Abstract
A technique enables independent lifting of fluids in a well. The technique utilizes an electric submersible pumping system which is disposed in a wellbore and encapsulated by an encapsulating structure. The encapsulating structure has an opening through which well fluid is drawn to an intake of the electric submersible pumping system. A dual path structure is positioned in cooperation with the electric submersible pumping system and the encapsulating structure to create independent flow paths for flow of a gas component and a remaining liquid component of the well fluid. The independent flow paths also are arranged to prevent contact between the well fluid components and a surrounding wellbore wall.
