Polyanionic Cellulose

01 Overview

Low-viscosity polycationic cellulose exhibits excellent fluid loss control properties, whilst high-viscosity polycationic cellulose may serve as a viscosifier in water-based drilling fluids and low-density brines.

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.
