Elastic reverse time migration with more than pressure data Available to Purchase

In practice, in seismic data imaging, our tools/migrations are utilizing the acoustic approximation whether we use towed-streamer or ocean-bottom node (OBN) acquisitions, as pressure data are used in the migrations most of the time. While elastic full-waveform inversion (EFWI) is becoming more attractive in recent years, the imaging remains acoustic using the pressure data. If we can fully utilize the horizontal and vertical displacement measurements, the elastic imaging may give us additional insights and a new view of the subsurface geology. In this paper, we demonstrate the application of elastic RTM on a sparse OBN data from Gulf of Mexico (GoM) and show comparisons to the acoustic solution.
