3. Conclusion
Dry Directional DrillingDry Directional Drilling
1. This technology makes it possible to operate on a widerange of soil conditions, without having to substitute oruse expensive drilling toolsuse expensive drilling tools .
2. Rigs are designed to be compact, resulting in reducedsizes, yet robust, with a remarkable power generated inth ll b k d tthe pull back and torque .
3. DDD systems cost less to operate than the “traditional”wet boring system
4. The use of DDD technology eliminates mud-relatedproblems (flooding of underground rooms, muderuptions).e upt o s)
5. Air does not generate any physical or chemicalpollution, nor does it disturb existing water-bearingstrata or surface streams and it is abundantly available
