Carboxymethylcellulose (CMC)
Description of product
Carboxymethylcellulose (CMC) is a water-soluble, cellulose-derived polymer used extensively in various industrial applications, including the oil and gas industry. It functions as a viscosifier, fluid-loss control agent, and stabilizer in drilling fluids. CMC enhances the rheological properties of drilling fluids, ensuring efficient drilling operations and reducing formation damage.
Applications:
- Drilling Fluids: Acts as a viscosifier and filtration control agent, preventing excessive fluid loss into permeable formations.
- Cementing: Stabilizes cement slurries, improving pumpability and strength.
- Completion Fluids: Reduces fluid loss and prevents formation damage during well completion.
- Other Industries: Used in food, pharmaceuticals, and cosmetics as a thickener, stabilizer, or binder.
