Abstract
The article is devoted to the analysis and systematization of data on hydrocarbon deposits in the Republic of Kazakhstan, highlighting those aspects that will allow the use of this method. The microbiological method of exposure refers to the chemical methods of the tertiary stage of development of oil reservoirs. It has already proven its effectiveness in highly depleted, waterflooded formations with irregular, diffuse oil saturation. Its main advantages are its relative cheapness, it does not require additional equipment during injecting of the microorganisms into the reservoir, and for their nutrition, as a rule, food industry waste is used, and its implementation cannot cause harmful effects on the environment. Also, a fairly extensive database was compiled, according to which various classifications of the republic’s deposits were created.
