Abstract:

Kazakhstan is experiencing a gradual decline in commercial oil reserves. First of all, this is due to the low probability of discovering new large deposits in the main oil and gas complexes, which are well studied by geological and geophysical methods.

Purpose. To identify key criteria that determine the possibilities for searching for hydrocarbons in a given geological area.

Methodology. The study includes an assessment of the underground horizons’ structural features, reservoir properties analysis and study on hydrogeological parameters of the region.

For the analysis of hydrocarbon potential, the results obtained while conducting geological exploration work were used. The methods of mathematical statistics were used to process the experimental data.

Findings. The results of a complex analysis of geodynamic and hydrogeological factors affecting the hydrocarbon potential of the Alakol depression in Kazakhstan are presented. Geodynamic criteria play an important role in the assessment and exploration of oil and gas deposits. In this connection, the main geodynamic factors which are usually considered when studying the oil and gas potential are shown.

Originality. Based on the data from geodynamic and hydrogeological studies, it can be concluded that there are three eras of intense sedimentation in the region, with a special emphasis on the Carboniferous and Jurassic. Lower Jurassic deposits are important to study, especially in the context of hydrocarbon potential. Therefore, the results of the assessment of the oil and gas potential of the Alakol sedimentary basin are of scientific novelty.

Practical value. The results of the study are of practical significance and can be used in planning and carrying out work on the search and exploration of hydrocarbons in the Alakol depression.

Keywords: hydrogeological factors, geodynamic criteria, Alakol basin, hydrocarbon potential, oil
