In various embodiments, the assembly has a tractor for advancing the assembly along the tubing on an inside thereof; at least one engager connected to the tractor, the engager being configured to couple the assembly to a wall of the tubing, such that a stimulus applied to the tubing, e.g. components of force or manipulation of the tubing, can be communicated to produce a response in a part of the assembly. A detector may detect the response when the assembly is coupled to the wall of the tubing, in order to produce data based on the response for determining a location at which the tubing may, or may not, be subjected to at least one operation for freeing the string or a portion thereof.
