				CAT-VIS, a powdered biopolymer (welan gum), provides viscosity and suspension properties in CAT-I cationic water-based drilling fluid systems.  CAT-VIS is stable in the presence of monovalent and divalent salts that are commonly used in CAT-I systems.  The material does not ferment and it does not require a biocide with use. *Applications/Functions: Provide viscosity and suspension properties, Increase mud carrying capacity in high angle/horizontal wells. *Advantages: Provides enhanced viscosity and suspension properties in muds containing large quantities of sodium or calcium chloride, Has increased stability in cement, Effective in small concentrations, Environmentally responsible, Biodegradable |
