The structural features of the section of the East Siberian region that affect the efficiency and reliability of effective seismic exploration materials are considered. Various parameters of the observation system and their influence on the wave field of seismic sections are analised. As the long time experience shows, the lack of geological information about targets under investigation or its underestimation dramatically reduce the efficiency of processing. Recently, the term “interpretation processing” is increasingly emerging, especially when it is necessary to build a velocity model at the processing stage, which is a complex process. In the complex seismic-geological conditions for the construction of reliable geological models the monomethod use of seismic prospecting is not always effective, and it is required to involve complex studies, which is shown in the article on a number of examples.

Keywords: East Siberia, seismic section, wave field, complexation, processing, seismic exploration, observation system.
