Fenghong Company provides multiple high-cost-effective organic clay products for traditional diesel-based drilling fluids, covering fatty acid modification, cationic modification, and surface composite modification approaches, suitable for medium to high temperature (150~200°C) environments.

The products have good rheology regulation capabilities, significantly improving low shear gel value (AV), yield point to plastic viscosity ratio, and static to dynamic ratio, helping to prevent cuttings settlement and abnormal ECD rise, ensuring stable operation of drilling fluids under complex formations.

For drilling areas with higher environmental requirements, such as urban areas, freshwater blocks, or offshore platform operations, Fenghong Company has launched white oil-compatible rheology additives with better dispersibility and high shear viscosity control capabilities.

This type of product can operate stably at 170~200°C, especially compatible with ultra-low pour point mineral oils and refined base oil systems, with stronger fluidity, excellent compatibility, and convenient for building lightweight high-density systems.

For high-temperature drilling challenges such as ultra-deep wells and HPHT wells at 200~240°C, Fenghong Company has developed multiple high-temperature stable organic clay materials with excellent thermal shear stability and high-temperature colloidal structure maintenance capabilities.

The products can still maintain good yield point to plastic viscosity ratio and thixotropy under continuous high temperatures, reducing circulating pressure, improving wellbore cleaning efficiency, effectively reducing downhole complexity risks, suitable for typical difficult drilling formations such as deep shale, sandstone, and high-pressure salt-gypsum.
