Assessment and Forecasting of Additional Costs of Oil-Production Companies to Reduce Risks from Permafrost Degradation

— The article considers the methodology and results of the economic assessment of additional costs of the oil industry in the northern regions of Russia required for the construction of oil-production facilities under conditions of degradation of permafrost soils. On the basis of the analysis of three scenarios of oil extraction development, it is shown that depending on the situation the annual additional costs of the construction of oil-production facilities can vary from 53.4 bln rubles to 268.4 billion rubles. This makes up from 4.4 to 22% of the total value of investments in the extraction in the four largest oil-extracting regions of the country located in permafrost zone.
