Natural Tapioca Starch Dosage Form: Tablet

HT high temperature, filtration control additive is a special modified starch derivative used to reduce filtration in most water-based drilling fluids including fresh water, seawater and saturated brine up to 300A F. It is designed to replace SHARKSTARAR in applications with the BHT>250A F. SHARKSTARAR HT will encapsulate drill cuttings and exposed wellbore formations to reduce particle dispersion and reactive shale formation swelling. Subject to bacterial degradation, a biocide is recommended to prevent fermentation in fluids which are not salt saturated.

Applications/Functions
Control filtration rates with minimal viscosity increase
Provide a thin, pliable, easily removed filter cake to minimize formation damage and facilitates cleanup during completion
Flocculate dispersed drill cuttings in clear water drilling

Advantages
Temperatures stable up to 300A F and provides filtration control at temperatures >250A F
Effective with fast drilling non-dispersed systems
Works in high-density brines, e.g., CaCl2, CaBr2 and ZnBr2
Acid Soluble
