摘要

There is a corrosion phenomenon, Microbiologically Influenced Corrosion (MIC), that has beenmisunderstood and misdiagnosed in the electrical submersible artificial lift industry for years. MIC canbe caused by sulfate reducing bacteria (SRB), as well as, other anaerobic and aerobic bacteria.This phenomenon has been known by some in the industry, but it has been my experience as a CorrosionChemist/Forensic Engineer that this corrosion phenomenon is not well understood in the 'Oil Patch'.Therefore, this phenomenon may be overlooked as a corrosion mechanism.A better understanding of this issue could reduce the corrosion damage and the cost associated with amisdiagnosis. In an effort to further the understanding of'microbiologically influenced corrosion', as itis manifested in the artificial lift industry, this paper is a presentation of MIC experienced by a numberof oil companies around the world. This corrosion phenomenon may be misdiagnosed in the entire fieldof corrosion study, but this paper will focus on MIC issues in the artificial lift industry.
