Russia's natural resources minister said on Friday that it was highly likely that U.S. oil major Exxon Mobil Corp "I have heard information about the possibility of such an event, the suspension of drilling, but I have not been officially informed of that ... The probability is high, it's most likely to have been stopped," Sergei Donskoi, the minister, told journalists. "Rosneft started to drill ahead of time ... it is still possible to carry out the drilling in the framework of the current licence."
