ENI adds to Mozambique finds

Italy's ENI announced another new gas discovery in the Mamba Complex offshore Mozambique.

The firm said the discovery, made at the Coral 3 delineation well, confirmed the potential of the Mamba Complex in Area 4 at 75 trillion cubic feet (tcf) of gas in place.

The Coral 3 well was the eighth well drilled back to back in Area 4. It was drilled in 2,035m of water and reached a total depth of 5,270m. The well is located approximately 5 km south of Coral 1, 15km from Coral 2, and approximately 65km off the Cabo Delgado coast. It encountered 117m of gas pay in a high quality Eocene reservoir and adds at least 4 Tcf of gas in place to Area 4, said ENI.

ENI said: "The discovery proved the existence of hydraulic communication with the same reservoir of Coral 1 and Coral 2 and confirms the giant size of the Coral discovery that is now estimated to contain 13 Tcf plus of gas in place wholly located in Area 4. Coral wells deliverabilities showed during the production tests are excellent and each well is expected to deliver very high flow rates in production configuration."

Eni plans to drill another delineation well, Mamba South 3, in order to assess the full potential of the Mamba Complex discoveries, before moving back to exploration drilling in the southern sector of Area 4.

Eni is the operator of Area 4 with a 70% participating interest. The other partners of the joint venture are Galp Energia (10%), KOGAS (10%) and ENH (10%, carried through the exploration phase).
