Comparison of the characteristics of casing gas components and stable carbon isotope of microbial activated water injection oil wells and formation water injection oil wells from Bai-153 block from Changqing oil field in China. The results indicate that the composition and stable isotopes of the gaseous hydrocarbons from activated water changed obviously due to the effect of microbial. The characteristics of components and stable carbon isotope of casing gases which can be easily collected can be used to monitor microbial activities in reservoir, adjust the amount, concentration of microbial of injection, and to quickly evaluate the efficiency of MEOR. This evaluation method is proposed for the first time as we know.
