Thousands of miles away, far greater potential hazards afflict the Caspian Sea, which should be experiencing a record breaking oil boom. Russia is stepping up its naval patrols amid bitter feuding between five nations over the carve-up of the world's third largest oil and gas reserves. Iran has already sent out gunboats in a row with Azerbaijan, disrupting BP's work in the Alov-Sharg-Araz field. The result is a loss of confidence in the Caspian, said Julian Lee, senior analyst with the London-based Centre for Global Energy Studies. 'If you are sitting in Houston or London and you hear about gunboats, you assume the whole region is unstable so your corporate management view might be more negative than it should be,' he said.
