Full Drift Through a Gas Lift Injection Packer Assembly

A gas lift injection system comprising:

• a first production tubing;
• a gas lift injection packer assembly comprising a top sub having a gas inlet port formed therein, a check valve disposed in the gas inlet port, a packer coupled to the top sub, a bottom sub coupled to the packer, and a sleeve disposed within the top sub, the packer, and the bottom sub, wherein an inner wall of the gas inlet port is a housing for the check valve;
• and
• a second production tubing;
• wherein the top sub is coupled to the first production tubing, wherein the bottom sub is coupled to the second production tubing.

A method of gas lift injection, comprising:

• providing a production string comprising production tubing and a gas lift injection packer assembly coupled to the production tubing, wherein the gas lift injection packer assembly comprises a top sub, a packer coupled to the top sub, a bottom sub coupled to the packer, and a sleeve disposed within the top sub, the packer, and the bottom sub, wherein the sleeve forms a micro annulus with the top sub and the packer;
• injecting a pressurized gas into an upper portion of an annulus of a wellbore;
• and
• flowing the pressurized gas through a check valve embedded in the top sub, through one or more injected gas runners formed in the top sub, through the micro annulus, and out of one or more gas outlet port formed in the bottom sub.
