At all stages of geological exploration, field geophysical studies and, in particular, seismic exploration are of great importance, the task of which is to study the geostructural features of large territories, identify tectonic elements of various orders, and detail the geological structure of the studied territory. The purpose of the study is to study the features of various methods of seismic exploration and determine their significance for solving the tasks assigned to them. The methodology of the study was carried out using the methods of field geophysics - seismic exploration and the methodology of processing the obtained materials. In recent decades, significant progress has been observed in the field of oil and gas exploration, which has led to the emergence of new technologies, both for field seismic exploration, and for data collection and computer processing. In 1980-1990, a method of three-dimensional seismic exploration was developed, which allows obtaining three - dimensional pictures of the earth's interior. For the geological interpretation of seismic data, geodynamic methods are used, which are based on the study of the genesis of the studied section. These include methods for seismic and sequestration, structural-formational interpretation. Currently, Russian companies pay great attention to the introduction of methods that belong to the category of high-tech seismic exploration. First of all, it is HD seismic exploration and dense seismic exploration. Seismic exploration methods occupy the first place among geophysical methods in terms of resolution and the variety of geological problems solved with the help of them.

Key words: Seismic exploration, field geophysical methods, interpretation of materials
