Downhole window finder system

Abstract

An apparatus for finding a pre-existing downhole window includes a body having a deflector ramp and a cavity, and an extendable dog disposed in the cavity, the dog mechanically moveable between a retracted position and an extended position into the pre-existing window. In some embodiments, the apparatus includes an axially moveable sleeve disposed adjacent the extendable dog. A downhole window finding apparatus includes a deflector including a window finding assembly, and a running tool removably coupled to the deflector, wherein the window finding assembly includes an extendable member and an axially moveable sleeve retaining the extendable member. In certain embodiments, a fluid flow path extends through the running tool and the deflector to the window finding assembly. In some embodiments, a shear bolt removably couples the running tool to the deflector and includes a fluid passage fluidicly coupling a flow line in the running tool to a flow line in the deflector. A method of finding a pre-existing downhole window is also disclosed.
