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.

What happens when PHPA is added to bentonite mud?

When PHPA is added to bentonite mud, it causes a viscosity hump indicating encapsulating effect. The encap- sulating effect is influenced by the concentration of bentonite and molecular weight of PHPA. In the formulated mud PAC is found to be more compatible with PHPA mud system than CMC as fluid loss reducing agent.

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.

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.

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.

Why is PHPA a good drilling fluid?

High viscosity of this drilling fluid helps in better removal of cuttings from bore hole. It is resistant to bacterial fermentation. PHPA is packed in 25kg/50 Lbs (22.68 Kg) Sacks. Private Labeling and customized packaging is also available on request
