The San Ramon, Calif. oil company reported income of $4.55 billion, or $2.27 per share, for the first three months of the year. That compares with $1.84 billion, or 92 cents per share, in the same part of 2009.
Revenue increased 33 percent to $48.18 billion.
Analysts had expected earnings of $1.94 per share on revenue of $53.25 billion.
Like other oil majors, including Exxon Mobil, Chevron's results were boosted by a surge in profits from its exploration and production operation. The company's refining business, however, continued to struggle to pass higher crude costs along to customers.
