Transportation of energy carriers (not only oil & gas, but also hydrogen, ammonia, methanol, heating fluids) and carbon dioxide requires the use of extensive pipeline networks that are usually built in metallic materials which are subject to material degradation. Carbon steel being the most prevalent due to its properties, availability, cost, and references. Carbon steel as well as other metallic materials suffer from corrosion processes.

Emergency landings, also known as "aircraft on ground" (AOG) situations, can arise from various causes, including the clogging of jet fuel filters. This paper focuses on the problem of clogged fuel filters and its connection to microbial growth. When a jet fuel filter becomes clogged, even with a full fuel tank, pilots receive a low fuel message, necessitating an emergency landing at the nearest airport. Failure to address the root cause of filter clogging may result in recurring incidents, causing further disruptions to air travel schedules. To mitigate such issues, it is crucial to identify and take appropriate measures to prevent the recurrence of clogged fuel filters. Our analysis of numerous jet fuel filters has revealed that microbial growth is a prevalent cause of clogging. Microbial contamination within fuel tanks lead to filter obstructions, operational disruptions, and emergency landings. In this paper, we will discuss interesting case studies of fuel filter clogging due to microbes, metal chips, and lint. Also, in this paper we will focus on periodic sampling and testing of jet fuels to detect microbial growth. Employing proper tank cleaning procedures, ensuring appropriate fuel handling, and utilizing biocides can effectively control microbial growth within jet fuel systems.

Research shows that microorganisms play a significant role in corrosion of buried steel pipes. Partially hydrolyzed polyacrylamide (HPAM), a polymer commonly used to enhance oil recovery (EOR) from reservoirs, has been found to benefit microorganisms as a nutrient source, resulting in severe microbial corrosion of steel in the vicinity. Herein, microbial corrosion behavior of carbon steel was examined under active Fe oxide and inert sand deposits in oilfield water containing HPAM and sulfate-reducing bacteria (SRB). The electrochemical results show that corrosion rate of the steel under the Fe oxide deposit was generally higher than that under the sand deposit. The steel under the Fe oxide deposit suffered severe pitting assault with wider and deeper pits of about 32.65 µm. In comparison, corrosion severity decreased in the sand-deposited sample (having a maximum pit depth of 11.22 µm). The results demonstrate a synergistic effect between SRB activities and Fe oxide deposits to exacerbate steel corrosion in the oilfield water containing HPAM gel.
