Abstract:
A tool and method for drilling a secondary hole (window) from a pre-determined position within a well bore into the adjacent rock or formation. The invention includes an internal (relative to the production tubing) primary deflection wedge transitioning into an externally attached (relative to the production tubing) conical device that aids in the exit from the production tubing through the production casing, where a significant standoff exists between the smaller production tubing (completion) and the larger ID production casing. The primary deflection wedge serves as a directional guide to exit the production tubing. The conical device provides a way to transition and support a milling device to exit the adjacent casing at a desired angle without having the milling device move off the preferred course. This two-part assembly is called a tandem wedge kick off assembly.
