Abstract

Summary

Full Waveform Inversion is an appealing technique to derive Earth subsurface models. With the development of modern HPC architectures, FWI implementations should benefit from the available computing power. In this study, after a review of time and frequency-domain FWI formulations based on time-domain solver for the forward problem, we discuss the theoretical computational complexities of major steps required to build the FWI gradients. It appears that some significant steps are common to both inversion domain, while other steps remain specific. Some experimental values coming from a real 3D FWI application confirm this theoretical analysis, and show that efficient FWI implementation should focus on all these significant steps for an overall speed up.
