Increasing P-wave and S-wave velocity resolution with FWI – a North Sea shallow water case study
Increasing P-wave and S-wave velocity resolution with FWI – a North Sea shallow water case study
In this paper, we show, first, how a high-resolution 65 Hz Vp model, obtained using Time-Lag FWI, can improve the imaging from the shallow to the deep. Similar improvements are then shown for PS data using a 30 Hz Vs model obtained from PS ...
