| Summary: | Prirazlomnoye oil field is the only field on the Arctic shelf of Russia, where oil production has already begun. Oil production at this field is complicated by both weather and marine production conditions. Oil production at this field is carried out using horizontal wells with multi-stage hydraulic fracturing. In such type of wells, there is a problem of the correct fluid flow profile determination in the well. For this purpose, tracer (indicator) studies are carried out. The relevance of the work is due to the growth of oil production in offshore fields every year. Technologies for oil and gas production do not stand still and are being improved in various directions. For example, tracer technologies are a modern method of studying the whole reservoir of the field and the wells separately. At present, there is an urgent need to quickly obtain information that helps to extract hydrocarbons safely and most effectively from the earth's interior. The Master Thesis describes the Pechora Sea environmental conditions. The method of tracer studies at the Prirazlomnoye oil field is described. The analysis of the results obtained after selecting and examining samples by the laboratory method was carried out. The operating intervals of wells and the flow rate of each interval are determined. Finally, recommendations for further tracer studies of the well are given.
