Six surfactant (S) and surfactant-polymer (SP) systems (with different interfacial tension (IFT) and emulsification behaviors) were compared for their ability to recover heavy oil. Attention is paid to their emulsifying capacity, emulsion stability, heavy-oil viscosity reduction, microscopic displacement, and final oil recovery. It is found that the advantages in emulsion stability, oil-viscosity reduction, and moreenlarged sweep volume (observed in microscopic displacements), make the non-ultra-low IFT systems more powerful in recovering heavy oil compared to other ultra-low-IFT systems, indicating the dominant role of emulsion stability over ultra-low-IFT for SP systems when enhancing heavy oil (657.0 mPa s) recovery.
