Multipliers waveform inversion
Ali Gholami, Hossein S. Aghamiry, Stéphane Operto
The full-waveform inversion (FWI) addresses the computation and characterization of subsurface model parameters by matching predicted data to observed seismograms in the frame of n…
Accurate 3D frequency-domain seismic wave modeling with the wavelength-adaptive 27-point finite-difference stencil: a tool for full waveform inversion
Hossein S. Aghamiry, Ali Gholami, Laure Combe +1
Efficient frequency-domain Full Waveform Inversion (FWI) of long-offset/wide-azimuth node data can be designed with a few discrete frequencies. However, 3D frequency-domain seismic…
Anderson accelerated augmented Lagrangian for extended waveform inversion
Kamal Aghazade, Ali Gholami, Hossein S Aghamiry +1
The augmented Lagrangian (AL) method provides a flexible and efficient framework for solving extended-space full-waveform inversion (FWI), a constrained nonlinear optimization prob…
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…
Efficient extended-search space full-waveform inversion with unknown source signatures
Hossein S. Aghamiry, Frichnel W. Mamfoumbi-Ozoumet, Ali Gholami +1
Full waveform inversion (FWI) requires an accurate estimation of source signatures. Due to the coupling between the source signatures and the subsurface model, small errors in the…
