Nippleless Tubing Test Tool

Quickly locate tubing leaks with the DTI Nippleless Test Tool.

The DTI Nippleless Test Tool is run in hole below the suspected leak location. Shock Shearing the activation pin and then setting down weight securely packs off the Nippleless Test Tool so an attempt can be made to pressure test the tubing.

Picking up the toolstring equalizes across the Nippleless Test Tool and then further pick up un-sets the tool. The DTI Nippleless Test Tool can now be moved up the tubing and re-set as many times as is required by simply setting down weight.

The results of tubing pressure tests at each Nippleless Test Tool setting point, will determine the location of the tubing leak.
