RCD

Reverse Circulation Drilling(RCD), also known as airlifting, is effective drilling the 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 setting tanks.

Using RCD Rings is highly efficient, safe, and an environmentally friendly solution for drilling large diameters and deep depths. If you fall into one of the following conditions, RCD is the best solution to deal with it.
