A novel permeability reduction process has been developed to control fluid flow in porous media. The procedure generally, involves use of bacteria to actively precipitate calcium carbonate as a mineral plugging and cementing agent. This process may be suitably employed to enhance the recovery of oil from oil reservoirs, cement unconsolidated sand underground, or to control the flow of contaminants in an aquifer.
