ExxonMobil is the world's largest publicly traded international oil and gas company. It holds an industry-leading inventory of global oil and gas resources. ExxonMobil is the world's largest refiner and marketer of petroleum products, and its chemical company ranks among the world's largest.

ExxonMobil was formed through the merging of Exxon and Mobil, which were formerly known as Standard Oil of New Jersey and Standard Oil of New York, respectively. Both of these companies were descendants of the Standard Oil Company, which was dissembled in 1911 due to its monopolistic nature.
