The West Hub development project involves the development of Sangos, Cinguvu, Mpungi, Mpungi North and Vandumbu fields in a water depth ranging from 1,000m to 1,500m.

Cinguvu is the second field to come on production after Sangos, which came on line in November 2014.

Eni CEO Claudio Descalzi: "This is indeed another important step within the innovative hub-building strategy at the base of our success in Block 15-06 in Angola.

"A second field, Cinguvu, came on stream on time and on budget, after Sangos in November 2014, confirming our excellent track record in terms of efficiency, technology and innovation."

The wells are connected to the N’Goma floating production storage and offloading unit (FPSO), which has 100,000 barrels of oil per day treatment capacity.

Currently, the Sangos and Cinguvu fields are producing about 60,000 barrels of oil a day through the N’Goma FPSO and are expected to ramp up to 100,000 barrels in the fourth quarter.

The company plans to connect the third field, Mpungi, to N’Goma FPSO in by the end of the year.

Eni operates Block 15/06 with a 35% stake while other partners include Sonangol Pesquisa e Produção (35%), SSI Fifteen (25%) and Falcon Oil Holding Angola (5%).

Daily production of Eni in Angola currently amounts to 105,000 barrels of oil equivalent per day.
