FC-FR200S Fluid loss Control additives
• FC-FR200S, polymerized with AMPS as the main monomer, plays role of controlling fluid loss in drilling fluid.
• FC-FR200S, keep good fluid loss control performance in the range of normal temperature to 200℃;
• FC-FR200S, which has good compatibility with other drilling fluid rheology regulators, can work cooperatively with other rheology regulators to improve the suspension performance of drilling fluid under high temperature;
• FC-FR200S can effectively play role of controlling fluid loss in calcium salt and other high salinity brine drilling fluids;
