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.
APPLICATIONS
Application scenarios
- 01Viscosifying and rheology control in freshwater and saltwater muds
- 02Solids-free drilling fluids for reservoir-protection drilling
- 03Hole cleaning and cuttings suspension

USAGE
Usage
In freshwater drilling fluids, add 0.2%-0.4% by weight of the total mud. Add slowly with good agitation to avoid fisheyes, and adjust within the range to the required viscosity.
