1. A side pocket mandrel for use in a gas lift system configured to improve the recovery of petroleum fluids from a well, the side pocket mandrel comprising:
an upper assembly joint;
a lower assembly joint;
a central portion between the upper assembly joint and the lower assembly joint, the central portion having a total length (LT);
a central bore extending through the side pocket mandrel, wherein the central bore has a common central longitudinal axis that extends through the upper and lower assembly joints;
a tool channel offset from the central bore;
a side pocket tube linearly aligned with the tool channel and configured to receive a gas lift valve; and
a pair of primary flow blocks, wherein the pair of primary flow blocks are located on opposite sides of the tool channel and laterally offset from the central bore, and wherein the primary flow blocks each have a continuous length (LFa) that is at least 35% of the total length (LT) of the central portion of the side pocket mandrel.
