NOVELTY - The apparatus has a drill tubular (5) that couples to a drill bit (7) to rotate the drill bit. A steering device (9) couples to a drill string (6) and imparts a force on the drill string to control a direction of drilling. A controller (11) communicates a control signal comprising information for directing actuation of steering device for steering drill bit in an intended drilling direction. The controller directs steering device to provide a compensating force on drill string that prevents or reduces azimuthal deviation from the intended drilling direction due to drill bit walking.    USE - Apparatus for drilling borehole into earth formation for various purposes such as hydrocarbon exploration and production, geothermal production and carbon dioxide sequestration.    ADVANTAGE - The borehole is drilled in an intended azimuthal direction by automatically compensating for drill bit walking. The automatic aspects do not require operator intervention and thus the compensating force is applied continuously or at a high rate as needed such as when an inclination force is being applied. The maximum force capability of the steering device is exceeded such as when the user calls for applying the maximum capable force in the inclination direction. The controller reduces the force being applied in the inclination direction and applies the appropriate walk compensation force so that drilling in the intended azimuthal direction is maintained. If the survey tool measuring the azimuth of the already drilled borehole detects drill bit walking that is not being compensated, the user can adjust the percentage value to correct the walking.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for drilling borehole into earth formation.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a drill string having a drill bit placed in a borehole penetrating the earth.
