DOI: 10.1093/gji/ggy432
Abstract: We investigate the performance of the individual 2-D elastic full-waveform inversion (FWI) of Rayleigh and Love waves as well as the feasibility of a simultaneous joint FWI of both wave types. The FWI of surface… read more here.

DOI: 10.1109/lgrs.2022.3178915
Abstract: Affected by the low-frequency seismic data missing and multiple parameters coupling, elastic full waveform inversion (EFWI) is easy to fall into local minima. This letter attempts to solve the local minima problem from two aspects:… read more here.

DOI: 10.1190/geo2018-0685.1
Abstract: Obtaining high-resolution models of the earth, especially around the reservoir, is crucial to properly image and interpret the subsurface. We have developed a regularized elastic full-waveform inversion (FWI) method that uses facies as the prior… read more here.
