Improve system efficiency over traditional lifting methods

Especially suited for high-pressure, deepwater, and subsea installations, Barrier Series gas lift systems lower costs and downtime by improving the pressure integrity of the entire wellbore environment.

Complete gas lift wells and improve performance with the combined benefits of Barrier Series gas lift valves and the MMRG-2V-B dual-pocket side pocket mandrel. The MMRG-2V-B mandrel is based on the existing, field-proven MMRG-2V configuration with a dual inline, redundant, leak-tight seal.

Enhanced capability and reliability

A barrier-qualified check valve system that provides a metal-to-metal seal between the tubing and casing annulus is available in 1-, 1 1/2-, and 1 3/4-in injection-pressure-operated (IPO) valves and orifice valves for some barrier valve options.

The availability of dual bores and communication portals in the barrier mandrel allows for two separate and distinct, retrievable, flow control check-valve devices that work independently to simultaneously serve both the flow control and the pressure barrier requirements of the gas lift system.

The barrier mandrel is a round-body, fully machined mandrel with a one-piece, twin 1 1/2-in bore pocket design with a dual-tool discriminator containing a tubing-to-casing barrier valve (TCBV). The TCBV prevents communication between the tubing and casing when the normal operating gas lift valve is removed from the primary pocket.
