Nowadays, active human economic activity leads to significant man-made pollution. In a number of cases geological environment is polluted with hydrocarbons by an accident. That leads to change in physical and mechanical properties of grounds and has negative impact on entire an ecosystem. This work is devoted to identification of regularities and c...

The work provides an assessment of the geoecological situation during an oil spill on the water surface. The modeling of the process of oil burning on the water surface is carried out, and also a model for estimating the oil burning time during depressurization of the underwater passage of the main oil pipeline is proposed. The assessment of indivi...

Objective: to study the ecological and economic prospects of Russian Arctic oil and gas offshore projects by the method of functional analysis.
Methods : mathematical modeling, comparative analysis, empirical analysis.
Results : a method is proposed for assessing the financial provision of measures to eliminate the alleged environmental damage caused by hydrocarbon spills in Arctic offshore oil and gas production projects; models of oil spills in the “Prirazlomnoye” and “Pobeda” Arctic offshore fields are considered; the cost of measures to eliminate these incidents is estimated.
Scientific novelty : for the first time, the paper investigates the function of financial provision for measures to eliminate the alleged environmental damage due to hydrocarbons spills at the “Prirazlomnoye” and “Pobeda” Arctic offshore oil and gas fields with the mathematical method of functional analysis, calculation of the maximum costs, as well as the time from the start of the spill, which accounts for these functional values. The assumption of the mathematical model is the hypothesis of the constancy of the well flow rate (the top estimate is the characteristic flow rate of the per second production of the entire field), as well as the neglect of changes in the physical properties of liquid hydrocarbons (viscosity, density) due to the characteristic annual temperature dynamics of the Arctic regions and consideration of the dynamics of the oil spill spread on the sea surface in the inert phase without taking into account the gravitationally viscous and surface modes.
Practical significance : the mathematical modeling data on spills can be used by insurance companies in the calculation of insurance premiums, by Rosprirodnadzor Agency in the calculation of fines, and by other supervisory agencies in the underwriting of oil and gas Arctic projects.
