Italian oil and gas company Eni has made the fifth oil discovery in one year in Block 15/06, through the Agidigbo-1 NFW well in Angola's deep offshore.

It follows the discoveries of Kalimba, Afoxé, Agogo and Ndungu. The five discoveries altogether are estimated to contain up to 1.8 billion barrels of light oil in place.

The well has been drilled on the Agidigbo exploration prospect, and analysis of post drill results indicate between 300 and 400 million barrels of light oil in place.

The Agidigbo-1 NFW has been drilled by the West Gemini drillship in a water depth of 275 meters, and reached a total depth of 3,800 meters. It proved a single hydrocarbon column composed by a gas cap of about 60 meters and 100 meters of light oil with an oil down to.

The hydrocarbons are contained in the Lower Miocene sandstones with good petrophysical properties. The discovery has further upside that will be proved by an appraisal campaign planned in early 2020.

Due to its proximity to East Hub’s facilities and subsea network, which are at about 10 kilometers away, production from Agidigbo can be fast-tracked, thus extending the Armada Olombendo FPSO production plateau.

Block 15/06 partners include Eni (operator, 36.8421%), Sonangol P&P (36.8421%) and SSI Fifteen Limited (26.3158%).
