Abstract

An artificial lift system for use in a well bore including at least one chamber (14) having an inlet and an outlet, a power gas string (16) in valved communication with the chamber (14), a liquid string (18) in valved communication with the outlet of the chamber (14), a vent (20) in valved communication with the chamber (14) and in valved communication with the liquid string (18) at a location above the chamber (14), a compressor (22) connected to the power gas string (16) and adapted to pass a pressurized gas into the power gas string (16), and a valve (24) connected to the power gas string (16) and to the chamber (14) the adapted to selectively allow the pressurized gas to enter the chamber (14) so as to cause a liquid in the chamber (14) to pass through the outlet of the chamber (14) and into the liquid string (18). The vent (20) has a check valve (29) connected to the liquid string (18) and adapted to pass a portion of the vented gas into the liquid string (18). The liquid extends continuously as an ungasified liquid along the liquid string from the outlet to the check valve (29) between the vent (20) and the liquid string (18).
