Introduction
———

DYPAN-HT is a high-performance polymer tackifier / viscosifier for drilling fluids, designed to provide viscosity enhancement, suspension support, and fluid-loss control support under demanding conditions. It is produced via inverse-emulsion polymerization and is suitable for high-salinity drilling fluids (e.g., KCl, NaCl, CaCl₂ systems). The product is designed for high-temperature operations up to 180°C (356°F) and demonstrates strong salt-brine performance, including viscosity retention in saturated NaCl brine after 180°C (356°F) / 16 h.

Applications / Functions
—————

• Provides viscosity build and improves suspension capacity, especially in clay-free drilling fluids

• Supports weighting operations with limestone powder and barite for higher-density systems

• Helps improve HTHP filtration performance and supports fluid stability in challenging drilling intervals

• Compatible with common saline systems such as KCl, NaCl, and CaCl₂

Advantages
———

• Brine compatible: performance maintained in high-salinity environments

• Enhances carrying capacity and improves solids suspension in clay-free systems

• Emulsion form supports practical handling and field mixing

Recommended Treatment
