Microbiologically influenced corrosion (MIC) is a significant challenge in the oilfield that results in significant cost for the operator in downtime pipe and equipment replacement and safety hazards associated with failures. One option for minimizing the risk of MIC is to treat the system with a biocide to kill microbes. However effectively controlling a microbial population present as a biofilm is much more challenging than controlling microbes present in planktonic form. Most of the currently available biocides simply kill the outer layer of the biofilm resulting in sub-optimal MIC risk reduction. Furthermore biofilm removal is just as important as microbial kill in order to ensure that under-deposit corrosion does not occur. To this end a novel biocide has been developed that provides microbial kill within a biofilm as well as biofilm removal. This novel biocide was initially evaluated against a biofilm in a stagnant environment and shown to be very effective. It was then tested in a dynamic flow loop against a best in class commercially available biocide. Lastly the novel biocide was applied in the field and was able to effectively control the sessile population. This data suggests that this novel biocide has the potential to be used to treat various systems where MIC is a concern.
