In order to reduce the computational burden of Full waveform inversion (FWI), we have developed FWI algorithm using plane-wave encoding. Generally, the number of plane-wave gathers is much fewer than that of common shot gathers. Therefore, we can minimize the computational cost to handle massive 3D data sets. In addition, by adopting normalized wavefield excluding source effect, the source wavelet estimation does not need in our inversion process. We validated our algorithm through numerical tests.
