The microstructure of a porous medium and the physical characteristics of the solid and fluid phases determine the macroscopic transport properties of the medium. The purpose of this paper is to test numerical calculations of the geometrical and transport properties (electrical conductivity, permeability, specific surface area, and surface conductivity) of porous, permeable rocks, given their 3...

Abstract Image segmentation remains the most critical step in Digital Rock Physics (DRP) workflows, affecting analysis of physical rock properties. Conventional techniques struggle with numerous image artifacts and user bias, which lead to considerable uncertainty. This study evaluates advantages using random forest (RF) algorithm for fractured rocks. The quality is discussed compared two conve...

In this article, we present a numerical iterative method for the solution of internal viscous and incompressible flows in real porous three-dimensional bodies at their pore scale. We use penalized formulation problem involving velocity vorticity: an operator splitting allows to split apart diffusion (inherited from Stokes equation) penalization phenomena (which takes into account solid matrix)....

The objective of this study is to demonstrate the power of integrating rock physics theory, measurement and simulation to improve facies prediction in an unconventional limestone and shale reservoir. Reliable facies prediction is a challenge in unconventional reservoir characterization because of complex geological heterogeneities. Both deterministic and probabilistic approaches are commonly us...
