CMC-HV (High-viscosity sodium carboxymethyl cellulose)

Introduction
CMC-H is a technical-grade high-viscosity sodium carboxymethyl cellulose used to reduce filtration in fresh water and seawater mud systems up to 250°F. It is less effective in brines and saltwater and is not generally recommended to be used if the salinity exceed 50,000 ppm.
CMC-H is used in low-viscosity or low-solids fluids and increase viscosity in addition to controlling fluid loss. Subject to bacterial degradation, a biocide should be used to prevent fermentation. CMC-H treated systems should be pretreated with either sodium bicarbonate or possibly citric acid prior to drilling cement.
