Full-Waveform Modeling for Solving the Direct and Inverse Seismic Problems in the Tomsk Region

Summary Up till recently, the Pre-Jurassic formations were not considered as a separate exploration target because of their complicated structure which required adaptation of conventional exploration methods to be looked at. Because of its complex structure and the existence of the more readily available reserves of the Jurassic and Cretaceous reservoirs, the Paleozoic formations have not been studied well enough, and some fundamental research will help reveal new regularities. As a part of Paleozoic project, the full-wave modeling was used in order to reduce risks during field seismic surveys for the pre-Jurassic complex in the Tomsk Region. Results of testing seismic data processing and interpretation procedures on model data was used to formulate requirements for the methodology of seismic field acquisition in the area of study and an optimal graph for processing 2D and 3D seismic data .
