Casing oscillators and rotators have built a reputation as a great method of drilling cased shafts. Drillers who use oscillators or rotators can produce a straighter shaft quicker, with fewer anomalies, and virtually no concrete overrun, meaning lower costs and a better product.
The advantages of oscillators and rotators
- Casing creates a more vertical shaft with minimal defects.
- Significantly cuts back on over excavation, saving the contractor in concrete overrun costs, not to mention any expenses associated with costly anomaly repairs.
- Rotators can rotate casing through harder geological formations and buried obstructions better than a typical conventional drill rig.
- A rotator can drill through the most difficult of geologic conditions requiring casing.
