Abstract :Using viable microbial cultures within hydrocarbon reservoirs so as to enhancement of oil recovery through metabolic activities is exactly what we recognize as Microbial enhanced oil recovery insert ignore into journalissuearticles values(MEOR);. In similar with many other process in industries, there are some cons and pros following with MEOR. The creation of sulfides such as hydrogen sulfide as a result of injecting the sulfate-containing seawater into hydrocarbon reservoirs in order to maintain the required reservoir pressure, leads to produce and growth of Sulfate Reducing Bacteria insert ignore into journalissuearticles values(SRB); approximately near the injection wells, turning the reservoir into sour, however SRB is not considered as the only microbial process stimulating the formation of sulfides. Along with SRB, thermochemical sulfate reduction or thermal redox reaction insert ignore into journalissuearticles values(TSR); is also known to be highly effective at resulting in having extremely concentrated zones of
