NPD - WR-VOi™
The newest development project for Wireline Retrievable Injection Safety Valves is the WR-VOi™ (Variable Orifice Insert) Safety Valve.
Most Injection Wireline Safety Valves use interchangeable orifice "chokes" to get specific differential pressures ensuring proper function downhole. These chokes increase the injection back-pressure during operation. The increased back-pressure reduces the injection efficiency and increases the required horsepower during injection. Also, most Injection Wireline Safety Valves use Flappers and Flow Tubes that are subjected to "hammer" and critical threshold flow levels before proper function.
The API-14A Validated WR-VOi™ uses an variable orifice that actively adjusts to the instantaneous injection flow to maintain a consistent low back-pressure without a Flapper or Flow Tube. The WR-VOi™ is simply a "better mousetrap" for Injection Safety Valve applications. The "passive" and "transparent" functionality allow it to be an effective "Surge Valve" that can be set as low as possible in the well to protect your reservoir from start-and-stop surge damage.
We look forward to discussing your specific well conditions and working with your preferred wellhead provider to solve your most difficult Injection Safety Valve application challenges.
