Pore-scale dissolution of CO2+ SO2 in deep saline aquifers

S Ovaysi, M Piri - International Journal of Greenhouse Gas Control, 2013 - Elsevier
We employ Modified Moving Particle Semi-implicit (MMPS) method to study the multi-ion
transport of CO2 and SO2 in natural porous media at the pore level. A new approach has …

Quantifying the representative size in porous media

S Ovaysi, MF Wheeler, M Balhoff - Transport in porous media, 2014 - Springer
We present a new approach to quantify the representative quality of pore-scale samples of
porous media. It is shown that the flow field uniformity serves as a reliable criterion to decide …

Pore‐space alteration induced by brine acidification in subsurface geologic formations

S Ovaysi, M Piri - Water Resources Research, 2014 - Wiley Online Library
A new Lagrangian particle‐based method is presented to simulate reactive transport in
natural porous media. This technique is based on Modified Moving Particle Semi‐implicit …

[PDF][PDF] Mass transfer through porous media: Sub-pore scale modeling approach

S Taheri - University of Calgary, Calgary, Alberta, 2013 - prism.ucalgary.ca
An important feature of the miscible fluid displacement is the mixing of the solvent and oil.
This mixing occurs on the microscopic scale. The mixing has positive and negative effects …

Direct Pore-Scale Modeling of Flow and Transport in Tight Formations

S Ovaysi, M Piri - Unconventional Resources Technology …, 2013 - library.seg.org
URTeC 1582416 A direct pore-scale modeling technique is developed to study flow and
transport in naturally-occurring tight formations. The model takes as input high-resolution x …
