Abstract
A well system having primary and secondary wellbores wherein a completion sleeve is positioned in the primary wellbore and defines a window aligned with a primary wellbore casing exit and upper and lower couplings defined on opposing axial ends of the window. An isolation sleeve is positioned within the completion sleeve and defines a helical slot. The isolation sleeve is movable between a first position, where a engagement device engages the upper coupling and the isolation sleeve occludes the window, and a second position, where the isolation sleeve is moved axially within completion sleeve to expose the window and the engagement device engages the lower coupling. A whipstock assembly includes a latch key that selectively locates and engages an inner profile of the isolation sleeve to move the isolation sleeve to the second position. An orienting key mates with the helical slot to angularly orient the whipstock assembly.
