BG Group says Tanzania holds at least 15 trillion cubic feet of gas LONDON, Dec. 10 (UPI) -- British energy company BG Group said Tuesday it estimated there are 15 trillion cubic feet of natural gas in its reserve basins off the Tanzanian coast. The company said Tuesday its latest discovery, dubbed Mzia, off the southern Tanzania coast holds an estimated 4.7 trillion cubic feet of total recoverable natural gas. The company said that brings its total estimate for reserves spread out over three areas to around 15 trillion cubic feet. BG Group Chief Executive Officer Chris Finlayson said he expected the Tanzanian government to lay out eventual plans to build an export terminal for the country's natural gas resources. Export plans with its partners at British energy company Ophir Energy and Norway's Statoil call for deliveries of liquefied natural gas. Statoil last week announced it discovered more than 2 trillion cubic feet of natural gas at its Mronge-1 reserve area off the Tanzanian coast. The U.S. Energy Information Administration said in an April profile of Tanzania the country doesn't export natural gas but recent discoveries have increased its potential to become a gas exporter.
