1. A drilling method, comprising:
- rotary drilling a first segment of a wellbore by rotating a drill string with a top drive forming a part of a drilling rig apparatus for a first period of time;
obtaining data from a sensor disposed about the drilling rig apparatus while rotary drilling for at least a part of the first period of time to obtain historical information taken over the at least a part of the first period of time;
based on the obtained historical information from the sensor, determining a proposed oscillation revolution amount for the drill string to reduce friction of the drill string in the wellbore without changing a direction of drilling of a bottom hole assembly on the drill string; and
slide drilling a second segment of the wellbore while oscillating the drill string using the proposed oscillation revolution amount during a second period of time.

11. A drilling rig apparatus comprising:
-
a top drive controllable to rotate a drill string in a first rotational direction during a rotary drilling operation and to oscillate the drill string in the first rotational direction and an opposite second rotational direction during a slide drilling operation; a sensor configured to detect a measurable parameter of the drilling rig apparatus when the top drive rotates the drill string in the first rotational direction during the rotary drilling operation; and a controller configured to receive information representing the detected measurable parameter from the sensor over a period of time during the rotary drilling operation to obtain historical data taken over the period of time and based on the obtained historical data, determine a proposed oscillation revolution amount for the drill string to reduce friction between the drill string and a wall of a borehole while not impacting a direction of slide drilling. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A drilling method, comprising:
-
rotary drilling a first segment of a wellbore by rotating a drill string with a top drive forming a part of a drilling rig apparatus for a first period of time; obtaining data from a plurality of sensors disposed about the drilling rig apparatus while rotary drilling for at least a part of the first period of time to obtain historical information taken over the at least a part of the first period of time, wherein obtaining data from the plurality of sensors comprises obtaining data relating to rotary torque from a torque sensor and relating to at least one of;
weight on bit from a weight on bit sensor, differential pressure from a mud motor differential pressure sensor, hook load from a hook load sensor, pump pressure from a pump pressure sensor, mechanical specific energy from a MSE sensor, rotary RPM from a rotary RPM sensor, or a tool face orientation from a tool face sensor; andbased on the obtained historical information from the plurality of sensors, determining a proposed oscillation revolution amount for the drill string in a clockwise direction to reduce friction of the drill string in the wellbore while not impacting a direction of slide drilling; based on the obtained historical information from the plurality of sensors, determining a proposed oscillation revolution amount for the drill string in a counterclockwise direction to reduce friction of the drill string in the wellbore while not impacting the direction of slide drilling, wherein the proposed oscillation revolution amount in the counterclockwise direction and the proposed oscillation revolution amount in the clockwise direction are different; and slide drilling while oscillating the drill string at the determined proposed oscillation revolution amount. - View Dependent Claims (19, 20)
