Water Based Filtration Reducer
FC-FR200S water based filtration reducer is a high-performance polymer fluid loss additive, formulated as a direct alternative to DRISTEMP for harsh water-based mud applications. It's copolymerized from AMPS/NN and complementary anti-salt monomers.
Built-in hydrolysis-resistant molecular chains boost thermal stability up to 230°C, while abundant -CONH2, -SO3H and -COOH functional groups bind free water tightly to form compact filter cakes and cut fluid loss. This powder mixes seamlessly with all standard water-based mud additives without disrupting mud rheology.
Real-World Drilling Benefits
- Reliable filtration control across fresh water, calcium-rich and high-salinity brine mud systems
- Maintains stable performance after long-term aging at extreme downhole heat, max working temp hits 230°C
- Works alongside other mud rheology modifiers to boost solid suspension under high temperature
- Versatile formula compatible with nearly all conventional water-based drilling fluid designs
