Perforation Lift

• Definition – Ability to unload gas wells in the perforations using gas lift.

• Advantages – Causes lower fluid gradient, lower FBHP, and increases the critical velocity in the wellbore, leading to increased production.

• Evolution – Coil tubing gas lift, casing flow, dual annular lift, below packer lift, and Otis gas pump.

• Easy way to treat below packer/in perfs
