Side Pocket Mandrels

The Vanoil Side Pocket Mandrels are primarily designed for gas lift and are available in sizes 2-3/8 through 7 inch tubing.

The Vanoil Side Pocket Mandrels provide full opening tubing bore while receiving any manufacturer’s 1 inch or 1 1/2 inch outside diameter gas lift valves.

The Vanoil Side Pocket Mandrels have a positioning orienting sleeve to guide the Kickover tool into precise alignment with the side pocket. The slot in the orienting sleeve and tool guard guide the valve until it latches in place.

The Vanoil Side Pocket Mandrels are manufactured from AISI 4130, 13CR, S13CR, or 9Cr-1MO steels. All materials are procured to ASTM standards.

The Vanoil Side Pocket Mandrels are designed for use with a top BK-2 latch and a bottom collet latch, and can be run in highly deviated wells as well as dual completions. Mandrels feature a side pocket profile to receive gas lift valves, chemical injection valves, dummy valves, circulating valves, dump kill and shear orifice valves. Different porting configurations on the side pocket are available for casing flow, chamber lift and waterflood applications.

The Vanoil Side Pocket Mandrels are welded using ASME qualified welders and procedures; uniformly heat-treated using a quench and temper process and pressure tested in accordance to strict design specifications.
