Abstract

The relevance. Crucial task for the Khanty-Mansiysk Autonomous District (Yugra), the main hydrocarbon crude and petroleum production base of Russia, is prevention of decline and stabilization of petroleum recovery. This can be arranged by vigorous integration of hard-to-extract reserves in exploration. The aim of the research is to determine sources, directions and priorities of increasing oil resource base and stabilization of oil production in Yugra, with focus on potential of hard-to-extract reserves. Object: resources from allocated and unallocated subsoil reserve funds, volumetric oil production of main petroleum companies and major fields, hydrocarbon plays. Research methods: look back analysis and prognosis of oil reserves and oil production dynamics, oil geological and mining classification of hard-to-extract reserves. Results. The authors have analyzed the data of the Department for Subsoil Use of the Khanty-Mansiysk Autonomous District (Yugra) and «Research and analytical center for rational use of the subsoil named after V.I. Shpilman». 98,9 % volumetric oil production in Yugra belongs to nine integrated oil companies, 51,7 % of volumetric oil production accounts for 14 large/scale deposits. The situation of petroleum recovery in Yugra since 1964 is analyzed, with detail starting from 2008, when predicted decline in oil production for the period up to 2030 was prepared. The prediction was fully confirmed in 2018. The paper introduces the logical causes of decline in petroleum recovery with the forecast of production decline to 220 million tons by 2020. One of the reasons is the objects discovered and introduced in exploration over the last years, which are generally the hard-to-extract reserves. Based on mining and geological factors seven groups of deposits with hard-to-extract reserves were identified, and real oil reservoir differentiation of Yugra was given. It is shown that one of the real source, providing stabilization of oil extraction, is vigorous integration of hard-to-extract reserves in exploration of Achimov and Tyumen plays, where the volumetric oil production have increased in 5-10 times since 2000. Growth of hard-to-extract reserves production of pre-Jurassic play is possible. Its cumulative production is 32 million tons. Resources of Bazhenov-Abalak play, which will be involved in exploration until 2030, can compensate for falling oil production in Yugra.
