Gulf Oil Leak Plugged?

RobHart writes "The LA Times is reporting that the Gulf oil leak appears to have been plugged by the 'top kill.' 'Thad Allen, who is coordinating the government response, says the well still has low pressure, but cement will be used to cap the well permanently as soon as the pressure hits zero.'"

      "Real" engineering is not like your geek job. When the rig blew, people died, and others needed immediate rescue to survive - and BP was there for that. There were several in-place preventive measures as part of the disaster prevention plan, but they failed - largely due to poor management culture endemic to BP, where warnings from the guys on the rig were ignored. BP certainly deserves blame for that. The same cultural problem led to the gas pipeline blowout, if you remember that.

      Efforts to plug the well started immediately, and as there's no way to know what will work, several parallel efforts were all started. Lots of silly /.ers who seem to think this is like fixing a down server are asking questions like "why didn't they drill the relief well first, since that's the only permanent fix". They did start the effort to drill the relief well immediately; it will be done in August IIRC. This isn't a down server - real engineering work is required here, real heavy equipment must be designed, built, shipped to a port, loaded, and shipped out to the middle of the gulf at 15 knots.

      The "top kill" effort was started as soon as the problem was understood - it just takes time to do stuff like this.

      For a full plug & abandon procedure, they'd not only have to pour some cement, but actually go down the bore again, pull the string, place multiple seals and cement those, so as to protect from further blowouts. That might not be possible at all here, so some basic cementing might have to suffice until the relief well is done. While this is looking good at the moment, we have just reached a temporary solution, at the time being just a temporary seal with the mud pumps holding against the reservoir pressure. We have to hope that the engineers manage to transform that into a static solution. I am pretty sure that the relief wells have to be completed - I don't see how a long term solution could be achieved without getting down to the bottom of the well otherwise. All this hugely depends on the condition of the bore - is the casing intact? Obstructions? Partial collapse?
