For many decades, the main sources of pollution in the Atyrau region have been hydrocarbon deposits. Currently, the oil and gas industry is widespread and has a significant impact on the environment. The development and development of mineral deposits has a negative impact on all components of the natural environment, including soil. In this study, oil fields located in the Makat and Zhylyoi districts of the Atyrau region were selected as the object of study to assess the ecological condition of the soil. The results of the study make it possible to reliably determine the rate and degree of soil contamination. When conducting observations, generally accepted techniques and methods were used. The soils of the study area are represented by sandy, sandy loam and light loamy varieties. In general, excess of the maximum permissible concentration for heavy metals is observed only in lead and zinc in the Tengiz deposits, which can be explained by the presence of an acidic reduction barrier in the taiga peatygley soil. The content of cadmium, lead, and zinc in the soils of the deposit in some places was found to be below the established maximum permissible standards.
