What is polyacrylamide used for?

Hence, it is an earth-stabilising fluid that is designed for a variety of applications in the geo-construction industry such as tieback anchors, diaphragm walls, horizontal drilling, tunnelling, slurry trenching, drilled shafts/bored piles, and others. 6.1. Polyacrylamide in drilling technology

What is modified polyacrylamide drilling fluid?

Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.

What is drilling additive?

Drilling additive is a factor that affects the rheological performance of drilling fluid during operation. Previously, bentonite was frequently employed in water-based drilling fluid, especially for geotechnical usage. Bentonite has superior rheological properties that can support the bored pile foundation.

Can polyacrylamide be used for drilling?

However, polyacrylamide with high molecular weight can be a good candidate at lower concentrations to meet the drilling requirements. The viscosity of polyacrylamide at all concentrations decreases with increasing temperature, according to Magzoub et al. (2021).

What is the thermal conductivity of polyacrylamide based drilling fluid?

It showed thermal conductivity around 0.9 Wm −1 K −1 that have 84% improvement when compared to the bare polyacrylamide. Study of filtration and rheological properties in polyacrylamide-based drilling fluid using graphene oxide

Is polymer an alternative additive in water-based drilling?

Correspondingly, polymer is an alternative additive in water-based drilling as it is known as a rheological modifier, shale inhibitor, and fluid loss additive in drilling technology. There are many challenges related to the use of polymers in water-based drilling fluids.
