Estimating permeability from thin sections without reconstruction: Digital rock study of 3D properties from 2D images

TL;DR: A novel reference dataset is generated to quantify the impact of numerical solvers, boundary conditions, and simulation platforms on permeability of microstructures ranging from idealized pipes to digital rocks and finds that more stringent convergence criteria can improve solver accuracy but at the expense of longer computation time.

TL;DR: A Bayesian framework to quantify the absolute permeability of water in a porous structure from the geometry and clustering parameters of its underlying pore-throat network, using a Database of Micro Networks for micro-scale porous structures as main input stream for the proposed Bayesian scheme.

TL;DR: Empirical relation can over‐estimate permeability by a magnification of 50 or more, particularly for those strong heterogeneous structures reported in this study, Nevertheless, empirical relation is still applicable for artificial rocks.

TL;DR: The effectiveness of the models, in predicting a petrology class in a thin section, strongly correlates with the amount of labeled data available to train the model to interpret the class in question.

TL;DR: In this article, a general technique for simulating solid-fluid suspensions is described, which combines Newtonian dynamics of the solid particles with a discretized Boltzmann equation for the fluid phase; the many-body hydrodynamic interactions are fully accounted for, both in the creeping flow regime and at higher Reynolds numbers.

TL;DR: In this paper, extensive numerical tests of the method are described; results are presented for creeping flows, both with and without Brownian motion, and at finite Reynolds numbers, and the short-time dynamics of random dispersions of up to 1024 colloidal particles have been simulated.
