  • An Introduction to Reverse Circulation Drilling

    Reverse Circulation (RC) drilling produces rock chips rather than a Core sample. The RC method produces sample from depth by pulverizing rock with compressed air and a percussive hammer and returns it to surface through an inner tube and collects it through a cyclone then into a sample bag. Reverse Circulation (RC) is often used in conjunction with a multi-purpose rig to drill RC pre-collars …

  • Reverse Circulation Drilling | RC Drill Rigs | Ranger

    Air Core and Reverse Circulation are methods of drilling using high pressure air and a dual-walled drill pipe. High pressure air is forced down the drill rod annular between the inside pipe (sample tube) and the outside pipe. When the air reaches the bit face the air is forced around and creates a vacuum (a ventury).
