Description

Product Description
PAC LV is low-viscosity polyanionic cellulose (PAC) offered by our company, used as a fluid-loss control additive for drilling mud. PAC LV has low molecular weight which is essentially not a viscosifier.
Advantages：
Effective in controlling fluid loss
Resists attack from bacteria, requiring no preservatives or bactericide
Environmentally acceptable
Depending on water quality, provides viscosity
Functions at all ranges of pH levels in both dispersed and non‐dispersed fluids
Application Range and Method
When use, directly mixed into drilling fluid.
Recommend dosage：
Add (2 - 5 kg/m3) of PAC LV filtration control agent slowly through the mud hopper.
