| DN - 91 |
 |
DN-91, a modified and bacterially stabilized potato starch, provides filtration control with minimum viscosity buildup in water-based drilling fluids.
Through its coating mechanism, DN-91 reduces dispersion of clay particles and stabilizes reactive formations.
*Applications/Functions: Lower filtration rates in water-based drilling fluid systems, Improve borehole stability.
*Advantages: Maintains filtration control without detrimental viscosity increase, Effective with fast drilling nondispersed systems, Decreases clay dispersion |
