HK - CMS (CARBOXYMETHYL STARCH)

HK-CMS is a carboxymethyl starch-based filtration control agent meeting drilling specifications. It is used as an additive to control fluid loss in most water-based fluid systems. HK-CMS functions effectively in simulated well-site water as well as saturated salt environments and does not increase fluid viscosity. It is non-damaging and can be used in both drilling fluids and reservoir drill-in fluid applications.

Advantages

• Lower filtration rate in most water-based drilling fluid systems.
• Improves bore-hole stability.
• Flocculates dispersed drill cuttings in clear water drilling.
• Maintains filtration control without detrimental viscosity increase.
• Effective with fast-drilling non-dispersed systems.
