With the recent increase in unconventional shale drilling, many challenges follow as these wells typically include extended reach lateral sections. These challenges include, but are not limited to: low ROP, stick-slip, and poor WOB transfer along the drill string.
The ArcoPulse utilizes a multi-lobe power section configuration and valve assembly to produce mixed mode oscillations, which act upon the drill-string downhole to reduce torque and drag. The valve assembly converts the energy available from the pumped fluid into a series of pressure pulses. These pulses activate the shock tool, which in turn creates axial motion that breaks static friction.
