Maputo — The Italian energy company, ENI, has announced a further massive discovery of natural gas in the Rovuma Basin, off the coast of the northern Mozambican province of Cabo Delgado.
According to a Monday press release from ENI, the new discovery was made at the Mamba North East 1 exploration well in the eastern part of Area 4 of the Rovuma Basin. The results from this well, ENI says, increase the resource base of Area 4 by at least 10 trillion cubic feet of gas, bringing the total amount discovered by ENI from three wells in Area 4 to at least 40 trillion cubic feet.
The Mamba North East 1 well is 50 kilometres east of the Cabo Delgado coast. The water here is 1,848 metres deep, and the well was drilled to a depth of 4,560 metres. This well is 15 kilometres north-east of Mamba South 1 and 12 kilometres south-west of Mamba North 1 - the two wells where ENI's earlier discoveries were made Mamba North East 1, according to the ENI release, "encountered a total of 240 meters of gas pay in multiple high-quality Oligocene and Eocene sands and proved reservoir continuity and pressure communication with Mamba South 1 and Mamba North 1 wells".
ENI plans to drill at least another four wells in Area 4 later this year.
ENI is the operator of Area 4, with a 70 per cent participating interest. Its partners are Galp Energia of Portugal, Kogas of South Korea, and Mozambique's own National Hydrocarbon Company (ENH), each of which has a 10 per cent share.
If one adds together the discoveries announced by ENI, and those made by the US company Anadarko (in Area 1 of the Rovuma Basin), the total gas reserves discovered so far amount to over 70 trillion cubic feet.
