What is Partially Hydrolyzed Polyacrylamide (PHPA
Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability. PHPA can be used in mud systems varying from low solids to weighted muds systems utilizing fresh or saltwater.

Partially Hydrolyzed Polyacrylamide (PHPA) Mud Systems
For exploration and development drilling of deepwater prospects in the Gulf of Mexico, operators have primarily utilized a high salt (20 percent w/w), partially hydrolyzed polyacrylamide (PHPA) mud system. This system has been used for many years as one of the most inhibitive water-based mud systems commercially available to the industry.
