Permeability profile modification using bacterially formed calcium carbonate: comparison with enzymic option

Porous media permeability profile modification was studied using biomass and bacterially formed CaCO 3 as plugging agents. The candidate bacterium, an isolate from a Canadian oil field, was able to decompose urea at concentrations as high as 20 g/L. Bacterial production of CaCO 3 was achieved in the...
