Abstract: Provided is an expandable liner hanger assembly, a well system, and a method for setting an expandable liner hanger assembly. The expandable liner hanger assembly, in one aspect, includes a radially expandable tubular defining an interior passageway and an exterior surface, and an anchoring ridge extending radially outward from the radially expandable tubular, the anchoring ridge having an entry angle (?1), an exit angle (?2), and a bevel angle (?) greater than zero degrees.

Abstract: A method and device for a radially expandable downhole tool for bearing axial loads upon radial expansion into anchoring and sealing engagement with a downhole tubular positioned in a subterranean wellbore. The device may comprise a radially expandable tubular defining an interior passageway and an exterior surface. The device may further comprise an axial load bearing assembly positioned on the exterior surface of the expandable tubular and having an anchoring sub-assembly for engaging the downhole tubular and bearing axial loads placed on the downhole tool, the anchoring sub-assembly having a plurality of radially extending ridges, each ridge having a hardened anchoring surface and corners, for penetrating into the downhole tubular and a plurality of longitudinally extending milled grooves formed in each ridge, and a sealing sub-assembly for, after the radial expansion, engaging the downhole tubular and sealing the annulus defined between the downhole tubular and the radially expandable downhole tool.

Abstract: A downhole expandable liner hanger positioned in a subterranean wellbore. The liner hanger may comprise a liner and an expansion element. The expansion element may comprise one or more seal elements bonded to the expansion element in an open-ended containment system, wherein each of the one or more seal elements is a nanoreinforced rubber element comprising a polymer host and a plurality of nanostructures.

Abstract: The present disclosure relates generally to equipment utilized and operations performed in conjunction with a subterranean well and, more particularly, to an improved liner hanger system. A downhole expandable liner hanger positionable in a subterranean wellbore may comprise an expansion element. The expansion element may comprise a tubular body. The expansion element may comprise one or more annular seals bonded to the tubular body. The expansion element may comprise a first spike extending from the tubular body. The expansion element may comprise a second spike extending from the tubular body. The downhole expandable liner hanger may further comprise a first slip ring, wherein the first slip ring is disposed around the tubular body of the expansion element between the first spike and the second spike, wherein the first slip ring is configured to expand radially as the expansion element expands.

Abstract: A high-axial load bearing assembly is provided for use with a radially expandable tool such as an expandable liner hanger. Exemplary embodiments of axial load bearing assemblies operate independently of external casing pressure and internal tubing pressure. The assemblies do not rely on movable slips or the physical characteristics of the sealing members to grip the casing and bear the axial load. The gripping and sealing functions are largely separated between gripping and sealing sub-assemblies. Hardened metal features which undergo radial expansion during deployment are provided with expansion stress-relief features.

Abstract: Disclosed is a tubular expansion tool which includes a plurality of stackable piston/slip/spring assemblies that are used to radially expand a liner against well casing along a longitudinal distance “L.” The pistons are repeatedly stroked a short distance “S” with the application of hydraulic pressure. As the pistons are stroked, they move a mandrel-expansion die sub assembly in successive steps a distance “S” to perform the tubular expansion over a longer distance “L.

Abstract: An expansion cone assembly (200) for setting a liner hanger. The expansion cone assembly (200) includes a cone mandrel (202) having an outer frustoconical surface (220), a lead cone (206) slidably disposed around the cone mandrel (200) having a frustoconical surface (228) with a maximum outer diameter (230) and a collapsible cone (204) slidably disposed at least partially around the outer frustoconical surface (220) of the cone mandrel (202). In an expansion configuration, the outer frustoconical surface (220) radially props the collapsible cone (204) such that it has a first maximum outer diameter (232) that is greater than the maximum outer diameter (230) of the lead cone (206). In a retrieval configuration, the collapsible cone (204) axially shifts relative to the outer frustoconical surface (220) such that it has a second maximum outer diameter (234) that is no more than the maximum outer diameter (230) of the lead cone (206).
