10 Biggest Oil Companies

SNP, PTR, and TADAWUL: 2222 top the list of the 10 biggest oil companies

Oil remains a dominant source of energy worldwide, Oil companies supply billions of barrels of petroleum products daily to power transportation and industry. Rising public concern about climate change and measures to reduce the use of carbon-based fuels have had a very limited effect to this point. After a punishing slump in crude prices in the early stages of the COVID-19 pandemic, many of the world's leading oil companies were gushing cash again by 2021 as a global economic recovery took hold.

Below we look at the 10 biggest oil companies (refiners as well as crude producers) by 12-month trailing (TTM) revenue. While U.S.-based companies make up half of the list, the ranking also includes companies based in Saudi Arabia, China, the U.K., and France.
