EvoVis® S high-temperature viscosifier is a water-soluble polymer designed to provide superior thermal stability in all types of water-based drilling fluids.
- Maintains solubility
- Extremely tolerable to pH changes
- Improves carrying capacity of fluids
- Hydrates rapidly in water-based fluids
EvoVis S viscosifier can be used in all types of water-based drilling fluids, including those with high salt and calcium content. This product functions at any salinity and is particularly suited for use in high-temperature environments exceeding 240°F (116°C).
General treatment recommendations of EvoVis S viscosifier can range from 0.5-2.0 lb/bbl, based on salinity. Initial treatments are best determined by lab evaluation. This product can be mixed directly through the hopper.
