Abstract

Most full waveform inversion (FWI) algorithms are based on the acoustic wave equation. However, only a few studies are related to the elastic FWI, even though many geological targets of seismic exploration are located on elastic media. Therefore, to invert the subsurface properties accurately, we must develop a suitable FWI algorithm for generating elastic parameters. In this paper, we developed an elastic hybrid FWI algorithm, in which wave-modeling is performed in the time domain, and other procedures are conducted in the Laplace- Fourier domain. As a modeling operator, we employed the staggered-grid finite-difference method using a first-order elastic wave equation. To validate the feasibility of our proposed algorithm, we applied it to land data recorded from Alberta, Canada.
