Microbial-influenced corrosion (MIC) has been implicated in few corrosion-related challenges in the well-service industry in the past. Recently, however, the industry is observing an increase of MIC-related equipment damage. This upsurge of MIC coincides with a switch to unconventional water sources, including recycled water. This paper is an overview of premature coiled-tubing and other-well-servicing-equipment failures and pumping-equipment damage related to MIC.
