  • Publication number: 20240263545
    Abstract: Tubulars are used to seal a leak in completion equipment, such as parted connection (or parted casing) or damaged casing, isolate a casing perforation or an open hole zone, by expanding the tubulars over the leak, perforation, or zone, where the inner diameters of sections of the completion equipment above and below the leak, perforation, or zone are different. Alternatively, the tubulars are used to apply a liner over an open hole section and anchor the liner onto a base casing. The tubulars preferably function as cladding. An apparatus for expanding the tubulars includes a lower fixed-diameter cone, an upper fixed-diameter cone, and a drill pipe passing through the upper fixed-diameter cone and attached to the lower fixed-diameter cone. The drill pipe can slide through the upper fixed-diameter cone or be attached to the upper fixed-diameter cone.

  • Patent number: 6053263
    Abstract: An earth-boring bit has a bit body which connects to a drill string. Three cutters are rotatably secured to a bearing shaft of the bit and a large number of chisel-like cutting elements are secured to each cutter. Each cutting element has a cylindrical base and a cutting end. An elongate crest is located at the tip of the cutting end. A conical chamfer connects the crest and the cutting end. The junction created by the chamfer is non-tangential and reduces the amount of unsupported material at the crest. The conical contour of the chamfer is defined by by a straight line moving in an oval path about the longitudinal axis. The contour of the cutting end avoids abrupt changes and associated stress concentrations. This is achieved by avoiding surfaces of rotation in non-axisymmetric configurations.
