LUKOIL ranked 5^th among the oil and gas companies of Europe, Middle East and Africa, and placed 10^th among the world’s majors in the 2011 list of ‘Top 250 Energy Companies’ compiled by the American energy agency Platts.
All companies were ranked by four main criteria: asset value, revenues, profits and return on invested capital.
The valuation was performed based on Standard & Poor’s database which is, like Platts, a unit of The McGraw-Hill Companies.
