A Coarsening Approach to the Troll Aquifer Model
David Landa-Marbán, Tor Harald Sandve, Sarah Eileen Gasda
Effective management of pressure communication and interference between concurrent CO storage operations is essential for the development of gigaton-scale storage hubs. Coarse…
Impact of deformation bands on fault-related fluid flow in field-scale simulations
Runar L. Berge, Sarah E. Gasda, Eirik Keilegavlen +1
Subsurface storage of CO2 is predicted to rise exponentially in response to the increasing levels of CO2 in the atmosphere. Large-scale CO2 injections into the subsurface require u…
Numerical studies of long-term wettability alteration effects in CO storage applications
David Landa-Marbán, Kundan Kumar, Sarah Eileen Gasda +2
The wettability of the rock surface in porous media has an effect on the constitutive saturation functions that govern capillary pressure and relative permeability. The term wettab…
Field-scale impacts of long-term wettability alteration in geological CO storage
Abay Kassa, Sarah Eileen Gasda, David Landa-Marbán +2
Constitutive functions that govern macroscale capillary pressure and relative permeability are central in constraining both storage efficiency and sealing properties of CO stor…
Numerical studies of CO leakage remediation by micp-based plugging technology
David Landa-Marbán, Kundan Kumar, Svenn Tveit +1
Microbially induced calcite precipitation (MICP) is a technology for sealing leakage paths to ensure the safe storage of CO in geological formations. In this work we introduce…
Practical approaches to study microbially induced calcite precipitation at the field scale
David Landa-Marbán, Svenn Tveit, Kundan Kumar +1
Microbially induced calcite precipitation (MICP) is a new and sustainable technology which utilizes biochemical processes to create barriers by calcium carbonate cementation; there…
Modeling of relative permeabilities including dynamic wettability transition zones
Abay M. Kassa, Sarah E. Gasda, K. Kumar +1
Wettability is a pore-scale property that impacts the relative movement and distribution of fluids in a porous medium. There are reservoir fluids that provoke the surface within po…
Implicit linearization method for non-standard two-phase flow in porous media
Abay M. Kassa, Kundan Kumar, Sarah E. Gasda +1
In this paper, we consider a non-local (in time) two-phase flow model. The non-locality is introduced through the wettability alteration induced dynamic capillary pressure function…
Impact of Time-Dependent Wettability Alteration on the Dynamics of Capillary Pressure
Abay M. Kassa, Sarah E. Gasda, K. Kumar +1
Wettability is a pore-scale property that has an important impact on capillarity, residual trapping, and hysteresis in porous media systems. In many applications, the wettability o…
Modelling Geomechanical Impact of CO2 Injection Using Precomputed Response Functions
Odd Andersen, Halvor M. Nilsen, Sarah E. Gasda
When injecting CO2 or other fluids into a geological formation, pressure plays an important role both as a driver of flow and as a risk factor for mechanical integrity. The full ef…
