Italian oil and gas company Eni has announced the fifth light oil discovery in Block 15/06, offshore Angola.

The company discovered the new resource by drilling a well in the Agidigbo exploration prospect.

Based on drilling results, the preliminary analysis indicates that the discovery hosts between 300 and 400 million barrels of light oil.

The Agidigbo-1 NFW was drilled by the West Gemini drillship to a total depth of 3,800m. It encountered a single hydrocarbon column composed by a gas cap ranging from 60m to 100m.

The hydrocarbons are located in the Lower Miocene sandstones with good petrophysical properties. Eni noted that the discovery has further upside potentiality, which will be confirmed by an appraisal campaign planned in early next year.

Furthermore, production from the Agidigbo discovery can be fast-tracked by using East Hub’s facilities and subsea network, located around 10km away.

The Agidigbo resource follows the discoveries of Kalimba, Afoxé, Agogo and Ndungu in offshore Angola. The Ndungu prospect was discovered last month.

All of these resources were identified by the Block 15/06 joint venture (JV) after the resumption of exploration activities a year ago.

“The preliminary analysis indicates that the discovery hosts between 300 and 400 million barrels of light oil.”

Overall, the five discoveries are estimated to host up to 1.8 billion barrels of light oil.

The Block 15/06 JV is operated by Eni with a 36.8421% stake. Sonangol P&P (36.8421%) and SSI Fifteen (26.3158%) are the remaining stakeholders.

The block features two oil development projects, the West Hub and East Hub, with a combined production of nearly 155,000 barrels of oil a day.
