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…
Target-oriented full-waveform inversion based on generalized Rényi entropy using patched Green's function techniques
Wagner A. Barbosa, Sérgio Luiz E. F. da Silva, Erick de la Barra +1
The estimation of physical parameters from data analysis is a crucial point for the description and modeling of many complex systems. Based on Rényi -Gaussian distribution and p…
Generalized statistics: applications to data inverse problems with outlier-resistance
João V. T. de Lima, Sérgio Luiz E. F. da Silva, João M. de Araújo +2
The conventional approach to data-driven inversion framework is based on Gaussian statistics that presents serious difficulties, especially in the presence of outliers in the measu…
An outlier-resistant -generalized approach for robust physical parameter estimation
Sérgio Luiz E. F. da Silva, R. Silva, Gustavo Z. dos Santos Lima +2
In this work we propose a robust methodology to mitigate the undesirable effects caused by outliers to generate reliable physical models. In this way, we formulate the inverse prob…
