  • Isolation assembly
    Patent number: 11142986
    Abstract: An apparatus that is usable with a well includes a tubular assembly and an expansion tool. The tubular assembly has a radially contracted state and includes a restriction. The restriction is adapted to catch an object that is deployed into the well to form a fluid barrier when caught by the restriction. The expansion tool is deployed downhole with the tubular assembly inside a tubing string. The expansion tool is adapted to deform the tubular assembly to anchor the tubular assembly to the tubing string.
    Type: Grant

  • Buoyancy assist tool
    Patent number: 10316626
    Abstract: A system includes a casing string and a buoyancy assist tool that is disposed in the casing string. The buoyancy assist tool includes a tubular body, a wiper plug assembly, and a degradable member. The wiper plug assembly is disposed inside the central passageway of the tubular body, and the degradable member retains the wiper plug assembly to the tubular body.

  • TOE INITIATOR HAVING AN ASSOCIATED OBJECT CATCHING SEAT
    Publication number: 20160222759
    Abstract: A technique includes installing a tubing string having a toe initiator valve in a wellbore; and opening the toe initiator valve to establish fluid communication between an interior of the string and a region outside of the string. The technique includes using the fluid communication established by the open toe initiator valve to communicate a degradable object downhole to land in a seat of the string; and performing a downhole operation using a fluid barrier resulting from the landed object.
