Abstract:
A gas lift system may be installed within a well to allow gas lift operations where gas may be injected into the annular area of the well while producing fluids through the interior of the production tubular or upon demand may be reversed so that gas may be injected into the interior of the production tubular while producing fluids to the annular region of the well. In order to allow bidirectional production on demand two types of gas lift mandrels are installed as part of the production tubular. Both types of gas lift mandrels are configured such that gas lift valves are mounted to the exterior of the mandrels.

Claim (Index 1):
A device for lifting fluid from a well comprising:\n a production tubular having a first gas lift mandrel and a second gas lift mandrel; the first gas lift mandrel having a first check valve mounted on an exterior of the first gas lift mandrel oriented to allow gas or fluid to flow from the exterior of the first gas lift mandrel to an interior of the first gas lift mandrel; the second gas lift mandrel having an external gas tight chamber and a second check valve within the external gas tight chamber oriented to allow gas or fluid to flow from an interior of the second gas lift mandrel an exterior of the second gas lift mandrel.
