Description:
Shubh-THV is a Carboxy methyl starch-based filtration control agent meeting Drilling specification. It used as additive to control fluid loss in most water-based fluid system. Shubh-THV is functional in Simulated well site water as well as saturated salt environment and does not increase fluid viscosity. Shubh-THV is non-damaging and can be used in both Drilling Fluid and reservoir Drill-in Fluid application.
Applications:
- Lower filtration rate in most water-based drilling fluid system
- Improve bore-hole stability
- Flocculate dispersed drill cuttings in clear water drilling
- Maintain filtration control without detrimental viscosity increase
- Effective with fast drilling non-dispersed system.
Functionality:
- Additive to control fluid loss
