Fractured reservoirs pose significant challenges for enhanced oil recovery (EOR) operations due to their complex structure and dual-porosity system. Conventional gas injection methods often result in low sweep efficiency because of early breakthrough through fractures. This study proposes a novel approach utilizing osmotic gas injection to create favorable pressure gradients, enhancing oil mobilization from the matrix to the fractures. A theoretical model is developed and a numerical simulation framework is suggested to evaluate the effectiveness of this technique. The outcomes of this research could introduce an innovative, cost-effective method to optimize hydrocarbon recovery from fractured systems.
