Dynamic Evolution of Pore-scale Heterogeneity and Transport Conditions Control Mineral Dissolution Regimes
Jinlei Wang, Yongfei Yang, Martin J. Blunt +1
Mineral dissolution in porous media is classically partitioned into static regimes within the Pe-Da plane, but this framework fails to capture the dissolution behavior of structura…
Time-Resolved Pore-Scale Imaging of Multiphase Dissolution during CO2-Saturated Brine Injection into a Carbonate: Competition between Hydrocarbon Mobilisation and Swelling
Qianqian Ma, Rukuan Chai, Zhuangzhuang Ma +3
We present time-resolved pore-scale experiments in which CO2-saturated brine was injected into a water-wet Ketton limestone sample containing residual hydrocarbon under reservoir c…
Intermittent two-phase flow in porous media: insights from pore-scale direct numerical simulation
Alexandra Karabasova, Sajjad Foroughi, Martin J. Blunt +1
Recent X-ray imaging experiments have revealed that multiphase flow through porous media involves transient fluctuations in local occupancy, even under fixed macroscopic steady-sta…
Pore-Scale Dynamics of Multiphase Reactive Transport in Water-Wet Carbonates under CO2-Acidified Brine Injection: Dissolution Patterns and Reaction Rates
Qianqian Ma, Rukuan Chai, Sajjad Foroughi +3
Depleted carbonate hydrocarbon reservoirs are promising sites for geological CO2 storage, yet the presence of residual hydrocarbons introduces complex pore-scale interactions that…
Percolation without trapping: how Ostwald ripening during two-phase displacement in porous media alters capillary pressure and relative permeability
Ademola Isaac Adebimpe, Sajjad Foroughi, Branko Bijeljic +1
Conventional measurements of two-phase flow in porous media often use completely immiscible fluids, or are performed over time-scales of days to weeks. If applied to the study of g…
