Abstract

Anchoring systems for disposition in wellbores and tubular devices comprise a tubular member defined by two or more radially expandable slip members. The upper ends of the slip members are shaped such that when the slip members are in their respective run-in positions and in their respective set positions, a portion of an upper end of one slip member overlaps a portion of an upper end of another slip member so that the longitudinal space between each slip member that is created when the slip members are in their set position are blocked by the upper end of at least one of the slip members. Thus, in their set position, the upper end of at least one of the slip members provides a back-up to a sealing element that can be disposed adjacent to and in contact with the upper ends of the slip members when in their set positions.
