Study the formation of the deposit resulting from the sulfate-reducing bacteria on the steel surface of oil pipe N80

Abstract

This article examines the components of formed deposits on the surface of the petroleum pipes by Sulfate-Reducing Bacteria in the region of Hassi Messaoud (south of Algeria). These bacteria were found in the wells of water and oil. However, we find the problem of bacterial corrosion in the circuits of production and injection when petroleum is extracted. This bacterial corrosion occurs when petroleum which contains water touched the pipes for well long enough to be able to start corrosion. This problem results to the formation of deposits on the inner surface of pipes which lead to the risk of clogging. In this work, we study the deposit resulting from bacterial corrosion on the surface of N80 steel samples and we have identified the most important components of the deposits resulting from the phenomenon of bacterial corrosion
