FILREW 23

A high-temperature and salt-resistant filtration loss reducer, particularly effective in water-based systems. It is specially designed through a preferential selection of thermostable and salt-tolerant monomers. FILREW 23 boasts the advantages of superior shear resistance, salt resistance, imperviousness to high valent ions and thermal stability over conventional polymers.

Application

• High hydrolysis resistance – suitable for any water-based drilling muds from freshwater to saturated saltwater systems
  
• High temperature resistance of up to 180°C – suitable for ordinary wells, saltwater wells, high temperature well and offshore oilwells
  
• Used as viscosity builder, shearing potentiator and fluid loss additive in completion fluids
