Summary:
The perennial seismic work carried out under the conditions of the salt tectonics of the sedimentary cover, as well as the saturation of its trap intrusions, showed the low efficiency of the traditional methods of wavefield correction, based only on seismic characteristics. The involvement of other geophysical methods, such as electrical prospecting, and magnetic prospecting, with the exception of special cases, did not solve this problem. Similar problems are, in particular, for the areas of the south of the Siberian platform, on the work sites of the Irkutskgeofizika enterprise and other organizations. The application of the presented method of correction the static corrections made it possible to minimize the differentiation of the wave field at the ambiguous sections of the preliminary time profiles
