Whether used for primary (placement of grout as a hydraulic seal in the wellbore) or secondary applications (remedial operations including leak repairs, splits, closing of depleted zones), the addition of silica fume enables a well to achieve full production potential. Besides producing a blocking effect in the oil well grout that prevents gas migration, it provides these advantages:
- -Improved flow, for easier, more effective application
- -Dramatically decrease permeability, for better control of gas leakage
- -Increased durability and compressive strength
- -Lightweight
