  • Shale drill pipe
    Patent number: 9222314
    Abstract: A drill pipe for oil and gas drilling comprises two tool joints and a main portion between the tool joints, with two upsets adjacent to the tool joints, and a central section between the upsets. The outer diameter of the central section of the main portion is less than the outer diameter of the main portion upsets, and the outer diameter of the central section of the main portion is between 4? and 4½?.
    Type: Grant

  • Holding device insertable into the central bore of a tubular drill string component, and corresponding tubular drill string component
    Patent number: 9217298
    Abstract: A holding device insertable into a central bore of a drill string component, the central bore having a first diameter along at least part of a central portion of the drill string component and a second diameter proximate ends of the drill string component. The second diameter is lower than the first diameter. The holding device includes an elongated body forming at least partly a housing for a transmission line. The elongated body has transversal dimensions lower than the second diameter. A plurality of arcuate elements are arranged along the elongated body and distinct from and attached to the elongated body. The arcuate elements are elastically bendable so as to be able to move through the second diameter and have a largest chord greater than the first diameter in a free state so as to be able to expand within the first diameter once past the second diameter.
