Description
SUPERNITE® is a naturally occurring material used to reduce fluid loss and deflocculate water-based muds.
SUPERNITE® is partially soluble additive which provides thin, low-permeability filter-cake and acts as a secondary deflocculant and fluid loss control agent in high-temperature applications. It performs exceptionally well in dispersed mud systems and has a synergistic effect with RESITEMP® additive.
Applications/Functions
· provides improved HTHP filtration control
· reduces viscosity and gel strengths
· extends the temperature stability of water-based muds
· improves filter-cake quality by reducing its thickness and permeability
Advantages
· stabilizes rheological properties
· resistant to contaminants
· compatible with all types of water-based drilling fluids
Recommended treatment
It is recommended to pre-solubilize SUPERNITE® with caustic soda (4:1) for best results. Normal treatments of SUPERNITE® range from 1 to 8 lb/bbl (2.85 to 22.8 kg/m3). Due to their low pH, SUPERNITE® treatments require additional caustic soda or an alternative alkaline material, to maintain a consistent pH. A normal ratio is one sack of caustic soda for every four sacks of SUPERNITE®. In high-salinity systems, it is preferable to premix the SUPERNITE® in medium-pH freshwater to enhance dispersibility then add the premix to the active system. It is most effective in mud systems with an alkaline pH in the range of 9 to 11.
