The article provides a comparative assessment of the digital maturity of the leading oil and gas companies of the Russian Federation admitted to work on the Arctic shelf (PJSC Gazprom Neft and PJSC Rosneft) in the exploration and production segment according to the stages of the «thing-digit-thing» cycle, as well as a comparison with leading practices in the field of project logistics on the shelf. It identifies approximate cost-cutting limits of digital transformation in Arctic projects and factors limiting cost efficiency of offshore projects in the Russian Arctic. The goal of the study is to identify a potential increase in digital maturity and scope of digital transformation in the Arctic project supply chain in Russia. The study is based on modern approaches to sustainable supply chain management in oil industry and supply chain streamlining for offshore projects. The article identifies a group of factors limiting cost efficiency of Arctic projects, specific to the Russian Arctic. It is established that the main factor limiting digital transformation of offshore projects in the Russian Arctic is the increasing technological underperformance of oil service companies. To build capacity in digital maturity of the offshore project supply chain, it is necessary to focus on disruptive technologies that could significantly lower the cost of oil production in the Arctic area.
