Vertical Annular Separation and Pumping System With Outer Annulus Liquid Discharge Arrangement

摘要

A system for producing hydrocarbon fluids from a subsea formation comprises at least one producing well (1) penetrating the formation (2) for producing hydrocarbon fluids. At least one dummy well (7) is hydraulically connected to the at least one producing well (1) for routing the hydrocarbon fluids from the producing well to the dummy well. At least one pump (8) is disposed in the at least one dummy well. The pump takes suction flow from the dummy well (7) and boosts the flow energy of the discharge flow of hydrocarbon fluids.
