Abstract: A bottom hole assembly (BHA) configured for use in a drill string of a wellsite drilling system. The BHA includes a measuring-while-drilling (MWD) module, a wireless power and data connection, and a rotary steerable system (RSS). The MWD module is configured for coupling to a drill string, and includes a power generation component and a direction and inclination (D&I) survey package. The wireless power and data connection is disposed above a drilling motor in the drill string and for providing power and data connectivity between the MWD module and the drilling motor. The RSS is coupled to the drilling motor for receiving power from and communicating with the MWD module via the wireless power and data connection and the drilling motor.

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: 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: A wireline configurable toolstring is conveyed within a wellbore extending into a subterranean formation via a tubular string to which the wireline configurable tool string is coupled in a manner permitting relative motion of the wireline configurable toolstring and the tubular string. The wireline configurable toolstring converts rotary motion imparted by rotation of the tubular string, or by fluid flow resulting from reciprocation of the tubular string, into electrical energy. The wireline configurable toolstring also comprises at least one wireline configurable instrument powered by the electrical energy.

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.
