Italy-based oil and gas company Eni has made a new gas discovery at its Coral-1 exploration prospect in Area 4 off Mozambique.

The well, located 65km off the Capo Delgado coast, lies around 26km south-east of Eni’s Mamba South-1 discovery.

Drilled to a total depth of 4,869m in a water depth of 2,261m, Coral-1 encountered 75m of gas pay in single high-quality Eocene sand.

"The well, located 65km off the Capo Delgado coast, lies around 26km south-east of Eni’s Mamba South-1 discovery."

Eni said it estimates the Coral prospect discovery to contain between seven trillion and ten trillion cubic feet (tcf) of gas in place.

With these new results at Coral-1, the Italian firm estimates the resources at between 15 and 20 tcf of gas in place.

The company said the new discovery further increases the total potential of the Mamba complex discovered so far in Area 4 Offshore Rovuma, which is now estimated to hold between 47 and 52 tcf of gas.

This discovery is particularly significant, since it confirms a new exploration play, which is independent of those drilled so far in previous Mamba wells, Eni said.

Eni plans to run a production test on the Coral-1 discovery, with at least another five wells scheduled to fully establish the resource potential of Area 4.

Eni operates Area 4 with a 70% participating interest, along with partners Galp Energia (ten percent), Kogas (ten percent) and ENH (ten percent, carried through the exploration phase).
