Air Rotary Drilling Method

Air Rotary Drilling is an ideal drilling method to drill in medium to hard-consolidated formations when the introduction of foreign substances such as mud is not permitted.

Advantages of Air Rotary Drilling:
  • Air system efficiently removes drill cuttings keeping borehole open
  • Ability to drill in excess of 800'
  • Increased penetration rates
  • No drilling fluids to dispose of

This method utilizes air as a circulating medium to; cool the drill bit, bring drill cuttings to the surface and maintain borehole integrity. When drilling with a conventional air rotary system, the cuttings are removed from the borehole using high annular pressure created by an air compressor at the surface. The air that is circulated also acts to cool the drill bit as it circulates from inside the drill rod and out and around the bit.
