This work concerns studying the geologic structure of prospective interval and the thermal mode of section shallow part. Both the thermometry in wells with long idle time and measurements of temperatures obtained during testing the productive objects in the deep exploratory wells were used as the part of work for determining the section thermal mode. More than 7000 wells were used. The work resulted in the series of maps including ones on base permafrost characterizing the section shallow part, the thermal map at the depth 500 m, at the slices -1000 m and -1500 m. The derived data were used for determining temperature in the prospective reservoirs and mapping the regions with conditions favorable for gas hydrate deposit existence. The resource estimation is executed for five main prospective reservoirs: - Cenomanian deposits; - ipatovski reservoir joining ipatovskaya suite and gazsalinskaya unit of kuznetsovskaya suite which earlier considered as isolated; - russko-rechenskaya unit determined as the new prospective reservoir; - tanamski reservoir; - tibeysalinski reservoir. For each reservoir, the structure maps on their top and base and effective thickness maps were derived, the seal occurrence regions were contoured and resources were estimated.
