Features of the development of hard to recovery reserves of the Achimovskaya site of the “N” deposit

Background. The development of objects that are complex from a geological point of view is characterized by the low efficiency of traditional methods of enhanced oil recovery, the absence or high cost of technological support for production by alternative methods. In this paper, the development features will be considered using the example of an existing object related to the Achimov strata of Western Siberia.Aim. A retrospective analysis of the dynamics of the development of a production facility, additional study of the possible causes of high water cut.Materials and methods. To write the work, design documents were used containing data on the geological and physical characteristics and dynamics of production at the production site, as well as graphic applications (geological sections, well logs, extracts from maps). The study of materials, graphic applications and graphing in Excel was carried out.Results. The possible reasons for the high water cut in the production were studied.Conclusion. The vector of further development of research activities within the framework of a given topic is determined.
