The Full Bore Tester Valve is an annulus pressure controlled ball valve and is designed to allow multiple cycles during cased hole drill stem testing

Drill stem testing

Cased hole DST

Brief
The 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 theTester valve greater compatibility and flexibility with other tools in the string.It is fully balanced to annulus pressure and will remain in the closed position while tripping in hole. Operation of the FBTV insensitive to tubing pressure changes

Operation

Once the packer is set, pressure is quickly applied to the annulus to operate the Full Bore 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.

This higher level of pressure prevents the operating mandrel from moving up. In this position, the ball valve will remain open when the annulus pressure is released. To reactivate the tool, annulus pressure is once again increased to 1,300 psi above normal operating pressure. This will reactivate the operating section and return the tool to normal operating mode. The lockout feature can be reactivated as many times as desired without having to remove the tool from the well.
