ABSTRACT:
A well tool, such as a packer apparatus, is adaptable for insertion on a conduit within a subterranean well having casing therein. The well tool comprises a cylindrical mandrel which is communicable to the conduit. Slip means are carried exteriorly around the mandrel and are movable into expanded position for anchoring the apparatus to the casing whereby subsequent longitudinal movement of the apparatus in at least one direction is prevented. Seal means are circumferentially extending exteriorly around the mandrel and are urgable into sealing relation with the casing to prevent fluid communication thereacross, the seal means comprising at least one section of transversely compressible seamless, knitted elements generally defined by a continuous series of interlocking ductile metal-containing loop members.
