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 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.

Why is polyacrylamide required to hybridise with nanoparticles?

However, there are limitations regarding the properties of polyacrylamide, which are thermal degradation, fluid loss, and others. Bored pile stability is also another concern. Therefore, polyacrylamide is required to hybridise with nanoparticles in the drilling system.

What is a bored pile in Malaysia?

In Malaysia, a support fluid or a full-length casing is used in the stabilisation of the excavation site, which is then followed by the formation of concrete casting known as a bored pile. Bentonite clay slurry has been chosen as a stabilising agent for numerous excavation projects in the world since the pioneering work of Veder in 1953.

Can hydrophobically modified polyacrylamide gel be used in high temperature drilling?
