Abstract

We propose a method for imaging small scale diffraction objects. It is based on separation between specular reflection and diffraction components of the total wavefield in the migrated domain. Reverse-time migration was utilized to produce surface dip-angle common image gathers. We used continuity of diffractions in the dip-angle CIGs as a criterion for separating reflections from diffractions. Synthetic and real data examples illustrate efficient application of the method in case of moderate lateral velocity variation.
