Description:CMC (technical grade) is a dispersible, sodium carboxymethyl cellulose, fluid-loss reducing additive supplied in three grades: low viscosity, high viscosity and extra-high viscosity. CMC additive can be used in freshwater and seawater mud systems,keeps properties under high temperature faced in geothermal drilling made according to API 13 a and EN ISO 13500 standards.
Applications:CMC technical-grade additive is used as a fluid-loss reducing additive in freshwater and seawater muds. It is less effective in brines and saltwater and is not generally recommended to be used if the salinity ezceeds 50,000 ppm. CMC Lo Vis tech-grade additive is used in high-viscosity, high-solids or heavily weighted fluids and produces only slight increases in viscosity. CMC Hi Vis and Extra Hi Vis tech-grade additives are used in low-viscosity or low-solids fluids and increase viscosity in addition to controlling fluid loss.
ADVANTAGES and LIMITATIONS:
- Widely available and an economic source of polymer fluid-loss control
- Concentrated chemical, very effective at small treatment levels
- Can be used in most water-base drilling fluids
- Subject to bacterial degradation, a biocide should be used to prevent fermentation
- Not utilized in high-salinity fluids that exceed 50,000 ppm
- Not tolerant of high-pH and high-calcium-ion conditions in combination
