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).

Can polyacrylamide/clay nanocomposite be used as drilling fluid additive?

The troublesome shale formations need special formulation of drilling fluids having high shale inhibition characteristics to mitigate wellbore instability problems. In the present study, polyacrylamide/clay nanocomposite (PANC) was synthesized and used as drilling fluid additive.

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

Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling J. Mol. Liq., 325 ( 2021), p. 115155, 10.1016/j.molliq.2020.115155 Rheological properties of bentonite-free water-based drilling fluids with novel polymer viscosifier J. Petrol. Sci.

How can alumina/polyacrylamide nanocomposite improve the viscosity of drilling fluid?

Alizadeh et al. (2015) improved the polyacrylamide by synthesising alumina/polyacrylamide nanocomposite through solution polymerisation. As a result, the viscosity of the drilling fluid was more than 300 cP for freshwater mud at 4 wt% and about 100 cP for saltwater mud at 2 wt%, respectively.

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

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.
