PAC Oil Drilling Additive Filtrate Control

This video explains the main functions and practical uses of PAC-R, a modified polyanionic cellulosic polymer for oil drilling, in a clear, step-by-step format. You'll see how PAC-R provides effective filtration control in bentonite-based drilling fluids, improves borehole stability, and reduces filtrate loss in various drilling applications including HDD, water wells, and oil field operations.
