“…Biogenic H 2 S from the reservoir is carried in produced fluids and gases to production facilities where it can exacerbate corrosion. More importantly, H 2 S can lead to catastrophic failures of carbon steel well tubing and other high-pressure equipment through sulfide stress cracking (10).…”

Ambiguous reports of corrosion problems associated with the injection of nitrate for souring control necessitate a deeper understanding of this frequently applied bioengineering strategy. Sulfide-oxidizing, nitrate-reducing bacteria have been proposed as key culprits, despite the underlying microbial corrosion mechanisms remaining insufficiently understood. This study provides a comprehensive characterization of how individual metabolic intermediates of the microbial nitrogen and sulfur cycles can impact the integrity of carbon steel infrastructure. The results help explain the dramatic increases seen at times in corrosion rates observed during nitrate injection in field and laboratory trials and point to strategies for reducing adverse integrity-related side effects of nitrate-based souring mitigation.

In offshore production facilities, large amounts of deaerated seawater are continuously injected to maintain pressure in oil reservoirs and equivalent volumes of fluids, composed of an oil/gas, and water mixture are produced. This process, brewing billions of liters of biphasic fluids particularly rich in microorganisms, goes through complex steel pipeline networks that are particularly prone to biofilm formation. Consequently, offshore facilities are frequently victims of severe microbiologically influenced corrosion. Understanding of microbiologically influenced corrosion is constantly growing. In the laboratory, the inventory of potentially corrosive microorganisms is increasing and microbial biochemical and bioelectrical processes are now recognized to be involved in corrosion. However, understanding of corrosive multispecies biofilms and the complex metabolic processes associated with corrosion remains a considerable challenge as simple laboratory biofilms comprising pure or defined mixed cultures poorly represent the complexity of in situ biofilms. Complementary, antagonistic, and parallel microbial pathways occur within the complex microbial and inorganic matrix of the biofilms which can lead to high corrosion rates. This mini-review explores models of microbiologically influenced corrosion and places them in the context of the multispecies biofilms observed in situ. Consequences of mitigation strategies on biofilm corrosiveness and dispersal are also discussed.
