Abstract
A pumping system includes a submersible high speed electric motor operable to rotate a drive shaft; a high speed pump rotationally fixed to the drive shaft; an isolation device operable to expand into engagement with a tubular string, thereby fluidly isolating an inlet of the pump from an outlet of the pump and rotationally fixing the motor and the pump to the tubular string; and a cable having two or less conductors, a strength sufficient to support the motor, the pump, and the isolation device, and in electrical communication with the motor. A maximum outer diameter of the motor, pump, isolation device, and cable is less than or equal to two inches.
