FILREW 23

a high-temperature and salt-resistant filtration loss reducer, particularly effective in water-based systems. It is a free-radical polymerized product specially designed through a preferential selection of thermostable and salt-tolerant monomers such as acrylamide, AMPS, acrylic acid etc. 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
