Chemical flooding is one of a promising method to be used for enhanced oil recovery. Surfactants are commonly used in improving oil recovery by lowering interfacial tension between oil and brine. The addition of Aluminosilicate into mixtures of anionic (SAE) - nonionic (FEO) surfactants improves water wetness on rock surface area, promoting wettability alteration toward water-wet. It is a phenomenon that potentially aids Enhanced oil recovery. This study conducted various experiments, including interfacial tension measurements between oil and brine using a spinning drop tensiometer, contact angle measurements using an optical tensiometer between a surfactant-NPs-brine solution and the Berea core, spontaneous imbibition, and coreflooding tests. It was summarized that the Aluminosilicate NPs could potentially improve the performance of the SAE and FEO surfactants for Enhanced Oil Recovery by supporting positive effects on increasing water wetness on rock surface of all the surfactant mixture combinations. However, the interfacial tension was lowered by NPs only for a mixture with 1:2 composition (between SAE and FEO). Spontaneous imbibition and coreflooding tests showed that oil recovery was increased by adding NPs in the surfactant mixture with 1:2 composition (between SAE and FEO).
