Microbes vs. Pipelines: Using Molecular Methods to Track Corrosion Culprits

Microbiologically influenced corrosion (MIC) is a key integrity challenge in oil and gas pipelines, especially in high-water systems. While sulphate-reducing bacteria (SRB) are traditionally seen as the main cause, modern molecular tools reveal more complex microbial interactions.

Our case study: 'Microbes vs. Pipelines: Using Molecular Methods to Track Corrosion Culprits' by Dr. Heike Hoffmann, shows how Next Generation Sequencing (NGS), corrosion testing, and chemical analysis were used to assess MIC risk in a crude oil pipeline. Results highlighted a diverse microbial community and multiple interacting species contributing to corrosion beyond SRB alone.The study demonstrates the value of advanced molecular methods for improving MIC detection, risk assessment, and mitigation strategies.
