Rotary
Rotary drilling is a proven and efficient method used for large diameter and deep drilling applications across mining, water, and infrastructure projects. The method uses continuous rotation of the drill bit combined with air or drilling fluids to advance the borehole and efficiently remove cuttings.
Rotary systems are well suited for applications requiring high productivity, large diameter holes, and reliable performance across varying geological conditions. Depending on the formation, drilling can be completed using air rotary systems for competent rock or mud rotary systems for softer, unstable, or unconsolidated formations where borehole stability is critical.
Our rotary drilling capabilities support a range of applications, including:
- Large diameter and deep drilling programs
- Blast hole drilling
- Water well drilling
- Exploration pre-collars
- Drilling in variable ground conditions using air or mud circulation systems
Successful rotary drilling requires the right equipment, experienced operators, and a thorough understanding of ground conditions. Our teams work closely with clients to select the appropriate drilling method and execute programs safely, efficiently, and with consistent results.
Reverse Circulation
Reverse circulation (RC) drilling is a highly productive sampling method used extensively for mineral exploration, resource definition, and grade control programs. The dual-wall drill pipe system provides efficient sample return while reducing contamination, delivering representative samples for geological and geochemical evaluation.
RC drilling is well suited for projects where rapid penetration, high sample volumes, and timely geological information are critical. Modern RC systems can be configured for a wide range of drilling conditions and are commonly used to support exploration programs, open pit operations, and resource development activities.
Our RC drilling capabilities include:
- Mineral exploration and resource definition programs
- Grade control drilling for open pit mining operations
- Pre-collars and pilot holes for diamond drilling programs
- Geochemical sampling and geological evaluation
- High-volume drilling in variable ground conditions
Effective RC drilling requires the right equipment, experienced operators, and a strong understanding of ground conditions. Our teams work closely with clients to optimize drilling parameters, maximize sample quality, and deliver reliable data to support informed geological and operational decisions.
Flooded Reverse
Flooded reverse drilling is a specialized rotary drilling method used for large diameter and deep hole applications where conventional air circulation is not effective. By maintaining a controlled water or fluid-filled borehole, the system improves hole stability, supports efficient cuttings removal, and enhances drilling performance in challenging ground conditions.
This method is particularly effective in formations where maintaining borehole integrity, reducing dust, and improving sample recovery are critical. Flooded reverse systems are commonly used for large diameter drilling programs, production applications, and projects requiring controlled fluid circulation.
Our flooded reverse drilling capabilities include:
- Large diameter and deep drilling applications
- Dewatering, and pre-collar programs
- Soft, fractured, or mixed ground conditions
- Applications requiring improved hole stability and reduced dust generation
Successful flooded reverse drilling requires careful management of drilling fluids, equipment selection, and operating parameters. Our experienced crews utilize specialized systems to maintain effective circulation, optimize drilling performance, and deliver reliable results in demanding conditions.
