Lukoil said it had signed an agreement with US private equity group Carlyle over the sale of billions of dollars of overseas assets, which were hit when Washington imposed sanctions on the Russian oil company in October.
Neither Lukoil nor Carlyle disclosed the value of the prospective deal, which involves a sprawling portfolio, including oil and gasfields from Iraq to Mexico, thousands of petrol stations in 20 countries and refineries in Bulgaria and Romania.
The Russian oil group said its agreement with Carlyle was conditional, not exclusive, and it would continue negotiations with other parties, which include a partnership between US oil major Chevron and private equity firm Quantum Capital.
