According to revenues and market value, the Exxon Mobil Corporation is one of the largest companies worldwide
today - and has been for the past years. Different sources may vary, but ExxonMobil has been ranked first or second on almost all company top lists
. The oil and gas company is headquartered in Irving, Texas. It was formed in 1999 through the merger of Exxon and Mobil, but its roots go back to John D. Rockefeller’s Standard Oil Company.
2011 was ExxonMobil’s most successful year in terms of revenue
, exceeding the previous year by almost 100 billion U.S. dollars. The same can be said for the company’s profits, which amounted to more than 41 billion U.S. dollars in 2011. At the end of 2011, ExxonMobil had a market valuation of more than 400 billion U.S. dollars. Approximately 82,100 persons were employed by ExxonMobil
ExxonMobil is composed of three divisions: Upstream, Downstream, and Chemical. Upstream
, which includes exploration and extraction, is by far the most important division. With approximately 34.5 billion U.S. dollars, it was responsible for around 84 percent of the company’s total net income in 2011. In the same year, ExxonMobil Upstream’s production output
in oil equivalents was some 4.5 million barrels per day.
The company owns 36 oil refineries worldwide, with a refining capacity of some 6.2 million barrels per day. That makes ExxonMobil the world’s largest refiner. The company’s total proved reserves
reach a total oil equivalent of 24.9 billion barrels. However, Exxon Mobil owns less than one percent of the world’s total oil and gas reserves.
