  • Automated control of toolface while slide drilling
    Patent number: 10036678
    Abstract: Apparatuses, systems, and methods for controlling slide drilling on a drilling rig are described. The methods include detecting current differential pressure of a mud motor and/or weight on bit (WOB) at a surface of a borehole, predicting current reactive torque of the mud motor based on the current differential pressure and/or WOB, and automatically adjusting surface torque and/or angular offset of a tubular adjacent the surface to counteract the current reactive torque and to keep the mud motor at a desired toolface orientation in the borehole.
    Type: Grant
