APPARATUS AND METHODS FOR WELL COMPLETION DESIGN TO AVOID EROSION AND HIGH FRICTION LOSS FOR POWER CABLE DEPLOYED ELECTRIC SUBMERSIBLE PUMP SYSTEMS

摘要

A method and apparatus for reducing erosion and friction losses in a wellbore using a power cabled deployed electric submersible pump (ESP). The apparatus can include an ESP disposed within production tubing, wherein a portion of the production tubing surrounding the ESP contains fluid openings that are operable to allow produced fluids to flow outward, thereby increasing the available volume for the produced fluids. The increased volume results in lower fluid velocities of the produced fluid, which advantageously reduces erosion and friction loss.
