The select tester valve is a full opening, annulus pressure operated tool used in cased holes for the drill stem testing as the tester vale

Select tester valve drill stem testing tools

The select tester valve has the capabilities of taking multiple downhole closures where pipe manipulation is restricted and a full opening string is desired. This tool has the same basic features of the 15K LPR-N Tester Valve plus additional features that include:

Ø The ability to lock the ball valve in the open position at any point during the test.

Ø The ability to reactivate the tool for normal operations.

The select tester valve is composed of four basic sections; ball valve section, upper hydraulic section, nitrogen section and the metering section.

The ball valve section contains the ball valve and the mechanism that rotates the ball when the tool is activated; the ball is rotated to the open position allowing the reservoir to flow into the testing string.

The upper hydraulic section is contained between the upper annulus ports and the nitrogen filler valve. The critical part of this section is the metering (power) cartridge and selector.
