Provisional Patent Application Filed

This invention reports an optimization to the principle of gas lift to increase oil production using a gas lift system. Gas lift is an artificial lift that uses external sources of high-pressure gas to supplement formation gas in order to lift the well fluid. This invention reports the optimum design as reducing the amount of stem travel required to generate flow area equivalent to the port area. Further, the reported design addresses the issue of bellows efficiency and can circumvent the lack of it in current systems' gas lift valve performance. 

Reference Number: D-1308 

Market Applications:

  • Oil and Gas Industry (Artificial Lift Systems) 

Features, Benefits & Advantages:

  • Increase to gas throughput of the valve
  • Increase of oil production for artificial wells using a gas lift system 

Intellectual Property: A U.S. Provisional Application was filed in December of 2016. 

Development Stage: This invention has been utilized in the field and work is continuing to make it even more applicable to all gas lift valve systems.
