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
Fjelde, Ingebret; Guo, Ying; Rydland, Jan-Åge; Amarasinghe, Widuramina (Peer reviewed; Journal article, 2020-06)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 ... -
Simulation of Water Management Processes
Nygård, Jan Inge (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Conformance control practices are commonly used to tackle issues related with injected fluids bypassing potentially oil-bearing formations, due to the presence of conductive fractures. To improve the prospect of such a ... -
A Visual Investigation of CO2 Convective Mixing in Water and Oil at the Pore Scale Using a Micromodel Apparatus at Reservoir Conditions
Amarasinghe, Widuramina Sameendranath; Farzaneh, Seyed; Fjelde, Ingebret; Sohrabi, M; Guo, Ying (Peer reviewed; Journal article, 2021-01)CO2 convective mixing in water has been visualized in Hele-Shaw and PVT cell experiments but not at the pore scale. Furthermore, CO2 convective mixing in a three-phase system (i.e., CO2 in the presence of both water and ...
