) to legally tie their hands together, facilitate cooperation, and prevent cheating on one another). The companies sought to limit the supply of oil by controlling the speed at which oil fields were developed. From the 1920s to 1940s, they had agreements not to produce oil in the Middle East unless it was in coordination with one another. After the 1940s, the companies continued to collude. The discovery of massive oil fields in Saudi Arabia threatened to scuttle the cartel, as control of the oil fields by two companies could undermine existing supply management schemes. However, control of the Saudi oil production ultimately became jointly controlled by four of the seven sisters, thus making it easier to maintain coordination between the Seven Sisters. According to Jeff Colgan, the Seven Sisters faced two major problems. The first revolved around coordinating the activities of the companies so that oil prices would be kept high. The second revolved around cooperation with the governments of the territories containing the oil reserves: the companies sought to minimize the taxes and royalties paid to the governments. In terms of dealing with host governments, the Seven Sisters benefitted from the willingness of British and American governments to pressure and coerce the host governments. The oil companies also slowed down production when taxes and royalties were increased by one host government while ramping up production in other territories with lower taxes and royalties, thus pressuring host governments to keep taxes and royalties low. Host governments faced a number of hurdles in terms of nationalizing the oil production. First, a number of oil-producing countries did not have independence and were controlled by empires. Second, great powers had installed compliant heads of state in several oil-producing countries, making those leaders reliant on the support of the great powers and unwilling to upset them. Third, a number of oil-producing countries lacked the capital and technical expertise to run the oil production, as well as needed access to North American and European markets. Fourth, oil-producing countries feared that they would be punished by Western governments and firms if they nationalized oil production (as

, by 2012 only 7% of the world's known oil reserves were in countries that allowed private international companies free rein. Fully 65% were in the hands of state-owned companies. The Era of the Super-Major The Era of the Super Major was an industry report published by Douglas Terreson of Morgan Stanley on February 13, 1998. Mr. Terreson was the top rated Integrated Oil analyst according to Institutional Investor magazine at the time and had a broad following within the global investment community. After many years of poor industry performance by the Energy sector. Mr. Terreson suggested that business models had become obsolete and that major strategic change was needed across the global Energy sector for value propositions to become competitive with the other parts of the market. The premise of the report was that "a confluence of industry dynamics would conspire to produce a strategic and financial environment that was conducive to major consolidation activity in the Integrated Oil sector. Significant modifications to the strategic landscape would result, dictating competitive placement and equity market performance for years to come". The report indicated that the phase would be driven by the competitive implications of: (1) the globalization of privatized national oil companies and (2) the rising stature of specialized multinationals. Combinations were expected primarily between Major Oils which would then become "Super-Majors" which was a phrase created at Morgan Stanley in the late 1990's to denote the prototype model for success in the Integrated Oil industry as gains in globalization and scale unfolded. Within 6 months of publication of "The Era of the Super-Major", BP and Amoco merged, representing the largest industrial combination on Wall Street at that time. The combined value of the stocks of those 2 companies rose significantly and that merger was followed by Exxon-Mobil, BP-Amoco-Arco, Conoco-Phillips, Chevron-Texaco-Unocal, Total, Elf Aquitaine and others. The phase represented one of the largest consolidation phases in the history of the Energy sector. Corporate performance was very positive in Energy thru 2007, underscoring the premise that the "Super-Major" thesis would create significant economic value for shareholders. * Exxon and Mobil merging to form
