The Cup Type Test Tool is typically made up with a bypass valve above it, and lowered into the wellbore. The test tool is run to depth with the bypass valve closed. With the pack-off head or the pipe rams closed at surface, pressure is applied on the annulus and charted to determine whether there is a leak off. If a pack-off head is used, connections may be made up and the work string lowered into the well until a bleed off point is found. Once the leak point has been determined, the test tool is retrieved by; bleeding off the annulus pressure, opening the bypass valve, and pulling the assembly from the wellbore.
