Bacteria proliferate both in an aerated medium (aerobic) and in the absence of oxygen (anaerobic).They are responsible for wide-ranging damage in the oil industry.

Bacteria may be responsible for corrosion through:

• The substances they consume (formation of cells of differential aeration in the case of oxygen consumption, or cathodic depolarisation in the case of hydrogen consumption).
• The substances they expel (acids or complexing compounds, hydrogen sulphide).
• Their simple presence (formation of deposits creating heterogeneities).
• Porous material plugging (reservoir, filters) disrupting productivity.
