Post-stack seismic data compression with multidimensional deep autoencoders
(Universidade Federal de Juiz de Fora (UFJF)BrasilICE – Instituto de Ciências ExatasPrograma de Pós-graduação em Ciência da ComputaçãoUFJF, 2020)
Simple and fast gradient-based impedance inversion using total variation regularization
(Geophysical Press, 2018-10)
We present an algorithm to estimate blocky images of the subsurface acoustic impedance (AI) from poststack seismic data. We regularize the resulting inverse problem, which is inherently ill-posed and non-unique, by means ...
Compressão de dados sísmicos pós-pilha usando uma rede adversária generativa com função de perda composta

Entropia de Tsallis aplicada à inversão sísmica
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2021-03-10)
The growing global energy demand has increasingly demanded resources from oil, in
this sense, the “easy exploration and production” reservoirs are running out. This has led to
numerous studies that make it possible to ...
Prestack Migration Velocity Analysis Using Time-remigration Trajectories
(EAGE Publishing BV, 2014)
A simple method inspired by empirical mode decomposition for denoising seismic data
(Society of Exploration Geophysicists, 2015-12)
We developed a new and simple method for denoising seismic data, which was inspired by data-driven empirical mode decomposition (EMD) algorithms. The method, which can be applied either as a trace-by-trace process or in ...
Edge-preserving frequency-offset denoising of seismic data
(Society of Exploration Geophysicists, 2018-09)
We have developed new algorithms for denoising 2D or 3D poststack seismic-amplitude data that use simple edge-preserving smoothing operators in the frequency-offset domain. The algorithms are aimed to attenuate random and ...
