94 and the fluid flows through flow chambers 92 until it is discharged through an impeller outlet 96 to diffuser 62 with mixed flow impellers the fluid typically is drawn from a lower location through inlet 94 and moved upwardly and outwardly for discharge at a higher location the fluid is pumped through consecutive impellers and diffusers as it moves through the plurality of stages 58 for discharge through connector 50 and tubing 44 see fig4 viscosity handler 24 may be deployed in a variety of environments and in combination with other components that are used in downhole applications or with electric submersible pumping systems additionally component configurations can be designed to supplement the transfer of energy from the viscosity handler 24 to the fluid being produced by production pump 12 as illustrated in fig7 submersible motor 30 may be located above perforations 40 such that the fluid flows past submersible motor 30 before being drawn into viscosity handler 24 the heat of the motor assists in lowering the viscosity of the fluid flowing past alternatively or in addition to this arrangement of submersible motor 30 a supplemental heater 98 may be located within the wellbore as illustrated in fig7 an exemplary supplemental heater 98 is a resistive type heater powered via a power cable such as power cable 56 or a separate power cable deployed downhole such a supplemental heater 98 may be positioned independently within wellbore 36 or it may be combined with electric submersible pumping system 28 to heat fluid as it flows past and external to the heater supplemental heater 98 also may be designed for deployment downstream of fluid intake 52 such that fluid is drawn through the center of the heater prior to or after entering viscosity handler 24 in addition to.
