Abstract

Apparatus for completing a subterranean wellbore and associated methods of using provide relatively uncomplicated and convenient access to a parent wellbore lower portion from a lateral wellbore liner which extends into the parent wellbore above the lower portion. The apparatus is utilized to form an opening through a portion of the liner which overlies the parent wellbore lower portion, thereby providing access thereto. In a preferred embodiment, the apparatus includes a milling guide having an axially extending guide profile formed therein, which guide profile is capable of directing a mill toward the liner portion to form the opening. The milling guide is capable of being anchored in the liner to thereby fix its axial and rotational alignment relative to the liner portion.
