... corrosion forensic investigations sometimes end up with unclear or vague conclusions as to the causative mechanism because there is insufficient data to decisively discern between microbiologically influenced corrosion (MIC) and abiotic corrosion mechanisms, e.g. CO₂, hydrogen sulfide...

... Corrosion costs between 1–5% of global gross domestic product annually. Microbiologically influenced corrosion is believed to contribute to around 20% of this. Due to the complexity of the microbial populations involved, the mechanisms of many of these processes are still poorly understood. Culture-based...

... the role(s) these microbes have in the MIC process and how the interactions between the microbes from different classes affect MIC. Corrosion stemming from the activity of bacteria and archaea can lead to severe consequences to the petroleum industry. Microbiologically influenced corrosion (MIC), can...

...Abstract Oilfield microorganisms are directly responsible for many problems in the oil and gas industry, including microbiologically influenced corrosion, biofouling, reservoir souring, as well as employee injury. Recent efforts in both industrial and academic microbiology labs have been focused...

... this assumption. It is unlikely that planktonic samples alone can adequately monitor a system. To what extent these samples are actually representative of the sessile population is largely unknown. INTRODUCTION It is often a challenge to obtain representative microbiological samples in the oil and gas industry...

Although peracetic acid is a potent biocide, it is unique in that it does not produce toxic byproducts and its decomposition products, acetic acid, water and oxygen, are innocuous and environmentally acceptable. peracetic acid biocide cooling water process water biofilm microbiology...

Remedial actions were developed based on field data and this mechanism of reservoir souring. Souring hydrogen sulfide microbiology biofilms corrosion MIC field testing water injection...

...Is the end in sight? Not at all. There is still much to learn about the chemical, microbiological, metallurgical and engineering aspects of MIC. The Corrosion/93 symposium includes papers touching on all of these important areas. The diversity and range of subjects covered shows that MIC has become...
