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.

Working rig machines for deep drilling 7500 psi rated drilling equipment for the future
(2010) Artymiuk, Jan; Lengersdorf, Frank; Loland, Jens Helge; Sokalski, Marek
Prospecting with longer drilling wells, at greater depth of water, sets greater and greater technical challenges before designers, producers and users. Especially marine drilling, in new and unprospected areas, where exploration works are planned in the close future, where will necessitate involving higher deadweight capacity of on-water rig construction, machines of higher torque on the string, and more powerful mud pumps. Hence the need of making new equipment capable of performing necessary works safely and effectively.
