Minimize Risk and Maximize Profitability IN ULTRAHIGH-PRESSURE LIFT APPLICATIONS Valves designed to maximize gas passage and handle extreme pressures Mandrels with dual external check valves that provide barriers to enhance completion integrity Complete solutions deliver field-proven results in the harshest conditions

APPLICATION & ADVANTAGES Any Completion incoorporating Standard Side-Pocket Gas-Lift Mandrels Deepwater, Sub-Sea, high Pressure and/or highly corrosive well environments. Wells in which it is critical to prevent corrosive fluids from entering into Annulus during Gas Lift Valve changes. Wells which require High Injection Rates ADVANTAGES Secondary Barrier Aerodynamic Check Dart Eliminate Unloading of Casing Annulus Accepts standard 1” & 1.5” GLV and latches Bypass channel to accommodate multiple lines Special Running OD Clearance

Dual Bellows An internal bellows-protection system prevents bellows overtravel, and a non-compressible silicon fluid provides support for bellows when high differential pressures are applied to the valve. This reduces operational failures, nonproductive time (NPT), and operating costs.

ADVANTAGES OVER STANDARD GAS LIFT MANDREL S.No. Description Weatherford DVX Mandrel Standard Gas Lift Mandrel 1 CHECK VALVES QUALIFIED per stringent TR2385 testing standards Yes No 2 Valves designed to maximize gas passage and handle extreme pressures. 3 Dual CV-2 DVX external check valves provide a true second barrier to prevent wellbore fluids from entering the casing annulus, which maintains completion integrity by protecting the casing string from high pressures and corrosive fluids. 4 Complete solutions that have passed extensive testing and deliver field-proven results in the harshest conditions. 5 Custom-designed grooves can be machined on the side of the mandrel to accommodate multiple control lines without increasing the mandrel OD. 6 Assembly can be configured to meet the highest API 19G1 V-1 certifications. 7 Unloading of the casing annulus is not required after changing live gas-lift valves via wireline, which reduces production downtime.

DEEPWATER ENVIROMENTS Qualified for the world’s toughest DEEPWATER ENVIROMENTS The CV-2 DVX reverse-flow check-valve system has passed stringent North Sea flow-erosion testing and meets sealing criteria for maximum well-containment capabilities per API 19G2 and guiding document TR2385. A small package with A BIG RESPOSIBILITY Even the tiny, aerodynamic darts of our DVX check valves have passed rigorous physical testing to enhance completion integrity.
