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 is a partially hydrolysed co-polymer of acrylamide of high molecular weight. It is used in low solids and clear water drilling fluids on its own or with polyglycols and potassium chloride salt to give a high degree of shale encapsulation. PHPA is effective in fresh and salt water drilling fluids, minimizing the build up of solids in

The drilling mud also starts to separate out into two distinct components in without polymer, PAC-L, and PHPA test tubes. The water phase from the drilling mud gathered between the lighter crude and the denser drilling mud system. On the other hand, the biopolymers such as sodium alginate and pure-bore demonstrate stability in their appearances.
