Abstract: A system and a method use dual telemetry for tools located in a wellbore. A first telemetry system and a second telemetry system coordinate communication with the tools. Both the first telemetry system and the second telemetry system may transmit data regarding the tools and/or drilling conditions from the tools to a surface location simultaneously. The first telemetry system or the second telemetry system may communicate with the surface location if communication using the other telemetry system is interrupted. The first telemetry system and the second telemetry system may have a master/slave relationship so that data requests from a specific telemetry system do not interfere with data requests from the other telemetry system.

Abstract: A system for drilling a subterranean wellbore includes a bottom hole assembly (BHA) coupled to a downhole end of a drill string. The BHA includes an electronic controller having a processor. The drill string includes downhole and uphole portions with the downhole portion made up of wired drill pipe and the uphole portion made up of non-wired drill pipe. The downhole portion further includes at least one downhole tool or sensor sub in communication with the BHA via the wired drill pipe communication link. Methods for making sensor measurements, downlinking data and/or commands to the BHA, and actuating a downhole tool make use of the system.

Abstract: Various embodiments of methods and systems for wireless power and/or data communications transmissions to a sensor subassembly above a mud motor in a bottom hole assembly are disclosed. Power and/or data are supplied by rotary modulator and power generation system positioned above the mud motor. Wires may connect to an annular coil. Power and/or communications are transmitted through the annular coil to an inductively coupled second, mandrel coil that is attached to the rotor. By leveraging resonantly tuned circuits and impedance matching techniques for the coils, power and/or data can be transmitted efficiently from one coil to the other despite relative movement and misalignment of the two coils.

Abstract: Various embodiments for wireless power and data communications transmissions between a cartridge in a rotary steering system and components within a drill collar are disclosed. In a certain embodiment, magnetic fields are used to transfer power and data between the cartridge of a rotary steering system and electronics and/or sensors mounted in the drill collar. A first coil is attached to the pressure housing of the cartridge by a shaft containing wires. The turbine in the pressure housing provides an alternating current to the first coil, which is attached to the shaft. Consequently, the first coil generates an alternating magnetic field that passes through the ferrite surrounding a second coil that is attached by wires to an annular pressure housing that is attached to the drill collar. The alternating magnetic field generates an emf in the second coil, which provides power for electronics and sensors mounted in the drill collar.
