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 ... -
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 ... -
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, ...
