a relatively thin walled sleeve having a premachined window is disposed at a casing window in a wellbore . the sleeve is set in place with the casing or on a separate run wherein the running tool also includes a dog to align the sleeve premachined window with the casing window both linearly and rotationally in the wellbore . the sleeve is swedged in place in part or completely and a subsequent run provides a lateral liner which extends through both the premachined window and the casing window and seals against the premachined window which will then prevent sand entering the wellbore .
