TiGR Priming Valve
A patent pending downhole anti-gas-locking device for rod pumps.
The Vantage TiGR Priming Valve, embodying thousands of hours in design, prototyping and testing, is now pending field trials.
The TiGR Priming Valve is engineered to improve production and rod pump efficiency by equipping a rod pump with an automatic means of sensing and overcoming gas-dominant pump conditions, and can eliminate production losses and operating expenses due to:
Pump off conditions.
The temporary or permanent practice of having rod pumps “on tap or tag” due to gas locking.
The requirement for high compression-ratio pumps.
How it works:
Threads directly onto the bottom of the rod pump’s plunger. No special adapter required.
Production does not flow through the TiGR Priming Valve. It is an isolatable chamber that fills with the fluids and/or gases present in the pump barrel, only responding when gas is dominant in the pump barrel.
The TiGR Priming Valve unseats the pump’s travelling valve, allowing the pump to be primed with tubing fluids, by containing the compressed gas from the downstroke and using that pressure to create an equalizing force during the upstroke.
The integration with the plunger provides a solution with minimal operational risk or changes to pump configuration, only requiring additional barrel length to accommodate its length.
How it’s different:
The TiGR Priming Valve unseats the pump’s travelling valve on the upstroke. This differs from historical tools that utilize the very bottom of the downstroke to create equalization in the pump.
No operational intervention is required - the TiGR Priming Valve is self-sensing and reacts to the presence of gas in the pump.
