Title: CASING EXIT JOINT WITH GUIDING PROFILES AND METHODS FOR USE
Abstract:
A casing exit joint with guiding profiles and methods for use are provided. In one embodiment, a casing exit joint comprises: a substantially tubular casing joint comprising an inner surface and an outer surface, wherein at least a circumferential portion of the inner surface comprises a plurality of axial inner grooves. In certain embodiments, at least a circumferential portion of the outer surface may comprise a plurality of axial outer grooves. The casing exit joint may be disposed in a wellbore penetrating at least a portion of a subterranean formation, and a cutting tool may cut a window through at least a portion of the casing exit joint. In certain embodiments, the axial inner grooves and/or outer grooves may reduce the amount of milling debris, prevent lateral displacement of the cutting tool, and/or eliminate the need to pre-orient the casing exit joint to achieve the desired exit window.
