DTI CT Z6 Running Tool

The DTI CT Z6 Running Tool is used to run DB Series Lock Mandrels and attached subsurface control devises into the compatible Profile Nipple.

The Lock Mandrel is made up to the DTI CT Z6 Running Tool at surface and run in hole. During tripping in hole circulation through the Z6 Running Tool Choke is kept low to keep toolstring pressure below the Z6 Running Tool activation pressure. When the Lock Mandrel reaches the Profile Nipple No-Go Shoulder, increasing the toolstring pressure activates the Z6 Running Tool and fully sets the Lock Mandrel. An overpull confirms the Lock Mandrel is set correctly and upwards overpull or light jarring releases the Z6 Running Tool from the Lock Mandrel.
