..., Kian Wei is serving as Senior Advisor for Low Carbon Solutions in Southeast Asia region (including Japan, South Korea and Taiwan) Abstract The emerging issues of natural carbon dioxide (CO 2 ) production alongside natural gas in Southeast Asian producing fields, presents challenges to well...

... Abstract Incomplete log data set and absence of critical subsurface information pose a major challenge in field development plan and reserves monetization. The urgency is heightened particularly when production has declined and requirement arisen to assess the impact of CO 2 concentration...

... Abstract An enhanced geothermal system that uses carbon dioxide (CO 2 ) for both reservoir creation and thermal energy extraction has been attracting attention in Japan. For this system, CO 2 fracturing is conducted to create highly permeable fractures in low-permeability reservoirs...

... Abstract The use of basaltic formations and existing wells in oil and gas fields for carbon dioxide (CO 2 ) mineralization holds both technical and economic advantages. However, these basaltic rocks have often undergone natural alteration, and their reactivity in CO 2 mineralization remains...

... on granite at conventional geothermal conditions using CO 2 instead of water because it has been suggested that the formation of the cloud-fracture network attributes primary to injection of the low-viscosity fluid (i.e., high-temperature water). Results in both fracturing experiments using water and CO 2...

... for extraction of geothermal energy. Presently, fracturing experiments have been carried out at similar conditions to examine feasibility of low-viscosity supercritical carbon dioxide (SC-CO 2 ) adoption for application at various geothermal conditions. In this study, three fracturing experiments were conducted...

.... Geological modeling is an important process to prove the suitable geologic formation in CCS project. The CO 2 plume behavior depends on geology structure of storage formation. This study focuses on geological modeling and the simulation of CO 2 plume behavior in saline sandstone of fluvial deposit, Nam...

... Abstract In this paper, an oil recovery process has been studied by injecting sodium metasilicate (Na 2 SiO 3 ·9H 2 O) solution to form blocking gel with CO 2 in larger permeability flow passes. The Na 2 SiO 3 ·9H 2 O solution is an alkali to reduce interfacial tension (IFT) reduction...
