  •  This part doesn't involve cement (13+ / 0-)

    It's about the mud.

    If injecting the mud works to stop the flow - the Top Kill - then later the well will be capped with cement.

      I was more or less trying to get a time frame for the cement stuff.

      Like, if the mud stuff work(s|ed), how long does it need to work for the cement portion to even have chance at working.

      It seems as though the window is fairly small and the issue of time doesn't seem to be the determining issue.

      It seems that the bigger question is whether we even get to the point where the cement can be implemented.  Then if that happens, once the cement is in place, can the rest of the rig maintain the pressure.

      Does this stuff sound right?

        my understanding of the situation is that they need to get enough mud into the hole that its weight can stop the flow of the oil.  At that point you can pump in cement without the pressure blasting the cement out.  The mud we are watching blowing out now could mean either 1) they are pushing mud in faster than it can sink into the hole, or 2) the oil pressure is still much greater than the mud's weight.  Obviously we want to work from situation #2 toward situation #1.

        Anyone out there know enough to confirm this interpretation?
