Eni upgrades resource base offshore Angola

Eni SPA upgraded the resource base in Ndungu field, about 130 km off the coast and about 10 km from the Ngoma FPSO in the West Hub of Block 15/06, offshore Angola.

The Ndungu 2 appraisal well was drilled 5 km from Ndungu 1 and struck 40 m net oil pay (35°API) in the Lower Oligocene reservoirs with good petrophysical properties confirming the hydraulic communication with the discovery well. Intensive data acquisition was performed to assess the discovery's full potential.

Preliminary data increases field resources to 800–1,000 MMboe in place from initial estimates of 250-300 (post Ndungu 1), making Ndungu, together with Agogo, the largest accumulation discovered in Block 15/06 since the block award. Ndungu field development will be upgraded following a phased approach, initially extending and increasing plateau of the Ngoma FPSO.

The early production phase of Ndungu started last February through one producer well. A second producer well is expected in this year's fourth quarter, maximizing utilization of existing facilities in the West Hub (OGJ Online, Feb. 25, 2022). In parallel, appraisals will continue to optimize returns and minimize risks, the company said.

Eni Angola operates the block with 36.84% interest. Partners are Sonangol Pesquisa e Produção (36.84%) and SSI Fifteen Ltd. (26.32%).
