Can PHPA polymer be used as Vis-cosifier in drilling mud?

These studies suggest that PHPA polymer can be applied as vis- cosifier in drilling mud at and below 120°C. But the high value of fluid loss indicates that PHPA polymer requires fluid loss additive for successful application.

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.

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.

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.

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.
