Final oil recovery efficiency can reach 60.13% with a 0.5 PV injection volume, showing significant oil recovery improvements.
The surfactant-inclusion system exhibits ultralow interfacial tension and enhanced compatibility with cores of permeability around 200 × 10–3 μm2.
In heterogeneous formations, the system increases fluid resistance and redirects flow towards low-permeability areas, achieving a 23.85% incremental recovery.
Mechanistically, enhanced oil recovery is driven by improved wettability alteration and reduced interfacial tension, optimizing crude oil extraction.
