Summary Stochastic approaches for inverting geophysical data have many advantages over deterministic inversion methods in terms of finding global solutions and quantifying their associated uncertainty. Since stochastic methods often need to run forwa

International audience; In tropical and sub-tropical mixed siliciclastic–carbonate depositional systems, fluvial input and in situ neritic carbonate interact over space and time. Despite being the subject of many studies, controls on partitioning o

Despite the importance of channel avulsion in constructing fluvial stratigraphy, it is unclear how contrasting avulsion processes are reflected in stratigraphic-stacking patterns of channelized fluvial sand bodies, as a proxy for how river depocenter

A numerical model of two-phase flow at the micro-scale using the volume-of-fluid method

Autor: Branko Bijeljic, Martin J. Blunt, Ali Q. Raeini, Mosayeb Shams

Publikováno v: Journal of Computational Physics. 357:159-182

This study presents a simple and robust numerical scheme to model two-phase flow in porous media where capillary forces dominate over viscous effects. The volume-of-fluid method is employed to capture the fluid-fluid interface whose dynamics is expli

Microstructural imaging and characterization of oil shale before and after pyrolysis

Autor: Qingyang Lin, Branko Bijeljic, Tarik Saif, Martin J. Blunt

Publikováno v: Fuel. 197:562-574

The microstructural evaluation of oil shale is challenging which demands the use of several complementary methods. In particular, an improved insight into the pore network structure and connectivity before, during, and after oil shale pyrolysis is cr
