Subcontractors specializing in microtunneling, pipejacking, and HDD use specific drilling fluids to carry out their projects. The success of excavation at optimal costs depends on the properties of drilling fluids to achieve targets such as:
- Advance Rates
- Lubrication
- Reducing Cutterhead Wear
- Carrying Cuttings from the Cutterhead to the Surface
- Ensuring the Stability of the Advancing Face
- Preventing Water Ingress
- Avoiding Fluid Losses to the Ground
- Minimizing filtrate
- Facilitating Drill Mud Treatment
