The Indexing Tool is used to orientate the desired tool into desired rotational position.
Attach to the tool string and lower into the wellbore to desired depth. Tool
is functioned by picking up and setting back down repeatedly until desired
effect is achieved.
Each time tool string is picked up and set down the Indexing swivel will
rotate 30°. This is useful when trying to retrieve debris that has fallen
beside downhole equipment during fishing operations.
Generally ran between mechanical jars and pulling tool but can be used in other applications.
