What is the use of polyacrylamide in oil drilling?

For oil drilling, liquid or powder partially-hydrolyzed polyacrylamide is used as additives to water based drilling mud to provide a lubricating film and reduce friction at the drill bit, impart stability to shale and clay and increase viscosity [ 1, 22, 26 ].

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.

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.

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.

How does drilling polymer work?

Use of Drilling Polymer effectively flocculates drill cutting, high and low quality clay, driving them out of the well, inhibiting their dispersion.

Why should you use ChemTex based drilling polymer?

Hence its usage on drilling site is proven economical and moreover, if incorporated with advanced technology, finds extensive utilization even during slim-hole drilling in coal field, geologic engineering, metallurgy and non-ferrous geology. Advantages of Chemtex's PHPA based Drilling Polymer
