Abstract (en)
[origin: WO2021050335A1] Systems and methods for damping torsional oscillations of downhole systems are described. The systems include a downhole string comprising a disintegration device and a damping system at least one of in and on the downhole string, the damping system configured to damp torsional oscillations of the downhole string. The methods include installing a damping system at least one of on and in the downhole system with the downhole system including a downhole string having a disintegration device and the damping system is configured to damp torsional oscillation of the downhole string.
