Adaptation of focusing transformation to 2D multifold seismic data

Focusing transformation of wavefields appears to be a powerful tool for structurally complex<br>environment study. Under severe seismogeological conditions application of focusing<br>transformation considerably increases quality and lateral resolution of seismic sections. The main<br>difficulty of this application lies in the selection of focusing system parameters (optimal number of<br>sources and receivers, distances between offset midpoints, etc.) necessary to image a specific<br>geologic event.<br>A method aimed at fitting parameters of the focusing system applied to real 2D multifold data<br>obtained in Western Siberia is presented in this paper supported with the examples of focusing<br>transformation application to real data.
