... situations by increasing the torque when required. The overloading indicator prevents overstepping the torque limit of the bit and the BHA. The new parameter map and best-practice recommendations transport the learnings to the field in an easy-to-use manner. drillstring dynamics torsional acceleration...

... and max RPM (blue, red, yellow) over depth, indicating sections of stick-slip (up to ~13,075 ft) and sections of no stick-slip (13,075 ft onwards). The lower plot shows the Root-Mean-Square (RMS) of torsional accelerations measured at the steering unit (red) and at the MWD (blue). It can be clearly seen...
