Eni group adds 4 tcf at Coral offshore Mozambique

A group led by Eni SPA has elevated the gas potential of the Mamba Complex in Area 4 offshore Mozambique to 75 tcf in place with drilling of the Coral-3 delineation well.

Coral-3 encountered 117 m of gas pay in a high-quality Eocene reservoir and adds at least 4 tcf of gas in place to Area 4. Eni said the well “confirms the potential of Area 4 operated by Eni at 75 tcf of gas in place, of which 27 tcf is exclusively located in Area 4.”

The Eni group drilled Coral-3 to 5,270 m in 2,035 m of water 5 km south of Coral-1, 15 km from Coral-2, and 65 km off the Cabo Delgado coast. It is the eighth well drilled back to back in Area 4.

The discovery proved the existence of hydraulic communication with the same reservoir encountered in Coral-1 and 2 and results in a new estimate of 13+ tcf of gas in place in the Coral discovery solely in Area 4.

The deliverabilities demonstrated by the Coral wells during production tests were excellent, and each well is expected to flow at very high rates in production configuration, Eni said.

Eni plans to drill the Mamba South-3 delineation well in order to assess the full potential of the Mamba Complex discoveries before moving back to exploratory drilling in the southern part of Area 4.

Eni is operator of Area 4 with a 70% participating interest. Galp Energia and Korea Gas Corp. have 10% each, and Mozambique’s state ENH has 10% carried through the exploration phase.
