Localized Wavefield Inversion (LWI): an Adaptation of Multi-Block ADMM for Localized FWI
Hossein S. Aghamiry, Ali Gholami, Stephane Operto +1
Full-waveform inversion (FWI) is a high-resolution and computationally intensive imaging technique to reconstruct unknown parameters in the computational model in which the waves p…

ADMM-based full-waveform inversion for microseismic imaging
Hossein S. Aghamiry, Ali Gholami, Stéphane Operto +1
Full waveform inversion (FWI) is beginning to be used to characterize weak seismic events at different scales, an example of which is microseismic event (MSE) characterization. How…

Vector acoustic full waveform inversion: taking advantage of de-aliasing and receiver ghosts
Polina Zheglova, Alison Malcolm
Data acquisition is changing to incorporate more components of the recorded wavefield. An example of this is so-called vector data in which both the pressure and particle velocity…
