Abstract
A well system including a parent wellbore, a lateral wellbore extending from the parent wellbore, and a reentry window assembly installed within the parent wellbore and including a completion window assembly having a window and providing an upper coupling, a muleshoe, and upper and lower slots provided on opposing axial ends of the window. An isolation sleeve is positioned within the completion window assembly and includes a sleeve alignment key, a sleeve coupling, and an engagement device. A whipstock is matable with the sleeve coupling and an aligning tool is operatively coupled to the whipstock and engageable with the muleshoe to angularly orient a whipstock face to the window. The isolation sleeve is movable between closed and open positions to isolate the lateral wellbore, and the sleeve alignment key interacts with the upper and lower slots to angularly orient the isolation sleeve while moving between the first and second positions.
