Abstract

Summary

The paper presents 3D diffraction imaging procedure and its application for the fracture zones characterization. The algorithms consist of two methods. The main is the asymmetric summation which provides selective images and is implemented by the double focusing of Gaussian beams. And the additional spectral filtering of selective images is done to remove the residual part of the regular reflections from selective images The methodology is demonstrated on 3D seismic data generated for realistic fractured models.
