Drilling techniques
DRY SYSTEMS
We carry out various types of drilling with dry systems, depending on ground consistency, depth and well diameter. We have 3 recently acquired dry rotary rigs as well as several percussion rigs.
- 1Dry rotary drilling: up to 800 mm in diameter and a depth limit of about 50 m. For greater depths, the system can be integrated with percussion drilling with a probe.
- 2Percussion drilling with probe: 800 mm diameter at a depth of about 100 m.
