Energy Intelligence is delighted to share this year’s rankings of the world’s 50 largest oil companies by Petroleum Intelligence Weekly (PIW). The ranking sees Russia’s Gazprom moving ahead of international majors Chevron and Total to eighth place, while Rosneft climbed three places and is poised to enter the top 10 following its acquisition of TNK-BP earlier this year. Saudi Aramco remains in the top spot, followed by Iran's NIOC and Exxon Mobil.

This year’s rankings also demonstrate the impact of the US shale revolution for the first time, with a number of large US independents doing especially well due to their shale exposure. Chesapeake broke into the PIW Top 50 for the first time and Apache, Devon, Occidental and Anadarko all made solid gains, albeit from the bottom third of the list. These companies have all managed to improve their performance despite low natural gas prices, write-downs of gas reserves and sales of assets as they refocused investment on higher-value liquids plays.

By contrast to the dynamic performance of some key national oil companies and US independents, the international majors are not keeping up. While Chevron and Total declined in the rankings, Exxon Mobil, BP and Royal Dutch Shell stood still.

We have produced an infographic of the report, which highlights some of news stories from the ranking and we are delighted to share. Simply click here to view the infographic.

The PIW Top 50 ranking has an unrivaled pedigree, having been executed annually for the last 25 years. The ranking is based on six operational criteria and, unlike other corporate ranking systems in this industry, it allows for comparisons of both national oil companies and private sector firms. These Top 50 companies represent over 70% of global oil production and fully two-thirds of global refined product sales, making these rankings truly comprehensive and global. The rankings are based on 2012 data, the latest annual figures available.
