Abstract
A side pocket mandrel for use within a gas lift system is configured to permit the exchange of valve pockets. The side pocket mandrel has a central body, a receiver that is laterally offset from the central body, and a valve pocket that is removably secured to the receiver. The valve pocket can be configured for a threaded connection with the receiver to permit the facilitated exchange of modular valve pockets at the receiver. Gas from the valve pocket can be carried to the central body of the side pocket mandrel through one or more external gas lines or one or more internal gas injection passages.
