Microbially induced calcite precipitation (MICP) is a new and sustainable leakage prevention technology which utilizes biochemical processes to create barriers by calcite cementation. We describe a field-scale model of MICP technology including transport of limiting components in the injected solutions (bacteria, substrate, and urea), bacterial attachment, biomass detachment, death of bacteria, formation of biofilm, usage of urea, and production of calcite, modifying the rock porosity and hence the effective permeability. We study diverse injection strategies to prevent leakage of CO2 in two set of reservoir properties.
