Polyanionic cellulose (PAC)
Polyanionic cellulose (PAC) is a water-soluble derivatives of cellulose ethers made of natural cellulose processed by chemical modification. It is an important water-soluble cellulose ether with good heat stability and salt resistance. The mud fluid prepared by PAC offers good water loss reduction, inhibition and high temperature resistance. It is widely used in oil drilling, especially salt water wells and offshore oil drilling.
