  • Patent number: 10316616
    Abstract: A dissolvable bridge plug configured with components for maintaining anchoring and structural integrity for high pressure applications. These components may substantially dissolve to allow for ease of plug removal following such applications. The plug may effectively provide isolation in a cased well for applications generating over about 8,000-10,000 psi. At the same time, by employment of a dissolve period for the noted components, such a plug may be drilled-out in less than about 30 minutes, even where disposed in a lateral leg of the well.

  • Patent number: 10233934
    Abstract: Fracture-resistant and self-lubricating wear surfaces are provided. In an implementation, a machine surface that is subject to wear is coated with or is constructed of a metallic nanostructure to resist the wear and to provide fracture-resistant hardness, built-in lubrication, and thermal conductivity for heat-sinking friction. The metallic nanostructured surface may be used, for example, on a face seal, bushing, bearing, thrust member, or hydraulic flow passage of an electric submersible pump. In an implementation, the metallic nanostructured surface is a nanocrystalline alloy including nanograin twins of a body-centered cubic (BCC), face-centered cubic (FCC), or hexagonal closest packed (HCP) metal. The nanostructured alloy may include atoms of copper, silver, gold, iron, nickel, palladium, platinum, rhodium, beryllium, magnesium, titanium, zirconium, or cobalt, and may provide more hardness and lubricity than diamond-like carbon coatings or carbides.

  • Patent number: 10233724
    Abstract: An element is deployed within tubing extending to a downhole tool. The downhole tool includes a hydraulic tool and a valve coupled between the conveyance string and the hydraulic tool. The valve includes a valve seat having a passage directing the fluid from the conveyance string to the hydraulic tool. Deploying the element includes landing the element on the valve seat such that the element substantially obstructs flow of the fluid through the valve seat passage. The valve is opened to direct the flow of the fluid around the hydraulic tool, wherein opening the valve utilizes pressure generated in response to the element obstructing the flow of the fluid through the valve seat passage. At least a portion of at least one of the element and the valve seat is then degraded by an amount sufficient to permit the element to pass through the valve seat passage.

  • Patent number: 10208560
    Abstract: A pressure disintegrable device includes a first volume that further includes a first portion and a second portion. The first portion is adapted to transmit a pressure applied to the first volume to a second portion disposed on the first portion. The second portion is adapted to decrease a melting point thereof as the transmitted pressure increases beyond a predetermined pressure. The pressure disintegrable device may also include a layer disposed on the first volume that is adapted to create a seal between the first volume and an external structure.
