Summary
- Sentinel’s use of an appropriately sized centrifuge and properly managed drilling fluids assisted BRH finishing this project in timely manner while reducing risks to pedestrian traffic.
Deep Tunneling Underneath the Great south bay
BRH Garver was selected to install two (2) 450’ lengths of 36” Permalock Casing for the San Antonio Water System’s W-6 Project. BRH awarded the solids control and drilling fluids to Sentinel Solutions.
Unexpected highly reactive clays
BRH was tasked to make these dual drives in densely populated suburban San Antonio. Sentinel was asked to reduce haul-off of whole slurry and maintain rheology throughout the drives.
Experts Solids Control
Sentinel sized the centrifuge based on previous experience with BRH and provided the necessary fluids to maintain hole integrity while keeping mud losses to a minimum. At the conclusion of each drive, anionic flocculants were injected allowing BRH to discharge fluids and keep vac trucks off the roads.
