Oil giant BP said it produced 4.025 million barrels of oil equivalent per day (boepd) of oil and gas in the first quarter of this year.
The world's second largest listed oil firm by market capitalisation said in a statement that excluding Russian operations, production rose as facilities hit by Gulf of Mexico Hurricanes last year came back on line.
The overall output result compares with production of 4.02 million boepd in the last quarter of 2005 and 4.10 million in the first quarter of 2005.
