Abstract:
In accordance with embodiments of the present disclosure, a hybrid drive for use within a rotary steerable drilling tool is provided. The hybrid drive may enable improved directional drilling performance of the rotary steerable drilling tool. The hybrid drive may include a prime mover for rotating a drilling component (e.g., cam used to counter-rotate a steering head) relative to a fully rotating outer housing of the rotary steerable tool. In addition, the hybrid drive may include an electrical motor/generator for adjusting the rotational speed of the cam in response to high frequency changes in rotational speed of the tool housing. The hybrid drive may also include a transmission coupled to the prime mover and the electrical motor/generator for providing mechanical energy from one or both of the prime mover and the motor/generator to rotate the cam (or other drilling component) within the rotary steerable tool.

Claim (Index 12):
The method of  claim 11 , further comprising:\n receiving a signal indicative of a rotational speed of the housing at a control system; and operating the motor/generator to match changes in the rotational speed of the housing to maintain the drilling component geostationary with respect to the subterranean formation based on the signal via the control system.
