Discovery and Assay Development of the micH Gene, a Novel MIC Biomarker
Despite the long-standing association between methanogens and microbiologically influenced corrosion (MIC) of oil and gas pipelines, neither the type nor abundance of the detected methanogens was correlated with the perceived severity of corrosion. Recent combined efforts have resulted in the discovery and assay development for the micH gene, a globally-relevant MIC biomarker. Early studies of the gene have already provided key thresholds with an observed high probability of severe corrosion (>0.25 mm/yr) when micH abundance is above 1.0 x 104 cells/cm2.

Join This New Joint Industry Project with ExxonMobil Upstream Research Company, DNV, and Microbial Insights, Inc.
This Joint Industry Project (JIP) aims to develop methods, tools and workflows (‘biomarker technology’) to reliably detect the occurrence of MIC in oil field operations. This project will assemble MIC experts from across the industry (JIP participants) and unravel the most relevant microbial degradation mechanisms in carbon steel infrastructure, such as full well stream pipelines, crude transmission lines, produced water piping and sea water injection systems.
