Performance of a good‐emulsification‐oriented surfactant‐polymer system in emulsifying and recovering heavy oil

Energy Science & Engineering, 2020
Considering the significant importance of emulsification for heavy oil recovery, a good‐emulsification‐oriented (GEO) (rather than the conventional ultralow interfacial tension (IFT) oriented) surfactant‐polymer (SP) system was employed to remove heavy ...
