Abstract:
An apparatus and method for locating multiple windows in a wellbore. The windows are associated with lateral wells. The apparatus may include: a running tool connected to a work string, wherein the running tool contains an inner bore being located at a distal end of the running tool; a swing arm having a locating head, the swing arm being pivotally attached within an inner cavity in the running tool, wherein the locating head has a retracted position within the running tool and an extended position extending from the running tool, and wherein the locating head has a shearing surface at an aft end; a biasing member disposed within the inner bore, the biasing member configured to create a force in the direction of the locating head; a shearing rod operatively positioned within the inner bore and engaging a first end of the biasing member so that the shearing rod extends from the inner bore in the direction out of the inner bore towards the locating head, wherein the shearing rod contains a series of individual grooves; and wherein the shearing surface is configured to engage and shear the individual grooves of the shearing rod at a predetermined force in multiple, individual cycles.
