Due to efficient geologic surveys, the modern data processing system, and the use of new technologies, it was possible to increase the field’s reserves. The improvement of reserve replacement efficiency is one of the key elements of the Rosneft-2022 Strategy. The company has undertaken a commitment to replenish at least 100% of the hydrocarbons produced.
During the operation of the Verkhnechonskoye field from 2013 to 2019, the company’s specialists accumulated a significant amount of geological and geophysical information through the study of production wells. Based on the results of the new stage of exploratory drilling and production drilling with core sampling collection, the geological model of the field structure, including its petrophysical model, was updated.
In November 2019, together with Rosneft’s design institutes, Tyumen Oil Research Centre and RN-KrasnoyarskNIPIneft, they carried out work to calculate reserves and supplement the field production model.
Changes in the number of reserves will help to update the development system of the Verkhnechonskoye field, which in turn will extend its life cycle.
The Verkhnechonskoye field is developed by Verkhnechonskneftegaz, a subsidiary of Rosneft. Its equipped with all the necessary infrastructure for the production and treatment of oil for the market.
