Packer Expanded By Upper Valve Patents (Class 166/130)
  • Patent number: 10018010
    Abstract: The frack plug has a sealing element that reforms when set to hold differential pressure. The element is granular with adhesive to hold the granular particles together but allow the shape to reform under setting force. The adhesive can be broken down with a chemical agent or in other ways to allow the seal to reform to the sealing position at the desired depth. As a result the structural components can disintegrate and the seal assembly can fragment into small pieces that can be circulated out of the well or allowed to drop to the hole bottom. The seal can have particles of controlled electrolytic materials (CEM), natural or synthetic sand, swelling or non-swelling rubber. The assembly can contain pellets that selectively release to initiate the breakdown of the structural components of the frack plug.

  • Patent number: 9291028
    Abstract: The present invention relates to a plugging device (1), comprising a packer device (4) for pressure tight sealing of a pipe. The packer device (4) comprises a cone device (10) comprising a first cone (12) and a second cone (14), each having their base faced towards each other and each comprising a tapering surface (12a, 14a). A first packer supporting device (20) is provided on a first side of the cone device (10), a second packer supporting device (22) is provided on a second side of the cone device (10) and a packer body (50) provided is between the first packer supporting device (20) and the second packer supporting device (22). The first and second packer supporting devices (20, 22) comprise supporting arms (24) having a first end (24a) movably connected to the plugging device (1) and a second end (24b) connected to either a front supporting element (30) or a rear supporting element (40).

  • Publication number: 20080271898
    Abstract: A wellbore pressure isolation apparatus is deployed in a wellbore and has a sealing element that can be activated to seal against an interior surface of a surrounding tubular. Once set, a ball valve in the apparatus restricts upward fluid communication through the apparatus, and another ball valve in the apparatus can restrict downward fluid communication through the apparatus. These ball valve can have disintegratable balls intended to disintegrate in wellbore conditions after different periods of time. To facilitate deployment of the apparatus in a horizontal section of the well bore, the apparatus has a plurality of rollers positioned on a distal end. In addition, the apparatus has a ring disposed about the body between the distal body portion and an adjacent body portion. The ring has an outside diameter at least greater than that of the adjacent body portion to facilitate pumping of the apparatus in the wellbore.

  • Patent number: 4332267
    Abstract: An improved mounting and sealing assembly is provided for a rotating ball valve required to open under increased differential pressures and close against high flow rates. The valve assembly includes a trunnion-mounted ball and two pressure biased sealing assemblies. The primary seal constitutes an elastomeric seal element which is axially shiftable into engagement with the ball, and the secondary seal comprises a metallic element which is also axially shiftable relative to the ball. To open the valve, the seals are moved in sequence axially away from the ball and the hydraulic seal is fully broken before the ball is rotated. In closing, the ball is rotated to its closed position and the seals then moved axially in sequence into contact with the ball.
