China Petroleum & Chemical Corp. (386) , Asia’s biggest refiner known as Sinopec, agreed to pay about $1.2 billion to buy a 50 percent stake in energy assets in Kazakhstan from Russia’s OAO Lukoil. The deal is expected to be completed before the end of the year, Lukoil said in a statement. Lukoil’s Caspian Investment Resources Ltd. owns, through a number of joint ventures, various stakes in four hydrocarbon-production projects in Kazakhstan. Lukoil’s share in commercial hydrocarbon production as part of the projects was 10.2 million barrels of oil equivalent in 2013, it said.
