PAC LV
Description
PAC LV is a premium grade purified low viscosity, high molecular weight, Polyanionic Cellulose polymer designed to reduce API filtration rate to water based drilling fluids where additional viscosity is not needed or desired.
|
Application & Features
PAC LV is a cost-effective additive to reduce API filtration rate of many water based drilling fluids including freshwater, seawater, saturated saltwater and solids-laden fluids, dispersed and non-dispersed, weighted and un-weighted fluids, flocculated muds and contaminated systems.
PAC LV stabilizes viscosity to improve rheology, thins and deflocculates solids-laden systems without dispersing clays.
PAC LV is effective over a wide range of pH environments. It improves filtercake quality, thins and toughens wall cake, increase filtercake lubricity.
