“…However, during production operations like water injection and shale gas hydraulic fracturing, a significant number of microorganisms are inevitably introduced. This has led to corrosion of metal pipelines in oil and gas field casings and gathering systems, causing substantial economic losses [2] and garnering considerable attention from researchers [3][4][5][6].…”

Microbiologically influenced corrosion has become a predominant cause of pipeline and equipment failure in oil and gas fields. This research examines the corrosion behavior of steels with varying chromium contents in simulated shale gas formation water environments. Weight loss testing, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), Focused Ion Beam (FIB), Transmission Electron Microscopy (TEM), and X-Ray Photoelectron Spectroscopy (XPS) were employed. The findings suggest that an elevated Cr content in steel results in a gradual reduction in its uniform corrosion rate in a CO2-SRB coexistence environment. This can be primarily attributed to the significant distribution of Cr content throughout the entire product film, including both biofilm and corrosion products, thereby enhancing the product film's protectiveness. Additionally, the competitive corrosion between CO2 and SRB, as well as the influence mechanism of Cr on corrosion, were discussed.

Corrosion of materials, induced either by chemicals, or environmental factors or microbials is always a threat to industries. If remain unattended, it will have direct influence on environmental pollution. In recent years lot of work is reported on microbially influenced corrosion which is more prevalent in biotechnology and chemical engineering process industries. However, reports for preventive measures which are taken to mitigate microbially induced corrosion are highly limited. This review is an attempt to consolidate and make a systematic, up to date report on various control techniques that could be implemented to overcome microbially influenced corrosion. The review report opens up by highlighting the causes and concerns related to microbially influenced corrosion, and explains in detail mechanistic aspects of it. It provides in-depth view on attenuating microbially influenced corrosion by using synthetic compounds, green inhibitors, surface modifications, biofilm formation, and nano-particles. The review critically discusses the corrosion inhibition mechanism with merits and limitations of each microbially influenced corrosion inhibitors.

The loss of materials due to corrosion is inevitable and has gained significant attention at various stages in the process industries, including petroleum, food processing units, and tanneries. With significant detrimental effects occurring as a result of microbial activity, the research on microbial corrosion and methods to keep them under control has become essential. About 10% of the corrosion affliction to metals and non-metals is due to microbial activity. The Microbiologically Influenced Corrosion (MIC) is a consequence of the contact, which are synergetic between bacteria and metals. A typical marine electroactive bacterium shown to produce severe MIC is Pseudomonas aeruginosa. In the maritime environment, Pseudomonas aeruginosa is a bacteria that is extremely corrosive to stainless steel. However, little is known about how P. aeruginosa causes corrosion on stainless steel. Stainless steel is a beneficial material that has been employed in various applications due to its corrosion-resistant properties and mechanical strength. The property of stainless steel to strongly resist corrosion is owed to the presence of chromium in its composition. The chromium forms a passive film of chromium-rich oxide in aerobic conditions at low temperatures, which protects it from the surroundings. This layer can be harmed by harsh weather conditions. The microbial activity and their existence can modify the inorganic passive layers, raising their dissolution levels and detaching them from the surface of the metal. The review aims to study steel corrosion as a result of microbial activity. The explicated methodologies are more significant within the broader context of metal–microbe interactions.
