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…
Target-enclosing inversion using an interferometric objective function
Polina Zheglova, Matteo Ravasi, Ivan Vasconcelos +1
Full waveform inversion is a high-resolution subsurface imaging technique, in which full seismic waveforms are used to infer subsurface physical properties. We present a novel, tar…
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…
Characterizing the nonlinear interaction of S- and P-waves in a rock sample
Thomas Gallot, Alison Malcolm, Thomas L. Szabo +3
The nonlinear elastic response of rocks is known to be caused by the rocks' microstructure, particularly cracks and fluids. This paper presents a method for characterizing the nonl…
