Petroleum Intelligence Weekly Ranks World's Top 50 Oil Companies (2009)

Petroleum Intelligence Weekly's annual ranking of the world's 50 largest oil companies, a perennial benchmark survey recognized industry-wide, is the leading source of comparative performance assessments on all the world's oil companies. The Rankings are based on six operational criteria that allow the comparison of private sector and state-owned oil companies and is the precursor to the more comprehensive Energy Intelligence Top 100: Ranking The World's Oil Companies.

In contrast to national oil companies, the major oil companies and other private sector firms generally lost ground, especially in the top tiers. In contrast to other super majors, Exxon Mobil held on to its number three position. A comparison with results from 10 years ago shows that the top major oil companies, as a group, now account for a smaller global share of the six ranking criteria than they did prior to the mega-mergers that created them.

� Saudi Aramco remains No. 1, and China's CNPC surpasses BP and Shell.

� Three new firms moved into the PIW Top 50 -- Uzbekneftegas, China's CNOOC and Kazmunaigas of Kazakhstan -- all majority state-owned.

The PIW Top 50 can only give you a glimpse of the performance of the world's key energy companies. You can find out exactly how your company, client or competitor ranks against industry peers with the Energy Intelligence Top 100: Ranking the World's Oil Companies.

This annual special report from Energy Intelligence Research provides a detailed picture of how the leading energy companies -- both publicly traded and state-owned firms -- have performed. With coverage of more than 160 operational and performance criteria for the 130 largest oil companies in the world, it allows you to assess operating strengths and weaknesses, set goals based on peer performance and identify your best-in-class competitors.

Click here to preview the December 01, 2008 press release: Energy Intelligence Ranks World's 50 Top Oil Companies in Benchmark Survey

PIW's ranking of the world's 50 largest oil companies is based on operational data from over 130 firms. The focus on operations allows meaningful comparisons of all types of companies -- including state-owned firms -- and thus differs from more financially oriented corporate rankings. PIW's unique system uses as criteria oil reserves and production, natural gas reserves and output, refinery capacity, and product sales volumes.

Firms are compared in six different operational areas in the table below, with companies assigned a separate rank within each category. The six individual ranks are then added together to determine the cumulative, overall position, giving each of the six criteria an equal weighting.

The rankings above are based on the 2007 operational results for the companies as they existed at the end of that year or as they reported them. Estimates are used mainly for state-owned oil companies that do not release regular or complete annual reports in a timely fashion. Some numbers reflect estimates when complete corporate data are not available. PIW's system of ranking tends to favor national oil companies with large oil and gas reserves, and to favor integrated concerns over firms that specialize in one industry sector.

To round out the picture, basic financial data are provided for the companies. But these data are not used to create the PIW Top 50 rankings, since they are based on widely differing accounting practices.

Data in the tables above are primarily from company sources and annual reports. In some cases, secondary sources or PIW estimates have been used to fill in the gaps. Data are usually shown as reported by the companies but are sometimes adjusted for interests or shares held by others. Data for the Russian and Caspian firms are drawn from Energy Intelligence Research's 2008, Almanac of Russian & Caspian Petroleum.
