A successful appraisal well at the field has boosted reserves estimates as high as 1 billion barrels.

Eni has boosted its reserves base for the Ndungu field in the West Hub of Block 15/06 following the results of an initial well. The Ndungu 2 appraisal well was drilled 5 km away from Ndungu 1 and encountered 40 m of net oil pay in the Lower Oligocene reservoirs with good petrophysical properties confirming the hydraulic communication with the discovery well.

The preliminary data collected on Ndungu 2 allows Eni to boost the field resources to between 800 million and 1 billion BOE in place from the initial estimates of 250–300 million BOE following the discovery well. The upgrade makes Ndungu, together with Agogo, the largest accumulation discovered in Block 15/06 since the block award.

The early production phase of Ndungu started in February through one producer well, and a second producer well is expected in the fourth quarter of 2022, maximizing the utilization of existing facilities in the West Hub.

Ndungu field development will now be upgraded to reflect the increase of the resource base, following a phased approach to uncap the overall potential initially contributing to extend and increase the plateau of the Ngoma—a 100,000 B/D, zero-discharge and zero-process-flaring FPSO.

Block 15/06 is operated by Eni Angola with a 36.84% share. Sonangol Pesquisa e Produção holds 36.84% and SSI Fifteen Ltd., 26.32%.
