Energy Intelligence today releases its annual ranking of the world's 100 largest oil and gas companies, the only ranking system that compares private sector firms with national oil companies. The Energy IntelligenceTop 100 is an in-depth company analysis that ranks six key operational metrics together with 70 additional parameters of company performance.

Here are some of the key findings from the 2014 ranking:

  • National Oil Companies (NOCs) outnumber International Oil Companies (IOCs) in the Top 10 for the first time in 13 years
  • Saudi Aramco tightened its already firm hold on the number one spot for the 26th consecutive year
  • China's CNPC climbs to No. 3, knocking ExxonMobil from the spot it has held for the past seven years
  • Rosneft has surged into the Top 10 through its acquisition of TNK-BP, tying with Gazprom, cementing Russian NOC prominence, moving Chevron down and pushing Total out of the Top 10
  • Regionally, companies in both North and South America saw strong gains in the rankings
  • The US Marcellus Shale is a key factor improving the rankings of independent oil companies

“Size matters. The Top 10 companies in the Energy Intelligence Top 100 universe represent a significant share of the world’s petroleum operations, including close to 40% of the world oil production and roughly half of its oil reserves”, says David Kirsch, Managing Director of Energy Intelligence's Research & Advisory arm. "Our experienced analysts focus on operational metrics that capture how oil and gas companies actually perform. By placing all national oil companies and their international oil company rivals on an even basis, our goal is to provide a Top 100 ranking that sets credible industry benchmarks.”

Energy Intelligence’s flagship publication Petroleum Intelligence Weekly is also publishing the rankings of the Top 50 oil companies along with valuable insights into their performance. PIW’s Top 50 has appeared for the past 26 years and provides the ranking methodology for the much larger Energy Intelligence Top 100.

Six parameters are used to compile the rankings: oil reserves, natural gas reserves, oil production, natural gas production, refinery distillation capacity and refined product sales. The Energy Intelligence Top 100 analysis considers an additional 70 financial and operational parameters.

The Top 10 companies in this year’s rankings are:

  1. Saudi Aramco
  2. NIOC
  3. CNPC
  4. Exxon Mobil
  5. PDVSA
  6. Shell
  7. BP
  8. Gazprom
  9. Rosneft
  10. Chevron

The list of the Top 50 companies can be viewed at and the full Top 100 company analysis is available to Energy Intelligence clients as part of its suite of online interactive tool services.
