Abstract: Microbial enhanced oil recovery remains the most environmental friendly, cost effective recovery technique in oil production, particularly for wellbore stimulation. This research investigates the effects of microbial growth rate, microbial and nutrient concentrations for well stimulation purposes. A representative model incorporating microbial concentration, its growth rate and skin factor is developed, validated and discussed. An explicit formulation which poses a solution to the equation for the model is used to describe the reservoir pressure responses. It is observed through plots of reservoir pressure against reference distances that flow and production rates improved as a result of an improved BHP when the microbial parameters were incorporated to the fluid transport equation at same injection rates and same reservoir parameters. The trend followed by the pressure profile plots correlates with that expected of a well stimulation pressure profile.
