Abstract

Summary

The paper presents 3D diffraction imaging based on spectral decomposition of the different combination of selective or partial images. These images are got by the pre-stack asymmetric migration procedure which is weighted data summation. Spectral decomposition is done in Fourier domain with respect to spatial dip and azimuth angles. Numerical examples with application of different workflows for the synthetic and real data examples demonstrate detailed reliable reconstruction of the fractured zones and reliable reconstruction of fracture orientation on synthetic and real 3D data examples.
