Multiphase Reactive Transport in a Heterogeneous Flow Field: Channel Formation in Hydrocarbon-Bearing Carbonate Rock
Qianqian Ma, Zhuangzhuang Ma, Rukuan Chai +3
Carbon capture, utilization and storage (CCUS) is a key approach for reducing anthropogenic CO2 emissions. Currently the vast majority of CO2 stored is injected into depleted hydro…
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…
Time-dependent pore-network modelling of Ostwald ripening in porous media
Ademola Isaac Adebimpe, Sajjad Foroughi, Branko Bijeljic +1
We present a time-dependent pore-network model that couples transient mass transfer in the aqueous phase, capillary pressure heterogeneity, and realistic pore-throat geometries to…
