  • Patent number: 10825008
    Abstract: Methods and apparatus identify downhole equipment and correlate input data with the equipment to improve planning and/or inventory operations. For some embodiments, oilfield equipment or tubular goods such as drill pipe include a shaped recess along an outer circumference for receiving a tag cartridge by shrink fitting. Once tagged, detector system configurations at pipe yards may facilitate logging the presence and location of each drill pipe and correlating specific data, such as inspection data, to each drill pipe. Further, this correlation populates a database utilized to achieve other business functions such as forecasting number of additional drill pipe needed to purchase, invoicing customers according to actual tracked wear/use of the drill pipe being returned, and providing well or job specific drill string population using known history pipe joints.

  • 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.
