Abstract: The present disclosure describes a dynamic geo-stationary actuation technique that may be incorporated into a rotary steerable system 200. An example method described herein may include receiving a first angular orientation of a rotating housing 201 disposed in a borehole. The first angular orientation may be received from a sensor assembly 205 coupled to the housing 201, and the housing 201 may be coupled to a drill bit 203. A desired drilling direction for the drill bit 203 may also be received. A first trigger signal to a first actuator 206 coupled to the rotating housing 21 may be generated based, at least in part, on the first angular orientation and the desired drilling direction.

Abstract: A well tool drilling tool can include a torque transfer mechanism with an inner mandrel, an outer housing, and at least one pawl which displaces radially and thereby selectively permits and prevents relative rotation between the inner mandrel and the outer housing. A drill string can include a drill bit, a drilling motor, and a torque transfer mechanism which permits rotation of the drill bit in only one direction relative to the drilling motor, the torque transfer mechanism including at least one pawl which displaces linearly and thereby prevents rotation of the drill bit in an opposite direction relative to the drilling motor.
