Direct Problems in Seismic Data Processing and Interpretation

The solution of direct problems in the process of seismic data processing and interpretation is an important element which determines the information capability of the method in the specific seismic environment and with the account of the specific geological objectives. It is used at the stage of the choice of a seismic acquisition design, seismic processing sequence, the type and the content of seismic record attributes, as well as the correctness of the obtained results (structural models, the forecast of lithofacial characteristics of deposits, prospective oil & gas deposits and their reservoir properties). In addition, only the processing and interpretation of wave fields synthetic data may help to determine the real possibilities of Geophysics for the specific region. The usage of different solutions of direct problems, including the calculation of synthetic seismograms, is explained in this paper. The authors show the results obtained under the conditions of salt tectonics with the usage of complex processing sequence, including wave fields transformation procedures (such as datuming & redatuming).
