Does 3D frequency-domain FWI of full-azimuth/long-offset OBN data feasible? The Gorgon case study
S. Operto, P. Amestoy, H. S. Aghamiry +13
Frequency-domain Full Waveform Inversion (FWI) is potentially amenable to efficient processing of full-azimuth long-offset stationary-recording seabed acquisition carried out with…
Wave simulation in non-smooth media by PINN with quadratic neural network and PML condition
Yanqi Wu, Hossein S. Aghamiry, Stephane Operto +1
Frequency-domain simulation of seismic waves plays an important role in seismic inversion, but it remains challenging in large models. The recently proposed physics-informed neural…
On the connection between WRI and FWI: Analysis of the nonlinear term in the Hessian matrix
Ali Gholami, Hossein S. Aghamiry, Stephane Operto
Implementation of the standard full waveform inversion (FWI) poses difficulties as the initial model offsets from the true model. The wavefield reconstruction inversion (WRI) was p…
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…
Large-scale highly-accurate extended full waveform inversion using convergent Born series
Hossein S. Aghamiry, Ali Gholami, Kamal Aghazade +2
Full-waveform inversion (FWI) is a seismic imaging method that provides quantitative inference about subsurface properties with a wavelength-scale resolution. Its frequency-domain…
