Geographically, the territory under consideration is located in the central part of the Mangyshlak Peninsula, and tectonically within the Zhazgurlinsky depression and the Large Mangyshlak flexure, complicating the central side of the South Mangyshlak trough. In the 50–70 years of the last century, seismic surveys were carried out on the territory of Southern Mangyshlak using the methods of the RWM (reflected wave method) and KMPV (correlations.the method of refracted waves). In this article, the deposits of the upper, Middle and to a lesser extent Jurassic deposits of the Zhazgurlinsky depression are promising. The territory in question belongs to the semi-desert zone and is a slightly undulating flat terrain inclined to the west, that is, towards the Caspian Sea. The western part of the Zhazgurlinsky depression is characterized by a fairly high degree of geological and geophysical study. As a result of seismic studies of the CDPM (Common depth point method) S.P. 1/76–77 of the MOGF (Mangyshlakoilgeophysics) trust, the presence of the Bakand uplift was established,which, according to the V2 reflecting horizon in the Triassic, is a half-circle adjacent to the fault of the sublatitudinal strike. Thus, it should be noted that the western part of the Bolshaya Mangyshlak flexure was studied by seismic exploration to a greater extent than its eastern part, and the use of the latest seismic exploration methods at that time, such as RWM, played a significant role in identifying local structures at great depth.
