Full-waveform Inversion

still under development …


Theory of FWI

  • Develop a unified Full-waveform Inversion platform with features of two and three dimensions, acoustic and elastic medium, and high-performance computing. image

Field-data Applications

  • Apply FWI on the wide-aperture land seismic dataset to reveal crustal structures and investigate the underlying tectonophysics. Study the optimal preprocessing & inversion workflow for field-data FWI applications. image

Velocity Models

Below list some useful velocity models for testing the FWI algorithms. More velocity models and open data can be found on the SEG website
