We analyze the problem of a heterogeneous formulation of the equation of motion and
propose a new 3D fourth-order staggered-grid finite-difference (FD) scheme for modeling …

Surface topography has been considered a difficult task for seismic wave numerical
modelling by the finite-difference method (FDM) because the most popular staggered finite …

In order to study the effect of the micro‐CT scan resolution and size on the accuracy of
upscaled digital rock property estimation of core samples Bentheimer sandstone images …

The numerical modeling of mechanical waves is currently a fundamental tool for the study
and investigation of their propagation in media with heterogeneous physical properties …

High-order staggered-grid finite-difference (SFD) schemes are preferred in elastic wave
simulation for geophysical problems because they decrease the accumulation of error from …

Numerical simulations of wave propagation produce different errors and the most well
known is numerical dispersion, which is only valid for homogeneous media. However, there …

We have developed a novel approach for seismic modeling combining conventional finite
differences with deep neural networks. The method includes the following steps. First, a …

We present an algorithm for the numerical simulation of seismic wave propagation in models
with a complex near surface part and free surface topography. The approach is based on the …

This paper presents an original approach to local time–space grid refinement for the
numerical simulation of wave propagation in models with localized clusters of micro …

Seismic attenuation mechanisms receive increasing attention for the characterization of
fractured formations because of their inherent sensitivity to the hydraulic and elastic …
