Abstract

The most severe corrosion due to bacterial activity in pipe steel for the transportation of water and the injection systems is influenced by sulphate reducing bacteria (SRB), thiosulphate reducing bacteria (TRB) and others microorganisms. In the aim to reduce the impact of bacterial corrosion, steel pipes were substituted by fiberglass pipes. These types of materials are very resistant to corrosion and the life of use was prolonged. Fiberglass pipes are used for the water transportation that be used for the water flooding systems in the oil fields and fire systems. During the opening of a section of the fiberglass line, the scale found inside this line, produced a smoke that was followed by a fire that provoked the inflammation of the fiberglass. Also, the aim is to understand the phenomena and a suspicion of the role of some bacteria in this phenomenon. The identified bacteria in all the samples show the presence of sulfate-reducing bacteria, methanogenic bacteria and fermentative bacteria. We think that by synergic effect, the growth of these microorganisms transform heavy organic molecule to methane and others chemicals species. The methane is gas and under the effect of the sun may start fire.
