All Terrain Technology

  • AT Rig contains dual drill rods (rod-in-rod) instead of a single rod system.
  •  AT is highly effective in mixed hard soils, including rock formations ranging from 5,000 to 20,000 PSI. Lower downhole pressure helps maintain productivity.
  • AT saves up to 80% water / drilling fluid compared to traditional mud motor systems.
  • In comparison, mud motors transmit only about 50% of power downhole, whereas AT delivers 95% or more of the HDD unit’s inner drive power. This makes AT approximately 40% more efficient than mud motor systems.
  • All Terrain technology reduces jobsite footprint. Mud motor setups require larger space due to additional support equipment, whereas AT requires a smaller setup area, helping minimize environmental disruption.
