Emerging Europe this week Central Europe Romania-based Black Sea Oil and Gas will begin extracting natural gas from its 600 million US dollars offshore Romanian project in November, its chief executive Mark Beacom said on Tuesday, but added further progress hinged on scrapping a disputed tax. The additional tax on offshore projects is the last remnant of a series of price caps, taxes and export restrictions introduced two years ago by a previous centre-left government. The changes, most of which have since been reversed, blindsided gas producers, which have spent over a decade and billions of dollars preparing to tap Romania’s Black Sea gas.
