Microbiologically influenced corrosion (MIC) is estimated to account for 20% of total corrosion damages. Because sulfate exists in many environments, biofilms formed by Sulfate anaerobicreducing bacteria (SRB) are responsible for MIC. In oilfield water flood systems, SRB cause the largest number of recorded instances of corrosion problems. Current risk-factor probability modelsare useful for predicting the MIC likelihood. However, a reliable prediction of the progression of MIC pitting and the subsequent changes between sessile (biofilms) and planktonic (motile)bacterial populations under different nutritional conditions observed in the oil field has not been reported
