| 20120312526 | Swelling Packer and Method of Construction - 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. | 12-13-2012 |
| 20130008643 | DOWNHOLE SEALING DEVICE AND METHOD OF MAKING - 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. | 01-10-2013 |
| 20130283593 | METHOD OF MAKING A DOWNHOLE SWELLABLE SEAL WITH A PASSAGEWAY THERETHROUGH - 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. | 10-31-2013 |
