I looked because I was curious,but couldn't find a figure. I was wondering if the resistance of atmospheric pressure would lessen the pressure at the exit point of the well head. In other words, would it be less than at the surface, say in an desert oil field.
I was listening to the engineering prof who was testifying before Congress. He mentioned the diameter of the hole and the flow rate, so you could compute the velocity and guess the pressure from that if you are really interested. That professor must have calculated the pressure somewhere.

My first response is that there's no doubt that the pressure exerted by the water at that depth would press upon the oil flow.
So with 2161 PSI already present, would a new BOP actually require 2500PSI capacity [if that's the actual wellhead pressure]? I realize that it's always best to have a large measure of safety/redundancy.
they dont seem to be talking about doing this anymore, I assume because they dont know the exact nature of the failure, so they don't know what situation they would be faced with if they cut the current BOP off. If the pressure is anything close the the reservoir pressure there is no way they are going to get a new BOP in place...the result of trying would be to make the flow rate many multiples of what it is now.
