Abstract
An oscillation reduction tool configured to prevent or reduce high frequency torsional oscillation by torsionally decoupling a rotary steerable system from a bottom hole assembly, which includes a drilling motor. The tool may convert high frequency torsional oscillation into an internal axial movement without axial displacement of the tool's outer housing. The oscillation reduction tool may flatten an amplitude of high frequency torsional oscillation spikes throughout a spring arrangement. The mechanical energy associated with the internal axial movement is reduced through an internal shock absorbing mechanism, such as fluid movement through a nozzle or annular space. The oscillation reduction tool functions to reduce high frequency torsional oscillation independent of the weight on the bit of the drill string.
