Marchenko focusing and imaging are novel methods for correctly handling multiple scattered energy while processing seismic data. However, strict requirements in the acquisition geometry, specifically the colocation of sources and receivers as well as

We present a fundamentally new approach to laboratory acoustic and seismic wave experimentation that enables full immersion of a physical wave propagation experiment within a virtual numerical environment. Using a recent theory of immersive boundary

In numerical modelling of wave propagation, the finite-difference (FD) injection method enables the re-introduction of simulated wavefields in model subdomains with machine precision, enabling the efficient calculation of waveforms after localized mo

Many applications in computational geophysics involve the modeling of seismic wave propagation on a set of closely related subsurface models. In such scenarios, it is of interest to recompute the seismic wavefields locally (only in the regions of cha

Imaging a target zone and analyzing its corresponding velocities using seismic surface data can be challenging, in particular if the target zone is located below a highly scattering overburden. Marchenko redatuming enables the redatuming of the surfa

Summary Geophysics aims at understanding the structure of the Earth from physical measurements. Due to the complexity and dimensions of the subsurface, geophysicists are required to handle very large observational datasets and to perform intensive co

We present an imaging method that creates a map of reflection coefficients in correct one-way time with no contamination from internal multiples using purely a filtering approach. The filter is computed from the measured reflection response and does
