Peculiarities of the modern seismic prospecting technology applying reflection method (OGT-3D) are considered. The conducted seismic works should result in detailed data about elastic behavior of the geological section under study. The data are received with the use of kinematic and dynamic properties of the records. Elastic behavior is connected with the composition and conditions of sedimentation and rock formation that are essential for geological interpretation of seismic data such as prediction of the geological structure of the area under study and probable mineral deposits (oil, gas, coal etc.). The seismic prospecting is optimally used for prospecting and exploration of oil and gas deposits. Technology parameters correlate with the geological structure complexity in the areas of sedimentation. The modern seismic prospecting makes it possible to predict the location of oil and gas deposits with high probability (on shore and in offshore areas), that is why seismic prospecting is included into essential works for all probable wells. This approach allows to reduce the number of non-productive wells and cut costs of exploration of oil and gas deposits. The method has proved high geologic and economic efficiency in the field of oil and gas exploration. Thus the method turns into an industrial branch capable of solving fuel and energy tasks. Oil seismic prospecting costs account for 90-95% of total field geophysics expenses. The paper gives examples of MOV-OGT seismic prospecting implementation in the prospective areas of Timano-Pechorskaya province
