Drill stem testing

The Select Tester valve is a full-opening, annulus pressure operated tool. With applied pressure, the tool can be locked open and then returned to the normal operating sequence at any time. The ball valve operates independently of pressure changes from operations such as acidizing and fracturing. This gives the Select Tester valve greater compatibility and flexibility with other tools in the string.This tool has the same basic features of the 15K LPR-N Tester Valve plus additional features that include:

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

- 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.


Once the packer is set, pressure is quickly applied to the annulus to operate the Select Tester valve. This creates the differential pressure that acts across the operating section to move the mandrel down, causing the ball to rotate to the open position. To close the ball, annulus pressure is released to zero. The nitrogen section acts to move the operating mandrel up. This upward travel of the mandrel rotates the

ball valve back to the closed position. To activate the lockout feature, the normal operating pressure is increased by 1,300 psi.
