KIEV, June 13 - Ukraine's government has concluded negotiations with U.S. energy major Chevron on a second shale gas project and is lining up another energy deal with an ExxonMobil-led consortium.

Chevron has been in talks with Kiev for several months over exploration in the 5,260sq km Olesska field in western Ukraine, with the government keen for shale gas to ease Ukraine's dependence on costly natural gas supplies from Russia.
