  • Publication number: 20240125185
    Abstract: A device for use downhole in a drill string includes a body that is cylindrical. The body has a longitudinal axis and top and bottom threads that can couple the body to other elements of the drill string. A radial shock absorber is coupled to an exterior of the body. The radial shock absorber has a piston with a piston axis. A portion of the piston extends to an exterior of the body. The piston can move along the piston axis between a retracted position and an extended position. In addition, a spring is located between the body and the piston. The spring can bias the piston, along the piston axis, radially outward relative to the longitudinal axis of the body.

  • Patent number: 11873686
    Abstract: A downhole tool has a main body that is cylindrical and includes a top coupling that couples to a drill string. A second body that is cylindrical is positioned at least partially within the main body. The second body has a bottom coupling that couples to a drill bit. Springs are positioned within the downhole tool and transmit an axial force to the drill bit. A first set of grooves is formed on an interior of the main body, and a second set of grooves is formed on an exterior of the second body. Balls travel within the first and second sets of grooves. At least some of the balls simultaneously engage the main body and the second body.

  • Patent number: 11713665
    Abstract: Methods, systems, and storage media are presented for operating a drill string within a well. Exemplary implementations may: detect, using one or more sensors, data representing an analog control command sequence; analyze the analog control command sequence; determine that the control command sequence represents a command to change an operational mode of the drill string from a first operational mode to a second operational mode; and transmit a signal to an actuator of the drill string, the signal representing an electronic command to activate the actuator in such a way as to change the drill string from the first operational mode to the second operational mode. In some embodiments, the analog control sequence may comprise a predetermined sequence of rotational inputs, vibrational inputs, pressure inputs, or a combination thereof.

  • Patent number: 11697968
    Abstract: A rupture disc assembly and a float tool incorporating the rupture disc assembly is disclosed. The rupture disc assembly may include a rupture disc assembly comprising a rupture disc, an upper tubular portion and a lower tubular portion, and a securing mechanism for holding the rupture disc between the upper and lower tubular portions. A float tool for creating a buoyant chamber in a casing string may include the rupture disc assembly and a sealing device for sealing the lower end of the casing string, the buoyant, sealed chamber may be created there between. In operation, applied fluid pressure causes the rupture disc to move downward. The rupture disc may be shattered by contact with a surface on the lower tubular portion. Full casing internal diameter may be restored in the region where the rupture disc formerly sealed the casing.
