Enhanced dispersion in intermittent multiphase flow
Joachim Mathiesen, Gaute Linga, Marek Misztal +2
Transport in multiphase flow through porous media plays a central role in many biological, geological, and engineered systems. Here, we use numerical simulations of transport in im…
A minimal model for the onset of slip pulses in frictional rupture
Kjetil Thøgersen, Einat Aharonov, Fabian Barras +1
We present a minimal one-dimensional model for the transition from crack-like to pulse-like propagation of frictional rupture. In its non-dimensional form, the model depends on onl…
A minimal model for slow, sub-Rayleigh, super-shear and unsteady rupture propagation along homogeneously loaded frictional interfaces
Kjetil Thøgersen, Henrik Andersen Sveinsson, David Skålid Amundsen +3
In nature and experiments, a large variety of rupture speeds and front modes along frictional interfaces are observed. Here, we introduce a minimal model for the rupture of homogen…
Self-similar distributions of fluid velocity and stress heterogeneity in a dissolving porous limestone
Gaute Linga, Joachim Mathiesen, François Renard
In a porous rock, the spatial distribution of the pore space induces a strong heterogeneity in fluid flow rates and in the stress distribution in the rock mass. If the rock microst…
A 4D synchrotron X-ray tomography study of the formation of hydrocarbon migration pathways in heated organic-rich shale
Hamed Panahi, Maya Kobchenko, Francois Renard +6
Recovery of oil from oil shales and the natural primary migration of hydrocarbons are closely related processes that have received renewed interests in recent years because of the…
4D imaging of fracturing in organic-rich shales during heating
Maya Kobchenko, Hamed Panahi, Francois Renard +6
To better understand the mechanisms of fracture pattern development and fluid escape in low permeability rocks, we performed time-resolved in situ X-ray tomography imaging to inves…
