Abstract (summary) One of the problems of interpretation of seismic data is that they are often measured on an irregular grid with large distances between the sources and receivers, which affects the outcome of processing. The article discusses the possibility of using the procedure RTD (Reverse Time Datuming) [1-4] to ob-tain the wave field with a dense and regular geometry of sources and receivers at some depth. The results of numerical testing are presented.
