Drill Stem Testing Tools Tubing Tester Valve
The Tubing Tester Valve (TTV) is a single shot annular pressure controlled flapper valve designed to be used during cased hole testing and perforating operations for pressure testing a workstring while running in the hole
The Tubing Tester Valve is always assembled with the flapper valve in the active position. This allows a small differential from the fluid below the valve to open the flapper to fill the string, and applied pressure from above the valve seals the flapper for tubing pressure tests. The tubing string can be pressured up against the flapper as many times as required.
When the tool is required to be disabled, pressure is applied to the annulus until the selected rupture disk bursts, allowing the mandrel to shift and causing the flap of the valve to be held in the open position. Once the rupture disk has been fired the tool remains fully open.
