Abstract:
A plunger lift system that uses a linear induction motor instead of gas or fluid pressure to lift the plunger. Electrical voltage is applied to electromagnets installed along the tubing of a wellbore that will induce magnets contained within a special plunger that is introduced inside the tubing to move it and allow it to lift liquids with a piston-like action. The electromotive force may be adjusted by varying the applied voltage as needed to lift the column of liquid from the wellbore or the current reversed to accelerate and optimize plunger descent.
