Advantages：
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.
CMC-HV is available in 25 kg multi-ply paper sacks, palletized as 40 sacks per pallet.
