Chevron Corporation: CEO History

In 1933, Standard Oil of California — Chevron's predecessor — traded a few thousand gold sovereigns for exclusive exploration rights over 360,000 square miles of Saudi Arabia. The deal looked speculative at the time. Five years later, they found oil. What followed became Saudi Aramco, arguably the most profitable single corporate asset in history. Chevron's 145-year arc began with one bet that paid off at a scale almost no one predicted. Today Chevron produces approximately 3.1 million barrels of oil-equivalent per day across operations in more than 180 countries. Its El Segundo refinery on the California coast processes 269,000 barrels per day — the largest refinery on the West Coast. The company's 40,000 employees operate everything from deepwater platforms to pipeline systems to retail fuel stations, though under CEO Mike Wirth, Chevron has shed retail assets and concentrated on upstream production and downstream refining. The Tengizchevroil joint venture in Kazakhstan tells the story of Chevron's willingness to operate in politically complex environments at extraordinary scale. Chevron holds a 50 percent stake in one of the world's largest oil fields. The FGP-WPMP expansion that came online in 2024 added approximately 260,000 barrels per day of incremental production capacity — a single project equivalent to the total output of a mid-sized OPEC member. Headquartered in San Ramon, California — a state that bans new oil drilling — Chevron produces more petroleum than most OPEC nations. That contradiction is not accidental. California's restrictive regulatory environment makes the state an expensive place to produce oil, which means Chevron's California operations survive only because of decades of sunk infrastructure. The company's real growth happens elsewhere.
