Abstract:
1. A system for positioning a tool within a wellbore, the system comprising: a first plurality of grooves disposed within an interior of a tubular string disposed within the wellbore, wherein the first plurality of grooves defines a first selected profile, wherein the first selected profile is defined by a first selected spacing of the first plurality of grooves; a first blade in communication with the tool, wherein the first blade comprises a first plurality of protruding members, and wherein the first plurality of protruding members define a first complementary profile configured to lock only within the first selected profile; an additional blade interchangeable with the first blade, wherein the additional blade comprises an additional plurality of protruding members, wherein the additional plurality of protruding members define an additional complementary profile configured to lock only within an additional selected profile, wherein an additional selected spacing of said additional complimentary profile is different from the first selected spacing defining the first complimentary profile, and wherein the additional blade bypasses the first selected profile without locking within the first selected profile as the blade moves along an interior surface of a tubular string; and a collar configured for direct attachment to an external surface of the tool; a hinged arm, wherein the first blade and the collar are connected with the hinged arm, and wherein the first blade and the collar each comprise a single point of connection with the hinged arm; and a biasing member in communication with the first blade, wherein the biasing member continually biases the first blade toward the interior of the tubular string to cause locking of the first complementary profile within the first selected profile, wherein the tool comprises a torch, a cutter, a perforating device, or combinations thereof.
