• Researched and developed towards the Wave-Equation Based True-Amplitude Imaging correcting the wave propagation, acquisition geometry, and overburden effects:
• Researched effect of different amplitude correction terms especially that related to lateral velocity variation in ‘True-Amplitude’ One-Way Wave Propagator (TAOWP). Derived two types of asymptotic TAOWP: wide-angle.
• Proposed and developed an efficient scheme for one-way wave equation based local-angle domain (LAD) image illumination correction. Evaluated two local plane wave decomposition methods.
• Proposed and developed LAD full-wave illumination analysis for accurate acquisition design and true-amplitude imaging. Proposed and analyzed two local plane wave decomposing methods for full-wave illumination.
• Investigated influence of wave propagator amplitude correction and LAD illumination correction for true-amplitude imaging. Results showed illumination effect is much more significant than the former.

Investigated and illustrated using GOM Thunder Horse model the relative importance of low frequency and long offset in mitigating the non-linearity (cycle-skipping) of FWI, FWI’s capability for providing a good salt top, and multiples’ contribution in FWI. Results provided valuable information for future FWI applications and seismic acquisition design.
