In one example the system comprises a production tree (12, 50) that is operatively coupled to a well (14), an ESP spool (16) that is operatively coupled to the production tree and production tubing (60) that extends into the well. The system also comprises an ESP (22) positioned within an inside diameter of the production tubing (60), wherein the ESP (22) comprises an electric motor (22M) and a pump (22P), the electric motor (22M) being positioned above the pump (22P), and wherein the pump (22P) comprises a fluid inlet (22X) and a fluid outlet (22Y). The system is installed above the existing down hole safety valve, and requires no modification to the existing well's completion equipment.
