In terms of increasing the efficiency of development of hard-to-recover reserves of the Achimov deposits in Western Siberia, a generalization of the indicators of long-term operation of the facility at typical oil fields is of particular interest. At the oilfield under consideration, the low-permeability Achimov layer is currently the first object of operation in terms of current oil production and the second in terms of oil reserves. This horizon has a significant area, but the oil saturated thickness and density of recoverable reserves are small. The maximum oil production rate was achieved in 2019. Production rates of more than 2 % were recorded from 2010 to 2019. The current drilling capacity of the well design fund is 75 %. Less than a half of the initial recoverable reserves were developed with a water content of about 80 %. Several stages were identified in the formation of the development system for the Achimov layer over the history. The ratio of the number of producing wells to injection wells has decreased to 2,1, the current compensation is at the level of 100 %. In the last decade, the average flow rate of liquid at the facility has increased. The commissioning of horizontal wells, side shafts and hydraulic fracturing have an important role in increasing and stabilizing of oil production in Achimov layer. It is recommended to continue drilling production, injection wells and side shafts, to carry out primary and repeated hydraulic fracturing, to transfer wells to the Achimov horizon from other development sites.
