Italy-based oil company Eni has confirmed that the discovery of gas in the exploratory prospectus of Mamba South 1, Area 4 offshore Mozambique is about 50% larger than what was announced by the firm last month.
The company encountered a new separated pool containing a potential of up to 7.5Tcf of gas when the well was being deepened.

The new sequence has been cored and contains about 90m of gross gas pay.
Eni plans to drill the well to a total depth of about 5,000m and considers the discovery to have a potential of up to 22.5Tcf of gas in place.
Once the drilling and testing activities are completed, Eni will move the rig to drill the second commitment well, Mamba North 1.
Eni is the operator of Offshore Area 4 with a 70% stake while Galp Energia, Kogas and ENH each own a 10% interest.
