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.

Why is PHPA polymer used in drilling mud?

PHPA polymer is used in drilling mud due to its ability to remove drilled logs from the well wall. The molecule is composed of identical and hydrophilic monomers that are dissolved in long fibers like water, which is a property that makes this polymer effective in drilling mud.

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.

Can PHPA be used in drilling fluid?

PHPA (Polyanhydric Polyisocyanide) is used as a material to increase viscosity, reduce friction, and coagulate in drilling fluids. It can also be used to block fine slits in the formation by coating the surface with the polymer. These features can be utilized in both fresh and saline waters.

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.
