It is a polymer of high molelcular weight and high viscosity grade. It is a long chain polymer.
Application
It is a viscosifier and fluid loss control agent and is used in all water based muds ranging from fresh water to saturated salt water.
COMMON NAME - POLYANIONIC CELLULOSE (PAC-RG)
Advantages
It is readily dispersible in all water based muds.
It provides viscosity and controls fluid loss.
It can be used to produce ultra low solid drilling muds for better rate of drilling.
