Abstract
A deflector assembly for an object in a well. The deflector assembly may include a tubular housing and a core plug. The tubular housing may include a window through a wall of the tubular housing, a deflector below the window. The deflector may include a cavity extending through an axial length of the deflector and a deflector angled surface that is shaped to direct the object toward the window. The core plug may be removably coupleable within the cavity and include a receptacle and a second angled surface that is shaped to direct the object toward the window. The second angled surface is aligned with the deflector angled surface. The core plug may be coupleable with the deflector so as to rotate with the deflector.
