Abstract

Lake Baikal is the only fresh-water lake where natural gas hydrate accumulations were found in sediments. For the recent decade, Baikal has become a natural laboratory for investigation of the properties of gas hydrates, their indicators, and recovery of gas from subsurface (subbottom) gas hydrates. We present the main results of subsurface gas hydrate mapping and gas recovery test near the delta of the Goloustnaya River.
