Extension of Vertical Equilibrium Model for Two-Phase Displacement in Layer-Cake Reservoirs: Accounting for Water-CO2 Partial Miscibility and Fines Migration
Kofi Ohemeng Kyei Prempeh, Pavel Bedrikovetsky, Rouhi Farajzadeh
Numerical simulations of geological CO2 storage in deep saline aquifers have demonstrated that vertical equilibrium (VE) models offer a robust and computationally efficient framewo…

Long-term propagation of CO2 plume below the seal accounting for chemical reactions and water counter-flow
Amin Shokrollahi, Syeda Sara Mobasher, Kofi Ohemeng Kyei Prempeh +3
Accurate prediction of long-term CO2 plume migration beneath seals is crucial for the viability of CO2 storage in deep saline aquifers. Groundwater counterflow and chemical reactio…

Two-phase immiscible displacement of water by gas accounting for fines migration: analytical model for vertical equilibrium
Amin Shokrollahi, Kofi Ohemeng Kyei Prempeh, Syeda Sara Mobasher +2
Fines migration during subterranean CO2 storage is considered as one of major contributors to formation damage and injectivity decline. The main formation damage mechanism by migra…
