Description
CMC-HVT is a high-molecular-weight, high-viscosity, dispersible Carboxymethyl Cellulose fluid loss additive designed to provide viscosity and reduce API filtration rate in water-based drilling fluids.
Application
Carboxymethyl Methyl Cellulose High Viscosity CMC-HVT is a high-viscosity and cost-effective additive used to reduce API filtration rate of any kind of water-based drilling fluids, from fresh water to saturated salt water. It is suited for water-loss and rheological control in low-solids mud and is a highly efficient viscosity in all other mud.
Advantage
1. Widely available and low-cost polymer for fluid loss control.
2. Effective at providing filtration control in most water-based drilling fluids.
3. Effective in low concentrations.
4. It is non-Toxic.
5. It is not subject to bacterial fermentation and calcium contamination.
6. Can be used in most water-based fluid systems.
7. Increases viscosity.
