2. 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

4. 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

6. 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.

7. ADVANTAGES OVER STANDARD GAS LIFT MANDREL

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.

9. 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.
