Abstract:
A system for pumping a wellbore fluid while reducing detrimental effects of solids dispersed in the wellbore fluid, comprising:a solids separator that separates 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 axially aligned with and coupled to the submersible pump to provide power thereto, wherein a drive shaft extends from the submersible motor to the submersible pump and the solids separator is disposed at a radially displaced location with respect to the submersible motor and the submersible pump, further wherein the drive shaft does not extend through the solids separator.
