      Particle impact drilling is a new drilling technology to penetrate formations effectively without any
change to current drilling equipment and method. Steel particles (2% to 5% of drilling fluid, diameters are
1-3mm) are pumped into HP drilling fluid and ejected from bit nozzles under high frequency (more than
10 million times per minutes) and high speed (more than 100 m/s). It is an advanced drilling technology
that combines impacting of particle and cutting of bit to penetrate formation.
