Data-driven suppression of short-period multiples from laterally varying thin-layered overburden structures Open
Marchenko multiple elimination methods remove all orders of overburden-generated internal multiples in a data-driven way. In the presence of thin beds, however, these methods have been shown to underperform. This is because the underlying …

Modeling and data-driven isolation of two-way wavefield constituents Open
Synthesizing individual wavefield constituents (such as primaries, first-order scattering, and free-surface or internal multiples) is important in the development of seismic data processing algorithms, for instance, for seismic multiple re…

Data-driven control over short-period internal multiples in media with a horizontally layered overburden Open
SUMMARY Short-period internal multiples, resulting from closely spaced interfaces, may interfere with their generating (bandlimited) primaries, and hence they pose a long-standing challenge in their prediction and removal. A recently propo…

Marchenko-based immersive wave simulation Open
Seismic modelling and inversion often require the calculation of many closely related forward problems. If model perturbations are restricted to a small subvolume, a local wave solver can be an efficient alternative to a wave simulation pe…
