Drilling Fluids & Additives
Dando fluids & chemicals are formulated to be efficient, economic, and environmentally friendly.
It often becomes necessary to introduce fluid to the hole, even whilst drilling with air as the main flushing medium, to assist with lifting cutting, to stabilise the borehole, or reduce frictional forces.
Water is obviously the easiest and most inexpensive fluid to use, but it often becomes impractical due to its physical limitations. In these situations the physical characteristics of the water are modified with additives to suit ground conditions. The three main additives are:
- Hydratable Clays
