3 7/8″ * 15000 psi Downhole tester

Tester valve

The downhole tester used for drill stem testing is a full-opening, annulus pressure-operated valve.It permits  measuring multi pleclosed-in

pressures in cased holes where pipe manipulation is restricted and a full-opening string is required.

The nitrogen chamber is charged at the surface to a selected pressure determined by surface temperature and

bottom hole temperature and pressure.

If the intended test requires a permanent packer that uses a stinger mandrel or seal nipple,a variety of Halliburton

by pass tools are available,depending on field application,to help ensure that the formations and downhole

equipment are protected from excessive pressure build up.

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.
