Bayesian weighted time-lapse full-waveform inversion using a receiver-extension strategy
Sergio Luiz E. F. da Silva, Ammir Karsou, Roger M. Moreira +1
Time-lapse full-waveform inversion (FWI) has become a powerful tool for characterizing and monitoring subsurface changes in various geophysical applications. However, non-repeatabi…
Refraction FWI of a circular shot OBN acquisition in the Brazilian pre-salt region
Sérgio Luiz E. F. da Silva, Felipe T. Costa, Ammir Karsou +5
We develop a workflow based on full-waveform inversion (FWI) to estimate P-wave velocities in a deepwater Brazilian pre-salt field using the recently introduced circular shot ocean…
A graph-space optimal transport FWI approach based on κ-generalized Gaussian distribution
Sérgio Luiz E. F. da Silva, G. Kaniadakis
The statistical basis for conventional full-waveform inversion (FWI) approaches is commonly associated with Gaussian statistics. However, errors are rarely Gaussian in non-linear p…
