Abstract

The final procedure of the standard production processing and interpretation of seismic data is the post-stack migration by the central deep point method (CDP). However, in practice, a more informative image of the deep section is given by the pre-stack migration according to initial seismograms. The actual task of processing and interpretation of the observed wave field to produce the image of the deep structure without the procedure of the CDP stack is presented. This solution is implemented using a new version of the finite-difference pre-stack migration of the shot record in time domain. The advantages and possibilities of applications of this method are shown in model and real examples.
