    Abstract: Various embodiments of methods and systems for wireless power and data communications transmissions to a sensor subassembly below a mud motor in a bottom hole assembly are disclosed. Power and/or communications are transmitted through stationary or fixed coils. By leveraging resonantly tuned circuits and impedance matching techniques for the stationary coils, power and/or communications can be transmitted efficiently from one stationary coil to the other stationary coil despite any vibration and/or misalignment of the two coils.

    CPC classification number: E21B17/003 ,  E21B47/00

    Abstract: The present disclosure relates to a power isolation adapter which can enable the use of multiple power sources in a bottom hole assembly (BHA) by isolating the power sources on a tool bus while maintaining a communication bus across the BHA. Such power sources may be part of a measurement-while-drilling (MWD) module, such as a mud turbine generator, providing power as a DC signal. The power isolation adapter isolates the power sources by blocking DC signals, but maintains an AC communication bus across the BHA. The ability to use multiple power sources in a BHA thus allows for more complex BHA configurations that normally could not be powered using a single power source.

    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: A system for measuring and control of shock and vibration is disclosed. The system may include a bottomhole assembly having a downhole end and an uphole end opposite the downhole end. A drill bit may be located at the downhole end of the bottomhole assembly and a powered rotary steering system may be located in the bottomhole assembly. The system may also include a first drilling mechanics module located in the bottomhole assembly, proximate the powered rotary steering system and the drill bit. The first drilling mechanics module may be coupled in electronic communication to the power rotary steering system. The system may also include a plurality of drilling dynamics measurement units distributed along a length of the bottomhole assembly, between the downhole end and the uphole end.
