PAC ULV (Ultra Low Viscosity PAC, Minimum Viscosity PAC) extends filtrate control into heavy, high-solids and weighted brine systems where even LV-grade viscosity contribution is too much. Its tightly controlled chain length achieves fluid loss reduction with a near-invisible rheological footprint — the specialist’s grade for rheology-critical, high-density fluids, making it an ideal Heavy Brine Filtrate Reducer.
