Abstract
A side pocket mandrel is configured for use within a gas lift system deployed in a well that has an annular space surrounding the gas lift system. The side pocket mandrel includes a central body that includes a central bore, a gas lift valve pocket, and a gas lift valve installed within the gas lift valve pocket. The side pocket mandrel may also include a motorized choke valve assembly to selectively cover some or all of an internal tubing port extending between the central bore and the gas lift valve pocket. The side pocket mandrel may also include an automatic closing valve assembly configured to automatically close the gas lift valve port when the gas lift valve is removed from the side pocket mandrel.
