Microbiologically influenced corrosion (MIC) is a key oilfield problem associated with microbial activity, and can be described as the accelerated corrosion of surfaces (usually concrete or iron/steel) by the biological action of naturally present or externally introduced microorganisms. MIC incidents can occur anywhere that a system is exposed to the environment, where microorganisms can enter often via fluid flow and colonize various surfaces for their own growth. MIC is a persistent concern in practically any upstream, midstream, or downstream system where water could be present for microorganism colonization, including topside, subsurface, aerobic (with oxygen), anaerobic (without oxygen), and at extreme temperatures and salinities.
