To study the profound impact of reservoir characteristics on flow regime in two‐phase condition, the effect of saturation and capillary pressure (Pc–S) should be taken into consideration in the porous medium. The purpose of this extensive experimental investigation is to inject the foaming agent and nitrogen gas, which is produced by the foam generator after waterflooding in a fractured reservoir to select the best optimum scenario. It has been elaborated that nitrogen of lower density and lower compressibility would provide a secondary gas cap at the top of the cores which causes to mobilize more oil volume in the unswept zones. The rupturing of foam considerably influences this phenomenon in the high permeable layers that have led the oil of low permeable layers to be mobilized in the presence of nitrogen.
