Abstract
Embodiments of the present invention generally relate to a cable suspended pumping system. In one embodiment, a method of producing fluid from a reservoir includes deploying a pumping system into a wellbore to a location proximate the reservoir using a cable. The pump assembly includes a motor, an isolation device, a pump, and a power conversion module (PCM). The method further includes setting the isolation device, thereby rotationally fixing the pumping system to a tubular string disposed in the wellbore and isolating an inlet of the pump from an outlet of the pump; supplying a DC power signal from the surface to the PCM via the cable; and supplying a second power signal to the motor, thereby operating the pump and pumping reservoir fluid from the reservoir to the surface.
