Abstract
- We analyzed 2-D seismic and well-log data from the southern Jeju Basin, offshore southern Korea, northern East China Sea to estimate the CO2 storage capacity of the structural traps in the area. Sand intervals with > 10-m gross thickness were identified from the gamma-ray logs and their porosity was estimated from the neutron logs corrected for the shale effect. A total of 14 structural closures was delineated from the depth-converted maps of the sand intervals. Seismic inversion and multi-attribute transform were performed to predict the reservoir quality (i.e., porosity) of the closures away from the well control. The total storage capacity of the closures was estimated from the deterministic, volumetric method, based on the published storage efficiency parameters. The estimated CO2 storage capacity for the 14 closures is about 302 Mt, comparable to the CO2 emission (ca. 530 Mt) of Korea in 2009.
