Abstract
A gas vent can include an inner production tube and at least two outer housings. One outer housing is configured to be connected above a tubing anchor, and another outer housing is configured to be connected below the tubing anchor. The inner production tube is configured to extend longitudinally through the tubing anchor. A gas vent system can include an inner production tube which extends longitudinally through a tubing anchor, and an annulus formed between the inner production tube and the tubing anchor. A gas flows through an interior of the tubing anchor via the annulus.
