Abstract

The Full Wavefield Migration (FWM) algorithm has some additional features comparing to conventional least-squares imaging. It requires to store wavefields from previous iterations to take into account multiple scattering. We revise this approach and propose to recompute the wavefields instead of keeping them in the memory. It allows us to reduce the memory requirements and makes the algorithm more fault-tolerant and suitable for distributed computing. We apply the modified algorithm use the modified code on one of the public cloud providers.
