TiGR Valve
Responsive Gas Lock Mitigation for Rod Pumps.
Maximize Production and Reduce Operating Costs
Rod pumped wells operating under multiphase conditions frequently experience unstable pump behavior, reduced fillage, and suppressed production due to gas interference and inconsistent valve action.
The TiGR Valve is a first-of-its-kind gas lock mitigation tool that adapts dynamically to changing gas-liquid ratios within a standard rod pump.
Threaded onto the plunger, the TiGR Valve tackles gas lock from inside the pump.
Overview
Automatic Response
An isolatable chamber with a gas sensing device that responds to gas lock.
Converts a standard travelling valve into a condition-responsive system.
Reduction in the influence of Gas
Increase and stabilize pump fillage under dynamic conditions.
Reduce non-productive compression strokes.
Enhance volumetric efficiencies.
Shift wells into a more stable operating regime over time.
Ported Intake Sub
Threads onto the plunger in place of the seat plug (API threads).
Production flows around the tool and into the travelling valve through the ports.
Actuator Assembly
A piston assembly with a prong that extends to the top of the ported intake sub.
When gas locked, compressed gas is stored inside the pressure chamber at the bottom of the downstroke.
On the upstroke, the stored energy creates a pressure differential with the barrel and causes the piston/prong to move upwards with enough mechanical force to unseat the travelling valve.
The piston has 3.5 times the surface area than the travelling valve’s ball/seat contact area - creating a mechanical advantage.
Pressure Chamber
Fills with whatever fluid or gas is present in the barrel via the filtered intake at the bottom of the tool.
Fluid/gas movement in and out of the chamber is controlled by the gas sensing assembly.
Gas Sensing Assembly
A ball, seat and cage similar to a travelling valve.
The ball floats in fluids and drops to its seat in gas.
When seated, the tool becomes active and will unseat the travelling valve on the upstroke.
