Abstract
An electrical submersible pump system include an electric submersible pump coupled to a lower end of a production conduit extending into a wellbore, the production conduit in fluid communication with a discharge of the electric submersible pump and with a well conduit extending to the surface. A bypass conduit is nested inside the production conduit and is in fluid communication with the discharge. The check valve is opened when flow is established in the annular space and is otherwise closed. The bypass conduit extends for a selected distance above the discharge. The bypass conduit has a plurality of selected diameter apertures through a wall of the bypass conduit to enable flow into the annular space.
