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.

A downhole tool for enlarging a borehole, the tool including a body having a central axis, an uphole end, a downhole end, a bore extending from the uphole end, and an aperture extending radially from the bore to a radially outer surface of the body. Additionally, the tool includes a mandrel disposed in the bore, the mandrel having a first end, a second end, a radially outer surface, and a radially inner surface. The mandrel outer surface includes an inclined surface. Further, the tool includes a first blade disposed in the aperture. The first blade has a radially retracted position and a radially extended position configured to engage with a borehole sidewall to enlarge the borehole. The mandrel is configured to translate axially relative to the body to slide the inclined surface along the first blade to transition the first blade between the radially refracted and extended positions.

A guide assembly for running a liner through a borehole extending through a subterranean formation, the guide assembly having a central axis, a first end configured to be coupled to the liner, and a second end opposite the first end. The guide assembly includes a guide shoe disposed at the second end, a drive assembly including a radially outer housing, and a rotor concentrically disposed in the housing. The rotor has a first end distal the guide shoe and a second end fixably coupled to the guide shoe, and is configured to rotate about the central axis relative to the housing about the central axis.
