In this work, the Monte Carlo method is used to determine the effectiveness of investments of Russian projects of the export of liquefied natural gas to the countries of the Asia-Pacific region, namely Japan, China and South Korea. The volumes of capital costs for the construction of the facility, operating costs for the operation of the facility, the price of liquefied natural gas were chosen as free parameters in the application of the Monte Carlo method. To perform the work, a forecast of prices for liquefied natural gas in the Asia-Pacific region was made based on the forecast of prices for Brent crude oil. Furthermore, the paper presents a forecast of operating costs for the operation of the project until 2035. The result is to determine the economic efficiency of the Yamal LNG project. The application of the Monte Carlo method showed that the net present value of the project by 2035 is most likely to be about $ 22 billion. Such an excellent result was possible due to the significant tax benefits provided by the state in accordance with the program of development of the oil and gas industry in the Arctic part of Russia.

At present, Russia's oil production in a number of large Eastern Siberia fields (Verkhnechonskoye, Talakanskoye, Yaraktinskoye) has reached or approached its maximum designed levels, therefore, the fields have progressed to the second stage of development or to the beginning of the third stage experiencing production declines. Thus, these fields can be categorized as brownfields. At the Verkhnechonskoye oil and gas condensate field, for the first time in the history of domestic oil and gas production the geologists came across a highly mineralized productive cross-section with the pore space partially or completely filled with salt. This determined the distinctive development features of the main target - the Verkhnechonsky horizon (Vch) (99.8% of the field's production). A distinctive feature of this paper is the description of the approaches to the development of the Verkhnechonsky horizon associated scaling formation and control using a wide range of geological and geophysical tools. The value of the work lies in the summary of lessons learned when managing reserves production and well operation processes at a large Eastern Siberia field, the development of which is complicated by the presence of salts in the pore space, which was the starting point of accumulating the knowledge on salt reservoir development. The experience based on a range of approaches and technical solutions can be applied to similar Eastern Siberia reservoirs with similar geological and physical characteristics.
