| N-Dril |
 |
N-DRIL, modified starch, can be used to ensure filtration control in water-based fluids with minimum viscosity build-up.
N-DRIL exhibits excellent stability against bacterial fermentation and contains no toxic preservatives.
*Applications/Functions: Control filtration in fresh water or electrolyte-based drilling fluid systems at temperatures up to 300'F(149'C), Provide filtration control of drilling fluids in environmentally-sensitive areas
*Advantages: Provides filtration control with a minimal increase in viscosity, Minimizes the dispersion of shale and clay cuttings, Does not require a biocide and does not ferment, Effective in fresh water, sea water, salt water, and saturated salt water drilling fluids, Can be used efficiently in gypsum-treated and lime systems, Maintains filtration control when contaminated by brine water flows, salt, gypsum, anhydride, cement, or other contaminants |
