Iraq awarded a lucrative oil contract to BP and China National Petroleum Corp., government spokesman Ali al-Dabbagh said Wednesday, while rejecting other companies’ offers for other oil fields. The joint BP-CNPC bid was for the al-Rumeila oil field, one of the largest in the world. The energy companies are expected to increase production at the oil field by 50 percent, to 285,000 barrels a day, for a service charge of $2 for each additional barrel produced, al-Dabbagh said in a statement
