Which company is the world's largest publicly traded oil producer by output?

Saudi Aramco is the world’s largest publicly traded oil producer by output.

Saudi Aramco is the short name for Saudi Arabian Oil Company, the national oil company of Saudi Arabia. It operates major oil and gas fields, refineries, pipelines, export terminals, and petrochemical interests, making it one of the most important energy companies in the global economy.

The company traces its origins to an oil concession granted to Standard Oil of California in 1933. Oil production began in commercial quantities at Dammam Well No. 7 in 1938. Saudi Arabia gradually increased its ownership, and the company became fully state-owned in 1988.

Saudi Aramco listed a portion of its shares on the Saudi Stock Exchange in 2019. “Publicly traded” does not mean it is privately controlled: the Saudi government remains its dominant shareholder.
