Square-Root Variable Metric based elastic full-waveform inversion – Part 1: Theory and validation

, 2019
Full-waveform inversion (FWI) has become a powerful tool in inverting subsurface geophysical properties. The estimation of uncertainty in the resulting Earth models and parameter trade-offs, although equally important to the inversion result, has however

Efficient scattering approach to seismic full-waveform inversion in anisotropic elastic media with variable density [PDF]

This paper introduces a novel matrix-free approach for full waveform inversion in anisotropic elastic media, incorporating density variation through the utilization of the distorted Born iterative method. This study aims to overcome the computational and

Latent representation learning in physics-informed neural networks for full waveform inversion

Full waveform inversion (FWI), a state-of-the-art seismic inversion algorithm, comprises an iterative data-fitting process to recover high-resolution Earth’s properties (e.g., velocity).
