In carbon capture and storage (CCS), CO(2) is captured at power plants and then injected underground into reservoirs like deep saline aquifers for long-term storage. While CCS may be critical for the continued use of fossil fuels in a carbon-constrained world, the deployment of CCS has been hindered by uncertainty in geologic storage capacities and(More)

We study the displacement of immiscible fluids in deformable, noncohesive granular media. Experimentally, we inject air into a thin bed of water-saturated glass beads and observe the invasion morphology. The control parameters are the injection rate, the bead size, and the confining stress. We identify three invasion regimes: capillary fingering, viscous(More)

Your story matters. 8 The geologic sequestration of carbon dioxide (CO 2) in structural and stratigraphic 9 traps is a viable option to reduce anthropogenic emissions. While dissolution of the 10 CO 2 stored in these traps reduces the long-term leakage risk,(More)

Abstract The effect of flow instabilities on capillary trapping mechanisms is a major source of uncertainty in CO 2 sequestration in deep saline aquifers. Standard macroscopic models of multiphase flow in porous media are unable to explain(More)
We study the gravity-exchange flow of two immiscible fluids in a porous medium and show that, in contrast with the miscible case, a portion of the initial interface remains pinned at all times. We elucidate, by means of micromodel experiments, the pore-level mechanism responsible for capillary pinning at the macroscale. We propose a sharp-interface(More)
The emergence of scaling in transport through interconnected systems is a consequence of the topological structure of the network and the physical mechanisms underlying the transport dynamics. We study transport by advection and diffusion in scale-free and Erdos-R6nyi networks. Using stochastic particle simulations, we find anomalous (nonlinear) scaling of(More)
