Abstract

Imaging of diffractions is a challenge in seismic processing. Standard seismic processing is tuned to enhance reflections. Separation of diffracted from reflected events is frequently used to achieve an optimized image of diffractions. We present a method to separate diffracted events in the time domain based on the Common-Reflection-Surface approach. The Common-Reflection-Surface method provides a simulated zero offset section as well as kinematic wavefield attributes. Using synthetic data we show, how these attributes can be used to effectively separate reflected and diffracted energy in the 3D case. The objectives of this work are seismic event separation in 3D case and time migration velocity analysis for diffractions implemented in the poststack domain.
