Corrosion Induced by APB Acid-Producing Bacteria Isolated from an Oil Field in Southern Algeria

Faiza Khoukhi*

This study examines industrial corrosion caused by acid-producing bacteria isolated from the filters of a water separation facility at an oil field in southern Algeria.

This water is used for injection to maintain reservoir pressure.

An on-site monitoring system was implemented using a bioprobe and corrosion coupons, with findings subsequently validated through laboratory testing and analysis.

The study investigates the behavior of carbon steel in the presence of acid-producing bacteria (APB) over a 45-day immersion period; scanning electron microscopy revealed biofilm formation and localized corrosion zones on steel coupons immersed in APB-contaminated injection water treated with a biocide.
