The select tester valve is a full opening, annulus pressure operated tool, which is main valve, used for drill stem testing operations in cased holes.

This tool 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.

The nitrogen section is composed of the nitrogen case, nitrogen mandrel, floating piston and nitrogen filler valve. The nitrogen acts as an adjustable spring and provides the force needed to close the ball valve. The nitrogen section is charged at the surface to a predetermined pressure according to surface temperature, bottom hole temperature and hydrostatic pressure. These values do not have to be exact because the floating piston allows the tool to compensate for small inaccuracies (approximately 10%).


The metering section is composed of the lower oil chamber, metering cartridge and floating piston. The oil in this section acts as a barrier between the tool and the annular fluid. This insures that only clean fluid passes through the metering cartridge.
