Hydraulic Oscillator: Revolutionizing Weight-on-Bit Transfer in Directional Drilling
The Challenge of Extended-Reach Drilling
In long lateral and directional wells, drillers face:
-Poor weight-on-bit (WOB) transfer reducing ROP by 30-50%
-High friction factors causing stick-slip and torsional vibrations
-Tool face instability requiring constant correction cycles
-Increased stuck pipe risk in high-angle sections
Our hydraulic oscillator delivers:
✅ 50% friction reduction between BHA and wellbore
✅ 90% improved WOB transfer to the bit
✅ Tool face stability even in complex formations
Operational Advantages
