Polyanionic cellulose is a substance with high temperature resistance and salt resistance, which finds application in drilling fluids. Its introduction into the aqueous phase of the drilling mud helps to reduce the filtration rate and provides an effective thickening function. This substance is often used as a viscosity regulator and a water loss reducing agent for all types of drilling fluids based on water. It also prevents the wetting and sliding of clay and alumina with water into the well, which prevents their erosion. Thanks to polyanion cellulose, the loss of pressure on the friction of the flow, which usually occurs during vertical and horizontal drilling, is reduced. In aqueous solutions, it shows resistance to contamination with calcium ions. The viscous-plastic properties of aqueous solutions of polyanionic cellulose allow it to be used to regulate the rheological properties of water-dispersion paints, adhesives and other systems containing water. There are two types of polyanion cellulose – PATS-NV (low-viscosity) and PATS-BB (high-viscosity).

Main functions:

√ Prevention of water loss by creating a film on the walls of the well.
√ Adjustment of drilling mud viscosity
√ Helps to prevent the destruction of the well wall due to the film formed by it
√ Helps to transport drilling mud to the surface and facilitates cleaning
√ Helps to thermally and bacterially stabilize drilling mud

The main area of use of chemical raw materials is oil and gas production processes.
Drilling, construction and repair of wells. Intensification of oil and gas production.
