A relief well is drilled in an attempt to relieve pressure by intersecting the damaged well. The pressure is too high to attempt this technique. The only solution with available technology is the one that will be used. They wont risk tapping into this again and trying to tame it, what youre talking about is believing BP at face value. The injection of material into the well below the BOP to plug it up would require overcoming the pressure of the well, and there is no way to create the pressure neccessary, so that was BS.
Theyre going to have to do exactly what I said in order to stop this blowout. Tapping into the damaged well is inviting an even more spectacular disaster.
