Tool positioning and latching system

A method for positioning a tool within a wellbore, the method comprising the steps of:

• providing an interior of a tubular string with a first plurality of grooves, 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;
• providing the tool with a first blade comprising a first plurality of protruding members, wherein the first plurality of protruding members define a first complementary profile configured to lock within the first selected profile;
• providing 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;
• securing a collar directly to the external surface of a torch, a cutter, or a perforating device and attaching the first blade to the collar with a hinged arm, wherein the first blade and the collar each comprise a single point of connection with the hinged arm;
• biasing the first blade in an outward direction to cause locking of the first complementary profile within the first selected profile;
• and
• lowering the tool and the first blade within the tubular string until the first complementary profile locks within the first selected profile, thereby positioning the tool proximate to the first plurality of grooves.

A system for adapting a tool for achieving a selected position within a wellbore, the system comprising:

• a mounting member configured for attaching directly to an external surface of a tool, wherein the mounting member comprises a collar configured for direct attachment to non-threaded external surfaces, wherein substantially all of the collar is positioned concentrically about the tool, and wherein the tool comprises a torch, a cutter, a perforating device, or combinations thereof;
• a blade attached to the mounting member using a hinged arm, a pivotable arm, or combinations thereof, wherein the blade and the mounting member each comprise a single point of connection with the hinged arm, wherein the mounting member retains the hinged arm and the blade in relation to the tool, wherein the blade comprises a plurality of protruding members, and wherein the plurality of protruding members define a first selected profile configured to lock within a plurality of grooves defining a first complementary profile, and wherein the plurality of grooves are positioned within a wellbore;
• and
• a biasing member in communication with the blade, wherein the biasing member continually biases the blade away from the tool for engaging the plurality of protruding members with the plurality of grooves.
