Bacteria population density may provide a viable corrosion control metric for microbiologically influenced corrosion (MIC) in wet and dry crude systems such that the population of sulfate reducing bacteria (SRB) general aerobic bacteria (GAB) and general anaerobic bacteria (GAnB) in an operating environment can be kept below a target envelop to preserve asset integrity. Consider a system with various degrees of water separation/accumulation which has been experiencing increased corrosion over a period of time. If the trend of increasing corrosion rate versus time parallels the corresponding degrees of water separation/accumulation as well as bacteria population density over that same period of time the pragmatic assumption is to ascribe the source of increased corrosion not only to water separation/accumulation but also to the increased bacteria population density. This paper investigates the role of water separation/accumulation and bacteria population density on general/pitting corrosion in assessing asset integrity of wet and dry crude systems.Key words: Bacteria Population Density Sulfate Reducing Bacteria (SRB) General Aerobic Bacteria (GAB) General Anaerobic Bacteria (GAnB) Microbiologically Influenced Corrosion (MIC) Asset Integrity Wet Crude Dry Crude.
