    Abstract: Devices and methods for well logging using a wear-resistant electrode are provided. A downhole device may include a drill collar and a first electrode mounted on the drill collar. Further, the first electrode may include a wear-resistant face. The first electrode may be movably coupled within the drill collar, and the first electrode may be configured to extend and retract into a wellbore to maintain contact with a wall of the wellbore. Furthermore, the first electrode may be configured to measure impedance of a geological formation.

    Abstract: Pipes, drill strings including pipes, and methods for use on a drilling rig. The method includes obtaining pipe data for individual drill pipes of a drill string, obtaining a well trajectory for a well, obtaining one or more drilling measurements to be used when drilling the well, planning a first drill string based on the pipe data, the well trajectory, and the one or more drilling measurements, predicting an aging of the individual drill pipes in the first drill string while drilling the well using the first drill string, determining that a risk of failure of one or more individual pipes in the first drill string is unacceptable based on the aging of the individual pipes; and planning a second drill string in response to determining that the risk of failure is unacceptable in the first drill string.

    Abstract: A submersible electrical machine includes a first magnetic package spaced axially from a second magnetic package, a first stator displaced axially from the first magnetic package by a first air gap, a second stator displaced axially from the second magnetic package by a second air gap. The electrical machine can be operated as a generator or as a motor. When operating as a generator, a turbine can rotate the magnetic packages relative to the stators in response to fluid flowing axially across the electrical machine.

    Abstract: An integrated drilling rig machine is disclosed. An integrated power and electronics unit (IPEU) includes all components necessary to transmit power from a generator to rig machines such as a mud pump, drawworks, top drive, etc. A housing contains a rectifier, a transformer, inverter(s), and starter motors. The inverters are coupled to rig machines and the starter motors are coupled to auxiliary devices such as cooling fans, lubrication pumps, communication systems, etc. A controller controls operation of the IPEU according to instructions received from a remote device.

    Abstract: Systems and methods for continuous mud circulation during a drilling operation. The method includes delivering a first flow of drilling mud from a mud supply, through a drill string, into a wellbore, and through a blowout preventer. The drill string is received through the blowout preventer. The method also includes delivering a second flow of drilling mud into the blowout preventer. The second flow is not delivered through the drill string. The method further includes stopping the first flow, and removing or adding a tubular to or from the drill string when the first flow is stopped and while continuing to deliver the second flow.
