    Sterowanie wierceniem przy użyciu systemu Soft Torque
    (2005) Artymiuk, Jan; Sokalski, Marek
    The system reads top drive torque. The soft torque system adjusts the rotational speed according to torque variations measured, achieving dampening of torsional oscillations on the bit and equipment. The system reacts on torque rate of change and adjusts the speed. Increasing torque reduces the speed proportional to the torque rate of change. A controller adjusts the speed according to torque variations measured. Increasing torque indicates sticking of pipe or bit. Decreasing torque increases the speed likewise. The system easily adapts to existing top drive systems, AC, DC or hydraulic.
