Claim 0:
1. A downhole gas separator fluid mover assembly, comprising:
a drive shaft extending through the assembly;
a first fluid mover comprising a first centrifugal pump stage having an inlet and an outlet;
an impeller and a diffuser, of the first centrifugal pump stage, wherein the impeller is mechanically coupled to the drive shaft, wherein the impeller includes less than three flow chambers, wherein each flow chamber of the impeller includes an inlet, a flow path, and an exit, wherein the inlet of each flow chamber includes a profiled edge and an inner surface, and wherein the diffuser comprises one more flow chamber than the impeller;
a first fluid separation device located downstream of the fluid mover having an inlet and an outlet, wherein the inlet of the first fluid separation device is fluidically coupled to the outlet of the first centrifugal pump stage;
a separation chamber concentrically disposed around the drive shaft and located downstream of the first separation device, wherein an inside surface of the separation chamber and an outside surface of the drive shaft define an annulus that is fluidically coupled to the outlet of the first separation device; and
a flow path separator located downstream of the separation chamber and having an inlet fluidically coupled to the annulus, having a gas phase discharge port open to an exterior of the assembly, and having a liquid phase discharge port.
