- Versatile — compatible with casing advancement systems
- Enables well construction in difficult, caving formations
About Wash Rotary Drilling
Wash rotary drilling uses a rotating drill bit combined with a circulating drilling fluid (water, mud, or air) to advance the borehole and remove cuttings from the subsurface. This method is highly effective in unconsolidated and semi-consolidated formations where borehole stability requires fluid support, and is the preferred technique for constructing large-diameter monitoring wells and injection wells.
IET employs wash rotary methods as part of comprehensive environmental and geotechnical drilling programs, particularly where deeper wells or large-diameter casings are required for remediation systems. Our CME and Schramm truck and track rigs are well-suited for rotary drilling in a wide range of formation types, providing the depth capacity and torque needed for demanding well construction projects.
