    Abstract: A T-shaped slip is retained in an opening of a slip ring to drive the slip in opposed directions to and away from the surrounding borehole wall along a cone. The slip ring and cone do not come together when the slip is engaged. The opening allows release of a lock ring first with the slip engaged followed by release of the slip from the borehole wall. The slip ring and cone come together during removal from the borehole. A travel stop on the axial slip movement is provided to prevent guides on the slip from exiting a track or dovetail on the cone when the slip ring and cone are in contact during removal of the plug or packer. Extension of the guide from the cone track can happen if the slip moves through an enlarged portion of the borehole. The travel stop prevents this.

    IPC: E21B33/128

    CPC classification number: E21B33/128

    Abstract: A compression set sealing element preferably 85A-95A TDI-Ester Polyurethane is compressed axially and retained against extrusion by CEM anti-extrusion rings. The compressed state of the sealing element is locked in by a degradable lock ring assembly. The mandrel is secured to an upper end of a slip cone and a breakable slip ring is secured by a wireline setting tool until the set position is reached. The slip ring breaks into segments that are pulled up the slip cone as the setting tool pushes on a sleeve to axially compress the sealing element and lock in the set. The sealing element is retained against extrusion by CEM anti-extrusion rings. When the setting tool is removed a ball seat is exposed for delivery of a ball to build pressure into the formation for fracturing. The entirety of the plug then disintegrates from well fluid exposure.

    CPC classification number: E21B33/129

    Abstract: Plug devices have an expander swage element, a rupturable slip element and a pusher sub. The pusher sub and slip element have a control protrusion and recess interface which guides segments of the ruptured slip element radially outwardly into engagement with a surrounding tubular. The slip element is formed of a degradable material.

    Abstract: An annularly shaped structure serves as a support and seal when pushed out on a ramp. A continuous seal in a groove is used on one or two sides to enhance sealing. A separate annular structure for sealing can be disposed adjacent to the shape having alternating longitudinal slots so that each structure is targeted to a different purpose. The structures disintegrate when made of a disintegrating material such as for example a controlled electrolytic material (CEM) so that removal of the barrier can occur after a treating operation such as fracturing where many such barriers are deployed. The slots have enlarged holes at their ends to reduce stress concentration that can lead to cracking.

    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.
