ABSTRACT
Corrosion is the deterioration of a material due to its interaction with the environment. It is a natural phenomenon, which should not surprise one, but rather should be expected to occur. Metals are high-energy materials which exist because heat energy was added to natural iron ores during the smelting process. The location of anodes and cathodes tends to move randomly over the surface of the metal for alloys that are subject to general corrosion. High safety concerns and strict standards applicable to the oil and gas industry mean that constant monitoring is needed to identify the presence and extent of corrosion. The effect of corrosion on oil and gas pipelines can be catastrophic. Generally, at the anodic locations, there is corrosion damage, while at the cathodic location, no corrosion damage occurs. Microbiological corrosion, also called bacterial corrosion, bio-corrosion, microbiologically influenced corrosion, or microbially induced corrosion, is corrosion caused or promoted by microorganisms.
