Energy companies British Petroleum and Eni announced Thursday a significant natural gas discovery off the Egyptian coast in the Baltim southwest exploration prospect in the East Nile Delta, Youm7 reported. Italy's Eni, through its subsidiary IEOC, holds a 50 percent stake in the licence of Baltim South and BP holds the other 50 percent. The new discovery further confirms the significant potential of the so called Great Nooros Area, which is now estimated to hold 70-80 billion cubic metres of gas in place, Eni said in a statement.
