Technical Abstract

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

Back to Technical Content
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.
