    摘要: 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 multi-section motor, an isolation device, and a pump. The method further includes supplying a power signal from the surface to the motor via the cable and sequentially operating each section of the motor to mimic a multi-phase motor, thereby driving the pump and lowering a liquid level in the tubular string to a level proximate the reservoir.

    摘要: A technique is provided for processing well fluid downhole. The technique utilizes equipment for separating a well fluid downhole into a water component and an oil component. The separation of water and oil can be controlled by selecting an appropriately sized flow restrictor for use in limiting the flow of one or both of the water and the oil. Additionally, a sensor system is used to monitor a well characteristic that enables adjustment of the downhole fluid processing based on well characteristic data from the sensor system.

    摘要: 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.
