Project Challenges
- Sand and clay formation
- The Pink Line is constructed along high traffic roads, resulting in very difficult handling
Drilling Fluid Challenges
Choosing the appropriate drilling fluid for this project was a challenge due to the land formation of the project area. The drilling fluids must contain good clay inhibitors and fluid loss properties due to the need to drill into clay and sandy formations to create supporting walls for bore piles. Furthermore, the slurry had to be incorporated with a thixotropic fluid that is stable against salt contamination.
