Pour Point Dispersant
Pour Point Dispersion (PPD) is a specialized drilling chemical additive designed to reduce the pour point of oil-based drilling fluids and prevent wax crystallization at low temperatures. It improves the flowability and pumpability of drilling fluids in cold environments and enhances stability during storage and transport.
PPD modifies wax crystal structures and prevents agglomeration, ensuring smooth circulation in deep wells, HPHT wells, and low-temperature drilling zones.
