The present disclosure describes a dynamic geo-stationary actuation technique that may be incorporated into a rotary steerable system. An example method described herein may include receiving a first angular orientation of a rotating housingdisposed in a borehole. The first angular orientation may be received from a sensor assemblycoupled to the housing, and the housingmay be coupled to a drill bit. A desired drilling direction for the drill bitmay also be received. A first trigger signal to a first actuatorcoupled to the rotating housingmay be generated based, at least in part, on the first angular orientation and the desired drilling direction.

Dynamic geo-stationary actuation for a fully-rotating rotary steerable system

An assembly for inclusion between a drill bit and a drill string, the assembly having an overrunning clutch mechanism that disengages the drill bit from the drill string during the 'slip' portion of a stick-slip cycle to allow the drill bit to freely rotate faster than the drill string. The assembly further includes a rotational vibration dampener operatively connected between the overrunning clutch and the drill bit. The vibration dampener may include a fluid chamber with viscous fluid or restrictions to fluid flow to effect dampening. During normal operation, the one-way overrunning clutch remains engaged to transfer torque between the drill string and bit, while the torsional damper is in its maximum displaced position to transfer the load. During slip, the drill bit is disengaged until its speed is lower than the drill string speed. Torsional vibration dampener dampens sudden impulse force of the overrunning clutch re-engaging.

An example downhole motor may include a first housing and a second housing coupled to the first housing at a movable joint. A turbine may be within the first housing in selective fluid communication with a bore of the first housing. A biasing mechanism may be coupled to the movable joint and the turbine. The biasing mechanism may alter an angle between a first longitudinal axis of the first housing and a second longitudinal axis of the second housing by altering an orientation of the movable joint.

A drilling optimization collar for use proximate a drilling tool within a wellbore includes a fiber optic sensor filament that is sized and configured to fit within a groove formed within the drilling optimization collar. The drilling optimization collar may be a pipe segment that is sized and configured to be installed in a drill string proximate the drilling tool, and may have a plurality of sensor elements. All or a portion of the sensor elements may be formed by discrete segments of the sensor filament, and as such, the sensor filament includes sensor elements that are configured to sense a condition of the wellbore and a load on the drilling optimization collar.
