Sailplane,
"we could have a ‘dead-end down' pocket of trapped (perched) water sitting close below the 7Z well – close enough for that pocket to undergo, in effect, localized conning"
Possibly, but we won't know until well 7z is run on it's own for a long period of time. And trying to experiment with this would be a huge risk.
"The FPSO's Produced water handling is shown as an impressive 20,000bpd, even so, it would obviously be really nice for us all if the perched water pockets showed signs of emptying some time pretty soon."
I don't think the water pockets will empty soon. Water is only drawn through a differential in pressure, in equilibrium.
Am i right in saying - The "perched water pockets" will empty as the pressure drop between these pockets increases. Or in other words, a lot of barrels need to be produced, such that the pressure within the wells decrease to the point where all water is drawn from the specified "higher water pocket"?
