Abstract
A side pocket mandrel for use in a gas lift system is configured to improve the recovery of petroleum fluids from a well, where the gas lift system is surrounded by an annular space within the well. The side pocket mandrel includes a central bore extending through the side pocket mandrel, a side pocket tube laterally offset from the central bore, a port that extends from the side pocket tube to the annular space, and a single actuation valve installed on the port. The single actuation valve prevents the passage of the petroleum fluids from the annular space into the side pocket tube until a high threshold pressure in the annular space is reached and then the pressure in the annular space is reduced so to a low threshold pressure.
