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.

Is PHPA a water soluble polymer?

PHPA is a co-polymer of anionic character and high molecular weight. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, Viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems.

What is PHPA (powder form)?

PHPA (powder form) is a readily dispersible additive designed to provide cuttings encapsulation and shale stabilization in freshwater to saltwater drilling fluids ranging from low solids to weighted muds.

Which drilling fluid is compatible with PHPA?

It is compatible with most of the drilling fluid products, biopolymers, PAC, CMC. It maintains borehole stability by preventing shale swelling and erosion. PHPA maintains viscosity in solid free drilling fluid. As a Bentonite extender in low solids non-dispersed mud, it can be used along with small addition of Bentonite to suspend weight material.

What is PHPA mud?

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. We have several grades to offer to meet our client’s need with variants.

How does PHPA work?

PHPA is formulated for easy mixing with improved dispersion to eliminate "fish eyes", which occurs when mixing either large quantities rapidly or mixing high polymer concentrations where good mixing equipment is unavailable. PHPA acts as a viscosifier, friction reducer, and flocculants, while also providing some fluid-loss control.
