PHPA (Partially Hydrolyzed Polyacrylamide)
This product has been discontinued and removed from our shelves.
PHPA, namely partially hydrolyzed polyacrylamide, is a high-molecular-weight oilfield chemical that is specially treated and fabricated for all kinds of water-based drilling fluids, such as freshwater, seawater, saturated saltwater, KCl brine and other solids-free brines.
Function
This drilling fluid additive is adopted to provide shale inhibition and borehole stability. Aside from these, it also works as viscosifier, lubricant, flocculent, cuttings encapsulator,bentonite extender and fluid loss controller.
