Bayesian tomography using polynomial chaos expansion and deep generative networks
Giovanni Angelo Meles, Macarena Amaya, Shiran Levy +2
Implementations of Markov chain Monte Carlo (MCMC) methods need to confront two fundamental challenges: accurate representation of prior information and efficient evaluation of lik…
Design, implementation and application of the Marchenko Plane-wave algorithm
Jan Thorbecke, Mohammed Almobarak, Johno van IJsseldijk +3
The Marchenko algorithm can suppress the disturbing effects of internal multiples that are present in seismic reflection data. To achieve this, a set of coupled equations with four…
On the retrieval of forward-scattered waveforms from acoustic reflection and transmission data with the Marchenko equation
Joost van der Neut, Joeri Brackenhoff, Giovanni Meles +3
A Green's function in an acoustic medium can be retrieved from reflection data by solving a multidimensional Marchenko equation. This procedure requires a-priori knowledge of the i…
Bayesian tomography with prior-knowledge-based parametrization and surrogate modeling
Giovanni Angelo Meles, Niklas Linde, Stefano Marelli
We present a Bayesian tomography framework operating with prior-knowledge-based parametrization that is accelerated by surrogate models. Standard high-fidelity forward solvers solv…
3D Marchenko applications: implementation and examples
Joeri Brackenhoff, Jan Thorbecke, Giovanni Meles +3
We implement the 3D Marchenko equations to retrieve responses to virtual sources inside the subsurface. For this, we require reflection data at the surface of the Earth that contai…
A proposal for Marchenko-based target-oriented full waveform inversion
S. M. Aydin Shoja, Giovanni A. Meles, Kees Wapenaar
The Hessian matrix plays an important role in correct interpretation of the multiple scattered wave fields inside the FWI frame work. Due to the high computational costs, the compu…
Data-driven retrieval of primary plane-wave responses
Giovanni Angelo Meles, Lele Zhang, Jan Thorbecke +2
Seismic images provided by reverse time migration can be contaminated by artefacts associated with the migration of multiples. Multiples can corrupt seismic images, producing both…
Wavefield Finite Time Focusing with Reduced Spatial Exposure
Giovanni Angelo Meles, Joost van der Neut, Koen W. A. van Dongen +1
Wavefield focusing is often achieved by Time-Reversal Mirrors, where wavefields emitted by a source located at the focal point are evaluated at a closed boundary and sent back, aft…
Virtual plane-wave imaging via Marchenko redatuming
Giovanni Angelo Meles, Kees Wapenaar, Jan Thorbecke
Marchenko redatuming is a novel scheme used to retrieve up- and down-going Green's functions in an unknown medium. Marchenko equations are based on reciprocity theorems and are der…
