After Russian Oil flows through the various pipelines described above, Crude Oil and products are shipped onward to Europe, the United States, and Asia via tanker. The bulk of Russias oil is shipped to the Mediterranean and to Asia via tankers in the Black Sea, mostly from the port of Novorossiysk. With the opening of the BTC Pipeline in early 2006 and the higher export aspirations of the CPC consortium owners , it is now unclear how much oil will still be shipped out of the Black Sea ports. Since the economic viability of the BTC pipeline is as of yet untested, some analysts expect Novorossiysk (along with Batumi, Supsa, and Odessa) to remain at current levels (approximately 1.7 million bbl/d in 2003). Other analysts expect that if Azerbaijan does actually divert all of its oil shipments via BTC, the exports from Novorossiysk will decrease. News reports indicate a floating proposal that the Baku-Novorossiysk line might then be reversed, allowing for 250,000 bbl/d more crude oil exports to be sent from Russia to Baku and then along the BTC route. Also, the only area of expansion in the Russian pipeline network is near St. Petersburg, and the Baku-Novorossiysk line is the only one with spare capacity.
