We considered various alternatives for tectonic zoning of the southwestern territories of The Republic of Sakha (Yakutia). Since 1975, the northern part of the Nepa-Botuoba anteclise has been considered the structure controlling the oil and gas bearing area of the same name. The Nepa-Botuoba oil and gas region is one of the unique territories of the ancient Siberian platform. Its hydrocarbon potential is only partially explored. Analysis of the evolution of ideas about the structure of the Nepa-Botuoba anteclise shows that as new data about its deep structure appear, the reserves of oil and gas increase almost synchronously. Currently, almost the entire resource base of the republic’s oil and gas industry is concentrated here.
