“Our first quarter earnings were strong,” said Chairman and CEO John Watson. “Our consistent financial performance has enabled us to significantly increase the dividend again, and fund major development projects that are the foundation of the company's future growth in production, earnings and cash flows.”

“Our key development projects remain on track,” Watson added. “Construction is progressing well on the Gorgon and Wheatstone LNG projects in Australia. Important milestones have been reached recently for our Jack/St. Malo and Big Foot deepwater projects in the Gulf of Mexico, and both remain on schedule for start-up in 2014.”

• Australia - Reached agreement to acquire interests in two onshore natural gas blocks in the Cooper Basin.

• Australia - Announced a natural gas discovery, Elfin-1, in the Carnarvon Basin in 50 percent-owned Block WA-268-P.

• Republic of the Congo - Reached final investment decision on the deepwater Moho Nord joint development.

• United States - Announced a crude oil discovery at the Coronado prospect in the deepwater Gulf of Mexico.

• United States - Announced a successful production test of a St. Malo well in the deepwater Gulf of Mexico.

The company's Board of Directors approved an 11.1 percent increase in the quarterly dividend, to $1.00 per share, payable in June 2013. The company purchased $1.25 billion of its common stock in first quarter2013 under its share repurchase program.

UPSTREAM

Worldwide net oil-equivalent production was 2.65 million barrels per day in the first quarter2013, up from 2.63 million barrels per day in the 2012first quarter. Production increases from project ramp-ups in the United States and Nigeria were largely offset by normal field declines.

U.S. Upstream

	Three Months Ended March 31
Millions of Dollars	2013		2012
Earnings	$	1,132	$	1,529

U.S. upstream earnings of $1.13 billion in the first quarter2013 were down $397 million from a year earlier. The decrease was primarily due to lower crude oil realizations and higher operating expenses.

The company’s average sales price per barrel of crude oil and natural gas liquids was $94 in the first quarter2013, down from $102 a year ago. The average sales price of natural gas was $3.11 per thousand cubic feet, compared with $2.48 in last year’s first quarter.

Net oil-equivalent production of 664,000 barrels per day in the first quarter2013 increased 13,000 barrels per day, or 2 percent, from a year earlier. The increase in production was primarily due to further ramp-up of projects in the Gulf of Mexico, the Marcellus Shale in western Pennsylvania and the recently-

acquired Delaware Basin properties in New Mexico, partially offset by normal field declines. The net liquids component of oil-equivalent production was largely unchanged in the 2013first quarter at 455,000 barrels per day, while net natural gas production increased 7 percent to 1.26 billion cubic feet per day.

Millions of Dollars	2013		2012

*Includes foreign currency effects	$	172	$	(208	)

International upstream earnings of $4.8 billion increased $142 million from the first quarter2012. Lower crude oil production and realizations were partially offset by favorable tax items and lower exploration expenses. Foreign currency effects increased earnings by $172 million, compared with a decrease of $208 million a year earlier.

The average sales price for crude oil and natural gas liquids in the first quarter2013 was $102 per barrel, compared with $110 a year earlier. The average price of natural gas was $6.07 per thousand cubic feet, up from $5.88 in last year’s first quarter.

Net oil-equivalent production of 1.98 million barrels per day in the first quarter2013 was unchanged from a year ago. Production increases from project ramp-ups in Nigeria and improved operational efficiency at Tengizchevroil were largely offset by the continued shut-in of the Frade Field in Brazil, and normal field declines. The net liquids component of oil-equivalent production decreased 2 percent to 1.31 million barrels per day, while net natural gas production increased 5 percent to 4.05 billion cubic feet per day.

DOWNSTREAM

U.S. Downstream

	Three Months Ended March 31
Millions of Dollars	2013		2012
Earnings	$	135	$	459

U.S. downstream operations earned $135 million in the first quarter2013, compared with $459 million a year earlier. The decrease was due to higher operating expenses primarily as a result of turnaround activity at the refineries in El Segundo, California, and Pascagoula, Mississippi, as well as lower margins on refined product sales. The decrease was partly offset by higher earnings from the 50 percent-owned Chevron Phillips Chemical Company LLC.

Refinery crude oil input of 576,000 barrels per day in first quarter2013 was down 350,000 barrels per day from the year-ago period. The decline was primarily due to repairs of the crude unit at the refinery in Richmond, California, which has been offline since August 2012, and a planned crude unit turnaround at the refinery in Pascagoula. Refined product sales of 1.10 million barrels per day were down 141,000 barrels per day from first quarter2012, mainly reflecting lower gas oil, kerosene and gasoline sales. Branded gasoline sales decreased 1 percent to 500,000 barrels per day.

International Downstream

	Three Months Ended March 31
Millions of Dollars	2013		2012
Earnings*	$	566	$	345
*Includes foreign currency effects	$	76	$	(11	)

International downstream operations earned $566 million in the first quarter2013, compared with $345 million a year earlier. Earnings increased primarily due to higher margins on refined product sales. These benefits were partly offset by the absence of a 2012 gain on the sale of the company's fuels and finished lubricants businesses in Spain. Foreign currency effects increased earnings by $76 million, compared to a decrease of $11 million last year.

Refinery crude oil input of 818,000 barrels per day increased 39,000 barrels per day from first quarter2012, primarily due to consolidation of the 64 percent-owned Star Petroleum Refining Company in Thailand, beginning June 2012. Total refined product sales of 1.45 million barrels per day were down 73,000 barrels per day from first quarter 2012, mainly reflecting lower fuel oil and gasoline sales.

Net charges in the first quarter2013 were $439 million, compared with $504 million in the year-ago period. The change between periods was mainly due to lower corporate tax items and other corporate charges.
