.... The soil environments in these studies are described as “swampy organic muck” and classified as “uniquely severe” by AWWA ⁽¹⁾ Standard C105. They have a resistivity between 80 and 240 ohm-cm, a very high potential for MIC (microbiologically influenced corrosion), and a fluctuating tidal salt...

... microbiologically influenced corrosion (MIC). The ubiquitous nature of the failures to the exclusion of other possible failure mechanisms and, in most cases, rapid corrosion rates highlight a need for continued industry awareness of the threat of MIC in crude oil facility piping. Four independent metallurgical...

...MIC (Microbiologically Influenced Corrosion) is a well-known source of corrosion which could lead to failure in oil and gas facilities. Common mitigation to control the corrosion due to bacteria shares many success stories, however, a 51 km of 14” condensate line was found severely suffering from...

... of the piping network after hydrotesting promoted Microbiologically Influenced Corrosion (MIC). Hydrotest Weld MIC Stainless Steel INTRODUCTION Prior to commissioning and starting of operation, pipelines and associated process equipment shall be tested for integrity at a pressure above its designed working...

... Abstract Microbiologically Influenced Corrosion (MIC) activities are mostly monitored by using canonical culture-based methods. However, these methods detect only culturable bacteria or require months of incubation to get results. To overcome this, molecular detection methods were developed for many...

...In this case, H⁺ at neutral pH becomes a feasible electron acceptor (oxidant) in Cu corrosion because the corrosion product Cu₂S has an extremely low solubility ¹⁹ . Abstract Microbial biofilms are behind microbiologically influenced corrosion (MIC). Currently, all...

.... Taken together, this study highlights a new strategy to control reservoir souring and potential corrosion issues in producing wells. Reservoir souring MIC SRB biocide sulphide INTRODUCTION Secondary recovery of hydrocarbons often requires the injection of water through injection wells...

MIC aluminum alloy floating roof galvanic corrosion materials performance tanks INTRODUCTION Above-ground storage tanks containing aluminum internal floating roofs are often utilized for storage...

... to increase the integrity threats to JO equipment and therefore, negatively impact the restart of operation. The main anticipated damage mechanisms such as microbiologically influenced corrosion (MIC) and under deposit corrosion (UDC) are likely to manifest in the form of pinhole leaks, leading to increased...

... that Microbiologically Influenced Corrosion (MIC) was the reason for the severe corrosion & leaks. It was observed that Hydrotest waster was not treated and not drained from the system. In this paper, a case study of the failure that occurred in the Desalinated Fire (DF) water line is presented. A brief description...

... of dissolved oxygen, effect of stored crudes quality, frequency of oil movement inside the pipes, steel grade, possible contribution of MIC, presence of deposits, and many others. One of the key roots of corrosion acceleration is the water phase separation. Several approaches were suggested to limit corrosion...

...Abstract For a long time, there was a 10¹ gap in corrosion rates between MIC (microbiologically influenced corrosion) lab tests and fast field cases. However, this gap is effectively closed when using Desulfovibrio ferrophilus (IS5 strain), as sulfate-reducing bacterium (SRB...

Private corporations dominate as the most productive and influential sector in patents for MIC in the oil and gas pipelines. Private...

... corrosion was observed on some of the flanges. There was also some uniform corrosion on the internal surface. Based on the morphological features, the localized corrosion damage appeared to be microbiologically induced corrosion (MIC) and/or under-deposit corrosion. The severe corrosion damage on the flange...

...Based on those results, suggestions are given about the management of MIC in cast iron drinking water systems. EWD (HLC) - High flow rate, low organic matter, complex treatment; EWO (LLC) - Low flow rate, low organic matter, complex treatment; HFH (HHS) - High flow rate, high organic matter...

... found that of the 137 microbial genera identified, 45.3% were associated with biofouling, 29.9% with microbiologically influenced corrosion, 29.1% with a H2S/MIC risk and a 2.9% population did not have a clear link to any of these risks. There was at least 98% relative abundance of bacteria population...

... analysis of the coupon test stations (CTSs) exposed to alternating current (AC) interference from the adjacent power lines was discussed in detail. Corrosion of coupons from the CTSs are mainly due to AC interference, corrosive soil, or microbiological induced corrosion (MIC). This paper provides...
