[Display omitted] •A novel viscoelastic N2 foam for chemical enhanced oil recovery was developed.•Oil recovery efficiency of N2 foam was evaluated in Xinjiang Oilfield conditions.•The mechanism of N2 foam stability was explained by the viscoelasticity theory. A novel viscoelastic N2 foam (0.12% sodi...
