The oscillator is designed to generate low-amplitude axial oscillations in the drill string and to decrease the downhole friction. As a result it improves transmission of WOB and decreases directional stress especially during directional drilling.
Oscillator improves weight transfer to the bit and BHA steerability. The tool is compatible with PDC bits, including drilling in marginal reservoirs and quick azimuth turns. There is a possibility for extended-reach drilling without reciprocation, wiper trips and fluctuations in weight transfer to the bit. The result is increased rate of penetration.
Oscillator enables extended reach drilling with significant increase of ROP, extended bit life, decrease of POOH and chance of differential sticking.
