High Viscosity Polyanionic Cellulose (PAC-HV)

High Viscosity Polyanionic Cellulose (PAC-HV)

As a high-molecular weight polyanionic cellulose polymer with high purity, Landoil PAC-HV will act as a highly effective filtration control additive in fresh, hard, and saline water, with regard to reducing filtration rate, increasing viscosity, and encapsulation of clays.

Applications

Landoil PAC-HV is a multifunctional additive. It performs as an excellent viscosifier that increases viscosity to promote better hole cleaning, and forms a protective colloid which inhibits the hydration of water sensitive formations and encourages borehole stability through filtration control. Landoil PAC-HV will enhance the lubricating properties of the fluid, and can be added to foam to improve cuttings transportation. A Bentonite-based fluid system can be enhanced by adding Landoil PAC-HV, which is also compatible with the majority of polymer lubricants. Addition rates can be changed to adapt to specific applications.

Advantages Economical Effective in low concentrations Rapidly increasing viscosity Reducing fluid loss Improving shale control Natural polymer-based product, minimal environmental impact Extending service life of foam or stiff foam in air drilling High degree of substitution (DS), excellent high temperature resistance and salt tolerance Compliant with API 13A standard Physical Properties
