The final cut..... Deep water Horizon

[Martin Riddle]

This is interesting, They cut the riser with a large shear, now they
are cutting the riser at the top of the BOP.

Anyone betting lots of oil will gush out?

Is it just me being cynical, or is someone paid to sit there and twiddle the
ROV joystick 24/7 to make it look like they are doing something?

Just nuke it I recon. Can't possibly do any worse.

Yup. If they unlucky they could almost double the flow rate.

I just hope they have some convincing way of attaching the new
contraption that is supposed to take the oil away afterwards. Oh look it
has filled with ice and dropped off will not play well.

I want to see what instructions the production manager of the rig gave
to the operating team and when they knew the BOP was no longer failsafe.

Hello,

they could not replace the bad BOP by another good BOP, they only could
mount another BOP on top of the existing BOP.

The oil pressure is coming from 1 mile of water (2000 psi) and 3 miles
of rock (10,000 psi). 7,000 is too low.

But 12,000 psi is the pressure a 4 miles below the sea surface. You
still have a 10,000 column of oil. The question is how much pressure is
forcing the oil up? Its greater than 2000 psi at the well head for
sure.

It looks like fairly well cracked oil, not Mazola but it's been under
pressure and heat for quite some time. Which makes it easier to refine.

Calculating rock (or any solid) contribution to pressure like it is a
fluid is rather unlikely to be correct. Solids transmit forces in all
directions but differently than fluids. Some of the rock might be in
tension which works out very differently for fluids, solids also support
shear (lateral) strain well which fluids do not do worth a damn.
