This paper reports on a study of microbiologically influenced corrosion (MIC) and its mitigation in gas industry facilities. The results show that MIC commonly occurs on both external and internal surfaces of pipes, in down hole tubulars and in process equipment such as separators. Mitigation strategies were tested in side-stream devices at several sites. The results demonstrate that many biocides and corrosion inhibitors are relatively ineffective in controlling the surface microbial populations, at least under the conditions of the tests. Detailed studies with glutaraldehyde demonstrated that reestablishment of surface MIC communities after removal of this biocide was very rapid. Continuous treatment with glutaraldehyde led to the development of surface microbial communities resistant to the effects of the biocide.
