San Donato Milanese, Italy – Eni has a new natural gas discovery at Manba North 1 offshore Mozambique in Area 4. A mineral potential of 212.5 bcm (7.5 tcf) in place is estimated.

The Mamba North 1 discovery reached TD of 5,330 m (17,487 ft) and is in water depths of 1,690 m (5,545ft) 23 km (14 mi) north of Mamba South 1 discovery and 45 km (28 mi) off the Capo Delgado coast. The discovery well encountered a total of 186 m (610 ft) of gas pay in multiple high-quality Oligocene and Paleocene sands.

During the production test, the first performed at offshore Rovuma, the well produced high quality gas with flow rates, constrained by surface facilities, of about 1 MMcm/d (35.3 MMcf/d) and minor volumes of condensates. In a final production completion configuration, estimated gas production per well is expected to exceed 4 MMcm/d (141 MMcf/d).

During 2012, Eni plans to drill at least other five wells in nearby structures to assess the upside potential of Mamba Complex.

Eni is the operator of Offshore Area 4 with a 70% participating interest. Co-owners in the area are Galp Energia (10%), KOGAS (10%), and ENH (10%, held through the exploration phase).

Eni follows Anadarko in reporting huge gas finds offshore Mozambique.
