Russian oil companies rely on foreign technology, and sanctions affect 68% of imported equipment. In order to extract difficult-to-access oil, Russian companies need to buy 50% of required equipment and 80% of the software used in the devices from the West; in the case of sub-seabed deposits, 80% of equipment and 90% of software must be imported. Western sanctions on technology connected to oil production have forced Rosneft to postpone all planned exploration of deposits in the Arctic and offshore fields. Restrictions on importing technology also apply to spare parts that are not produced in Russia. For example, 90% of the spare parts used at Gazprom Neft’s drilling platform in the Prirazlomnoye field are foreign.
