ABSTRACT

We propose an iterative method for a large-scale frequency domain solution of the elastic wave equation in 3D heterogeneous media for full waveform inversion (FWI) of land seismic data. The method is based on a Krylov-type technique with a semi-analytical preconditioner. The method is adapted for use on HPC clusters with distributed memory. It converges fast for low frequencies required for inversion and demonstrates good accuracy.
