Abstract: A method of making a downhole swellable seal with a passageway therethrough includes, perimetrically surrounding a first tubular with a first substantially nonswellable material, perimetrically surrounding at least one second tubular with a second substantially nonswellable material, positioning the at least one second tubular adjacent the first tubular, perimetrically surrounding the first tubular and the at least one second tubular with a swellable material, curing the first substantially nonswellable material, curing the second substantially nonswellable material, and curing the swellable material.

Abstract: An expandable liner hanger features carbide or other hard particles adhered to the outer surface of a tubular mandrel that is expanded using vulcanized rubber to retain the carbide during run in or set. The rubber can be directly applied to the outer surface of the mandrel or to a split ring that is subsequently secured to the outer surface of the mandrel. The rubber can also be mounted in an exterior recess to protect the carbide during running in from being knocked off with impact. A binder can be applied to the carbide or to the rubber for better fixation of the carbide when vulcanizing the rubber. The rubber moves with the expanding mandrel while binding the carbide until contact of the carbide to the surrounding tubular transfers the liner string weight to the surrounding tubular through the carbide.

Abstract: Sealing devices such as packers comprise a sealing element having one or more non-elastomeric fibrous sealing material layers formed by a plurality of fibers. The plurality of fibers may comprise one or more of natural material, metallic material, plastic material, or other non-elastomeric sealing material. The non-elastomeric fibrous sealing material layers may be formed by weaving the plurality of fibers, braiding the plurality of fibers, or forming a fibrous mass of the plurality of fibers. During operation, the non-elastomeric fibrous sealing material layers are radially expanded causing compression of the non-elastomeric fibrous sealing material layers. As a result, at least a portion of the air volume within the non-elastomeric fibrous sealing material layers is displaced by non-elastomeric fibrous sealing material causing the sealing element to engage a sealing surface, thereby forming a seal.

Abstract: A method and assembly for reducing a radial gap between radially proximate components including a setting member having a first dimension that partially defines the radial gap, the setting member including a circumferential groove extending radially from the first dimension, and a first toroid having a second dimension, the setting member operatively arranged to engage with the first toroid, wherein increasingly engaging the setting member with the first toroid enables a boundary dimension of the assembly to be extended toward the radial gap for reducing the radial gap, the circumferential groove operatively arranged to catch the first toroid when the setting member is fully engaged with the first toroid.

Abstract: A swelling element packer is made with internal rings that are either split or scrolled. After the swelling element is built on a temporary mandrel a longitudinal seam of a variety of designs is cut through the element. This allows the rapid deployment of the element on the tubular that will be a part of a string and will serve as the final mandrel. The assembly is then magnetic pulse welded or crimped so as to urge the open ends of the rings to move toward each other and become secured to each other and further opening the possibility of attaching parts on the ring itself to the underlying tubular by displacing or otherwise removing the swelling material that was between the ring and the final mandrel when the magnetic pulse process began. The rings can be embedded wholly within the element or can extend beyond the opposed ends.

Abstract: A swelling element on a packer has a trough formed on a longitudinal axis. The control line or cable or conduit that needs to run along the string where the packer is mounted is first wrapped in a preferably non-swelling underlayment that can be a loose scroll or have its seam sealed. A swelling cover is placed over the underlayment using a seam that can be longitudinal or spiral to allow rapid deployment. The covering assembly for the control line or conduit is placed in the slot of the swelling element of the packer. The line or cable continues out opposed ends and can be secured to the tubular string with clamps. The control line can be covered with a swelling material and forced into a groove that runs the length of the packer swelling element.

Abstract: Disclosed herein is a downhole sealing device. The device includes a swellable member, and a passageway having a perimetrically continuous wall. The swellable member is configured to cause sealing between a downhole structure and a plurality of tubulars when in a swelled condition, the plurality of tubulars are routed through a plurality of voids extending longitudinally through the swellable member, each of the plurality of voids has perimetrically continuous walls surrounding each of the plurality of tubulars.
