August 1, 2012. Eni announced a new giant natural gas discovery in the eastern part of Area 4, offshore Mozambique, at the Mamba North East 2 exploration prospect. This is the fifth exploration well successfully drilled in the area. The new discovery adds at least 10 trillion cubic feet (Tcf) of gas in place to Area 4, confirming at least 62 Tcf of gas in place already discovered. The resources exclusively located in Area 4 are at least 20 Tcf plus of gas in place. This result further increases the total potential of the discoveries of Area 4, which is now estimated at 70 Tcf of gas in place.
