what is partially hydrolyzed polyacrylamide (phpa

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.

[PDF] Synthesis and evaluation of partially hydrolysed

High molecular weight (106) partially hydrolysed polyacrylamide (PHPA) has been prepared and its efficacy as viscosifier in water based drilling mud has been evaluated. When PHPA is added to bentonite mud system, it causes a viscosity hump indicating encapsulating effect. The breakdown point of the hump varies with the concentration of the solid mud and also with the molecular weight of the ...
