The relevance of the work is due to the scientific substantiation of the materials of geological exploration carried out in the North-Eastern part of the Astrakhan arch. The purpose of the study is to analyze the data of seismic exploration and drilling of search wells to justify the prospects of the area for the purpose of search and exploration of mineral deposits. The study methodology was based on the study and processing of data from field Geophysics materials - seismic exploration and drilling of search wells, as well as core and slurry materials. The author studied the geological sections for all the drilled search wells of the Kharabalinsk-Elenovskaya uplift zone and used materials from seismic data processing to identify priority objects that are promising for their further study. For the North-Eastern part of the Astrakhan arch, preliminary factual material on the age, composition and distribution of rock types of Paleozoic subsalt complexes was obtained.
