A pore-scale model for permeable biofilm: numerical simulations and laboratory experiments

Selectively plugging: The use of microorganisms to form biofilms in higher permeable regions of the reservoir to divert water flow to lower permeable regions to improve oil recovery. Motivation: Understanding the mechanism involved in the formation of biofilms is important to control their formation. Objective: To develop, implement, and calibrate an accurate numerical simula- tor for biofilm formation considering:   The biofilm as a porous medium with permeability k and porosity  tw.   4 biofilm components: water (w), EPS (e), active (a) & dead bacteria (d).
