EvoTrol™ HT filtration control agent is a synthetic polymer designed to provide shale inhibition and fluid loss control in high-temperature, water-based drilling fluids. The product can be used in fresh or salt water to control fluid loss, build viscosity and protect hydratable solids from dispersion.
- Reduces potential for differential sticking
- Increases efficiency of solids control equipment
- Improves thermal stability of water-based drilling fluids
EvoTrol HT filtration control agent is non-fermenting and is highly effective in all types of water-based fluids. EvoTrol HT can be used for high-temperature fluid loss control and shale inhibition as it is thermally stable to 475°F (246°C).
General treatment recommendations of EvoTrol HT 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.
