  • Publication number: 20070181312
    Abstract: Gas lift valve designs and gas lift systems are described that feature a positive closure mechanism that is highly resistant to significant wear or damage that would result in fluid leakage. A pivotable flapper member is incorporated into a gas lift valve and used as a flow control mechanism. The flapper member provides a positive barrier to fluid flow from the production tubing to the annulus, even after substantial wear or damage.
