Hill Cos. Global oil demand is roughly 82 million barrels a day, or about 4 percent higher than a year ago, according to PFC Energy, a Washington-based consulting group. Last week, concern about Russian supplies was the dominant factor in oil markets. The Russian government is in a battle with oil giant Yukos over billions of dollars in back taxes, and company officials have said its production of 1.7 million barrels per day could suffer. On Monday, the embattled oil company Yukos suffered a double blow Monday as bailiffs renewed their seizure of assets of its key production unit and a court rejected the company's appeal against the seizure of another subsidiary. --More 2259 Local Time 1959 GMT
