A novel molecularly engineered deep eutectic surfactant from a Gemini ionic liquid and methylurea for EOR utilization: a joint experimental and computational study
Abstract
at 328.2 K, demonstrating superior performance compared with its individual precursors or their simple mixture. The experimental IFT data were successfully reproduced using the Frumkin adsorption model with reasonable parameter fitting. Moreover, the DESU promoted the formation of stable water-in-oil emulsions, achieving a maximum emulsion index of 65%, and altered the surface wettability of a quartz plate from oil-wet to water-wet, as evidenced by a contact angle change from 137° to 41°. Overall, these results demonstrate that the designed DESU exhibits remarkable interfacial properties and provides multiple advantages for enhancing the efficiency of EOR processes.
