Viscosifiers & Rheology Modifiers
Viscosifier 80A-51
80A-51
80A-51 is a polymeric viscosifier with strong shear-thinning behavior that rapidly builds viscosity and optimizes rheology for cuttings suspension and transport. Compared with hydrolyzed polyacrylamide it provides better encapsulation and shale stabilization, and it is especially advantageous in solids-free fluids where formation damage must be avoided.
