I work with hydraulics on a daily basis, and have only a rudimentary idea of the pressures they are working with at this depth. I read that the oil is coming out of the pipe at 30,000 psi. A ultra high pressure situation on a forklift, or tractor hydraulics is 3,000 psi. Normal hydraulic working conditions are 1800 or so psi. I cannot get a grip mentally on what it will take to plug a leak at 30,000.
This is an entire new scenario to most of us who work in the "normal" world of pressures.
They have tried the "dome", and have tried plugging the shaft with drilling mud and concrete. What next? The best people to know are those that work with this on a daily basis, namely BP. I'm of the opinion that if this could be plugged easily, BP would have done so quickly, as they have nothing to lose and everything to gain by this leak stopping as quickly as possible.
The financial ramifications are astounding long term. If this continues, it will most likely end BP.
