  • High temperature well packer
    Patent number: 4296806
    Abstract: A well packer for use in geothermal wells or stem injection wells. The packer can be anchored to the inner wall of a casing string to resist differential pressure in either direction. The anchoring means includes a single set of slip elements which are hydraulically or mechanically set. The packer includes a sealing unit with packing elements especially adapted for high temperature wells. The packer can be simply released from the casing by upward tension on the tubing.
