Description of Oil Drilling Grade CMC & PAC
CMC & PAC can be used as fluid loss reducer or viscosifier in drilling fluids. The function of CMC is to reduce the fluid loss as much as possible through forming low permeability, flexible, thin and compact filtration cake on borehole wall. Used as thickening agent, suspension agent and plugging agent.
Our PAC-HV/LV (CMC oil drilling grade) and CMCHV/LV are advantageous because of their small dosage, high yield, anti-bacterial, good salt tolerance properties and convenient to use, reduction of fluid loss, and improvement of viscosity, flowing control and strong suspending capability, environmental friendly, non-toxic, harmless and odorless, and good liquidity, convenient to construction.
- CMCdrillingrate.
- polyanionic cellulose PACcan be used in fresh water to saline water drilling fluids.
