(Reuters) - Exxon Mobil Corp
Exxon and other large oil companies struggling to boost production in recent years have spent heavily on new projects. In the first nine months of this year, Exxon alone spent $33 billion.
"This is their first year-over-year (production) increase in more than two years," said Brian Youngberg, an energy company analyst at Edward Jones in St. Louis. "It does show that they are hopefully making some progress stemming the decline that they've shown the last couple of years."
Exxon last reported a quarterly gain in production in the second quarter of 2011.
Third-quarter oil and natural gas output rose 1.5 percent from a year earlier to 4 million barrels oil equivalent per day, helped by the start-up of new projects, the Irving, Texas, company said.
Natural gas from Australia's Kipper Tuna Turrum project and accelerated output from projects in Nigeria and Canada also contributed to the higher production.
Profit in the third quarter was $7.87 billion, or $1.79 per share, compared with $9.57 billion, or $2.09 per share, a year earlier.
Analysts on average had expected $1.77 per share, according to Thomson Reuters I/B/E/S.
"Weaker margins, mainly in refining, decreased earnings by $2.4 billion," Exxon said in a statement.
Oil companies with refining units, such as Exxon and Royal Dutch Shell
Exxon's refining unit had a profit of $592 million in the latest quarter, down sharply from $3.2 billion a year earlier.
The company's shares rose 1 percent to $89.68 in morning New York Stock Exchange trading.
