Practical approaches to study microbially induced calcite precipitation at the field scale

Microbially induced calcite precipitation (MICP) is a new and sustainable technology which utilizes biochemical processes to create barriers by calcium carbonate cementation; therefore, this has potential be used for sealing leakage zones in geological formations. The complexity of current MICP models present computer power limit the size numerical simulations. We describe mathematical model suitable field-scale studies. main mechanisms conceptual are as follow: suspended microbes attach themselves pore walls form biofilm, growth solution added stimulate biofilm development, uses cementation production calcite, reduces space turn decreases rock permeability. apply study two sets reservoir properties including well-established benchmark system CO$_2$ leakage. A two-phase flow water assess prior with treatment. Based on results, confirms seal paths reservoir-caprock systems.
