Abstract

DUQUE, Zoilabet. A review of corrosion by biogenic sulphide in the oil industry. Rev. Téc. Ing. Univ. Zulia [online]. 2007, vol.30, n.Especial, pp.146-156. ISSN 0254-0770.

There exist serious problems in the water-injection systems of the oil industry due to Microbiologically Induced Corrosion, associated with the presence of Biogenic H₂S. Several investigators consider that the presence of Sulphate-Reducing Bacteria is the principal cause of bacterial corrosion in natural-water storage and distribution systems. But there are other groups of bacteria H₂S producers that are not considered in current microbiological treatments and controls, all caused by the insufficiency of studies that determine the groups of organisms responsible of its production. This review describes the presence of other anaerobic microorganisms that produce this aggressive metabolite or its derivatives in water-injection systems in the oil industry.
