Most of the identified hydrocarbon deposits in Russia are at a late stage of development. For further effective study of sediments in various territories of the oil and gas regions of Russia, it is necessary to improve approaches and techniques for studying their areal structure, primarily the geological objects that make up the section. At the present stage, such studies are carried out using seismic research. In the old oil and gas producing regions of Russia, the undetected part of the resources is often concentrated in small-sized anticlinal and non-anticlinal objects, which are poorly detected in the seismic field. When prospecting for low-amplitude traps, additional difficulties may be caused by the strong variability of the upper part of the section, which introduces uncertainties in the degree of reliability of constructing structural plans based on seismic data. The accuracy of constructing the structural surfaces of the reflecting horizon when interpreting the results of seismic studies is comparable to the amplitude of the uplift. The purpose of this work is to identify and map zones and areas of development of geological objects with anomalous properties in the upper part of the section of the Cenozoic-Paleozoic sedimentary mantle for subsequent consideration of their influence on the results of seismic exploration using the areas located within the platform part of the Republic of Bashkortostan. Based on the research results, geological preconditions were established that determined the formation of geological objects with anomalous properties in the upper part of the section, which can negatively affect the results of seismic exploration. The minimum required set of geological and geophysical information has been determined and an algorithm has been developed that makes it possible to identify and map zones of their development. The research results were used in the process of desk processing of materials from 3D work using common depth point method when calculating static corrections, which made it possible to minimize the influence of velocity inhomogeneities and increase the confirmability of structural plans during seismic exploration. This approach was recommended for use throughout the platform part of the Republic of Bashkortostan.
