CMC-LV is a technical-grade low-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-L is used in high-viscosity, high solids or heavily weighted fluids and produces only slight increases in viscosity. Subject to bacterial degradation, a biocide should be used to prevent fermentation. CMC-L treated systems should be pretreated with either sodium bicarbonate or possibly citric acid prior to drilling cement.
Control filtration rates with minimal viscosity increase in freshwater and seawater mud systems
Deflocculate some seawater muds when used in low concentrations
Temperatures stable up to 250°F
Widely available and an economic source of polymer fluid-loss control
Concentrated chemical, very effective at small treatment levels
pH (5% aqueous solution)
Freshwater: 0.5-1.5 ppb
Seawater: 2-3 ppb
Add slowly through a mixing hopper at a rate of 10-20 min/sack
