Dialog offers the Split Shot cutter service which is a vertical shaped charge jet cutter positioned across the collar to be cut and held in place by a magnetic positioning tool.  After detonation, the collar is cut or split allowing the pipe to be pulled free.  Unlike most jet cutters that have a flared cut, the cut of the Split Shot is clean and allows the pipe to be pulled free without any additional drag or damage to the casing.  With a smooth cut and no debris left in the hole, operations may continue without the need of additional milling operations.
