DOWNHOLE FLUID TRANSPORT PLUNGER WITH THRUSTER

摘要

A method for lifting fluids within a subterranean well includes lowering an elongated plunger to a lower region of a bore of the subterranean well. The plunger includes a motor assembly operably connected to a propeller. A seal can be created between the plunger and an inner surface of the bore of the subterranean well. A thruster, such as motor assembly connected, to a propeller, generates thrust to lift the plunger to a plunger retainer located proximate to a wellhead of the subterranean well.
