  • Angled chisel insert
    Patent number: 11828108
    Abstract: A cutting element includes a substrate that is axially symmetric about a central axis. The substrate has a radius perpendicular to the central axis and that extends from the central axis to an outer surface of the substrate. A super-hard material is coupled to the substrate, and the central axis passes through the super-hard material. The super-hard material has an external surface defining at least one ridge protruding from a remainder of the external surface. A central point on the central axis is offset from the external surface of the super-hard material by a distance equal to the radius of the substrate. A distance measured from the external surface of the super-hard material to the central point is greatest at a position between 25° and 45° from the central axis of the substrate.

  • Port free hydraulic unibody system and methodology for use in a well
    Patent number: 11821283
    Abstract: A technique facilitates use of a liner hanger in a borehole. A port free hydraulic unibody system including an outer structure having a tubing hanger portion and a packer portion mounted about a mandrel may be constructed so as to avoid the creation of leak paths. A seal system may be employed between the mandrel and the surrounding outer structure to ensure sealing engagement therebetween. The mandrel has a port free section on the downhole side of the seal system, and this port free section is maintained during, for example, actuation of the tubing hanger portion so as to prevent formation of leak paths. An actuator may be located along the mandrel and may be configured to initiate actuation of hanger slips mounted along the tubing hanger portion. An anti-preset mechanism positioned along the mandrel works in cooperation with the actuator to prevent premature actuation of the hanger slips.

  • Formation evaluation at drill bit
    Patent number: 11822039
    Abstract: In a drill bit which has hard-faced cutting or gauge protection elements positioned to be in direct contact with subterranean formation as the bit is rotated, at least one of these elements includes a window positioned to be in direct contact with the formation or cuttings from the formation as the bit rotates and moves forward to drill into the formation. Electromagnetic radiation with wavelength in the range from 100 nm to 2600 nm is transmitted through the window to the formation in contact with the window. Electromagnetic radiation such as fluorescence that returns through the same window is received by a spectrometer. The source and receiver of electromagnetic radiation are both accommodated within the downhole drilling equipment but spaced from the windowed element. The electromagnetic radiation travels along light guides from the source to the window and from the window to the receiver.

  • Apparatus and method for determining borehole size with a borehole imaging tool
    Patent number: 11815352
    Abstract: A downhole borehole imaging tool and methods for determining a borehole size includes a magnetoresistive system and a hub moveably coupled to a fixed tool string. The hub includes a magnet. The magnetoresistive system includes magnetoresistive sensors disposed within the fixed tool string and segregated from the magnet.
