Latest Patents
Jiawei Mei's latest patents include a "System and method for elastic full waveform inversion and imaging." This innovative method involves seismic imaging of subsurface structures using full waveform inversion (FWI). The process begins with obtaining an initial P-velocity model that describes seismic wave propagation through the subsurface. It continues with generating an S-velocity model, creating an elastic synthetic dataset, and updating the P-velocity model based on comparisons with recorded seismic data. The ultimate goal is to generate a detailed image of the subsurface based on reflectivity.
Another significant patent is focused on "Methods using travel-time full waveform inversion for imaging subsurface formations with salt bodies." This patent outlines improved FWI techniques for seismic exploration, particularly in areas with salt bodies. The methods utilize a travel-time cost function, where time-shifts are weighted using cross-correlation coefficients of recorded and synthetic data. These enhancements aim to produce clearer images while mitigating issues such as cycle-skipping and amplitude discrepancies.
