ABSTRACT:
The present disclosure is directed to a gas lift system adapted to provide a gas injection point to a deeper location in a wellbore. A turn-over suspension mandrel can be landed inside a side pocket mandrel and connected to a gas lift valve on one end and a coil on the other end. A length of production tubing can extend from the side pocket mandrel. The production tubing can include a production packer to seal the annulus between the tubing and the well casing. The turn-over suspension mandrel can be constructed such that gas entering the gas lift valve is directed down through the coil and into the wellbore beneath the production packer. A plug can be placed at the bottom of the coil in order to prevent blowouts during installation of the gas lift system. An alternative embodiment of the present disclosure provides a coil and plug hung from a gas lift valve of a pack-off assembly.
