Combining Full Waveform Inversion and Tomography: Full Waveform Inversion-guided Tomography

With the new broadband acquisitions, allowing to record frequencies down to 2,5 Hz, and the new tomographic tools, allowing to resolve for vertical velocity components up to 6 Hz, we have moved for velocity model building from the situation of a mid-frequency gap to the situation of an overlapping area in terms of resolution we can expect from tomography and migration-inversion. Full waveform inversion-guided migration velocity analysis has been proposed as an approach taking advantage of this new situation. We show here a first real data application of this innovative approach.
