DOI: 10.1190/geo2017-0250.1
Abstract: The acoustic-elastic coupled equation (AECE) has a number of advantages when compared to the conventional scalar-wave-based elastic reverse-time migration (ERTM) methods used to image ocean bottom multicomponent seismic data. In particular, vector-wave-based ERTM requires vectorial… read more here.
