I don't understand how he would arrive at that pressure...I'll see if I can fine the thread at the Oil Drum where they talk about the pressures in the well at various points ...all less than 20,000.

There is a deep NG well in the Anadarko basin in Western Oklahoma where the down hole pressure is close to 30,000 psi.

Guess it is pressure at the BOP:

Dr bill has the degrees and experience and he said 175,000 lbs He tends to get a little testy at people who slept thru science. It has to do with attempting to secure a valve and the pressures on that valve.
