Physicochemical properties of JS@GO nanofluid and its potential in enhanced oil recovery

Employing nanofluid flooding as an advanced enhanced oil recovery (EOR) technique has emerged as a groundbreaking approach for the extraction of residual hydrocarbons from increasingly depleted reservoirs. The innovative utilization of nanocomposites, specifically Janus SiO2 (JS) particles amalgamated with graphene oxide (GO), constitutes the focus of this research. We elucidate how this novel JS@GO nanocomposite enhances oil displacement through its exemplary interfacial activity, substantiated by various empirical evaluations such as contact angle and interfacial tension tests. Moreover, core flooding experiments corroborate the nanocomposite's superior efficiency in augmenting oil recovery vis-a-vis traditional methodologies, which was due to the improvement of both emulsifying ability and amphiphilicity. The results of this research underscore the considerable promise the JS@GO nanofluid holds for future EOR applications, providing a compelling alternative for revitalizing oil production from heretofore unyielding reservoirs.
