Abstract:
1. A sealing and anchoring apparatus for use in a wellbore tubular member having an inner wall, the apparatus comprising: (a) a top swage member disposed within the tubular member, the top swage member having a longitudinal center axis: (b) a first sealing member disposed about the top swage member and having a top end, a bottom end, and a continuous plurality of expandable circumferential ribs, the first sealing member being made of a metal hard enough to be embedded within the inner wall of the tubular member; (c) a second sealing member attached to the first sealing member and having a top end, a bottom end, and a continuous plurality of expandable circumferential ribs, the second sealing member being made of a metal hard enough to be embedded within the inner wall of the tubular member; (d) a bottom swage member disposed within the second sealing member, the bottom swage member having a longitudinal center axis; (e) a setting tool driving the top swage longitudinally downward along the top swage's longitudinal axis and driving the bottom swage longitudinally upward along the bottom swage member's longitudinal axis, the setting tool thereby expanding the first and second sealing members such that the circumferential ribs of the first and second sealing member at least partially embed into the inner wall of the tubular member, the first and second sealing member forming a seal with the tubular member upon expansion, the first and second sealing member anchoring to the tubular member.
