ABSTRACT: The development of a three-dimensional, three-phase, multicomponent numerical model to analyse the microbial transport and fluid flow phenomena in a microbe-flooded reservoir is presented. The multiphase flow equations are solved in multi cases and in three-dimensional frameworks following the implicit pressure explicit saturation (IMPES) procedure in which the solution of the bacteria transport equations is solved implicitly whereas the nutrient transport equation is solved explicitly. The MEOR model was incorporated into an existing chemical flooding simulator (UTCHEM). The simulation results showed that the sharp increase of pressure after the microbial flooding is caused by pore plugging and the production of biogenic gas. As the time increased and water flooding continued, the permeability recovered slightly with the declogging of microbes in the pore space, resulting in a decrease in pressure drop.
