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.
