Recently, Amy Myers Jaffe of Rice University’s Baker Institute spoke to the Women’s Energy Network of Houston on the topic of "The Changing Role of National Oil Companies in International Energy Markets." One interesting fact she presented is that, based on the amount of oil and gas reserve holdings, 14 of the top 20 upstream oil and gas companies in the world are national oil companies or newly privatized national oil companies. The focus of her speech was to share some of the results of case studies that the Baker Institute has done on several of these national oil companies to explore their company cultures, priorities, etc. To learn more about this project and to view the actual case studies, see the attached link.
