Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.
