Abstract: A method for transitioning a rigid or semi-rigid tool around a whipstock having a curved internal guide channel. The apparatus and method entail the tool meeting specific proportion criteria relative to the narrowest part of the curved guide channel through which it must pass and relative to the length and width of the tool. In lateral borehole related applications, if the wider ends portions of the tool are of approximately the same diameter of the borehole, the tool can be stabilized as it travels through the guide channels and creates and transitions a lateral borehole. The disclosure is particularly suited to tools that are rotated through the curved whipstock and in certain applications offers such tools the benefit of a reduced number of segments or links and hence reduced costs and failure points. The method described herein can be used with a variety of tool types and for a variety of purposes and may increase the applicability of tools otherwise only feasible on wellbores of a larger diameter.
