Electric gas lift valve

Abstract

Electric gas lift valves and systems including a gas lift valve. The gas lift valve may comprise an integrated back check valve and choke valve. The integrated back check valve and choke valve may be retrievable. The gas lift valve may comprise an actuator. The gas lift valve may comprise a fail-closed mechanism comprising a power spring and an electro-magnet that powers a disconnect clutch. The fail-closed mechanism may be configured to close the choke valve in response to a loss of a functionality of the actuator. The gas lift valve may comprise a needle valve that is configured to place the choke valve to vary in an inflow rate. The choke valve may be modular.
