Marathon Oil in North America, including $600 million in the Eagle Ford and $200 million in the Bakken formation. The company owns 277,000 net acres in the Bakken formation. Marathon began as The Ohio Oil Company in 1887. In 1889, it was purchased by John D. Rockefeller's Standard Oil. It remained a part of Standard Oil until Standard Oil was broken in 1911. In 1930, The Ohio Oil Company bought the Transcontinental Oil Company and established the "Marathon" brand name. In 1962, the company changed its name to "Marathon Oil Company". In 1982, Mobil made a hostile offer to buy the company;
Standard Oil company to hold shares in other companies in any state. So, in 1899, the Standard Oil Trust, based at 26 Broadway in New York, was legally reborn as a holding company, the "Standard Oil Co. of New Jersey" (SOCNJ), which held stock in 41 other companies, which controlled other companies, which in turn controlled yet other companies. According to Daniel Yergin in his Pulitzer Prize-winning "" (1990), this conglomerate was seen by the public as all-pervasive, controlled by a select group of directors, and completely unaccountable. In 1904, Standard controlled 91 percent of production and 85 percent of final sales.
