Plunger lift mechanism
Abstract:
Method and apparatus for a plunger lift mechanism with a main channel disposed between a first and second valve. The first valve is closed by engaging a sealing member to a first seat at a proximal end of the main channel and the second valve consequently closes to with a sealing member engaging a second seat at a distal end of the main channel. An amount of pressure accumulates on a first side of the plunger lift to overcome a pressure on a second side of the plunger lift to force the plunger lift to traverse a well bore and evacuate any fluids present above the plunger lift.
