Description
CMC-LVT is a low-viscosity, technical-grade, dispersible Carboxymethyl Cellulose fluid loss additive designed to reduce API filtration rate with minimum increase in viscosity in water based drilling fluids.
Application
CMC-LVT is a cost-effective additive used as a fluid loss reducer in fresh water and brackish water systems. It is used to control fluid loss in dispersed and non-dispersed drilling fluids.
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.
