Diffraction Imaging from Full-Azimuth Data and Legacy Data for Improved Structural Resolution

In depth migration, recorded wavefield components mapped at each depth point consist of specular energy and diffraction energy. Paradigm innovates with a technique in which the diffracted component is separated from the total migrated wavefield.  That diffracted component plays a vital role in building an accurate structural framework. By designing an optimal filter, diffraction imaging can also be used to map small scale subsurface geological objects and discontinuities such as faults and uncomformities. This methodology enables geoscientists to improve structural resolution, and perform accurate interpretation and modeling for further exploration workflows.
