High Viscosity Sodium Carboxymethyl Cellulose
Product Description
CMC HV is a Technical Grade High Viscosity Sodium Carboxymethyl Cellulose which used for reducing fluid loss with supplementary increasing viscosity. Specially suitable for low-solid muds. It meets the drilling industry standards API Spec 13A Section 9 and OCMA DFCP-2.
  • Economic and effective API fluid loss reducer
  • Providing shale inhibition
  • Helping reducing friction pressure and builds a protective colloid on the surface of the drilling well wall
  • Compatible with other drilling fluid additives
  • Resists attack from bacteria, requiring no preservatives or bactericide
  • Environmentally acceptable
Application Range and Method:
CMC HV should be added to the solution by using high speed conventional mixers at a uniform rate and slowly in order to avoid lumping or fish eye formation and delayed dispersion.

Recommend dosage:
Add (0.5 – 2 lb/bbl) of CMC HV filtration control agent slowly through the mud hopper.
