The task of forecasting the consequences of oil spill emergency in case of oil pipeline accident on the basis of GIS-technologies and calculation of economic damage caused to the natural environment (ENE) was set. Modeling of surface oil spill was carried out in Arc View GIS system using the adjusted Hydro Spatial Analyst module taking into account geofiltration of soils and terrain relief. The mathematical model of oil spreading is based on the equation describing the spread of a filtered liquid in porous material. The task of calculating financial and economic damage is based on the method approved by the Ministry of Fuel and Energy of the Russian Federation. A distinctive feature of the method used is that the fuzzy logic apparatus is used in the calculations. As a result of the work done, the consequences of the emergency situation can be presented on an electronic map, which makes it possible to calculate the area of contamination, the volumes of oiled pound and soaked oil, as well as the economic damage caused by the OPS.
