We propose and test a method for probabilistic estimation of the scale and structure (distribution of helium concentrations in free gas, accumulations of different sizes, localization zones, and stratigraphic complexes) of helium and helium-containing gas resources. Summarizing the available geological information about the structure of the sedimentary cover and data on the revealed accumulations of helium-containing gases, we have first made probabilistic estimation of the scale and structure of their resources as well as helium resources in the central and southern areas of the Lena-Tunguska province. The forecast results will serve as a reliable basis for geological and economic estimation of helium resources, for long-term planning of gas field development in East Siberia and the Republic of Sakha, and for helium industrialization in these regions.
