Compact cable suspended pumping system for dewatering gas wells |
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. |
