Deep resolution: will ocean bottom node be the answer?

In recent years, Full Waveform Inversion combined with low-frequency, long-offset data have dramatically improved the quality of the seismic velocity models in challenging areas – the biggest impediment to high-resolution imaging at reservoir depth as people thought. However, we have yet to see high-resolution images of deep targets. This begs the question whether the same low-frequency long-offset data are adequate for high-resolution imaging at depth. In the abstract, I use Full Waveform Inversion models with both Ocean Bottom Node and Wide-azimuth Towed streamer field data from the Gulf of America to investigate this open-ended question and speculate potential solutions.
