Under-balanced drilling and air rotary-percussive drilling are some of the technologies developed to overcome these challenges. Air was substituted for liquid as the drilling fluid on an experimental basis on several wells in the early 1950’s1. The resultant benefits

Pneumatic motor - Wikipedia

A pneumatic motor (air motor) or compressed air engine is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion. Linear motion can come from either a diaphragm or piston actuator, while rotary motion is

Air rotary drilling uses air as a drilling fluid to entrain cuttings and carry them to the surface. High air velocities, and consequently large air volumes and compressor horsepower are required. “Down-the-hole” (DTH) percussion hammers driven by the air stream can be used with this method to rapidly penetrate bedrock materials.
