Abstract
Kim, S.Y., Chung, W.K., Shin, S.R. and Lee, D.W.. 2020. Seismic full-waveform inversion using decomposed P-wavefield. Journal of Seismic Exploration, 29: 201-224. Here we describe the development of a seismic full-waveform inversion method which employs P-wavefield decomposition to obtain accurate velocity information. Briefly, P-wavefield decomposition for multi-component data was performed with Helmholtz decomposition in elastic media and an objective function. To achieve efficient inversion, application of a back-propagation technique is essential. Therefore, a stress tensor was used for P-wavefield decomposition to allow application of a back- propagation technique. Our proposed inversion algorithm was validated with synthetic data obtained from the Marmousi2 velocity model which simulated an ocean bottom, multi-component survey. The subsurface information obtained with our inversion method was more accurate in regard to velocity and structure compared with a conventional elastic inversion method. In addition. the application of our inversion method to synthetic data simulating an ocean bottom seismometer survey which uses a small number of receivers also obtained better results in a numerical test.
