Abstract
A method and system for intersecting a first, cased well bore, includes forming a second well bore that extends to a region of the first, cased well bore to be intersected. A mill guiding device is positioned in the second well bore and a milling assembly is inserted into the second well bore. The milling assembly is guided along the mill guiding device and contacts an upper external shoulder of a casing coupling of a casing in the first, cased well bore. The mill preferentially removes material from a convex portion of the casing above and adjacent to the upper external shoulder the casing coupling; and removes material from the casing coupling and the adjacent casing until the first, cased well bore and the second well bore are fluidly connected.
