Italian energy major Eni is proceeding cautiously with its joint venture with Rosneft in the Black Sea, an activity that has attracted scrutiny due to western sanctions on Russia. On Wednesday, Eni's chairwoman, Emma Marcegaglia, told a panel at Davos that her firm had suspended its offshore drilling with Rosneft due to U.S. sanctions. Hours later, she reversed her statement, telling Reuters through a spokesman that "the exploration well in the Black Sea is being drilled as planned."
