Product Description

Product Description

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

Applications/Functions

 

• Control filtration rates with minimal viscosity increase in freshwater and seawater mud systems
• Deflocculate some seawater muds when used in low concentrations

Advantages

 

• 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

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
