Paper presented at the SEG/AAPG International Meeting for Applied Geoscience & Energy, August 27–September 1, 2023
Paper Number: SEG-2023-3911716
... Seismic wavelet extraction is a crucial component of processes relating seismic data to reflectivity series, such as seismic-well-tie or seismic inversion. We propose a parameter-free Bayesian Variational Auto-Encoder (BVAE) wavelet extractor trained in a supervised manner on synthetically...
