  • Support tube for a swell packer, swell packer, method of manufacturing a swell packer, and method for using a swell packer
    Patent number: 8794310
    Abstract: Disclosed herein is a swellable packer having a support element. A portion of the support element is substantially adjacent to the base tubular. Another portion of the support element is separated from the base tubular and a portion of the area between the support element and the base tubular is filled with the swellable material. Also disclosed herein is a sealing system including a packer as described above and a method for sealing within a wellbore using a packer as describe above.

  • Swellable downhole device of substantially constant profile
    Patent number: 8651179
    Abstract: A swellable packer device upon exposure to brine in a well. The device may be swellable to a substantially constant profile in spite of significant fluctuations in brine concentrations. Thus, the likelihood of packer failure due to under-swelling or over-swelling is reduced. Indeed, the packer may be employed for long-term operations or isolations ranging from a couple of weeks to twenty years or more without undue concern over packer failure from under or over swelling.

  • Swell packer and method of manufacturing
    Patent number: 8235108
    Abstract: A sealing member. The sealing member can include a support member having an inner bore and a plurality of apertures formed therethrough. An outer swellable element can be disposed about an outer diameter of the support member, and an inner swellable element can be disposed about an inner diameter of the support member. The swellable elements can be unitized with one another through each aperture. A retainer can be disposed at each end of the support member.

  • SWELL PACKER
    Publication number: 20090242189
    Abstract: A swell packer includes a base tubular; a seal member encircling the base tubular, the seal member swelling radially to a seal equilibrium swell upon contact with a particular fluid; and a disc positioned about the base tubular substantially abutting an end of the seal member but not physically connected to the seal member in a manner that limits the equilibrium swell of the seal member, the disc swelling radially to a first equilibrium swell upon contact with a particular fluid.

  • Energy Controlling Device
    Publication number: 20060201371
    Abstract: The present invention provides an apparatus capable of influencing explosive energy during wellbore applications. In one embodiment, a cap or other interfering element may be arranged proximate to an explosive charge prior to detonation. The size and positioning of the element with respect to the explosive charge may be manipulated to achieve an optimum explosive orientation. A ring element having a bore therethrough may be utilized for directing the explosive energy of the charge upon detonation.
