Dynamic Resolution Time-Lag FWI (DR-TLFWI) aims to use both diving waves and reflections for velocity update with optimized low- and high-wavenumber components from shallow to deep section. The proposed method builds contrast into the velocity model, enabling the simulation of reflections. The iterative velocity ...

Superimposed reservoirs are common in oil and gas production, but they are challenging to monitor with time-lapse seismic imaging. A common seismic attribute used for assessing reservoir evolution during production is the time-shift measurement which is obtained comparing two 3D seismic images. In the ...
