IntraSeismic: a coordinate-based learning approach to seismic inversion

no code implementations17 Dec 2023 Juan Romero, Wolfgang Heidrich, Nick Luiken, Matteo Ravasi

Seismic imaging is the numerical process of creating a volumetric representation of the subsurface geological structures from elastic waves recorded at the surface of the Earth.

Data Compression Seismic Imaging +2

Posterior sampling with CNN-based, Plug-and-Play regularization with applications to Post-Stack Seismic Inversion

no code implementations30 Dec 2022 Muhammad Izzatullah, Tariq Alkhalifah, Juan Romero, Miguel Corrales, Nick Luiken, Matteo Ravasi

However, selecting appropriate prior information in a probabilistic inversion is crucial, yet non-trivial, as it influences the ability of a sampling-based inference in providing geological realism in the posterior samples.

Decision Making Seismic Inversion +2

A hybrid approach to seismic deblending: when physics meets self-supervision

no code implementations30 May 2022 Nick Luiken, Matteo Ravasi, Claire E. Birnie

Compressed sensing type regularization is then applied, where sparsity in some domain is assumed for the signal of interest.
