Investigation finds Western equipment still flowing to Rosneft’s Vostok Oil project — and Putin’s unofficial father-in-law is benefitting
Western oilfield service firms' subsidiaries in Russia continued supplying equipment and services to Rosneft's Vostok Oil project, despite parent companies' withdrawals. The investigation found payments to entities linked to Baker Hughes, Halliburton, Weatherford, and SLB. Vostok Oil, under U.S. sanctions, received significant investments and faced environmental concerns. Marat Kabaev, linked to Putin, acquired a stake in a major contractor.
