Gas Hydrate RD Activities of Korea

摘要

From the 5 year preliminary study, BSR was found in the East Sea, Korea. 1~(st) phase of the national gas hydrate program has been conducted for three years from 2005. During this phase, 2-D and 3-D seismic surveys and sedimentary core sampling were carried out. After processing and interpretation of the acquired data, prospective area and drilling sites were selected. In 2007, KIGAM research team successfully sampled natural gas hydrate at the selected drilling sites using piston corer. Massive and disseminated gas hydrate samples were also found during the drilling of around 200 m depth.
