Eni has started production from Nené Marine field, offshore Congo, just eight months after obtaining the production permit and 16 months following the exploration discovery.
The 1.5 billion boe field, in Marine XII Block, about 17 km from the coast and in 28m water depth, is expected to reach a production plateau of 140,000 boe/d from over 30 production well.
First production is from a single platform, tied back to the Zatchi production platform, also operated by Eni, via a 17km-long subsea pipeline. More platforms will be added to the development in the future.
The Nené Marine field produces from Djeno pre-salt formation 2.5 km below the ground level. During the production test Nené Marine 3 well delivered in excess of 5000 bo/d with a density of 36° API.
Eni says that in recent years it has discovered about 3.5 billion barrels of oil equivalent of resources in the Congolese Marine XII Block.
Eni's latest discovery offshore Congo was made just over a month ago through the Minsala Marine 1 exploration well, which produced over 5000 bo of light oil with a density of 41° API.
Eni has been operating in Congo since 1968 and currently produces about 110,000 barrels of oil per day of equity production.
Eni, through its own subsidiary Eni Congo SA, is operator of Marine XII with a 65% share stake. The other partners are New Age (25%) and Société Nationale des Pétroles du Congo (10%).
