  • Apparatus and methods of cleaning and refinishing tubulars
    Patent number: 7950450
    Abstract: A method for cleaning and/or altering an inside surface and shape of a tubular is disclosed. The method includes placing a surface finishing tool in the tubular, energizing the surface finishing tool, and causing extendable assemblies therein to extend radially to contact an inside diameter of the tubular. Moving the surface finishing tool axially and/or rotationally while the extended members are in contact with the inside diameter of the tubular cleans debris from the inside surface of the tubular. In another aspect of the invention, the tool burnishes the inside diameter of the tubular, thereby altering the surface characteristics and rounding the tubular.
    Type: Grant
    Filed: July 6, 2004
    Date of Patent: May 31, 2011
    Assignee: Weatherford/Lamb, Inc.

  • Method of cleaning and refinishing tubulars
    Patent number: 6758275
    Abstract: A method for cleaning and/or altering an inside surface and shape of a tubular in a wellbore. The method includes placing a surface finishing tool in the tubular, energizing the surface finishing tool, and causing extendable assemblies therein to extend radially to contact an inside diameter of the tubular. Moving the surface finishing tool axially and/or rotationally while the extended members are in contact with the inside diameter of the tubular cleans debris from the inside surface of the tubular.
