A couple of questions to anyone with expertise.
1) What material or phenomena is forcing the crude oil
out of the underwater geological layers?
2) Is it the overlaying seawater pressure
that's primarily responsible for such pressure behind the oil gusher?
3) Or is it pressurized methane that's driving the oil out of the sea bottom?
4) When the crude oil eventually drains out of those geological layers,
what happens next, geologically? (nature abhores a vacuum)
