Abstract
Systems and methods for providing a casing exit include a casing section having a generally cylindrical outer sleeve including a proximal end and a distal end. The outer sleeve may define an outer window extending between the proximal end and the distal end. A generally cylindrical inner sleeve may be received within the outer sleeve and may define an inner window. The inner sleeve may be moveable between a first position in which the inner window is misaligned with the outer window and the inner sleeve substantially closes the outer window, and a second position in which the inner window is aligned with the outer window. A deflector tool may be configured to engage the inner sleeve and move the inner sleeve from the first position to the second position.
