Abstract

Disclosed are systems and methods for providing a casing exit. One method includes introducing into a wellbore a casing section having an outer sleeve and an inner sleeve rotatably received within the outer sleeve, the outer sleeve defining an outer window and the inner sleeve defining an inner window rotationally alignable with the outer window, wherein the inner sleeve defines a first alignment portion engageable to rotate the inner sleeve, advancing the casing section to a wellbore location with the inner window rotationally misaligned with the outer window, extending a deflector tool within the casing section such that a second alignment portion provided on the deflector tool engages the first alignment portion, and rotating the deflector tool such that the inner sleeve rotates with respect to the outer sleeve and moves the casing section into an open configuration where the inner window is rotationally aligned with the outer window.
