WBM(Water-Based Mud) Viscosifier & Filtration Control Agent
Product introduction
UBDrill-121 is a premium water-based drilling fluid viscosifier and filtration control agent designed for oilfield drilling applications. Formulated with acrylamide–acrylic acid copolymer and fine chemical materials, it delivers excellent rheology modification, filtration reduction, flocculation, and shale encapsulation performance.
The product provides strong salt resistance, calcium tolerance, and temperature stability, making it suitable for a wide range of water-based mud systems. UBDrill-121 helps improve drilling fluid carrying capacity, stabilize wellbores, and minimize formation damage during drilling operations.
