Paper Summary
We present a robust depth imaging workflow that incorporates high-resolution Full Waveform Inversion (FWI) and reflection tomography constrained by geological interpretation. This approach has allowed us to both update the long wavelength and the fine details of the velocity model by a simultaneous combination of eight vintage streamer surveys characterized by a wide range of acquisition parameters. We demonstrate the benefits of this integrated scheme by presenting the results from the West of Shetland area, offshore UK.
