Abstract:
A system for pumping a wellbore fluid while reducing detrimental effects of solids dispersed in the wellbore fluid, comprising:a solids separator separating a portion of solids dispersed in a wellbore fluid from the wellbore fluid, the solids separator producing a first fluid flow without the portion of solids and a second fluid flow including the portion of solids; a submersible pump that intakes the first fluid flow from the solids separator; and a submersible motor coupled to the submersible pump to provide power thereto, wherein a drive shaft extends from the submersible motor to the a bypass tube extending from the solids separator to a location on the submersible pumping system downstream of the submersible pump, whereby the second fluid flow comprising the portion of solids flows through the bypass tube to bypass the submersible pump before reinjected into a fluid discharge stream of the submersible pump; and submersible pump and the solids separator includes a hollow interior through which the drive shaft extends.
