CMC is a dispersible, sodium carboxymethyl cellulose, fluid loss reducing additive supplied in three grades: LV, HV and EHV.

Common Name - Carboxymethyl cellulose (CMC)CMC Low Vis techgrade additive is used in highviscosity, highsolids or heavily weighted fluids and produces only slight increases in viscosity.Fresh & salt water drilling fluid performance is evaluated acc to OCMA DFCP-2.CMC High Vis and Extra Hi Vis techgrade additives are used in lowviscosity or lowsolids fluids and increase viscosity in addition to controlling fluid loss.  Design for use in fresh & slat water mud. Performance evaluated acc. To OCMA method DFCP-7.
