Effective Constitutive Relations for Simulating CO2 Capillary Trapping in Heterogeneous Reservoirs with Fluvial Sedimentary Architecture
Naum I. Gershenzon, Robert W. Ritzi, David F. Dominic +1
Carbon dioxide (CO2) storage reservoirs commonly exhibit sedimentary architecture that reflects fluvial deposition. The heterogeneity in petrophysical properties arising from this…
Comparison of CO2 trapping in highly heterogeneous reservoirs with Brooks-Corey and van Genuchten type capillary pressure curves
Naum I. Gershenzon, Robert W. Ritzi, David F. Dominic +2
Geological heterogeneities essentially affect the dynamics of a CO2 plume in subsurface environments. Previously we showed how the dynamics of a CO2 plume is influenced by the mult…
How does the connectivity of open-framework conglomerates within multi-scale hierarchical fluvial architecture affect oil sweep efficiency in waterflooding?
Naum I. Gershenzon, Mohamad Reza Soltanian, Robert W. Ritzi +4
We studied the effects on oil sweep efficiency of the proportion, hierarchical organization, and connectivity of high-permeability open-framework conglomerate (OFC) cross-sets with…
A note on upscaling retardation factor in hierarchical porous media with multimodal reactive mineral facies
Mohamad Reza Soltanian, Robert Ritzi, Chaocheng Huang +2
We present a model for upscaling the time-dependent effective retardation factor in hierarchical porous media with multimodal reactive mineral facies. The model extends the approac…
Reactive solute transport in physically and chemically heterogeneous porous media with multimodal reactive mineral facies: The Lagrangian approach
Mohamad Reza Soltanian, Robert Ritzi, Zhenxue Dai +1
Physical and chemical heterogeneities have a large impact on reactive transport in porous media. Examples of heterogeneous attributes affecting reactive mass transport are the hydr…
Influence of small scale heterogeneity on CO2 trapping processes in deep saline aquifers
Naum I. Gershenzon, Mohamad Reza Soltanian, Robert W. Ritzi +1
The physical mechanism of CO2 trapping in porous media by capillary trapping (pore scale) incorporates a number of related processes, i.e. residual trapping, trapping due to hyster…
Understanding the Impact of Open-Framework Conglomerates on Water-Oil Displacements: Victor Interval of the Ivishak Reservoir, Prudhoe Bay Field, Alaska
Naum I. Gershenzon, Mohamadreza Soltanian, Robert W. Ritzi +1
The Victor Unit of the Ivishak Formation in the Prudhoe Bay Oilfield is characterized by high net-to-gross fluvial sandstones and conglomerates. The highest permeability is found w…
