Glutaraldehyde and quaternary ammonium chloride salts are widely used biocides in oil field systems to control microbiologically influenced corrosion (MIC). These biocides and others were evaluated for their efficacy to control sessile and planktonic sulfate reducing bacteria (SRB) and aerobic bacteria. The efficacy of these biocides was then compared. In addition to laboratory evaluation, all the biocides were evaluated against SRB and acid producing bacteria in two different field waters. It was found that the blend containing aldehyde and quaternary amine was, in general, a more effective biocide than either glutaraldehyde or quaternary amine alone.
