Relevance. The paper discusses the digital ontology-driven approach to the development of a quasi-integrated supersystem. The supersystem includes the energy sector and its supporting elements of the financial and economic system of Russia and a group of friendly countries who are consumers of Russian fuel and energy resources (FER). The approach is employed to develop measures that ensure national and international economic and energy security. International deliveries of Russian fuel and energy resources to the segments of the world economy available for exports can become unstable due to the current crisis in international economic relations. The use of the digital ontology-driven approach is a response to the need to analyze the underlying processes and predict whether such instability can become critical in the future. This is done in conjunction with configuring properly the operation of the Russian infrastructure of production, transport, storage, processing, and deliveries of fuel and energy resources. To that end, they are to be adjusted so as to align with the transformation that the destinations and structure of Russian exports are undergoing. Problem statement. We argue for the adoption of the digital ontology-driven approach to the development of a quasi-integrated supersystem. The supersystem includes the energy sector and its supporting elements of the financial and economic system of Russia and a group of friendly countries who are consumers of Russian fuel and energy resources being parties to economic unions and bilateral agreements between the countries. We identify different variants of the impact of effected discriminatory practices and the state of commodity and financial markets. We study this impact as applied to 1) Russian energy companies supplying FERs abroad, 2) consumers of Russian FERs in Russia and abroad, 3) companies transporting FERs abroad and using other countries for transit through them, and 4) manufacturers of equipment for the energy sector. Purpose of the study. We aim to identify conceptual approaches clarifying the effect of macroeconomic factors on 1) Russian energy companies
