Abstract

This invention relates to an assembly and method for forming a hydraulic seal at the junction of a multilateral well bore drilled through a window in at least a main well bore comprising a tubular member which is run into the well bore casing and has a sealing member positioned about the tubular member for seating, at least one orientation member being provided for orientation of the tubular member and sealing member in the main well bore casing, and having a tubular sleeve member for insertion in the well bore which has an aperture through at least one side of the tubular sleeve member for alignment of the aperture with the window and having a seating surface on the inside of the tubular sleeve member proximate the aperture, with the aperture in some embodiments being adjustable, and having a deflection member positioned and releasable sealed in the tubular sleeve member for deflecting the tubular member through the window in the well bore when the tubular member is run into contact with the deflection member, and having at least one orientation member for orientation of the deflection member relative to the window in the at least well bore casing and for aligning the aperture in the tubular sleeve with the window and a method of using the assembly to form a seal at the junction which can be executed in one run into the well bore casing in at least one embodiment.
