An overview of full-waveform inversion in exploration geophysics
Jean Virieux,Stéphane Operto +1 more
TL;DR: This review attempts to illuminate the state of the art of FWI by building accurate starting models with automatic procedures and/or recording low frequencies, and improving computational efficiency by data-compression techniquestomake3DelasticFWIfeasible.
Journal ArticleDOI
Seismic imaging of complex onshore structures by 2D elastic frequency-domain full-waveform inversion
TL;DR: In this paper, the authors evaluated different multiscale strategies with the aim of mitigating the nonlinearities of the elastic properties of the subsurface at depth for civil engineering applications and oil and gas-reservoir characterization.
Journal ArticleDOI
Multiscale imaging of complex structures from multifold wide-aperture seismic data by frequency-domain full-waveform tomography: application to a thrust belt
TL;DR: In this article, the waveform modeling and tomography are implemented in the frequency domain and solved with a finite-difference method applied to the visco-acoustic wave equation.
Journal ArticleDOI
A guided tour of multiparameter full-waveform inversion with multicomponent data: From theory to practice
Stéphane Operto,Y. Gholami,V. Prieux,Alessandra Ribodetti,Romain Brossier,Ludovic Métivier,Jean Virieux +6 more
TL;DR: In this paper, the authors proposed a multiameter full waveform inversion (FWI) model of the subsurface of the seismic wave propagation in visco-elastic media.
Journal ArticleDOI
3D finite-difference frequency-domain modeling of visco-acoustic wave propagation using a massively parallel direct solver: A feasibility study
Stéphane Operto,Jean Virieux,Patrick R. Amestoy,Jean-Yves L'Excellent,Luc Giraud,Hafedh Ben Hadj Ali +5 more
TL;DR: In this paper, an optimal 3D finite-difference stencil for frequency-domain modeling is presented, which is based on a parsimonious staggered-grid method for 3D visco-acoustic wave propagation modeling.
