Tubing and annular gas lift
A gas lift system may be installed within a well to allow gas lift operations where gas may be injected into the annular area of the well while producing fluids through the interior of the production tubular or upon demand may be reversed so that gas may be injected into the interior of the production tubular while producing fluids to the annular region of the well. In order to allow bidirectional production on demand two types of gas lift mandrels are installed as part of the production tubular. Both types of gas lift mandrels are configured such that gas lift valves are mounted to the exterior of the mandrels. In order to facilitate the desired direction of gas flow through the two types of gas lift mandrels a plug and packer system with or with out one way valves may be utilized to direct and contain the pressurized gas flow within the well.
1. A method for producing fluids from a well comprising:
pumping a gas, at a surface, into a region between a production tubular and a casing, injecting the gas into the fluids within the production tubular from the region between the production tubular and the casing,
producing the fluid to the surface through the production tubular,
stopping the production of fluid to the surface through the production tubular pumping the gas, at the surface, into the production tubular,
injecting the gas into the region between the production tubular and the casing from the production tubular, and
producing the fluid to the surface utilizing only the region between the production tubular and the casing without removing the production tubular from the well.
