Product: CMC-HV(carboxy methyl cellulose high viscosity)
Application:
High viscosity CMC is used as thickener and low viscosity CMC as agent of lowering the filtration lost in the preparation of drilling liquid. It is beneficial to use CMC during drilling under complex stratum and off shore. It can increase the oil production yield. CMC-HV is sodium carboxy methyl cellulose, used as the filtration control agent and viscosifier in various types of water based muds ranging from fresh water to the salt water, particularly with higher mud weight and it is no-toxic. CMC-HV can increase the viscosity of the mud.
