PAC
Product usage：
Low-viscosity PAC (PAC-LV): Acts as a fluid loss agent, effectively controlling fluid loss of drilling fluids with little effect on viscosity.High-viscosity PAC (PAC-HV): Functions as a viscosifier to increase drilling fluid viscosity, while also providing fluid loss control.
Seawater / saturated saltwater drilling fluids: Excellent salt resistance, enabling effective fluid loss control even in saturated saltwater systems.
Completion / workover fluids: Protects oil and gas formations, preventing damage to reservoirs from solid particles and filtrate.
Shale inhibition: Encapsulates drill cuttings, inhibits shale hydration and dispersion, and stabilizes the wellbore.

Product Description
Polyanionic cellulose (PAC) is an anionic water-soluble cellulose ether, used as a highly effective viscosifier and fluid loss additive inoilfield drilling fluids.It can significantly reduce mud cake permeability and improve flow pattern.
