Russian natural gas company OAO Gazprom has set its sights on becoming one of the top 15 natural gas marketers in the U.S., www.marketwatch.com reported. The company expects to handle volumes of around 1 billion to 3 billion cubic feet a day or more once Russian exports of liquefied natural gas, or LNG, start flowing around the end of the decade. The company will consider investing in regasification facilities, but so far has no concrete plans to do so. Gazprom, the world's largest natural gas producer, supplies about a quarter of Europe's natural gas and has begun to set its sights further afield. In the U.S., that will mean pursuing a fully integrated strategy. Russia isn't exporting any LNG yet.
