How Tailored Drilling Fluids Overcame Unknown Soil Conditions in Horizontal Directional Drilling

Are you working on horizontal directional drilling projects where unpredictable soil and challenging terrain threaten your schedule? CC Underground faced just that when tasked with installing 800 meters of 18” PVC water main pipe beneath dense forest and residential areas, including an uphill drill shot passing 30+ meters below grade. Unknown soil conditions and shallow road crossings made traditional excavation impossible.

Using Di-Corp’s specially designed drilling fluid program, which included Wyo-Ben Extra High Yield Bentonite™ and Earth Pro additives, CC Underground stabilized the bore hole despite a temporary underground pond inflow and completed the project on time and within fluid budget.

If you’re encountering complex soil and terrain challenges, downloading this case study will show you:

  • How tailored drilling fluids maintain hole stability in unknown and varying ground conditions.
  • Why fluid design is critical when working with mud motors and recycling equipment.
  • How CC Underground successfully navigated impassable terrain and water inflows without delays.

The fluid, as designed, stood up to this washout, and the bore hole remained intact.
