X Check Set


To confirm that the BT “X” Locks have been set in the appropriate landing nipple.


Install desired shear pin and attach to tool string, lower into wellbore. Set down on top of lock mandrel and jar down, remove toolstring from wellbore and inspect the BT Check Set Tool. If the pin is sheared in the BT Check Set, this will indicate that the lock mandrel is set correctly, if it is not sheared, this will indicate that the fishneck of the lock mandrel is not all the way down into the set position and should be dealt with accordingly.
