Abstract
A gas lift system for use in marginal well and small diameter production tubing is disclosed. The system uses compressed natural (produced) gas to lift formation fluids thereby enhancing produced gas. Incorporated in the system is a plurality of differential pressure control valves which provide the required lift capability for a standard jet pump, located at the bottom of the wellbore, to continue to lift produced fluids. The methods of use are described.
