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 …

Geological fracture zones play an important role in determining the amount of deposits in oil
and gas fields. In practice, for modeling wave scattering in fractured zones, numerical …

This paper considers numerical simulation of acoustic waves in heterogeneous two-
dimensional (2D) media by the grid-characteristic method. We present a novel high-order …

This paper presents a novel approach to modeling the propagation of seismic waves in a
medium containing subvertical fractured inhomogeneities, typical for mineralization zones …

Finite-difference (FD) methods approximate derivatives through a weighted summation of
function values from neighboring nodes. Traditionally, these neighboring nodes are …

We present a novel approach for constructing the training dataset for the Numerical
