Abstract:
An apparatus for setting a liner in a wellbore that includes a setting tool attached to a work string. The setting tool includes a stretching mandrel and a liner top releasably attached to the setting tool. The liner top includes banded elastomer sheaths positioned in multiple locations along its length. The apparatus may also include a roller screw, operatively attached to the setting tool, so that a rotational movement imparted to the work string causes a forward, rotational movement of the stretching mandrel and engages the stretching mandrel with an inner portion of the liner top so that a protuberance is formed on the inner portion of the liner top and a groove is formed on an outer surface of the liner top.
