SOLUBILITY IN WATER @ 20 0C
Granules, off white powder
1.5 - 1.7
CMC EHV is primarily used as viscosifier in freshwater and brackish water systems during surface and intermediate drilling. CMC EHV will also reduce the fluid loss.
Cost effective viscosifier.
Effective in low concentrations.
Not subjected to bacterial fermentation.
Treatments for freshwater and seawater fluids are generally 0.5 - 4.0 lb/bbl (2.85 – 11.4 kg/m3). Actual concentrations required will depend on the type of mud system, salinity, temperature and properties desired.
Rapidly losses effectiveness with increase in salinity.
Temperature limit of @ 225 - 250 0F (107 - 121 0C).
Consult MSDS before use and use personal protective equipment as advised.
CMC EHV is available in 25 kg (55 lb) polyethylene bags. All materials are stored in a dry well ventilated area.
