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.

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 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.

How do you mix PHPA?

Add PHPA in concentration of 0.7 to 4.3 kg/m³ (0.2 to1.5 lb/bbl) to any active system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer. Transportation of commodity name is not restricted by international regulatory agencies. Utilize normal precautions for employee protection when handling chemical products.
