Oil leak, sorry, hydrocarbon stream stopped in the gulf - Trouble - 07-15-2010
Just heard on the radio so no cite. Worried about it holding due to pressure, but right it is holding.

part of a pressure test. CNN showed the dramatic picture of nothing leaking into the gulf through the pipe.
The risk factor now is blowing out the well below the cap, so they are being careful about that.

is the new Jimmy-Hat working?

I'm hoping this new cap/pressure integrity tester doesn't pop the well casing like a big giant zit.

Yeah, it'll blow below the sea bed and then nothing will be possible to stop it.

They said again today that it's pushing around 8-9000psi, that's about 3x what standard hydraulic system
on a basic piece of machinery would run and that the pressure on the seafloor is making it go so high.
Doesn't that mean that as we take oil out the seafloor should sink downward if that's what's causing these
extreme pressures. I'm surprised they are able to control, having taken hydraulics in college I know that's
a lot pressure to try and control. I've seen hydraulic motors and control valves that have exploded from
being pushed to 5-6000psi.

I get it!

High pressures just require a little beefier engineering. One process plant I ran operated at 1,800 psi and it was built about 1936. IIRC, the plant that Golfer ran was about 3,000 psi. CNC water jet cutting runs 40,000 psi and up.
The high pressure is one reason that their current class of Blow Out Preventer only works 45% of the time. It worries me that so much of the equipment used this region is pretty similar. They need a little more experience and better design.

There's an entire engineering field (reservoir engineering) that studies the properties of petroleum reservoirs, including their behaviour when fluids are withdrawn from (and pumped back into) them. The simplified answer is yes, in general the seafloor or land surface sinks when we withdraw large quantities of oil, often significantly. In many cases where this might be a problem water is pumped into the reservoir simultaneously with hydrocarbon withdrawal.
