Polyanionic Cellulose oildrilling
Polyanionic Cellulose
Overview
Polyanionic Cellulose can be used in drilling fluid, fixing fluid and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer, and rheology controller; in fixing fluid, it is used to control fluid viscosity, suspend heavy objects, and avoid fluid loss; in fracturing fluid, it is used to carry stuffing and avoid fluid loss. It meets API international standard.

Sodium Carboxymethyl Cellulose
Overview
Sodium Carboxymethyl Cellulose is a high quality water soluble cellulose derivative. It has good thermal-stability and high salt resistance. It is soluble in water to form thick liquid, and widely used in water-base drilling fluid so as to enhance the drilling fluid viscosity and control the fluid loss.
