CO2 Convective Dissolution in Oil-Saturated Unconsolidated Porous Media at Reservoir Conditions
Amarasinghe, Widuramina; Fjelde, Ingebret; Giske, Nils Harald; Guo, Ying (Peer reviewed; Journal article, 2021)During CO2 storage, CO2 plume mixes with the water and oil present at the reservoir, initiated by diffusion followed by a density gradient that leads to a convective flow. Studies are available where CO2 convective mixing ... -
CO2 Dissolution and Convection in Oil at Realistic Reservoir Conditions: A Visualization Study.
Amarasinghe, Widuramina Sameendranath; Fjelde, Ingebret; Guo, Ying (Peer reviewed; Journal article, 2021)CO2 convective mixing has been extensively studied for CO2 dissolution in saline water but very limited with the presence of oil. The objective of this work was to visually study the supercritical CO2 (sCO2) dissolution ... -
Effects of permeability on CO2 dissolution and convection at reservoir temperature and pressure conditions: A visualization study
Amarasinghe, Widuramina Sameendranath; Fjelde, Ingebret; Guo, Ying; Rydland, Jan-Åge (Peer reviewed; Journal article, 2020)When CO2 is injected into aquifers, CO2 will dissolve into the water phase. CO2 dissolution initiated by diffusion, will increase the density of the water phase and thereby commence the convective flow of CO2. The objective ... -
Integrated Approach to Reservoir Simulations for Evaluating Pilot CO<inf>2</inf> Injection in a Depleted Naturally Fractured Oil Field On-Shore Europe
Pagáč, Milan; Opletal, Vladimír; Shchipanov, Anton; Nermoen, Anders; Berenblyum, Roman; Fjelde, Ingebret; Rez, Jiří (Journal article; Peer reviewed, 2024)Carbon dioxide capture and storage (CCS) is a necessary requirement for high-emitting CO2 industries to significantly reduce volumes of greenhouse gases released into the atmosphere and mitigate climate change. Geological ... -
Periodic CO2 Injection for Improved Storage Capacity and Pressure Management under Intermittent CO2 Supply
Shchipanov, Anton; Kollbotn, Lars; Encinas, Mauro; Fjelde, Ingebret; Berenblyum, Roman (Peer reviewed; Journal article, 2022)Storing CO2 in geological formations is an important component of reducing greenhouse gases emissions. The Carbon Capture and Storage (CCS) industry is now in its establishing phase, and if successful, massive storage ... -
The Role of the Mineralogical Composition on Wettability via Flotation Test and Surface Complexation Modeling (SCM)
Erzuah, Samuel; Fjelde, Ingebret; Omekeh, Aruoture Voke (Peer reviewed; Journal article, 2024)Minerals are the chief constituents of rocks and have varied properties, such as the surface area, surface charge, site density, etc. Hence, numerous interactions are bound to occur in a reservoir during rock–fluid (i.e., ... -
Surface Complexation Modelling of Wettability Alteration during Carbonated Water Flooding
Mehdiyev, Fagan; Erzuah, Samuel; Omekeh, Aruoture Voke; Fjelde, Ingebret (Peer reviewed; Journal article, 2022)CO2 capture and utilization is an effective tool in reducing greenhouse gas emissions and hence, combating global warming. In the present study, surface complexation modeling (SCM) with the geochemistry solver, PHREEQ-C, ... -
Visual investigation of CO2 dissolution and convection in heterogeneous porous media at reservoir temperature and pressure conditions
Amarasinghe, Widuramina Sameendranath; Fjelde, Ingebret; Flaata, Anna Maija Nørstebø (Peer reviewed; Journal article, 2021)CO2 convective mixing in saline aquifers has been widely studied numerically and experimentally. Reservoir heterogeneity is significant for CO2 convective mixing and experimental studies are still limited. In this study, ...
