What is partially hydrolyzed polyacrylamide (PHPA) based high molecular weight drilling polymer?

Partially Hydrolyzed Polyacrylamide (PHPA) based high molecular weight drilling polymer for use in controlling of fluid loss and increasing drilling mud viscosity and removal of colloidal from deep drilling foundations such as diaphragm walls, piling concretes, etc.

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.

Are PHPA drilling polymers toxic?

Key Features and Benefits: Chemtex's PHPA Drilling Polymers when tested for its toxicity level, were found eco-friendly and when compared to its contemporaries such as Bentonites (Al2H2O6Si). They may not be hazardous to soil but is highly toxic to aquatic life and hence do not find its use in sites beside water bodies.

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.

Does ChemTex drill polymer cause marine toxicity?

Chemtex's Drilling Polymer has neither marine toxicity nor does it affect farming land if disposed. Moreover, it is used at only one-tenth concentration of bentonite and can be easily broken down with normal bleaching solution.
