A Reverse Circulation Drilling Rig is a machine used to drill and collect rock or soil samples. It is common in mineral exploration, geotechnical work, and deepwater well drilling. The rig uses reverse circulation drilling to bring cuttings straight to the surface inside an inner tube. This method reduces contamination and gives cleaner samples for analysis. The clean samples help geologists make better decisions.
How Reverse Circulation Drilling Works
Reverse circulation drilling uses two tubes inside the drill string. Drilling air or fluid pushes cuttings into the inner tube. The cuttings travel up the inner tube and come out at the surface. This keeps the sample free from drilling fluid and outside contamination. The process is fast and keeps the worksite cleaner.
