DescriptionThe BTR-1.0 tubing retrievable gas lift mandrels are made up as an integral part of the production tub-

ing when preparing a well for gas lift, chemical injection, or other special applications. This mandrel uti-lizes 1.0 inch flow control devices. If the mandrel is used in gas lift operations, it is designed to be usedwith injection pressure operated gas lift valves.

These mandrels are designed with a long tapered upper lug and lower pressure lug to facilitate man-drel passage during installation and removal from the well. Side guards plates are welded to the up perlug and mandrel body. This design provides protection and containment for flow control equipment andprevents damage to the equipment during installation or removal from the well.

The BTR-1.0 tubing retrievable gas lift mandrels are available in J55, N80 and L80 grade material.
