摘要

描述Reservespie.png	English: The distribution of oil and gas reserves among the world's 50 largest oil companies. Total reserves in Oil Equivalent Barrel (OEB) here means liquid oil + natural gas. Made using figures reported in "OGJ 200/100", Oil & Gas Journal, September 15, 2008. Please note that this chart assumes that Petrochina, Gazprom, and OAO Rosneft are state-owned companies. According to Wiki, they are: Petrochina: "the listed arm of state-owned China National Petroleum Corporation." Gazprom: "privatized in part, but currently the Russian government holds a controlling stake." Rosneft: a joint stock company "owned by the Russian Government". I would appreciate it if someone could confirm the above, I will update the graph. Türkçe: Petrol ve doğal gaz rezervlerinin, Dünya'nın en büyük 50 petrol şirketi arasındaki dağılımını gösteren grafik.
