- Center for CO2 Geological Storage
The Oil & Gas Research Center focuses on the interpretation of geophysical and geological data, assessment of petroleum resources in sedimentary basins and fields, and development of petroleum production techniques. These efforts have realized significant contribution to securing national petroleum resources. The Center has been conducting assessment of gas hydrate resources in the Korean offshore and developing safe and dependable technologies from gas hydrate reservoirs that secures gas hydrates as future energy resources. Recent R&D projects focus on the evaluation of unconventional resources, which include shale gas, coal bed methane, tight gas and oil sand, in cooperation with KNOC and KOGAS. The research interests further expand to such challenging issues as carbonate reservoir characterization, CO2 EOR, and BT/NT fusion technology for enhancing oil recovery.

The Marine Geology and Geophysical Exploration Research Center is conducting multidisciplinary marine geoscience research and develops world-class technologies for exploration of natural resources using Korea's only geophysical research vessel Tamhae II. The Center also has other missions, including acquisition of marine geological information around the Korean seas, identification of potential areas of submarine mineral and energy resources, and studies on global environmental changes. The marine geological information acquired from coastal and marine geological surveys around the Korean seas is collected and used for publishing various marine geological and geophysical thematic maps. Marine geological information is also used for systematic marine spatial planning, prediction of coastal geo-hazards, and establishment of CO2 storage plans. The 3D seismic research vessel, Tamhae II, efficiently performs marine geophysical researches including high-resolution seismic reflection/refraction in 2D/3D, OBS/OBC (Ocean Bottom Seismometers/Ocean Bottom Cable) and gravity/magnetics surveys. Processing, analysis, and interpretation of these data helps explore domestic and overseas oil and gas resources, research CO2 storage, analyze coastal geo-hazards, and delimitate continental shelf boundaries. The Center is conducting civil-military integration researches, such as marine subsurface geo-acoustic studies, studies on physical properties and classification of seafloor sediments, and global marine geological and geophysical cooperative researches through participation in the Integrated Ocean Drilling Program (IODP). The Marine Core Center operates up-to-date equipment and facilities, including the largest sediment sample storage in Korea equipped with constant temperature and humidity control. The Center is carrying out wide-range researches based on the core with a special focus on detailed analysis of core samples of marine sediments and maintaining their database.

Center for CO2 Geological Storage conducts fundamental research on geological storage of CO2 and develops key technologies for ensuring safe, cost-effective large-scale applications. Fundamental researches focus on geological characterization and storage capacity assessment at a site-scale and enabling large-scale CO2 storage in offshore areas of Korea. Several researches, based on lab and field experiments, have been carried out to find methods that help overcome technical barriers in implementation of large-scale offshore CO2 storage projects. Main R&D activities are 1) development of the on-site CO2 monitoring technology with laboratory experiments, as well as small-scale test bed, 2) estimation of CO2 storage capacity for sub-basalt formation in the South Sea of Korea, 3) CO2-water-rock interaction experiments and two-phase (CO2 / brine) flow visualization under various reservoir conditions, and 4) development of Distributed Acoustic Sensing (DAS) technology using fiber-optic cable for monitoring CO2 behavior in the subsurface environment.
