Stabilizing fluid-fluid displacements in porous media through wettability alteration

M Trojer, ML Szulczewski, R Juanes - Physical Review Applied, 2015 - APS
We study experimentally how wettability impacts fluid-fluid-displacement patterns in granular
media. We inject a low-viscosity fluid (air) into a thin bed of glass beads initially saturated …

Connectivity enhancement due to film flow in porous media

M Moura, EG Flekkøy, KJ Måløy, G Schäfer… - Physical Review …, 2019 - APS
We study the effects of connectivity enhancement due to film flow phenomena on the
drainage of an artificial porous medium and the relative influence of gravity for such effects …

Gravitational and finite‐size effects on pressure saturation curves during drainage

M Ayaz, R Toussaint, G Schäfer… - Water Resources …, 2020 - Wiley Online Library
We experimentally and numerically study the influence of gravity and finite‐size effects on
the pressure‐saturation relationship in a given porous medium during slow drainage. The …

Flow regime associated with vertical secondary migration

G Vasseur, X Luo, J Yan, D Loggia, R Toussaint… - Marine and petroleum …, 2013 - Elsevier
Secondary migration is defined as the movement of hydrocarbons through relatively
permeable rocks from source to trap: a two-phase flow within a porous medium. Depending …

Morphodynamics of fluid-fluid displacement in three-dimensional deformable granular media

MJ Dalbe, R Juanes - Physical Review Applied, 2018 - APS
We study experimentally the displacement of one fluid by another in a granular pack to
uncover relationships between fluid invasion and medium deformation. We develop an …

Intermittent dynamics of slow drainage experiments in porous media: Characterization under different boundary conditions

M Moura, KJ Måløy, EG Flekkøy, R Toussaint - Frontiers in Physics, 2020 - frontiersin.org
The intermittent dynamics of slow drainage flows in a porous medium is studied
experimentally. This kind of two-phase flow is characterized by a rich burst activity and our …

Mechanism of Pressure Difference Variations on Heavy Oil Start-Up and Percolation Effects

J Liu, H Yang, B Ou, J Du, Z Li, S Zhang, F Wu - ACS omega, 2024 - ACS Publications
To investigate the influence of pressure difference changes on the micro start-up and
percolation of heavy oil, a micro visualization displacement device was used to characterize …

Experimental and numerical studies of CO2 injection into water-saturated porous medium: capillary to viscous to fracture fingering phenomenon

A Islam, S Chevalier, M Sassi - Energy Procedia, 2013 - Elsevier
Injection of anthropogenic carbon dioxide (CO 2) into deep saline geological formations is a
possible long-term solution of removing CO 2 from the atmosphere. The early injection of CO …

Modeling of unsteady flow of viscous fluid in the channel of complex geometry

EA Marfin, AA Abdrashitov - IOP Conference Series: Materials …, 2016 - iopscience.iop.org
The article concerns an issue of exploring the mechanism of wave influence on the process
of filtration. To describe a filtration flow, the porous medium is represented as a capillary, the …

Visual analysis of immiscible displacement processes in porous media under ultrasound effect

K Naderi, T Babadagli - Physical Review E—Statistical, Nonlinear, and Soft …, 2011 - APS
The effect of sonic waves, in particular, ultrasonic radiation, on immiscible displacement in
porous media and enhanced oil recovery has been of interest for more than five decades …
