  • Patent number: 10337298
    Abstract: A liner hanger seals with casing string 8 having mill scale and supports a liner 98 within a well. The liner hanger includes a tubular anchor 48 and a tubular expander 40. The tubular anchor 48 may be positioned in the casing string 8 using an inner mandrel 10. An actuator assembly 6 forcibly moves the tubular expander 40 into the tubular anchor 48, expanding the tubular anchor 48 to grippingly engage the expanded tubular anchor 48 against the casing string 8 and to form a circumferential seal between metal sealing elements 52 on the tubular anchor 48 and the interior wall of the casing string 8. The metal sealing element 52 is oversized to provide rigidity, heat shrunk onto the tubular anchor 48, and abrasively dressed to remove excess material prior to installation of the liner hanger.

  • Patent number: 9885229
    Abstract: Perforations in an existing borehole are covered with an expandable clad or elongated tubular that is expanded on location with the expansion equipment then removed. The clad is made of a disintegrating material such as a controlled electrolytic material known as CEM and is expanded into position to cover the existing perforations. One or more plugs are run in with perforating guns and the plugs set with the guns moved away from the set plug and fired to make new perforation. After each new perforation is made a ball is delivered to the plug to isolate a portion of the well and the new perforations are treated such as in a fracturing or another operation. Over time or with exposure to well fluids or temperatures the clad disintegrates and the original well drift diameter is regained so that subsequent production or injection is not impeded.

  • Patent number: 9624744
    Abstract: A coiled spring is extended axially and its outside diameter is reduced for the run in position of a tool preferably a liner hanger. Upon release of the stored potential energy the diameter of the spring grows so that contact of the surrounding tubular is made by the spring to at least in part support one string to another. Alternatively, the rotational force from unwinding the spring can drive a slip or other support member radially outwardly into contact with the surrounding tubular and if desired lock the gripping position between the tubulars. Unexpended potential energy of the unwinding spring can also be a residual force to hold the expanded spring to the surrounding tubular. The axial shrinkage of the coiled spring can also be deployed in actuation of the slip in conjunction with rotational movement to advance the slip radially for a grip of the surrounding tubular.

    Abstract: An expandable translating joint comprises a first expandable tubular member having a lower end with a recessed inner wall portion and a second expandable tubular member having an upper end with a recessed outer wall portion. The second expandable tubular member is partially disposed within the first expandable tubular member such that the recessed inner wall portion at least partially surrounds the recessed outer wall portion. A retainer is coupled to the recessed inner wall portion of the first expandable tubular member and disposed within the recessed outer wall portion of the lower second expandable tubular member. An expansion cone is operable to move axially through and radially expand the first and second expandable tubulars. The first expandable tubular can translate relative to the second tubular member both before and after expansion.

  • Patent number: 8905149
    Abstract: Expandable seals have one or more conforming ribs to facilitate creation of a seal to a sealing surface disposed in the well. The conforming ribs comprise a core of material either capped, partially covered by, or entirely covered by a ring. The ring can be formed of a metal that is softer than the metallic core material of each rib. Suitable metals forming the rings include copper formed by metal spun methods. Disposed adjacent to the rings are one or more sealing elements. By moving the rings into the sealing surface during expansion of the expandable seals, the rings close the extrusion gaps between the internal surface of the casing and the expanded tubular member ribs. The rings better conform to the sealing surface of the casing, thereby facilitating the creation of the seal between this sealing surface and each of the sealing elements.

  • Patent number: 8899318
    Abstract: Herein disclosed is a method of applying at least one aggregate to a tubular, comprising attaching the at least one aggregate to a flexible sheet; wrapping the flexible sheet around the tubular with the at least one aggregate between the sheet and tubular. Herein also disclosed is an assembly comprising a tubular, at least one aggregate, and a flexible sheet wrapped around the tubular with the at least one aggregate between the tubular and the sheet. In an embodiment, the at least one aggregate is adhered to the sheet by a first adhesive and the at least one aggregate is adhered to the tubular by a second adhesive, wherein the second adhesive has a higher adhering strength than the first adhesive. In an embodiment, the flexible sheet is removed and the at least one aggregate remains attached to the tubular. The use of such an assembly is discussed.

  • Patent number: 8863854
    Abstract: An apparatus for isolating at least a portion of a tubular for use in a wellbore comprising a first, inner tubular in the form of carrier tube and a second, outer tubular in the form of protective shroud, coupled to the carrier tube. One or more aperture is provided in a wall of the carrier tube for permitting fluid transfer through the tube and one or more aperture is provided to permit fluid transfer through the shroud. A sealing layer is disposed on a surface of the shroud, the sealing layer defining a first configuration permitting fluid flow through the apertures and, on exposure to a selected reactant, adopting a second configuration to restrict fluid flow through the apertures, the sealing layer adapted to return from the second configuration to the first configuration where concentration of the selected reactant falls below a selected threshold.
