In recent decades, special attention has been paid to oil and gas exploration, and now there is a rapid acceleration in the pace of its development and the emergence of new modern methods for solving geological problems. Geophysical exploration, especially seismic exploration, being the only means of searching for oil and gas bearing structures, plays an important role in ensuring oil and gas reserves. Seismic studies have provided unique information for studying the geological structure and compiling a geodynamic model on the surface of the studied objects. On the basis of these studies, the Kashagan field and the Kalamkas-Sea field were discovered. Various regions of the Kazakhstan sector of the Caspian Sea are covered by a regular network of profiles ranging in size from 16x16 km to 4x4 km. Thus, in addition to historical knowledge, these works to date have led to the creation of a voluminous information database of seismic data. But at the same time, due to difficult sea conditions and, accordingly, the high cost of drilling, well information is quite scarce. The scarcity of borehole information leads to great restrictions on the use of seismic information. Within the framework of this work, the elastic seismic properties of an accessible well were studied and the material composition of the geological section and the type of fluids saturating rocks based on seismic data were predicted, which contribute to the study of lithology in deposits and deposits with difficult access to borehole information.
