Abstract
A side pocket mandrel for use in a gas lift system includes a primary flow bore that is linearly aligned with the primary longitudinal axis of the production tubing. The side pocket mandrel also includes valve pocket that is laterally offset from the primary flow bore, where the valve pocket includes a port that extends through the side pocket mandrel to the annular space (annulus) to place the interior of the valve pocket in fluid communication with the annulus. To prevent the unintended passage of fluids from the interior of the side pocket mandrel to the annulus through the valve pocket and port, the side pocket mandrel includes an integrated check valve within the port that permits the flow of fluids from the annuls into the side pocket mandrel, while preventing the passage of fluids from the side pocket mandrel to the annulus.
