Abstract
A system for lining a junction between a main bore and an auxiliary bore includes a first tubing adapted to line at least a portion of the main bore. The first tubing has a lateral opening therein. A second tubing has a junction shield extending outward therefrom. The junction shield has a larger transverse dimension than the lateral opening and is adapted to contract to a smaller transverse dimension to pass through the lateral opening into the auxiliary bore.
