In the work, the properties and behavior of oil spills accidents at oil pipelines are investigated. The analysis of the main stages of an land oil spill was carried out, the total amount of oil spilled from the pipeline and the factors affecting the initial volumes of oil spills were estimated. Existing methods for modeling the spread of oil spills are considered taking into account the topography; a combined algorithm for calculating the oil pollution configuration was developed, followed by software implementation as Python script and displaying the results on thematic maps in ArcGIS for Desktop. The questions of the influence of the phenomena of evaporation and oil filtration on the spill configuration are investigated and the adequacy of the model is evaluated. Possible modeling oil spills at the oil pipelines of the Republic of Bashkortostan were selected as an example of modeling, since the Republic of Bashkortostan is one of the most significant oil producing regions of Russia. The results of the algorithm and the implemented program can be used to identify the most dangerous sections of the pipeline, determine the most likely directions for the spread of emergency spills in emergency situations in order to prevent them and optimize the work on eliminating the consequences.
