Polyanionic Cellulose (PAC) is a water-soluble polymer derived from natural cellulose, primarily used in oil and gas drilling applications. It functions as a premium viscosities and fluid-loss control agent, improving drilling mud rheology, suspending drill cuttings, and maintaining wellbore stability under high-temperature and saline conditions.
It enhances the performance of drilling fluids by providing superior viscosity control, reducing fluid loss into porous formations, and improving lubrication during drilling operations. PAC is highly effective in both freshwater and saltwater systems, making it suitable for challenging drilling environments.
Its thermal stability and resistance to electrolytes ensure consistent performance even under harsh downhole conditions. Additionally, it helps improve drilling efficiency, protects formation integrity, and supports smoother and safer drilling operations.
