1. A system for producing hydrocarbon fluids from a subsea formation, comprising:
- at least one producing well penetrating said formation for producing hydrocarbon fluids;
at least one dummy well hydraulically connected to said at least one producing well;
at least one pump disposed in said at least one dummy well, said at least one pump taking suction flow from said at least one dummy well and imparting flow energy to a discharge flow of said hydrocarbon fluids; and
a manifold system for routing flow to the at least one dummy well.

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