摘要
Field seismograms are gathered into sets having reflections from asymmetrical common reflection points where there is a conversion between longitudinal waves and shear waves. The gathered seismograms are stacked to produce a seismic section which emphasizes the reflections from particular types of formations. In particular, reflections from formations having a significant difference in longitudinal to shear wave velocity, such as oil and gas saturated formations, are emphasized in the stacked section.
