Effective system for hard-to-recover reserves development of the BS92-2ach reservoir of the Achimov formation of the Sorovskoye field

Abstract

At the moment, hard-to-recover reserves start playing bigger role in oil production all over the world. In Russia, they account for more than 65% of the total proved reserves. Therefore, the effective development of hard-to-recover reserves is one of the most important and promising tasks of oil producing enterprises. The Achimov formation in Western Siberia has large oil production potential, but traditional approaches are not efficient enough to develop such complex reservoirs. The purpose of the work is the development analysis and the best option selection for the development of oil deposits of hard-to-recover reserves. The article considers various ways to solve the problem. The most promising are the two options – the drilling of multilateral wells and the drilling of horizontal wells with low-volume hydraulic fracturing. As a result of the analysis of the geological structure and calculation on the hydrodynamic model, it is concluded that the most optimal way is to drill multilateral wells. Economic calculations confirm the feasibility and profitability of the project.
