The paper considers the possibility of using data obtained in the course of dynamic analysis of sites seismic survey materials for predicting zones of complications caused by geological causes during drilling. When developing fields, at the stage of planning new wells, it is necessary to comprehensively assess the trajectory of new wells, since during the drilling process, there often occur complications due to geological causes (adsorption, collapses). In case of long intervals of such complications, it is possible to attract seismic survey materials for the forecast. In the presence of high-quality seismic materials and a sufficient number of wells with a full set of geophysical studies, there are prerequisites for conducting dynamic analysis of seismic materials, which will make it possible to identify anomalies along the trajectory of the planned well. This information will serve as a basis for quickly adjusting the location of new wells, or allow planning the activities aimed at preventing complications before they are opened by drilling.
