An Eni SPA-led group said a gas discovery offshore northern Mozambique has opened a new play in Eocene sand and hiked the overall potential of the Mamba complex to 47-52 tcf of gas in place.
The Coral-1 well went to 4,869 m in 2,261 m of water. The wellsite is 65 km off Capo Delgado in the southern part of Area 4 and 26 km southeast of the group’s Mamba South-1 discovery.
The well, which encountered 75 m of gas pay in a single, high-quality Eocene sand, is to be production-tested. The Coral prospect holds an estimated 7-10 tcf in place, Eni said, and the resource exclusively located in Area 4 is 15-20 tcf in place.
Eni will drill at least five more wells to fully establish Area 4’s upside potential.
Eni is the 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.
