  • Patent number: 10087705
    Abstract: A seal assembly for establishing a seal in an annulus between a mandrel and a bore wall includes a mandrel, a radially expandable seal element mounted on the mandrel, and a setting arrangement mounted on the mandrel and being arranged to displace the seal element radially outwardly from a retracted configuration to an extended configuration. The expandable seal element defines a cup seal when in the extended configuration.

  • Publication number: 20160168943
    Abstract: A downhole seal assembly for establishing a seal against a bore wall includes a mandrel, a seal element mounted on the mandrel, a setting support member mounted on the mandrel, and at least one setting element mounted on the mandrel axially between the seal element and the setting support member. Relative axial movement between the seal element and the setting support member over a first actuation distance causes the seal element to be deflected radially outwardly by an axially adjacent setting element. Relative axial movement of the seal element and the setting support member over a subsequent actuation distance causes radial expansion of at least one setting element to further expand the seal element.

  • Publication number: 20160076324
    Abstract: An anchor ring assembly for anchoring to a mandrel includes an annular housing which defines a through bore to permit mounting on a mandrel. A plurality of slips are circumferentially arranged within the through bore of the housing, and a plurality of activator members extend from an external surface of the housing to engage the slips. The activator members are adjustable relative to the housing to extend the slips radially inwardly to engage and grip a mandrel.
