Product Description

Product Description

SHARKCMC^® H filtration control additive 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. SHARKCMC^® 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. SHARKCMC^® H treated systems should be pretreated with either sodium bicarbonate or possibly citric acid prior to drilling cement.

Applications/Functions

• Controls filtration rates in freshwater and seawater mud systems
• Deflocculates some seawater muds when used in low concentrations

Advantages

• Stable at temperature up to 250°F
• Widely available and an economic source of polymer fluid-loss control
• Concentrated chemical, very effective at small treatment levels

Typical Properties

• Appearance: Off-white powder
• Specific gravity: 1.59
• pH (5% aqueous solution): 9-11

Recommended Treatment

• Freshwater: 0.5-1.5 ppb
• Seawater:  2-3 ppb
• Add slowly through a mixing hopper at a rate of 10-20 min/sack

Package

• 25 KG SACK
