Abstract: Systems and methods for drilling a wellbore include delivering electrical energy to a downhole end of the wellbore. A tapered drill string, with larger drill pipes connected in an up-hole portion with a turbine and an electrical generator and a smaller drill pipes coupled in downhole portion may be used to deliver the electrical power. A turbine and generator may be sufficiently sized to harvest the necessary hydraulic energy and safely operated in a subterranean environment. A lower portion system carried by the downhole portion of the drill string is electrically coupled to the generator through the downhole portion of the drill string to utilize the electric power provided by the electrical generator.

Abstract: A power beaming system delivers electric power in laser light from a first location to a remote second location. The laser light has a high energy intensity level defining a hazardous illumination area and a low energy intensity level defining a safe illumination area. The system includes guard circuitry emitter(s) and corresponding detector(s). The guard circuitry forms a detection area about the hazardous illumination area to detect objects in proximity to the hazardous illumination area. A controller directs the guard and power beam circuitry according to sequentially activated safety modes to operate at a low energy intensity level, to scan in a defined pattern, to adjust operation of the detector(s), and to set guard circuitry parameters based on a time value, an object detection value, or a change to the delivered electric power. An output coupled to the controller and power beam circuitry controllably permits or prevents operation at the high energy intensity level.

Abstract: The present disclosure relates to a rotary steerable tool operable to steer a drill bit for drilling a wellbore. In some embodiments, the rotary steerable tool is operable in an acknowledgment mode to confirm receipt of a downlink transmission by performing a detectable acknowledgement action that continues to rotate the drill bit, but temporarily suspends the steering of the drill bit for a period of time by maintaining the valve motor in a stationary rotational position relative to the valve.

Abstract: An extendable member diagnostic assembly determines performance of one or more components of a rotary steerable system. Based on the determined performance, an operation can be altered, such as a drilling operation. Performance may be based on measurements received from one or more sensors associated with components of the extendable member diagnostic assembly. For example, performance may be based on the time to transition a valve between states where the valve controls actuation of an extendable member, downhole temperature, downhole pressure or any other factors that affect performance of components that are used to perform the drilling operation. A controller receives the measurements from the one or more sensors and updates baseline parameters to determine an accurate performance. Using real time data to determine performance increases efficiency of an operation by eliminating unnecessary replacement of components and indicating that a downhole tool should be retrieved prior to failure.
