SAN DONATO MILANESE, Italy – Eni has made a light oil discovery in the Ndungu exploration prospect in block 15/06 offshore Angola.
The drillship Poseidon drilled the Ndungu-1 NFW well in a water depth of 1,076 m (3,530 ft) and reached a TD of 4,050 m (13,287 ft).
The well proved a single oil column of about 65 m (213 ft) with 45 m (148 ft) of net pay of high-quality oil (35° API) contained in Oligocene sandstones with “excellent” petrophysical properties.
The new discovery is estimated to contain up to 250 MMbbl of light oil in place, with further upside. Well results indicate a production capacity in excess of 10,000 b/d of oil.
According to Eni, Ndungu is the first significant oil discovery in Angola inside an existing development area. It certifies the concrete validity of the recent legislation, promoted through the Presidential Legislative Decree No. 5/18 of May 18, 2018, which defines a favorable legal framework on additional exploration activities within existing development areas.
Located about 2 km (1.2 mi) from the Mpungi field, Ndungu can be fasttracked due to the proximity to the subsea production system, the company said. Production will be routed to the FPSO N’Goma, extending the West Hub’s production plateau.
Ndungu is the fourth commercial discovery since the Block 15/06 Joint Venture re-launched its exploration campaign in mid-2018. It follows the Kalimba, Afoxé, and Agogo discoveries. The four discoveries are estimated to contain up to 1.4 Bbbl of light oil in place. The appraisal phase of these discoveries will target their additional upside, Eni said.
The Block 15/06 Joint Venture, comprised of Eni (operator, 36.8421%), Sonangol P&P (36.8421%) and SSI Fifteen Ltd. (26.3158%), will work to fasttrack its development.
The West Hub and East Hub projects in block 15/06 are currently producing about 155,000 b/d of oil, according to Eni.
