Geological-economic ranking of gas perspective territories of Eastern Siberia
Compensation of raw material base of Russian gas industry is impossible without resources development of Easter Siberia perspective regions (within the limits of ancient Siberian platform). Initial total gas resources of these regions account to 50,0 trillion standard units. The share of proved reserves (ABCi categories) reaches six percent (6 %) of this estimation, varying from 13,6 percent in Irkutsk region to 1,7 percent in Krasnoyarsk district. It provides possibility of discovering new comparatively big gas accumulations in addition to Kovyktinsky, Chayandinsky and other unique gas fields already found. Contemporary economic conditions demand spatial-temporal clustering of perspective territories and objects to develop these resources in order to reveal the most favorable ones for investing and to determine priority of their development. It will allow providing maximum efficiency of investment program realization. The above-said stimulated carrying-out complex geological-economic modeling of various-scale objects. The modeling included their ranking with the view of their attractiveness for potential investors (regarding various hierarchy and information-assured levels, such as oil and gas bearing areas, fields, prepared and discovered structures, localized resources, etc.). The carried-out researches allow formation of portfolio of geological-investment projects and differentiate it in accordance with economic efficiency degree. They provide possibility of formation of complex business-projects portfolio full of original visual-informational documentation. The suggested results of complex geological-economic research work, carried out to discover gas perspective territories of Eastern Siberia, allow risk decrease connected with implementation of investment programs on resource supply of Eastern export hydrocarbon corridor, "Eastern Siberia-the Pacific" pipeline system being the basic part of which, including prospecting programs.
