the effect of microbial activity on the oil viscosity during MEOR process. The results showed for the both bacteria maximum permeability reduction observed at those temperatures and salinities which maximum microbial oil recovery efficiencies were measured showing that for the both bacteria microbial permeability reduction plays an
important role to releasing the oil from porous media. Moreover oil viscosity reduction is found to be another main mechanism for B. licheniformis.
