Pore-scale network modeling can predict multiphase flow properties with arbitrary wetting conditions if the network represents the geology of the sample accurately. Such pore-scale modeling uses topologically disordered networks that realistically represent the pore structure. To generate the network it is first necessary to have a three-dimensional voxel-based pore-space representation that is...

Tight sandstone possesses multiscale pores. Capturing and modeling the important pore properties into a network for drainage is challenging computationally expensive. We present method of network, which enables us to handle huge rock micro computed tomography (μCT) images with high computational efficiency minimal experimental input data. This uses micro-links represent upscaled transport micro...

This study introduces PoreFlow, a pore-network modeling tool capable of simulating fluid flow and multi-component reactive and adsorptive transport under saturated and variably saturated conditions. PoreFlow includes a variety of modules, such as: pore network generator, drainage simulator, calculation of pressure and velocity distributions, and modeling of reactive solute transport accounting ...

Modeling and computing transport in the subsurface is a difficult problem that requires good understanding of the relations among different processes at various different length and time scales, and their effective properties. Already at the pore scale, ranging from a few micrometers to millimeters, direct flow simulation in a detailed medium geometry assuming Stokes flow is extremely costly. N...
