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.

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.

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 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.

What is PHPA used for?

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. It functions as an inhibitor by coating or encapsulating formation & cuttings. It also restricts the interaction of water Hydratable & dispersible shale’s.

Which is the most popular drilling polymer for oilfield industry?

PARTIALLY HYDROLYSED POLYARYLAMIDE (PHPA) manufactured by GDFCL at its ISO Certified manufacturing Facility in Gujarat, one of the most Popular Drilling Polymers for the Oilfield Industry PHPA is a co-polymer of anionic character and high molecular weight.
