For many years, the Institute of geophysics has been developing original versions of the finite-difference migration and wavefield modeling techniques for a valid reproduction of the geological cross-section. The modeling provides a practical test of the accuracy of the reproduction of various geological structure features on a migration result and a way to define, in the observed field, the waves which can be used to produce a migration image of the geologic environment efficiently.
In 2013, the Institute conducted a marine seismic investigation with reflection CDP (Common Deep Point) profiles on the continental slope of the NW part of the Black Sea. The registered wavefields were processed using full-wave finite-difference post-stack migration. The efficiency and validity of the processing methods for various geological structures were evaluated with the help of finite-difference modeling of the wavefield based on solving the wave equation on a grid with a seven-point pattern.
The study validates the precision of marine seismic data processing using full-wave finite-difference post-stack migration with the help of wavefield modeling.
