  • Solid expandable tubular members formed from very low carbon steel and method
    Patent number: 7621323
    Abstract: A very low carbon steel alloy is provided for use in manufacturing tubular members such as oil country tubular goods. The tubular members may be radially expanded from at least twenty percent to forty percent. Sections or joints of casing formed from the steel alloy may be installed within a wellbore and radially expanded during completion of the wellbore.
    Type: Grant
    Filed: July 23, 2008
    Date of Patent: November 24, 2009
    Assignee: United States Steel Corporation
    Inventors: Gary M. Reavis, Bluford W. Lowery, Ralph R. Myers, Bowman A. Urech

  • Tubular members and threaded connections for casing drilling and method
    Patent number: 6817633
    Abstract: Oil country tubular goods and other types of tubular members are provided with threaded and coupled connections satisfactory for use in drilling and completing wellbores. The threaded and coupled connections are used to join sections of casing with each other to form a casing string which may be used to drill and complete a wellbore. Each tubular member has first and second pin ends with approximately the same thread form and thread profile with different pitch diameters. Standard API couplings may be used with the casing string.
