| description | Embodiments of the present invention generally relate to an electric submersible pumping system (1) for dewatering gas wells. In one embodiment, a method of unloading liquid from a reservoir includes deploying a pumping system into a wellbore to a location proximate the reservoir using a cable. The pumping system includes a motor (50), an isolation device (60), and a pump (65). The method further includes setting the isolation device, thereby rotationally fixing the pumping system to a tubular string (10t ) disposed in the wellbore and isolating an inlet (65i) of the pump from an outlet (65o) of the pump; supplying a power signal from the surface to the motor via the cable, thereby operating the pump and lowering a liquid level in the tubular string to a level proximate the reservoir; unsetting the isolation device,- and removing the pump assembly from the wellbore using the cable |
