The main objective for Dr. Ali Morshed's new book, A Practical Guide to Microbiologically Influenced Corrosion (MIC) in the Upstream Oil & Gas Sector, was to produce a practical MIC guide to facilitate the identification, monitoring, assessment, and control of bacterial activity and MIC that might arise within assets associated with the upstream oil and gas sector. "Practical" refers to content that can be readily related to various bacterial and MIC scenarios, which are likely to arise for any upstream operator and (a content which) can be easily used to resolve, rectify, or improve such MIC scenarios. In brief, this book has been written to further help and facilitate bacterial and MIC troubleshooting for the operators and asset owners concerned. Only content and material that have already been satisfactorily tried and tested in the field by various operators have been included. In other words, no theoretical suggestions or instructions, which are based on pure lab work or research-but were never tested in the field-are included. Five relevant and informative case studies are also included.
