Reverse circulation drilling is a drilling method which utilizes reverse circulation bits, and rods with double walls to achieve drilling and sample collection. The outer wall has inner tubes that allow the cuttings to be conveyed back to the surface as the drilling process continues.

Reverse Circulation (RC) Drilling is a process of recovering mineral and rock samples or drill cuttings by pumping compressed air down the drill rods between the outer and inner tubes. Upward air flow through the inner tube allows the cuttings to be then lifted to the surface where they are directed through a sample hose into a cyclone in order ...
