Abstract

A submersible pumping system for producing a fluid from a wellbore through production tubing to a wellhead includes a pump assembly that has at least one pump, a motor that drives the at least one pump, and a recirculation module. The recirculation module includes a recirculation mandrel positioned within the production tubing and a recirculation line extending from the recirculation valve to the pump assembly. The recirculation module delivers a volume of priming fluid from the production tubing to the pump assembly. In some embodiments, the recirculation module further includes a recirculation valve, which can be positioned in an offset relationship from the recirculation mandrel.
