The article is devoted to the analysis and systematisation of the data about hydrocarbon deposits of the Republic of Kazakhstan, highlighting those aspects that will allow of using the method of the microbiological impact on oil reservoirs. This technique of influence refers to the chemical methods of the tertiary recovery stage of the development of the oil deposits. It has already proven its effectiveness in highly depleted, waterflooded formations with irregular, diffuse oil saturation. Its main advantages are its relative cheapness, as it does not require additional equipment for injecting microorganisms into the stratum, and for their nutrition, as a rule, food industry waste is used, and its use cannot cause harmful effects on the environment. In addition, with the help of the Internet discrepancies in the information that is in the public domain and that one, which can be found, including the websites of the other countries, were subsequently described in the article. A fairly extensive database was compiled, and after, based on it, various classifications of the republic's deposits were created.
