Full Hydraulic Drilling Rigs (Reverse Circulation Drilling Rig)

Reverse circulation drilling (RCD), also known as airlifting, is an effective drilling method that exploits compressed air, as it is injected into the drill pipe below water level, to reduce the density of the internal water column and remove slurries through the circulation. The mixture of water, air, and cuttings are then flushed out through the drill pipe into settling tanks.level, to reduce the density of the internal water column and remove slurries through the circulation.
