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 modified polyacrylamide be used in drilling technology?

Recent advances of modified polyacrylamide in drilling technology. J. Pet. Sci. Eng. 215, 110566 (2022). Hripko, R., Vajihinejad, V., LopesMotta, F. & Soares, J. B. P. Enhanced flocculation of oil sands mature fine tailings using hydrophobically modified polyacrylamide copolymers. Glob. Chall. 2, 1700135 (2018).

Can cationic polyacrylamide be used for oily wastewater treatment?

Zhao C, Zheng H, Gao B, Liu Y, Zhai J, Zhang S, Xu B (2018) Ultrasound-initiated synthesis of cationic polyacrylamide for oily wastewater treatment: Enhanced interaction between the flocculant and contaminants.

Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?

Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.

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.
