here we are...
I will tell y'all this -- the fact that the shears did not work in cutting the pipe is amazing to me: either they have no idea what they are doing because all things are different at 5,000 or they don't possess the tools because they don't exist or they are guessing. When I am repairing my fence I don't bring nail clippers, I bring tin snips and a sazall (reciprocating saw) with a hack-saw blade...so which one is it? Why can't they get that pipe cut?

I'm not in charge but I would use what you propose as a backup plan if they aren't able to latch on with the LMRP and flow it to surface.
There's no guarantee this would even work and you are looking at allowing the well to flow for something like a week more while you do this when you can just flow it to surface and stop the oil going into the water. That would be the most desirable situation until the relief wells are in place.

By the way, your Geoduck is awesome.

If the casing is dry for some reason it will almost certainly be collapsed. Casing has to be filled while running it to prevent this from happening.

Me too , on the game and not this. I would wonder if depth and temp may have had something to do with the shear not working. Also they said they were changing the angle of the jaw.
As to the 9.875" collapsing it could be right below the well head or deeper, but myself I would not think you could get deep enough to do any good. Bullhead or kill from the bottom with relief well.

RedStick, couldn't you have enough pressure on the outside to collapse the 9.875" if you had seawater inside? I know it is usually designed for dry inside but what if you have a butt load of pressure on the backside?
