Abstract

The invention comprises gas lift apparatus including a generally tubular mandrel defining a main longitudinal bore therethrough and including pocket walls defining a longitudinally extending pocket laterally offset from the main bore and generally divided therefrom. The pocket has an open upper end for insertion of a gas lift valve. The pocket walls further have ports extending laterally therethrough on both sides of pocket, i.e. between the pocket and the main bore of the mandrel and between the pocket and the exterior of the mandrel. On one side of the pocket there are at least two such ports longitudinally spaced from each other, and on the other side of the pocket there is at least one port disposed longitudinally between the aforementioned pair of ports. The invention further comprises a gas lift valve adapted to be received in the pocket, and when so received, operable to permit communication between the port or ports on one side of the pocket and the port or ports on the other side of the pocket.
