Abstract: Microbial injection in petroleum reservoirs for enhancing oil recovery has recently been an area of intensive study in the oil and gas industry. Before the application of this non-expensive, environmental friendly method of recovery is employed, the comprehension of its modus operandi is paramount, most essential being its movement and transport techniques through tortuous porous media in petroleum reservoirs. This study reveals the patented process of microbial transport through advection within a finite length reservoir by development and Simulation of a mathematical model which when validated with microbial and reservoir parameters, showed a great degree of similarity with an already established model. Simulation of these models presented a visual description of the longitudinal mixing process of dispersing microbes in the reservoir using the SIMULINK program.
