US Patent 11753912 Phase changing gas-lift valves for a wellbore
Article
A gas-lift valve in a wellbore may include a valve housing and a flow restrictor. The valve housing may at least in part define a chamber for receiving an actuation fluid. The flow restrictor may have a position that is controllable by adjusting a downhole pressure to change a density of the actuation fluid in the chamber. The gas-lift valve may be positioned on production tubing in an annulus of a wellbore. Controlling the position of the flow restrictor may restrict an opening in the production tubing through which gas may flow.
