Mechanical Indexing Tool
The Mechanical Indexing Tool from Reservoir Group Well Intervention Products & Services is designed to provide slow, controlled rotation of a Coiled Tubing BHA without the need to pump through the Coil.

This is particularly useful when used above Fishing and Debris Removal Tools. The tool is functioned by setting weight down on the BHA & then picking up. This leads to the lower collar of the tool indexing at a pre-determined angle. At the end of each stroke, the torque induced is mechanically locked in position by a spring-loaded piston. Indexing can be repeated as often as desired.
