WebThe complex trade-off between the effects of biosurfactant generation and biofilm growth has been a challenge for successful simulation and field-scale implementation of microbial-enhanced oil recovery (MEOR). In this work, a two-phase, two-dimensional MEOR model is developed, including effects from interfacial tension, porosity and permeability reduction.
