ROTARY MUD DRILLING
Rotary Mud Drilling (RMD) is the most commonly used method of drilling. In direct RMD water or water with additives/mud is pumped down a drill pipe out through ports or jets in the drill bit. The fluid then flows up the space between the hole and drill pipe, known as the annular space.
The fluid carries the drill cuttings in suspension to the surface of the borehole. At the surface the fluid is channelled into settling pits or tanks where most of the cuttings settle out.
Clean drill fluid is then picked up from the opposite end of the settling area. The drilling fluid is then re-circulated down the hole, the process is repeated until the drilling is complete.
Advantages of Rotary Mud Drilling
- It is the least expensive drilling method
- Fastest drilling method through soft formations e.g. sand, clay layers and soft rock
- The hydrostatic pressure of the drilling fluid will keep a otherwise collapsing soft formation open
Disadvantages of Rotary Mud Drilling
- Not recommended for soil or site investigation drilling due to cross over of soil samples
- Cannot penetrate hard rock formations

A simple, and reliable low investment, drilling technology for boreholes. Primarily used for unconsolidated materials, it will drill any material, including rocks, and is not troubled by boulders cobbles, or large gravel. Requires no compressors, and needs only one vehicle.
It is a non-invasive water drilling method, allowing discovery, testing and water development, as progress is made. It is an appropriate method for water wells, for mineral prospecting, site investigation and remediation. This rig will drill to 120 meters depending on the conditions and sequence of strata. At only 450 Kg (1000 lbs), the smallest standard machine can be man-handled on its own wheels to places which would be inaccessible to heavier equipment.
