ABSTRACT:
An auto-cycling plunger and method for lifting out condensate and fluid that accumulate and retard production in oil and gas wells. The auto-cycling plunger comprises a tube that defines an inner chamber, one or more flapper sealing rings mounted on the tube and a detachable valve member positioned at one end of the tube. During the method, the auto-cycling plunger free falls down the production tubing string with the detachable valve accelerating faster than the tube. The detachable valve hits the bottom-hole spring first, the tube follows and engages with the detachable valve thereby creating a seal. The liquid collects above auto-cycling plunger and the plunger moves up the production tubing as gas within the well accumulates below it and creates an upward pressure. The auto-cycling plunger repeats it's movement up and down the well without having to shut-in the well thereby continuously removing liquids without stopping production.
