Control of MIC. Microorganisms in the injection water and produced water may have the opportunity to attach to metal surfaces in regions of low flow rates. If allowed to form biofilms, the microorganisms could contribute to microbiologically influenced corrosion (MIC) of the injection system. MIC events in the injection system can lead to corrosion failures of pipelines and pumps, with the related problems of equipment downtime, lost production and environmental hazards caused by spills or releases. It is safe to say that the overwhelming purpose of using biocides in the oilfield is to control MIC. 

Microbial corrosion (also called microbiologically influenced corrosion or MIC) is corrosion that is caused by the presence and activities of microbes. This corrosion can take many forms and can be controlled by biocides or by conventional corrosion control methods.
