A Multiphase and Multicomponent Model Considering Molecular Diffusion for Simulating Shale Oil Reservoirs With Complex Fracture Networks

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Molecular diffusion is a critical mechanism of enhance oil recovery (EOR) in developing shale oil reservoir by huff “n” puff. The ultra‐low permeability lead to the accumulation of injected gas within the complex fracture networks (CFNs), thereby, enhancing concentration gradient and mass transfer by molecular diffusion between the CFNs and matrix.
