Abstract (en)
[origin: EP2863006A2] A method for performing downhole gas lift operations includes coupling a gas lift valve (140) to a tubing (120), wherein the gas lift valve includes an actuator (240), a flow control device (250) disposed in the actuator, and a closure member (230) that is initially in an open position; injecting a gas downhole and exterior to the tubing; urging the gas to enter the tubing via the gas lift valve; and creating a sufficient pressure differential across the gas lift valve to move the actuator, thereby causing the closure member to close the gas lift valve.
