Description
SUPERNITE®C is a top-quality causticized lignite with a high content of humic acids. It is an excellent cost-effective viscosity and filtration control agent for use in all water-based drilling fluid systems in HTHP downhole environment.
SUPERNITE®C is a very effective rheology control agent in both high and low pH mud systems. It is partially water-soluble and is heat stable above 400F (204C).
SUPERNITE®C can be used in all types of water-based muds and oil-in-water emulsions. It is tolerant to most common contaminants and works well at high hardness and wide range of pH.
Applications/Functions
· HTHP fluid loss and rheology control
· forms an impermeable filter cake, prevents fluid and filtrate invasion
· stabilizes rheological properties at high temperatures, prevents gelation
Advantages
· doesn’t require additional alkaline material to function properly
· resistant to most common contaminants
· improves filter cake quality
