The Hydraulic Oscillator enhances the efficiency of weight-on-bit (WOB) transfer during drilling by generating longitudinal vibrations. These self-induced oscillations help to reduce friction between the bottom-hole assembly (BHA) and the wellbore.

This means the hydraulic oscillator can significantly improve drilling performance across various drilling modes—particularly in directional drilling using downhole motors—by:

• Enhancing the effectiveness of WOB transmission

• Reducing the likelihood of BHA sticking or differential sticking

• Minimizing torsional vibrations

As a result, the hydraulic oscillator contributes to smoother, more efficient drilling operations, especially in complex well trajectories.
