FEATURES & BENEFITS
Provide filtration control and stabilizes the rheological properties of most water base
drilling fluids. It has a strong affinity for decal surfaces and will restrict their hydration
and dispersion. Not susceptible to bacterial degradation. Moreover, it has high tolerance
to divalent ions and is effective over a wide pH range.
PACKING
25kg in multiwall paper sack.
APPLICATIONS For maintaining filtration drilling, the optimal concentrations are 0.25-3.0lb/bbl (0.7-8.6kg/m3).
