Abstract


Seismic imaging, particularly below coal and subbasalt layers, is a major challenge in the Cambay basin. Accurately delineating deeper horizons on time-migrated sections is still a challenging task for interpretation, especially when prominent lateral variations in physical properties are present. The energy scattering near point diffractors and faults results in an increase in ambiguity. The high velocity
