Largest American oil and gas companies

The oil and gas industry is one of the largest industries worldwide. This sector is involved in exploration, extraction, refining, transport, and marketing of these commodities. Many industries are extremely dependent on oil and gas products, mostly in the form of energy fuels or raw materials for chemical products.

Oil and gas companies from the United States are among the world’s largest corporations. For example, ExxonMobil, Conoco Phillips, and Chevron have all long been global leaders based on revenue. Periodically, ExxonMobil has been the world’s largest company in general, with revenues exceeding the mark of 400 billion U.S. dollars in several recent years. As of June 2019, it was also the company with the tenth highest market capitalization. Most of the top U.S. oil and gas companies have operations all over the world, generating large portions of their incomes outside of the United States.

The United States has a long tradition of oil and gas companies. ExxonMobil, for example, is a direct descendent of Rockefeller’s Standard Oil Company, which was founded in 1870. Chevron has its roots in the Pacific Coast Oil Company, which was founded in 1879.
