  •  Well, (5+ / 0-)

    #1 has a huge risk of blowout in some other, even less accessable chunk of hardware.

    #2 Water must be precluded from the enclosure to prevent the formation of methane hydrates, which are what clogged attempt #1. Methane hydrates are what look like snow falling on the seabed.

    Whole situation is counter-intuitive as hell.

    •  what about the hot circulated water (2+ / 0-)

      idea - aren't they planning to do that anyway - why couldn't they retry the dome with that??

      and on the first one..as a last ditch effort before relief wells...why not try??

        the introduction of heat is to keep parrafins from solidifying as they cool, which would quickly clog the plumbing.

        Umm- right now we still have some partial choke down-hole. If we constrict flow and blow out on the far side of those chokes, we increase pressure@point of release from whatever it is in the BOP to essentially formation pressure(-head), which is going to be higher. Given the stresses put on this well by now, I would say that blowout probabilty approaches one.

        This is why you fill a shaft all the way to formation with mud before you cement.

        So we would probably have a worse leak that we still couldn't fix.

        Hard to believe that things could be much worse, but there ya have it.
