Carboxy Methyl Cellulose
Carboxy Methyl Cellulose is a high viscosity, high molecular weight dispersible fluid loss additive designed to provide viscosity and reduce API filtration rate to water-based drilling fluids.
Application:
CMC is a cost-effective additive used to reduce API filtration rate of many water-based drilling fluids from freshwater to saturate saltwater. It is suited for water-loss and rheological control in low-solids mud and is a highly efficient Viscosifier in all other mud.
Common Name: Carboxymethyl Cellulose (High Viscosity)
Advantages:
- Widely available and low-cost polymer for fluid Loss control
- It is an effective at providing filtration control in most water-based drilling fluids.
- It is effective in low concentrations.
- It is Non-Toxic.
- It is not subjected to bacterial fermentation and calcium contamination.
- Can be used in most water-based Fluid systems.
- Increases viscosity.
