Eni has made a new light oil discovery in Block 15/06, in Angola’s deep offshore. The well was drilled on the Ndungu exploration prospect. The new discovery is estimated to contain up to 250 million barrels of light oil in place, with further upside.
The Ndungu-1 NFW well is located a few kilometres from Eni’s West Hub facilities and has been drilled by the Poseidondrillship in a water depth of 1,076 metres and reached a total depth of 4,050 meters. Ndungu-1 NFW proved a single oil column of about 65 metres with 45 metres of net pay of high-quality oil (35° API) contained in Oligocene sandstones with excellent petrophysical properties. The result of the intensive data collection indicates a production capacity in excess of 10,000 barrels of oil per day.
Ndungu is the first significant oil discovery in Angola inside an already existing Development Area. It certifies the concrete validity of the recent legislation, promoted through the Presidential Legislative Decree No. 5/18 of 18 May 2018, which defines a favourable legal framework on additional exploration activities within existing Development Areas.
Being located about 2 km from the Mpungi field, the new discovery can be fast-tracked to production due to the proximity to the subsea production system. Production will be routed to the N’goma FPSO, therefore extending the West Hub’s production plateau.
Ndungu is the fourth discovery of commercial nature since the Block 15/06 Joint Venture re-launched its exploration campaign in mid-2018. It follows the discoveries of Kalimba, Afoxé and Agogo; the four discoveries altogether already estimated to contain up to 1.4 billion barrels of light oil in place. The appraisal phase of these discoveries will target their additional upside.
These important discoveries further demonstrate the upside potential of the block and the effectiveness of the proprietary technologies that Eni used and will use to explore Block 15/06.
The Block 15/06 Joint Venture, composed by Eni (operator, 36.8421%), Sonangol P&P (36.8421%) and SSI Fifteen Limited (26.3158%), will work to fast track its development.
