The incidence and proliferation of microbial population in oil and gas production facilities can have undesirable consequences on upstream, midstream and downstream production systems. Microbes thrive in the anaerobic conditions encountered in these systems and are supported by nutrients and metabolites found in produced water. Although the majority of process and water injection systems are susceptible to microbial fouling, the development of microbial activity is exacerbated by specific conditions such as stagnant fluids or the presence of deposits.1 Threats of microbiologically influenced corrosion (MIC) and other challenges associated with microorganisms have become valid as more cases are reported. While MIC, biofouling (BF), and reservoir souring are three of the most common problems associated with microbes, many other production issues can be attributable to microbial activity including: employee infections, filter plugging, loss of injectivity, and metal sulfide deposits.2
NEW TITLE AVAILABLE NOW!! 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.
Five relevant and informative case studies are also included.

This paper presents the findings of an investigation that was carried out to determine the root cause of the premature failure of Ni-coated carbon steel fittings on the water injection composite piping system installed at an oil production facility in Western Canada. The facility had been in operation since 2011 without major corrosion issues. Many of the Ni-coated fittings, which are expected to have a service life of 20 years, started to fail (developed leaks) unexpectedly after about 4 years. The core structure of composite pipe is a high-density polyethylene (HDPE) inner pipe, a middle layer of high-strength dry fiberglass, and a protective thermoplastic outer jacket. The interconnecting fittings are made of carbon steel coated with a thin, ~40 micron (1.5 mil) layer of Nickel.
In the Netherlands, a large drinking water distribution system exists which composes of a complex network of underground pipes owned by several water companies. Part of the drinking water distributions pipes consist of cast iron pipes of which some have been installed more than 80 years ago.1 To prevent leaks, it is desirable to have insight into the condition of these pipes and the risk of leakages or even pipe bursts. During local replacements and maintenance work, corrosion is regularly found in the pipes and previous research7 has indicated that Microbiologically Influenced Corrosion (MIC) may be involved in this corrosion that is found in the pipes.
The lengthy laterals of horizontal wells often pose microbiological challenges, as they provide more area to become microbially contaminated and require larger volumes of fluid and biocide for treatment. A Permian Basin oilfield has been experiencing MIC-related failures in its horizontal wells, which is of concern due to the associated high workover cost.
Laboratory biocide challenge testing identified several common oilfield chemistries and combinations thereof as being effective against this field’s population of microbes. However, aggressive applications of these products in the field neither delivered an effective microbial kill nor prevented the treated wells from experiencing further MIC and failures.
An acrolein field trial was conducted on a set of problematic, microbially contaminated horizontal wells over a time period of approximately one year. During this timeframe, these wells experienced microbial control for the first time, defined as meeting and maintaining microbial KPIs. Additional benefits were realized as a result of acrolein, including a dramatic improvement in water quality evident as a decrease in iron sulfide and suspended solids, a clean-out of the wells inferred by an initial increase of solids post-acrolein, a decrease in the corrosion rate as indicated by a significant reduction in iron and manganese counts, a decrease in the well failure rate, an increase in production, and an overall cost savings associated with the application of acrolein.
