Abstract: Different transport mechanisms occur within the subsurface region. To have a vast comprehension of these transport modes, researchers, scientists, scholars etc. are charged with the responsibility of providing concrete answers to lingering subsurface mass transfer questions. In this study, the prediction of diffusion rates of biogenic gases for a MEOR subjected core is investigated using a developed predictive model, which when compared to results from experiments conducted showed a great level of precision. The 50 -50 mixtures of both microbes for the MEOR investigation were also found to reduce the formation permeability and heavy crude viscosity, all of which constitute mobility improvement techniques.
