The article is dedicated to the fortieth anniversary of Priobskoye oil field discovery, one of the most unique fields in the Russian Federation. The Priobskoye field belongs to the category of unique not only in terms of reserves, but also in terms of its most interesting development history. 40 years ago, the field was discovered based on the results of testing the exploration well No. 151P, which proved the presence of commercial hydrocarbon reserves. Despite this, this field could not be approached for a very long time due to the inaccessibility of the area, where it was necessary to build infrastructure from scratch, lay roads, pipeline networks and much more, and also, taking into account the fact that most of the reserves belong to the category difficult to recover, the reservoirs are characterized by a very complex geological structure and are characterized by low permeability values. Today it is a whole industrial area with several production and preparation shops, bases of process management and contracting organizations, the largest industrial infrastructure has been created. The development of this field has come a long way, on which, with the acquisition of new knowledge and the development of technologies, the fundamental design solutions and approaches to its development have repeatedly changed. Today, the Priobskoye field is one of the most key fields in our country and Rosneft, providing 13% of its annual Company’s oil production. And besides all this, it is an advanced testing ground and implementation of technologies for the development of ultra-low-permeability reservoirs, the positive results of the pilot work are broadcast to similar areas of the Rosneft Oil Company's fields. The authors provide a brief history and description of the main stages of development, an overview of the reasons that led to fundamental changes and the evolution of project decisions.
