This drilling method is unique – it uses two rotary drives to move both a drill bit and steel casing together. This technology works well in soft formations (like sand, gravel, cobbles, boulders) to lower risks of hole collapse, lost circulation, and ground movement.
It’s also the best way to build class V injection wells. We have 8 dual rotary rigs and have made more than 8,000 drainage wells in Florida, mainly in Miami and nearby areas. Drainage wells are vital for handling excess water from streets, parking lots, homes, roofs, and highways.
Advantages of Dual Rotary Drilling:
- Faster, controlled drilling through unconsolidated formations
- Reduces or eliminates lost circulation or dredging problems
- Casing seals off the formation as you drill
