Abstract
A dual barrier side pocket mandrel with gauge includes a gas lift barrier valve mandrel with permanent sensors and at least two pockets for accepting gas lift barrier valves, wherein the pockets are connected via a port. The mandrel also includes a production conduit along a central longitudinal axis. The mandrel is encompassed by a casing on the inside of a well. The permanent sensors can monitor a pressure or a temperature in the casing, production conduit, and port to determine the status of the individual gas lift barrier valves.
