  • Patent number: 9010428
    Abstract: The swelling rate of a swelling packer element or a conforming foam screen material is accelerated with heat. Ferromagnetic particles or electrically conductive resins or polymers are interspersed in the swelling material and heat is generated at the particles by an inductive heater. A dielectric mandrel or base pipe can be used to focus the heating effect on the ferromagnetic particles or the electrically conductive resins or polymers in the sealing element or swelling foam screen element to focus the heating there without heating the base pipe. The heat accelerates the swelling process.

    Abstract: The annular space around a tubular string has a shape memory material that is in a low profile configuration for run in. After the desired position is obtained and the annulus has cement delivered to fill the annular space, the shape memory device is triggered to revert to an original shape that spans the annulus to seal the tubular and the wellbore sides of the annular space against gas migration through the cement. The structures can have varying run in shapes and can also have original shapes that when the material is triggered will act to displace cement to enhance its compaction on the tubular or the wellbore wall. Combinations of shape memory alloys and polymers are also contemplated to enhance the seal against gas migration.

    Abstract: A sliding sleeve has a sensor that detects plugs (darts, balls, etc.) passing through the sleeves. A first insert on the sleeve can be hydraulically activated by the fluid pressure in the surrounding annulus once a preset number of plugs have passed through the sleeve. Movement of this first insert activates a catch on a second insert. Once the next plug is deployed, the catch engages it so that fluid pressure applied against the seated plug through the tubing string can moves the second insert. Once moved, the insert reveals port in the housing communicating the sleeve's bore with the surrounding annulus so an adjacent wellbore interval can be stimulated. The first insert may also be hydraulically activated after a preset time after a plug has passed through the sleeve. Several sleeves can be used together in various arrangements to treat multiple intervals of a wellbore.

  • Patent number: 7661471
    Abstract: Preformed ribs are held closely to the swelling element and then are allowed to assume an expanded position to capture the ends of the swelling element. Many variations are possible one of which is retaining the ribs in a run in position with a band that releases by interaction with well fluid. In another embodiment the ribs are of a shape memory material and go to the enlarged state after a time and exposure to well fluids. The swelling action of the element could urge the ribs to the expanded position. Alternatively, a retractable sleeve can be actuated after a delay using a piston and a sealed compartment where a material must dissolve or otherwise go away before the piston can stroke to remove a retainer from ribs that can then move out.

  • Publication number: 20090255690
    Abstract: Methods and devices for retaining a packer element in a set condition within a wellbore and for preventing or minimizing extrusion of the packer element after setting. A packer device includes a plurality of deformable packer elements which radially surround a packer mandrel. One or more of the packer elements is contained against axial extrusion using a packer containment system. The packer containment system includes a flexible metal backup ring, which partially encases the packer element by substantially covering at least one axial side and a portion of the exterior radial surface of the packer element. The packer containment system also includes a plurality of annular support rings, or “petal rings” which have petal-shaped radial protuberances with slots between them.

  • Patent number: 7559366
    Abstract: A wellhead seal assembly forms a metal-to-metal seal between the inner and outer wellhead members. A metal seal ring has inner and outer conical walls separated by a tapered slot. An energizing ring has inner and outer annular members that are separated by an annular cavity. When the energizing ring is moved further into the slot, the cavity width decreases but remains to provide a preloaded radial force to the seal ring.

  • Publication number: 20090038802
    Abstract: A packer includes a seal element and a piston. The piston compresses the seal element to form an annular seal in the well. A pressure wave, such as a pressure wave that is caused by a chemical reaction or the detonation of an explosive, is generated in the packer to at least partially assist an operation (the setting of a slip, setting of the seal element, etc.) of the packer. In some implementations, the chemical reaction or explosive detonation occurs in response to a predetermined movement of the piston.

  • Patent number: 7422058
    Abstract: A packer device and methods of use for a packer within uncased wellbore to form a complete fluid seal. The packer device includes a central mandrel body that retains a plurality of nested, telescopic expanding elements that are moveable outwardly from the mandrel body. The mandrel body and expanding elements are surrounded by a load-distributing structure as well as a sealing element, which is typically comprised of elastomer. The packer device is hydraulically actuated to urge the expansion members radially outwardly against the load-distributing structure and the sealing element. Because there are a number of discrete expansion elements, the packer device is better able to create a fluid seal within an uncased borehole with surface irregularities.
