Abstract:In marine seismic exploration, towed-streamer seismic data acquisition stands out as a prevalent and economical approach. This data records scalar pressure and captures P waves including those that are converted from sub-seabed S waves. Theoretically, towed-streamer seismic data can be used to reconstruct S-wave fields for elastic wave imaging via backward extrapolation. Our research applies an acoustic-elastic coupled equation that includes a pressure term to perform elastic reverse time migration, using the … Show more
